Crosscutting concerns, aspect-oriented softwaredevelopment, design by contract.
In this paper we discuss the provision of contracts
throughout object-oriented software development in order
to enforce system semantics and provide the means to
achieve verification of requirements in aspect-oriented
software development. The motivation behind this work is
to provide mechanisms whereby developers can (a) attach
formal or semi-formal contractual obligations in the form
of assertions (including invariant clauses) to analysis and
design artifacts in order to enforce semantics and (b) trace
the implementation model to the design model in
accordance with the semantics provided by contract
definitions in order to provide verification of requirements.

Arlie Russell Hochschild (born 15 January 1940) is a professor of sociology at the University of California, Berkeley, in the United States. She is the author of several books and numerous articles, including The Time Bind: When Work Becomes Home and Home Becomes Work (1997) and The Second Shift, which discuss the dual labor by women in both the general economy and within the household. According to her research, the first is rewarded less than the labor of men, while the second is completely unpaid. Arguably her most influential work to the field of sociology has been Emotion Work, Feeling Rules and Social Structure (1979) and subsequently The Managed Heart: Commercialization of Human Feeling (1983).

Is it possible to assign a reference to "this" in java?
JavaObject Oriented ProgrammingProgramming
The "this" keyword in Java is used as a reference to the current object, within an instance method or a constructor. Using it, you can refer the members of a class such as constructors, variables, and methods.
Assigning reference to "this"
According to the definition "this" is a keyword which acts as a reference to the current object (the object from whose constructor/method you are using it), its value id is fixed. Therefore, you cannot assign a new reference value to it. Moreover, it is just a keyword, not a variable.
Still, if you try to it assign a reference value to "this" it leads to a compilation error.
In the following Java program, the class (ExampleClass) has two private variables name, age and, a parameterized constructor which instantiates these variables. From a method named display, we are trying to assign a new value to "this".
 Live Demo
public class ExampleClass {
 private String name;
 private int age;
 public ExampleClass(String name, int age){ = name;
 this.age = age;
 public void display(){
 this = new ExampleClass("krishna", 23);
Compile-time error
On compiling, this program gives you an error as shown below − error: cannot assign a value to final variable this
 this = new ExampleClass("krishna", 23);
1 error

A major cause of overtesting of spacecraft, aerospace and flight hardware during random and swept sine vibration tests is associated with differences between the mechanical impedance of the shaker and mounting fixture, and the standard practice of controlling the input acceleration to the frequency envelope of the flight data. The result is artificially high shaker forces and responses at the resonance frequencies of the test item. These high forces can damage expensive payloads.
To alleviate the problem of overtesting, it has become common practice to notch the input acceleration, in order to limit the responses in test to those predicted for launch into space. In simple terms, to notch means to reduce the amplitude of the shaker input near the resonant frequencies of the test item. However, this creates a paradox because there are multiple resonant points on complex structures and determining these resonant points on the structure is very much dependent on analysis, which the vibration test is supposed to validate.
Another challenge in vibration response testing is that it requires placing accelerometers on the test item at all critical locations, each having its own unique resonant response, and many locations can be inaccessible. Since each location will have a different resonant frequency and exceed the control limits at some point during the test, it is often difficult to determine from which accelerometer the test engineer should control the shaker.
Force Limited Vibration (FLV) testing is an alternative that improves the vibration testing approach based on measuring and limiting reaction force between shaker and test item. By using this method, the acceleration input to the test item is automatically notched at the equipment resonances by limiting shaker force values to those predicted for actual flight. Such notching, as it is described here, is based on the premise that mechanical impedance of payloads and the mounting structures are typically comparable for lightweight aerospace structures. FLV testing provides the test engineer with an opportunity to mirror structural response as seen during actual flight hardware mounting applications.
Accelerometers also may be used in the control loop. They serve to limit shaker excitation with respect to acceleration at frequencies other than resonances for which force limiting prevails. In order to accomplish this, the shaker control system must have "extremal control" capability. Extremal control is the ability to establish feedback control with respect to the greater of several inputs, either force or acceleration, as a function of frequency. Several modern day shaker controllers now have this capability.
Force control limits are typically predicted using finite element analysis or actual launch data from prior flights, a safety margin added, and the resultant values are used to control the force input. So, instead of a control accelerometer, the test engineer uses piezoelectric force sensor control.
The three-component piezoelectric charge output force sensors can be mounted between the shaker and unit under test. The charge output must connect via multiple cables, which are routed and summed in special summing boxes, and then feed into multiple charge amplifiers. Also visible are accelerometers with built-in amplifier, placed at critical points on the structure, to monitor structural response.
The same ICP technology used for accelerometers is now available for these three-component force sensors. The benefits include easier cable management, hermetic sealing, simplified summing amplifiers and reduced overall labor cost to perform the testing.
The use of three-component force sensors to simulate real conditions and force limit shaker inputs via the notching method minimizes the chance of overtesting and damage to spacecraft or other lightweight aerospace structures. It is now possible to provide three pre-summed, low-impedance input signals to the shaker controller, to correctly notch the acceleration input to the test item, without the burden of running multiple cables. It also reduces the great care required when handling more traditional charge output force sensors.

Global Warming
Trouble brewing: Climate change threatens world beer production
By Shaun Smillie 18 October 2018
Beer in glass on the beach in sunset (Anna Latseniuk via Flickr)
In a parched future the speakeasy, that throwback to Prohibition, might once again become the watering hole of the desperate and thirsty.
Nearly 100 years ago, speakeasies were where Americans would find black-market alcohol at a time when the US had decided to go dry.
They were the shebeens of their day.
But black-market alcohol might be a thing of the future if climate change causes the price of beer to spiral out of control.
The price of a brewski will increase dramatically, according to new research, and it is going to come at a time when humankind will be thirsty as it faces killer heatwaves.
If you think what happened in the US in the 1920s with the Prohibition era it was caused by different things, but the consequences were the same," says Dabo Guan, professor of climate change economics at the University of East Anglia's School of International Development. "One was a man-made error and the other will be caused by God."
These acts of God will be droughts and heatwaves — climate change believers say this will ultimately be from the hand of man.
Guan and an international team of scientists have released a first-of-its-kind study into how severe climate events will cause shortages in the world's beer supply. It makes for scary reading. In some countries, beer prices won't just double: Climate change could push up the cost of a can of lager by sixor seven-fold.
What Guan and his colleagues did was look at barley crop production to get a handle on how climate change might effect beer prices and consumption. Barley is a main ingredient in beer, and is easier to model than other beer staples such as hops.
The idea for the study, Guan admits, came about while he and his friends were having a couple of cold ones in Beijing, China.
We were talking about climate change and food and then we thought no one has done anything on alcoholic drinks. And we thought which one should we look at and as we all like beer…" said Guan.
There is a serious side to the study. The researchers had noticed that climate change was seen as a poor person's problem that would have an impact on food security in developing countries.
By highlighting the effect on beer, they believed it would show how global warming would impact developed countries and luxury goods such as chocolate, coffee and beer.
In a worst-case scenario where temperatures increased by four to six degrees Celcius the researchers found a country like Ireland would see beer prices double in the supermarket from $2.50 to $5.00.
Other countries will fare far worse.
In Poland, Estonia and the Czech Republic relative price changes are going to be huge. From US 70c right now from the supermarket to $3.50 a bottle," says Guan.
South Africa will have it bad too. The worst-case scenario has beer prices increasing by 80%.
With price increases will come reduced consumption. Their research suggests that global beer consumption will fall by 16%. Some traditional beer-drinking countries will be particularly hard hit. Germany and UK beer drinking could fall by a third.
Drinking less beer might be a good thing, some might say, but this beverage has been with us probably from the dawn of the agricultural revolution. It is ingrained in some cultures.
Beer is an important tool for social entertainment and even stability," explains Guan.
But in a climate change-affected world the quest for a cheap beer might require dealing with the future's equivalent of Al Capone. Illegally brewed black market beer might become the lager lout's option for a cheap pint.
South African beer expert and author Lucy Corne points out that illegally made alcohol can be dangerous. In Mozambique several years ago, party-goers died when they drank home-brewed beer that had been fortified with something toxic. Already, Corne says, the local craft industry is under strain because of price constraints and competition from international beer companies now importing their own craft beers.
This comes as South Africa, like many other parts of the world, has experienced a recent craft beer revolution which has offered a tasty alternative to the mass-produced lagers that the giants of the brewing industry have flooded the markets with.
Smaller craft beer producers would be harder hit by climate change.
It would be sad if we had to use genetics or chemicals to make beer taste like beer because the ingredients are too expensive. It would definitely be kind of sad," says Corne. DM

In geometry, the trigyrate rhombicosidodecahedron is one of the Johnson solids (J75). It can be constructed as a rhombicosidodecahedron with three pentagonal cupolae rotated through 36 degrees. Related Johnson solids are the gyrate rhombicosidodecahedron (J72) where one cupola is rotated, the parabigyrate rhombicosidodecahedron (J73) where two opposing cupolae are rotated and the metabigyrate rhombicosidodecahedron (J74) where two non-opposing cupolae are rotated.
The 92 Johnson solids were named and described by Norman Johnson in 1966.

Spanish and Scottish researchers have added wool fibres to the clay material used to make bricks and combined these with an alginate, a natural polymer extracted from seaweed. The result is bricks that are stronger and more environmentally-friendly, according to the study published recently in the journal Construction and Building Materials.
"The objective was to produce bricks reinforced with wool and to obtain a composite that was more sustainable, non-toxic, using abundant local materials, and that would mechanically improve the bricks' strength," Carmen Galán and Carlos Rivera, authors of the study and researchers at the Schools of Architecture in the Universities of Seville (Spain) and Strathclyde (Glasgow, United Kingdom), said.
The wool fibres were added to the clay material used in the bricks, using alginate conglomerate, a natural polymer found in the cell walls of seaweed. The mechanical tests carried out showed the compound to be 37% stronger than other bricks made using unfired stabilised earth.
The study, which has been recently published in the journal Construction and Building Materials, was the result of close collaboration between the British and Spanish universities. The clay-based soils were provided by brick manufacturers in Scotland, which was also the source of the wool, since the local textile industry cannot use everything it produces. "The aim was to produce a material suitable for adverse climatic conditions, such as the specific ones in the United Kingdom," the authors explain.
Advantages of environmentally-friendly bricks
The researchers studied the effect of reinforcing various soil types with sheep's wool, and arrived at various conclusions. "These fibres improve the strength of compressed bricks, reduce the formation of fissures and deformities as a result of contraction, reduce drying time and increase the bricks' resistance to flexion."
This piece of research is one of the initiatives involved in efforts to promote the development of increasingly sustainable construction materials. These kinds of bricks can be manufactured without firing, which contributes to energy savings. According to the authors: "This is a more sustainable and healthy alternative to conventional building materials such as baked earth bricks and concrete blocks."
Untreated clay was one of the earliest building materials to be used by humankind. The oldest examples of this can be found in houses in the Near East dating from between 11,000 and 12,000 years ago. Earthy material mixed with plants and pebbles to make them stronger has also been found in certain archaeological deposits from 1400BCE in Sardinia (Italy).

Radeon HD 7870 Overclock Guide
Posted by Hilbert Hagedoorn on: 03/05/2012 02:00 PM [ 0 comment(s) ]
Graphics card Noise Levels
When graphics cards produce a lot of heat, usually that heat needs to be transported away from the hot core as fast as possible. Often you'll see massive active fan solutions that can indeed get rid of the heat, yet all the fans these days make the PC a noisy son of a gun. Do remember that the test we do is extremely subjective. We bought a certified dBA meter and will start measuring how many dBA originate from the PC. Why is this subjective you ask? Well, there is always noise in the background, from the streets, from the HD, PSU fan etc etc, so this is by a mile or two an imprecise measurement. You could only achieve objective measurement in a sound test chamber.
The human hearing system has different sensitivities at different frequencies. This means that the perception of noise is not at all equal at every frequency. Noise with significant measured levels (in dB) at high or low frequencies will not be as annoying as it would be when its energy is concentrated in the middle frequencies. In other words, the measured noise levels in dB will not reflect the actual human perception of the loudness of the noise. That's why we measure the dBA level. A specific circuit is added to the sound level meter to correct its reading in regard to this concept. This reading is the noise level in dBA. The letter A is added to indicate the correction that was made in the measurement. Frequencies below 1kHz and above 6kHz are attenuated, whereas frequencies between 1kHz and 6kHz are amplified by the A weighting.
|TYPICAL SOUND LEVELS|
|Jet takeoff (200 feet)||120 dBA|
|Construction Site||110 dBA||Intolerable|
|Shout (5 feet)||100 dBA|
|Heavy truck (50 feet)||90 dBA||Very noisy|
|Urban street||80 dBA|
|Automobile interior||70 dBA||Noisy|
|Normal conversation (3 feet)||60 dBA|
|Office, classroom||50 dBA||Moderate|
|Living room||40 dBA|
|Bedroom at night||30 dBA||Quiet|
|Broadcast sstudio||20 dBA|
|Rustling leaves||10 dBA||Barely audible|
There's a lot of differences in measurements amongst websites. Some even place the dBA meter 10cm away from the card. Considering that's not where your ear is located, we do it our way.
For each dBA test we close the PC/chassis and move the dBA gun 75 cm away from the PC. Roughly the same proximity you'll have from a PC in a real-world situation. Above, the IDLE (desktop mode) results where the GPU hardly has to do anything.
Now the HIGH IDLE results with the voltage tweaked card is due to the fact that we forced fan RPM at 65% continuously. That value can be anything you wish of course. But we wanted optimal cooling.
For the card in a fully stressed status (in-game) with the overclock applied we measure 43 DBA almost touching 44 DBa, now that is quite audible. The reason for this is that we increased and forced fan RPM towards 40%. The plus is that temps are great, the downside.. added noise.
So my advise is, try to find an RPM level that is acceptable for you, and then see how far you can overclock based on that noise level.
We test and review the MSI Radeon HD 7790 OC edition, also known under SKU code R7790-1GD5-OC incl FCAT Frametimes. The new graphics card is intended to boost a little more performance into entry-level gaming.

Philly Youth Radio won a $600 grant at Stake #6
Philly Youth Radio
1. Describe the project a STAKE Grant would help you accomplish (100 words):
Philly Youth Radio (PYR) is a project that works with a diverse group of local high school students to produce radio stories about their lives and communities. Through a series of intensive radio workshops, students work closely with professional radio producers to create broadcast-quality stories that have been aired on major media outlets. Our hope is that these stories will promote intergenerational, intercultural dialogue, as well as better understanding about young people's experiences and contributions in this city. PYR runs project-to-project and a STAKE grant would move us one step forward in beginning our third season.
2. How will you use the grant toward the realization of your project? $750 is your imaginary budget (50 words):
For PYR's third season, we plan to teach a series of intensive radio production workshops in which we pair youth radio apprentices with adult students to create collaborative audio/visual stories about love and relationships.
Youth radio apprentice stipends: $400
Teaching materials: $150
Outreach materials/listening showcase: $100
3. A little about yourself and what led you to your current creative goals. This may include a previous project of yours, ways it both succeeded and failed (this can be entirely unrelated to your proposal) (100 words):
Yowei Shaw is a freelance reporter and audio producer. Beth Patel is an independent audio producer and youth advocate. PYR's first installment, "Students of Violence," has been featured on alt.NPR's YouthCast, Generation PRX, WHYY, and other media outlets. The overwhelming response to our first project prompted a second "season" of PYR in 2012, titled "Teen Sanctuaries." Our main challenges include a shortage of time and funding. We feel that we could create better stories with our students if we had more time to work on them together. However, without adequate funding, we make do with the time that we have.
4. Why is this project important? How will it benefit the community? (100 words):
This project helps project the voices of young people in our communities. We ask students to discuss issues that matter to them and then help share their stories on a larger stage. Throughout the process, students improve their writing, editing, and voicing – skills that will be useful long after the project has ended. Most importantly, our students learn to collaborate with adults in a reporter/editor relationship formed through mutual respect and dedication to the best story possible. We feel that our students are leaders in their respective communities and that PYR is important to shaping that leadership.

Description of Wisdom
The Wisdom symbol consists in an arrow, of which the shaft is a wavy or meandering line. The arrow moves at a slight diagonal and the arrowhead is pointing downwards and to the left. This represents wisdom and specifically a person who is wise and true to themselves. If the arrowhead were to point downwards and to the left, the symbol would represent far-sight and impressive powers of observation.
General American Native Rock Art description American Native Rock Art is found predominantly in the Southwest United States of America. Utah, New Mexico and Tesco also contain a significant number of surviving occurrences. All are either pictographs: drawings or paintings made on rocks; or petroglyphs: images carved into the rock. Native Rock Art found in the United States of America can date from as long ago as 3000 BC. Much of it is extremely ancient, while more recent examples contain symbols that are common to many tribes, and so it is hard to say much that is definitive about the peoples who made these images. Some symbols stood for human character traits, like wisdom or far-sightedness, while others represent abstract concepts such as wealth or creativity. Other symbols told myths and histories that involved the tribe's travels, achievements or successful hunting expeditions. Some, likely, serve as warnings. Though some of these symbols were carved onto stone, at least one belief system says that the stones themselves are bodies of the 'stone people'. Legends hold that the symbols were burned into the stone people by the gods using lightning strikes. Many large Native American rock carvings and pictographs still exist to this day, and are treated as significant cultural and historical artefacts in the United States of America.

For instance, a firearm's firing would not make an explosive sound, but if you cast this spell on a creature's bite attack, it would not prevent it from vocalizing from its mouth. The first time a creature is struck by a weapon affected by this spell, it must succeed at a Will save (SR applies to this effect) or it becomes unable to make noise louder than a whisper (Perception DC 10 to hear) whether vocally or by other means for the duration of the effect. Because the creature can still whisper, this doesn't interfere with verbal spell components. Whether it succeeds or fails its saving throw, the creature is immune to further effects from this casting of quieting weapons.

Relay For Life is the celebration of cancer survivorship and the support of caregivers throughout the cancer journey. Relay For Life honours and celebrates the hope that cancer survivors and caregivers give others fighting cancer.
O – OFFER OPPORTUNITIES TO BE INVOLVED WITH CANSA
The energy and spirit of Relay For Life encourages meaningful year-round volunteer involvement and is a powerful way for individuals to remain involved with the CANSA mission. Involving more people in our life-saving work is crucial. Relay For Life is a great way to get survivors and caregivers to stay involved with CANSA year-round. Make them excited them about their role in the fight against cancer and help them explore how they can do this.
P – PROVIDE HOPE THROUGH INFORMATION, EDUCATION AND SERVICE
Relay For Life is about empowering participants to learn more, share more and do more in the fight against cancer. Through Relay, we provide quality information about community programmes and services that connect cancer survivors and caregivers to the CANSA service.
E – ENGAGE SURVIVORS & CAREGIVERS AS ACTIVE CANSA VOLUNTEERS
Relay For Life is not only about walking around a track, but to survivors and caregivers the steps taken at this life changing event are just the first of many opportunities to provide hope to others fighting cancer. It is important to invite, excite and explore these opportunities to help connect survivors and caregivers with the many ways that they can deepen their involvement with CANSA.
Share your story of hope and encouragement on Champions of Hope – CANSA Survivors Facebook group. (For all cancer survivors or caregivers)
Relay For Life Caregiver Initiative
Caregivers Providing Support – Touching People's Lives
Attention ALL Caregivers:
A caregiver is anyone who has provided daily care for someone with cancer, as a family member, friend or essential healthcare professional might. Caregivers are also those who have provided assistance or support for someone with cancer such as emotional support, transportation, helping with chores or meals, spiritual guidance, etc. No matter the type or extent of support provided, caregivers are "get it done" people who truly understand the magnitude of a cancer diagnosis, the importance of being there and of community. This understanding and the value of the care they provide is never diminished regardless of whether they are currently providing that care, their survivor or loved one is cancer free or their loved one is no longer with them. Each is a caregiver who deserves the opportunity to be thanked and recognized. All caregivers are important! If you think that sounds like a broad definition, you're right! If you think that sounds like nearly everyone you know, you're right! We know that many people already attending our events are caregivers. So how do we set out to create that atmosphere of appreciation, recognition, and support for those special people?
Creating an Atmosphere of Appreciation, Recognition & Support:
Relay offers numerous opportunities to create an atmosphere welcoming to all caregivers. Included here are a few suggested ways to help you get started.
- Treat caregivers to their own Welcome Center offering a thank you card, punch or deserts and a special caregiver activity (i.e. craft handmade flowers for Gratitude Garden, create personalized caregiver/love one buttons, caregiver handprint banner, etc…)
- Create a Gratitude Garden that contains handmade flowers with the survivor or caregivers' name in the center and the names and actions of caregivers on the petals.
- Create a Caregiver handprint wall/banner for messages to be written.
- Thank caregivers for all they do and telling their caregiver story.
- Specifically recruit caregivers to light luminaria or spell out HOPE or CURE Have a caregiver speaker at the survivor reception.
- Create stars with caregiver names and messages and hang in the survivor tent and around the track.
- Have a special caregiver lap inviting all caregivers to participate and ensuring caregivers whose survivors are no longer with are included. Special lap could be as part of opening ceremony or luminaria ceremony.
- Use caregiver banners for ceremonies, special laps and on display.
- Invite a caregiver to speak at your luminaria ceremony and include caregiver defining messaging.
- Create a "caregiver coupon book" that is given out to caregivers when they register. It contains coupons for different on–site activities or fundraisers throughout the day.
- Create a Foster a Caregiver program (for those not on team and those whose survivor is no longer with them).
Messaging: Display track signs defining what a caregiver is.
Messaging: Include caregiver defining messaging in opening ceremonies
Before & After Relay
- Recruit and identify a volunteer to your committee to plan and implement special caregiver activities and messaging.
- Include caregiver messaging in scripts and announcements and invite caregivers to speak at Relay meetings, launch events, etc.
- Offer caregiver coffees (similar to survivor coffees or receptions) throughout the year – honour them, educate them on CANSA offerings and engage them further in Relay.
- Put caregiver stickers on all name tags at meetings and pre–event activities.
- Include in all advertising and marketing caregiver messaging.
- Identify all opportunities to use caregiver defining messaging and promote inclusion of all caregivers.
- We've done a good job of promoting Survivor involvement by explaining just how important Survivors are to Relay For Life events.
- Begin a similar campaign with Caregivers, maybe a catchy slogan and include caregiver messaging.
Messaging: Include caregiver defining messaging in all event communications (email blasts, event website, newsletters, press releases, etc.) in an effort to reach all possible caregivers.
Messaging: If the event has a newsletter, include a small article each month about a caregiver that recognizes them. Include feature articles about caregivers currently providing care, those who have provided care and those whose loved one is no longer with them.

Stencil thickness makes a difference! Thicker stencils allow more paste to be deposited which is good for large parts and connectors but can cause shorts with finer pitch parts.
To calculate the optimal stencil thickness for fine pitch placement, IPC standard #7525 states:
Stencil Thickness = 2.64 + 0.0831 * Pitch of component (in mils)
So, say for an FT232RL chip, which is a SSOP part with 0.65mm pitch. First figure out the pitch in thousands of an inch:
0.65 mm / 25.4 = 0.0256 inches = 25.6 mils
Then calculate according to the equation above
2.64 + 0.0831 * 25.6 = 2.13 + 2.64 = 4.77 mil
So for SSOP parts, 4 to 5 mil is the thickest you should go

Zaqaibeh, Belal Mohammad (2006) Development of an Assertion Model of Integrity Constraints in Object-Oriented Databases. PhD thesis, Universiti Putra Malaysia.
Object-Oriented Databases (OODBs) have been designed to support large and complex programming projects. The data accuracy, consistency, and integrity in OODBs are extremely important for developers and users. Checking the integrity constraints in OODBs is a fundamental problem in database design. Existing OODB Management Systems (OODBMSs) lack to a capability of an ad-hoc declarative specification of enforcing and maintaining integrity constraints that are appeared among attributes in association, composition, and inheritance hierarchies' relationships. A critical problem in the existing OODBs is that they cannot support User-Defmed Constraints (UDCs) that can be defmed in classes with composition (logical or physical composition) and inherence (single or mUltiple inheritance) hierarchies. Integrity constraints in the current OODBMSs are maintained either by disallowing and rolling back transaction or modifying operations that may produce a violation. The constraints must be maintained in the backward direction along the class composition hierarchy as well as in the forward direction. In this work an Assertion Model of Integrity Constraints (AMIC) is proposed. The AMIC keeps the derivation path along with the attributes' relationships that are derived from association, composition, and inheritance hierarchies. The AMIC techniques are designed to implement the needed functions that are collecting the attributes' relationships and checking the integrity constraints. Moreover, AMIC keeps UDCs with their relationships in both single classes and multilevel classes (intra-class and inter-class). Furthermore, the AMIC can maintain constraints in a single object and a set of distributed objects (intra-object and inter-object). Therefore, this makes the new model extendable and can be integrated with any existing constraints' service. A new technique called Detection Method (DM) isdesigned to check the Object Meta Data (OMD) to detect the constraints violation before it occurs. The AMIC is designed for both Centralized Integrity Maintenance (CIM) and Application-Oriented Integrity Maintenance (AOIM). The AMIC can also enforce and maintain structural and logical integrity constraints, in addition to enforce and maintain redundant, inconsistent, and duplicate constraints.

After reading this article about avalons retainment of vector graphic's, I think I understand how it can do cleartype on rotating text, but I was curious if vector objects other than text will support cleartype? I've heard that ClearType is done using a pixelshader in Longhorn, so it seems reasonable that you could do this to other graphical objects as a form of antialiasing.

Minimize Distance between 3D Point Sets with Rotation and Translation
Date: 07/15/2007 at 14:32:21
From: Juan
Subject: find a rot-translation matrix for fitting two 3D point sets
I need to fit two sets of 3D points (a, b, c... n) and (a', b', c'...
n') in such a way that the Euclidean distances between the point
pairs (a,a'), (b,b')...(n,n') is minimum. I can apply only rotations
and translations but no scale changes.
Is it possible to find a least-squares solution to this problem? There
are lots of web pages describing methods for fitting the least-squares
solution between points and functions but I was unable to find
anything between two sets of points.
I suppose that if I represent X as the first dataset and Y as the
second dataset the classic least-squares method
Xt = Y
t = (X^TX)-1 X^T Y
should be able to provide a t matrix. However, this matrix can
contain scaling and I need that the transformation involves only
rotation and translation.
I have tried to use an iterative algorithm that applies rotations and
translations. It works fine, but it's time consuming and I am
convinced that there are far more efficient methods.

What Finland lacks to become a successful culturally diverse country like Canada
by, under Enrique Tessieri
Anti-immigration populists and ultranationalist use the code term "immigration policy" to mean that they don't want non-EU nationals especially Muslims from the Middle East and Africa to move to their country. Finland is no exception and some point to Canada as a good example we could copy when it comes to immigration policy.
Those that make such claims have no idea that Finland's immigration policy is one of the strictest in Europe and they rarely if ever mention that Canada's recipe for success is based on how Canadians perceive multiculturalism or cultural diversity.
Näyttökuva 2016-1-27 kello 9.03.19
Read full story here.
A long time ago I came across an interesting article published by Siirtolaisuus – Migration in 1996 authored by J. W. Berry of Canada. The article, Prejudice, Ethnocentrism and Racism, highlights what is needed for cultural diversity to prosper and why it works in Canada.
Berry states:
(1) there needs to be general support for cultural diversity as a valuable resource for a society;
(2) there should be overall low levels of prejudice in the population;
(3) there should be generally positive mutual attitudes among the various ethnocultural groups that constitute the society;
(4) there needs to be a degree of attachment to the larger national society.
Finland fails, in my opinion, in most of the above points. Too many see cultural diversity as a threat to society and prejudice is pretty standard. Ethnocultural groups appear to want to be a part of society but this may be easier said than done. Using terms like "person with foreign background" or labeling children as outsiders because their parents were born elsewhere are sad examples of exclusion from the larger context of society.
An extreme example of how some Finn want to relegate migrants and minorities to secondand third-class citizens is the Perussuomalaiset (PS)* party and other neo-Nazi and ultranationalist groups. Some of them hope that we will follow Denmark's draconian path.
There are too many examples in Finland and Europe that make Canada look like a different planet when it comes to being a successful and dynamic culturally diverse society.

STUDY ON SUBSYNCHRONOUS RESONANCE PROBLEM IN SERIES-COMPENSATED TRANSMISSION SYSTEM
Chengbing He, Dongchao Chen
School of energy, power and mechanical engineering, North China Electric Power University, Beijing 102206, China
The series capacitor compensation technique can improve the transmission capability of transmission system; however, it may cause subsynchronous resonance (SSR) which will seriously influence the safe operation of large turbo-generator shafts. Aiming at a series capacitor compensation transmission system, the transient torques of SSR is simulated in different compensation degrees and unit load levels. Based on the modified segmentation Prony algorithm (MSPA) proposed in this paper, the characteristic frequencies and damping parameters are identified and analysed. The MSPA, complex Morlet wavelet and time-frequency contour map are integrated and used in analysis of transient torques of SSR in time-frequency field. The results of study show that the transient torques develop towards divergence direction and the frequencies of SSR (converted to the rotor side) in negative damping area move towards into low frequency area with the increasing of the compensation degree. With the increasing of the power output, the torque values of each shaft section will increase, but the dominant oscillation mode will not change. The increasing of power output can make the damping effect slightly change and the trend of the change develops towards the direction that is not conducive to restrain SSR.

Describe how to eliminate or reduce the number of parasites in food.
Cooking foods to minimum safe endpoint cooking temperatures destroys all foodborne parasites. Freezing will also kill some parasites in food.
For example, to destroy parasites in fish that is to be served raw, the fish can be frozen and stored at a temperature of –4 degrees F (-20 degrees C) or colder for 168 (7 days) or frozen at –31 degrees F (-35 degrees C) or colder until solid and stored at –31 degrees F (-35 degrees C) for 15 hours. If the fish are tuna of the species Thunnus alalunga, Thunnus albacares (Yellowfin tuna), Thunnus atlanticus, Thunnus maccoyii (Bluefin tuna, Southern), Thunnus obesus (Bigeye tuna), or Thunnus thynnus (Bluefin tuna, Northern), the fish may be served in a raw, raw-marinated, or partially cooked form without being frozen first.


Love affairs and linear differential equations
Differential equations are a powerful tool for modeling how systems change over time, but they can be a little hard to get into. Love, on the other hand, is humanity's perennial topic; some even claim it is all you need. In this blog post — inspired by Strogatz (1988, 2015) — I will introduce linear differential equations as a means to study the types of love affairs two people might find themselves in.
Do opposites attract? What happens to a relationship if lovers are out of touch with their own feelings? We will answer these and other questions using two coupled linear differential equations. On our journey, we will use graphical as well as mathematical methods to classify the types of relationships this modeling framework can accommodate. In a follow-up blog post, we will also play around with non-linear terms and add a third wheel to the mix, which can lead to chaos — in the technical sense of the term, of course. Excited? Then let's get started!
Introducing Romeo
A lovestruck Romeo sang the streets of serenade
Laying everybody low with a love song that he made
Finds a streetlight, steps out of the shade
Says something like, "You and me, babe, how about it?"
Romeo is quite the emotional type. Let $R(t)$ denote his feelings at time point $t$. Following common practice, we will usually write $R$ instead of $R(t)$, making the time dependence implicit. The process which describes how Romeo's feelings change is rather simple: it depends only on Romeo's current feelings. We write:
which is a linear differential equation. Note that this implicitly encodes how Romeo's feelings change over time, since when we know $R$ at time point $t$, we can compute the direction and speed with which $R$ will change — the derivative denotes velocity. Our goal, however, is to find an explicit, closed-form expression for Romeo's feelings at time point $t$. In this particular case, we can do this analytically:
A differential equation describes how something changes; to kickstart the process, we need an initial condition $R_0$. This allows us to find the constant of integration $C$. In particular, assume that $R = R_0$ at $t = 0$, which leads to:
such that:
The left two panels of the figure below visualize how Romeo's feelings change over time for $a > 0$ with initial condition $R_0 = 1$ (top) or $R_0 = -1$ (bottom). The right two panels show how his feelings change for $a < 0$ with $R_0 = 100$ (top) or $R_0 = -100$ (bottom).
plot of chunk unnamed-chunk-1
We conclude: Romeo is a simple guy, albeit with an emotion regulation problem. When the object of his affection is such that $a > 0$, his feelings will either grow exponentially towards mad love if he starts out with a positive first impression ($R_0 > 0$), or grow exponentially towards mad hatred if he starts out with a negative first impression ($R_0 < 0$). On the other hand, if $a < 0$, then regardless of his initial feelings, they will decay exponentially towards indifference.
For $R_0 = 0$, Romeo's feelings never change. For any other initial condition, we have uhindered, exponential growth when $a > 0$; it never stops. For any other initial condition and $a < 0$, we crash down to zero very rapidly. Thus $R = 0$ is a fixed point in both cases, which is stable for $a < 0$ but becomes unstable if $a > 0$. We can visualize this in phase space on a line. The phase space is filled with all possible trajectories because each point can serve as the initial condition.
plot of chunk unnamed-chunk-2
In the next section, a wonderful new episode in Romeo's life begins: he meets Juliet.
Introducing Juliet
Juliet says, "Hey, it's Romeo, you nearly gave me a heart attack"
He's underneath the window, she's singing, "Hey, la, my boyfriend's back
You shouldn't come around here singing up at people like that
Anyway, what you gonna do about it?"
Life becomes more complicated for Romeo now that Juliet is in his life. It is their first real relationship, and they have much to learn. We start simple. Let $J$ denote Juliet's feelings for Romeo, and let $R$ denote Romeo's feelings for Juliet. We can extend our single linear differential equation from above to a system of two linear differential equations:
Using the results from above, the solutions to the two differential equations are:
where $R(t)$ and $J(t)$ give the trajectories of love for Romeo and Juliet, respectively, and $J_0$ is Juliet's initial feeling towards Romeo at $t = 0$. In contrast to the one-dimensional phase diagram from above, we now have a two-dimensional picture which is known as a vector field.
Analogously to the case of a single differential equation, $a < 0$ and $d < 0$ imply exponential decay for Romeo and Juliet's love, and $a > 0$ and $d > 0$ imply exponential growth. The left figure below visualizes decay: whatever the initial state of their love, it will crash into the origin of indifference. The figure on ther right visualizes growth: whatever the initial state, except for indifference, their feelings will grow exponentially and eventually consume them.
plot of chunk unnamed-chunk-4
This can result in happy, ever increasing love if they start out liking each other (top right quadrant), but can also result in an increasingly violent feud if they start out disliking each other (bottom left quadrant). For asymmetric starts, one of them will be hopelessly in love with the other, while the other's hate grows unboundedly. The fixed point (0, 0) is stable on the left, as any tiny perturbation will move the system towards it. In contrast, the fixed point on the right is unstable, as any ounce of love or hate, no matter how small, will make the system explode. One unfortunate subtlety arises, however: if Romeo loves Juliet, but Juliet is indifferent, then Juliet will forever stay indifferent even though Romeo's love grows without bound.
Another interesting case occurs when their affection is asymmetric, i.e., $a \neq d$. The figure below on the left shows one such case for negative parameters: we see that whatever feelings Juliet has for Romeo, they decay faster then the feelings Romeo has for Juliet. Moreover, since $(a, d) < 0$, the origin is stable. The figure on the right shows a more impactful asymmetry: Romeo's feelings decay ($a < 0$), but Juliet's increase ($d > 0$). Regardless of what the initial feelings of Romeo are, he will always end up in a state of indifference with respect to Juliet (all arrows point to the y-axis). Juliet, on the other hand, will go increasingly mad with love or hate, depending on her initial feelings — the exception being if she starts out with indifference ($J_0 = 0$): then she will stay indifferent. This type of fixed point is called a saddle point, which occurs if there is one vector along which the system is stable (here the x-axis) and one vector along which the system is unstable (here the y-axis).
plot of chunk unnamed-chunk-5
What happens if Romeo's feelings never change, i.e., $a = 0$? This is visualized as the figure on the left below: Romeo's feelings will always stay at the initial point. Juliet's feelings decrease ($d < 0$), so regardless of where she is, the system will end up at a stable fixed point on the x-axis. A similar situation occurs if Juliet's feelings never change, and Romeo's feelings decay ($a < 0$), which is visualized in the figure on the right: all points on the y-axis are stable fixed points. If instead the moving parties' feelings would increase instead of decay, the fixed points would be unstable. The most boring case is $a = 0$ and $d = 0$, because then every point on the plane is a fixed point: however the two lovers start, they will never change.
plot of chunk unnamed-chunk-6
Note that in all the love affairs described above, the feelings of Romeo and Juliet are actually independent of each other. They do not communicate with each other, and we all know that communication is key! In the next section, Romeo and Juliet's relationship matured and they start taking each other seriously. Formally, we couple the two love birds and analyze what types of love this can set free.
Coupled differential equations
In the previous section, we saw that the behaviour of the system was determined entirely by the values of $a$ and $d$ — depending on whether $a$ or $d$ were positive, negative, or zero, the system would either be stable or unstable along the $R$ or $J$ dimension. Incorporating communication complicates the system, but is ultimately for the better. To model the fact that Romeo and Juliet now respond to each other's feelings, we simply write:
or in matrix form:
The classification of such a system is more difficult. In the next section, we introduce one type of relationship between a matured Romeo and Juliet that will motivate a

The optical methods for flow visualization in wind tunnels provide an interesting means of analysis. In order to extend their use, in transonic and supersonic flows, it is necessary to obtain photographs and high-speed pictures and a quantitative interpretation must be possible.
Two types of utilized equipment are described.
One of them is an interferometer of the horizontal Mach type. The other, called "interferential schlieren" apparatus, is the result of the application of the interferential contrast methods developed by Françon and Nomarski at the Institut d'Optique in Paris. In this paper, we describe two optical setups, the first for an over-all study of the flow over a model, the second for a detailed analysis of a small region.
Photographs obtained with these devices can be seen. They show how interesting is the interferential schlieren apparatus which permits, in certain cases, a quantitative analysis as precise as that provided by separated beams interferometry, but with a simpler equipment which is easier to handle, less sensitive to external vibrations, and less expensive.

After using Ubuntu now for a while I am searching for a macro program like AutoHotkey. I found nothing on the net, so maybe you can help me out.
I used AutoHotkey for the following tasks / search for a macro program which can do the following:
- text replacement: I type br# and it gets replaced with best regards, Alex
- url opening: I mark a word and press a shortcut which opens my webbrowser with a specified URL like _URL_.org?search=%s where %s is the marked word.
- hotkey for direct access to folder: I press for example +1 and nautilus opens with eg. /media/backup/
- hotkey few folder: I press eg + and a new folder is created and highlighted for renaming (or a dialog is presented where I only have to type in the name)
- paste as plain text: Strip all special markups in a text (like copied from firefox) and paste it.
- get pixel color: Press a hotkey to copy the pixel-colour under the mouse pointer to the clipboard or display it.
Do you know such a program which can perform all or a part of these actions? Let me know!
Lifehacker has a nice article: Feature: Automate Repetitive Typing with Snippits. Snippits does not support all the wanted features, but helps a lot.

"Why are the Crabs Dirty?"
Please consider making a gift today to support our tanks, and our decorator crabs from the Salish Sea. Donate HERE!
"Why are the crabs dirty?" I heard behind me in the Marine Exhibit one day. Thrown off by the visitor's question, I turned around and my eyes focused on the crab they were pointing to in the wall tank. It all made sense when I saw the graceful decorator crab scuttling along among the abalone, away from the sides of the tank, almost as if it knew it had been found. I jumped into educator mode right away, and answered, "That's a great question."

The most wonderful aspect our Marine Exhibit is the chance to gain new knowledge about Salish Sea fish and invertebrates. When I first started at the Port Townsend Marine Science Center, I knew very little about specific species of crabs. Aside from what I had learned in my college invertebrate zoology class, I hadn't thought about them much. However, once I started feeding individual crabs, and interacting with them in tanks every day, they became one of my favorite animals in our Marine Exhibit. As a person who is recovering from a phobia of spiders and spider-adjacent creatures, it means a lot when I say that I think the way these arthropods walk around the tanks and move their little maxillipeds (mouth parts) is quite cute. I love inspiring others to see them the way I do now. So, when I explain how decorator crabs got their name, and see others' eyes light up with fascination, it is a truly fulfilling experience. I hope I can light your eyes up, too.
Decorator crabs consist of many different species, all belonging to part of the superfamily Majoidea, known as spider crabs. We have many spider crabs in our exhibit, but not all are decorators. The decorator crab in question was the graceful decorator, Oregonia gracilis, a naturally abundant Puget Sound species. If you can spot them, graceful decorator crabs can be found in the small wall tank, against the back wall of the Marine Exhibit. In our huge piling tank, we have another type of decorator crab, called the longhorn, Chorilia longipes, which is usually hanging out against the tank walls, looking at the passers-by. These crabs' natural ecosystem includes kelp forests and the intertidal zone, ranging from Alaska all the way down to Mexico, but they're particularly abundant in the Pacific Northwest. In nature and in our tanks, the decorators are covered in foreign material (hence their dirty appearance) and found behind rocks and kelp, hiding from predators like fish, sea otters, and octopus.

The decorator crab namesake refers to the way they adorn their bodies with all kinds of ornaments. The decorations include almost any materials found in their environment. The crab's hard outer shell, or exoskeleton, has tiny hooks all over called hooked setae. Hooked setae act as a sort of Velcro on which the crab can stick materials it picks up from its environment. Their adornments act as a camouflage, but also as a symbiotic, mutually beneficial relationship. The "materials" picked up by the crab can include some bryozoans, hydroids, algae, sponges, and small anemones. Invertebrates gain access to parts of the water column and food they wouldn't usually have access to by hitching a ride on the back of the crab. In turn, the crab gets an easy disguise, and when resources are limited, also an easy source of food. If a crab finds an accessory like chemically-defended plants or stinging anemones, the crab is even less likely to be predated upon. Larger crabs need fewer decorations because they can defend themselves, but they'll often still wind up with some hitchhikers on their backs.
The decorating doesn't really stop after covering the exoskeleton canvas; a crab is always working. Crabs' exoskeletons do not grow with them. As they outgrow their armor, they grow a new shell underneath the old, effectively forcing the old exoskeleton off. After disrobing, the crab will hide until its new exoskeleton hardens, and then the decorating process starts all over again. They often recycle old bits and pieces of material from their discarded shell (a great example of environmental stewardship!). In captivity, decorator crabs have been known to disrobe and grow a new shell when moved to a different tank and new environment, effectively creating a blank slate for its new camouflage masterpiece.

Our decorator crabs at PTMSC interact with guests and staff all the time. In nature, humans and decorator crabs have very little direct interaction, although there are some negative human impacts on their ecosystems. Surface runoff of oil, pesticides, sewage, and other chemicals can contribute to pollution of ocean ecosystems, truly making the crabs' environment "dirty." (Runoff pollution contributes to larger issues like ocean acidification.) As environmental stewards, we can all make eco-friendlier choices to reduce negative impact on the Salish Sea. The crabs might thank you for that.
Next time you visit our Marine Exhibit, I hope you take the time to search the tanks for our decorator crabs. I hope you experience the revelation that the rock you were staring at underneath the kelp, barnacles, and sponges is actually a crab, as it slowly crawls away to munch on some food or find some new artistic materials. I also hope you become so enamored that you sound just as silly as I do when I have one-sided conversations with them through the acrylic. While cleaning or feeding, I compliment them on their attention to detail in design. I like to think they appreciate the compliments on their labor, because much like an environmental steward, a crab's work is never done.

Determine the difference in age between your child and the adult.
Determine the difference in age, in months, between your child and the older individual or adult. If the contact is sexual and the age spread is sufficient under the law, your child's circumstance may be proper for law enforcement investigation and prosecution. For example, in Washington if your child is between the age of 14 and 16 and the older person is at least 48 months older, this is a sufficient age spread to support a charge of child molestation if sexual contact between the two has occurred and can be proven. If the contact has been criminal in nature, this will support a petition for an anti-harassment order (i.e., restraining order).
Identify the type of contact your child and the adult are having.
Even if there is not clear criminal activity, determine what the nature of the contact between your child and the adult actually is (this might not be easy). Do they meet, talk on the phone, email or all of the above? And what do they talk about and do? Is there drinking involved or are they associating at unsafe hours in unsafe places with unsafe people?
Document how the contact with the adult is negatively affecting your child.
Has your child had a change in behavior or performance? Has your child begun skipping school, have your child's grades been affected, has he or she been drinking or using drugs, or engaging in other risky or dangerous behavior? Has your child been harmed? Document what those changes are.
Petition for an Anti-Harassment Order Against the Adult
An anti-harassment order restrains an individual from contacting a protected person. In Washington, a parent may seek an antiharassment order to protect their minor child from a person over the age of 18 if it can be shown to the satisfaction of the court that contact between the minor child and the adult is detrimental to the welfare of the child and that the adult's course of conduct would cause a reasonable parent to fear for the wellbeing of their child.
Be Prepared for a Fight
Be prepared for the adult to fight the issuance of the order and, if an order issues, for your child to potentially disregard or undermine the order. In other words, the anti-harassment order may not be the end of the contact and you will have to have a plan for how you will deal with violations and how to manage your child's reactions and actions.

An information paper, released in September 2007, described revisions to Australia's national and international accounts to be implemented in 2009. These revisions result from the updating of the respective international standards - the System of National Accounts (SNA) and the Balance of Payments Manual (BPM). This information paper is one in a series that provides more detail about the most significant changes being made to Australia's national and international accounts.
This paper discusses the treatment of Workers' remittances. Workers' remittances are cash or in-kind transfers by resident households in one economy to households of other economies. A methodology has been developed to estimate Workers' remittances debits (i.e. transfers out of Australia). The new data series will commence from September quarter 1989 and will be included under Personal transfers in the Secondary Income Account of the Balance of Payments from the September quarter 2009 issue of Balance of Payments and International Investment Position, Australia (cat. no. 5302.0).
DEFINITION AND STANDARDS
Workers' remittances are current transfers made by employees to residents of another economy. For many economies, Workers' remittances can represent a sizeable and stable source of funds that can exceed official aid or financial inflows from foreign direct investment. Workers' remittances is of considerable interest to economists and analysts because it can have a significant impact on poverty reduction and / or can finance economic growth in receiving economies.
The definition of Workers' remittances has not changed between the BPM 5th edition (BPM5) and the BPM 6th edition (BPM6), although in BPM6 Workers' remittances are included as a supplementary item under the Personal transfers category. Relevant extracts from BPM5 and BPM6 follow.
BPM5, paragraph 302 - Workers' remittances
Workers' remittances cover current transfers by migrants who are employed in their new economies and considered residents there. (A migrant is a person who comes to an economy and stays, or is expected to stay, for a year or more.) Workers' remittances often occur between related persons. Persons who work for and stay in new economies for less than a year are considered non residents; their transactions are appropriate mainly to compensation of employees. Workers' remittances are not currently estimated in Australia's Balance of Payments due to the difficulty in collecting or estimating this data.
BPM6, paragraphs 12.47 to 12.50 - Personal Transfers (includes Workers' remittances)
Personal transfers consist of all current transfers in cash or in kind made or received by resident households to or from non-resident households. Personal transfers thus include all current transfers between resident and non-resident individuals, independently of:
(a) the source of income of the sender (irrespective of whether the sender receives income from labour, entrepreneurial or property income, social benefits, and any other types of transfers; or disposes assets); and
(b) the relationship between the households (irrespective of whether they are related or unrelated individuals).
By convention, current transfers between households with regard to lotteries and other gambling are included under personal transfers.
Workers' remittances are current transfers made by employees to residents of another economy. They are included as a supplementary item.
The connection to the residence status of the person concerned is important in determining whether a personal transfer is involved. In the case of workers, personal transfers include only those transfers abroad made by workers who are residents of the economy in which they are employed.
Funds sent abroad by individuals who are resident in the economy in which they are employed, self-employed, or operating a business, for the purpose of making a deposit in his or her own account with a bank located abroad represent a financial investment, which is recorded in the financial account, rather than as a personal transfer. But, any withdrawals to provide resources to a relative or another person (without a quid pro quo) should be recorded as a personal transfer.
In BPM5 Workers' remittances is recorded in its own category and is a sub-component of 'Current transfers'. The current presentation is shown in table 23 of Balance of Payments and International Investment Position, Australia (cat. no. 5302.0). BPM6 includes Workers' remittances under a new category termed 'Personal transfers'. Personal transfers is a sub-component of the 'Secondary Income'. In BPM6 Workers' remittances is a supplementary item meaning that each country can decide if this item should be recorded separately.
Along with other changes to the international accounts, the revised treatment of Worker's remittances will be implemented in the September quarter 2009 issue of Balance of Payments and International Investment Position, Australia (cat. no. 5302.0). Workers' remittances will be presented as a supplementary item in the 'Secondary income' table. The new classification and estimation methodology will also be applied in the 2008-09 issue of Australian System of National Accounts (cat. no. 5204.0) and the September quarter 2009 issue of Australian National Accounts: National Income, Expenditure and Product (cat. no. 5206.0).
WORKERS' REMITTANCES CREDITS (INFLOWS)
It is not currently possible to estimate the value of Workers' remittances credits (inflows) as there is no information available regarding the amounts expatriate Australians remit back to Australia. It is considered unlikely that Australia receives significant amounts of remittances. Therefore, both the Personal transfers credits item and the Workers' remittances credits supplementary item will be recorded as not available (n.a.).
NEW METHODOLOGY AND DATA SOURCES FOR WORKERS' REMITTANCES DEBITS (OUTFLOWS)
The estimate for Workers' remittances debits (outflows) is derived using the following formula:
Total Workers remittances = population of remitters x average amount remitted, where
- Population of remitters = foreign born population x percentage remitting to another economy
- Average remitted = average income of foreign born employees x percentage of income remitted to another economy
ESTIMATES OF WORKERS' REMITTANCES DEBITS AND IMPACT ON THE CURRENT ACCOUNT
- The data sources for the above components are:
- Estimates of foreign born employees (i.e. foreign born population) and average weekly earnings (i.e. average income) of foreign born employees aged between 15 and 54 years are derived from Employee Earnings, Benefits and Trade Union Membership, Australia (cat. no. 6310.0).
- The percentage of foreign born employees remitting to another economy and the percentage of their income remitted to another economy are obtained from the 2004 report on the Second Longitudinal Survey of Immigrants in Australia (LSIA2), The Changing Settlement Experience of New Migrants, prepared by the National Institute of Labour Studies, Flinders University.
Secondary income (Current transfers) debits will increase by $676 million in 2006-07 due to the incorporation of an estimate of Workers' remittances. This is likely to increase current account debits by between 0.2% and 0.3%.
Table 1: Estimates of Workers' remittances debits and impact on the current account 1996-97 to 2006-07
Workers' remittances debits
Current account debits
Estimated impact on
Current account debits
Over the past ten years the value of Workers' remittances has increased from $414 million to $676 million, an average increase of 5% per year. The percentage increase was lower in 2000-01 and 2003-04 due to falls in the employed foreign born population.
Estimates for Workers' remittances debits have been compiled from September quarter 1989 onwards. Estimates could not be compiled for earlier periods because estimates of the average weekly earnings of foreign born persons are not available prior to 1989-90. As a result, both the Personal transfers debits item and the Workers' remittances debits supplementary item will be recorded as not available (n.a.) prior to September quarter 1989.
Workers' remittances are one part of Personal transfers albeit usually the most significant. Due to the lack of information currently available on other Personal transfers, Workers' remittances debits and Personal transfer debits will have the same value.

1 GeoCam Memo Web
1.1 About
The GeoCam Project helps people better understand and respond to disasters. GeoCam consists of a GPS-enabled camera (or cell phone) and a web app for sharing geotagged photos and other geospatial data.
GeoCam Memo is a scribing and note-taking application intended for use by search team members as they canvas the scene of a disaster. Notes can be recorded using text or audio and various forms of attachments (including but not limited to images) can be attached for transmission to a central server. All messages can be geotagged and categorized before saving to provide proper context when analyzing them via a web interface at a later time.
GeoCam Talk is a communication application intended to aid in communication during a search mission. Members can send text and audio messages to any subset of their team members while on the field from their mobile devices. All messages are sent through a central server which catalogs them for later analysis. Just as in Memo, all messages are geotagged to provide instant awareness of team member location.
This is the web application for both GeoCam Memo and GeoCam Talk

Shaping the Dialogue
The primary purpose of an ACCJC-accredited institution is to foster learning in its students. An effective institution ensures that its resources and processes support student learning, continuously assesses that learning, and pursues institutional excellence and improvement. An effective institution maintains an ongoing, selfreflective dialogue about its quality and improvement.
An institution-wide dialogue must be at the heart of the self-evaluation process for the college community to gain a comprehensive perspective of the institution. Although the standards are presented in four parts, they work together to facilitate this dialogue on the institution's effectiveness and on ways in which it may improve. The self study provides the Commission with the institution's assessment of itself as a whole.
The institutional mission provides the impetus for achieving student learning and other goals that the institution endeavors to accomplish. The institution provides the means for students to learn, assesses how well learning is occurring, and strives to improve that learning through ongoing, systematic, and integrated planning (Standard I). Instructional programs, student support services, and library and learning support services facilitate the achievement of the institution's stated student learning outcomes (Standard II). Human, physical, technology, and financial resources enable these programs and services to function and improve (Standard III). Ethical and effective leadership throughout the organization guides the accomplishment of the mission and supports institutional effectiveness and improvement (Standard IV).
A collegewide dialogue that integrates the elements of the Standards provides the complete view of the institution that is needed to verify integrity and to promote quality and improvement.

Cable test equipment
High voltage cable testing
High voltage cable testing
Off shore cable fault finding and diagnosis
Withstand tests may include a DC withstand or hi-pot (though not to be used on XLPE cables); a line frequency AC hi-pota 0.1 Hz AC VLF hi-pot; or a damped AC (DAC), where electrical stresses are created at a frequency ranging from around 50 Hz to several hundred Hertz depending on the test object capacitance.
High voltage testing will also check for local faults. For example, an XLPE cable will tend to turn critical water trees into electrical trees and subsequently cause a failure. Having been subjected to adverse impulses/surges during its service lifetime, testing will be necessary to find and avert imminent in-service failures in the future.
If cable testing highlights a subsequent failure, this indicates that the cable is already in a highly compromised condition. Company staff should be prepared at this stage to make any necessary repairs to the cable at the position indicated by previous tests. After repair, the cable will have a withstand test again until it passes the required voltage of the test.

Definition and meaning of the idiom "foot the bill"
What does the idiom "foot the bill" mean? How can I use the idiom "foot the bill in a full sentence?"
You may even encounter a native speaker using the idiom "to foot the bill." This saying, counter-intuitively, has nothing to do with feet. By saying this, the speaker is stating that they will pay the bill.
For example, "William often dines with us, but he never foots the bill" which simply means, he never pays.
Moreover, the person who foots the bill only means he/ she pays the entire bill. The idiom is most often used with dining but can be applied to anything.
Examples of the idiom foot the bill
- Riley footed the bill as he had gotten a raise.
- Fran always has an excuse when it comes time to foot the bill.
- His father footed the bill for his college education.
- The company foots the bill for all business lunches.
- Ryo hates taking favors, hence always foots the bill when he goes for lunch with his friends.
Q1: Try and make your own sentence using the idiom "foot the bill".
Q2: Who foots the bill usually among your friends?
Q3: Should the man of the woman foot the bill on a date? Why?

Applet Message
An applet message is a free-flowing text control which presents a mix of hard-coded, static text strings and dynamic data from the Siebel database, filled in at run time. An applet message is presented as a continuous, wrapped line of text. Applet messages are similar to the personalization text which appears on home pages. You can use applet messages to provide instructions to the end user performing the task. For example, in the Siebel Call Center application, an applet message may represent a block of text to be read by a customer service representative (the end user), when addressing a customer.
You specify the static text at design time. The dynamic data is derived from business component fields and, at run time, it becomes part of the applet message the end user sees while moving through the task.
NOTE: The format of the text in the applet message is not editable.
An applet message, as a user interface control, is statically positioned within the task applet. It differs from other control types (such as Text or Field) by always displaying its content as read-only, and not inside a box or border in the user interface.
Figure 3 shows an example of an applet message. In this example, the values for status, account, and the name and number of the agreement are dynamic.

Use of Hierarchical Stepwise Optimization for the Segmentation of Cloud Features
COMPUTER SCIENCES CORP MONTEREY CA
Pagination or Media Count:
The Hierarchical Stepwise Optimization algorithm of Beaulieu and Goldberg 1989 is applied to the segmentation of satellite images into meaningful, large scale cloud features. GOES-W visible imagery is used. Several different forms of the cost function are explored in an attempt to improve the segmentation of Nov. 15, 1983 case. A new cost function is shown to result in a superior segmentation. Both HSWO versions are tested on six additional cases. A modification to the HSWO approach is suggested for further research.


10 Objects. These 10 triangle objects have the same properties and behaviors (but the specific side length values are different), you can change them Abstraction is a type, called triangle type. In C++, this type can be defined as "class". This Ten triangles are objects belonging to the same "class". Just as 10 Chinese belong to the "Chinese" category, 10 Americans Belongs to the "American" category. A class is an abstraction of an object, and an object is a special case of a class, or a concrete manifestation of a class form.
Inheritance and Reuse in Object-Oriented Programming:
If a car manufacturer wants to produce a new type of car, it will generally not design it all from scratch.
Based on a certain model of car, some new functions are added to develop a new model of car. This is to improve health Common methods of productivity. If you have already established a "class" named A in software development, and you want to create another named B "Class", while the latter is basically the same as the former, except that some attributes and behaviors are added on the basis of the former. Then design a new class from scratch, and only need to add some new content on the basis of class A. This is the object-oriented process Inheritance mechanism in order design. Using inheritance can simplify the steps of programming. For example: if everyone has Having fully understood the characteristics of horses, now I want to describe the characteristics of "white horses". Obviously, it is not necessary to introduce what a horse is from the beginning, but just say Clearly, "a white horse is a white horse". This simplifies people's The knowledge and description of things simplifies work procedures. "White Horse" inherits the basic characteristics of "horse" and adds new characteristics (color). "Horse" is the parent category, or called the base The class "white horse" is derived from "horse" and is called a subclass or derived class. If you still want to define "white stallion", just say Ming "a white stallion is a male white horse". "White Stallion" is a subtype or derivative of "White Horse".
 C++ provides an inheritance mechanism, and the inheritance method can easily use an existing class to create a new This can reuse part or even most of the existing software, which greatly saves programming workload. This is often The idea of "software reusability" can not only use the classes you have built in the past, but also You can use the classes used by others or the classes stored in the class library, and these classes can be used after proper processing, which greatly shortens The software development cycle is of great significance to the development of large-scale software. 5. Polymorphism If there are several objects that are similar but not exactly the same, sometimes people require that when sending the same message to them, it They reacted differently and performed different operations. This situation is polymorphism. For example, A, B, C 3 The classes are all in the second grade. They have basically the same attributes and behaviors. When they hear the class bell at the same time, they will go separately Enter 3 classrooms without going to the same classroom. Similarly, if there are two armies, when you hear a kind of The sound of the trumpet, due to different prior agreements, the A army may carry out an offensive, while the B army may prepare to start a meal. Another example, in Windows
In the environment, double-click a file object with the mouse (this is to send a message to the object), if the object is An executable file, this program will be executed, if the object is a text file, a text editor will be launched and opened The document. There are many situations. In C++, the so-called polymorphism (polymorphism) refers to: related different classes produced by inheritance, which Objects will respond differently to the same message. Polymorphism is an important feature of object-oriented programming, which can increase the flexibility of the program.
The role of classes and objects in object-oriented programming
"Class" is a very important concept in C++, it is the basis of object-oriented programming. C++ to C The most important thing for improvement is to add a type of "class". So C++ was originally called "C with classes". class It is a common feature of all object-oriented languages, and all object-oriented languages provide this type. If one Computer language does not contain classes, it cannot be called an object-oriented language. A C++ program of a certain scale is Composed of many categories. It can be said that classes are the soul of C++. If you don't really master classes, you can't really control them.
C++ supports process-oriented programming, as well as object-based and object-oriented programming. From this chapter to Chapter 4 introduces object-based programming. Including the concepts of classes and objects, the mechanisms and declarations of classes, and the definition of class objects And use etc. This is the basis of object-oriented programming. due to Object-based is based on class. Unlike process-oriented programs, object-based programs are based on classes and objects
Basically, the operation of the program is carried out around the object. On this basis, using inheritance and polymorphism, it becomes Object programming (sometimes not subdivided based on object programming and object-oriented programming, and the two are collectively referred to as Object-oriented programming). Object-based programming faces each object. All data belong to different objects. Face to The data in the process program is public or shared. If there are variables a, b, c, they can be used by different functions.
Call, which means that these data are lack of protection. The cross-use of data can easily lead to program errors. And real In fact, each set of data in the program is prepared for a certain operation, that is, a set of data is related to a set of operations. For the corresponding. Therefore, people imagine that related data and operations are put together to form a whole, which is relatively separated from the outside world. Separated. This is the object in object-oriented programming. In process-oriented structured programming, people often use this formula to express the program:
Program = Algorithm + Data Structure The algorithm and data structure are independent and designed separately, and the process-oriented programming is based on the algorithm. of. In practice, people gradually realize that algorithms and data structures are closely related to each other and inseparable. The method corresponds to a set of data structures, and it is not advisable to advocate that one algorithm corresponds to multiple sets of data structures, and one set of data structures corresponds to multiple data structures.
Algorithms. Object-based and object-oriented programming is to encapsulate an algorithm and a set of data structures in an object. Therefore, a new concept was formed:
Object = algorithm + data structure Program = (Object+Object+Object+…)+Message Or expressed as Program = Object S+ Message "Object" means "multiple objects". The function of the message is to control the object. The key to programming is design Good for each object, and determine the commands issued to these objects, so that each object completes the corresponding operation.

This children's book about the night the Titanic sunk is an evocative new spin on the disaster.
The sinking of the Titanic is probably the world's most famous maritime disaster, and 2012 not only marks 100 years since the ship hit the iceberg, but also 100 years of books, journals, films and television programmes discussing every inch of the ship from every possible angle. The challenge for any author wishing to contribute to this ever expanding library of works is to add something new and engage an audience that inevitably already knows how the story ends.
Keeping broadly within the confines of documented events Allan Wolf's novel, written in verse, gives a fictional voice to many of those people who were on board the ship based on the available historical evidence. From millionaires and socialites to refugees and immigrants, from the captain of the ship to the stoker in the boiler room, Wolf engages us with the individual stories that could all too easily be lost in the icy waters of the Atlantic.
There will be many books published on the Titanic this year, but whilst some will appeal solely to the Titanic devotee, The Watch That Ends the Night is an intelligent account for older children, but deserves to be enjoyed by a far wider audience. Not only do the different voices combine to provide a rich picture of life on the ship, and of the time, but the extensive back material will provide plenty of further information for those who discover the continuing appeal of the Titanic.

You have to admit there's at least a little resemblance between the ring-lined cross-section of a tree and an LP. So why shouldn't a tree's rings elicit beautiful music the way a record's can?
That might well have been the inspiration for Bartholomaus Traubeck's Years project, a record player that can read the rings of a tree and translate them into lovely piano melodies.
According to the Years Web site, "A tree's year rings are analyzed for their strength, thickness and rate of growth. This data serves as basis for a generative process that outputs piano music. It is mapped to a scale which is again defined by the overall appearance of the wood (ranging from dark to light and from strong texture to light texture). The foundation for the music is certainly found in the defined ruleset of programming and hardware setup, but the data acquired from every tree interprets this ruleset very differently."
One wonders whether different families of trees produce varying kinds of music. For example, does a willow generate more soulful ballads? Or would Mozart come from an old growth redwood? Poplars grow fast, so could they be used for upbeat tunes?
It's a terrific idea, and I'd love to see this in person. But absent that, next time I go hiking into the forest, I'm just going to have to imagine what the many trees I'm walking by would be singing if they got the chance.
