Assault course
From Wikipedia, the free encyclopedia
Jump to: navigation, search
An assault course (also called trim trail) is a special sort of trail that combines running and exercising. It was more popular in the 1970s than it is now.[original research?] It is heavily used in military training. The prime use is to evaluate progress and weaknesses within the team involved.[original research?]
Military training[edit]
Assault courses are used in military training to increase fitness, to demonstrate techniques that can be used for crossing very rough terrain, and to increase teamwork and self-confidence.[original research?]
Often military assault courses will be standardised, and will have, for example (in the UK), a six foot and a ten foot wall, a climbing net, some type of bar to climb over, and a high rope or net that must be crossed (these being or representing the most likely difficult terrain that a soldier will come across). The standardisation means that every course will be to the same quality, though it also means that there will be certain parts that may be familiar if practised.[original research?]
However, they have different purposes. For example, they can be short (less than a minute) with a range on the end (e.g. Junior Leaders, Folkestone), or long (five minutes) as at Thetford.[original research?] This is partially because of space restraints and training objectives. The short one can be run as an individual course and a warmup for the range. The long Thetford course is more of an exercise in endurance and teamwork.
Trim trail[edit]
The term "trim trail" has more recently been applied to a series of wooden exercise stations, scattered in parkland or other locations beside a jogging or walking trail, which can be used to develop balance, strength and coordination.[original research?] They are suitable for both adults and children, and the individual stations have been scientifically designed to provide a range of exercise.[original research?] Most have simple instructions attached to them, and the stations include balance beams, sit-up bars, chin-up bars, parallel bars, and more challenging stations such as pole climbs and ladder walks.[original research?] Bristol City Council have now installed trim trails in six parks, ranging in complexity from Withywood Park, which has a single station, to Victoria Park, which has nine.[1][2] Funding for the trim trail at Hollingworth Lake, in Greater Manchester, which was the idea of the Friends of Hollingworth Lake and opened in August 2010, was provided by the Big Lottery Community Spaces fund.[3]

This paper presents the development technology of standard shielded resistor divider for full lightning impulse voltage. The ability of large-capacity power apparatus to withstand lighting stroke is usually evaluated by means of full lightning impulse voltage. Lightning impulse voltage test has been essential to evaluate the insulation performance of electrical power apparatus. Recently international standard (IEC 60) on high voltage measurement techniques is being revised and requests a formal traceability of high voltage measurements. Therefore, general interest for this area has grown considerably during last years, and several international intercomparisons have already completed worldwide, i.e. Europe, Japan, America etc., In this viewpoint, we have also investigated the step response of the standard shielded resistor divider, which satisfies the IEC recommendation.

Introduction to the hat matrix in regression
What is the Hat matrix (known in econometrics as the projection matrix ) in regression?
The geometry of the Hat matrix in regression.
How does the Hat matrix gets its name?
Interpretation of the Hat matrix in bivariate (simple linear) regression
Having shown my students the geometric interpretation of what the Hat matrix does, I had one student who came stuck after trying to get the picture in his head for the case of a bivariate regression – I could see how he was thinking – and I am sure he is not the only one who gets stuck with this. So let me share with you his question, and resolve it.
Properties of the Hat matrix with proofs
The hat matrix (projection matrix in econometrics) is an orthogonal projection.
Hat matrix is an orthogonal projection
I have yet to explain the difference between a projection, and an orthogonal projection, and this is something I do now. We are interested only in orthogonal projections, not any old projection. I shall explain: difference between these 2 projections; linear algebra properties of these 2 projectionsintuitively why is a projection matrix idempotent? All this is explained using the Hat matrix.
Projection and orthogonal projections
A matrix is a projection matrix if and only if it is idempotent; a matrix is an orthogonal projection if and only if it is symmetric and idempotent.
The idempotent property makes any projection matrix positive semi definite. The symmetric property is used in the proof but isn't required as a condition (if I understand correctly) as the symmetric condition is implicit in the quadratic form, by which I mean that in a quadratic form, x'Ax, even if A is not symmetric it may be written equivalently as a quadratic form with a symmetric matrix, namely:
Because of this when we look at quadratic forms, we can just study the cases for symmetric matrices.
How is it that the Hat matrix projects a vector on to the column space spanned by X?
So we know that a projection matrix is a linear transformation that takes a vector and puts it into the space spanned by the column vectors in the matrix. But the Hat matrix is a function of the Xs. So how can we say that the Hat matrix projects a vector onto the column space spanned by the vectors in matrix X? Shouldn't it be that H projects a vector onto the space spanned by the vectors v, where v s are the vectors in the H matrix? This is something I had been puzzled about – and I would have loved to have heard the explanation in my econometrics classes – something that never happened. (Closest I got to an explanation was in my 2nd year linear algebra class). Sit back and watch while I tell you one of my favourite stories.

text: Strain and Strain rate tensors can be computed from velocity encoded phase contrast imaging. The study of the variation of deformation indices with force output (% Maximum Voluntary Contraction (MVC)) can provide information on the aging muscle. However, such studies have been limited by the long acquisition time precluding its use at high MVCs and in older subjects. We developed a compressed sensing VE-PC technique to enable acquisitions across a range of MVCs and applicable to older subjects as well. Significant differences in the deformation indices were seen between 11 young / 8 senior subjects as well between different %MVCs.

text: The Corte armchair comes from the idea of splitting the volume by segmenting it in slices, hence comes its name. Each one of the sections has a different outline. Side by side, this contours model the curvature of the seat and back. It's as if, slicing the armchair and reassembling its pieces, the chair was one step from both its construction and its deconstruction. It contains the full and the empty: the repetition of its equal and different rims mirrored through the center create a resonance that goes beyond the piece itself, echoing in an imaginary movement.

The Caroline Dormon Trail in Kisatchie National Forest is one of the best ways to access remote wilderness in Louisiana. A point-to-point trail, Caroline Dorman stretches 10.5 miles through beautiful and somewhat rare longleaf pine forest. The trail is named after a botanist and naturalist who was born in 1888. Caroline Dorman was the first to propose the creation of the Louisiana State Arboretum, which was the first state-supported arboretum of its kind. She also helped spearhead the creation and protection of Kisatchie National Forest.
The trail begins almost directly off of the Longleaf Scenic Byway. There is ample parking, including large spaces for trucks with horse trailers. The trail is very well-marked with orange blazes that are clearly displayed on the longleaf pines. The trail has some inclines and declines along the way, but overall it is relatively flat and can be finished rather quickly. Something about hiking through this forest is especially peaceful and quiet, allowing for a good opportunity to do some reflecting.
One of the best ways to see the trail in its entirety is via backpacking. There are several primitive campsites along the trail, or you could push through the entire trail and camp at the opposite end in Kisatchie Bayou Campground. The trail ends at this campground, which is located right next to the Kisatchie Bayou. The sound of rushing water from the bayou is lovely and will help you fall asleep at night. To increase your camping/hiking options in Kisatchie National Forest, you can connect to the Backbone Trail and/or Sandstone Trail to make your backpacking adventure a multi-day experience.
Another attraction in the area is the Longleaf Scenic Byway, which has several points of interest along 17 miles of road. Be sure to stop and check out the view from Longleaf Vista along the byway.

Change-Makers are able to assess their position in any situation, and work to change things so that they are making the most out of their
PVC Activity Suggestions
Facilitator Instructions
1. Create a list of scenarios that your participants may encounter in life and/ or on the program (i.e. "Going on family vacation", "Completing a group project", "Participating in this program")
2. Make three big signs, one each for Prisoner, Vacationer, Leader. Place the signs on three different walls of your program space (or on the floor or ground, depending on space available)
3. Begin the activity by reviewing the PVC model with the participants (using the model displayed on a flipchart or PowerPoint slide). Ask participants to tell you what a mindset is, discuss the meaning of mindset and some common mindsets. Review the PVC model after they understand the meaning of 'mindset'.
4. One at a time, read out your list of prompts and have participants move to the sign that depicts their mindset in each scenario.
5. Once the participants have moved to a sign, you may choose to have them discuss their mindset with the others at that station, or explain their mindset to a group at a different station.
6. You may wish to ask participants what it would take for them to change their mindset in particular situations. Is it possible to change ones mindset in challenging situations? Why or why not?

Overview of a First Payment Reminder Letter
A First Payment Reminder Letter is a short, friendly reminder to repay an outstanding payment from a client or customer.
What are Debt Collection Letters?
Debt Collection Letters are the first step in the debt collection process. In order to recover debt, it is recommended to first issue late payment reminder letters to clients or customers about overdue payments. These are also known as Demand Letters or Letters of Demand.
Why send Debt Recovery Letters?
Debt recovery is a major concern for many small businesses. Late payment reminder letters can be a useful and affordable way of chasing up overdue invoices by prompting a customer to pay the overdue amount. Having a structured credit control process in the collection of debt saves time spent collecting payments and managing cash flow.
What is a First Payment Reminder Letter?
A First Payment Reminder Letter is a short, friendly reminder to repay an outstanding payment from a client or customer. It should be as polite and friendly as possible and professional. It can be sent by any means but it is usually sent by e-mail or postal mail.
What is a Second Payment Reminder Letter?
A Second Payment Reminder Letter serves as a follow up reminder after already issuing a First Payment Reminder Letter, and the tone can be more direct than the first. It helps to minimise the amount of valuable time and effort spent chasing late payments, and serves as part of a structured credit control process. It can be sent by any means but it is usually sent by e-mail or postal mail.
What is a Final Debt Recovery Letter?
Also known as a Letter before Action, a Final Debt Recovery letter is the third and final reminder to pay and outstanding debt. Basically, it is a short, clear demand to repay an outstanding payment. Either, it may or may not, include the mention of pursuing legal action if the debt is not settled. Importantly, it is not a legally binding document and can be re-issued multiple times.
What is the Pre-Action Protocol for Debt Claims?
In the UK, the Ministry of Justice has released requirements with regards to the information and process required in order to claim payment of debt from an individual or sole trader before court proceedings can be issued. The Pre-Action Protocol for Debt Claims serves as a good general business debt collection best practice guideline.
What are the requirements of the Pre-Action Protocol for Debt Claims?
In order to satisfy the requirements of the Pre-Action Protocol for Debt Claims, your communications should include:
- Details of the amount owed and the agreement under which this debt originates
- Up to date details of any interest and administrative charges added
- Payment instructions including the method of and address of payment
- Information about payment options available to the debtor
- A Reply Form, Information Sheet, Financial Statement Form, and a reply address for the Reply Form.
Letters should be clearly dated and sent by post unless alternative methods of communication have been explicitly requested.
Does a Letter before Action have to be sent by registered mail?
A First Payment Reminder Letter, or Letter before Action, should be sent by postal mail unless alternative methods of communications have been explicitly requested. However, the gravity and intention of debt collection is communicated with better chance of success if sent by registered mail.
When to send Payment Recovery Letters?
Payment Recovery Letters should be sent when a payment is overdue. A payment is overdue when an outstanding payment is outside the payment terms. If payment terms have not been specified, it is usually customary to consider a payment overdue after 30 days.
What are Payment Terms and Payment Instructions?
In essence, payment terms are the conditions under which a payment should be made. Usually, payment terms include when a payment is expected, any conditions on that payment, and any discounts or penalties relating to the timing of the payment. Subsequently, payment instructions are the means and methods of payment.
What are Common Payment Terms?
Essentially, parties are free to negotiate the desired payment terms. In practice, the provider of a good or service will normally have standard payment terms. Common payment terms include:
- Payment in Advance
- Or, Net 7 (payment due 7 days after invoice date)
- Net 30 (payment due 30 days after invoice date)
- Or, Net 60 (payment due 60 days after invoice date)
What is the difference between an Invoice and a Payment Request Letter?
An invoice, also known as a bill, is a commercial document issued by a seller to a buyer requesting payment for the provision of goods or services. It can be issued in advance or afterwards. It usually includes a breakdown of the costs for the goods or services provided, the total amount due, payment instructions, and payment terms.
Conclusion on First Payment Reminder Letters
First Payment Reminder Letters are follow-up communications after an invoice has been sent but no payment received. They are commercial documents part of the debt collection process. Payment Request Letters are the first step if a customer is slow-paying invoices or refusing to pay an invoice.

This comes as the RSS' Asset Recovery Unit (ARU), and its Regional Maritime Officer, collaborated recently to host a two-day workshop for 174 officers across the RSS Member States, including the Barbados Coast Guard PELICAN.
During the exercise, Director of the Asset Recovery Unit, Kisha Sutherland, stated that the RSS ARU operates on the principle that crime does not pay, and pointed out that through the training, soldiers would be made aware of how they can prevent criminals from financially benefitting from their activities.
"Financial crimes, such as illicit trafficking, are done with a profit motive, topics such as money laundering and cash seizure will help to aid in bringing the fight to the criminals," she maintained.
The ARU head stated that it was necessary for all areas of law enforcement to work together to ensure that perpetrators were not successful in their illegal crimes.
"Our work and engagement show that to fight crime effectively, an all-of-law enforcement approach must be embraced and coordinated. This requires building and enhancing capacity in all aspects of law enforcement that touches and concerns the national crime fighting strategy," she pointed out.
The RSS official explained that the training programme was designed for members of the Coast Guards, whom she noted played a major role in maritime interceptions.
"We are cognisant of the limited investigative and law enforcement role played by the Defence Force in these crime interdictions, however, we acknowledge the crucial aspect of its work in being the first responder to an incident and interacting with evidential materials and suspects first hand. This workshop will therefore provide insight on how Coast Guard officers can gather evidence to assist the police and aid in the successful prosecution of cash seizure and money laundering matters," Ms. Sutherland outlined.

Scala Question
Scala: List of vectors to Unique List of items in immutable way
I am receiving list of vectors from some function like
(List(Vector(1), Vector(1, 2), Vector(1, 3), Vector(1, 2, 4), Vector(1, 5)))
I want to convert it into distinct values of integers like
List(1,2,3,4,5)
in Scala using complete immutability.
Please suggest what are the efficient ways to achieve it.
Answer
You can use the flatten and distinct methods on List.
val list = List(Vector(1),
 Vector(1, 2),
 Vector(1, 3),
 Vector(1, 2, 4),
 Vector(1, 5))
val flattened = list.flatten // Gives List(1, 1, 2, 1, 3, 1, 2, 4, 1, 5)
val distinct = flattened.distinct // Gives List(1, 2, 3, 4, 5)

The Efficiency of Reactive Power Compensation of High Power Nonlinear Loads
Keywords:Reactive power, compensation, non-linear load, high power
AbstractThe paper presents and discusses the problems associated with reactive power compensation of nonlinear loads. Analytical results and simulation studies for selected high power drive used in mine when apply dynamic compensation together with active harmonics filters are presented. It was found that application of active power filters allows for compensation high current harmonics in general, and suppression of as reactive power flows as well as current harmonics in the network. On the basis of results conclusions on efficiency of the active on-line compensation of non-linear loads of a high power are formulated.

Ordering Browser Tabs Chronologically to Support Task Continuity
Product teams working on Firefox at Mozilla have long been interested in helping people get things done, whether that's completing homework for school, shopping for a pair of shoes, or doing one's taxes. We are deeply invested in how we can support task continuity, the various steps that people take in getting things done, in our browser products. And we know that in our browsers, tabs play an important role for people carrying out tasks.
Task continuity model
In 2015, Firefox researchers Gemma Petrie and Bill Selman developed a model to explain different types of task continuity strategies, which are represented in the middle of the diagram below.
Task continuity model diagram
Passive strategies include behaviors like leaving a tab open, such as a page for a product that one is considering purchasing. Active strategies include actions like emailing a link, for example a link to a recipe to cook at a later time, to oneself. Share strategies might involve using social media to share content, such as a news article, with other people.
Fast forward to this year and the team working on Firefox for iOS was interested in how we might support task continuity involving leaving tabs open. We continued to see in user research the important role that tabs play in task continuity, and we wanted to explore how to make tab retrieval and overall tab management easier.
In most web browsers on smartphones, tabs are ordered based on when a person first opened them, with the oldest tabs on one end of the interface (top, bottom, left, or right) and the newest tabs stacking to the opposite end of the interface. This ordering logic gets more complex if a new tab is prompted to open when someone taps on a link in an existing tab. A site may be designed to launch links in new tabs or a person may choose to open new tabs for links. The new tab, in that case, typically will open immediately next to the tab where the link was tapped, pushing all other later tabs toward the other end of the interface. All of this gets even trickier when managing more than just a few tabs. This brief demonstration illustrates tab ordering logic in Firefox for iOS before chronological tabs using the example of someone shopping for a food processor.
Based on a trove of user research, the iOS team raised the following question:
Would ordering tabs chronologically in Firefox for iOS make it easier for people to stay organized and feel more in control of their tabs?
The team conducted user research, led by Elisabeth Klann, in April of this year to understand current tab behaviors and to evaluate a basic prototype of the concept of chronological tabs.
A screenshot of the prototype used for the concept evaluation in April 2020, showing a fictional set of open tabs in Firefox for iOS
We recruited 10 adult participants in the US, half of whom were already using Firefox for iOS and half of whom used either Safari or Chrome as their main browser on their iPhone.
What we learned from the first round of user research
From asking participants about their existing behaviors with browser tabs on their phones, the Firefox for iOS team was pleasantly surprised to hear participants describe the order of their tabs in terms of time. Participants fell into three categories in terms of their tab habits:
 - "I keep it clean" when the participant generally tried to avoid clutter and closed individual tabs often
 - "I keep forgetting" when the participant was not conscious of accumulating tabs and typically closed tabs in batches when the experience became cumbersome
 - "I keep tabs open for reference…short term" when the participant was more strategic in leaving tabs open for a few sessions until a task was complete
All participants were able to discern the chronological ordering of tabs in the prototype and reported that the ordering was helpful, particularly the chronological ordering of the most recent tabs. It was important to participants that they be able to delete single tabs and batches of tabs, and we identified an opportunity for making batch deletion more discoverable in the UI. Following this round of user research, the team made numerous changes to the tab design, led by Nicole Weber, which were incorporated into a beta build of Firefox for iOS.
Tab date stamps before and after the concept evaluation
One change made after the concept evaluation was to attach dates to the "Today" and "Yesterday" categories of open tabs and to change the "Older" label to the more specific "Last Week."
Delete tab functionality before and after the concept evaluation
Another change made after the concept evaluation was to make the functionality for deleting a tab easier to access.
Continuing to learn with a beta build in a diary study
With the beta build, an early version of Firefox for iOS with chronological tabs and only available to research participants, the Mozilla team wanted to do another round of user research to understand the perceptions and utility of chronological tabs, this time in the real-world context with participants using their own devices rather than the pre-designed tabs of a prototype. We recruited 10 new participants, adults in Canada and the US and again a mix of people already using Firefox on their iPhones and people using other browsers.
Participants used the beta build of Firefox for iOS with chronological tabs as their primary iPhone browser for three days and answered a brief survey at the end of each of those days about their experience moving between web pages and of Firefox overall. Survey questions included:
 - Did you use Firefox Beta to visit more than one web page today?
 - Thinking about when you moved between tabs you were using today, was there anything particularly easy, difficult, and/or confusing about that?
 - Did you revisit any tabs from yesterday or before yesterday? If so, can you please describe what you were doing and what it was like to revisit that older tab?
After three days, we interviewed participants to discuss their survey responses and overall experience with chronological tabs.
From the second round of user research, we learned that while the chronological order of tabs did not seem to break any workflows, it was the overall design of the tabs themselves — the thumbnail image, page title and/or URL, and date stamp in a list-like format — that made tabs more helpful than existing designs such as the undated, untitled, deck-like tabs in Safari on iPhone. One participant explained that the formatting of the tabs reminded her of tasks she wanted to complete. She said:
"So is it was this layout that kind of nudged me because I was going back to a page. And I was like, oh yeah, I went to that one, too. That's right. And then I went back and did that task."
Another participant also said, in going back to the view of all of his open tabs with the small images, he remembered the shoes he was shopping for the day before and his desire to return to that shopping. He returned to the tab with the shoes during our interview.
Participant C1's open tabs in Firefox Beta, including a tab with a thumbnail of a shoe
There were instances, however, when the proposed design broke. A bug rendered some tabs unintelligible due to thumbnail images not populating. Also, several participants used enlarged text on their devices, a setting we did not anticipate that resulted in truncated tab titles and URLs. Participants for whom thumbnails were not populating and tab titles were truncated had a particularly difficult time discerning tabs. We also identified an opportunity, which we know is also an opportunity in the desktop browser, to make tabs more discernible in situations when a person has multiple tabs that look similar, particularly at thumbnail scale, like several Amazon pages or pages from different retailers all for the same product.
Participant C3's open tabs in Firefox Beta with blank thumbnail images and truncated tab titles and URLs
While we are actively working on fixing the bug related to the thumbnail images, it was nevertheless helpful to learn about situations where the design fell short — the key takeaway being that the different parts of the design, the date stamps, the thumbnail image, the page title, and the URL work in concert to help people remember pages they have visited and the context for those visits.
Next: Setting out to understand if iOS findings carry over to other platforms
The team, led by Ashley Thomas, plans to continue work on chronological tabs, such as investigating how we can make tab meta data populate more reliably and planning user research to evaluate the proposed design on Android, tablets, and desktop. Some of the questions the team is excited to pursue in coming weeks include:
 - Are there ways to improve further the accessibility of the proposed design?
 - Will complex workflows common to larger form factors help us uncover new insights about chronological tabs?
 - Is tab functionality most helpful when it is the same across platforms or might platform-specific designs better support task continuity?
 - Are there other ways of sorting tabs that would support people's workflows?
Thank you to the Firefox for iOS team and the many Mozillians, including people outside of the iOS team, who reviewed and provided valuable feedback on an early draft of this post.

The today will mandate a -recommended fix to install new elevator components on all aircraft that addresses a problem linked to at least two instances of inflight elevator vibrations.
The airworthiness directive (AD 2013-06-05), based on a Boeing service bulletin issued in April 2012, gives operators 60 months to replace left and right elevator tab control mechanisms with pieces with modified attach lugs, or modifying the lug assemblies alone.
Boeing says that two operators reported lug failures, which caused "unwanted elevator freeplay." The manufacturer traced the problem to lug bearings "likely installed such that they may become loose and migrate." The redesigned lug mitigates the problem, Boeing says.
The directive affects 1,096 U.S.-registered 737s, the FAA says in the AD. Compliance costs could be $62,400 per aircraft if the entire elevator mechanism is swapped out or $13,500 if operators just modify the lug assemblies, the FAA estimates.
It is not clear how many operators have complied with Boeing's April bulletin, or how many will opt for the less expensive modifications.
The directive supersedes a previous order from September 2010 that required repetitive inspections of the old-design lugs. The new directive terminates the need for repetitive checks.

Let's say you were building a marketplace and you wanted to take some type of commission for allowing a user to sell a thing on your marketplace....how exactly does that work? Is there some type of template you can use that allows a person to pay you a commission, but then receive the payment for the sale of their item?
I don't know of any template, but this can be done relatively easily with solidity. Consider the dummy code below:
pragma solidity ^0.8.0;
/*your code here*/
// private function because it simply calculates commission and pays out accordingly.
// Inputs & other validation likely will come from somewhere else in the contract.
function takeCommission(address seller, address platform, uint256 amountPaid, uint256 commissionPercentage) private {
 // ensures the minimum amountPaid is at least 100 wei and is accurately divisible
 require(amountPaid % 100 == 0);
 // divide by 100 because commission percentage is expressed as a uint
 uint256 platformFee = (amountPaid * commissionPercentage) / 100;
 amountPaid -= platformFee;
Just knowing the commission percentage and what was paid lets you calculate it within a function, then you can call the.transfer() function twice with the respective values.

The Policy Impact of Ideas

- Seminar Room 4, Chrystal Macmillan Building
How ideas influence policy is a subject of continuing research and debate. In order to explain policy change many have argued that ideational processes help to construct policy problems; shape the assumptions that affect the content of reform; and become, at times, discursive weapons. However there are also powerful institutional enablers and constraints on the policy impact of ideas. In this paper, I propose to examine the role of the three dominant ideas in public health: "health" is special; science is essential; and, social justice is paramount.
The first part of the paper outlines a framework for thinking about ideas and policy change. The next three sections explore in turn how particular conceptions of "health"; "science"; and "social justice" define the public health account of policy making. The final section briefly applies the conceptual argument to two flash points in contemporary public health: the controversy surrounding the INSITE safe injection facility in Vancouver and, more broadly, calls for action on socioeconomic inequality in the name of health. In both cases the goal is to explore the impact of institutional arrangements on the policy impact of the core ideas animating public health.

Java Design Pattern
I'm new to design. I have a small project where java classes use dummy data when not connected to a server. I have a condition in a class that switches between dummy data and server data depending on a flag. Is there a better way to accomplish this?

Instead of manipulating your code with an "if" statement, you should write an interface that defines all the methods needed to communicate with the server, and reference that interface instead of a specific implementation. Then, your "dummy data" implements this interface.
The advantage of this is that your code will be written in a way that is independent of the server implementation. This will allow you to modify data on the server without changing the client implementation.
+4
source
You need a data access object, or an object that acts as a proxy between the requesting program and the data.
You ask the DAO for data and based on its configuration, it responds with your server data or other data. Other data could be new instances of classes, data from text files, etc.
In this image , "Business Object" is your program, "Data Access Object" is a reconfigurable gatekeeper, Transfer Object "is an object representation of the requested data, and" Data Source "is the interface you previously used for data access When the Data Access Object is in place, it's easy to add code to it to "select" the correct data source (DummyDataSource, FileDataSource, JDBCDataSource, etc.).
+1
source
I would recommend using the store pattern to encapsulate your data layer. Create an interface for the repository and create two concrete implementations, one for dummy data and one for server data. Use the Factory pattern to create your repository. Factory will return the correct concrete Repository implementation based on whether you are connected or not.

Proxy_pattern is the best fit for your use.
In short, a proxy is a wrapper or agent object invoked by the client to access the real service object behind the scenes.

The Governance of the International Monetary System
This paper proposes a reformed architecture of the international monetary system based on three pillars. The first is a representative apex organization, which can be understood as a transformation of the G-20 into a representative international institution. The second is the continuous reform of 'voice and participation' of developing countries in the Bretton Woods Institutions and global regulatory bodies. The third is the design of a 'dense', multi-layered architecture, with the active contribution of regional and sub-regional institutions, in a sense copying in this regard the denser architecture in place in the system of multilateral development banks.

Adding decorative wood pieces to a plain mirror is an inexpensive way to add color to a room or continue a decorating theme in a room. Decorative wood pieces can be found in all shapes and patterns at hobby and craft stores that can be finished to match the exact colors of a room. The decorative pieces are especially suited to updating or continuing a decorating theme in a child's room or bathroom. Gluing wood pieces to a mirror is an easy process that takes minimal preparation and supplies.
Things You'll Need
Wipe the mirror with microfiber cloth to remove dirt and dust.
Video of the Day
Dampen a rag with rubbing alcohol and clean the mirror where the wood will be attached. The rubbing alcohol will remove any greasy residue on the mirror that might affect adhesion.
Apply a thin line of adhesive that is good for both glass and wood up and down the back of the wood piece in a zigzag fashion. Do not place the adhesive line right next to the edge of the wood piece, or it may squeeze out onto the mirror.
Press the wood in place on the mirror. Hold the wood piece in place long enough for the glue to set, or you can tape the wood in place while it dries. Refer to the glue manufacturer's instructions for the drying time, but realize that humidity can increase the amount of time it takes glue to dry. An average amount of time for glue to set is usually two to five minutes.
Use a blow dryer to speed up the drying process of the adhesive.

Can't make ring homomorphism from ring of integers to a residue field
Reported by: robharron Owned by:

Component: number fields Keywords: Ring of integers, homset, residue field

Authors: Reviewers:

Branch: Commit:
Dependencies: Stopgaps:
Description
It doesn't seem possible to create a ring homomorphism from an order in a number field to a residue field of the number field. For instance:
sage: K.<a> = NumberField(x^2-2)
sage: OK = K.ring_of_integers()
sage: P = K.primes_above(3)[0]
sage: kappa = P.residue_field()
sage: abar = kappa.gen()
sage: im = [g.polynomial().change_ring(ZZ)(abar) for g in OK.gens()]
sage: iota = OK.hom(im)
raises "TypeError?: images do not define a valid homomorphism".
Now, if instead you pass "check=False" to OK.hom, you of course get an iota, but you are unable to evaluate it:
sage: iota = OK.hom(im, check=False)
sage: iota(K.gen())
This raises "TypeError?: unsupported operand parent(s) for '*': 'Rational Field' and 'Residue field in abar of Fractional ideal (3)'". I tried being clever and doing:
sage: iota(OK(K.gen()))
but got the same error. Tracing it back, when sage tries to evaluate iota at an element a, it calls a._im_gens_(kappa, im) and this is totally wrong for this homset. Rather it is meant for homomorphisms between number fields. Basically, it looks like we need a function _im_gens_ for OrderElement? types. It should take the element a written out in the basis given by OK.gens() and replace the basis elements with the element in im.

History of Scotlandville High SchoolJanuary 3, 2013
By Peggy Carter.
This past school year, the students from a class at Scotlandville Magnet High School were assigned the task of writing the history of their school. They soon discovered that there was very little written information about their school. So Pamela Donaldson, a Library Technician who works with the Black Heritage Room at the East Baton Rouge Parish Scotlandville Branch Library, and Elva Jewel Carter (Peggy), the Reference Librarian at Scotlandville Branch Library, decided to research the subject so that we would have some written history about the school. We decided to create an InfoGuide on a useful topic.
We gathered information from a variety of sources: newspapers, newspaper archives, books, and people. It took a long time to get all the information and check for accuracy since the school began in 1952 and changed many times to fit the needs of the community. Scotlandville Magnet High School started as a junior high school, evolving into a junior/senior school, a senior high school, a magnet high school and finally a three-tier school with educational programs for magnet and community students as well as an engineering curriculum.
The final result of our research can be accessed through this The History of Scotlandville High School InfoGuide.

With last week's cold snap wreaking havoc with water supply and availability in many parishes, St. Charles Parish was one that did not have to issue a boil water advisory like many of its neighbors.
St. Charles Parish Waterworks Director Robbie Brou said the parish has the ability to treat more than twice the average daily water demands of its residents, a useful distinction in these situations. That infrastructure, along with some conservation by parish residents, kept the situation from escalating and requiring a boil mandate.
"We also maintain a one day supply of drinking water in storage at our facilities," Brou said. "These abilities were stretched to their maximum due to the number of customer leaks and people flushing water lines to avoid frozen pipes. This prompted us to ask our customers to restrict or limit water usage to avoid low water pressure in the system and the resulting boil water advisories."
Even so, Brou admits waterworks staff and parish authorities were very concerned throughout the course of the cold weather event.
"Even with the additional capacity we were supplying more water to the distribution system than we could treat," Brou said. "We were able to do this because of the one day's supply of water in storage. However as the level of water in storage continued to drop during the event there was growing concern that we could not maintain the rate of flow from the plants for much longer without facing low water pressure issues."
Brou credited the department's distribution crews that worked diligently to locate and turn off leaking water services for both days of the event, as well as repairing the two water main breaks in the parish's system.
The call to residents to conserve reversed the trend of having to distribute more water than the department was treating, which allowed for the chance to start filling its storage tanks.
The Department of Health requires water systems to maintain water pressure above 15 PSI. All water distribution lines have small leaks in them and the maintained positive pressure on the inside of those pipes ensures those leaks are leaking out and that nothing is leaking in.
"The parish places a large emphasis on our water system as it is a critical service that we provide to residents." — Robbie Brou
Brou said the concern and often the need for a boil advisory comes when the pressure falls too low. That can result in ground water leaking into the water pipes and causing potential contamination.
If the water needs of residents exceed the ability to treat it, it can result in low water pressure throughout a system.
Preparation is key in any emergency situation, and this was no different, Brou notes.
"The parish places a large emphasis on our water system as it is a critical service that we provide to residents," he said. "Well-maintained and properly-sized treatment, storage and distribution infrastructure is critical to sustaining water pressure, flow and quality in an event such as we have just experienced, but also in maintaining these every day of the year."

A tribotester with an integrated load sensor based on a strain gauge is typically used to measure the friction coefficient generated by the contact-related sliding motion of two objects. Since the friction coefficient is obtained by dividing the measured friction force by the applied normal force, the normal and friction forces must be measured for accurate analysis. In this study, a tribotester was used to measure the displacement of a cantilever tip using the fiberoptic sensor in a non-contact method. The friction coefficient measurement using the fiberoptic sensor was proven to be valid by calibrating the tip displacement due to normal/friction forces after designing a basic structural cantilever tip based on experiments and simulation analyses. The results obtained by using the fiberoptic sensor-cantilever tip-based tribotester were compared with those obtained using commercial and/or custom-built tribotesters under the same conditions. By designing various shapes of cantilever tips and using simulation analysis, the calibrations of the normal/friction forces and tip displacement could be verified and the coupling effect was evaluated. The performance and reliability of the fiberoptic sensor-cantilever tip-based tribotester, which can be used to determine the normal/friction forces by non-contact displacement measurements without a strain gauge, were verified.

Take the 2-minute tour ×
Lets say I am using IMAP IDLE to monitor changes in a mail folder.
The IMAP spec says that IDLE connections should only stay alive for 30 minutes max, but it is recommended that a lower number of minutes is selected - say 20 minutes, then cancel the idle and restart.
I am wondering what would happen if the mail contents changed between the idle canceling, and the new idle being created. An email could potentially be missed. Given that RECENT is a bit vague, this could lead to getting a message list before the old idle ends, and a new idle starts.
But this is almost the same as polling every 20 minutes, and defeats some of the benefit of idle.
Alternatively, a new idle session could be started prior to terminating the expiring one.
But in any case, I think this problem has already been solved so here I am asking for recommendations.

As you know, the purpose of IMAP IDLE command (RFC 2177) is to make it possible to have the server transmit status updates to the client in real time. In this context, status updates means untagged IMAP server responses such as EXISTS, RECENT, FETCH or EXPUNGE that are sent when new messages arrive, message status is updated or a message is removed.
However, these IMAP status updates can be returned by any IMAP command, not just the IDLE command - for example, the NOOP command (see RFC 3501 section 6.1.2) can be used to poll for server updates as well (it predates the IDLE command). IDLE only makes it possible to get these updates more efficiently - if you don't use IDLE command, server updates will simply be sent by the server when the client executes another command (or even when no command is in progress in some cases) - see RFC 3501 section 5.2 and 5.3 for details.
This means that if a message is changed between the IDLE canceling and the new IDLE command, the status updates should not be lost, just as they are not lost if you never used IDLE in the first place (and use NOOP every few seconds instead, for example) - they should simply be sent after the new IDLE command is started.

An object that creates and manages the contents of a single-column table interface.
- watchOS 2.0+
You use a table object to set the number and type of rows and to configure the data objects for those rows. Take the following steps to configure a table object and fill it with data:
Define one or more row controller types in your storyboard.
Define a custom data class to manage the contents of each row type.
Tell the table object how many rows (and of what type) to display at runtime.
Use instances of your custom data class to configure each row's contents.
Do not subclass or create instances of this class yourself. Instead, define outlets in your interface controller class and connect them to the corresponding objects in your storyboard file. For example, to refer to a table object in your interface, define a property with the following syntax in your interface controller class:
During the initialization of your interface controller, WatchKit creates a new instance of this class and assigns it to your outlet. At that point, you can use the object in your outlet to make changes to the table.
Defining Your Table's Rows
After adding a table object to your storyboard, configure the row controller that comes with the table. A row controller defines the appearance of a specific type of row. A table comes with one row type initially and you can add more later. Each row controller in your table requires some minimal configuration to be usable at runtime.
Each row controller must have a name, which you set using the Identifier property in the Attributes inspector. You use this name to create rows of that type later.
Each row controller must have an associated class, which you set in the Identity inspector. At runtime, the table creates instances of your row controller classes for each row in the table.
To configure the contents of a row controller, drag elements from the library and drop them onto the row's group. For most rows, you will want to use a group object as the top-level object. You can also nest group objects to create vertical and horizontal arrangements for your interface objects. To that group, add the objects needed to display the row's contents. Figure 1 shows how a configured row appears in Xcode.
Each row controller needs a class to manage the contents of the row at runtime. The class acts as a proxy for the row in your code and stores the outlets you need to configure the contents of the row. Listing 2 shows the definition of a custom
My class that could be used for the row controller in Figure 1.
Setting the Number of Rows at Runtime
To fill a table interface object with data, use the
set method. These methods specify the type (and number) of rows to add to the table. If all rows are of the same type, use the
set method. If you use more than one row controller in your table, use the
set method. The row type string corresponds to the name you entered into the Identifier property for that row controller in your storyboard.
When you add rows to a table, WatchKit creates the rows in your Watch app and instantiates the classes corresponding to those rows in your WatchKit extension. The newly instantiated classes are stored internally by the table object and made available to you through the
row method. Use that method to retrieve each row controller object and configure the contents of the row.
Listing 3 shows an example of how to configure a table object from your interface controller. The
todo property referenced by the method is a custom property that contains the
WKInterface object being configured. After getting the data for the rows, the method calls the
set method to create the rows. It then iterates over the newly created row controller objects, configuring each one's label with the text for the to-do item.
When you want to update the contents of a table, call
set again with the new row type information. Calling these methods again forces the table to discard the old rows and create new ones. To insert new rows without removing the old ones, use the
Responding to Taps in Table Rows
In your storyboard, create a segue between a row controller and a destination interface controller. When the user taps on a row of that type, the system automatically pushes the destination interface controller onto the screen. To pass data to the destination controller, override your current interface controller's
context method, and return context data based on the selected row.
Alternatively, you can explicitly respond to taps in a table row by implementing your interface controller's
table(_: method. Use that method to present a different interface controller or to perform any other relevant tasks.
Supporting Item Pagination
Item Pagination lets users easily navigate through lists of items. When the user selects an item from the table, the app displays a detailed view for the item. The user can then scroll up and down to navigate between other sibling items from that table. For example if the user selects a stock symbol in the Stocks app, it will load the details for that stock. They can then scroll vertically to navigate to other stocks.
Item Pagination is disabled by default. To enable it, perform the following steps:
In the storyboard, enable the table's Item Pagination option in the Attributes inspector.
In the storyboard, define segues for all of the table's row controllers. Your table must use segues to drive its navigation.
If you programmatically navigate through a table's items (for example, when launching from a complication to a specific interface controller), be sure to use the table's
performmethod, instead of the interface controller's
Controller(with Name: context:)
performmethod lets watchOS know which table and which row initiated the segue. The system needs this information to provide the correct sibling items as the user scrolls.
Interface Builder Configuration Options
Xcode lets you configure information about your table interface object in your storyboard file. Table 1 lists the attributes you can configure in your storyboard and their meaning.
The number of row controllers supported by the table. Change the value to add or remove new row controller objects to the storyboard file.
The amount of spacing (in points) between rows.
The background image to display behind the table's items. Do not set an image if you want the background color or image of the underlying interface controller to be visible.
The background color for the table. Set the color to clear if you want the background color or image of the underlying interface controller to be visible.
A checkbox that determines whether Item Pagination is enabled. For more information on Item Pagination, see Supporting Item Pagination.
For each row controller in your table, Table 2 lists the attributes you can configure and their meaning.
A checkbox indicating whether rows of this type are enabled and tappable. When this option is disabled, tapping the row does not highlight the row or report the action to the table.


Saving layouts
You can save your Monitoring task layouts in an areas view that everyone can access.
What you should know
When you save a Monitoring task as a layout, the tile pattern, and the entities displayed in each tile (tile content) are saved. The monitoring state (event and alarm monitoring) of the tiles, and the video mode of the cameras (live or playback) are not saved with the layout.
NOTE: The Save as layout menu item is only available in a Monitoring task.
The benefits of saving a Monitoring task layout are as follows:
 - You can quickly change the monitored entities (cameras, doors, and so on) without leaving the Monitoring task.
 - You can share layouts with other users who have access to the area view where the layout was saved.
To save a Monitoring task as a layout:
 1. In the Monitoring task, right-click the task tab and click Save as layout.
 NOTE: Only users with the required access rights to the area can view or modify this layout.
 2. In the Save as layout dialog box, use the drop-down menu to select the area where you want to save the layout.
 3. Enter a Name for the layout.
 Example: If you are currently monitoring your parking lot cameras, you can save your Monitoring task as a layout with the name Parking lot - Monitoring layout.
 4. (Optional) Enter a Logical ID.
 5. Click Save.

Chair for Religious History of Canada - Home
The Research Chair for Religious History of Canada was created by the Council of Administration of Saint Paul University in April 2013. Like the Centre of the same name, which it is replacing, the Chair aims to promote quality research in the field of Canadian religious history by providing researchers working in this area with research instruments that may be useful for them and by organizing gatherings that allow them to share the results of their research or to open up new fields of research. The first projects include putting online documents of Canadian significance from the archives and libraries of Rome, undertaken between 1977 and 2009 by the Research Centre for Religious History of Canada, and the establishing of a major research project on the history of Oblate missions with First Nations peoples. The first holder of the Chair is Professor Pierre Hurtubise, o.m.i., m.s.r.c., who was until recently the director of the Research Centre for Religious History of Canada.

Summer rainfall in Tonga is expected to be severely diminished with only half the expected monthly rainfall in some places, Tonga's Meteorological director warned today, after assessing the latest El Niño forecasts.
The current situation is that Niuafo'ou recorded the highest maximum day time temperature of 30.0°C on 1 August and the lowest night time minimum temperature was 12.0°C on 17 August in Fua'amotu, Tongatapu.
Rainfall received across the country during August was normal over the Niuas and wetter than normal throughout Tonga.
Rainfall in the last three months of June-August was below normal in the Niuas and Vava'u, normal in Ha'apai and Fua'amotu and above normal in Nuku'alofa.
Meanwhile, from August 8-12 rainfall eased the dry conditions experienced as more than 100mm rainfall received in 24-hours in Tongatapu, Ha'apai and Vava'u.
However, rainfall foreast for the next three to six months continues to favour drier than normal conditions for Tonga. Communities are advised to collect as much water as possible because this pattern of three month outlook is typical El Niño years.
The islands with rainfall deficiencies are likely to intensify in the current dry season from May-October, while below normal rainfall are favoured into the wet season, November-April.
The Meteorological Office will be issuing El Niño updates every two-weeks from now to get the message across, said 'Ofa.
For Tonga, El Nino usually brings cooler night time temperatures from May to October, less rainfall and more cyclones than usual.
El Nino years are excellent for growing sweet potatoes (provided enough water is given) and crops that depend on cooler night time temperatures but it not good for rain dependent crops in the summer time.
Fruit trees and vanilla also tend to do well during El Nino due to stress induce flowering while tuna fisheries on the other hand tends to be poor due to tuna stocks migrating away from Tonga waters.


error: attribute 'a' at (string):1:12 already defined at (string):1:5
nix-repl> let a = 3; in let a = 8; in a
8

You cannot refer to variables in a let expression outside of it:

nix-repl> let a = (let b = 3; in b); in b
error: undefined variable 'b' at (string):1:31

You can refer to variables in the let expression when assigning variables like with recursive sets:

nix-repl> let a = 4; b = a + 5; in b
9

So beware when you want to refer to a variable from the outer scope, but it's being defined in the current let expression. Same applies to recursive sets.

With expression

This kind of expression is something you hardly see in other languages. Think of it like a more granular "using" of C++, or "from module import *" from Python. You decide per-expression when to include symbols into the scope.

nix-repl> longName = { a = 3; b = 4; }
nix-repl> longName.a + longName.b
7
nix-repl> with longName; a + b
7

That's it, it takes a set and includes symbols in the scope of the inner expression. Of course, only valid identifiers from the set keys will be included.

If a symbol exists in the outer scope and also in the "with" scope, it will not be shadowed. You can however still refer to the set:

nix-repl> let a = 10; in with longName; a + b
14
nix-repl> let a = 10; in with longName; longName.a + b
7

Laziness

Nix evaluates expression only <a href="_URL_ needed. This is a great feature when working with packages.

nix-repl> let a = builtins.div 4 0; b = 6; in b
6

Since "a" is not needed, there's no error about division by zero, because the expression is not in need to be evaluated.

That's why we can have all the packages <a href="_URL_ here, yet access to specific packages very fast.

Next pill

...we will talk about functions and imports. In this pill I've tried to avoid function calls as much as possible, otherwise the post would have been too long.

Nix pill 5 is available for <a href="_URL_ here.

In the previous <a href="_URL_ pill we have installed Nix on our running system. Now we can finally play with it a little, things also apply to NixOS users.

Enter the environment

In the previous pill we created a nix user, so let's start by switching user with su - nix. If your ~/.profile got evaluated, then you should now be able to run commands like nix-env and nix-store.
If that's not the case:

$ source ~/.nix-profile/etc/profile.d/nix.sh

I remind you, ~/.nix-profile/etc points to the nix-1.7 derivation. At this point, we are in our nix user profile.

Install something

Finally something practical! Installation in the nix environment is an interesting process. Let's install <a href="_URL_ a simple command line tool for playing with the Nix language. Yes, Nix is a <a href="_URL_ lazy, functional language, not only a set of tools to manage derivations.

Back to the installation:

$ nix-env -i nix-repl

installing 'nix-repl-1.7-1734e8a'
these paths will be fetched (18.61 MiB download, 69.53 MiB unpacked):
[...]
building path(s) '/nix/store/f01lfzbw7n0yzhsjd33xfj77li9raljv-user-environment'
created 24 symlinks in user environment

Now you can run nix-repl. Things to notice:

We did install software as user, only for the nix user.

It created a new user environment. That's a new generation of our nix user profile.

The <a href="_URL_ manages environments, profiles and their generations.

Pretty much what the title says. My base question is this. Assuming I take a piece of steel, and a piece of PVC plastic and I measure both their temperatures and find they are the same. I then take a look at the vibration speeds of the individual molecules would they be the same as well?
Here's a rough example:
I measure both the steel and PVC and find them both at 100F, and then I measure the vibrations of a molecule in the steel and find it to be moving at 10 miles an hour. Would the PVC molecules also be moving at 10 miles an hour?
I'm sure I'm not using the correct units of measure to measure the vibration, but I didn't know what the correct unit of measure is for something like that. Hopefully it gets the point across.

No, because the atoms in steel and plastic have different masses.
Your example is a bit more complicated than it need be because steel (well iron) is an element while plastic is a compound. This complicates things because molecules can have internal motions that contribute to the energy. A better comparision might be between lead and lithium. These are both elements to you just need to consider the motions of the Pb and Li atoms. For a given kinetic energy a lead atom will be moving more slowly than a lithium atom because it's heavier.
You could think of it this way: if you touch the piece of lead to the piece of lithium the atoms will be in contact so they'll swap energy by bashing into each other. If a lead atom hits a lithium atom the Li atom will recoil a lot faster than a Pb atom.

Its probably simpler to think of gases. From the Wikipedia article on the Kinetic Theory of Gases, the average kinetic energy of molecules in an ideal gas is 3/2 k_b T. But since molecules of nitrogen (28) are lighter than molecules of oxygen (32), it follows that at the same temperature, an "average" nitrogen molecule is moving about 7% faster than an "average" oxygen molecule. – Anonymous Jun 2 '12 at 17:05

This study evaluates the price setting behavior across main cities of Pakistan by employing the micro data from retail price survey. The most contemporary research technique of Duration Analysis is employed where survivor functions are estimated by most illustrious nonparametric Kaplan-Meier and Nelson-Aalen Estimators. Hazard Functions for various product groups are also estimated by employing parametric Weibull Hazard Model. Results confirm that perishable food items have shortest duration of one week for most of the spells, where government regulation caused prices to change more frequently. It is found that on average small cities faced lower hazard and thus comparably lesser price change, whereas, months of March, April and October witnessed relatively high hazard rates. The study classifies nine commodity groups into two categories. First is high frequency group and second is increasing hazard group. These classifications are believed to assist policy makers in assessing inflation dynamics in Pakistan. The study significantly contributes to the existing literature, firstly, by applying more scrupulous nonparametric and parametric techniques of Survival analysis. To the best of our knowledge, this technique is not yet applied in Pakistan for examining the price behavior. Secondly, as the price setting mechanism in Pakistan is not studied before by employing the high frequency micro price data, therefore, panel data estimation contribute significantly to the existing literature.
