Cloud-SDR: A Tool for Remotely Accessing SDR's like the RTL-SDR and Airspy
Cloud-SDR is a new tool currently in beta testing which enables remote streaming access of SDR receivers, such as the RTL-SDR and Airspy. In a way it is similar to rtl_tcp in that it allows IQ samples to be streamed over the network, however Cloud-SDR appears to be a much more developed solution that can support more SDR's and has many more features, as well as better performance. Cloud-SDR is not free, and during these beta stages of release the pricing does not appear to be public. However they have licences for personal/hobbyist use, which we assume will be reasonably priced.
In this interesting post they describe various solutions for remote SDR access, and show why their Cloud-SDR solution is useful.
They describe their software in the following blurb:
Cloud-SDR can collect real-time IQ complex samples from an SDR hardware device connected on one machine, stream the samples to a second machine for demodulation or analysis, then send the resulting stream to third machine for storage.
In standalone mode, Cloud-SDR can execute signal processing tasks described with embedded JavaScript DSP engine.
Because network bandwidth is limited compared to SDR receiving bandwidth, the core concept of Cloud-SDR is to move the processing along the cloud to where it is required or possible : the DSP chain is divided in sub-tasks that are spread between computers interconnected through Internet.
For example a "signal scanner" application can be programmed with a script and stored on the SDR server for execution. Only found signals will threshold stream transmission through the TCP/IP network. Remote Client will only receive the IQ stream if a signal is detected by the DSP task. In "cloud mode", the same script can be broadcasted to several SDR nodes located at different places, enabling parrallel signal search.
Server software SDRNode receives IQ streams from the different SDR hardwares, extracts the different bands, processes them and transmits the RF data using compression algorithms to limit TCP/IP network bandwidth.
Currently the hardware supported includes:
 - RTL SDR dongles
 - Perseus SDR
 - BladeRF x40 or x120
 - HackRF
 - AirSpy
 - SDRPlay (under work)
 - USRP UHD (Pro version only)
 - LimeSDR (Pro version only)
On their site they have some tutorials uploaded already. One tutorial shows how to remotely listen to airport radio with a remote Airspy, and one shows how to set up a dual-RTLSDR remote access system. This allows two RTL-SDR's to be used together, with one streaming directly from the antenna, and the second streaming via an upconverter.

There are also several examples of the Cloud-SDR in action over on the authors YouTube channel.
Creating a wireless RTL-SDR server with a small OpenWRT WiFi Router
Over on his blog yo2ldk has been experimenting with creating a wireless RTL-SDR server by using a mini OpenWRT based WiFi router (page in Romanian, use Google Translate for English). The router he uses is the GL iNet 802.11n 150Mbps router, which is a mini WiFi router that only costs $27 USD and is about the same size as an RTL-SDR dongle. It is mainly intended for use with IoT devices, but it runs the Linux based OpenWRT firmware and has enough processing power and WiFi bandwidth to run an rtl_tcp server streaming at 2MSPS with no lag.
With an RTL-SDR connected and the router running rtl_tcp, the router can be placed anywhere there is power (yo2ldk uses a portable battery pack) to create a remote radio receiver with absolutely no coax cable losses. It's WiFi range could be extended over long distances by using a directional Yagi antenna.
Using routers instead of mini computers like the recently released Raspberry Pi 3 may be a good option because they are very small, usually much cheaper, maybe be more power efficient, and may work better at transmitting the large amounts of data rtl_tcp requires.
In the future yo2ldk hopes to install everything into a shielded metal case, add an upconverter and also a solar panel for remote power.

We note that if you have an old Android phone, then this could also potentially be used as a remote RTL-SDR server. To create an android RTL-SDR server simply download the Martin Marinov Android RTL2832U Driver from the Google play store. Find the IP address of your Android phone by going to Settings -> About Device -> Status -> IP Address. Then open the RTL2832U driver app and click on "Enable advanced mode (for debug & stream to PC)". Initially the rtl_tcp string will have the code "-a", simply change this to the IP address of your Android phone, for example "-a" and then click Start stream. Now on a remote PC connected to the same network open SDR# go to RTL-SDR (TCP) and type in the IP address of the phone and use the port number 14423. Click the play button and you should now be streaming your RTL-SDR data over WiFi.
New Raspberry PI Remote RTL-SDR GUI Software: MNM4SDR
Recently RTL-SDR.com reader Slaven Krilic wrote in to use to announce his project called MNM4SDR which stands for Monitoring Network Manager for RTL-SDR. The software allows you to set up a remote Raspberry PI embedded computer with an RTL-SDR dongle attached and access it remotely through a Windows PC GUI.
Unlike other server software such as rtl_tcp, raw IQ data is not sent over the network. Instead audio is first compressed in lossless FLAC or OGG formats. This allows you to use much slower network or internet connections. The software also allows you to collected RF scans over a large bandwidth in a similar way to rtl_power.
The software works over an SSH connection and requires that you have RTL-SDR and VLC set up on your Rasperry Pi first.

OpenWebRX: A Multi-User RTL-SDR Receiver with Web Interface
From Reddit we've learned of a new web based SDR receiver software for the RTL-SDR called OpenWebRX. This python based software allows you to run a web server that allows multiple users to connect to an RTL-SDR and listen to it through a web interface. The web interface also allows the RTL-SDR frequency and mode settings to be controlled. The software appears to still be in beta, so it may have some bugs.
The author has also written his BSc. thesis on this software and it is available for reading here. The thesis describes his software design and implementation as well as some SDR theory and may be useful to anyone wishing to implement similar SDR software.

The feature in question is the notation for anonymous functions: the underscore. It seems that in Scala
_(just underscore) is the abbreviation for the identity function
f => f
((_:Integer).intValue)is the abbreviation for
((x:Integer) => x.intValue)
(x => Integer.valueOf(x))
anObject.method(_ ~ xxx ~ yyy)is the abbreviation of
anObject.method(f => f ~ xxx ~ yyy)
Let us briefly review the Montagovian semantics of natural languages. A declarative sentence such as
(1) John saw Mary.denotes a proposition, which is true just in case a person denoted by the name John indeed saw a person denoted by the name Mary. We can write the proposition as a formula in the Simple Theory of Types (STT):
(2) see mary johnwhere
johnare individuals (of the type
e) who go by the names Mary and John, respectively;
see, the meaning of the transitive verb 'see', is a function symbol of the type
e -> e -> t. Here
tis the type of propositions. (In Church's STT, the type
iand the type
o. For some reason, Montague renamed the types).
Let us consider a sentence
(3) It was Mary who John saw.or, simpler
(4) Mary, John saw.We'd like to write a logical formula representing the meaning of (4). We would like our semantics to be compositional: the meaning of a sentence should be composed from the meaning of its parts. Thus, we have to determine the meaning of the part ''John saw.'' A transitive verb requires two arguments: first an object, then a subject. The phrase ''John saw'' seems to be missing an object. To handle such phrases -- verb phrases (VP) missing a component -- linguists have introduced a so-called 'trace', often written as an underscore. The trace is assumed silent (not pronounced). Thus the sentence (4) is to be written
(4') Mary, John saw _.
The sentences with traces are common. Examples include raised questions and relative clauses:
(5) Who did John see _. (6) I know whom John saw _. (7) The person John saw _ ran away.Some theories of quantifier scope use trace to explain how a quantifier word such as 'someone' influences the meaning of -- 'takes scope over' -- the entire sentence. This so-called 'quantifier raising' posits that a sentence such as
Alice thinks someone left.should be analyzed as if it were
someone (Alice thinks _ left).
It seems like a good idea to take the meaning of ''John saw _'' to be
(8) fun x -> see x johnThe meaning of (4') then can be composed from the meaning of its components as
(9) (fun x -> see x john) maryA beta-reduction then gives us (2). Chomsky might say that the transformation from the surface form of the utterance (4') to the logical, hidden form (2) involves a movement of Mary into the position occupied by the trace.
We now face the question of the meaning of trace and using that meaning to compositionally derive (8) from ''John saw _.'' We observe that ''John saw _'' looks like ''John saw Mary'' with ''Mary'' taken out. Therefore, ''John saw _'' is a context, a term with a hole; trace denotes the hole. Continuations are the meanings of contexts. Since ''John saw _'' is a sub-phrase of the larger sentence (4'), our context is partial -- or delimited, -- with a delimited continuation as its meaning. A delimited continuation can be captured by a delimited control operator
reset (see (shift (fun k -> k)) john)indeed reduces to
fun x -> see x johnTherefore, we may take the meaning of trace to be
(shift (fun (k -> k)). To type that expression, we need shift with the answer-type modification.
The topic of delimited control in natural languages is discussed in great detail by Chung-chieh Shan in a book chapter ''Linguistic Side Effects.'' He analyzes more complex sentences, for example:
(10) Who _ saw his mother?
A pronoun could be treated like a trace. The sentence (10) hence exhibits three components with side-effect: the question word, the trace, and the pronoun. Chung-chieh Shan explains their interactions.
Coming back to Scala, it seems that
_ is the trace and the expression boundary is a reset.
It is remarkable that natural and programming languages can inform each other. Consciously or not, Scala seems like the best example of such mutual development.
We describe the relationship between the surface form of a sentence
and its meaning as two non-trivial but mechanical interpretations of
the same (hidden) abstract form. Our approach, in the tradition of
abstract categorial grammar (ACG), deals with several languages: The
A is the language of abstract form; the language
I is the
language in which we write a compositional interpreter of
produces a term in a language
T. The language
A is simply-typed
lambda-calculus with constants.
A syntactic interpretation
Isyn gives a surface form for a sentence
Tsyn is a set of strings or utterances. This
interpretation is responsible for word order, case marking,
subject-verb agreement, etc. Therefore,
A is abstracted from these
A can be determined from
Tsyn by parsing. If
the abstract language is simple -- that is, its constants have types
of low order -- parsing is tractable. This is the case for our ACGs.
A semantic interpretation
Isem computes the meaning of
A as a logical
Tsem is thus the language of predicate logic.
deals with quantifiers, pronouns, question words and
their interactions. Our
Isem interpreter is non-trivial:
it may fail. Although we may parse a sentence to an
abstract form, we may fail to compute any meaning for it, if the
sentence just 'doesn't make sense'. Our
Isem is not a regular
lambda-calculus: it expresses computational effects such as mutation
and continuations, and it is not normalizable. The interpreter
Isem :: A -> Tsem may be represented as a composition of two
I1 :: A -> T1 and
I2 :: T1 -> Tsem for some
T1. A complex transformation may be assembled
from simpler steps.
The computational effects let us express in a modular fashion the interaction of a phrase with its context, and analyze different scopes of quantifiers and scoping islands.
Abstract Categorial Grammar (ACG) is a grammar formalism based on typed lambda-calculus. The syntactic side of ACGs -- parsing algorithms, generative power and other formal-language--theoretical properties -- is under active investigation. ACGs can also elegantly model syntax-semantics interface and compute truth conditions. This semantic side of ACGs has received much less attention.
We describe a generalization of ACGs that lets us give the standard dynamic-logic account of anaphora and analyze quantifier strength, quantifier ambiguity and scope islands. Most of these ACG analyses have not been possible before; prior ACG analyzes of quantifier ambiguity required type lifting, hence higher-order ACGs with very high parsing complexity.
Our generalization to ACG affects only the mapping from abstract language to semantics. We retain all ACG benefits of parsing from the surface form. By avoiding type lifting we keep the order of the abstract signature low, so that parsing remains tractable.
The generalization relies on 'applicative functors', which extend function applications. The fact that applicative functors compose lets us take the full advantage of modularity and compositionality of ACGs. We assemble the semantic mapping from separate, independently developed components responsible for a single phenomenon such as anaphora, coordination, universal or indefinite operator. We have implemented the generalized ACGs in a 'semantic calculator', which is the ordinary Haskell interpreter. The calculator lets us write grammar derivations in a linguist-readable form and see their yields, types and truth conditions. We easily extend fragments with more lexical items and operators, and experiment with different semantic-mapping assemblies.
The definition of the Abstract language and its mapping to the surface 'syntax'
We define Abstract for a small fragment, later extended with sentence conjunction, anaphora and quantifiers.
The language of meaning: First-order predicate logic
We also lift the logic through an applicative.
The syntax-semantic interface
We demonstrate the interface for the small fragment, and its modular extension for sentence conjunction, dynamic logic, and two levels of quantification. We illustrate the successive, multi-stage re-writing of Abstract into the meaning.
Standard CPS and State Applicatives, which could have been defined in the standard applicative library
Abstract Categorial Grammars (ACG) represent syntax-semantic interface by regarding the surface and logical forms as two different interpretations of an abstract form. All three forms are represented in ACG uniformly, as closed (normal) terms in typed linear lambda-calculus over a signature defining base types, constants and the type assignments to the constants. An interpretation of one, abstract calculus, in another, object calculus is formalized in a lexicon, which is a homomorphic, typing preserving map of constants and types of the abstract calculus into terms and types of the object calculus.
Strictly speaking, the mapping of an abstract term
tA to an object term includes not only the mapping of constants of
tA as specified by the lexicon, but also the normalization

from Dive into HTML5: Cache Manifest: Fallback section
/ /offline.html
i dont understand from the URL given what this block of code exactly does. does the fallback section mean when anything is not found, show the offline.html page
then network: * all resources will be cached? it says also
It uses common CSS, JavaScript, and images on each page. Each of these resources would need to be listed explicitly in the CACHE
this seems to conflict to network: * where it seems to say cache everything?

There are three types of headings in a cache manifest, CACHE, NETWORK and FALLBACK. Anything that is not under a heading is implicitly set under CACHE. An explanation of each section:
CACHE: Files under this heading will be cached.
NETWORK: Files under this heading require an internet connection and so will be NOT be cached.
FALLBACK: Files matched by patterns under this heading (Such as the pattern "/", which matches all files) and have not been cached, will have a fallback file shown instead.
With regards to the block of code from Dive into HTML 5, there is an explanation of the "NETWORK: *" part just under it:
It means that, while you're browsing this hypothetical offline-enabled Wikipedia online, your browser will fetch images and videos and other embedded resources normally, even if they are on a different domain. (This is common in large websites, even if they aren't part of an offline web application. HTML pages are generated and served locally, while images and videos are served from a CDN on another domain.) Without this wildcard flag, our hypothetical offline-enabled Wikipedia would behave strangely when you were online — specifically, it wouldn't load any externally-hosted images or videos!
The following quote:
means that you must include all necessary CSS, Javascript and image files in the manifest under the CACHE heading. It does not conflict with 'NETWORK: *' because the NETWORK heading does NOT mean 'cache everything'. It actually means the opposite: that everything under the NETWORK heading requires an internet connection and should not be cached.

I have found out more useful stuff about FALLBACK:
After a bit of experimenting, I tried various things including whether files in FALLBACK: should appear in the CACHE or NETWORK sections at all. The answer seems to be no.
As an example... FALLBACK: sign-up-portrait.png offline-portrait-1.png sign-up-landscape.png offline-landscape-1.png
I specified this in one of my micro sites recently. The intention is to show the sign-uppng files when online and the offlinepng files when offline. This works well. In particular the files on the left side of each line are implicitly as if they were in the NETWORK section, the site will always try to get them online. They must not be added to the NETWORK section as well, otherwise it seems to override what's in FALLBACK. Plus, happily, the files on the right are implicitly as if added in the CACHE: section so even if they are not used at first, they are cached on first load without having to explicitly add them to CACHE: although you can add them there too if you want. It makes no difference.
For this configuration, looking at the webserver logs, I see that each time the page is refreshed, apache logs a 304 against the manifest file and against the sign-uppng file that's required for that version of the page (there's a CSS media selector determining which, based on page size). So it's correctly always checking for the sign-uppng files as well as the usual manifest checking, which is exactly what I want.
For the sake of being thorough, I tried to see if the root file needs to be in the CACHE: section too. It turns out it doesn't! If your top level file is index.html and it has the manifest file specified in its html tag then the manifest file need not contain index.html anywhere, it's implicitly cached.
I am curious how far the app cache can extend. Can you include other html files that are linked to or in iframes? Or do those all need to have their own manifest files that are separate? Anyone care to comment?
A side comment about format, don't make the mistake I did, which is to put in... NETWORK file1.js
Missing the colon causes it to totally break, thinking that NETWORK is a resource in its own right.
It must be... NETWORK: file1.js

Thanks for experimenting and coming back to leave the feedback!! I was just about to get started doing the same thing because I didn't understand how the stuff in the Fallback would be cached and if it wasn't explicitly specified somewhere – Kirn Feb 18 '13 at 4:44

If you have just had a new baby, you must register the birth. This applies to all children born in the Netherlands. You must register the birth within 3 days in the municipality where they were born. The mother, father or the mother's female partner (duomoeder) can register the birth.
You must register the birth of a new baby within 3 days, not counting the day of the birth. For example, was your child born on a Monday? Then you must register the birth on Thursday at the latest.
If the third day falls on a Saturday, Sunday or public holiday, the deadline for registering the birth is extended until the next working day. If that means you have only 1 day to register the birth, you will be given an extra day, to ensure that there are always at least 2 days to register the birth.
Late birth registrations
If you are late registering the birth, then the Registrar of Births, Deaths, Marriages and Civil Partnerships (ambtenaar van de burgerlijke stand) will inform the public prosecutor (officier van justitie). You may then have to pay a fine.
A baby's birth can be registered by the mother, father or the mother's female partner.
If the mother, father or mother's female partner are not able to register the birth, then the birth can be registered by:
someone who was present at the birth;
the owner of the house in which the child was born;
an employee of the institution where the child was born, such as a hospital.
If none of these people are able to register the birth, the birth can be registered by or on behalf of the mayor of the municipality where the child was born, or where the child was found if they are a foundling.
You do not have to bring the baby with you when you register the birth.
If your baby was born in a vehicle, for example in a car, ambulance, train or aeroplane, you must register the birth at the place of arrival, i.e. the location where your baby leaves the vehicle. This applies if that location is in the Netherlands.
If your baby is born during an international flight or an international sea voyage and the location where you arrive is not in the Netherlands, there are 2 options:
- if the boat or aircraft is registered in the Netherlands, you must obtain a temporary birth certificate (geboorteakte) from the captain of the aircraft or boat.
- If the boat or aircraft is not registered in the Netherlands, you must obtain a birth certificate from the authorities in the local area.
When you arrive at your destination, you must obtain a temporary birth certificate at your place of arrival and send this as quickly as possible to the civil registrar in the municipality of Den Haag (The Hague).
Bring these documents with you when registering a birth at the municipality:
- A valid form of identification.
- An acknowledgement of parenthood (akte van erkenning) or declaration of surname choice (akte van erkenning of naamskeuze) if issued before the birth.
- A declaration of birth, issued by the hospital or midwife.
The civil registrar at the municipality will issue the birth certificate. This is written proof that you have registered the birth of your child.
The birth certificate contains the following information:
- the baby's details, for example: name, date of birth, place of birth and time of birth;
- the personal details of the parent(s).
The birth certificate is the official proof of birth, and also proves who the child's parents are.
This is how it works in your (future) place of residence
Municipality of Noardeast-Fryslân: Registering a birth
Inform the municipality directly of the birth of your child. You can do so:
- At the service desk
You can book an appointment for this, for more information contact us at _EMAIL_

PINETOP, Ariz. — Biologists from multiple agencies working on the Mexican Wolf Interagency Field Team (IFT) have been surveying Mexican wolf end-of-year population numbers since Nov. 1, 2021. Those surveys are expected to continue through Feb. 2.
Population numbers are essential for the Mexican wolf due to the subspecies' status as an endangered species.
Ground counts of wolf packs and single wolves in Arizona and New Mexico began Nov. 1. The ground count is conducted in November and December, and that period is followed by an aerial count and capture operation conducted by the IFT using helicopter and fixed-wing aircraft. The dates for the upcoming aerial count and capture operation are Jan. 21 through Feb. 2, weather permitting. Agency personnel will be limited for this year's aerial operation, and numerous precautions will be implemented to limit the exposure to and possible spread of COVID-19.
Residents of Alpine, Ariz., and Reserve and Magdalena, N.M., and surrounding areas may notice several daily flights of a low-flying helicopter over their communities during this period, as biologists conduct their annual wolf population survey and capture. Survey flights will occur on the Fort Apache Indian Reservation, Apache-Sitgreaves, Cibola and Gila national forests in eastern Arizona and western New Mexico, and possibly on some areas immediately outside the forests.
The IFT is in the process of contacting private landowners for permission to land on their property to capture a wolf, if necessary, and is coordinating with land management agencies and county sheriff offices on survey operation details. Details of the 2021 wolf population census are anticipated to be available in March 2022.

Self-organizing map learning nonlinearly embedded manifolds
One of the main tasks in exploratory data analysis is to create an appropriate representation for complex data. In this paper, the problem of creating a representation for observations lying on a low-dimensional manifold embedded in high-dimensional coordinates is considered. We propose a modification of the Self-organizing map (SOM) algorithm that is able to learn the manifold structure in the high-dimensional observation coordinates. Any manifold learning algorithm may be incorporated to the proposed training strategy to guide the map onto the manifold surface instead of becoming trapped in local minima. In this paper, the Locally linear embedding algorithm is adopted. We use the proposed method successfully on several data sets with manifold geometry including an illustrative example of a surface as well as image data. We also show with other experiments that the advantage of the method over the basic SOM is restricted to this specific type of data.

Comparison of a low-cost magneto-inductive magnetometer with a proton magnetometer: a case study on the Galali iron ore deposit in western Iran
The proton magnetometers, also known as the proton precession magnetometers, are among the most widely used instruments for magnetometry surveys, owing to their high resolution which is about 0.01 nT. As the economically attractive ferromagnetic deposits generate a magnetic field anomaly which exceeds 100 nT, this resolution is not needed for detecting such large signals. The recently introduced magneto-inductive technology has led to the development of a low-cost magnetometer that can measure the ground magnetic field up to a resolution of around 10 nT. These magnetometers are inexpensive, come in a very small size, and are lightweight compared to the more common magnetometers such as the proton precession type. In this research, a low-cost magneto-inductive sensor and a highly precise proton magnetometer are simultaneously utilized at the same profiles on the Galali iron ore deposit in the northwest of Iran. The discrepancy of two measurements is less than 400 nT, often less than 100 nT, while the changes in the total magnetic field on this anomaly are around 7500 nT, which is 11 times larger than the maximum difference between the two measurements. In addition, the value of the regression coefficient between the two measurements for all profiles is more than 0.97. Also, the slope of the fitted line for the two measurements for all profiles is close to one. These results demonstrate the applicability of the new low-cost magneto-inductive sensor in magnetic prospecting.

The Renaissance did this through things like art, literature, and later through science.
Looking at art, we can see that during the Renaissance artists came to cultivate their own styles. During the Middle Ages, art had tended to be fairly uniform, with the emphasis on the religious subject of the art. In the Renaissance, art continued to be religious in many cases, but it started to look very carefully at the human individual (think of how individual and well-portrayed the people in Michelangelo's paintings are) and it started to be done in individualistic styles. This sort of thing would have encouraged people to think of themselves in more individualistic terms. So would the writings of people like Petrarch and Dante. These ideas were then taught in the new schools that focused on humanism in education. Eventually, they led to the scientific revolution that really brought individuals' abilities to think and reason to the fore.

text: In the manufacturing process of flip-chips, ultrasonic bonding has been widely used. In the past, however, the ultrasonic horn was designed to move horizontally while the bonding force was applied vertically, the motion control of the horn thus cannot be controlled accurately. In addition, non-coplanar effects were unavoidably occurred and the quality of bonding became unacceptable. In this paper, the non-coplanar phenomenon between the horn and the substrate was attempted to improve by designing the horn with the following features: 1. The resonant mode of the horn is purely longitudinal; 2. The contact surface between the horn and the flip-chip in the substrate remain plane; The finite element method (FEM) was used to design the ultrasonic horn with the above features. In the future, the amplitude-fluctuation electronic speckle pattern interferometry (AF-ESPI) will be used to verify the FEM results.

Index Organized Table (IOT) Enhancements In Oracle 9i
The Index Organized Table (IOT) concept has matured in Oracle 9i to the point where the differences between IOTs and Heap Organized Tables (HOT) are less than the similarities.
Like indexes, IOTs are subject to inserts, deletes, block splits and coalesces, all of which affect the rowid. This means a standard rowid cannot always be used to retrieve an IOT record from a secondary index. For this reason secondary indexes on IOTs use a logical rowid which is made up of the original rowid and the primary key of the row. When a secondary index is referenced the rowid is used to find the block. If the block is not present at that disk address the primary key is used to find the block. This initial rowid access is know as a guess, since the block may not be at its origninal disk address anymore. Physical movements of the row do not affect the logical rowid, so long as the primary key is not updated.
With time the percentage of hits using the guess rowid will drop. When the hitrate gets sufficiently low the index should
be dropped and recreated to refesh the guess rowids. The guess hitrate can be monitored using the
SELECT index_name, index_type, pct_direct_access FROM user_indexes WHERE pct_direct_access IS NOT NULL;
Bitmap Secondary Indexes
A bitmap index contains a series of bitmaps that represent row locations corresponding to each key value. The bitmap can locate the row because it assumes the rows are contiguous within the block. Since this is not the case in IOTs Oracle 8i did not allow secondary bitmap indexes on IOTs.
Oracle 9i removes this restriction by introducing a mapping table which literally maps the bit position to the row
location within the IOT. The mapping table is created as part of the
CREATE TABLE statement.
CREATE TABLE countries ( country_id CHAR(2) CONSTRAINT country_id_nn NOT NULL, country_name VARCHAR2(40), currency_name VARCHAR2(25), currency_symbol VARCHAR2(3), region VARCHAR2(15), CONSTRAINT country_c_id_pk PRIMARY KEY (country_id) ) ORGANIZATION INDEX MAPPING TABLE TABLESPACE tbs_1;
Maintenance of the mapping tables causes a performance overhead so they should only be created for IOTs that need to support secondary bitmap indexes. A single mapping table can support multiple bitmap indexes on the same table.
COALESCEof secondary indexes. The base IOT is no longer locked during these DDL operations.
- Parallel DML on IOTs.
MOVEof IOTs with overflow segments. In Oracel 8i an online move was only possible if all data was stored inline.

The MPL3115A2 is a handy high precision barometric pressure that you can read from CircuitPython and Python code! This sensor provides pressure, temperature, and even calculates altitude (based on pressure) automatically for you. Best of all with a simple CircuitPython module you can read data from the sensor with ease. This guide shows how to connect a MPL3115A2 to a CircuitPython board and read data from it with Python code!
To follow this guide you'll need the following parts:
Connect your MPL3115A2 to your development board using a standard I2C connection. Here's an example of wiring a MPL3115A2 to a Feather M0 board:
 - Board 3.3V output to MPL3115A2 Vin
 - Board GND/ground to MPL3115A2 GND
 - Board SCL to MPL3115A2 SCL/I2C clock
 - Board SDA to MPL3115A2 SDA/I2C data
Installing Library
To use the MPL3115A2 you'll need to install the Adafruit CircuitPython MPL3115A2 library on your CircuitPython board.
Remember for non-express boards like the, you'll need to manually install the necessary libraries from the bundle:
 - adafruit_mpl3115a2.mpy
 - adafruit_bus_device
You can also download the adafruit_mpl3115a2.mpy from its releases page on Github.
Before continuing make sure your board's lib folder or root filesystem has the adafruit_mpl3115a2.mpy, and adafruit_bus_device files and folders copied over.
To demonstrate the usage of the sensor we'll initialize it and read the pressure and other values from the Python REPL.
import board
import adafruit_mpl3115a2
i2c = board.I2C()
sensor = adafruit_mpl3115a2.MPL3115A2(i2c)
Remember if you're using a board that doesn't support hardware I2C (like the ESP8266) you need to use the bitbangio module instead:
import board
import bitbangio
import adafruit_mpl3115a2
i2c = bitbangio.I2C(board.SCL, board.SDA)
sensor = adafruit_mpl3115a2.MPL3115A2(i2c)
 - pressure - The barometric pressure in Pascals.
 - temperature - The temperature in degrees Celsius.
 - altitude - The altitude as calculated using barometric pressure and returned in meters.
print('Pressure: {0:0.3f} pascals'.format(sensor.pressure))
print('Altitude: {0:0.3f} meters'.format(sensor.altitude))
print('Temperature: {0:0.3f} degrees Celsius'.format(sensor.temperature))
To make the altitude calculation more accurate you'll want to set the pressure at sea level for your current location and weather conditions. Barometric pressure sensors can only calculate altitude based on the pressure of air they detect and that pressure changes daily and with weather conditions. Look up your local weather forecast and it typically includes the pressure at sea level. Set the sealevel_pressure property (to a value in Pascals) to tell the chip this information and get the most accurate altitude measurements:
sensor.sealevel_pressure = 103040
That's all there is to using the MPL3115A2 with CircuitPython!
Here's a complete example that will print the pressure, altitude, and temperature every second. Save this as on your board and open the REPL to view the output. Remember to switch to the bitbangio module if necessary for your board:
# SPDX-FileCopyrightText: 2019 Tony DiCola for Adafruit Industries

# Simple demo of the MPL3115A2 sensor.
# Will read the pressure and temperature and print them out every second.
import time
import board
import adafruit_mpl3115a2
# Create sensor object, communicating over the board's default I2C bus
i2c = board.I2C() # uses board.SCL and board.SDA
# Initialize the MPL3115A2.
sensor = adafruit_mpl3115a2.MPL3115A2(i2c)
# Alternatively you can specify a different I2C address for the device:
# sensor = adafruit_mpl3115a2.MPL3115A2(i2c, address=0x10)
# You can configure the pressure at sealevel to get better altitude estimates.
# This value has to be looked up from your local weather forecast or meteorological
# reports. It will change day by day and even hour by hour with weather
# changes. Remember altitude estimation from barometric pressure is not exact!
# Set this to a value in pascals:
sensor.sealevel_pressure = 102250
# Main loop to read the sensor values and print them every second.
while True:
 pressure = sensor.pressure
 print("Pressure: {0:0.3f} pascals".format(pressure))
 altitude = sensor.altitude
 print("Altitude: {0:0.3f} meters".format(altitude))
 temperature = sensor.temperature
 print("Temperature: {0:0.3f} degrees Celsius".format(temperature))

text: The pharmaceutical inventory management process adopted by the hospitals are facing challenges in data communication, which implied to excess inventory problems as the leading cause of bad forecast of their lack. This study aims to redesign the information flow and business process in the pharmaceutical inventory management by increasing its efficiency by implementing Vendor Managed Inventory (VMI) supported by the Internet of Things (IoT). Business Process Re-engineering (BPR) and Structured System Development (SSD) as a method used in this study. Four stages of SSD consist of structuring Entity Relationship Diagram (ERD), relational table, use case diagram, and Data Flow Diagram (DFD) for process improvement. This study proposed five improvement scenarios simulated using iGrafx. The best scenario for the hospital to consider in conducting improvement is VMI intervention, IoT technology in the form of QR Code or RFID Tag, and Hospital Management Information System (HMIS) development. The proposed model resulted in pharmaceutical inventory management's time efficiency to 95.64%, which previously took 22.11 days to 7.72 hours.

Unlike battlesuits (whose weight capacity is fixed for a particular body style), mecha may upgrade their chassis in order to increase their weight capacity.
Strength Cost Modifier Max. Weight Modifier
Standard 0 None
Heavy +50% +10%
X-Heavy +100% +20%
Super-Heavy +400% +40%
Arms & Legs
The legs of a humanoid mecha are equal to 60% of the mecha's body spaces. Therefore, each leg has 30% of the body spaces. The arms are each equal to 20% of the body spaces. For example, the legs of a light mecha (with 20 body spaces) are 6 spaces each and the arms are 4 spaces each. Leg armor is half the cost and weight of torso armor. Arm armor is one-quarter the cost and weight of torso armor. The cost and weight is rounded down to the nearest whole number.
A humanoid mecha's turret is equal to 10% of the body spaces (rounded up). It has a traverse and elevation equal to a normal human head. The costs & weights for the various sizes of humanoid mecha turrets are listed below.
Size Cost Weight Internal Spaces
2-space $2,000 200 lbs 1
3-space $3,000 300 lbs 1
5-space $5,000 500 lbs 2
8-space $8,000 800 lbs 2
10-space $10,000 1,000 lbs 3
15-space $15,000 1,500 lbs 4
20-space $20,0000 2,000 lbs 5
Power Plants
Power plants of fixed size are an in-efficient use of the space available in a mecha's torso. In order to economize on the use of this interior space, modular power plants were developed. These are of three different types; electric, nuclear battery, fusion.
Type Cost/space Weight/space DP/space Power Factors
Electric $1,000 75 lbs 2 1,000/space
Electric power plants are compact, high-capacity batteries. They may use platinum catalysts and superconductors. Extra power cells are the normal cost and weight. Electric power plants store power units equal to (DP x 100). They are expended at the rate of (PU x current speed/maximum speed x 400).
Type Cost Weight DP Power Factors
Nuclear Battery $100,000 +$5,000 per space 500 lbs +100 lbs per space Spc 2,000/space
Nuclear batteries do not sustain a fission reaction. Instead, they use arrays of thermocouples to convert the heat released by radioactive decay into electricity. Nuclear batteries last for one year. They can only be refueled at facilities specially designed for that purpose. Refueling costs 20% of the battery's cost. A nuclear battery has an armored casing with 30 DP of metal armor. Inside this casing is the core, which has 10 DP. Damage to the core will reduce the battery's power capacity by 10% for every DP lost. When the last core DP is destroyed, it will begin to leak radiation (treat as a spill of mid-level radioactive waste).
Type Cost Weight DP Power Factors
Fusion $500,000 + $50,000 per space 250 lbs + 50 lbs per space Spc 4,000/space
Fusion power plants are small-scale fusion reactors. They are experimental items only, and are being considered for use by the military. Fusion power plants have the same DP as nuclear batteries. A core breach has the effects of a hit from a heavy flamer (see Ultra-Tech Car Wars). Note that the damage is taken internally.
Acceleration, Top speed & Handling
All sizes of mecha will accelerate at the rate of 5 mph per turn. Mecha drivetrains are highly efficient (even more so than battlesuit drivetrains). Accordingly, the formula (100 x power factors/power factors + weight) is used to determine top speed. Top speeds are rounded up to the nearest 5 mph.
 Mecha of any size handle differently than tracked or wheeled vehicles. Small mecha are more maneuverable than their larger cousins, but are less stable. Conversely, larger mecha are less maneuverable than smaller mecha and more stable. Accordingly, all mecha have the following modifiers to their crash table rolls; Small/medium: +2, Large/heavy: +1, x-hvy: 0, Super-heavy: -1. Titan: -2. These modifiers are cumulative with those provided by pilot skill and mecha speed.
 Small, medium and large mecha may make any maneuver of up to D4 hazard without risk. Maneuvers of D5 or greater will force an automatic control roll. Mecha of any larger size can only perform maneuvers of up to D3 hazard without risk. An automatic control roll is required if they attempt maneuvers of D4 or greater. Failure of these rolls requires a roll on the mecha crash table.
 Mecha can operate off-road without penalty. They may also move underwater at up to half-speed (maximum of 30 mph) and half acceleration.
Mecha Crash Table
2 or less: Trivial skid. Mecha keeps same orientation, but moves 1/4" in the direction it was moving before the maneuver in which it lost control.
3-4: Minor skid. As above, but mecha skids ½". No speed is lost.
5-6: Moderate skid. Mecha skids 3/4" and decelerates by 5 mph. On the next move, it performs a trivial skid.
7-8: Major skid. Mecha skids 1" and decelerates by 10 mph. The mecha performs a minor skid on its next move.
9-10: Severe skid. Mecha turns sideways and skids 1", decelerating by 10 mph per turn. The mecha has a 50% chance per turn of falling over. If this happens, the side which hits the ground takes sideswipe damage. A mecha pilot can attempt to recover from the skid by rolling for control at HC -6. Failure means that the skid continues. Success means that the mecha stops skidding and move normally in the direction it faces.
11-12: Fall. As above, except that the mecha falls over and takes sideswipe damage (multiplied by the mecha's damage modifier). It skids 1" per inch of movement, decelerating by 10 mph per turn. The mecha may not get up until the skid is done.
13-14: As above, except that the mecha takes full ram damage on the side which hits the ground (as if it had run directly into a wall).
15 or greater: Mecha falls over (as per results of 11-12), with a 50% chance of falling to the front or back. The mecha strikes its head on the ground and takes full ram damage to it. After impact, the mecha skids 1" per turn (taking normal sideswipe damage). The pilot is stunned by the impact (roll for results on the ram concussion table) and takes 1 point of damage. The use of impact armor will prevent the damage and will add a -2 bonus to the roll for stunning effects.
 This table is also used in cases where control rolls are required because of the hazards from weapons fire or collisions. When skids are made or rolls called for, they will be done in the direction opposite from the attack.
Physical Attacks
All mecha can punch once every three turns or kick once every five turns, causing half-damage to vehicles and buildings.
Mecha Size Damage/attack
Small 4d punch/8d kick
Medium 6d punch/12d kick
Large 8d punch/16d kick
Heavy 10d punch/20d kick
X-heavy 14d punch/28d kick
Super-heavy 18d punch/36d kick
Titan 20d punch/40d kick
If a mecha kicks at a target and misses, the pilot must make a control roll to prevent his machine from falling. This roll is adjusted by the modifiers from pilot skill and mecha size.
A mecha pilot can attack targets by jumping his machine up in the air and landing on top of them. This attack is known as the "piledriver" or "death from above". Success or failure is determined by rolling 2d6 and adding the level of pilot skill. A roll of 9 or better means that the mecha has landed on top of the target, inflicting 10d damage (multiplied by the mecha's damage modifier). Failure means that the mecha misses the target and lands normally. A roll of 2-3 means that the mecha falls.
Mecha can easily lift their own body weight above their heads. If the lifted object is ½ the mecha's body weight, it can be thrown a distance of 1d-3". If the object is 1/4 the mecha's body weight or less, it can be thrown 1d+2".
Mecha use full-size versions of all types of weapons. Weapons mounted in mecha arms are automatically stabilized at no extra cost or weight. Weapons mounted in the torso may have auto-stabilizers fitted at the normal cost and weight.
Mecha weapons may have magazines mounted with them in the same location, or in an immediately-adjacent body space. For example, an autocannon mounted

Computer game offers hope for Parkinson's patients
Queen's University researcher Aarlenne Khan is conducting research to determine if computer and tablet games can help improve cognitive function in people with Parkinson's disease.
Parkinson's patients gradually lose their ability to respond to the world around them as the nerve cells in the brain responsible for dopamine production die off and deprive the body of a key chemical essential for motor skills. Dr. Khan is examining whether training exercises can counteract the symptoms and ultimately slow the progress of the disease.
"Training through cognitive games has been shown to improve brain function in people of all ages so it has a lot of potential to improve function in people with Parkinson's," says Dr. Khan, a postdoctoral fellow at the Centre for Neurosciences Studies at Queen's. "We will use a task that mimics a well-established eye movement task, known as the anti-saccade task."
The experiment requires participants to look away from an object that suddenly appears on a screen. Dr. Khan will observe whether the participants' efforts to control automatic movements over time improve their attention and decision making capabilities.
Participants can complete the test at home using a computer or tablet. Dr. Khan will use a magnetic resonance imaging before and after training to determine if there are any changes in brain matter and efficiency.
Dr. Khan was recently awarded the George F. Ingram Basic Research Fellowship in Honour of Parkinson Society Central & Northern Ontario's Peterborough Chapter. The grant will provide $100,000 over two years in an effort to improve the quality of life of people with Parkinson's disease.

Its nice when games have riddles hidden in them. While playing TES:Arena, I came across an unusual logical puzzle: There are 3 cells.
If Cell 3 holds worthless brass, Cell 2 holds the gold key.
If Cell 1 holds the gold key, Cell 3 holds worthless brass.
If Cell 2 holds worthless brass, Cell 1 holds the gold key.
Knowing this brave fool, and knowing that all that is said cannot be true, which cell contains the gold key?
The correct answer is Cell 2 as suggested by the game. I wanted to know how one could logically arrive at the result. Could anyone help me with this?
What I tried: I negated all the above statements. The first implication became Cell 3 holds worthless brass AND Cell 2 does not have gold key. But if this is true, then cell 2 does not have the gold key and the result is incorrect. Hence I had this doubt.
PS: Choosing the wrong door causes man eating spiders to be released.

Does each cell necessarily contain either worthless brass or a gold key? – Sp3000 Dec 20 '12 at 12:55
Although not stated in game, there is only ONE cell with a gold key. The other cells may/may not have brass. – Gautam Shenoy Dec 20 '12 at 12:57

If you label the conditions a-c, and if the gold key exists and is unique, it is enough to show that not in 2 leads to a contradiction. But 'key not in 2' leads to 'key in 2' (so a contradiction), as follows:
By (c), not in 2 implies in 1. By (b) then, not in 3. By (a) then, key is in 2. Contradiction.
To be safe, you can check if the game makers messed up:
As 'key in 1' is a sub chain of the above, it also leads to 'key in 2'. Contradiction.
Similarly, 'key in 3' means by uniqueness that 2 holds brass, which, by (c), implies 1 holds the key. Contradiction.
Finally note that if the key is in 2, it doesn't lead to any contradictions. So game is correct.

Cell 2 cannot hold worthless brass, and cell 1 cannot have the gold key.
If a cell can have neither brass nor key, then that is the limit of what you can conclude. For example, your conditions are consistent with cell 3 having the key and there being nothing in the other cells.
But if every cell contains either brass or key, then you know cell 2 has the key. You can prove that by assuming cell 2 did not have the key, and hence had worthless brass. That implies that cell 1 has the key, which implies cell 3 has worthless brass which implies that cell 2 has the key. Contradiction.
However, if that additional condition were part of the problem, then your middle condition would be redundant.

Sorry to be contrary, but I believe you need 2 assumptions for there to be a unique solution. First, that all 3 statements are indeed true. If we allow that one or more of those statements doesn't hold, the whole thing falls apart.
Second, that each cell contains either brass or the key. No empty cells. If you disagree, try looking at these 2 solutions:
Cell 1 = Empty, Cell 2 = Key, Cell 3 = Empty
Cell 1 = Empty, Cell 2 = Empty, Cell 3 = Key
None of the 3 statements apply to either of these, so they're both possible valid solutions and you're left to guess and hope the spiders don't eat your face.
Now, you can brute force your way through by listing all possible solutions and checking which are valid under the given statements. In this case there aren't many possible choices, so that approach is not too bad. However, I'm assuming you're looking for a bit deeper insight, so I'll walk through a technique that can sometimes provide a quicker route to the answer, especially in more complex puzzles.
Since all the implications are one way (they are "if", not "if and only if"), one approach is to start by assuming a condition from the left side of a statement and trace the implications through all the statements to look for inconsistencies.
Just going in order, let's assume first that Cell 3 holds brass. Then by statement 1, Cell 2 holds the key. Since we're assuming key or brass in each and only one key, then Cell 1 would have to be brass. Given that, neither of the last 2 statements apply, so this solution is possible with no contradictions. Let's continue and check the others to be sure we have the only possible valid solution.
Looking at statement 2, let's assume now that Cell 1 holds the key. By statement 2, Cell 3 holds brass. By statement 1, Cell 2 holds the key. Since only 1 cell can hold the key, this is a contradiction. Therefore our original assumption is false, so Cell 1 does not hold the key.
Lastly, look at the third statement. If we assume Cell 2 holds brass, then Cell 1 holds the key. But we already know by our last reasoning that if Cell 1 holds the key we end up with a contradiction. So our assumption here is false, and Cell 2 does not hold brass.
Since Cell 2 cannot hold brass, it must hold the key.

If you take "not all that is said is true" to mean that at least one statement is false, you can go through negating them and see where it leads. If the first statement is false, you have 3 holds brass and 2 does not hold the gold key. Given that there is a gold key, it must be behind door 1. Then the second and third statements would be true, but we still don't know whether cell 2 holds brass.
If the second statement is false, cell 1 has gold and 3 does not have brass (so is empty). The first and third sentences are then true and we again know nothing about cell 2.
If the third statement is false, 2 holds brass and 1 does not have gold, so it must be cell 3 that has gold. The other two are then true and we don't know what 1 holds.
Since we didn't reach a contradiction from any of these, we can't choose between them. I would downvote the puzzle creator. However, if you ignore the "not all that is said is true" and believe them all, gnometorule has shown how to get there.

Kill zombie nouns in three easy steps
Zombie nouns are one of the most common problems I see in non-fiction writing. By learning how to identify and replace zombie nouns, you'll instantly improve the quality of your writing. And your readers will thank you for it!
Nominalisations, or zombie nouns, are nouns formed from other parts of speech like adjectives or verbs. They are called 'zombie nouns' because they suck life out of speech — replacing words we understand with abstract entities we don't.
Academic, legal and government writing is often cluttered with zombie nouns. Here's an example of some writing with the zombies highlighted:
A recycling project investigation is being led by Council officials in partnership with relevant government departments. This investigation will be used for the preparation of a business case with the aim of securing the Council's approval at its next meeting. The business case will describe recycling-scheme affordability and household-collection feasibility. Subject to stakeholder feedback and Council approval, the project will proceed to implementation in the New Year. The project has good alignment with the government's waste-reduction priority. Risks to the project's achievement will be monitored during implementation through a risk-monitoring process.
By converting plain words and phrases into zombie nouns, the writer has created several problems:
 - The writing sounds pompous and abstract.
 - The writing is hard to understand.
 - The writing uses complex terms that may be understood differently by different people (even within the same organisation).
Have a look at your organisation's documents, manuals or websites to see if this problem exists where you work. If it does, don't worry — zombie nouns are easily fixed!
Step 1: Take a piece of writing and list all the zombie nouns you can find.
Step 2: List the corresponding verb or adjective that you used to make each zombie noun. Here's a list of the words from our example paragraph:
Zombie noun Original verb or adjective
Investigation To investigate
Preparation To prepare
Aim To aim for
Approval To approve
Recycling-scheme affordability Affordable (adjective)
Household-collection feasibility Feasible (adjective)
Feedback To feedback or to give feedback
Implementation To implement
Alignment To align with
Waste-reduction priority To prioritise
Achievement To achieve
Risk-monitoring process To monitor
Step 3: Rewrite your work using the original verbs and adjectives.
Here's the same example, but this time the zombie nouns have been replaced by their original verbs or adjectives.
Council officials and relevant government departments are investigating ways to improve recycling. They will then prepare a business case for the Council to approve at its next meeting. The business case will explain how to make recycling affordable and whether it's feasible to collect recycling from households. If the Council approves the business case, and stakeholders support the project, the Council will implement it in the New Year. The Government has prioritised reducing waste, and this project aligns with that goal. As the Council implements the project, it will monitor any risks that could prevent it achieving its objectives.

Handmade Puppet Craft
Make your own "Ugly Doll" out of a single mitten or glove.
- Master puppeteer:Your kid.
- A single mitten or glove that's missing its mate
- Permanent markers
- Pipe cleaners
- Buttons and googly eyes
- Fabric and yarn scraps
- Fabric glue
- A hot-glue gun and glue sticks:Kids and hot glue don't mix, so make sure you do all the gluing.
- Stuffing material:Pick up some fiberfill or just raid the medicine cabinet for cotton balls.
- Plastic sewing needle
- Chopstick or knitting needle
- Send your kid on a mission in the coat closet to find an old, mateless glove or mitten. Light-colored fabrics work best.
- Then lay out the markers, buttons, googly eyes, yarn and fabric scraps and invite your kid to decorate the mitten like a monster. He can use yarn for hair, buttons for eyes or a nose, the fabric scraps for tentacles or pipe cleaners as antennae. Let his imagination go to work, while you get to work hot-gluing everything into place.
- Next, help him fill the glove or mitten with stuffing. If he's using cotton balls, have him fluff them out before stuffing. To get the fill into glove fingers or a mitten thumb, push it up with chopstick or knitting needle.
- Then show your kid how to thread a plastic needle and help him sew the bottom of the monster shut using a simple in-and-out stitch. And presto! He's got himself a scary, strange-looking new pal. Uglydoll's got nothin' on this guy!
- Not the sewing type? Have your kid seal the bottom of the mitten monster with a rubber band or use a little hot glue to seal it shut.


The Chinstrap Colony of Sando Point, Antarctica
Category: Nature
Photo and caption by Bojil Vassilev
Penguins making the most of the scarce land and raising their chicks in a dense grid of nests. The distance between nests is strictly determined by the maximum distance an adult penguin can expel his poo. Chinstrap penguins are able to generate considerable pressure to propel their faeces away from their nest. Polar scientists Meyer-Rochow and Jozsef Gal calculate the pressure at around 10 kPa, well above that known for humans and permitting the 60 cm tall penguins to defecate as far as 40 cm away from their nest. The reason for this behavior remains unknown.

Black History: Special Delivery!!
John Francis (1946 – ) is known as the Planet Walker. Francis witnessed a massive oil spill in the San Francisco Bay in 1971. He was deeply impacted the event. It caused him to reflect on how as a society, we are so dependent on oil for transportation Francis decided that he would no longer use any sort of motorized transportation. For 22 years, he walked everywhere. His travels would take him across the United States and most of South America. He hoped that his efforts would highlight American dependence on oil and petroleum.

There has been an increasing interest within the field of Marriage and Family Therapy over the last decades in uncovering and exploring how specific contextual parameters influence the life experience of minority groups. The identified experiences of minority groups include emotional and psychological responses directly connected to oppression, the effect of oppression on the couple relationship, and specific mental health needs. This dissertation adds to the existing knowledge in several ways. Specifically, the aim is to explore (1) how experiences of oppression may be present in a Scandinavian context, (2) how lived experiences affect the relationship of minority couples in Denmark, and (3) their specific mental health needs and implications for marriage and family therapists.
During this study eight couples (16 individuals) were interviewed to gain an indepth understanding of their experiences and meaning-making processes. The data was analyzed using a phenomenological method developed by Edwards and Titchen (2003) and based on the theory of Alfred Schutz (1967; 1970a). Results indicated that, as a consequence of their racial, cultural, and religious difference, the participating couples experienced that others tend to devalue them, seeing them as not-Danish, and being of lesser worth, affecting them emotionally and psychologically. This study identified several coping mechanisms commonly used by Middle Eastern couples in Denmark. This dissertation is ground breaking in Denmark, as it takes a first step toward exploring the experiences of minority couples and the emotional and psychological impact that the Danish context has on them. In addition, this dissertation makes a contribution to the field of marriage and family therapy by connecting theories developed in the United States to lived experiences in Denmark, enabling marriage and family therapists around the world to reflect on trans-cultural and trans-national processes and experiences in regards to oppression.

About the Norwegian Garnes name and the pronunciation:
Here in Norway we have at least two places called Garnes. They are not cities, but small places by the coastline. One close to the Bergen, and another close Ålesund. My family name origins from the latter. In Norwegian the name Garnes actually means something. "Gar" os "gard" means farm, and "nes" means headland. So it was as simple as a farm on some headland in the beginning. And since this is not so uncommon here, several places got the same name.
Now to the other spelling - "garnaas". This is actually another name, with another meaning and origin. "Garn" means "net", like in fishing net, but may also mean "yarn, thread, (knitting) wool, cotton (yarn)". "Aas" or "ås" means "hill" or "ridge", but may also mean "God" - the old norse gods that is.
There are around 4-5 places in Norway called "Garnaas" or "Garnås", and these are mainly located inland - not by the coast like the "garnes" farms. This may point in the direction of knitting wool and not fishing net, but this is only guessing. Maybe some norwegian called Garnaas can help?
The letter å (an a with a ring on top) is sometimes written as "aa", and I _think_ americans could say "aww" or "awe" to get the pronunciation correct.
426 norwegians are called Garnes 68 norwegians are called Garnås 43 norwegians are called Garnaas

Design of low cost, low emission marine propulsion systems
Ricardo marine propulsion experts used state-of-the-art computer aided engineering (CAE) software to evaluate the environmental and commercial performance of different marine propulsion system architectures under a range of different usage scenarios.
The work focused on the requirements of a typical harbour tugboat operating in a medium-sized European port. The general characteristics of the vessel were assumed to be a length of 35m, beam of 14m and draft of 5m, with a bollard pull of some 50 tonnes. Two alternative propulsion system configurations were considered for this vessel:
A high-efficiency conventional mechanical architecture, comprising two diesel engines powering respectively a port and starboard propeller by direct drive via a gearbox.
A hybrid electrical propulsion system based on two natural gas engine generator sets providing power to battery banks, with separate electric motors driving each propeller.
The study demonstrated the value of applying CAE simulation tools at the very earliest stages of vessel design or of repowering. From assessing the likely usage profile, the CAE tools allowed for the early assessment of detailed considerations of environmental performance, capital and operational expenditure requirements, and likely return on investment.

Fire Hydrant Inspection for Commercial Buildings
When a fire breaks out in your building, fire protection—including fire sprinklers and kitchen fire suppression systems—engage automatically in fighting the blaze. When these systems aren't enough, you count on the fire department to put out the flames completely with their powerful hoses. This requires a working fire hydrant on your property that a fire truck can tap into.
Are your fire hydrants in good working order? The National Fire Protection Association (NFPA) requires annual inspections to make sure this is the case.
If it's time to have your fire hydrants inspected, contact Unifour Fire & Safety today to schedule services. We provide fire hydrant inspections for businesses throughout the Southeast.
Why Do Fire Hydrants Require Inspections?
Fire hydrants are subject to many problems, including:
- Wear and tear
- Rust and corrosion
- Accidental damage
- Mechanical malfunction
- Accidental closing of hydrant tap valves
While you hope your building never experiences a fire, regular fire hydrant inspections help you detect and repair any damage that could prevent it from working when you need it most. The time and effort to arrange annual fire hydrant inspections is a small price to pay for the peace of mind that comes from knowing your hydrants will perform properly and reliably if you need it in an emergency.
What Happens During a Fire Hydrant Inspection?
According to NFPA 25, fire hydrants should be inspected annually and after use. At Unifour Fire & Safety, our fire hydrant inspection procedure is designed to thoroughly check that your property's fire hydrants meet all codes.
Here are the types of checks we perform during each inspection:
Assess Fire Hydrant Locations
Hydrants should be plotted correctly on water district maps. We note any errors and take steps to correct them. Hydrants should also be easily accessible and visible from all directions. No obstructions should interfere with approaching the hydrant or coupling hoses to it.
Test the Fire Hydrant
The most important part of a fire hydrant inspection is the flow test, which determines water availability for fighting fires. Here's what the test entails:
- Install a pressure gauge in preparation for the flow test.
- Open the fire hydrant fully and let the water flow for at least 60 seconds. This disperses foreign material from the water line and allows the fire hydrant to operate smoothly for an accurate pressure reading.
- Stop the flow of water and assess whether the fire hydrant drains correctly.
- Record data from the pressure gauge to determine whether it meets NFPA standards.
Inspect the Fire Hydrant
After the flow test is complete, our crew carefully examines the fire hydrant and its parts. We include the following in our inspection:
- Clean and lubricate cap threads and chains. Replace missing or cracked caps.
- Make sure valves open and close easily. Tighten leaky valves and report any valves that are difficult to operate or don't open and close fully.
- Touch up chipped paint or rusted areas with aerosol paint. Make sure any necessary markings and curb spray paint are present and easily discernible. Report hydrants that are in severe need of repainting.
Benefits of Annual Fire Hydrant Inspections
Make fire hydrant inspections a priority for your Southeast business to enjoy:
- Improved safety and peace of mind, knowing your building is protected by a functional fire hydrant.
- Insurance coverage and potentially lower monthly premiums.
- Code compliance and the chance to avoid costly fines and penalties.

Local environment surrounding Zr atoms in the thin films of nanocrystalline zirconia (ZrO2) has been investigated by using the extended x-ray absorption fine structure (EXAFS) technique. These films prepared by the ion beam assisted deposition exhibit long-range structural order of cubic phase and high hardness at room temperature without chemical stabilizers. The local structure around Zr probed by EXAFS indicates a cubic Zr sublattice with O atoms located on the nearest tetragonal sites with respect to the Zr central atoms, as well as highly disordered locations. Similar Zr local structure was also found in a ZrO2 nanocrystal sample prepared by a sol-gel method. Variations in local structures due to thermal annealing were observed and analyzed. Most importantly, our x-ray results provide direct experimental evidence for the existence of oxygen vacancies arising from local disorder and distortion of the oxygen sublattice in nanocrystalline ZrO2. These oxygen vacancies are regarded as the essential stabilizing factor for the nanostructurally stabilized cubic zirconia.

Halloween, Valentine's Day Found to Influence Birth Timing
Halloween and Valentine's Day appear to influence when expecting mothers give birth, new research at the Yale School of Public Health has found. Halloween, with its symbolism of witches and death, is treated as an unfavorable day for childbirth. In contrast, Valentine's Day, with its symbolism of flowers and love, is treated as a favorable day for childbirth. The study found a decrease in births on Halloween and an increase on Valentine's Day. The association of the two holidays with birth patterns was shown for the first time. On Halloween there was a 5.3 percent decrease in spontaneous births and a 16.9 percent decrease in cesarean births, compared to other births occurring within one week before and one week after the October holiday. Whereas, on Valentine's Day there was a 3.6 percent increase in spontaneous births and a 12.1 percent increase in cesarean births.
"The study suggests that beliefs arising from our culture can have a greater impact on physical functioning than we might suspect," says Becca Levy, lead author and associate professor of epidemiology and psychology at Yale. Study co-authors were Martin Slade and Pil Chung, also at Yale. The findings show that pregnant women may have some control over the timing of spontaneous births—traditionally believed to be beyond their control—and that scheduled births are also affected by the symbolism of the two holidays. The study drew on birth-certificate information for all births in the United States across 11 years. The Halloween period included 1.8 million births, and the Valentine's Day period included 1.6 million births. The findings are published in the current issue of the journal Social Science and Medicine.

The Sidewinder seeker is something like the CCD in a video camera. It has an array of sensors that generate an electrical signal when exposed to the infrared light given off by hot objects. Since it only sees things in terms of "very hot" and "not very hot," the infrared system is much simpler than a visible-light detection system (an ordinary video camera). Additionally, infrared seekers don't need an outside light source, so they work perfectly well night or day.
In the current Sidewinder models, the infrared sensor array is coupled with a conical scanning system. The basic idea of a conical scanning system is to continually move the feed horn -- the assembly of lenses and mirrors that directs light to the sensor -- around in a small circle (to visualize this, imagine holding the eraser end of a pencil steady in one hand while moving the pointed end around in a circle). As a whole, the moving feedhorn scans a large section of the sky. The guidance control system figures out where the target is based on fluctuations in the detected infrared light as the feed horn moves around the circle. If the target is to the left of the missile, for example, the sensor will detect greater infrared light when the feed horn is aimed to the left than when it is aimed to the right.
In the next section, you'll find out more about the guidance control system.


Leaf Curling Spider
Leaf Curling Spiders (Phonognatha graeffei) belong to family Araneidae (Orb-weavers). The spider here is a fresh leaf curling spider. They build their retreat with fresh green leaf. Most of the time they remain in their leaf retreat. They build their web near the retreat and when a prey fall on its web, it quickly pick it up from the web and go back to its retreat. The spider has a green color from under including legs and white abdomen from top. It has a yellowish-green head. It has some black spots and wavy lines on abdomen. It also has yellow and blue colored strips on abdomen. Here are some pictures of the spider taken from different angles, hoping you will like them.

Lime Butterfly Caterpillar
The Lime Butterfly caterpillar passes through 5 different instars before pupation. The first few instars of the caterpillar look like bird droppings and this is nature's way of protecting them from predators. In the 5th (last) instar, the caterpillar becomes pale green with a yellow subspiracular band having brown and bluish marking and a pair of false eyes. An additional yellow band is developed on the 4th and 5th segments with bluish spots on it.

World Atlas of Total Sky-Cover.
Environmental research papers,
AIR FORCE GEOPHYSICS LAB HANSCOM AFB MA
Pagination or Media Count:
The purpose of this atlas is to establish a global cloud climatology that details seasonal and diurnal variations. The Boehm Sawtooth Wave BSW simulation model is used to devise a method for describing the frequency distribution of total sky-cover. Two parameters, scale distance and mean sky-cover, permit the calculation of the sky cover distribution from clear to overcast. This is an efficient means of data storage, since two numbers define the entire frequency distribution. Hence, the frequency distribution of sky cover can be found for locations world-wide using the global analyses of mean sky cover and scale distance given in the atlas. Twenty maps are presented for each of these parameters - one set 4 times daily 0000-0200, 0600--0800, _PHONE_, _PHONE_ LST, for each midseason month January, April, July, and October, and another set of monthly means for all hours for each midseason month.

Two positive numbers $\alpha$ and $\beta$ are given. We are going to describe a process of choosing a random vector on the unit sphere $S$ in $\mathbb R^3$ (given by $x^2+y^2+z^2=1$).
A vector $u\in S$ is chosen uniformly at random in the spherical disc with center $(0,0,1)$ and radius $\alpha$ on the sphere. After that a vector $v\in S$ is chosen uniformly at random on the spherical circle with center $u$ and radius $\beta$.
Can we describe the distribution of $v$ on the sphere (e.g., by specifying its density function or otherwise)? Clearly, $v$ lies in the spherical disc around $(0,0,1)$ of radius $\alpha+\beta$, however its distribution doesn't seem to be uniform. Can we estimate somehow the most frequent angle that $v$ subtends with $(0,0,1)$? The answer should certainly depend on $\alpha$ and $\beta$.
(By a "spherical disc" with center $c$ and radius $r$ we understand the set of points on the sphere whose distance from $c$ is at most $r$. Similarly, a "spherical circle" with center $c$ and radius $r$ is the set of points on the sphere whose distance from $c$ is exactly $r$.)
This question arouse related to the distribution of the polarization vector in a randomly grained polycrystalline material (ceramics).

I think you can get the answer as a one-dimensional integral using the spherical law of cosines. – Douglas Zare Sep 30 '12 at 20:44
Let $\theta$ be the angle the second radius $uv$ makes with the first radius $pv$ (where $p=(0,0,1)$) and let $\phi$ be the angle $v$ makes with $p$. Then the distribution of $v$ depends only on $\phi$, which in turn depends only on $\theta$, which is uniformly distributed. Calculate $\phi(\theta)$ and take $d\phi/d\theta$ and you have your answer. I get $\sqrt{1 - (\cot \alpha \cot \beta - \cos \phi \csc \alpha \csc \beta)^2} \csc \phi \sin \alpha \sin \beta$ in Mathematica, but I did not check this carefully. – Yoav Kallus Sep 30 '12 at 21:43
