Mixtures of Linear Models
With example code in R.
So, somehow you managed to find a lot of data for which you want to fit a linear model. The problem is that there are several different categories in the data and you forgot to record which \(x\) falls into which category. Oops. This is especially bad because the relationship between your dependent and independent variables changes across categories. How do we solve this?
Finite Mixture of Linear Models
For example, let's look at the mad popular Iris dataset. We've got three different kinds of iris: setosa, versicolor, and virginica. For all 150 irises in the dataset, we have their sepal length and petal length. Clearly, there three different clusters of iris and we can run a single linear regression for each cluster to pull out the true relationships between petal length and sepal length. But, if we didn't know which iris was which, we wouldn't be able to do this with basic linear regression. That's where a mixture of linear models comes in.
The model described here uses the Expectation Maximization (EM) algorithm to estimate three linear models and infer the species of iris without any category information. The model comes from a 2010 paper by Faria and Soromenho. The basic outline is this:
 1. Initialization Step - We more or less randomly assign values to all of the parameters described below.
 2. Expectation Step - We use a normal PDF to calculate the probability that each iris is a member of each species. Then we standardize these values so that the probability that iris #1 is a setosa, versicolor, or virginica is equal to 1. It has to be one of those and only one of those.
 3. Maximization Step - We calculate three weighted linear regressions, one per species. We use all of the irises to calculate each regression, but they are weighted by how likely they are to be a member of that species (from step 2). So irises that are unlikely to be versicolor are weighted very low in the versicolor regression compared to irises that are likely to be versicolor.
 4. Then, we repeat steps 2 and 3 until the algorithm converges.

Spatial chaos of an extensible conducting rod in a uniform magnetic field
D. Sinden & G.H.M. van der Heijden
The equilibrium equations for the isotropic Kirchhoff rod are known to form an integrable system. It is also known that the effects of extensibility and shearability of the rod do not break the integrable structure. Nor, as we have shown in a previous paper does the effect of a magnetic field on a conducting rod. Here we show, by means of Mel'nikov analysis, that, remarkably, the combined effects do destroy integrability; that is, the governing equations for an extensible current-carrying rod in a uniform magnetic field are nonintegrable. This result has implications for possible configurations of electrodynamic space tethers and may be relevant for electromechanical devices.

text: The influence of fluid dynamics on the hydrodesulfurization (HDS) reactions of a diesel oil in bench-scale reactors was evaluated. The porosities and liquid saturations of catalyst beds were quantified by using the MRI technique. The gas-liquid systems used in the experiments were nitrogen diesel and hydrogen diesel. An apparatus was especially constructed, allowing in situ measurements of gas and liquid distributions in packed beds at elevated pressure and temperature up to 20 bar and 200 °C, respectively. The reactor itself had a length of 500 mm and an internal diameter of 19 mm. The packed beds used in this MRI study consisted of: (1) 2 mm diameter nonporous spherical glass beads and (2) 1.3 mm diameter porous Al2O3 trilobes having the same size as the original trilobe catalyst used in HDS bench-scale experiments. The superficial gas and liquid velocities were set within the range of trickle flow, e.g., u0G = 20–500 mm/s and u0L = 0.1–6 mm/s. In parallel with the MRI experiments, the hydrodesulfurization of a gas oil was investigated in a bench-scale plant. Its reactor had the same dimensions of the trickle-bed column used in th... mehre MRI experiments and was filled with original trilobe catalyst. These catalytic experiments were carried out at a wide range of operating conditions (p = 30–80 bar, T = 300–380 °C, LHSV = 1–4 h–1). The results of both fluid dynamic and catalytic reaction experiments were then combined for developing a simulation model to predict the HDS performance by accounting for fluid dynamic nonidealities.


text: Throughout the past two years, we've shown you various Walt Disney propaganda films from World War II. Now it's time to visit a very different mid-1940s Disney production – The Story of Menstruation. From 1945 to 1951, Disney produced a series of educational films to be shown in American schools. How to bathe an infant. How not to catch a cold. Why you shouldn't drive fast. Disney covered these subjects in its educational shorts, and then eventually got to the touchy subject of biology and sexuality. If there was ever a company suited to talk about "vaginas" in the 1940s in a copacetic way, it was Disney. Hence The Story of Menstruation. The film runs 10 minutes, combining scientific facts with hygiene tips, and it was actually commissioned by the International Cello-Cotton Company, the forerunner of Kimberly-Clark, the maker of Kotex products. An estimated 105 million students watched the film in sex ed classes across the US. And, according to Tinker Belles and Evil Queens, the film remained a mainstay in schools until the 1960s. It's now in the public domain. And you'll find it in the Animation section of our collection of 475 Free Online Movies.

What is resistance tolerance?
 1. Say I have a 20 ohm resistor with a tolerance of 5%. What does it mean to have a tolerance of 5%??
 2. jcsd
 3. berkeman
 Staff: Mentor
 The value is guaranteed to be between 0.95 * R and 1.05 * R.
 4. berkeman
 Staff: Mentor
 Another way to say it is +/- 5%
 5. So would it make perfect sense to say that for this example that the value of this resistor is guaranteed to be between (.95)(20) and (1.05)(20) which is 19 ohms and 21 ohms? Is that the correct idea?
 6. berkeman
 Staff: Mentor
 Exactly. 5% of 20 Ohms is 1 Ohm.
 7. Just one more question :biggrin:
 Say you put 2 of these resistors in series. The resistance will jump to 40 ohms but what happens to the tolerance? Will it double or stay the same?
 8. berkeman
 Staff: Mentor
 You can figure that one out for yourself, using the equation for the total resistance.
 You know that the smallest you can get is 19+19 Ohms, and the largest is 21+21 Ohms. What tolerance does that indicate.
 Now do it for the parallel resistor case.... Do you get a similar or different answer...?
 9. Oh ok I see. Just do 2(19)/40 and 2(21)/40 and you get the same tolerance of 5% I believe. In other words, whether in series or parallel, the tolerance doesn't change.
 Thanks! :biggrin:
Have something to add?

How much will it cost? / How do I calculate a payback?
The cost of residential wind turbines vary depending on how much power they can produce and other factors. A rough range is $4,000 to $8,000 per rated kilowatt. A system that would offset most of an average home's electricity use (10,000 kwh/year) will cost roughly $50,000 before incentives.
***Residential wind systems cost between "$3,200 to $5,500 for every kilowatt of generating capacity." For a 3 to 10kW system the installation costs average around $14,000 to $48,000.(If you are an electrician and have a team to help.)
How do I calculate a payback?
Determine the amount you pay on electricity bills before you install your system. If your system offsets all your electricity, you can divide its cost by the annual bill to determine how many years it will take to pay off. If you are only offsetting part of your use, you need to adjust the calculation accordingly.
Windustry offers a wind energy payback period worksheet that goes into more detail, and the National Renewable Energy Laboratory has a calculator and a paper on the economics of grid-tied small wind.

Word Breakers and Stemmers
Word breakers and stemmers perform linguistic analysis on all full-text indexed data. Linguistic analysis involves finding word boundaries (word-breaking) and conjugating verbs (stemming). The rules for this analysis differ for different languages, and you can specify a different language for each full-text indexed column. Word breakers for each language enable the resulting terms to be more accurate for that language. In the case where there is a word breaker for the language family, but not for the specific sub-language, the major language is used. For example, the French word breaker is used to handle text that is French Canadian. If no word breaker is available for a particular language, the neutral word breaker is used. With the neutral word breaker, words are broken at neutral characters such as spaces and punctuation marks.
Microsoft SQL Server 2005 includes word breakers for 23 locales. For a list of languages supported by Full-Text Search, see sys.fulltext_languages (Transact-SQL).
The language of the full-text indexed column being queried determines the linguistic analysis performed on arguments of the full-text query functions, CONTAINS, FREETEXT, CONTAINSTABLE, and FREETEXTTABLE. If no language is specified for a column, the default is the value of the configuration option default full-text language.
For a localized version of SQL Server, SQL Server Setup sets the default full-text language option to the language of the server if an appropriate match exists. For a non-localized version of SQL Server, the default full-text language option is English.
|All columns listed in a single full-text query function clause must use the same language, unless the LANGUAGE option is specified in the query.|

The government of Japan announced its decision to award Edwin A. Cranston, professor of Japanese literature, the decoration of the Order of the Rising Sun, Gold Rays with Neck Ribbon, on April 29. Cranston is recognized for his contribution in introducing classical Japanese literature to the people of the United States and other parts of the world, and in nurturing many young Japanologists.
Cranston has dedicated himself as an instructor in Japanese language and literature at Harvard for 44 years. He became an assistant professor as a specialist of Japanese literature in 1966, becoming a full professor in 1972.
Cranston has translated the Japanese waka, a 31-syllable poem, from the ancient period to the medieval period, and has introduced waka internationally with his detailed footnotes and commentary. His two volumes of "A Waka Anthology" (1993, 2006) have brought to light thousands of poems from ancient texts. Cranston's most recent book on Japanese poetry is titled "The Secret Island and the Enticing Flame" (2008).

9 HMO Questions Every Landlord wants to ask
By in Blog with 0 Comments
With the lettings industry going through some considerable turmoil in recent years, traditional letting models have become less profitable for both agents and landlords. The reduction in mortgage tax relief and elevated Stamp Duty Land Tax mean that landlords have higher costs to bear. On top of that, the tenant fee ban has shifted some of the cost of agency services from the tenant to the landlord.
Typically considered a more lucrative letting model, HMOs (Houses in Multiple Occupation) have become more and more popular amongst landlords.
HMOs are typically associated with higher yields. Despite considerable barriers to entry, HMOs can prove an excellent investment and a great way to diversify and expand a traditional Buy-to-Let portfolio. It is important to remember that as with any investment, there are risks that need to be mitigated. When it comes to managing HMOs, compliance is paramount as mistakes can lead to very serious consequences and fines.
 1. What is a HMO?
 2. Are there different types of Licensing for HMOs?
 3. What is a Mandatory HMO?
 4. What is Additional HMO Licensing?
 5. What is Selective Licensing?
 6. Other than getting a license is there anything else I need to consider before becoming an HMO landlord?
 7. How much is an HMO license and are there any other costs?
 8. What happens if I let a property that needs a license without applying for one?
 9. Who is responsible for HMO compliance?
 1. What is a HMO?
House in Multiple Occupation (HMO) is defined in section 254 of the Housing Act 2004. This definition is detailed and complex, but in the majority of cases, a HMO is a property occupied by more than two people as their main residence, who are not members of the same household, sharing basic amenities.
 1. Are there different types of Licensing for HMOs?
There are three types. These are Mandatory, Additional and Selective Licensing. Mandatory and Additional Licensing relate to HMOs but Selective Licensing can, in theory, apply to any type of tenure.
 1. What is a Mandatory HMO?
Until recently, properties with less than three storeys did not require a mandatory HMO licence, but from October 2018, this exemption was scrapped.
HMOs that meet the three tests defined in Section 254 of the Act are mandatory HMOs. These are the standard test, the self-contained flat test and the converted building test. If a property in multiple occupation does not meet any of these tests, a mandatory licence is not required.
All properties occupied by five or more persons (who are not members of the same household) are now likely to require a licence, irrespective of where in England they are located. As the tests above can be quite confusing, you are advised to speak to the local authority and obtain written confirmation that an exemption applies to your property.
 1. What is Additional HMO Licensing?
In 2010 local authorities have been given powers to introduce additional licensing schemes that would require non-mandatory HMOs to now be licensed. These are becoming more and more common amongst local authorities, who can choose to enforce licensing requirements for much smaller properties. For example, a one-bedroom property can be a licensable HMO if it is occupied by a couple and a friend sharing a kitchen and using the lounge as a bedroom.
Local authorities set their own standards which can significantly differ from borough to borough. For example, in Finchley, there is a road which is split between the borough of Barnet and Haringey. An identical property occupied by three sharers will require a licence in the borough of Haringey whilst the one in Barnet would not.
To make matters even more complicated, there are some interesting nuances even in the same boroughs. In one of the north London boroughs, ground floor flats are exempt from additional licensing. A ground floor flat in a purposebuilt block (which is exempt from mandatory licensing) could be occupied by six households without the need for the landlord to obtain a licence.
Additional licensing often poses the highest risk to landlords and tenants as one has to proactively monitor consultations and local authority notice boards to remain compliant. As with mandatory HMOs, for the belt and braces approach, one should get confirmation from the local authority on whether or not a licence is required.
 1. What is Selective Licensing?
This is the most recent addition to property licensing and can apply to any property if there are concerns over the social or economic environment of that particular area. This type of licensing is less common, however, non-compliance is enforced in a similar way to other types of licensing breaches.
HMO (002)
 1. Other than getting a licence is there anything else I need to consider before becoming an HMO landlord?
Yes. Most mortgage lenders have restrictions in their terms prohibiting HMO letting. A landlord should consult their mortgage lender first because, in some cases, they could have to change their mortgage product entirely.
Another consideration is planning consent. Article 4 directions (Town and Country Planning) can require planning change from a C3 class (which is a single household dwelling) to a C4 class, which is what most mandatory HMOs and additional licensable HMOs would fall under. Any HMO occupied by more than 6 people will be in a class of their own, also known as Sui Generis.
Minimum sleeping room sizes are set as 6.51 sqm for a single occupant, 10.22 sqm for a couple and 4.64 sqm for a child under 10 years old. Whilst local authorities cannot impose lower standards, they can decide that the sizes above are not fit for their borough and impose higher standards instead.
 1. How much is an HMO licence and are there any other costs?
Licence fees vary but they tend to be somewhere in the region of £1,000. There are councils that charge considerably more than this, however, the intention is that the cost should not exceed the cost of processing the licence application. In the case Peter Gaskin v LB Richmond Upon Thames (2018), the High Court ruled that a licence fee of£1799 was unlawful because the charge was not limited to the cost of processing the licence application.
There are also likely to be costs associated with bringing the property to the required standard in terms of health and safety. Some of these are electrical installations, certification and fire safety assessments.
 1. What happens if I let a property that needs a licence without applying for one?
This is probably the worst decision that a landlord can make.
Not only would they likely face a fixed penalty notice issued by the council, but they could end up with a criminal record, an unlimited fine and banning orders.
You should think ahead and apply for a licence before the tenancy starts. Tenants are often incentivised to report Housing Act breaches as they could have all the rent refunded to them. There have been instances where councils would collaborate with tenants and build criminal cases. These have led to successful prosecutions of both landlords and agents involved.
A typical fine for a first offence of operating a licensable HMO without a licence is in the region of £5,000. A repeat offender could be fined up to £30,000 by the council as an alternative to criminal prosecution and an unlimited fine.
 1. Who is responsible for HMO compliance?
The legislation is worded in a way where anyone responsible or complicit in an HMO breach could be prosecuted. One of the most common offences is when a person having control of or managing an HMO that requires a licence but the property is not so licensed. Section 72 of the Housing Act defines the breach and Section 263 defines "person having control of" and "person managing".
The biggest risk for agents is posed from the misinterpretation of what "rack-rent" is. The Act states that if a person receiving rent which is not less than two-thirds of the full net annual value of the premises, that person will be considered as having control of the premises. Therefore, they could be committing an offence under the Act if the property is not licensed. In recent cases heard by the tribunal and small claims courts, local authorities are choosing to interpret the net annual value as market rent instead. They are looking at the amount that the property concerned could earn in rent over a year. For this reason, even if the agent is merely hired by the landlord to perform a "tenant find only" service, the agent could end up paying a significant fine for a Section 72 breach if they collect the first month's rent from the tenant. Although this interpretation has not been challenged in higher courts yet, the fact that agents are choosing not to question it, speaks volumes and is only reassuring councils that this interpretation is correct.
The act allows local councils to prosecute both landlords and agents for the same offence. For example, although the agent collected the first rent payment, any rent paid directly to the landlord afterwards would make the landlord a person having control and/or managing the property at that point. Also, there are other offences under the Act that both landlords and agents need to be aware of before venturing into the complex business of letting and managing HMOs.
There are a huge number of considerations that landlords and agents need to be aware of before they can let or manage an HMO property. With consultations for new selective licensing schemes taking place up and down the country, we can expect more changes to property licensing requirements across the UK. As a first

Nintendo's Animal Crossing: New Leaf features a handful of leisurely activities to enjoy, chief among them fishing. There's always a great opportunity to catch one of many species that automatically appear in your encyclopedia, and it's our goal to help fill it with these fishing tips.
-You can't go fishing without the rod. Purchase one at Nookling Junction for a mere 500 bells. Upon leaving, equip it by accessing your inventory on the touch screen and select the fishing rod, which should instantly appear in your character's hand.
-To fish, be on the lookout for dark silhouettes in the water. Approach and tap the A button to cast. Always remember that the lure must be in front of the creature's head for the fish to notice it. Then wait for the fish to swim near the lure.
This part is most important. The fish will hit the lure up to five times. During which, the lure may go underwater. If this happens, immediately press A to reel it in.
-Pressing A is no guarantee you'll catch a fish. It's all in the timing.
-You don't need to rapidly press A to reel in a fish. One tap will do it.
-You don't have to stand right on the edge of the beach or grass to cast. You can move back a bit. That said, you must face the water in order to fish.
-Running too close to water will scare fish away.
-It's possible to catch other creatures like frogs and crawfish. You may even reel in a tin can.
-You can sell fish to Re-Tail for profit or donate these creatures to the Museum on Main Street.
-Caught fish automatically appear in the encyclopedia, which you can access from the touchscreen. Select the desired critter to view the season it appears (year-round, summer, etc.), the location where it was caught and record size.
-Selling fish to Re-Tail does not have any effect on the encyclopedia's contents. Once a fish is caught, it's there forever unless you delete the save file.
-Some villagers may ask to trade a valuable item for a specific fish. This decision is entirely up to you. You'll know a villager wants to trade if a musical cue plays as you pass by.
-Visit Tortimer Island to catch more exotic species. You can even purchase a wetsuit and go for a swim, whereupon which you're able to dive and pluck fish from the sea. Look for bubbles that signify a creature's beneath the surface.

Immediately after you hear that beep you can see an accident just a few yards ahead. Even if many are skeptical about the safety of these cars, the clip below can not be disputed.
In late September, Tesla introduced a new software that comes with an extra trafficking system that can detect the danger when images are not enough.
The automatic pilot can predict an accident due to the radar signal, which tells him the position and speed of the front car.

Is there a reasonably efficient algorithm for the following task?
Input: a point $x \in \mathbb{R}^d$; a convex polytope $\mathcal{C} \subseteq \mathbb{R}^d$
Find: a point $y \in \mathcal{C}$ that is as close to $x$ as possible
Assume that $\mathcal{C}$ is specified by a collection of linear inequalities, that the dimension $d$ is fairly high, and "close" is measured using $L_2$ distance, i.e., we want to minimize $||x-y||_2$. is there an efficient algorithm for this problem?
I can see how to solve this in polynomial time using linear programming if "close" were measured using $L_1$ or $L_\infty$ distance, but I'm more interested in the $L_2$ distance metric. I keep thinking there might be some algorithm based on identifying the set of inequalities that are violated by $x$ and then doing something, but I can't quite put together a working algorithm.
I found the following paper which describes an algorithm (exponential-time in the worst case but often efficient, like the simplex method):
Philip Wolfe. Finding the Nearest Point in a Polytope. Mathematical Programming, vol 11, 1976, pp.128--149.
However, that paper requires $\mathcal{C}$ to be presented as a list of vertices rather than a list of inequalities, so it can't be used for my problem. (Converting from inequalities to a set of vertices will cause an exponential blowup; typically the number of vertices is exponential in the number of inequalities.)
A quadratic program is an optimization problem where the goal is to minimize $y^T Q y + c^T y$ subject to $A y \leq b$. If $Q$ is positive definite, then this is a convex quadratic program and we can solve this problem in polynomial time using several methods, one being the ellipsoid method (originally due to Kozlov, Tarasov and Khachiyan [1]).
We can write $\|y - x\|_2^2$ as $y^Ty - 2x^Ty + x^Tx$. Thus an equivalent problem is $$ \min_y\ (y^Ty - 2x^Ty) \text{ such that } A y\leq b. $$ This is a convex quadratic program, since in this case $Q$ is the identity matrix, which is positive definite.

This paper proposes to put forward an innovative algorithm for symmetric key block cipher named as "Triple Prime Symmetric Key Block Cipher with Variable Key-Spaces (TPSKBCVK)" that employs triple prime integers as private key-spaces of varying lengths to encrypt data files. Principles of modular arithmetic have been elegantly used in the proposed idea of the cipher. Depending on observations of the results of implementation of the proposed cipher on a set of real data files of several types, all results are registered and analyzed. The strength of the underlying design of the cipher and the liberty of using a long key-space expectedly makes it reasonably non-susceptible against possible cryptanalytic intrusions.

On April 12th The June Buchanan School's elementary Grades K-5 visited the Cincinnati Zoo for their yearly class field trip. Students enjoyed a day spent with faculty, parents, and creatures of all kinds! According to the Zoo's website, over 1.2 million people visit the Zoo annually. JBS students were excited about being a part of that number as they visited more than 500 animal species and 3,000 plant species, which ranks as one of the largest zoo collections in the country.
First grade student Drake Turner said, "It was a fun trip. I got to see wolves, bears, a Komodo dragon, and a giraffe." Second and third grade students agreed by saying, "We liked seeing all the animals and spending time with our friends. We also loved the petting zoo!" When asked what their favorite animal was, the kindergartners said, "We tried to pick our favorite animal, but we loved them all so much that we couldn't. We love the zoo!"
The Cincinnati Zoo is rated by peer zoological parks as one of the best zoos in the nation and continues to make its mark as a place of conservation, education, and preservation of wild animals and wild spaces.

12 Types of Children in Ancient India
In Ancient India, 12 types of children were considered to be legal heir of his father. All of them need not be biological children of their legal father.
Manu Smriti and other dharma sastras describe 12 different ways a child can become legal heir of someone.
12 Types of Children in Manu Smriti
When a husband dies childless or is husband is either incapable of fatherhood, wife can opt for a method called 'Niyoga'.
She can request for appointment of a person for helping her bear a child. The man who was appointed must be or would most likely be a revered person. There were various clauses associated with this process, as follows:
1. The woman would agree to this only for the sake of rightfully having a child and not for pleasure.
2. The child, thus born would be considered the child of the husband-wife and not that of the appointed man.
3. The appointed man would not seek any paternal relationship or attachment to this child in the future.
4. To avoid misuse, a man was allowed a maximum of three times in his lifetime to be appointed in such a way.
5. The act will be seen as that of Dharma and while doing so, the man and the wife will have only Dharma in their mind and not passion nor lust. The man will do it as a help to the woman in the name of God, whereas the woman will accept it only to bear the child for herself and her husband.
In niyoga, the bodies were to be covered with ghee (so that lust may not take root in the minds of the participants but the actual act may take place for conception).
In Mahabharata, queen Satyavati compels her first son and sage Vyasa to perform niyoga with the widows of her third son Vichitravirya. The widows Ambika and Ambalika and one of their maids bear Dhritarashtra, Pandu and Vidura respectively.
Manu Smriti describes the child born by niyoga as a kshetraja child of the husband-wife.
12 Types of Children (Legal Heir) in Ancient India
 - Aurasa : Biological son through wife in a normal marriage, where son carries father's Y-Chromosome.
 - Putrikaputra : When there is no son, girl is treated as son and her son becomes legal heir (ex : Babruvahana, born to Arjuna and Chitrangada, but became legal heir of his maternal-grandfather.)
 - Kshetraja : Wife's womb but husband is not biological father. (ex: Kunti, Madri giving birth to pandavas). This can happen even after husband's death and still the children born will be treated as deceased father's heir
 - Dattaka : Adopted through legal method or vedic ritual.
 - Kritima : A child is nourished and brough up as a son, but no adoption rituals performed. Child grows up and assumes you as parent.
 - Gudhaja : Wife's secret son, without husband's knowledge. This child also is heir of father. Only difference with Kshetraja is, husband's approval or knowledge.
 - Apaviddha : Rejected child of some parent, but grew up with others. This child can claim property of person who nourished him, but cannot do pind-daan or death rituals to ancestors of that family (example : Karna did not or could not do pind-daan to ancestors of the adhirtha-radha)
 - Kanina : Son born to a lady before her marriage. But he becomes legal heir of his mother's future husband. (ex : Karna would have inherited the throne of Hastinapur after the death of Pandu being his eldest son as per this law, but birth of Karna was kept secret by Kunti and she revealed the truth only after the death of Karna. )
 - Sahodha : A son is brought along with the marriage. If a woman was pregnant at the time of her marriage, the son born to her after her marriage was deemed to be the son of the man who married her, even though the biological father was a different man.
 - Krita : He is a purchased son.
 - Paunarbhava : The son of a virgin widow. She after her marriage became a 'Punarbhu' ( married second time). Such marriages happened when husband dies during or immediately after marriage and wife is still a virgin. She can re-marry a person of her choice, but a son born from that marriage belongs to the family of 1st deceased husband. She can claim rights only from 2nd kid and so on..
 - Swayamdatta :Self Offered son' – When an orphaned boy went to some person and offered himself to be his son and the latter accepted his offer, the boy in such a case was called Swayamdatta.
Out of above 12, only 3 : Aurasa, Putrikaputra, Paunarbhava were entitled for full property of father and also his family's property (inherited from ancestors).
2 more : Kanina and Sahodha were also given rights to ancestral property, only if their biological father married their mother at a later stage.
Other 7 : Kshetraja, Dattaka, Kritima, Gudhaja, Apaviddha, Krita, Swayamdatta were entitled to claim only what was earned by their (social) father or his part of ancestral property, but not the entire family property. However, they can carry the surname, gotra etc.

mrs. clause defensive driving with santa
You probably think you know the whole story of Santa Claus and his eight reindeers' trip around the world to deliver presents. But believe it or not, it wasn't always a solo venture. In the beginning, Christmas was more of a mom and pop operation.
It is true, Mrs. Claus used to ride shotgun to help to navigate and keep the reindeer in line while her hubby nipped inside to drop off the goodies. But things got a little out of control and now the missus won't be caught dead riding with Santa.
The Truth Why Mrs. Claus Refuses to Ride with Santa Anymore
1. Santa is an awful singer.
Everyone knows Santa is jolly, but unfortunately, he also has the bad habit of singing Christmas carols off-key and air drumming while flying his sleigh. The embarrassment become too much for Mrs. Claus to bear when she overheard the elves snickering behind his back.
2. Santa never cleans his sleigh.
No matter how many times he promised his wife to clear out the junk from under the seats, every time Mrs. Claus rode in his sleigh she would find the floor littered with fast food bags and other trash. She couldn't take it anymore when she discovered a half-eaten sandwich hiding in the glove compartment.
3. Santa is lactose intolerant.
Despite pleas from Mrs. Claus, Santa insisted on drinking all the milk left for him by the little children. This led to extremely pungent journeys. Santa thought he came up with the perfect solution when he traded in his enclosed sleigh for an open-air model, but it was still too much for his long-suffering wife.
4. Santa never admits when he is lost.
Although Mrs. Claus is perfectly capable of reading a map, Santa always claimed he knew a "shortcut" which would save them five minutes. Inevitably, he became lost but refused to stop and ask for directions. Just recently Mrs. Claus gave him a GPS navigation unit, but he hasn't learned how to operate it yet.
5. Santa is a gearhead.
While Mrs. Claus admits there is nothing wrong with taking pride in your vehicle, she got tired of always hearing her husband brag about how much reindeer power his sleigh has. She hated when he flew at top speed but was particularly perturbed when he let her out, so he could drag race a griffin.
6. Santa is a distracted driver.
Everyone knows Santa makes a list with all the name of those who are naughty or nice. He is careful to checks it twice, but when he checked for a third and fourth time while flying his sleigh the missus got nervous. After a close call with a flock of storks delivering newborns while he was going over the list for the ninth time, she had enough of his irresponsibility.
And those are the reasons why Mrs. Claus will never ride with her husband again.
Don't force your loved ones out of your car with your terrible driving habits like Santa! Learn how to become a better driver by enrolling in a defensive driving course. Traffic School by IMPROV® offers a unique online comedy driving school for students who want to improve their driving skills, receive an auto insurance discount, and/or dismiss a traffic ticket while having a bit of fun at the same time!

Ethnic Fraternal Societies and Mutual Aid
American fraternal societies have existed since 1700s. New immigrants were usually welcomed as members in these organizations. By the 1890s, however, when millions of new immigrants from southern and eastern Europe began arriving in the United States, a rise in anti-immigrant sentiment and racist attitudes created a bias against allowing new immigrants and African Americans to join the older societies. Prevented from joining established societies like the Freemasons or Knights of Pythias, new immigrants and blacks formed their own.
"Ethnic Fraternal Societies and Mutual Aid" is a cross-curricular lesson that explores the origins, functions, rise and eventual decline of fraternal and self-help organizations among immigrants and African Americans. By studying diversity through the lens of such societies, students will learn how immigrants and African Americans developed alternative social structures that served their social, psychological, and economic needs.
The Historical Society of Pennsylvania has a rich archival collection on mutual assistance. Archival sources range from early American mutual assistance organizations, such as the Independent Order of Odd Fellows, to those organized by newly arrived immigrant groups including Italian, Irish, Polish, Russian, and Slovak. In this lesson, students try their hand at the complex task of critical analysis and historical interpretation by using primary sources drawn from HSP's collection.

Background Material for Teacher
o Beito's book-length study adopts the premise that the fraternal model was America's best effort at providing services such as low-cost medical care as well as a way to provide survival skills such as thrift, reciprocity, and individual responsibility. He adopts the premise that the fraternal society efficiently provided social welfare services that were not available otherwise in America.
Beito, David T., Gordon, Peter, and Tabarrok, Alexander, ed. "This Enormous Army": The Mutual-Aid Tradition of American Fraternal Societies before the Twentieth Century. In The Voluntary City: Choice, Community, and Civil Society, edited by David T. Beito, Peter Gordon, Peter, and Alexander Tabarrok, 182-203. Ann Arbor, MI: University of Michigan Press, 2002.
o This article outlines highlights of fraternals in the United States before the twentieth century making a case for their social and economic importance in members' lives. Beito's claim that the rise of the governmental welfare system was the key factor in the decline of the importance of fraternals is a tenuous one.
Bodnar, John. "Ethnic Fraternal Benefit Association: Their Historical Development, Character, and Significance." In Records of Ethnic Fraternal Benefit Associations in the United State: Essays and Inventories, edited by Susan H. Shreve and Rudolph J. Vecoli, 5-14. St. Paul, MN: Immigration History Research Center, University of Minnesota, 1981.
o Bodnar, an immigration history expert, discusses the significant impact of fraternal associations in ethnic communities. He cautions, however, that the economic assistance fraternal societies provided to members must not be overstated and that it never equaled the importance of family and kin.
Carnes, Mark C. Secret Ritual and Manhood in Victorian America. New Haven, CT: Yale University Press, 1989.
o Carnes begins on the premise that men's passage to manhood in Victorian America was particularly problematic. The author argues that by providing comfort and psychological guidance, the initiatory rites of fraternalism were a way to facilitate men's transition to manhood during this period.
Clawson, Mary Ann. Constructing Brotherhood: Class, Gender, and Fraternalism. Princeton, NJ: Princeton University Press, 1989.
o This book looks at fraternalism as a social construction and analyzes its many variations and transformations as they occurred with each succeeding generation. The author especially focuses on the use of ritual to create solidarity, group identity, and to deal with social differences.
Nardini, Gloria. Che Bella Figura!: The Power of Performance in an Italian Ladies' Club in Chicago. Albany, NY: State University of New York Press, 1999.
o Nardini's ethnographic study analyzes the language and behavior operating in an Italian women's social club. Included in this list because it is perhaps the only book-length study of a women's ethnic club and because of its performance approach.
Stolarik, Mark M. Growing Up on the South Side: Three Generations of Slovaks in Bethlehem Pennsylvania, _PHONE_. Lewisburg: Bucknell University Press, 1985.
o In Chapter 2, "Lodges for Everyone," historian Stolarik outlines the development of fraternal benefit societies among one ethnic group demonstrating how the lodges played an important role in reestablishing community life disrupted by the migration process.
Stolarik, M. Mark. "Slovak Fraternal-Benefit Societies in Pennsylvania." Pennsylvania Folklife. V. 44:2 Winter, 1994, 78-83.
o This article discusses the origins, growth, purposes, rituals, and decline of Slovak fraternal organizations in Pennsylvania.
Toll, Jean Barth and Gillam, Mildred S., ed. Invisible Philadelphia: Community through Voluntary Organizations. Philadelphia: Atwater Kent Museum, 1995.
o This is a comprehensive guide to Philadelphia's voluntary organizations including fraternals. It includes histories of individual organizations as well as general histories of the organizational life of particular ethnic groups.
End of Unit Assessment
Using all the information they have learned about mutual assistance and fraternals, have students write an essay either supporting or arguing against about the following statement: Modern government should carry the primary burden of providing assistance to its needy citizens. That is to say, voluntary organizations cannot be expected to relieve government's responsibility of providing basic needs to those who require forms of social and economic assistance (e.g. due to disability, medical conditions, or conditions of poverty).

What is occult bacteremia?
Occult means hidden. Bacteremia is germs (bacteria) in the blood. So occult bacteremia is when bacteria are in the blood but haven't yet caused illness or symptoms other than a fever. Because the bacteria haven't yet caused sickness, the bacteremia is "hidden."
Occult bacteremia happens in babies and children under 3 years of age. After that age, bacteremia always causes symptoms.

What are the symptoms of occult bacteremia?
The only symptom is:
Fever higher than 102° F (38.9° C)
A baby or child who has other symptoms (such as cough, sore throat, or runny nose) has an actual infection, not occult bacteremia.
How can doctors tell if my child has occult bacteremia?
To find occult bacteremia, doctors do:

The age of the child is important. Babies under the age of 3 months may need more tests and even to stay in the hospital during testing. Doctors can't always tell just by looking at very young babies whether they have occult bacteremia or a serious bacterial infection.
How do doctors treat occult bacteremia?
Doctors treat occult bacteremia with antibiotics. Your child may also be given medicine, such as acetaminophen, to reduce fever. Children under 3 months who are sent home with a fever should be seen again by the doctor in 24 to 48 hours.


Continuous Wavelet Analysis
You can use the continuous wavelet transform (CWT) to analyze how the frequency content of a signal changes over time. For two signals, wavelet coherence reveals common time-varying patterns. For images, continuous wavelet analysis shows how the frequency content of an image varies across the image and helps to reveal patterns in a noisy image.
Use Wavelet Toolbox™ to obtain the CWT of signals and images. You can use the CWT to obtain the wavelet coherence between two signals. You can also reconstruct time-frequency localized approximations to signals.

The Cleveland Metroparks Zoo and its visitors are mourning the loss of Blackie, a Nile hippopotamus.
In a release, the Zoo says the hippo was euthanized Monday due to ailments associated with advanced age.
Blackie was 59 and is believed to be the oldest male Nile hippo ever recorded.
During his time at the Zoo, the hippo sired three offspring, all males. Blackie was a fan favorite for both visitors and staff members alike.
To help the hippo as it aged, the Zoo built a special addition with a heated pool at the Africa barn in 2008. The Zoo says Blackie lived out his last years contentedly eating lots of produce and floating in the pool which he didn't have to share.
Black came to the Zoo from Africa in 1955 when he was about a year old.

Alice's strongest association is with a blonde seven-year-old in a blue pinafore who fell down a rabbit hole. Lewis Carroll's Alice's Adventures in Wonderland and Through the Looking Glass were written in the 1860s and 1870s to entertain Alice Liddell, a young girl of his acquaintance.
Carroll was a mathematician who combined his delight in games and wordplay with a profound understanding of childhood's complex fascinations.

If you establish them as well, there's nothing quiting you from doing simply.

Using Build Classes
CloudBees Accelerator provides features to organize builds in even the most complex environments. You do not need to create a build class—by default, a simple organizational structure is set up for you. But, if you have diverse product lines, or multiple product releases, you should set up and use build classes.
A build class is a flexible, user-defined classification for a designated group of builds. Using build classes is optional, but if you do not assign a build class, the Cluster Manager assigns the build to a default build class. Build classes help you organize the build management process.
Depending on your company requirements, you might use build classes to organize build groups by version or release, product type, development stage, or platform. You can decide how to use build classes to organize your builds into sets.
Classes have default priorities and boost values. Boost values have a range of -10 to +10 (default 0), where a higher value means that builds in that class can use available agents ahead of builds with the same priority but less boost.
Tag Definitions
Each build in a class is identified by a unique string called a tag. The build tag definition is a template that expands when a new build starts. The tag is user-defined and generally consists of a generic build name appended with build-specific data constructed from the following variables:
Globally unique number (Global Counter)
Number unique to the build class (Local Counter; the build serial number within the class)
User-defined build class name
System-generated number that the Cluster Manager uses to identify each class
Name of the user who invoked eMake
Name of the machine where eMake was invoked
Label specified at the eMake command line. For example, --emake-build-label=my_build
Operating system ID under which the build was invoked. ( 0 = undefined, 1 = Windows, and 3 = Linux)
Build start date and time using variables Y, y, m d, H, M, S. Ffor example, 2005-01-18 10:14:32 is 20050118101432
Year at build start time ( YYYY )
Year at build start time ( YY )
Sequential month number at build start time ( 1-12 )
Sequential day of month at build start time ( 1-31 )
Hour of the day at build start time ( 0-23 )
Minutes at build start time ( 0-59 )
Seconds at build start time ( 0-60 )
Abbreviated day of week at build start time ( WED )
Full name of the day of week at build start time (such as Wednesday )
Abbreviated month name at build start time (such as AUG )
Full month name at build start time (such as August )
Build start date and time using the variables A, B, d, H, M, S, Y. For example, 2005-01-18 10:14:32 is 18/01/05 10:14:32.
Together, the build name and variables are referred to as the tag definition. Variable names are case-sensitive.
For example, the tag definition %BUILD_CLASS%%LC%%DATE% for a build class named QA_BUILD creates the following build tag:
When assigning build class tag definitions, choose from the list of tag variables above.
Build Class Examples
Suppose your company has two major product lines: SuperSoftware and MegaSoftware. SuperSoftware runs on Windows and Linux platforms. MegaSoftware runs on Windows only. You could begin by setting up three classes that include the product name, the platform, and the current version number for each product:
 - You could name the first class SuperSoftware_Win_v.2.1. The tag definition for this class would be:
The result would be a series of builds each named, or tagged, with the product name, the platform, the version number, a serial number (unique to the class), and the date for each build. For example:
 - The second class could be named SuperSoftware_Lin_v.1.7. The tag definition can be the same as in our first example, because it would be distinguished by the second build class name. Build tags in the second class would look like:
 - The third class could be named MegaSoftware_Win_v.1.3. For this product, the tag definition would be similar to the previous examples but also could include the name of the user who started the build, because the MegaSoftware team is spread over several different locations. For this class, the tag definition might look like:
 - As in the first two examples, the result would be a sequentially-numbered series of builds with the product name, platform, version number, name of the user who ran the build, and date of each build assigned through the build class:
Additional classes could be created when the development of SuperSoftware or MegaSoftware entered a new phase, such as a new platform release or a new version release. In this way, the builds for each stage of development can be segmented into logical sets for a more manageable and organized workflow.
Creating a New Build Class Using the Cluster Manager
 1. Open a web browser and go to the Cluster Manager host.
 2. Click the Build > Build Classes tab.
 The Build Classes page displays.
 3. Click the New Build Class link.
 A blank class details screen appears.
 4. Click the Show Help link on the right side of the screen to see field descriptions,and then fill in the fields accordingly.
 5. In the Tag Definition text box, enter the build class tag definition.
To avoid errors, follow standard naming conventions for tag definitions by using numbers, letters, and underscores only without leading or trailing white spaces. Use underscores ( _ ) instead of spaces. Use a percent sign on either side of any variables used. (For example, %DATE% ).
 1. Continue filling in the fields.
 See the online help for more information if needed.
 2. Click OK.
You can add comments to the build class. To do so, click the Build > Build Class tab, then select a build class name. For details about on adding or editing build class comments, adding or editing class properties, or deleting a build class, see the online help.
Using an Existing Build Class
Assign the build's class name through the --emake-class= eMake command-line option when the build is invoked. If you do not assign a build class, the Cluster Manager assigns the build to the default class. If the class name typed on the eMake command line does not match a class name already in the Cluster Manager, eMake exits.
Makefile Macros
eMake automatically creates makefile macros ( ECLOUD_BUILD_CLASS and ECLOUD_BUILD_TAG ) from Cluster Manager build class data. These macros can be used to place generated values in your makefiles. For details, see the " Using eMake Variables " section.

Ria Formosa
Natural paradise between land and sea
The Ria Formosa Nature Park is a unique lagoon system that is continually changing because of the movements of winds, currents, and tides.
A gift of nature, of approximately 18,000 hectares, it is an area of transition between land and sea skirting 60 km of the Eastern Algarve coastline, between the Ancão peninsula and the Manta Rota beach in the East.
This internationally recognised wetland is an invaluable habitat for wildlife: flamingos, buzzards, woodcocks and kingfishers. However, the symbol of the park is the purple swamphen, a rare species which, in Portugal, only breeds in these lakes. Another inhabitant of this wetland is the chameleon, which is at risk of extinction elsewhere in Europe.
This is a micro-environmental world, which can only be discovered by following walking trails or going for slow boat trips to observe the wetland, fresh water pools and ancient Roman salting tanks. Uncover and learn the secrets of the forests, and see the restored tide mill up close.
Quinta de Marim, headquarters of the Nature Park, is located close to Olhão. Apart from an Environmental Education Centre, it has a hostel where you can stay overnight, a Bird Recovery Centre and a kennel dedicated to breeding water dogs, an endangered Algarvian species.

Food as a Tool of Diplomacy & as a Weapon of War
As part of the Policy in Practice Series presented by the Public Policy program, Delaware Valley University was proud to host Dr. Maria Velez de Berliner and her presentation on Food as a Tool of Diplomacy and as a Weapon of War this past Thursday. Dr. Velez de Berliner is president of the Latin Intelligence Corporation and a professor of political violence and terrorism at George Washington University. She is a leading analyst and author of intelligence products and reports and has worked with the U.S. Department of Defense and the U.S. Department of Homeland Security. She has a master's in public and international affairs, with a specialization in international security and intelligence, from the University of Pittsburgh.
Dr. Maria Velez de Berliner
The presentation on Food as a Tool of Diplomacy and as a Weapon of War examined major global issues impacting food production and availability, including how food can be used to solve conflict among nations and how food can be more powerful than weapons when used to manipulate a population by depriving the people of food.
When discussing food as a tool of diplomacy and the role food plays in peace negotiations and conflict resolution such as Somalia and South Africa, Dr. Velez de Berlin pointed out that even when two countries are at odds with one another, it is important for the two groups to take a break from their negotiations and sit down and enjoy a meal together. In line with proper table etiquette, politics are often avoided during such occasions, further allowing the groups to communicate and connect in other ways. Often times, these groups may be able to see each other in a new light. The use of food in this context can be defined as gastrodiplomacy, ultimately the intersection of gastronomy (the study of food) and policy. From this perspective, food can be used as a means to relay cultural values and history.
There are a few organizations who have realized the power of food to bring people together:
 - In Detroit, the Peace Meal Kitchen is a low-profit organization dedicated to educating diners on regions that are either misrepresented by the U.S. media or are struggling with political conflict. Their hope is to not only humanize other cultures that are not easily accessible but also create awareness of the rich diversity that exists within the metro-Detroit area. During your dining experience, you will learn about the geography, culture, and people of the country of focus. rotates identities in relation to current geopolitical events.
 - The Virtual Dinner Guest Project is an international multimedia initiative born from a simple premise: It is harder to ignore, vilify or harm those we have broken bread with. The Virtual Dinner Guest Project facilitates interpersonal connections through our dinner table discussions via Skype.
Ultimately, even if food is available, it may not be accessible. As our population continues to skyrocket, issues of food availability are becoming more prominent. Dr. Velez de Berliner believes that technology is a key factor in addressing sustainability issues of the future. She suggested three applications of technology that could aid in food availability and accessibility:
 1. Hydroponic systems: a plant production system that operates by circulating water. As opposed to a single use of water in the production fields, the circulation of water in hydroponic systems allows for the reuse of water many times. Hydroponics can help reduce the amount of water being used in agriculture which will ultimately allow that water to replenish aquifers and to be used elsewhere.
 2. Genome editing: the genetic manipulation of crops has allowed scientists to breed plants for specific traits that result in more resilient crop varieties. Desirable traits include pest resistance and better water utilization.
 3. Drones: although this isn't new technology, the idea of using drones in agriculture is a concept that has recently gained interest. Drones can be used to in soil and field analysis. They produce precise 3-D maps for early soil analysis, useful in planning seed planting patterns. After planting, drone-driven soil analysis provides data for irrigation and nitrogen-level management (MIT Technology Review).
As stated by in MIT technology review, agricultural producers must embrace revolutionary strategies for producing food, increasing productivity, and making sustainability a priority (MIT Technology Review).
As the worldwide population continues to grow, estimating 9 billion by 2050, the key question becomes this: how we are going to live on a planet with built-in limitations? Furthermore, as food availability and accessibility become more of an issue, how will food be used to address issues of conflict and violence that we are all too familiar with today? We are already seeing incidents where food accessibility is being used by those in power to manipulate large populations of people. These incidents are issues on their own without factoring in the population growth we can anticipate in the future. Also, as the population of our plant increases, arable land available for food production decreases. How can we expect to feed more people when we are confronted with increasingly limited resources? How is it that the US, among the wealthiest countries in the world, is experiencing 48 million who are nutrient deficient? Food availability and accessibility is a sustainability issue that will only be exacerbated unless we take the necessary measures to find solutions.

up of heterogeneous adsorption patches .
3.3. Two-Level Factorial Design of Experiments
Dye removal by an adsorbent in a batch experiments usually depends on many factors. These factors include contact time, adsorbate dosage, pH, and so forth. To systematically explore process options, a full-factorial two-level design on the key factors was set up as shown in Table 3.
Only three factors affecting dye adsorption efficiency were studied in this work, including contact time, adsorbent dosage and pH. The first factor, contact time is numerical because it can be adjusted to any level. Also, the second factor, dosage and the third factor, pH are also numerical. None of the factors used in this design is categorical, that is factor that cannot be adjusted. The experiments for two-level factorial design were carried out in a set of 250 ml conical flasks containing 80 ml MB and BG dyes solution of known pH, adsorbent dose and agitated for predetermined contact time. After thirty and ninety hours of agitation, the suspensions were filtered and dye concentrations in the supernatant solutions were measured using a UV-Vis spectrophotometer. The experimental design results were analysed using DESIGN EXPERT software to estimate the statistical parameters as well as effects, such as half-normal probability of the standardized effects, Pareto, interaction and main effects plots. 23 two-level factorial design with 8 runs experimentation for MB and BG removal was studied, and amatrix was developed according to their low and high levels, represented by −1 and +1, respectively. The coded values of variables with the responses (% removal efficiency) were illustrated in Table 4.
The interactions between independent variables were determined with ANOVA and the main effects of MB and BG adsorption were identified based on the P value with >95% of confidence level.
The codified equation below was used to explain the 23 factorial designs of MB and BG removal by four different activated carbons:
Table 3. Test factors for dye adsorption.
where Y is the predicted response, β0 is the intercept, βi is the regression coefficient related to the interactions and the main factors effects A is the contact time (mins), B is the adsorbent dosage (g), and C is the pH. The interaction and main effects, regression coefficients, coefficients of the model, standard deviation of each coefficient, standard errors, and T and P values were also done.
From Table 5 and Table 6, when the factor effect is negative, removal efficiency decreases as the factor is changed from low to high levels (as seen from dosage and pH). In contrast, if the effects are positive, removal efficiency increases for high level of the same factor (as seen from adsorbent dosage and pH). When the factor effect is negative, removal efficiency decreases as the factor is changed from low to high levels (as seen from pH and contact time). Furthermore, the fit models, submitted square correlation coefficient (R2) of 0.9992 for MB and 0.9939 for BG, were in good agreement with the statistical model. The factors A, B and C are the frequently called a main effect as it refers to the primary factor of interest in the experiment and factors AB, AC and BC are interactions effects. In this work, factors A, B, C AC, and BC are all significant effects. The AB and ABC effect were insignificant, when it was compared with other

Table 6. Interaction of dosage versus pH.
effects. Thus the AB and ABC effects were neglected and did not included in the model equation. Then, model equation, related to the level of parameters and removal efficiency, was obtained by substituting the regression coefficients in for both MB and BG:
Equations (4) and (5) indicated that two-variable interactions were significant. Proof of positive (BC) and negative (AC) interactions was quite strong, thus, could not be ignored from the model. Although the main effects gave a clear idea, the interaction between those two parameters would favor a better statement of the process.
The interactions between independent factors were determined with analysis of variance (ANOVA) and the main effects of dye adsorption were identified based on the P value with >95% of confidence level are presented in ANOVA Table 7 and Table 8. The tables presented the possible positive and negative two-variable interactions among the variables A, B, and C for the removal efficiency (%).
Table 7. Statistical parameters and ANOVA for removal efficiency (%).
Table 8. Statistical parameters and ANOVA for removal efficiency (%).
It was observed that the effect of pH was more noticeable when the adsorbent dosage was high but at lower adsorbent dosage, effect of pH was not so high. On the contrary, pH effect and adsorbent dosage effect were high at higher contact time. The interaction effects are easily estimated and tested by using the ANOVA as shown in Figure 3. The ANOVA results of MB and BG were shown in Table 7 and Table 8 above. The sum of the squares used to estimate factors affect and Fisher's F ratios (defined as the ratio of mean square effect and the mean square error) and P values (defined as the level of significance leading to the rejection of the null hypothesis) were also represented. Relative importance of the individual and interaction effects was given by the Pareto chart of the standardized effects in Figure 4. In order to identify whether the calculated effects were significantly different from zero, Student's t-test was performed and horizontal columns in Pareto chart showed these values for each effect. The normal probability plot of the standardized effects with P = 0.05 to evaluate the significance of each factor and its interactions on removal efficiency (%) are presented in Figure 5. Half-Normal probability plot could be separated into two regions, the region on the right side has all the effects that were significant. For a
Figure 3. Interaction graph of dosage versus pH for MG and BG.
95% confidence level and seven degrees of freedom, Bonferroni limit was 11.7687 and t-value limit was 4.30265 for MB and BG adsorption. The minimum statistically significant effect magnitude for 95% confidence level is represented by the vertical line in the chart. Five values higher than 4.30265 (P = 0.05) were located at left of the dash line and were significant. It can be concluded that the adsorbent dosage was the strongest effect of the overall adsorption procedure for both MB and BG SCAC. The first (strongest effect), second, third, fourth and fifth important factor to the overall optimization of the batch adsorption process were arranged in sequential order in Pareto chart for both MB and BG. Factor B, A, C, AC and BC show the order of significant of each effect on MB adsorption

process. Similarly, factor B, C, A, BC and AC show the order of significance of each effect on BG adsorption process. The coefficient of AC interaction for both MB and BG adsorption had the negative value; thus, a decrease in contact time of the solution with a deduction of the pH caused an increase in removal efficiency (%). This antagonistic effect would not be distinguished in the univariate optimization of the dye removal process.
Carbon produced by chemical activation of carbonized coconut shell, eucalyptus tree, corn cob and flamboyant pod with an activation agent 63% H3PO4 were all capable of removing Methylene Blue and Brilliant Green dye molecules from aqueous solutions. The adsorption was favoured at Basic medium with pH value 11 and adsorption efficiency (%) was also found to increase with the increase in adsorbent dosage and contact time.
The equilibrium data were in good agreement with the Freundlich model. Additionally, the influence of pH (4 and 11), adsorbent dosage (2 g and 5 g) and contact time (30 mins and 90 mins) on removal efficiency (%) was designed by using 23 two level factorial design. It was examined by using analysis of variance (ANOVA), t-test, and Bonferroni? test. According to Pareto Chart, half-normal, normal probability plot, main effects, interaction plots in variance analysis, the most significant factors on removal efficiency (%) were found to be adsorbent dosage (B), contact time (A), pH (C), the interaction between adsorbent dosage and pH (BC) and interaction between contact time and pH (AC), respectively.
Due to the obtained results, black carbons which are produced from chemical activation of carbonized coconut shell, eucalyptus tree, corn cob and flamboyant pod could be employed as an effective and low-cost adsorbent. Therefore, these successful adsorbents could be considered as an alternative to commercial activated carbons for the removal of reactive Methylene blue and brilliant green from aqueous solutions.

The Hermite polynomials are defined as $$H_n(x)=(-1)^n e^{x^2}\dfrac{d^n}{dx^n}e^{-x^2}.$$

By induction, $H_n$ is a polynomial of degree $n$. Its roots are the zeros of $u_n(x) = \frac{d^n}{dx^n} e^{-x^2}$. But by Rolle's theorem, between any two zeros of a differentiable function there is a zero of its derivative. The same is true between a zero and $+\infty$ or $-\infty$ for a function that goes to $0$ at $\pm \infty$.

Advanced investors and traders need different technical tools than beginners because they require more sophisticated analysis. Advanced investors often use complex strategies that involve multiple variables, such as options trading or hedging. Complexity in trading automatically means that experience is required to make quick and effective decisions.
Advanced traders may also use specialized software programs with features like charting, backtesting, automated trading systems, or algorithmic trading capabilities to gain an edge over other market participants. By having access to these powerful tools and resources, advanced investors can better understand the markets they are participating in.
One such type of program is called MAM which stands for Multi-Account Manager and is extremely helpful for experienced traders to manage their portfolios more effectively. This is what we will cover in this article. We will show you a detailed picture of its explanation as well as specifics of its working.
Everything You Should Know About MAM Program
MAM (Multi Account Manager) is a trading program designed for professional traders and money managers. It allows them to manage multiple accounts from one platform, allowing them to trade more efficiently and on a larger scale. The main features of MAM include automated order execution, risk management tools such as stop-loss orders and margin control, portfolio customization options including asset allocation strategies, account segregation capabilities for managing funds in different currencies or regions separately, and advanced reporting capabilities.
The main advantages of using the MAM program are increased efficiency through automation; improved risk management due to better monitoring, higher returns through optimized portfolio construction, greater transparency with detailed reports, faster trades due to real-time updates across multiple accounts simultaneously, cost savings by reducing manual labor involved in managing each account individually.
MAM programs can be difficult for beginners to use in trading due to the complexity of the program. So using it requires a certain level of experience and understanding. Advanced traders or investors have more experience making them better equipped to take advantage of their features such as risk management tools, advanced order types, portfolio optimization strategies, and more. As a result, the MAM Forex program for managers makes them able to maximize profits while minimizing risk by using sophisticated techniques that may not be available or accessible to novice users.
Additional Information About The Program
Using a MAM program in trading effectively requires knowledge of the financial markets and an understanding of how to use the technology. It is important to understand the different types of orders available, such as market orders, limit orders, stop-losses, and take profits. Additionally, traders should be aware of any fees associated with using the platform and familiarize themselves with its features.
Furthermore, it is essential for traders to have a good risk management strategy in place before utilizing MAM programs for trading purposes so that they can maximize their returns while minimizing losses at all times. Finally, having access to reliable data sources will help ensure informed decisions when making trades through an automated system like MAM.
But on the other hand, note that MAM is not the best tool to use in trading on all occasions. For example, if you are a novice trader and do not have experience with MAM systems, it would be unwise to rely solely on this technology for your trades. Additionally, MAM systems can be expensive and may require additional resources such as specialized software or hardware.
Furthermore, many traders prefer the more manual approach of placing orders individually rather than relying upon an automated system like MAM which could potentially lead to errors in execution due to a lack of oversight or understanding of how the platform works.
Other Programs You May Use In Trading
As you saw, MAM is very helpful but there are many other programs that may increase potential as well as the quality of trading. For example, automated trading bots can help you make decisions based on market data and trends. Additionally, charting software such as StockCharts or TradingView can give you an edge by providing technical analysis tools to monitor the markets.
Finally, portfolio management systems like Wealthfront or Betterment provide users with personalized advice regarding their investments and strategies to maximize returns while minimizing risk. All of these programs have the potential to help traders make better-informed decisions when it comes time to buy and sell stocks or other assets in the financial markets.
To use MAM and similar programs in trading effectively, certain skills are required. These include an understanding of the markets, a good knowledge of financial instruments and how they work, as well as technical analysis skills. Additionally, traders need to be able to interpret data quickly and accurately so they can make informed decisions about their trades. They also need strong risk management abilities in order to limit losses while maximizing profits. Finally, traders should have excellent communication skills so that they can collaborate with other team members when making important decisions or executing trades on behalf of clients.
