Top 3 Clients by Order Value
Compute the top 3 clients by order value according to the detailed order data. The basic train of thought is to group the orders by clients firstly, secondly sum up the total value of orders placed by each client, thirdly sort the order by the summary value, and lastly filter out the top 3 groups according to the serial numbers. In this case, the summary value sorting and filtering by the serial number is the difficult point. However, with the overall sheet design module and sorted computational module of esCalc, this point can be solved easily.
1. Get the data from the order sheet through the wizard
2. Group by client. Right-click on any cell outside the header of column B, select Quick operation->group, as shown in the below figure:
The grouping result is shown below:
3. Calculate the summary value of each client. In any cell of the summary zone, enter the summation formula, for example, enter {D3}.sum() in D2, which indicates the sum of all homo-cells of D3. Formulas will be copied and pasted to the homocells of D2 (i.e. D7, D10, and other cells) automatically, as shown in the below figure:
4. Sort by the summary value. Right-click on the cell where the summary value is located (any cell of D2, D7 or D10). Right click and select Quick operation->Desc, as shown in the below figure:
The sorting result is shown below:
5. Filter by the serial number. In the Summarizing Area (for example the cell B2), right click and select Operation->Filter, as shown in below figure:
In the dialogue, input the formula "#<=3", and # represents the serial number in this case. Because it is summary zone, the # represents "serial number of each member in the group", as shown in the below figure:
The filtered result of the computational goal, as shown in the below figure:
6. To make it more convenient for viewing, you can also click the grouping level 1 on the top left corner, as shown in the below figure:

Taiwan Film Screenings (Understanding Taiwan Through Film and Documentaries)台灣光點‧電影放送
Dr Dafydd Fell and Dr Ming-yeh Rawnsley discuss the Taiwan Film Screenings at SOAS
Over the past 30 years Taiwan film has had an outstanding record of achievement at major film festivals, particularly those in Europe. To factor in this enormous triumph SOAS has offered a course on Taiwan film since 2005 – a course that has been tremendously popular with students. The value of Taiwan's films and documentaries goes beyond their artistic quality, for they also offer a key platform for understanding modern Taiwan. This has been the prime motivation behind this new project. Its goal: to facilitate regular screenings of Taiwanese films and documentaries. Each screening will feature a follow-up Q&A session with invited film makers, actors, or film scholars and critics.
The films will be chosen to integrate closely with existing Taiwan courses at SOAS and the regular Taiwan Studies Seminars. The films shown will reflect key themes, such as important trends in Taiwan's history, social, economic and political change, cross-Strait and international relations, and cultural development. We already supplement our teaching with reference to clips from Taiwanese films and documentaries, but regular screenings of films and the opportunity to question and directly interact with film makers and specialists will greatly enhance students' understanding of contemporary Taiwan. We also intend that these screenings will be organised in close cooperation with the Taiwan Academy in London, which will be inaugurated in the near future. Overall, it is hoped that the screenings will help raise wider awareness and understanding about modern Taiwan and its vibrant creative industries.
The project will host nine film screenings during each academic year. These will include a mix of feature films, short films, and documentaries. There will be three film showings each in term 1 (September-December) and in term 2 (January to March); in term 3 we will devote an entire day to three screenings as part of our annual Taiwan Studies Summer School. The film screenings shall be open to the general public and advertised widely on our Taiwan Studies website and through our extensive emailing lists.
The Understanding Taiwan through Film and Documentary Screening Series is supported by the Ministry of Culture's Spotlight Taiwan Programme. Special Thanks to Dr. Samuel Yin for his generous support to the Spotlight Taiwan Programme.

I would like to count number of layers in a stack with value equal to raster pixel value. Here is my current try:
r1 <- calc(s, fun=function(x){sum(x == r)})
I get two errors
Error in FUN(newX[, i], ...) : unused argument (na.rm = TRUE)
and
Error: cannot allocate vector of size 1.9 Mb
Where I'm going wrong?

Yeah ok, raster::calc() only operates on a single object, so your formula is essentially trying to total up all the occasions where one of your stack's cells equals a whole raster, which is never.
Try this: first, stack r and s. This means each pixel in the output stack becomes a vector where element 1 is the reference value and the rest are comparison values. Then run calc on that object, with a function like
function(x) {
 comp <- x[1]
 main <- x[2:length(x)]
 length(main[main == comp])
}
This should return a raster where each cell is a count of how many stack layers equal the overlying reference cell value.

Abstract
In knot theory several knot invariants have been found over the last decades. This paper concerns itself with invariants of several of those invariants, namely the Homology of racks, quandles, biracks and biquandles. The software described in this paper calculates the rack, quandle and degenerate homology groups of racks and biracks. It works for any rack/quandle with finite elements where there are homology coefficients in Zk. The up and down actions can be given either as a function of the elements of Zk or provided as a matrix. When calculating a rack, the down action should coincide with the identity map. We have provided actions for both the general dihedral quandle and the group quandle over S3. We also provide a second function to test if a set with a given action (or with both actions) gives rise to a quandle or biquandle. The program is provided as an R package and can be found at _URL_

(1) Overview
Introduction
This introduction is divided into two parts: First, we are going to give some mathematical background before introducing the software itself.
Mathematical Background
Racks and Quandles were first described by John Conway and Gavin Wraith in 1959 in unpublished correspondence. In [2], David Joyce showed that racks are indeed a knot invariant. Subsequently, Fenn and Rourke introduced racks as proper knot invariants in [3]. It is instructive to consider racks as groups without their multiplicative elements. Formally, a rack is defined as a set of elements endowed with a binary operation which satisfies the following axioms (where the third axiom holds only for a quandle, not for a rack) for all a, b, c in the rack/quandle R:
 1. a, bR∃! cRs.t.ac = b
 2. ba(c)(bc)(c)=ac
 3. aa = a (only quandle)
Biracks and Biquandles are defined similarly, now with two operations, satisfying the following axioms:
 1. abcb = acbc
 2. abcb = acbc
 3. abcb = acbc
 4. aa = aa (only biquandle)
In addition, both operations satisfy the rack axiom 1.
Here, the up and down actions allow us to introduce a switch map via fa(x) = xa, fa(x) = xa as S(a, fa(b)) = S(b, fb(a)). The utility of this is clear when one observes that the axioms can be reformulated using the switch map:
 - S, fa and fa are all bijective.
 - Yang Baxter Equation: S1S2S1 = S2S1S2, where S1(a, b, c) = (S(a, b), c) and S2(a, b, c) = (a, S(b, c)).
This reformulation is more amenable to computational work.
The homology of the biquandle is defined as follows:
Let X be a birack. Then CnR(X) be the free abelian group generated by n-tuples (x1x2xn), xiX, that is, CnR(X)=ZXn.
We define a boundary homomorphism by:
(x1x2xn)=i=2n(1)i[(x1xi^xn) x1xi xi1xi(xi+1)xi(xn)xi]
and (CnR(X), ) is called a chain complex of X.
Furthermore, we have a subchain complex CnD(X) CnR(X), generated by degenerate n-tuples (x1x2xn), xiX with xi = xi+1 for some i. Together with the boundary homomorphism, (CnD(X), ) is is called the degenerate chain complex of X.
Using both of those chain complexes, we can define the biquandle chain complex via the quotient chain complex, CnQ(X)=CnR(X)/CnD(X). This gives the following short exact sequence of chain complexes:
0CnD(X)CnR(X)CnQ(X)0.
We can then define the birack, biquandle and degenerate homology groups in the usual way. In addition, we have the following long exact sequence of homology groups:
HnD(X)HnR(X)HnQ(X)Hn1D(X)
The algorithm for the homology calculation is described in [1] for this specific software.
Software
The software, which is provided as an R package, can be accessed on github. It provides two primary functions. One of these calculates the homology of racks and biracks, whilst the other verifies if a rack or birack is induced by a given set with one or two actions.
Implementation and architecture
This software is implemented in R. It has been tested on MacOS X, CentOS/Ubuntu and Windows without any problems.
The algorithm for the homology calculation is described in the paper [1].
The program is divided into the following two main parts: The calculation of the boundary matrix and the subsequent calculation of the Homology. For a graphical description see the following Figure 1, which was created with the following code:
 - library(proftools)
 - Rprof(tmp <- tempfile(), line.profiling = T); homology(4,5,F);Rprof(append=F); pd <- readProfileData(tmp)
 - plotProfileCallGraph(pd,style=google.style,score="total",nodeSizeScore = "none",layout="dot",rankDir = "LR")
Figure 1
Call graph for the calculation of the H4R(Z5).
The boundary matrices are computed using the functions boundary_matrix (for quandle and rack boundary matrices) and boundary_matrix_degenerate (for degenerate boundary matrices), respectively. The methodology of both functions is similar, differing only in the manner in which degenerate or non-degenerate entries are removed where required. In particular, after creating a right-sized matrix, they call boundary_names or boundary-names_degenerate to create the row and column names of the boundary matrix. After this, they loop through the column names to calculate their boundaries and construct the matrix (for details see [1]). These boundary matrices represent the boundary maps of the simplicial complex of the rack/birack.
After both boundary matrices have been calculated, they are returned to the homology and degenerate_homology functions, respectively. As is the case for the boundary matrices functions, these two functions only differ in the boundary functions called and in their respective output texts.
As an aside, those two functions should be the only ones that would have to be called by the user in order to calculate a homology.
Following on with the algorithm described in [1], those two functions calculate the image and kernel of the boundary map representations (the boundary matrices) before finding a representation of the homology group. For this, they call various functions, namely findX, which "finds X" (this is defined in [1]), row_space, which calculates a basis of the row space of a matrix, matrix_rank, which calculates the rank of a matrix and GaussianElimination, a function written by Prof John Fox (see [4] for a source) which does a Gaussian Elimination on a matrix and returns its reduced row echelon form.
Using the function smith, the smith natural form is obtained from the representation matrix of the homology. This is done via repeated calculation of the hermite normal form of the matrix and its transpose, using the hermiteNF function from the numbers package, [8]. In addition, this function checks if the diagonal of the matrix is in the correct form via the function check_more_push and, if required, will call push_down to do what the name implies.
Finally. The homology group is obtained using the diagonal of the smith normal form.
The second function of this package, the testing if a give operation or operations give rise to a quandle or biquandle is done via the function S_test. This function receives as input the order of the underlying set and then proceeds to test the two requirements for a quandle/biqua


Fixing a (minor) PowerCLI 6 R1 issue
With PowerCLI 6 R1 a major change was introduced, PowerCLI now has modules !
Such a major change is bound to introduce some minor nuisances, as some PowerCLI users have already discovered. This post will try to tackle some of these nuisances.
pcli-v6-bandaidThe first issue is with the PSConsoleFile, called vim.psc1, which was often used in batch invocations of PowerCLI scripts. Unfortunately this is a breaking change, but it can easily be fixed as this post will show.
The second annoyance has to do with the PowerShell environment variable called $env:PSModulePath. The installation package for PowerCLI 6 R1, sets the module path in the user environment variable, which might cause an issue. Read on.
PSConsoleFile
The PSConsoleFile is used to load PSSnapins and can be passed on the powershell.exe command via the PSConsoleFile parameter.
This was used quite often to run PowerCLI scripts as batch jobs or as scheduled tasks. See for example Alan Renouf's excellent post called Running a PowerCLI Scheduled task.
In PowerCLI 6 R1, the PSConsoleFile is used by the PowerCLI initialisation script (Initialize-PowerCLIEnvironment.ps1) to load the PSSnapins and the Modules. But to enable that for that script, the vim.psc1 now contains a PSModules tag, which is afaik, not a supported tag in a PSConsoleFile.
As a result, when you try to start PowerShell with the PowerCLI 6 R1 PSConsoleFile, you will see
pcli-v6-batch-psconsole
PSModulePath
During the installation of PowerCLI 6 R1, the module folder is added to the environment variable called PSModulePath. This will allow for example module autoloading.
Unfortunately the PowerCLI 6 R1 installation program adds the module path to the "user" environment variable and not the machine environment variable.
pcli-v6-modulepath
This is not really a problem when you run your PowerCLI scripts with the same account as the one that you used to install PowerCLI. But for scheduled tasks enterprise environments tend to use a dedicated account, so the problem will pop up in that case.
The Fix
Luckily these annoyances can easily be fixed. In fact you use the following script to automate the fixes.
The script is quite straightforward:
 - Check if we are dealing with PowerCLI 6 R1
 - Correct the PSModulePath
 - Correct the vim.psc1 file
Once the script has done its work, you should now be able to run your batch and scheduled tasks with PowerCLI 6 R1 without any changes.
You can validate that the fix works by running a simple test PowerShell task.

Enjoy !

 I suspect the issue is because the PowerCLI do not work with autoload.
 You have to load them explicitly, and the PSSnapin as well. That was one of the reasons I wrote my Enable-PowerCLI function.
 Can you try with the function, just call it in the beginning of your script.
 Dingus McGee
 Can you please post an example of what the vim.psc1 should look like after this script runs? I've not been able to have success using the script, but want to manually modify the vim.psc1 to be able to run batch files via scheduled tasks using PowerCLI 6.0 R3. Thanks
 LucD
 Hi, the fix is only valid for PowerCLI 6.0 R1.
 If you have 6.0 R3, the problem is not there anymore.
 Jonas Jakobsen
 Hi Luc
 I just upgraded from 5.8 R1 to first 6.0 R2 and then 6.0 R3 but this problem is haunting me 🙁
 It seems like PSModulePath is correct both for my batch user and for machine. Running Get-Module -ListAvailable shows the modules but autoloading is not working. Running a powershell.exe with the vim.psc1 does not fix this – "Connect-VIServer cmdlet not found".
 One thing I noted is that running Get-Module -ListAvailable shows no exported commands for the VMware modules but for all other and if I read Microsoft Technet[1] correct this needs to be the case for autoloading to work otherwise get-command won't show them and this is necessary for autoloading to work.
 Any ideas on what to look for?

Do This Exercise to Improve Your Photography Lighting Skills
Practice makes perfect. Consider football players practicing before a game. While practicing, they do all kinds of things that they wouldn't do during an actual game. In practice sessions, they push themselves and their skills to their limits, because they want to improve their skills, agility, strength, and decision making. As a photographer, you should do the same. In the following video, photographer Mark Wallace from Adorama takes you through an exercise to help you stay on top of your photography game:
To understand how to have better control over lighting as a photographer, Wallace takes you through an exercise similar to what classic painters used: a still life. By shooting still life, you will have a better understanding of how to control specular highlights, shadows, and the direction of light. So follow along and start practicing.
Setup for Still Life Photography Practice
For the practice session, Wallace has the following setup:
 - Leica M10 camera with a 50mm lens, set at f/8 for greater depth of field
 - At the other end of the camera, he has some tomatoes, apples, grapes, and a glass pitcher with potpourri. Note that the fruits, vegetables and the glass pitcher are shiny and have specular highlights.
 - The setup is lit with big windows on the side, and one incandescent light on the top.
Exercise to Control Specular Highlights
Since the items that Wallace has chosen are very shiny, they show off reflections of the light source (specular highlights). The first exercise is to control those specular highlights, as they can be very distracting and difficult to deal with even in post. Here's what Wallace does to control the specular highlights:
 - First off, he starts by taking a photo of the fruit and vegetable setup just using the ambient light. This gives him an idea of how the specular highlights appear in the image.
lighting practice with ambient light
 - Taking inspiration from the classic master painters, he approaches the situation with the idea of getting rid of ambient light by closing the windows.
 - He uses a Profoto B2 with a soft box to light the subject. To avoid specular highlights, he places the light setup close to and behind the subject, also making sure that some amount of light is spilled in front of the subject.
 - He then meters the light by pointing the light meters toward the light (and not the camera) and takes the photo as per the reading to get the following result:
lighting practice using still life
Notice the reflection of chairs on the edges of the glass.
The image looks a lot better. However, there are still specular highlights on the glass due to the reflection of the chairs. By getting rid of the chairs, the result is further improved. Notice how being aware of your surroundings can help you in figuring out issues with your photos.
still life lighting exercise
If you look closely, you can still see the light stand behind the subject. Wallace uses a black cloth to cover it up while using a 12 second timer to delay the shutter release.

Using a black cloth to get rid of the light stand
lighting practice activity
The light stand is not visible anymore.
Retouching Still Life Images
Once satisfied with the image, Wallace opens it up in Adobe Lightroom and makes use of adjustment brushes to make local corrections. Here is what he does in post:
 - Add some front light to the underexposed areas (tomatoes, grapes, and apples).
 - Make the background more seamless by reducing the exposure on the edge of the cloth.
 - Get rid of the table legs by reducing the exposure.
 - Add some clarity.
 - Experiment with vibrance.
Once happy with the adjustments in Lightroom, he opens up the image in Adobe Photoshop. In Photoshop, using the Analog Efex plug-in, he experiments with various presets until he's happy.
how to practice photography lighting
While retouching, don't over stress yourself. Feel free to experiment and play around until you're happy with the end result. Remember that you're practicing and learning skills that you will use next time you're on an actual photo shoot.

Artificial open channel structures are expensive infrastructures in terms of their materials, construction and maintenance. Design of a minimum cost channel section involves minimization of the sum of costs per unit length of the channel, subject to uniform flow condition in the channel. In this research, the objective function was expressed using the cost per unit length of the channel for lining, the depth-dependent unit volume earthwork cost, and the cost of water lost due to seepage and evaporation. A general resistance equation was used as an equality constraint. Optimal design of trapezoidal channel sections using genetic algorithm with depth, bottom width and side slope variables was accomplished. Two methods and several Models were evaluated including no restriction and restriction on normal depth, velocity of flow, side slope and top width. Restricted depth, velocity and side slope resulted in higher costs. However restricted top width resulted in lower costs comparing with other models. Also, another model was employeed which used the Manning equation as an equality constraint.

Correlation of Upper-Atmospheric 7Be with Solar Energetic Particle Events
NAVAL RESEARCH LAB WASHINGTON DC E O HULBURT CENTER FOR SPACE RESEARCH
Pagination or Media Count:
A surprisingly large concentration of radioactive 7Be was observed in the upper atmosphere at altitudes above 320 km on the LDEF satellite that was recovered in January 1990. We report on follow-up experiments on Russian spacecraft at altitudes of 167 to 370 km during the period of 1996 to 1999, specifically designed to measure 7Be concentrations in low earth orbit. Our data show a significant correlation between the 7Be concentration and the solar energetic proton fluence at Earth, but not with the overall solar activity. During periods of low solar proton fluence, the concentration is correlated with the galactic cosmic ray fluence. This indicates that spallation of atmospheric N by both solar energetic particles and cosmic rays is the primary source of 7Be in the ionosphere.

How to Install libmsoffice-word-html-writer-perl in Ubuntu 18.04
Install libmsoffice-word-html-writer-perl by entering the following commands in the terminal:
sudo apt update
sudo apt install libmsoffice-word-html-writer-perl
Description:
module for writing MsWord documents in HTML format
MsOffice::Word::HTML-Writer is one way to programatically generate documents targeted for Microsoft Word (MsWord). . MsWord can read documents encoded in native binary format, in Rich Text Format (RTF), in WordML (an XML dialect), or -- maybe this is less known -- in HTML, with some special markup for pagination and other MsWord-specific features. Such HTML documents are often in several parts, because attachments like images or headers/footers need to be in separate files; however, since it is more convenient to carry all data in a single file, MsWord also supports the "MHTML" format (or "MHT" for short), i.e. an encapsulation of a whole HTML tree into a single file encoded in MIME multipart format. This format can be generated interactively from MsWord by calling the "SaveAs" menu and choosing the .mht extension. . MsOffice::Word::HTML::Writer helps you to programatically generate MsWord documents in MHT format. The advantage of this technique is that one can rely on standard HTML mechanisms for layout control, such as styles, tables, divs, etc -- of course this markup can be produced using your favorite HTML module. The added value of MsOffice::Word::HTML::Writer is to help building the MIME multipart file, and provide some abstractions for representing MsWord-specific features (headers, footers, fields, etc.). This is probably the most convenient way for programmatic document generation.

The possibility of creating a high-power X-ray source based on the recombination radiation mechanism has been studied and analyzed. The recombination X-ray radiation from neon, aluminum, and argon was obtained in experiments with plasma liners performed on the GIT-12 setup using a current pulse amplitude of ∼2.5 MA and a leading pulse front width of ∼300 ns. The obtained results show that the recombination mechanism of X-ray generation offers good prospects for the development of a high-power X-ray source with photon energies in the 7-20-keV range.

VizIcon Parallel Coordinates.svg
Parallel coordinates are a way to plot multivariate data. They are primarily used to visualize the relationships between many numeric variables.
Parallel coordinates are a way to plot multivariate data. They are primarily used to visualize the relationships between many numeric variables. The chart gives each variable its own axis and positions it in parallel to the other axes, with the data points plotted as a series of lines along each axis.
Data format
The variable order of the parallel coordinates chart will determine how the axes are arranged. This is important to note because it is much easier to detect patterns between variables that are positioned adjacent to each other.
In Displayr, the axes are ordered exactly as the variables are ordered in the variables list. Re-ordering the axes in a meaningful way will make it easier to discover patterns and correlations.
Parallel coords variable order.png
Parallel coords viz.png
Interpretation
A parallel coordinates chart can appear messy and cluttered. Here are some things to look for when interpreting the results.
Patterns between colored lines Setting the color variable (Inputs > DATA SOURCE > Color variable) will color-code each line according to the assigned variable. This allows you to more easily detect patterns and correlations.
Clusters on a single axis Data points may be clustered around certain areas of an axis, which may be particularly noteworthy if the clusters are also differentiated by color on the chart.
Patterns between axes Correlations between axes adjacent to each other indicate that the variables are in some way connected.
Example
The following example uses data the Iris flower data set, which measures certain characteristics of three species of Iris.
Create a Parallel Coordinates Chart in Displayr
1. Go to Insert > Visualization > Parallel Coordinates
2. Under Inputs > DATA SOURCE > Variables, Select the variables you want to include
3. Under Inputs > DATA SOURCE > Color variable, select the variable you want to color code.
Tip: In step 3, select the variables in the order you wish to arrange the axes to prevent having to reorder it later.
Object Inspector Options
The following is an explanation of the options available in the Object Inspector for this specific visualization. Refer to Visualization Options for general chart formatting options.
Chart
APPEARANCE
Variables Variables to show in the chart. These must come from the same data set. Each variable will be shown on a separate axis.
Color variable Optional variable used to color the lines in the chart. It must be a variable from the same data set as ::Variables, and can even be one of the variables included in Variables. If no variable is supplied, then all the lines in the chart will shown in the same color.
Variable names Use variable names instead of variable labels to label axes of chart.
Tidy labels Extract common prefixes from axes labels.
Reverse axes Show smallest values at the top of the y-axes.
Enable interactions When interactions are enabled users can click and drag on chart to select lines. However for large data sets it may be more efficient to turn off interactions.
Render lines progressively Lines are gradually added to the chart, so the user can see when multiple overlapping lines are added.
Line opacity Set transparency of lines to a numeric value between 0 (clear) to 1 (opaque). Note that overlapping lines of multiple colors will always be shown as a dark line (black hue).
Line colors Select a color palette to use if Color variable is provided, or a single color if not.
Rotate variable label Show variable labels at perpendicularly. This is useful for displaying longer labels. You may also need to adjust margin dimensions.

Authentic Assessment - " Mission Possible or Mission Impossible?
Faculty of Computing, Health and Science
School of Natural Sciences / Centre for Ecosystem Management
This paper describes the successful implementation of authentic assessment items within two undergraduate units in the School of Natural Sciences. It argues that the content of any authentic assessment needs to ne contextualized and thus discipline specific. Within the field of environmental planning, there is an ongoing debate about both the nature and definition of the subject which makes creation truly authentic assessment problematic. The environment planning unit now includes three assessment items which replicate many of he practices required of an environmental planner. In contrast, in the field of chemistry, it is difficult to replicate the work practices of a professional chemist within the University learning environment. In the chemistry unit, an industry trip and seminar have been included to provide a more authentic learning environment for the students. The paper shows that it is possible to create assessments that are authentic and also meet the University's learning requirements.

noun: no-claims bonus; plural noun: no-claims bonuses; noun: no-claims discount; plural noun: no-claims discounts
- a reduction in the premium charged for insurance when no claim has been made during an agreed preceding period.
What is a no claims bonus?
A no-claims bonus (NCB), or no claims discount, is a count of the number of years in which you haven't made a claim on your car insurance policy.
Its worth varies from insurer to insurer, but an NCB of five years or more, for example, could give you a 60-75% discount on your premium.
How do I build my NCB?
For every year you're insured without making a claim, you'll earn another year's NCB. Some companies offer accelerated policies where you can earn a bonus in 10 months rather than 12.
You can build up an unlimited number of NCB, but most insurers will only use a maximum of five years when working out a discount.
If I make a claim, how is my NCB affected?
If you make a claim on your policy where your insurer pays out, you'll generally lose some, or all, of your no-claims bonus.
But if you're hit by another car and it's agreed that you weren't at fault, your insurer may be able to reclaim the payout from the other car's insurer and your NCB may not be affected.
In cases where fault can't be agreed on, insurers may split the cost of the claims and both drivers' NCB could be affected. This includes if your car is stolen or damaged by bad weather.
If you pay for a new policy with a reduced NCB and are later found not at fault, you can usually get your NCB reinstated and a refund on the extra premium you paid.
Should I protect my NCB?
Protecting your NCB allows you to have a certain amount of "at fault" accidents without affecting the bonus. So if you have an accident, the NCB remains intact even if your insurer can't claim their costs back. Each insurance company have different rules regarding how many claims are allowed.
This won't necessarily stop your premiums going up after a claim, as insurers use your claims history to calculate premiums, with your NCB discount calculated at the end.
Any remaining NCB you have after the claim may lower your new premium, but there's no guarantee that it'll be lower than the previous year.
What happens when I change my car or policy?
No claims bonuses can usually be transferred to another car, but if you switch insurers before the year is up, you won't get the NCB for that year.
Insurers should provide proof of your bonus at the end of your policy term. You can pass this on to your next provider when you switch.
Some insurers may provide your proof of no claims in the car insurance renewal letter they send you. If it's not there, you can call your insurer and ask them to send it.
If you cancel your policy, you have two years to reuse your NCB, otherwise, it expires and you start from scratch.
Can named drivers build up NCB?
Named drivers aren't usually allowed to build up their own NCB, as it's the main driver's good driving record that the claim-free history will be supporting.
Letting named drivers earn their own NCB could leave the system open to abuse, as you could build up a no-claims discount without ever getting behind the wheel.
There are some insurers that offer NCB for named drivers, but they can't guarantee this will be recognised by other insurers. This is, however, becoming more common.
Does NCB apply to work vehicles?
Commercial policies and fleet vehicles don't typically let you build up NCB, but some insurers will take your experience driving a company car into account when calculating your premium.
If your car is insured for you to use for "social, domestic and pleasure" purposes, as well as with work, then it's likely you can build NCB. Always check though, as each insurer is different.
How to transfer your company car NCB
If you've recently given up your company vehicle, you should be able to use any NCB built up on that car.
But the NCB is only likely to be transferable if you were named on your company's insurance policy for a particular car and for your use only.
Usually, when changing insurers, you need proof of any NCB you've built up from your last provider, but with company policies, many insurers will settle for confirmation from your employer.
Can I transfer NCB from overseas?
It's worth asking, but most UK insurers don't allow NCB built overseas to be transferred to a UK car insurance policy due to different driving laws and the administration involved.

Modeling the phase behavior of the membrane binding protein annexin V
Langmuir, Volume 18 p. 2988- 2992
The bulk thermodynamic properties of proteins originate from a varied and complex combination of interactions. We propose a simple model for the formation of ordered two-dimensional aggregates based on the interactions between pairs of annexin V molecules. Simulations of this model are shown to reproduce the experimental observations of a honeycomb (p6) and a triangular (p3) crystalline phase. The simulations indicate that the transition between these two phases is first order. While this model is extremely simple in that it relies only on hard body and short-range directional interactions, it nevertheless captures the essential physics of the interactions between the protein molecules and reproduces the phase behavior observed in electron microscopy and atomic force microscopy experiments.

Schloss Dagstuhl - Leibniz-Zentrum für Informatik
A representation of intersection types in terms of pregrammars is presented. Pregrammar based rewriting relations, corresponding respectively to type checking and inhabitation are defined and the latter is used to implement a Wajsberg/Ben-Yelles style alternating semi-decision algorithm for inhabitation. The usefulness of the framework is illustrated by revisiting and partially extending standard inhabitation related results for intersection types, as well as establishing new ones. It is shown how the notion of bounded multiset dimension emerges naturally and the relation between the two settings is clarified. A meaningful rank independent superset of the set of rank 2 types is identified for which EXPSPACE-completeness for inhabitation as well as for counting is proved. Finally, a standard result on negatively non-duplicated simple types is extended to intersection types.

Redis Output Configuration
The Redis output inserts the events into a Redis list or a Redis channel. This output plugin is compatible with the Redis input plugin for Logstash.
Example configuration:
output.redis:
 hosts: ["localhost"]
 password: "my_password"
 key: "metricbeat"
 db: 0
 timeout: 5
Compatibility
This output works with Redis 3.2.4.
Redis Output Options
You can specify the following options in the redis section of the metricbeat.yml config file:
enabled
The enabled config is a boolean setting to enable or disable the output. If set to false, the output is disabled.
The default value is true.
hosts
The list of Redis servers to connect to. If load balancing is enabled, the events are distributed to the servers in the list. If one server becomes unreachable, the events are distributed to the reachable servers only. You can define each Redis server by specifying HOST or HOST:PORT. For example: "192.15.3.2" or "test.redis.io:12345". If you don't specify a port number, the value configured by port is used.
port
Deprecated in 5.0.0.
The Redis port to use if hosts does not contain a port number. The default is 6379.
index
Deprecated in 5.0.0.
The index setting is renamed to key
The name of the Redis list or channel the events are published to. The default is "metricbeat".
key
The name of the Redis list or channel the events are published to. The default is "metricbeat".
The redis key can be set dynamically using a format string accessing any fields in the event to be published.
This configuration will use the fields.list field to set the redis list key. If fields.list is missing, fallback will be used.
output.redis:
 hosts: ["localhost"]
 key: "%{[fields.list]:fallback}"
keys
Array of key selector configurations supporting conditionals, format string based field access and name mappings. The first rule matching will be used to set the key for the event to be published. If keys is missing or no rule matches, the key field will be used.
Rule settings:
key: The key format string. If the fields used in the format string are missing, the rule fails.
mapping: Dictionary mapping key values to new names
default: Default string value if mapping does not find a match.
when: Condition which must succeed in order to execute the current rule.
Example keys settings:
output.redis:
 hosts: ["localhost"]
 key: "default_list"
 keys:
 - key: "info_list" # send to info_list if 'message' field contains INFO
 when.contains:
 message: "INFO"
 - key: "debug_list" # send to debug_list if 'message' field contains DEBUG
 when.contains:
 message: "DEBUG"
 - key: "%{[type]}"
 mapping:
 "http": "frontend_list"
 "nginx": "frontend_list"
 "mysql": "backend_list"
password
The password to authenticate with. The default is no authentication.
db
The Redis database number where the events are published. The default is 0.
datatype
The Redis data type to use for publishing events.If the data type is list, the Redis RPUSH command is used and all events are added to the list with the key defined under key. If the data type channel is used, the Redis PUBLISH command is used and means that all events are pushed to the pub/sub mechanism of Redis. The name of the channel is the one defined under key. The default value is list.
host_topology
Deprecated in 5.0.0.
The Redis host to connect to when using topology map support. Topology map support is disabled if this option is not set.
password_topology
Deprecated in 5.0.0.
The password to use for authenticating with the Redis topology server. The default is no authentication.
db_topology
Deprecated in 5.0.0.
The Redis database number where the topology information is stored. The default is 1.
worker
The number of workers to use for each host configured to publish events to Redis. Use this setting along with the loadbalance option. For example, if you have 2 hosts and 3 workers, in total 6 workers are started (3 for each host).
loadbalance
If set to true and multiple hosts or workers are configured, the output plugin load balances published events onto all Redis hosts. If set to false, the output plugin sends all events to only one host (determined at random) and will switch to another host if the currently selected one becomes unreachable. The default value is true.
timeout
The Redis connection timeout in seconds. The default is 5 seconds.
max_retries
The number of times to retry publishing an event after a publishing failure. After the specified number of retries, the events are typically dropped. Some Beats, such as Filebeat, ignore the max_retries setting and retry until all events are published.
Set max_retries to a value less than 0 to retry until all events are published.
The default is 3.
bulk_max_size
The maximum number of events to bulk in a single Redis request or pipeline. The default is 2048.
If the Beat sends single events, the events are collected into batches. If the Beat publishes a large batch of events (larger than the value specified by bulk_max_size), the batch is split.
Specifying a larger batch size can improve performance by lowering the overhead of sending events. However big batch sizes can also increase processing times, which might result in API errors, killed connections, timed-out publishing requests, and, ultimately, lower throughput.
Setting bulk_max_size to values less than or equal to 0 disables buffering in libbeat. When buffering is disabled, Beats that publish single events (such as Packetbeat) send each event directly to Redis. Beats that publish data in batches (such as Filebeat) send events in batches based on the spooler size.

Configuration options for SSL parameters like the root CA for Redis connections guarded by SSL proxies (for example stunnel). See SSL Configuration for more information.
proxy_url
The URL of the SOCKS5 proxy to use when connecting to the Redis servers. The value must be a URL with a scheme of socks5://. You cannot use a web proxy because the protocol used to communicate with Redis is not based on HTTP.
If the SOCKS5 proxy server requires client authentication, you can embed a username and password in the URL.
When using a proxy, hostnames are resolved on the proxy server instead of on the client. You can change this behavior by setting the proxy_use_local_resolver option.
proxy_use_local_resolver
This option determines whether Redis hostnames are resolved locally when using a proxy. The default value is false, which means that name resolution occurs on the proxy server.

SOR® Pivot Seal pressure switches are rugged, field-mounted instruments that incorporate a flexible modular design providing cost effective sensing solutions. The pressure sensing element of the Pivot Seal pressure switch is a force-balance, piston-actuated assembly sealed by an o-ring. As with all SOR pressure switches, the actual motion of the piston to actuate the micro switch is only several thousandths of an inch, resulting in minimal o-ring wear. Media pressure on the area of the piston counteracts the force of the range spring (adjustable by the adjusting nut screw) and moves the piston shaft and the force transmitter to directly actuate the electrical snap-action switching element.
The design of the piston/port assembly results in the device being wellsuited for a wide variety of high pressure fluid power (hydraulic) applications, especially where high-shock pressures and high-cycle rates are expected, and where normal industrial clean hydraulic fluid is used.
Basic Pivot Seal pressure switches with standard wetted parts are normally suitable for a wide variety of high-pressure fluid power (hydraulic) applications, especially where high-shock pressures and high-cycle rates are expected, and where normal industrially clean hydraulic fluid is used.
The Pivot Seal pressure switches are suitable for a wide variety of fluid power (hydraulic) applications. Specific application requirements can normally be met by selecting optional components, such as, switching elements and o-ring seal. Certain applications may require customized specials. Consult us for more information.
Note: The SOR Pivot Seal is not suitable for process applications. Refer to Pressure and Vacuum Switches for Process Applications.

عنوان مقاله [English]
One of the most important sources of drinking and agricultural water needs is rivers. One of the oldest methods of getting water from rivers that still has the greatest use is the gravity intake. In this type of intake, due to the disproportionate velocity at the upstream and downstream mouth of intake, occur flow separation and following sedimentation at the upstream mouth. In this study, by use of a numerical model (SSIIM 2.0) optimized hydraulic mode of intake, so that the minimum flow separation at the upstream mouth occurs, then similar models was performed in the physical model. Results indicated that the optimum model of numerical model and the optimum of physical model (based on sedimentation data) is the same. The optimal model is 7 in 63 cm combined arc at the upstream mouth.
Keywords: Vertical lateral intake, Flow separation, Secondary flows, Numerical model, SSIIM 2

In Ubuntu (and any other Ubuntu-based distro), when you use a "sudo" command, the system will prompt you for your password. After the first "sudo" command, the system will remember your password for the next 15 minutes so you don't have to enter any more password for subsequent "sudo" command. If, however, you feel that the 15 minutes is a bit too long/short, here is how you can change it.
1. Open a terminal and type:
2. In the file that open, scroll down till you see the line:
Change it to
Defaults env_reset, timestamp_timeout=X
where X is the time (in minutes) that the sudo password will timeout. You can set X to the value you want.
- If you set X to "-1", it will revoke the password prompt, which is not advisable.
- If you set X to "0", the system will prompt you for password everytime you use the "sudo" command
3. Press "Ctrl + x" to exit. Don't forget to press "y" to save the changes.

In astrophysics and nuclear physics, nuclear pasta is a theoretical type of degenerate matter that is postulated to exist within the crusts of neutron stars. If it does in fact exist, nuclear pasta is the strongest material in the universe.
Nuclear pasta is known as the strongest material in the universe. It is found within the crust of a neutron star. The matter there is so strong, and so heavy that it can be 10 billion times stronger than steel, and a teaspoon of this would weigh 10 million tons.

Speed Skating at the 1932 Lake Placid Winter Games
1932 Winter Games: Previous Winter Games ▪ Next Winter Games
Host City: Lake Placid, United States
Date Started: February 4, 1932
Date Finished: February 8, 1932
Events: 7
Participants: 42 (32 men and 10 women) from 6 countries
Youngest Participant: CAN Herb Flack (18 years, 220 days)
Oldest Participant: JPN Tomeju Uruma (29 years, 58 days)
Most Medals (Athlete): 4 athletes with 2 medals
Most Medals (Country): USA United States and CAN Canada (5 medals)
Lake Placid had hosted its first major speed skating competition in 1919, with the Eastern Outdoor Championships, won by local skater Charlie Jewtraw, who went on to become Olympic Champion in the 500 m at the inaugural Winter Olympics in 1924. Since then, many records had been set on the ice of the town's Mirror Lake. For the 1932 Games, a $150,000 stadium was built with a capacity of 5,000. A hockey rink was placed in the centre of the track, and matches were played between and during skating races.
Only six countries entered the speed skating events: Canada, Finland, Japan, Norway, Sweden and the host nation. However, the economic depression was not the only reason for the small number of participants. On 25 May 1931, the International Skating Union (ISU) had approved the use of the North American "pack style" system for international tournaments, as had been proposed by the American and Canadian federations. This style featured competitors starting in small groups, not unlike modern-day short-track speed skating. This meant races were decided on tactics, rather than time alone, as is common in the "Continental" style.
Quintuple Olympic Champion and reigning World Champion Clas Thunberg had experienced the North American rules first hand in 1926, and knew the North American tactics were superior. According to his auto-biography, he sent a private letter to the Norwegian federation, suggesting an alliance, but the Norwegians rejected this. (It should be pointed out, that Thunberg's biography was entitled Alone against all of Norway.) He then decided to stay away from Lake Placid, too. Both Sweden and Finland eventually sent only a single skater, compared to four skaters from Japan, which made its Olympic speed skating debut. The Dutch federation decided not to send a delegation because they did not think their skaters would stand a chance under the mass-start rules. The Norwegians did go, and even held special trials in the North American format. In the 10000 m race, Ivar Ballangrud skated 16:46.4, which was well below the current World Record of 17:17.4.
Thunberg's fear of North American domination proved correct, as US skaters won all four events, and only two medals were not taken by Americans or Canadians. In addition, controversy surrounded the events. Obstructions and violations of the rules were noted in all events, culminating in a four-country protest before the start of the 10000 m. During that competition, the results of the heats were annulled and eventually re-skated. European skaters and media spoke of a farcical affair, all skating events being decided in the last laps, regardless of the distance. The New York Times commented:
> "It was Mark Twain who once remarked that 'people often complain about the weather, but no one ever does anything about it'. In like fashion, the Europeans have been complaining about the American style of speed skating, but no one has offered a real solution."
Two-fold Olympic Champion and local boy Jack Shea suggested that a compromise might be reached by conducting the sport in several lanes, like in athletics. Nothing ever came of his suggestion.
Two weeks after the Olympic skating races, the World Championships were held at the same rink. In the absence of Olympic champions Shea and Jaffee, the Norwegians won all four individual races and the first three overall places, while the North Americans were well down in the standings. At the next ISU congress, the use of North American rules in international competitions was removed from the rule book.
Amidst all the controversy, female skaters made their Olympic debut. Three events for women had been added to the program as demonstration events, following the ISU's 1931 recognition of female skating records over 500, 1000 and 1500 m. Only American and Canadian women participated, but the races were of a high level. Winners [Jean Wilson], [Elizabeth Dubois] and [Kit Klein] posted times faster than the active World Records. Because these events were held in pack style, their times were never recognised as records. There were 10 female competitors in the events, five from Canada and five from the United States. Women would not compete in Olympic speedskating again until 1960, when it became a full medal sport.


text: We have developed a novel technique for automatically synthesizing hard real-time reactive controllers using model-checking verification. Our algorithm builds a controller incrementally, using a timed automaton model to check each partial controller for correctness. The verification model captures both the controller design and the semantics of its execution environment. If the controller is found to be incorrect, information from the verification system is used to direct the search for improvements. This paper describes how our controller synthesis process uses verification, and explains in detail how we model the execution of the real time subsystem of the CIRCA intelligent control architecture.

The score and completion status sent back to an LMS can be registered in a number of different ways
1. 'Sets course completion' option ticked in the Assessment Results asset
- If the Is tracked assessment option is checked then the score will be sent back to the LMS at the end of the assessment
- If Sets course completion is NOT set then completion from a SCORM perspective will be determined by whether the learner visits every screen in every topic in the course.
- If Sets course completion IS set then completion status sent back to the LMS will be determined by the assessment results. This can be set as either Completed or Pass/Fail in the Type of course completion dropdown.
Note that if completion is determined by the assessment then a dummy, unreachable, screen or topic should be added to the gomo course to ensure that completion isn't also triggered by the learner visiting every page.
2. Learner visiting every screen in the project
3. 'Sets course completion' action added to an interactive asset e.g. Button, Image Button

An integral representation of the displacement for problems of transient propagation of horizontally polarized shear waves is employed to investigate the diffraction of a plane wave by a crack of finite length. The stress intensity factors at small times are derived for an incident wave of arbitrary shape. For a step-stress wave the maximum stress intensity factors are shown to exceed the factors of the corresponding static problem by a factor 4 π. Brittle fracture is subsequently investigated by employing a balance of rate of energy. It is shown that for a step-stress wave the critical stress for brittle fracture is reduced by a factor π 4√2 as compared to the critical stress of the corresponding static problem. Ductile fracture is studied by assuming that yielding is restricted to a narrow band in the vicinity of the crack tips. The propagation velocity of the zone of yielding is computed and the location of the point of rupture is determined.

SQLite::VirtualTable::Pivot::Cursor - a cursor for a pivot table query
Objects in this class represent cursors for queries on pivot tables.
They maintatin a statement handle corresponding to an unpivotted query on the base table. The pivotting operation is done one row at a time, as data is returned; i.e. we order by the id, and group on the fly.
It must be possible for multiple cursors to exist at once on the same pivot table, in case it occurs more than once in a query.


When to avoid with-redefs
with-redefs is a handy clojure.core function to use when you want to redefine one or more vars temporarily (within a block) and you want these redefinitions to apply across thread boundaries
An alternative for doing something similar is with-bindings, and that is slightly different in that the new bindings are only seen within the context of the current thread. If for example, you use with-bindings on a var and the value of the var is referenced when doing a _URL_ operation say, then it is possible you won't see the temp binding, since map is lazy and may be executed in a different thread.
Also, with-bindings requires the rebound vars are dynamic.
So… with-redefs is generally a more powerful go-to tool than with-bindings?
No, with-bindings is more generally used on vars that are planned to get rebound, whereas with-redefs is intended when you want to change the way things normally work, for example when you're running a test and decide you don't really want to call an external system, and can use with-redefs to stub.
However, beware that with-redefs is not foolproof. Consider rebinding a function foo
(with-redefs [a.b.c/foo my-temp-fn]
 ... body that calls foo at some point, possibly from another thread)
Will the body here always see your temp binding?
Why not?
Well, interleaved threads is one situation.
Let's say this code is called from two threads and this is the order of events:
Thread A executes the with-redefs
Thread B executes the with-redefs
Thread A executes the body and exits the with-redefs block (thereby restoring the root binding of foo)
Thread B now executes the body and does not see the temp binding!!
The docs for with-redefs say this is handy for tests, which implies that if you want to change a var in non-test code, then alter-var-root (assuming it is done once, on startup) is the way to go.
However, there's nothing to stop you hitting an interleaving problem in tests unless you are running your tests serially and the with-redef wraps the test body. There isn't a with-redefs-visible-only-via-this-block or equivalent.
Use with-redefs cautiously. Remember this blog post when scratching your head about why some code is not seeing a temp binding.

Jean Shin: The Last Straw
Commissioned by Arts Brookfield
Jean Shin's The Last Straw presents three macro and micro views of plastic waste, featuring different configurations and perspectives of colorful straws and reflective material. A poignant part of the installation includes scattered piles of straws in the distance, which map the flow of plastic debris from our coastlines into the gigantic concentration of garbage floating in the ocean. The artwork encourages viewers to contemplate their own plastic consumption and question the ecological impact of consumer behavior in contributing to plastic pollution.
While acknowledging the Straw Ban represents only a tiny fragment of the problem in slowing down the flood of plastics into our marine environment, Jean Shin's artwork aims to prompt us to better understand the magnitude and urgency of the environmental dilemma facing our planet.
"The straw that broke the camel's back" is the familiar phrase said when a small and seemingly insignificant addition to an existing burden renders it too much to bear. What is "the last straw" in our ecological crisis? What would our future look like when we individually and collectively decide that we will no longer accept the status quo? How do we stop the first straw from being produced and get to the source of the problem?
Floating MAiZE and The Last Straw are curated by Kendal Henry for Brookfield Place. Henry is an artist and curator who has specialized in the field of public art for nearly thirty years, and the Director of the New York City Department of Cultural Affairs Percent for Art Program.

Wilkes-Barre Academy offers a peer tutoring program allowing peer volunteers to assist other students in subjects where help is needed. Tutoring may be requested by the teacher or parent, however final approval must be by the classroom teacher.
Peer tutoring is an educational approach that joins students from grades K to 4 who are tutored by older students from grades 5 to 8. Our goal is to develop skills and confidence in the subject area where help is needed.
The research literature on peer tutoring is extensive and international studies have clearly shown that peer interaction is conducive to a host of important early achievements, such as:
- children's understanding of fairness
- their self-esteem
- their proclivities toward sharing and kindness
- their acquisition of role-taking and communication skills
- their development of creative and critical thinking.
Research literature also shows that the gains for tutors often outdistance those of the students receiving assistance. These gains result from reworking what the tutors know in order to make it understandable to their students.
The benefits of peer tutoring include:
- development of reading, writing skills and language development
- development of social behaviors, interpersonal and communication skills
- improvements in self-esteem
- opportunities for leadership and social responsibility
- gaining a heightened sensitivity to younger student's needs and concerns


The recovery of kish graphite from secondary sources
by Robert Frost
Institution: University of Birmingham
Department: School of Chemical Engineering
Year: 2015
Keywords: TP Chemical technology

Full text PDF: _URL_
With the worldwide demand of graphite increasing, so the availability, cost and quality is under renewed scrutiny - with the vast majority of graphite being mined, and with these mines located in only a few significant countries, considerations of availability and sustainability have led to an increasing dependence on synthetic graphite to meet industrial needs. One potential source is 'kish' graphite recovered from the steel making process: Present within the dust produced as waste in steel plants, graphite flakes have been found in varying quantities, sizes and purity. Seven samples taken from a steel plant were analysed and tested. This testing broadly consisted of separating the kish graphite from the excess waste dust, and refining this graphite. Froth flotation was found to be an extremely effective way of achieving this, with purities of >90% being achieved from a single flotation for the larger flake sizes (>500µm). For the smaller flake sizes (<500µm), multiple froth floats were found to be needed in order to achieve the desired purity, but further complications required acid cleaning in order to achieve a >90% graphite sample. A saleable product was produced and a technical-economic assessment was made for a 10,000 tonne per year process plant.
