The town of Ajax, one of the many bedroom communities that sprawl out from Toronto's border, has a waterfront unlike many of its neighbours. With the exception of one private property, it's seven uninterrupted kilometres of publicly owned, publicly accessible land, the longest stretch in the Greater Toronto Area. In the warm months, it's a runner's or cyclist's paradise: a seemingly endless stretch of green grass and tangles of trees lining the water of Lake Ontario.
But Ajax, a town of 110,000, is in a fight to protect its shores from the burgeoning population of York, the region on its western flank, and the proposed doubling of the sewage to be treated in Ajax's lakeside plant. For Mayor Steve Parish, more sewage means more algae, the pungent green nuisance that already imperils the town's beaches, rendering them unusable for much of the summer.
This particular species of algae, called cladophora, is common throughout the Great Lakes except Lake Superior. It proliferates when it has access to lots of phosphorus and light – both of which are in abundant supply along Ajax's shore. It grows on rock surfaces in the spring and then detaches and floats to the shore from the middle of the summer until mid-September. The mayor believes it threatens the future of his town.
"Developers in York Region, in developing and selling 150,000 household units, will get very significant profits from this on the backs of the people downstream – the people in Ajax," Mr. Parish said.
The local sewage treatment plant, jointly owned by Durham Region (which governs Ajax) and the more populous York Region, plans to increase the amount of sewage it treats from its current 340 million litres per day to 620 million litres per day in the coming years, in step with the anticipated population increase of 400,000 in York by 2031. The Duffin Creek Water Pollution Control Plant expels treated sewage (known as effluent) one kilometre off the shore of Lake Ontario, and the Town of Ajax believes the phosphorus in the effluent is causing the algae to take over its shoreline.
But the science is inconclusive: Some studies suggest stormwater and zebra mussels may be even more important factors in algae growth.
"It's not just fouling the beaches in terms of making them not swimmable or the rotting of the algae causing smells," Mr. Parish said. "We are a Lake Ontario waterfront community, and the waterfront has major economic impact in terms of the growth, tourism, etc. of our community." He's called for a study to look at its effect on E. coli in the area, as well, as he believes the algae traps and re-emits E. coli near Ajax's shore, which may be responsible for the frequent beach closings in the town in the summer months.
While the Town of Ajax believes the water quality along its shoreline will be most affected by this change at the sewage treatment plant, the two-tier government structure prevents it from having equal say in the decision. How this extra demand on the system will be managed is ultimately up to Durham and York regions (as well as the province's Ministry of Environment), which have called for a relatively minor adjustment to the equipment used to release the effluent into Lake Ontario rather than more drastic and expensive measures proposed by Ajax. The town favours adding an extra stage of treatment for the sewage to separate out more phosphorus and to release the treated sewage further offshore.
Durham and York regions are nearing the end of an environmental assessment on modifications to the plant that began in 2010. As part of that process, they hosted public consultations last week in Pickering, where the plant is located, and neighbouring Ajax. The Ajax meeting drew a crowd of about 80 locals, who pressed the two regions, as well as the consultants running the project, to "be leaders" in tackling the water quality problem in Lake Ontario.
"We fully recognize that cladophora is an issue for the Ajax-Pickering area. We don't dispute that," said Barry Laverick, a project engineer with Durham Region, at the meeting. "We've spent a lot of time and a lot of effort ranking the alternatives."
At the heart of the dispute is the cause of the algae growth.
The Town of Ajax cites a University of Michigan study that points to the phosphorus from the sewage plant's effluent as the culprit behind the algae, but the two regions have turned to other research from other sources, including the University of Waterloo, that suggests stormwater and the infestation of zebra mussels in Lake Ontario have more to do with the algae growth.
"There's no one gigantic source. If there was, it would be easy to deal with," said Peter Dillon, a professor at Trent University's Water Quality Centre and a Canadian expert on the biogeochemistry of lakes. "It's the cumulative effect of a lot of smaller sources, and you have to deal with them all best you can."
While he hasn't completed studies of Ajax's near-shore area, Dr. Dillon said the regions of York and Durham may very well be right that storm water is the biggest contributor of phosphorus to that part of Lake Ontario. But he said it's always easier to manage the phosphorus levels coming from a "point source," such as a sewage treatment plant, versus a broad range such as a lawn-fertilizer nutrients, dust on roads and agricultural runoff that could all end up in stormwater.
On a walk along the water in Rotary Park near the mouth of Duffins Creek (at this time of year, it's naked trees and calf-high slush), Mr. Parish said that since there's no consensus on the cause of the algae, the regions should put the environmental assessment on pause and commission an extensive study of the water quality along Ajax's shoreline – or even wait until a provincial study currently underway on the health of Lake Ontario is completed.
In the meantime, the Town of Ajax has submitted two alternative ways to handle the added pressure on the sewage-treatment system coming from York Region. One is constructing a longer outfall (the pipe that carries the effluent into the lake) from its current length of one kilometre to three kilometres. Both the town and the two regions agree the deeper water three kilometres offshore would allow for better dilution of the effluent, which could mean less algae on the waterfront. But that option comes with a $185-million to $240-million pricetag.
The town has also proposed tertiary treatment: an extra few stages of sewage treatment that would remove more phosphorus from the effluent prior to its release. The regions say not only would it be expensive (between $175-million and $230-million) but it's the option with the biggest carbon footprint, since it would involve constructing two new buildings on the plant's site. John Presta, Durham Region's director of environment services, says it won't do much to combat the algae in the lake, either.
"Tertiary treatment is like adding a clean drop of water in a bathtub. It's not going to provide much impact," he said.
But regardless of which research or modifications to the plant residents prefer, most who attended the public consultation seemed most riled up about the regional politics behind the plant's expansion.
Walter Donaldson, 66, who has lived in Ajax for almost three decades, said he thinks York and Durham regions have put cost-effectivness before all else in deciding how to handle the increased demands for sewage treatment from residents of York Region.
"There's a big pipe coming down from York Region – they were saying in [the meeting] it's 80 per cent from them," Mr. Donaldson said. "The town [of Ajax] isn't getting the responses they want. It seems to me like they're trying to rush this through."
York Region officials say they've listened and responded to the Town of Ajax's concerns, but say the option they've selected makes the most sense for the region when all factors – including social and financial – are considered. While some sewage from the region is sent to a plant along Lake Simcoe for treatment, it's not feasible to direct sewage from all future development there.
"The regions have expended a significant amount of money to go above and beyond the minimum requirements for an environmental assessment," said Daniel Kostopoulos, York Region's director of capital planning and delivery. "We're spending millions of dollars on it to make sure we get things right."

- Archive Workshop in the Jewish Museum Berlin
© Jewish Museum Berlin
Project day: Archive Workshop
How does an object make it into the Museum?
Numerous collections of individuals and families are kept in the Jewish Museum Berlin archive. Certificates, letters, manuscripts, photographs, and everyday objects from work and home tell of the lives and fates of the German Jews.
Guided by museum educators, the young people will explore themes such as emigration or daily life under the Nazis using archival material. Writing explanatory texts on the findings and making suggestions as to how they should be exhibited will be part of the presentations, thus offering insight into museum work as a profession.
Working with original materials makes this dip into the history and culture of German Jews a deeply personal one that goes far beyond the general historical context. A theme-oriented tour can be added to the workshop on request.
From May to June 2013, contemporary witnesses will visit from England and elsewhere. We look forward to welcoming Rudi Leavor (born in 1926 as Rudolf Librowicz), who attended school in Berlin until 1937. His parents were arrested by the Gestapo in 1936 and following their release, they tried to leave the country as soon as they could. The family succeeded in emigrating to England in 1937 with a family-owned Torah scroll in their luggage. Rudi Leavor now lives in Bradford where he is cantor at a Reform synagogue. He donated the Torah scroll – saved through its transport to England – to the Jewish Museum Berlin where it can now be seen in the current temporary exhibition "The Whole Truth."
A further object for which the Jewish Museum Berlin has Rudi Leavor to thank can be viewed here.
Appointments in early 2013 on request
Jewish Museum Berlin
Grades 9 to 13
Number of participants
10 to a maximum of 20 pupils

Using prepared statement is favorable in two regards: It is more efficient than direct execution of SQL code, since a statement that is used repeatedly needs to be parsed, analyzed, and, optimized only once. This can lead to a significant performance gain, depending on the complexity of the statement. Secondly, since no user input is used to create the SQL statement, but parameters are only passed as function arguments when the statement is executed, SQL injection is effectively prevented.
So here is a short example of how to use this from Lua using the luapgsql interface.
First, connect to a database:
local conn = pgsql.connectdb('')
Using a prepared statement is a two step process. First, the statement needs to be prepared. This is done only once per connection using the prepare() function.
When preparing a statement, use $1, $2, $3 in the SQL code as placeholders for the actual data parameters, which will be supplied later, when the statement is being executed. To give PostgreSQL an idea which data types you will be using you have to supply "example" parameters to the prepare() function. The value of the parameter will be ignored, it will only be used to determine the data type. In the example below a prepared statement with name'myselect' and one parameter, a string value, is created:
conn:prepare('myselect','select firstname from person where lastname = $1', '')
Now the prepared statement can be used as often as needed using the execPrepared() function, indicating the name of the prepared statement and supplying the actual data values:

At 8.4 x 12.4 micrometers, the world's smallest advent calendar was created in a lab late one night in Germany. The motivation for the work was that the researchers wanted to have "a nice picture of Christmas to put on our homepage."
"We waited until normal business was done for the day in the clean room," said PhD student Daniel Neumaier at the University of Regensburg, one of the three collaborators on the project. "Then we went in and did it. We were just having fun." He said the creation took about two hours.
On the randomly-numbered calendar, the doors for the first six days of December are open, revealing six different images, including Santa Claus, a bell, a snowman and a church. The smallest images on the calendar are the glass panes on the church windows, which measure about 20nm. At the bottom of the calendar, the researchers finished with a wish: "Merry Christmas wish from Nanonic" in German. It would take about 5 million of the calendars to fit on a postage stamp.
Nanonic is the start-up company founded by the three doctoral students, which supplied the computer program that guided an electron microscope in this project. Using the electron microscope, the scientists etched a semiconducting wafer coated with a material called "Poly(methyl methacrylate)" (PMMA). By breaking the bonds of the PMMA, they etched the lines and images on underlying semiconductor. Later they improved the contrast with an ion beam.
One of the collaborators, Dieter Weiss, thinks that the advent calendar is the smallest in the world, but explains that he doesn't know for sure. "I searched on Google and could find nothing smaller," he said.
The researchers admit that other labs around the world could create similar nano-scale images, which are used primarily for scientific research, and not art.

Clinically Appicable Paper. Adherence to sport injury rehabilitation programs: an integrated psycho-social approach
MetadataShow full metadata
Introduction: The Adapted Planned Behaviour Model (APBM) is a two stage psycho-social theoretical model consisting of initiation or decision-making, and maintenance or rehabilitation behaviours. The initiation phase includes the primary factors of threat appraisals (perceived severity and susceptibility), goal orientation (learning goal and performance goal orientation) and attitude to the rehabilitation. These five factors directly influence the rehabilitation intentions which in turn influence rehabilitation adherence. Self-efficacy and self-motivation have roles in both the initiation and maintenance phases by influencing intentions and adherence. Rehabilitation adherence is further influenced by behavioural habits and secondary factors of coping ability (distraction, palliative, instrumental and emotional), treatment efficacy and social support (emotion and listening support and task appreciation and personal assistance from other people). Purpose: To test the ability of the APBM to predict rehabilitation intentions and adherence in individuals undertaking sport injury rehabilitation for tendonitis-related overuse injuries. Methods: This was a prospective one-group design in which 70 participants were followed through their rehabilitation. The sample consisted of 44 male and 26 female participants with a mean age of 32.5 years (±10.2), with most of the tendonitis-related overuse injuries being located at the ankle (41%), and lesser numbers at the knee (28%), shoulder (20%) and elbow (11%). Typically, the participants attended two 40 to 60 minute clinic rehabilitation sessions per week for eight to 10 weeks. The rehabilitation protocol consisted of structured progressive exercises and stretching activities, and in the early stages ice, heat and ultrasound were also included. At the beginning of the rehabilitation, participants were measured on self-efficacy, self-motivation, and the primary factors of the APBM (threat appraisals, goal orientation, and attitude to the rehabilitation programme) and rehabilitation intentions. During the rehabilitation attendance at the clinic appointments was recorded, and adherence to the clinicand home-based rehabilitation were measured. At the end of the rehabilitation the behavioural habits and the secondary factors of the APBM (coping ability, social support and treatment efficacy) were measured. Results: Regression analyses tested the ability of the psychosocial variables of the APBM to predict intentions, and the ability of the psycho-social variables and intentions to predict adherence. Intentions were significantly predicted by perceived severity, perceived susceptibility, learning orientation and attitude, but not self-efficacy, self-motivation and performance goal orientations. Clinic attendance was predicted by self-efficacy, self-motivation, intention, palliative coping, treatment efficacy, and personal assistance from the family. Clinic adherence was predicted by selfefficacy, self-motivation, intention, distraction and palliative coping, treatment efficacy and task appreciation by the physiotherapist and emotional support from friends. Homebased adherence was predicted by distraction and palliative coping, habit and task appreciation by the physiotherapist. Conclusion: The findings point to psycho-social variables influencing rehabilitation intentions, clinic attendance and adherence to clinicand home-based rehabilitation in an interactive manner during sport injury rehabilitation.

Trump talk: The secrets behind the president's language
Trump body language composite
Why you can trust Sky News
"Tremendous", "loser", "Sloppy Steve" and "Crooked Hillary" - but what does Mr Trump's use of language reveal about the man?
Ahead of the UK visit, psychologist Dr Peter Collett examines what his chaotic "word salad" might say about the president's intellect.
Donald Trump visits the UK this week
Image: Donald Trump visits the UK this week
The first thing we notice is that Donald Trump's speaking style is casual and informal.
He frequently resorts to familiar words like "folks" and "hombres" in order to buddy-up to his listeners and show that he does not stand on ceremony.
There are two main theories as to why he favours an informal register.
More on Donald Trump
One is a "deficit theory", which points out that Mr Trump's verbal output is often rambling and disjointed.
It consists of a "word salad", where the words are just tossed together.
Exponents of this theory argue that his unruly speech patterns are the product of an unruly mind, and that they show him to be incapable of complex thinking.
A number of studies have confirmed the president's speech is restricted. He tends, for example, to use single-syllable words, and tests reveal that his verbal output is similar to that of a nine or 10-year-old.
However, this only appears to be the case when he is speaking off the cuff.
When he's giving a scripted speech, his verbal fluency is comparable to that of any articulate politician.

Trump Talk: punchy attacks on PC culture
The second explanation is a "difference theory".
Here it is proposed that Mr Trump's casual way of speaking is simply his way of connecting with his audience - in other words, showing his listeners that he is unpretentious and therefore more genuine.
His word choice provides a fascinating window into his thinking.
For example, the range of words he uses to signal his approval is unusually narrow - typically, people or things are either "beautiful" or "tremendous".
In contrast, his lexicon of disapproval is rich and varied.
It includes famous descriptions like "Crooked Hillary", "Lyin' Ted", "low-energy Jeb" and "Sloppy Steve", not to mention his all-purpose put-down - "loser".

Trump Talk: Using sales spin to win you over
President Trump's linguistic focus is therefore very much on people's negative, rather than their positive qualities.
The fact that he uses extreme language when describing people and things has encouraged the idea that he is susceptible to what psychologists call "dichotomous thinking".
In other words, that he sees the world in black or white, good or bad, us versus them; that there is no shading in between and no subtlety.
In fact, this is not entirely the case, because Trump will often use expressions like "good man" or "good guy" when he is referring to someone from whom he is trying to distance himself, or whom he does not rate highly.
It is his way of appearing to be supportive, while damning the person with faint praise.
Mr Trump's verbal output also includes other coded messages. He frequently attacks "political correctness", for example.
This pretends to champion the cause of free speech, but its real purpose is to inform his followers that it is quite in order to entertain racist, sexist or antisocial attitudes.
The most important clue to his speech style is the fact that that he loves striking deals.
Whether he's at a rally, being interviewed, or talking to the press, he is constantly pitching to his customers.
He parades his credentials, he recounts the glowing endorsements he has received, he slags off his competitors, and he never fails to produce an entertaining and engaging spectacle.
For President Trump, politics is all about the art of the deal, and, in his case, the art of the big deal.

The Gun Facts project maintains a database of U.S. mass public shootings (MPSs). This database uses the original criminology definition of MPS: four or more people are killed in a single location, not including attackers.
The Gun Facts MPS database has two elements that were first found in this database (though other researchers have replicated our efforts). This includes:
 1. Determining if any of the weapons used conformed to the 1994 Federal Assault Weapons Ban criteria.
 2. If the event was a "cattle pen scenario", which is a unique Gun facts observation about what makes MPSs more deadly.
We have also incorporated data from The Violence Project database (e.g. if events were planned).

I want to know methods which are fully parallelizable on CUDA architecture. I have implemented the Jacobi and Conjugate Gradient methods and now Im thinking about the Bi-Conjugate gradient method. I was using the cublas library to simplify some basic algebra operations. Someone said me that Gauss-Seidel is semi-parallelizable. I am new on CUDA, so I cannot understand some issues in the Cholesky descomposition or Gaussian-Elimination papers like:
I can't understand the new algorithms, so I am saying that I have to use the classic numerical algorithms(I am not able to "create" that kind of algorithms), something like.
The point is, does there exist any "theory" about parallelizing of those algorithms? Because it was easy for me the Jacobi parallelization and conjugate gradient methods, there was some saxpy and gemv operations inside the algorithms.
For example in the Cholesky's case the inner loop depends of the first, how we can solve this?
for k = 1 to n... for j = k + 1 to n
PS: I always developed the algorithms on C++ and from there I started to parallelizing process( it means the process of "discovering" how to parallelize )

Change-aware scheduling for effectively updating linked open data caches
Akhtar, U and Razzaq, MA and Ur Rehman, U and Amin, MB and Khan, WA and Huh, E-N and Lee, S, Change-aware scheduling for effectively updating linked open data caches, IEEE Access, 6 pp. 65862-65873. ISSN 2169-3536 (2018) [Refereed Article]
The linked open data (LOD) cloud is a global information space with a wealth of structured facts, which are useful for a wide range of usage scenarios. The LOD cloud handles a large number of requests from applications consuming the data. However, the performance of retrieving data from LOD repositories is one of the major challenge. Overcome with this challenge, we argue that it is advantageous to maintain a local cache for efficient querying and processing. Due to the continuous evolution of the LOD cloud, local copies become outdated. In order to utilize the best resources, improvised scheduling is required to maintain the freshness of the local data cache. In this paper, we have proposed an approach to efficiently capture the changes and update the cache. Our proposed approach, called application-aware change prioritization (AACP), consists of a change metric that quantifies the changes in LOD, and a weight function that assigns importance to recent changes. We have also proposed a mechanism to update policies, called preference-aware source update (PASU), which incorporates the previous estimation of changes and establishes when the local data cache needs to be updated. In the experimental evaluation, several state-of-the-art strategies are compared against the proposed approach. The performance of each policy is measured by computing the precision and recall between the local data cache update using the policy under consideration and the data source, which is the ground truth. Both cases of a single update and iterative update are evaluated in this study. The proposed approach is reported to outperform all the other policies by achieving an F1-score of 88% and effectivity of 93.5%.


Two Tribes (and other DevOps Myths)
"When two tribes go to war, a point is all that you can score" – Two Tribes, Frankie Goes To Hollywood.
DevOps, like Agile and Lean before it, is often heavily resisted by established companies struggling to accept that traditional ways of working are not necessarily effective in today's constantly changing world.
I've heard many explanations for why organisations are unwilling to adopt a DevOps model or practices, often based on incorrect assumptions. In this article, I'll debunk some of the common myths about DevOps; my vision is to empower change agents to challenge erroneous beliefs within their organisations and encourage them to reconsider taking a DevOps approach.
Myth #1 DevOps creates a Two Tribes mentality
In the Agile world, we have adopted 'tribe' or 'guild' vernacular to describe modern cross-functional teams that can make decisions locally to improve their effectiveness. These aren't the tribes I'm referring to.
In traditional IT, the plan – build – operate model has created a disconnect between the development team (the people who build the software) and operations (the people responsible for looking after the software in production). These two tribes are often at war. Historically, poor implementation of IT Infrastructure Library processes has created strong demarcation between these two functions and negatively affected the flow of working software into the production environment.
The level of mistrust between these two groups is high.
Operations teams are concerned that in a highly complex environment (and under business pressure to deliver), development teams will put technical debt into production for operations to support — an "all care, no responsibility" approach to software development. On the other side of the coin, the development teams are frustrated by the time it takes to make configuration changes, open up firewall rules and deploy their applications.
Often, the mention of DevOps as a way to solve these problems leads to paranoia that each team's special skills will be eroded. In fact, nothing could be further from the truth. DevOps supports cross-team collaboration, encouraging both teams to work together to address each other's concerns about quality software being deployed.
Puppet's 2016 State of DevOps Report provided key metrics around IT and organisational performance.
Puppet's report showed that teams that adopt DevOps principles realise a 22% decrease in unplanned work and rework.
Myth #2 DevOps adds risk with continuous delivery
I remember the pre-Agile days in IT when there was a single release of software at the end of a project. People had to cancel their leave around the go live date, and everybody was expected to work an entire weekend. The whole event was very stressful and failure was not an option.
In almost every other pursuit in life, if something is this risky then the smart thing to do is to practice it. Strangely, suggesting this approach in a traditional IT organisation is usually met with shock, mainly because most deployment processes are poorly implemented.
A well-crafted delivery pipeline has all of the governance processes built in, reducing the risk of deployment and application. DevOps adds value throughout the entire software creation process, using a combination of Agile and Lean techniques to ensure that the software is of a high standard, its functionality delivers the highest value to the customer, and its passage into the production environment is low risk.
Puppet found that DevOps teams report a 3X reduction in change failure rates and a 24X faster recovery from failure rate than traditional IT environments.
Myth #3 DevOps is just another excuse for IT to spend money on tools
It's true that if you store your infrastructure as code, automate all of your tests and monitor all of your environments, you'll have to invest in technology to enable this, but it doesn't need to cost a lot of money. In fact, almost everything that you need to enable DevOps is open source.
Some organisations choose to pay for product support for commercial products, however this investment represents a fraction of the value that a 2000X improvement in lead time can give an organisation.
Myth #4 DevOps creates a security nightmare
Complex environments generate threats to an organisation's security. Migration to offsite infrastructure, creating consistent-looking environments and sharing enterprise space (as per the practice of Continuous Integration) have all created opportunities for hackers to infiltrate an organisation's technology platforms.
The establishment of infrastructure-as-code, multiple deployments a day and giving developers access to production environments are looked at as security risks, and often used to justify resistance to the adoption of DevOps practices by many organisations.
According to the latest data, DevOps adopters spend 50% less time remediating security issues than others, because their information security objectives are integrated into their daily work.
Myth #5 DevOps is all about release management
Release management is undoubtedly an important component of DevOps. Unless you can safely deploy your code into the production environment and into the hands of your users, your organisation is not banking the value that your software delivers. However, it's important to acknowledge that there's more to DevOps than release management.
If your code is fragile and you have no way of automatically verifying the software's quality, users will not find it useful if it's riddled with defects, regardless of how safely the code was shepherded into production.
DevOps encapsulates good software practices including architectural decisions to reduce batch sizes, and a quality first approach to writing software to ensure clean, organised and maintainable code. Testing should be optimised for automation so that quality can be assured before software is deployed.
Automated builds, testing, deployment and provisioning provide consistency when moving software into environments, increasing speed and reducing risks.
Why DevOps does not create a two tribes mentality
As you can see, there are still a lot of myths surrounding what is DevOps. This blog aims to explain that DevOps is more than just release management, encapsulating software architecture and quality assurance as well.
It's also a risk mitigation strategy that enhances your capability for consistency and security and most importantly, creates an opportunity for people to align and collaborate to reach a common goal.
DevOps lowers the cost of the transaction of getting into the production environment which enables small and frequent changes. This aspect supports faster delivery and unlocks customer value as more regular releases allow the organisation to respond to feedback and tailor changes to deliver even higher levels of customer satisfaction.

Motion of no confidence
From Wikipedia, the free encyclopedia
 (Redirected from Vote of confidence)
Jump to: navigation, search
A motion of no confidence (alternatively vote of no confidence, censure motion, no-confidence motion, or (unsuccessful) confidence motion) is a statement or vote that a person or persons in a position of responsibility (government, managerial, etc.) is no longer deemed fit to hold that position: perhaps because they are inadequate in some respect, are failing to carry out obligations, or are making decisions that other members feel are detrimental. As a parliamentary motion, it demonstrates to the head of state that the elected parliament no longer has confidence in (one or more members of) the appointed government.
A censure motion is different from a no-confidence motion. Depending on the constitution of the body concerned, "No Confidence" may lead to compulsory resignation of the council of ministers or other position-holder(s), whereas "Censure" is meant to show disapproval and does not result in the resignation of ministers. The censure motion can be against an individual minister or a group of ministers, but the no-confidence motion is directed against the entire cabinet. Again, depending on the applicable rules, censure motions may need to state the reasons for the motion while no-confidence motions may not require reasons to be specified.
Parliamentary systems[edit]
In many parliamentary democracies, strict time limits exist as to the proposal of a no confidence motion, with a vote only allowed once every three, four or six months. Thus the timing of a motion of no confidence is a matter of political judgement; using a motion of no confidence on a relatively trivial matter may prove counterproductive if a more important issue suddenly arises which warrants a motion of no confidence, because a motion cannot be proposed if one had been voted on recently. Sometimes, the government will choose to declare that one of its bills is a "motion of confidence" in order to prevent dissident members of parliament from voting against it.
United Kingdom[edit]
Traditionally, in the Westminster system, the defeat of a supply bill (one that concerns the spending of money) is seen to require the resignation of the government or dissolution of Parliament, much like a non-confidence vote, since a government that cannot spend money is hamstrung, also called loss of supply. When the upper house of a Westminster system country has the right to refuse supply, such as in Australia during the events of 1975, the convention is in a grey area, as Westminster governments are not normally expected to maintain the confidence of the upper house.
Prior to 2011, in the British Parliament, a no-confidence motion generally first appeared as an early day motion, although the vote on the Queen's Speech also constituted a confidence motion.[1] However, under the Fixed-term Parliaments Act 2011, only a motion explicitly resolving "That this House has no confidence in Her Majesty's Government" is treated as a motion of no confidence.
In India, a Motion of No Confidence can be introduced only in the Lok Sabha (the lower house of the Parliament of India). The motion is admitted for discussion when a minimum of fifty members of the house support the motion.[2] If the motion carries, the house debates and votes on the motion. If a majority of the members of the house vote in favour of the motion, the motion is passed and the Government is bound to vacate the office. Acharya Kripalani moved the first-ever No confidence motion on the floor of the Lok Sabha in August 1963, immediately after the disastrous India-China War.[3][4]
In Italy,[5] the government requires the support of both houses of the Parliament. A vote of no confidence may be proposed if one tenth of the members of a single house sign the proposition and starting from three days before the appointed date, said vote can be brought into discussion. Following the case of Filippo Mancuso in 1995 and the subsequent Constitutional Court sentence in 1996,[6] it is possible to propose an individual vote of no confidence against a single minister instead of the whole government.
In the Australian Parliament, a motion of no-confidence requires a majority of the members present in the House of Representatives to agree to it. The House of Representatives currently consists of 150 members; requiring 76 votes in favour of the motion when all members of the House are present. A vote of no confidence in a Government, or a motion or amendment censuring a Government, has never been successful in the House of Representatives.[10] Despite this, on eight occasions Governments have either resigned or advised a dissolution following their defeat on other questions before the House. Specific motions of no confidence or censure motions against the Prime Minister, ministers, the Leader of the Opposition, Senators and leaders of political parties have been moved and have been successful on some occasions. Motions of no confidence against the Government may be passed in the Senate, yet may have little or no impact in the House.[10]
Presidential systems[edit]
United States[edit]
In the United States, motions styled as "no confidence" are only symbolic and are rare. Party leadership turnover generally occurs as a result of internal discussion and vote among the elected members of the party, followed by the response of the public in a primary election and general election.
In organizations that use Robert's Rules of Order Newly Revised (RONR), there is no motion of no confidence, although the assembly could adopt a motion expressing a lack of confidence in its leaders (i.e. a motion to censure).[11]
The United States Congress passed a no confidence motion against Secretary of State Dean Acheson in the 1950s[12] and considered one against Attorney General Alberto Gonzales,[13] but these motions are of symbolic effect only.
Removal from office[edit]
As U.S. political tradition does not include motions of no confidence, laws provide for the removal of specific people. All of these processes are designed to be rare.
In some U.S. states, a recall election fills a similar role of removing an unpopular executive officer, but in contrast to a motion of no confidence, a recall vote is a no-confidence election by the public and is normally only allowed against elected executive offices, rather than legislative seats. In states that have recall elections, the law usually restricts how often they are held, so that recall attempts do not follow each highly contested election.
Each house of Congress may, by a two-thirds majority, vote to expel any of its own members, and similar processes exist in U.S. state legislatures. These removals are very rare, and the motivations are typically criminal misdeeds or ethics violations, not mere loss of confidence.
Impeachment in the United States can remove a government officer through a two-part process in the legislature. Congress can remove a federal officer, including the President and any federal judge. State legislatures have similar powers over the state offices. Impeachment is reserved for criminal conduct or major ethical violations and is not directly a vote of no confidence in the party, since removal of the head of government usually results in succession by an officer of the same party.
To deal with this situation, the French placed a great degree of executive power in the office of its President, who is immune from Motions of No Confidence.

May 4, 2005Scientists say that they've proved that the tall
erect spike grown by the South African plant Babiana ringens
has a single purpose: It is a perch for birds, making it easier for
them to drink nectar from the plant's peculiar ground-level flowers.
The perch allows the malachite sunbird, the plant's main pollinator, to insert its curved beak into the flowers from above. When a bird assumes the upside-down position, its breast is brushed with pollen. The bird then spreads the pollen to other B. ringens (commonly known as rat's tails), thereby cross-pollinating the plant species.
Reporting in tomorrow's issue of the science journal Nature, researchers said that when they removed the perch, it decreased the mating success of the plant because significantly fewer sunbirds came to drink nectar. Male sunbirds were particularly less inclined to visit a plant that did not have a perch, possibly because they have much longer tail feathers, which could interfere with ground landings and takeoffs.
The research was done by Spencer C. H. Barrett of the University of Toronto, Canada, and Bruce Anderson of the University of KwaZulu-Natal, Scottsville, South Africa.

"Districts should provide targeted support to improve practices within schools, and ensure communication and information sharing between authorities and schools. Schools need to share best practice." National Planning Commission: National Development Plan, November 2011.
An education district office is the sub-structure of a Provincial Education Department (PED) immediately below the provincial head office. It represents and exercises the authority of the PED in all day-to-day administrative and professional dealings with schools and ECD centres. It is the public face of the PED in its district area. It delivers services to the education institutions for which it is responsible in its area.
Education district offices have a pivotal role in ensuring that all learners have access to education of progressively high quality, since district offices are the link between provincial education departments, their education institutions and the public.

Mold needs two things to survive and spread: moisture and food. Because it's susceptible to moisture, traditional paper-faced drywall is mold's favorite sandwich, with two outer faces of paper as the bread and the gypsum stuck in the middle as baloney. Gypsum is a mineral, and though mold cannot digest it, the cellulose in the paper can be degraded by some molds. The drywall paper is like bread in another way: the paper contains up to one percent starch, another nutrient for mold.
A great alternative to traditional, paper-faced drywall is Georgia-Pacific's DensArmor® Plus, a relatively new type of drywall in which the paper faces have been replaced by thin, fiberglass mats. It's moisture-resistant, and because fiberglass, like gypsum, is a mineral, there are no nutrients on which the mold can grow.

User-defined plugins
Siconos proposes a 'plugin' system that allows users to provide their own function(s) to describe some specific behavior for some classes components.
For example, consider a lagrangian linear dynamical system, where \(M\ddot q + C \dot q + K q = F_{Ext}(t,z) + p\).
Suppose you want to set \(F_{Ext}(t,z) = cos(t)\), then you can define a C function to compute this cosine and 'plug' it to the dynamical system so that each time the system needs to compute its external forces, your cosine function will be called.
At the time, plug-in are available for DynamicalSystems and Relation. For both of them and for their derived classes, a list of the variables that can be plugged is given in ds_plugins and relation_plugins.
 - find the variable you want to plug and check what is the expected list of arguments for a function plugged to this variable (check ds_plugins or relation_plugins).
 - write a C function:
 extern "C" external_forces(double time, int size, double* fext, int zsize, double *z)
 (*fext)(i) = cos(time);
 - connect your function to the variable. For each 'plugable' variable, a setComputeVARNAMEFunction exists
ds->setComputeFExtFunction('myPlugin', 'external_forces');
//...
// --> call external_forces with time == 2.
Plugins overview
plugins in siconos classes
Class Name
plugin name
\(g(\dot x, x, t, z)\)
(double time, int x_size, double *x, int lambda_size, double * lambda, double * y, int z_size, double * z)
Suppose that you defined a LagrangianDS named lds, and want to set two parameters in the external forces, say mu and lambda.
Then cpp input file looks like:
// In the main file:
double mu, lambda;
//... give mu and lambda the required values
//... declare and built your dynamical system
SP::DynamicalSystem lds(new LagrangianDS(...));
// Link with the plug-in function
lds->setComputeFExtFunction("", "myFExt");
// === First way, with setZ function (copy) ===
// declare and built a SimpleVector of size 2
SimpleVector myZ(2);
myZ(0) = mu;
myZ(1) = lambda;
// In this case, if parameters values are change after this step,
// this won't affect param values inside the dynamical system.
//=== Second way, with setZPtr function (pointer link) ===
// declare and built a pointer to SimpleVector of size 2
SP::SimpleVector myZPtr(new SimpleVector(2));
(*myZPtr)(0) = mu;
(*myZPtr)(1) = lambda;
// Warning: in that case, from this point any change in parameters
// will affect param value in the dynamical system.
// Then in the plug-in file, you have access to the parameter values:
extern "C" void myFExt(double time, unsigned int sizeOfq, double *fExt, unsigned int sizeOfZ, double *z)
for(unsigned int i = 0; i

Biketastic: Sensing and Mapping for Better Biking [Conference Paper]
NESL Technical Report #: 2010-1-1
Abstract: Bicycling is an affordable, environmentally friendly alternative transportation mode to motorized travel. A common task performed by bikers is to find good routes in an area, where the quality of a route is based on safety, efficiency, and enjoyment. Finding routes involves trial and error as well as exchanging information between members of a bike community. Biketastic is a platform that enriches this experimentation and route sharing process making it both easier and more effective. Using a mobile phone application and online map visualization, bikers are able to document and share routes, ride statistics, sensed information to infer route roughness and noisiness, and media that documents ride experience. Biketastic was designed to ensure the link between information gathering, visualization, and bicycling practices. In this paper, we present architecture and algorithms for route data inferences and visualization. We evaluate the system based on feedback from bicyclists provided during a two-week pilot.

Straw Bale Construction/Techniques/Pushing the Limit
Pushing the Limit
(Please help us write this section, you could use the following links to get started.)
Arches and vaults
Designing the catenary arch
A _URL_ catenary shape helps you build the sturdiest vault construction. See _URL_ for a basic explanation.
The gravity approach
You will need:
- a heavy rope at least as long as the circumference of your arch (thin metal wire rope would be ideal)
- an even, rectangular wall at least as high and wide as the arch you want to build. Hint: you can make one out of plywood, pallets or anything you want.
- screws and a screwdriver (or nails and a hammer)
- a wide roll of paper
- a spirit level
- spray paint
- If you haven't got the required wall, build one from lightweight materials. Just make sure it's perfectly vertical and level.
- Tape the paper to the wall. Hints: Vertical is easier. Have them overlap a few centimeters. Number the segments.
- Mark a level line on the paper a bit higher than the arch you want to build. Double check the line is level.
- Mark a second line on the paper exactly as far down as the height of the arch you want to build.
- Mark two points on the top line as far apart as the width of the arch you want to build.
- Fix the rope to one nail, as close to the paper as possible. Lower it from the other nail until it reaches the base line.
- Spray paint the rope. Hint: You may also want to quickly spray paint the overlap between paper rolls.
The mathematical approach
You will need: a computer, a pencil, some exact measuring skills, a roll of paper, a long measuring device, adhesive tape, a flat surface the size of your arc.
- Calculate the coordinates of your catenary. You can either use a catenary designer like _URL_ or _URL_ or use the cosh(x) function yourself.
- Tape the paper together to form a big paper surface that could cover the entire catenary's surface.
- Start out by setting out the triangle defined by the top and the two base points of the catenary.
- Precisely mark the coordinates of one point every 50 cm approximately. Keep in mind that the precision of this drawing is key to the stability of your vault, so take your time.
Building the formwork
You will need:
- planks. They don't need to be thick, but they do need to be high.
- a saw (a circular saw will work best, but a hand saw will do)
- nails and a hammer or (preferably) screws and an electric screwdriver
- your catenary arch design
- straw bales (if available)
Let's start building the arches:
- Put the paper arch design on a flat and dry surface (the floor?).
- Put the planks on the inside of the arch design. You will have to saw the planks a bit for this, especially at the top.
- Put a second layer of planks on top of the first one. Screw them to the first layer. The idea is to have them overlap with the first layer to get some basic rigidity.
- Mark every 25cm on the outside of the arch. This is where the horizontal battens will link the three arches.
- Reinforce the arch by screwing two planks in an X shape to the inside of the arch. These should also make carrying the final formwork easier.
- Build three arches by repeating the above steps three times. The arches should be almost identical in shape.
- Measure the length of your bales.
- Space your three arches with a distance of one bale's length between each arch.
- Hint: In some cases it might be easy to: lay the first arch on a flat and dry surface, put bales on top as spacers (keep the length side vertical), lay the second arch on top of that, lay another row of bales, lay the third arch.
- Triple check the arches are all 100% level and perfectly aligned.
- Screw the battens to the three arches, removing any spacer bales as you proceed.
This is how the final formwork might look: _URL_
- _URL_ Vaulted Strawbale Workshops, Instruction Booklets, Tours and more
- _URL_ (good example of a catenary formwork)

The Tiger Who Came To Tea Card Game
The Tiger Who Came To Tea Card Game
Quantity Required:
The Tiger Who Came To Tea Memory Card Game
The classic game of pairs with a twist.
To start shuffle the cards and place face down on a large surface. The youngest player goes first and turns over two cards and shows the other players what's on them. If it's a matching pair they keep them, if not the cards are turned back over in their original place. Play continues to the next person on the player's left. The key to success is remembering where the different cards are so you can select a matching pair when it's your turn. Here's the twist - if a player picks up a card with Dad walking in the door shouting 'I'm Home', the player shouts 'I'm Home' and all the cards have to be shuffled around so no-one knows where each of the cards are.
The Tiger Who Came to Tea Memory Card Game features 54 jumbo cards beautifully illustrated with scenes from Judith Kerr's classic children's storybook.
Not Suitable for children under 3 years.

THE PROTECTIVE STYLE QUESTIONNAIRE: SELFPROTECTIVE MECHANISMS AMONG STIGMATIZED ADOLESCENTS
Crocker and Major (1989) hypothesized three mechanisms by which members of stigmatized groups may protect self-esteem. The mechanisms are: a) ingroup social comparisons, b) valuing/devaluing performance selectively, and c) racial prejudice. We provide a test of Crocker and Major's hypothesized mechanisms with the development of the Protective Style Questionnaire which was administered to a sample of 78 African-American adolescents. Evidence of high internal consistency reliability (about.86) and factor loadings support the orthogonality of the three mechanisms. Results showed varying levels of endorsement of each mechanism.

Ethereum Hashrate Chart
The Ethereum hashrate chart provides the current Ethereum hashrate history in graph format with an option to expand the Ethereum global hashrate chart time frame back to 2016.
Ethereum Hashrate Now: 310.15 TH/s

Loading Ethereum network hashrate chart Loading Ethereum network hashrate chart
The Ethereum network hashrate chart can be used to visualize Ethereum mining hashrate increases and decreases viewable in segment options of daily, weekly, monthly, 3 months, 6 months, 1 year, 3 years, and all time.
What is Ethereum Hashrate?
Ethereum hashrate is a calculated numerical value that specifies an estimate of how many hashes are being generated by Ethereum miners trying to solve the current Ethereum block or any given block.
Ethereum hashrate is represented in Hashes per Second or H/s.
The global Ethereum network hashrate is a calculated value and is measured in hashes per second (H/s). The calculation uses the current mining difficulty and the average Ethereum block time between mined blocks versus the defined block time as variables to determine the global Ethereum network hashrate.
As the Ethereum network hashrate goes up - the ETH hashrate numbers get so large that abbreviations must be used.
The current Ethereum hashrate is 310.15 TH/s, representing the global Ethereum network hashrate with a mining difficulty of 3.72 P at block height 11,359,735.
View the Ethereum hashrate chart for all time historical hashrates.

YH/s (YottaHash) 1,000,000,000,000,000,000,000,000 One Septillion
It is important to point out the Ethereum hashrate does not determine how quickly or slowly each block is solved.
This timing, called the block time is enforced by the Ethereum mining difficulty value, which is adjusted upwards or downwards during each block difficulty retarget to keep blocks being solved at a constant time frame.
For more information about the Ethereum difficulty re-target visit the Ethereum mining page.
You can calculate Ethereum mining profits using the current ETH hashrate difficulty and our Ethereum mining calculator.
What is the Current Ethereum Hashrate?
The current Ethereum hashrate (ETH hashrate) is 310.15 TH/s at block height 11,359,735 with a difficulty of 3,721,852,768,261,272.00.

How to Calculate Ethereum Hashrate
The Ethereum hashrate is calculated using the current Ethereum difficulty, the defined Ethereum block time, and the average block time of the last (X) number of blocks.
Most full Ethereum nodes will have an option to see the current Ethereum global hashrate using the "getnetworkhashps" command in the console window.

Given the fact that the Ethereum difficulty value determines statically how many hashes are needed to solve the next block, it is recommended to use the current mining difficulty to determine the statistically accurate number of Ethereum that can be mined in a given time frame.
Once again we recommend using our Ethereum mining calculator as the current Ethereum difficulty is preloaded, along with the latest Ethereum price.

So there does exist a document already on this topic, Getting OCLC numbers into your vendor records using MarcEdit but I found the instructions difficult to refer to. I ended up writing my own version with the added instructions on creating a set of MARC records specifically for this purpose. After doing this sort of thing again today, I finally decided to share them.
Once you do this once or twice, you'll get a hang of it, and it's actually a fairly simple process, but I always need a reference in case I forget things.
Create a Mini MARC set
The example in the document I referred to talks about merging two existing sets of records. The records I work with typically have the control number in a spreadsheet with some of the item's information (title, author, ISBN, etc.), so the first step is to actually create a set of MARC records with the minimal information needed to merge the control numbers into the main set of MARC records.
To create the mini set of MARC with control numbers, you will need a match point. In the vendor records I've been working with, the match point is the ISBN (020). MarcEdit also gives you 010, 022, and 035 as default options, and you can customize it to a certain extent.
- Do your work with data in a spreadsheet and make sure you have at a minimum your control number in a column, and match point in a second column (order does not matter). I suggest title as well simply for reference.
- Save as Tab Delimited Text (.txt)
- In MarcEdit, choose Delimited Text Translator (also under Add-ins).
- Source file is your tab delimited.txt
- Output to a filename of your choice
- Map each field to its appropriate field. For example,
- 020$a for ISBN
- 035$a for control number column
- 245$a for title
- Run it.
You should now have your mini set of MARC records with minimal information for merging purposes. Do take a quick look over to check that everything is there.
Merge into MARC record set
You should now have two sets of records, your mini set and your main set that you want to add control numbers to.
- Choose Tools → Merge Records
- For Source File, select your main MARC records set
- For Merge File, select the mini MARC set you created
- Set your output file to your desired location and filename
- Choose record identifier e.g. 020 to match on ISBN
- Click on Next
- Choose Merge Selected Fields
- Select the field fields you want to import e.g. 035 (control number)
- Click on Next
Review the output to make sure they were merged properly, and that's it.

Garlic prevents gastric cancer
Font size: Decrease font Enlarge font
Tuesday March 31, 2015 (foodconsumer.org) -- A new study published this year in Nutrition and Cancer suggests that eating garlic may reduce the risk of gastric cancer or stomach cancer.
Epidemiological studies performed in the past two decades indicated that garlic may positively modify the risk of gastric cancer. This may not be surprising considering that some compounds in garlic such as diallyl trisulfide are known to have anticarcinogenic properties.
The new meta-analysis of data from 14 case control studies and two randomized controlled studies and 1 cohort study showed that garlic consumption was associated with reduced risk of gastric cancer.
The highest intake of garlic was found associated with 50% reduction in the risk of gastric cancer, compared to lower intake, and consumption of any amount was linked to about 25% reduced risk, compared to non-consumption.
About 60% of gastric cancer cases are caused by bacteria called Helicobacter pylori. Nearly 50% Asians carry the bacteria. Pickled vegetables, salted or preserved fish and smoking can also increase the risk of the cancer. Eating red meat has also been associated with increased risk of gastric cancer.
H. Pylori can be eliminated by antibiotics. Low intake of salt is another effective preventative against the development of gastric cancer. Studies show that the bacteria produce carcinogens only in a high-salt environment which also explains why pickled vegetables and salted fish (high salt foods) increase the risk.
In addition to garlic, soy, mushroom, Mediterranean diet, and phytochemicals found in fruit and vegetables can also reduce the risk of gastric cancer. (David Liu, Ph.D.)

Tags: Time Period Tags
The purpose of tags is to make information relatively easy to find. The purpose of this essay is, firstly, to explain how I'm using the tags for general eras. The second purpose is to provide a tag list that the visitor can use to explore the site. The number of tags used in the project, and the organization into four different categories, doesn't lend itself to a traditional tag-cloud. I'll be setting up one of these tag essays for Place and Time Period tags, and probably multiple topic-specific essays for the Event/Person and Misc. tag-sets.
General Eras
There is little usefulness to providing century-by-century tags for information relating to pre-medieval sources, although sometimes a specific date is available. Any topics falling before the beginning of the Common Era (i.e., the year 1) will be tagged only generally. Later material will be grouped by century unless the coverage is broad and general, or no specific date is given. At the time I'm writing this, the Renaissance and Early Modern tags haven't been used, because a specific date is almost always available for material falling in those periods.
 - Bronze Age: Archaeologically, this era is defined by technology, but consider the tag to indicate roughly 3000-1000 BCE. Generally entries tagged with this will involve art.
 - Classical Era: This tag is used to indicate the eras dominated by Greek and Roman civilization. In regions where those cultures had no influence, consider it to indicate roughly 1000 BCE to the early centuries of the Common Era. If a more specific date in the Common Era is known, that will be used.
 - Post-Roman/Early Medieval: This tag is used when a more specific date isn't available, covering very roughly the first millennium.
 - Medieval (general): This tag is used when a more specific date isn't available covering very roughly the 11-14th centuries.
 - Renaissance (general): The Renaissance is defined differently in different countries, and generally a more specific date will be used. Consider this to cover roughly the 15-16th centuries.
 - Early Modern (general): This tag is used when a more specific date isn't available, but consider it to cover roughly the 17-18th centuries. This tag is unlikely to be used much.
Keep in mind that entries aren't always tagged by time period unless a specific dated document or person is discussed. If you don't seem to be finding anything in a date range, try searching by place or topic instead.

- This solid performance is a consequence of high levels of investment in oil and gas and energy infrastructure projects.
- Notwithstanding the aforementioned power station, it's largely a different story in the energy and utilities construction sector, however.
- However, it isn't stalling altogether and there are still some ongoing construction projects, including in Queensland.

The achievable time resolution of camera-based single-molecule detection is often limited by the frame rate of the camera. Especially in experiments utilizing single-molecule Förster resonance energy transfer (smFRET) to probe conformational dynamics of biomolecules, increasing the frame rate by either pixel-binning or cropping the field of view decreases the number of molecules that can be monitored simultaneously. Here, we present a generalised excitation scheme termed stroboscopic alternating-laser excitation (sALEX) that significantly improves the time resolution without sacrificing highly parallelised detection in total internal reflection fluorescence (TIRF) microscopy. In addition, we adapt a technique known from diffusion-based confocal microscopy to analyse the complex shape of FRET efficiency histograms. We apply both sALEX and dynamic probability distribution analysis (dPDA) to resolve conformational dynamics of interconverting DNA hairpins in the millisecond time range.

Its festive season, Christmas and New Year is the season of Hope and Happiness, it's time to spread happiness and celebrate the joy of giving! At a time, when there is so much hatred around in the world, unrest, it's necessary to teach our children to be compassionate towards one another. At VIBGYOR, we start sensitising our students about various social concerns at an early age to help them become sensible future citizens of the world.
To spread a smile and share the joy of the festive season, VIBGYOR Rise students visited "AaS" (Awareness to the Society) orphanage this week. The visit was conducted as a part of 'Celebrate the Joy of Sharing' activity. Our students donated stationery items, books, blankets, toys, cloths, etc. to the children. VIBGYOR staff guided children at Aas about "Importance of Sport's in Life" and "Reduce the use of single-use plastic".
Children of "Aas orphanage" welcomed VIBGYOR students with a smile. The atmosphere was fun-filled and joyous as everyone warmed up to each other. The students interacted with each other and shared their experiences.
Principal, Dr. Abhishek Sharma said, "It is not the gift but the thought that counts. On a Christmas Eve, every child wishes for a gift from Santa. This was a chance for our students to be the Santa for a cause. Students are extremely happy after spending time with the kids of "Aas Orphanage". This activity was aimed at inspiring one and all to give in whatever way they choose and to celebrate the feeling of giving. At VIBGYOR, we start sensitising our students at an early age about various social concerns and their surroundings."

Seismic data denoising via shearlet transform and data‐driven tight frame
We propose a sort of double sparsity dictionary (DSD) to deal with random noise of seismic exploration, which consists of shearlet transform and data‐driven tight frame (DDTF). We train the DDTF dictionary in the domain of shearlet transform to improve the robustness of the dictionary. Furthermore, the function of hard‐thresholding is applied to find dictionary coefficients and cut small shearlet coefficients. Finally, we verified the reliability of the proposed approach by a synthetic data denoising example.
