A set $V$ of vertices and a set $E$ of unordered and ordered pairs of vertices; denoted by $G(V,E)$. An unordered pair of vertices is said to be an edge, while an ordered pair is said to be an arc. A graph containing edges alone is said to be non-oriented or undirected; a graph containing arcs alone is said to be oriented or directed. A pair of vertices can be connected by two or more edges (arcs of the same direction) and such edges (arcs) are then said to be multiple. An arc (or edge) can begin and end at the same vertex, in which case it is known as a loop. (A "graph" is sometimes understood to be a graph without loops or multiple edges; in such a case a graph with multiple edges is said to be a multi-graph, whereas one containing both multiple edges and loops is said to be a pseudo-graph.)
Vertices connected by an edge or a loop are said to be adjacent. Edges with a common vertex are also called adjacent. An edge (arc) and any one of its two vertices are said to be incident. One says that an edge $\{u,v\}$ connects two vertices $u$ and $v$, while an arc $(u,v)$ begins at the vertex $u$ and ends at the vertex $v$. Each graph can be represented in Euclidean space by a set of points, corresponding to the vertices, which are connected by lines, corresponding to the edges (or the arcs) of the graph. In three-dimensional space any graph can be represented in such a way that the lines corresponding to edges (arcs) do not intersect at interior points.
There are various ways of specifying a graph. Let $u_1,\dots,u_n$ be the vertices of a graph $G(V,E)$ and let $e_1,\dots,e_m$ be its edges. The adjacency matrix corresponding to $G$ is the matrix $A=(a_{i,j})$ in which the element $a_{i,j}$ equals the number of edges (arcs) which join the vertices $u_i$ and $u_j$ (go from $u_i$ to $u_j$) and $a_{i,j}=0$ if the corresponding vertices are not adjacent. In the incidence matrix $B=(b_{i,j})$ of $G$ the element $b_{i,j}=1$ if the vertex $u_i$ is incident to the edge $e_j$, and $b_{i,j}=0$ if the vertex $u_i$ and the edge $e_j$ are not incident. A graph can be specified by lists, for example, by specifying pairs of vertices connected by edges (arcs) or by specifying the set of vertices adjacent to each vertex. Two graphs $G(V,E)$ and $H(W,I)$ are called isomorphic if there is a one-to-one correspondence between the sets of vertices $V,W$ and the sets of edges $E,I$ which preserves the incidence relationship (see also Graph isomorphism).
A subgraph $G'(V',E')$ of a graph $G(V,E)$ is defined as a graph with set of vertices $V'\subseteq V$ and set of edges (arcs) $E'\subseteq E$, each one of which is incident with vertices from $V'$ only. A subgraph $G'(V',E')$ is said to be generated or induced by the subset $V'\subseteq V$ if it is a graph with set of vertices $V'$ and ordered set of edges (arcs) $E'$, $E'$ consists of by all edges of $G$ which connect vertices of $V'$. A skeleton subgraph or spanning subgraph $G'(V,E')$ contains all vertices of $G$ and some subset of its edges (arcs) $E'\subseteq E$. A sequence of edges $(u_0,u_1),\dots,(u_{r-1},u_r)$ is called an edge progression or walk connecting the vertices $u_0$ and $u_r$. An edge progression is called a chain or trail if all its edges are different and a simple chain or path if all its vertices are different. A closed (simple) chain is also called a (simple) cycle. A graph is said to be connected if any pair of its vertices is connected by an edge progression. A maximal connected subgraph of a graph $G$ is said to be a connected component. A disconnected graph has at least two connected components (see also Graph, connectivity of a).
The length of an edge progression (chain, simple chain) is equal to the number of edges in the order in which they are traversed. The length of the shortest simple chain connecting two vertices $u_i$ and $u_j$ in a graph $G$ is said to be the distance $d(u_i,u_j)$ between $u_i$ and $u_j$. In a connected undirected graph the distance satisfies the axioms of a metric. The quantity $\min_{u_i} \max_{u_j} d(u_i,u_j)$ is called the diameter, while a vertex $u_0$ for which $\max_{u_j} d(u_i,u_j)$ assumes its minimum value is called a centre of $G$. A graph can contain more than one centre or no centre at all.
The degree of a vertex $u_i$ of a graph $G$, denoted by $d_i$, is the number of edges incident with that vertex. If a (loop-free) graph $G$ has $n$ vertices and $m$ edges, then $\sum_{i=1}^n d_i = 2m$. A vertex $u_i$ is said to be isolated if $d_i=0$ and terminal or pendant if $d_i=1$. A graph all vertices of which have the same degree (equal to $k$) is said to be regular of degree $k$. A complete graph has no loops and each pair of vertices is connected by exactly one edge. Let a graph $G(V,E)$ be free from loops or multiple edges; then the complementary graph to $G$ is the graph $\bar{G}(V,E)$ in which $\bar{V}=V$ and vertices are adjacent in $\bar{G}$ only if they are not adjacent in $G$. A graph which is complementary to a complete graph consists of isolated vertices and is known as empty. Many characteristics of a graph $G$ and of its complement $\bar{G}$ are related. In a directed graph $G$ one defines, for each vertex $u_i$, the output (or out) and the input (or in) (semi-) degree as the number of arcs issuing from and entering this vertex, respectively. A complete directed graph is known as a tournament. To each graph $G$ can be assigned a number of graphs which are derived from of $G$. Thus, the edge graph $L(G)$ of $G$ is the graph whose vertices correspond to the edges of $G$ and two vertices are adjacent in $L(G)$ if and only if the corresponding edges of $G$ are adjacent. In the total graph $T(G)$ of $G$ the vertices correspond to the elements of $G$, i.e. to vertices and edges, and two vertices in $T(G)$ are adjacent if and only if the corresponding elements in $G$ are adjacent or incident. Many properties of $G$ carry over to $L(G)$ and $T(G)$. Many generalizations of the concept of a "graph" are known, including that of a hypergraph and of a network graph.
With the aid of suitable operations it is possible to construct a graph from simpler graphs, to pass from a graph to simpler ones, to subdivide a graph into simpler ones, to pass from one graph to another in a given class of graphs, etc. The most common one-place operations include the removal of an edge (the vertices of the edge are preserved), the addition of an edge between two vertices of a graph, the removal of a vertex together with its incident edges (the graph obtained by removal of a vertex $v$ from a graph $G$ is often denoted by $G-v$), the addition of a vertex (which may be connected by edges with certain vertices of the graph), the contraction of an edge — identification of a pair of adjacent vertices, i.e. removal of a pair of adjacent vertices and addition of a new vertex which is adjacent to those vertices of the graph which were adjacent to at least one of the vertices which have been removed, and subdivision of an edge — removal of an edge and addition of a new vertex which is joined by an edge to each vertex of the edge which has been removed.
Two-place operations over a graph are employed in a number of problems in graph theory. Let $G_1(V_1,E_1)$ and $G_2(V_2,E_2)$ be graphs such that $V_1 \cap V_2 = \emptyset$ and $E_1 \cap E_2 = \emptyset$. The union of $G_1$ and $G_2$ is the graph $G = G_1 \cup G_2$ with set of vertices $V = V_1 \cup V_2$ and set of edges $E = E_1 \cup E_2$. The product of $G_1$ and $G_2$ is the graph $G = G_1 \times G_2$ whose set of

A: You ate this. Have you brushed your teeth?
B: You ate this. Did you brush your teeth?
Sentence A is in the Simple Past, while B is in the Present Perfect.
Which sentence is more natural?
To me, the two sentences are equally natural, but express somewhat different ideas. The first, in the present perfect, means "Have you brushed your teeth since you ate it [i.e., at any time between then and now]?". The second, in the simple past, means "Did you brush your teeth after you ate it [i.e., in the past, soon after you ate it]?".


Background New-onset diabetes after transplantation (NODAT) is an important complication after kidney transplantation. The etiology of the malady is multifactorial and includes both environmental and genetic factors. NODAT is a polygenic disease and many single-nucleotide polymorphisms could constitute potential risk factors. Peroxisome proliferator-activated receptor α (PPARα) and P450 oxidoreductase (POR) play a central role in the control of energy metabolism in humans. Some recent data highlighted a possible functional impact of two single-nucleotide polymorphisms in PPARα (rs4253728 G> A and rs4823613 A>G) and one coding variant in POR (rs1057868; POR*28; A503V) on the activity of their respective encoded proteins. In the present study, we assessed the association between these variants and the risk of developing NODAT after kidney transplantation. Methods Development of NODAT was investigated in 101 renal transplant recipients receiving tacrolimus-based immunosuppressive therapy. Patients were genotyped for PPARα and POR. The incidence of NODAT was compared between different genotypes. Kaplan-Meier and Cox's proportional-hazard analysis were used to evaluate the association of NODAT with potential risk factors. Potential nongenetic risk factors were also considered. Results The PPARa rs4253728A >G and POR*28 variant alleles were both independently associated with an increased risk for NODAT with respective odds ratios of 8.6 [95% confidence interval (CI) = 1.4-54.2; P = 0.02] and 8.1 (95% CI= 1.1-58.3; P = 0.04). Other risk predictors included sex and body weight. Conclusion This candidate-gene study shows that polymorphisms in PPARa and POR might predispose patients being treated with tacrolimus to the development of NODAT after kidney transplantation. Patient management after organ transplantation might benefit from genotype data. Pharmacogenetics and Genomics 23:649-657

Calculating Fuel Tank Capacity
If you're curious about your fuel tank capacity, here is a simple formula to determine the size of your gas tank in gallons.
Simply multiply the length, width, and height (L x W x H) of the gas tank, then divide the total by 231. 231 is the number of cubic inches in one gallon of gasoline.
There are other formulas used for cylindrical tank volumes, however, we use this formula because most Jeep gas tanks are rectangular.
One thing to note when calculating fuel tank capacity is that some tanks can hold more volume than advertised, but you should only fill it to the specified limit when you purchased the item.
For Example, a Cherokee XJ tank measuring 33 inches long, 20 inches wide, and 13 inches high will result in a 37-gallon capacity. However, you may see it advertised as a 20-gallon tank. It may also be because the tank has a pan and internal vent within, occupying space that would otherwise be occupied by gas. When determining your Jeep tank volume, you should slowly fill the tank to avoid overfilling.
Refer to our fuel system diagrams to ensure you're getting the right tank and accessories for your restoration project.

Risk Management-Frequently Asked Questions
What do I do to file a claim if university property has been stolen or damaged?
In order to file a property loss claim with the university, there are a number of things that must be done:
 1. Fill out a Property Loss Notice
 2. You must also submit the following information:
 1. Copies of invoices(and DPO if applicable) for the lost or damaged property.
 2. Copies of invoices (and DPO if applicable) for the replacement items.
 3. The police/incident report for the theft/damage, if one is available.
 4. Once you have this information, forward to:
 Risk Management
 MSC 6703
 8-7812 (phone)
 8-2878 (fax)
What information do I need to submit if damage has occured that involves repair work (building/property)?
 - You will need to submit a completed a Property Loss Notice
 along with:
 1. Invoices showing repair and/or replacement. ( NOTE: Invoices for repair must be as specific as possible in describing what repair work was done and what items were replaced in order to justify the expense.)
 2. For any labor charges the following information is needed for each person involved in the labor charges:
 1. Name
 2. Position
 3. Base pay (not including benefits, overhead, or supervisory/managerial labor)
 4. Hours worked
 3. A police/incident report if applicable.
What is the deductible amount for university insurance claims?
There is a $10,000.00 deductible for each claim.
Do I need to replace/repair the stolen or damaged property before a claim is filed?
Yes. The Division of Risk Management reimburses the university for replacement/repair cost of property losses. No claims can be filed until the lost/damaged items are replaced by the university.
Is it necessary to purchase the exact same item (model) as was stolen or damaged?
If it is at all possible to replace the stolen/damaged item with the same brand and model that was lost, you should do so. The state reimburses the university for replacement with the same model or nearest equivalent. In some cases it isn't possible to replace the item with the exact model due to discontinuation of some items. In those cases, you would need to find the nearest equivalent to the lost or damaged item(s). If you do choose to upgrade the item, instead of purchasing the same item or nearest equivalent, the Division of Risk Management will reimburse JMU for the cost of the item minus any cost for upgrading the item.
A company/institution is requesting a Certificate of Insurance from our department? Where would I get this?
Resource Management provides Certificates of Coverage. Please complete the Certificate of Coverage on-line form.
 1. The JMU department (name, MSC and phone) requesting the certificate
 2. The name and mailing address of the company or institution requesting the certificate
 3. The purpose (ie: Student Practicum, tournament game, etc.)
 4. The time period the certificate is requested for (be as specific as possible)
Once we have this information, a certificate will be drafted and the original will be sent back to your department for you to forward to the requesting company/institution.
I recently had an automobile accident while driving a university vehicle (or rental car). What should I do?
A: If you've had an accident in a JMU vehicle or rental car, while on university business. Please follow this procedure:
 1. First you need a copy of the accident report from the officer at the scene.
 2. Fill out an Automobile Loss Notice
 . This is a form that should be in every JMU vehicle. If one is not in the vehicle, or your were driving a rental vehicle.
 3. Next you need to contact our Automobile Insurance carrier,
 Crawford and Company at _PHONE_ to report the accident. Copies of the police report and the Statement of Accident will need to be forwarded to them. You should keep copies of both for your personal records.
 4. As soon as possible you should also report the accident to either Motor Pool(for JMU vehicles) or our office (for rental vehicles).
Contact Risk Management (8-7812) if you have any questions filing the claim.
Is there any way to get information on what to do if involved in an automobile accident while on university business? Our office frequently uses rental cars for university travel and we'd like to keep this information on hand for our drivers.
Risk Management has packets of information available that detail what to do if you are involved in an auto accident while on University business. Thge packet also contains a claim form, telephone numbers for various State Police divisions, Information Exchange cards, and a card for requesting help from a Passing Motorist. These packets should already be in any JMU vehicle. For those offices who would like to keep a supply of packets on hand for rental vehicles, the individual.pdf files for each of the forms/cards in the packet are available for download below.
NOTE: If you requisition a State Vehicle and find that the packet is missing, please contact Motor Pool to request one before you leave for your trip.

Destructuring array of tuples to tuple of arrays.

Destructuring arrays of tuples in Julia.
Using julia's 'dot-call' syntax on functions with multiple return arguments results in an array of tuples. Sometimes, you want the tuple of arrays instead, preserving array shape. This can be achieved using destruct, which converts an array of tuple to a tuple of arrays.
Works with any tuples (ie: with elements of different types).
This single function doesn't really require it's package, maybe you can find it a better home.
julia> using Destruct; using BenchmarkTools
julia> f(a, b) = a+1im*b, a*b, convert(Int, round(a-b)); # some transform returing multiple values
julia> v = f.(rand(3,1), rand(1,4));
julia> typeof(v)
julia> x, y, z = destruct(v);
julia> z
3×4 Array{Int64,2}:
 0 0 0 0
 1 0 1 1
 1 0 1 1
julia> v = f.(rand(500,1,1), rand(1,500,500));
julia> _USER_ destruct($v); # using BenchmarkTools
 1.396 s (7 allocations: 3.73 GiB)
Getting this out of the way:
julia> x, y, z = f.(rand(100,1,1), rand(1,100,100)) |> destruct;
A common way to unpack Arrays of tuples uses the broadcast dot-call:
unpack_broadcast(w::Array{<:Tuple}) = Tuple((v->v[i]).(w) for i=1:length(w[1]))
However, this approach suffers from two problems: it doesn't access the elements in the order they are stored in memory and has huge memory consumption for Tuples with varying types (Tuples instead of NTuples).
This "broadcast unpack" takes between 1.5x and 2x longer than destruct supplied here for arrays of NTuples. The performance gain is much larger for tuples of heterogenous types: in the 10x to 75x range, using 1/10th of the memory.
See timing scripts: timing.jl and comparative_timing.jl.
How does it work?
The destruct function uses macros from Base.Cartesian to allocate destination arrays and iterate over all the things. The alternative implementations using broadcast dot-call is available as Destruct.unpack_broadcast.

The Wage Gap between Francophones and Anglophones: A Canadian Perspective, 1970 to 2000
NBER Working Paper No. 14203
The wage differential between Francophone and Anglophone men from 1970 to 2000 fell by 25 percentage points within Quebec, but only by 10 points Canada-wide, largely because the wages of Quebec Anglophones fell by 15 points relative to other Canadian Anglophones. Accordingly, the Canadian measure of the Francophone wage gap better reflects the changing welfare of Francophones than the Quebec measure. Over half of the reduction in the Canadian Francophone wage gap is explained by rising Francophone education levels. In Quebec, the declining number and relative wages of Anglophone workers is best explained by a falling demand for English-speaking labour.

Blessed are trees

Blessed are trees
A new exhibition celebrates Canberra's woodland landscape, Sally Pryor writes.
By Writes
Jyll Bradley is momentarily stumped when I ask her to name her favourite treescape in Canberra.
Over the past three years, she has been back and forth between England and Canberra four times, and has spent, all up, almost six months here in the capital. Her preoccupation during her visits here has been, primarily, the trees - Canberra's tree layout, the people who planted them, the residents who love them, and the atmosphere they create. It's all part of a major art project commissioned as part of the city's Centenary celebrations; three years in the making, the multi-disciplinary display opens at the National Library this week.
British Artist Jyll Bradley was commissioned by the Centenary to create an installation City of Trees at the National Library, Canberra.

Its content has been kept under wraps until now, but its premise is simple: every tree has a human story to tell, and this is particularly the case in Canberra. The city grew up out of one million trees planted in what was once compared to a sheep paddock, and which now, 100 years later, is more like a forest with a city emerging through it.
And whether they know it or not, every resident of Canberra has a favourite treescape, even if they associate it more with the quality of the light that shines through the naked boughs of an inner-northern suburb in winter, the shade cast by an apple tree in the garden, or a strand of pines glimpsed on the parkway between Tuggeranong and Civic.
Think hard, and you'll work out which it is. After a moment or two, Bradley, who, after all, has made it her business to learn as much as she can about Canberra's trees, realises that she, too, has a favourite.
''I think mine are the York oaks just up by the Parliament,'' she says, referring to York Park oak plantation in Barton.
''I think that's a really profound space, where you see those lines of oaks and then when you look into it and research it, you talk to people and see how interesting it is in terms of the British trying to put the roots of democracy into Australia through the roots of the oak.''
Bradley - a soft-spoken Englishwoman - is not just betraying her allegiances; the York oaks do have a good story attached. The first in the park was planted, symbolically, by the then Duke of York in 1927, to mark the opening of Old Parliament House. More oaks were added during the Great Depression to create jobs for the many unemployed.
The historic plantation was neglected over the years and fell into disrepair; in 2004, Parliament House architect Romaldo Giurgola was invited to design a new landscape for them, which opened in 2011.
''And then the whole change of how life moves on and politics moves on, and people are still fighting. The staunch republicans I met were fighting for those oaks, even though they represent these indelible ties to the UK,'' she says.
''And also the fact that they're English oaks but with an Australian accent - they don't look like English oaks, they don't behave like English oaks at all.''
And she should know, of course. The London-based artist is the daughter of a forester and has long had an affinity with trees. When she met Robyn Archer several years ago in Britain, the creative director of the Centenary invited her to visit Canberra and respond to what she saw. Having never visited Australia before, and knowing next to nothing about Canberra, the first thing she noticed as she flew into the city was the landscape created by the trees.
Now, three years down the track, City of Trees, her multifaceted installation, is set to open. Giurgola is featured in there, reading poetry at the inauguration of the revitalised oaks, along with numerous other Canberra voices to add to the trees' presence.
She says one of the most satisfying aspects of the project has been the different people she has met along the way.
''This is my fourth trip, and in total I've probably spent about five or six months in Canberra. I know the trees, and more importantly, I know why the trees are here,'' she says.
''I think what's great about the whole project is that I've been able to meet people from so many different walks of life, for whom trees mean very different things. Aldo Giurgola will talk about how architecture makes form and trees make space, so he's really interested in how trees create space within a city. Then you'll talk to someone like a forester and they'll be talking about whether it's deciduous or whether it's evergreen and who planted it and why and the history of it. And then other people will talk about the spiritual side of it, so I've tried to capture all that, as well as the founding part of it.''
Showing the installation in the National Library is also a play on the theme.
''It's such amazing honour to show in a national library of a country, it's probably the highest honour for me, especially because I'm also a writer,'' she says.
''What I've really thought about as well is the space of the book, because books are made from many leaves which in turn is made from wood, from paper, and so you'll find in the exhibition lots of references to printing, to paper, to books. In a way you could say that you could read the exhibition … it's like entering the imaginative space of a book.''
All in all, visitors can expect ''a very kind of immersive and contemplative exhibition''.
''It's not your usual exhibition where there's stuff on display and it's sort of in a space. What I've tried to do is construct and create a space that will show the work and create a particular kind of atmosphere of contemplation, emotion, intrigue.''
It's the first time she's created an entire body of work clustered around a central theme. But the theme itself is multifaceted.
''It's not about trees - it's to do with the space that trees create,'' she says.
''I think trees create different spaces in life. They create a practical space in terms of architecture and how we move around the city. They also create an emotional space, they create a spiritual space … and imaginative spaces as well, and in that regard I'm trying to echo that sentiment, if you like, within the exhibition.''
The show runs until October, and Bradley hopes visitors will spend more than a few minutes in the space.
''I say take time, book a couple of hours out of your busy life, come and spend time in the space, and it will be very, very rewarding.''
City of Trees is at the National Library until October 7.

Comparison of the Navy Working Capital Fund and mission funding as applied to Navy shipyards [electronic resource] /
Abstract (Summary)The dramatic political and economic events, both globally and within the United States, during the early 1990s led to significant changes to the Navy shipyard organizational structure. As part of the Navy maintenance regionalization and consolidation program, the financial management system used to manage these commands has been changed. Specifically, the Navy has shifted two of its four shipyards, with authorization to shift the other two in FY07, from the Navy Working Capital Fund to mission funding through direct congressional appropriations. This funding shift has raised questions about the advantages and disadvantages each financial system provides shipyards, the operating differences that occur due to the funding change, and the future financial consequences of funding Navy shipyards using direct appropriations. This thesis identifies the advantages and disadvantages of the Navy Working Capital Fund and the mission funding model in the context of a Navy shipyard environment and determines whether the change in financial structure provides an overall benefit that should be pursued for all shipyards.

Statement of Significance (as of designation - April 11, 1989):
The world's only surviving four-masted, full-rigged ship, FALLS OF CLYDE (1878) is the oldest surviving American tanker and the only surviving sailing oil tanker left afloat. Built during a shipbuilding boom inspired by increasing trade with the United States, the ship made several voyages to American ports while under the British flag. Sold to American owners in 1898, it gained American registry by a special act of Congress in 1900. Henceforth she was involved in the nationally important Hawaiian trans-Pacific sugar trade and later in transporting petroleum as a bulk cargo carrier.

Monday Notes: We had some IU student teachers visiting our classroom this morning. They helped with our Reader's Workshop. We talked about Four Feet, Two Sandals at our table groups. Then the Indian School group met and talked about Raven's brother getting sick in Chapter 5. After that, we worked on writing ADJECTIVES in short pieces about our favorite instruments. After lunch, we visited our first grade buddies. At math, we learned about measuring angles. It was tricky, but we're getting the hang of it. Then we started designing "geo-monsters," using our math templates.
Friday Notes: In the morning we listened to our new podcast. It was great, awesome and terrific! Our goal is to get 30 comments this week! We already have 7! We read a book about a girl who was born in Afghanistan. They had many wars there. Now she lives in the U.S. We did science experiments with Mrs. Streib's class. What a wild week!

Tuesday Notes: Today was a big day in 306 and in HISTORY! Our third graders were in the Herald Times! After we read about ourselves in the newspaper, we checked out the Dr. Martin Luther King, Jr web pages created by Mrs. Streib's class and Mrs. Ritchey's class. Both classes were winners in the web page contest by MCCSC. Then we read a book about Dr. King called Martin's Big Words. We made a poster of some of Dr. King's important words and messages. We ate lunch together in our classroom and watched President Obama take the oath of office. We took notes during his inaugural speech and then we made a poster called Barack's Big Words. We also read a picture book about President Obama's life. Mr. Combs was our awesome speaker at our Dr. King convocation. It was a great day to be together and learn more about our country and our government.
Wednesday Notes: Today we welcomed our new gym teacher, Ms. Uchman to Fairview. We had a great time at gym and art first thing this morning. We worked in our reading sketchbooks and learned more about inferences. We learned about equilateral, isoceles and scalene triangles. We worked on SOUND experiments during science class. When we put the tuning fork into water, it splashed. When we touched the tuning fork to paper, it buzzed. When we touched it to the ping pong ball, it bounced back and forth. A wonderful day in 306.
Thursday Notes: Our travellers have returned! Today was busy. After a lesson about adjectives, we worked on writing this morning. We made SIGNS about our book, Listen To the Wind. After recess, we worked on literature circles. The Stone Fox group met and talked about Little Willy's feelings about Stone Fox. We learned about QUADRANGLES in math class. We are loving the HUGO CABRET book by Brian Selznick!
Monday, January 12th, 2009
Monday Notes: Wow! This day was busy! At Reader's Workshop, we used the dictionary to look up our vocabulary words. Then we illustrated a passage from a book to show how we visualized the details. We had literature circles too. We watched a program about PRONOUNS and found all the pronouns in a song called, "The Girl Is Mine!" After lunch, we worked on PARALLEL and INTERSECTING lines. Ms. Streib's class visited and we worked on finishing up some of the pages in our Monroe County History books. Great news! Tammi and Allijah worked on an essay contest at Banneker Center at the View. They won and are going to travel to Washington to see the inauguration! WOW!!!! Congratulations!!!!

Abstract: This paper studies both theoretically and empirically the impact of using trade as a peace instrument to avoid an anticipated interstate conflict between countries disputing a historical territory. The impact of trade is examined through the role of organized interest groups in influencing their governments' foreign policies. A game theoretical model is used to observe the dynamics at the domestic and international level of negotiating a peace agreement that can be accompanied with a trade agreement. Using backward induction, I find that the probability of conflict depends on the contribution schedules offered by organized interest groups, weighted aggregate welfare, and military cost. Using the linear probability model with fixed effects, I test the model empirically. The main result is that the probability of an interstate conflict is lower when the government adopts trade liberalization policies in export-oriented industries while protecting import-competing industries. This indicates that organized interest groups are key when it comes to using trade to dampen conflicts.

I'm just going through the original book by Anosov, where he tries to proof this result. I don't quite understand it.
So let $\phi_t:TM\rightarrow TM$ be a geodesic flow on a compact surface $M$ of negative curvature. Let $\theta=(x,v)\in TM$, then there exists an isomorphism $T_\theta TM\cong T_pM\oplus T_pM$
So how can we find stable and unstable directions and show that vectors in this direction contract or expand exponentially, as it is required by an Anosov flow?
First of all, I understand that the direction of the flow itself is invariant and the phase velocity stays constant there. Then I have also understood that a vector $\xi=(\xi_h,\xi_ v)\in T_pM\oplus T_pM$, that is transversal to the flow direction will have a length that is convex for all $t$, i.e. \begin{equation} \frac{d^2}{dt^2}\Big|\;\xi\;\Big|^2>0 \end{equation}
But how do we conclude the existence of contracting and expanding directions from this?
What is your approach? Sometimes I have seen people using Jacobi fields. But I don't know how to do that?
Thanks in advance
btw. do you know how to show that the geodesic flow on $M$, as above, has no conjugate points?

This policy guide note synthesises the findings of the final report for RP3038: Lower Income Barriers to Low Carbon Living. In summary:
- Broad engagement with lower income households, industry, government and other stakeholders reveals that energy deprivation is an increasing problem in Australia which impacts upon the social wellbeing of communities.
- There are a wide range of financial and non-financial barriers limiting the ability of lower income households to address energy deprivation.
- The government's approach to energy and support mechanisms varies from state to state and nationally, further exacerbating the problem.
- We present a range of policy recommendations across three categories, namely information provision, financial assistance, and regulatory controls.
RP3038: Lower Income Barriers to Low Carbon Living


Husaby church with its impressive triple spire dating from the 11th century is Sweden's first bishop's church and one of the oldest buildings in Sweden today.
The interior of the church still has a medieval atmosphere. The font and triumphal cross inside the church date from the 13th century, as does the bishop's chair, which is one of the oldest pieces of Swedish furniture.
Husaby is best known for the fact that Olof Skötkonung was baptised here around 1000 CE. He was the first Christian king of Sweden. He ruled from the 990s until his death in 1022, and is said to have been the first king to rule over both Svealand and Götaland.
Next to the church we can see the remains of the bishop's castle. The castle was probably the royal farm of Olof Skötkonung, and later became the Husaby residence of the bishops of Skara, until the start of the Reformation in 1527. The castle has undergone several stages of reconstruction. The oldest part probably dates from the 12th century, but there are remains that are considerably older.

Is there a difference between linear array 3dB beam width and linear array bearing resolution?
 - $\begingroup$ A little more context is suggested to help readers answer your question $\endgroup$ – Laurent Duval Apr 6 '17 at 12:22
The answer will be NO, but to be precise especially in case of conventional beam forming.
Theoretical Derivation
The antenna electric field pattern of array antenna can be given by
where N is the number of antenna elements
d is the spacing between antenna elements
In order to find the beamwidth (3 dB), the above equation should be equated to and solve for
The solution will come to be as
where D is the total aperture distance and can be approximated as
For spacing of the equation simplifies and can be approximated as
Thus beam width of planar antenna can be represented as
Angular Resolution Using FFT Over Antenna Elements
In order the prove the lemma that the angular resolution obtained by performing the FFT across antenna dimension equals to the beamwidth of the antenna array, we have to obtain the angular resolution using FFT.
The below diagram shows the frequency obtained due to path difference between the antenna elements which occurred due to the angle of arrival other than the broadside angle
enter image description here
The frequency resolution using FFT can be represented as where N is the number of samples but in our case it is equal to number of antenna elements.
The angular resolution can be found by equating the difference in frequency of different angles and
The frequency resolution becomes:
Solving we get and if we put and we get the same resolution as the beamwidth i.e
Thus for summarizing the above discussion using FFT we can only achieve the max angular resolution equals to the beamwidth of the antenna array which is equal to angular resolution = antenna array beamwidth = 2/N
Kindly note that this equality is true for the case of conventional beam forming only, there exist also some advance beam former where your angular resolution is better than the 3db beam width
This is the same answer which I provided on ULA beamwidth and angular resolution, might this will be helpful.

A MAN needed to have the end of his penis amputated after doctors spotted that it was rotting away during a routine check-up.
The 43-year-old patient, who hasn't been named, was having dialysis treatment for kidney failure at a hospital near Adelaide, South Australia.
But during his examination, medics noticed that the end of his penis had turned white with black spots.
Surgeons quickly realised that it was gangrenous and the dead flesh needed to be sliced off urgently to prevent it from spreading.
Writing in an article, published in BMJ Case Reports, medics explained that the man had developed a rare disease called penile calciphylaxis.
It's a build up of calcium deposits in the small blood vessels, causing them to narrow and cut off circulation.
This can lead to the tissue dying and if it's not caught quickly, it can cause gangrene which can spread quickly and is incurable.
Calciphylaxis can be caused by chronic kidney disease because the organs stop filtering the calcium out of the blood.
Lucky to be alive
In this case, the medics, led by Dr Rowan David, said that the man was lucky to have survived the condition, which kills around six in 10 patients.
He wrote: "The majority of patients who develop penile calciphylaxis progress to gangrene and sepsis".
The patient was taken for an emergency operation to remove the rotting flesh but his wound got worse and he needed further surgery to remove the entire tip.
They managed to reconstruct it with a skin graft four days later but he was left with what they described as a "penile stump".
Despite his ordeal, the man appeared to be doing well when he returned for his two-month check-up.
What is calciphylaxis?
Calciphylaxis is a rare, but serious, kidney complication.
The condition causes calcium to build up inside the blood vessels of the fat and skin.
Calciphylaxis is also called calcific uremic arteriolopathy.
It's most often seen in people with advanced chronic kidney disease, or people with kidney failure who are on dialysis or have had a kidney transplant.
In dialysis, a machine filters and purifies the blood because the kidneys are unable to do so on their own.
Calciphylaxis results in the formation of very painful skin lesions. It often causes serious infections that can be fatal.
Symptoms of calciphylaxis include:
- body aches
If you have any concerns, see a GP immediately.
MORE ON HEALTH
However a year after the operation he was back for more emergency surgery - this time for a perforated bowel.
Medics said this was as a result of calciphylaxis developing in other parts of his body, including his large intestine.
They wrote: "The patient remains alive at his last follow-up over a year following his initial diagnosis of penile calciphylaxis."


»Vti vishi kakor ta odsgoraj«
 - Zmaga Kumer
In the majority of older Slovene song books, only the texts are published and a note added stating that the poem is to be sung to the tune of some other well known song. The publishers have availed themselves of the fact that in folk-songs text and melody are not inseparable but are at times inter changable. (Example I) It appears that the exchange of two melodies sometimes depends on similarities in the beginnings of their respective texts. (Ex. II), provided they are based on the same metric pattern or that their text is such that the metre can be interpreted in various ways according to the peculiarities of the Slovene language, in which the accent is mobile. (Ex. III). Under the same conditions, one melody can be used for songs having different contents and functions, whether they come from the same region or from different regions, with corresponding variations. (Ex. IV–VI) In answer to the question whether any given song has its own particular melody, three songs are quoted, aech with its most characteristic melody, which is found linked to the same text even in places that are geographically widely separated. (Ex. VII–VIII).

Cross posted from stackoverflow at the suggestion of a commenter.
I have a series of CSV files of timestamped coordinates (X, Y, and Z in mm). What would be the simplest way to extract motion data from them?
The information I'd like to extract includes the following:
 - Number of direction changes
 - Initial acceleration of the first and last movements
 - Bearing (angle) of these movements
 - Average speed whilst non-stationary
Ideally, I'd eventually like to be able to categorise patterns of motion, so bonus points for anyone who can suggest a way of doing this. It strikes me that one way I could do this would be to generate pictures/videos of the motion from the coordinates and ask humans to categorise them - suggestions as to how I'd do this are very welcome.
A complication is the fact that the readings are polluted with noise. In order to overcome this, each recording is prefaced with at least 20 seconds of stillness which can serve as a sort of "noise profile". I'm not sure how to implement this though.
If it helps, the motion being recorded is that of a persons hand during a simple grabbing task. The data is generated using a magnetic motion tracker attached to the wrist. Also, I'm using C#, but I guess the maths is language agnostic.
There is a bounty open on the original question, so feel free to post your answers there as well as here.

If I were modeling this, I would treat the initial point in the file as the displacement relative to the some fixed point and each subsequent point as a displacement from the previous point. In this way, you effectively end up with a sequence of vectors that can be reasoned over using standard methods from vector analysis. That is, the points in the file $\{p_0, p_1, \dots p_n\}$ yield the sequence of vectors $\{v_0 = p_1, v_1 = p_1 - p_0, \dots v_n = p_n - p_{n-1} \}$. Using these vectors you can then find the angle between them, determine the average speed, etc, according to elementary formula. As for dealing with noise in your data, I can't comment much on that other than to note that it might be helpful to introduce a notion of tolerance similar to that which is introduced to determine whether two floating point numbers are "equal". If the magntitude of displacement between point $p_i$ and $p_j$ is less than some tolerance value $\epsilon$ and/or change in direction also falls within a certain level of tolerance then perhaps it can be ignored. There are of course much more sophisticated statistical techniques that can be employed that I'm not really qualified to explain.

Application of aqueous primary cholesterol standards for enzymatic assay of cholesterol
Article (Published version)
MetadataShow full item record
Cholesterol standards prepared as aqueous solutions with Triton X-100 are applied to cholesterol determination by enzymatic test-reagents of Radonja-SDK and Behring, based on the CHOD-PAP method. The measured absorbances at 500 nm plotted against the concentrations of cholesterol standards gave calibration curves with the equations: Y(x) = 0.007235 + 0.066450x, r = 0.99991 for SDK and Y(x) = 0.001348 + 0.063463x, r = 0.99968 for the Behring test. The accuracy of cholesterol content determination in each standard is evaluated by comparison of specified standard concentrations (X) against the values calculated by factor 14.7 (N(x) = 0.19396 + 0.95865x, r = 0.99992) and 15.1 (N(x) = 0.019396 + 0.95865x, r = 0.99968) for the SKD and Behring tests, respectively. The comparison of cholesterol values in 40 different sera calculated via calibration curves and by corresponding factor showed a high correlation (r ≥ 0.999). The standards used as a sample gave a high precision of assay (KV ≤ 3.25%...). The aqueous cholesterol standards were stable for 5 months at +4°C.

The pom-pom anti-aircraft gun, so-called because of its characteristic sound when firing, was fitted to most Canadian corvettes during the Second World War.
Designed to counter low-flying aircraft, the pom-pom could also be used against surfaced submarines. Canadian manufacturers built hundreds of these guns during the war. Dominion Bridge Company manufactured this one in 1942, while the Canadian Locomotive Co. of Kingston, Ontario, made the mounting. Both were fitted to the corvette HMCS Kamloops, which appeared in the 1943 film Corvette K-225.

A pianist from the UK played classical music to soothe hungry monkeys in Thailand - watch the video
Tuesday, 24th November 2020, 4:03 pm
Updated Tuesday, 24th November 2020, 4:05 pm
Coronavirus restrictions around the globe have resulted in places usually packed with people being left deserted, especially those frequented by tourists.
The effect of no regular visitors has been seen in Lopburi, Thailand, where wild macaque monkeys are normally fed by those visiting the province, usually at the ancient site of Phra Prang Sam Yod - aptly known as Monkey Temple.
But one local human resident has found a way to soothe the hunger of the crab-eating macaques - also known as long-tailed macaques.
Raising awareness of the hunger of the macaques
UK born pianist, Paul Barton, who now lives in Thailand, has been playing the piano to the monkeys as a way of soothing them from their hunger.
He said, "It's possible that the music can play a part of the rehabilitation process."
The pianist has been playing Greensleeves, Beethoven's Fur Elise, and Michael Nyman's Diary of Love to the monkeys - some of which climb on his head as he plays.
Mr Barton said he hoped his concert would raise awareness about the monkeys' hunger during the pandemic, adding, "We need to make an effort to make sure that they eat properly. And when they eat properly they will be calmer and will not be aggressive."
Prior to playing music to monkeys, the pianist played the likes of Bach, Schubert, Chopin and Beethoven to elephants at retirement sanctuaries for more than a decade.
How long have the monkeys been in Lopburi?
Phra Prang Sam Yod was constructed in the 13th century in a heavily forested area, and when the city continued to gradually expand around the temple, the monkeys remained.
It's believed that locals didn't mind the presence of the monkeys, as the macaques were believed to be living representatives of the Hindu god, Hanuman, and seen as being symbolic of good luck.
However, their population has continued to grow, with it calculated that, as of the end of September this year, there are over 9,000 macaques in the province of Lopburi.

 You could remove it but part of the meaning would be lost. "ci" shows some kind of proximity (in space and/or in time) in regard to the person speaking.
 In context, it can mark a contrast between a previous time (that would be "cette fois-là") when the woman wasn't "contente".
 So the speaker asks if she is satisfied this time, in opposition to the other time when she was not.
 The English equivalent would be:
 Cette fois-ci = This time here
 Cette fois-là = That time there
 (even though in English it is very rare to speak like this, this type of specification is common in French)

Let's say that you are given a SQL table called "Compare" (the schema is shown below) with only one column called "Numbers".
Write a SQL query that will return the maximum value from the "Numbers" column, without using a SQL aggregate like MAX or MIN.
This problem is difficult because you are forced to think outside the box, and use whatever SQL you know to solve a problem without using the most obvious solution (doing a "select MAX…" from the table).
Probably the best way to start breaking this problem down is by creating a sample table with some actual data that matches the schema given. Here is a sample table to start out with:
The value that we want to extract from the table above is 90, since it is the maximum value in the table. How can we extract this value from the table in a creative way (it will have to be creative since we can't use the max or min aggregates)? Well, what are the properties of the highest number (90 in our example)? We could say that there are no numbers larger than 90 – that doesn't sound very promising in terms of solving this problem.
We could also say that 90 is the only number that does not have a number that is greater than it. If we can somehow return every value that does not have a value greater than it then we would only be returning 90. This would solve the problem. So, we should try to design a SQL statement that would return every number that does not have another number greater than it. Sounds fun right?
Let's start out simple by figuring out which numbers do have any numbers greater than themselves. This is an easier query. We can start by joining the Compare table with itself – this is called a self join, which you can read more about here in case you are not familiar with self joins: Example of self join in SQL.
Using a self join, we can create all the possible pairs for which each value in one column is greater than the corresponding value in the other column. This is exactly what the following query does:
SELECT Smaller.Numbers, Larger.Numbers FROM Compare as Larger JOIN Compare AS Smaller ON Smaller.Numbers < Larger.Numbers
Now, let's use the sample table we created, and we end up with this table after running the query above:
Now we have every value in the "Smaller" column except the largest value of 90. This means that all we have to do is find the value that is not in the Smaller column (but is in the Compare table), and that will give us the maximum value. We can easily do this using the NOT IN operator in SQL.
But before we do that we have to change the query above so that it only selects the "Smaller" column - because that is the only column we are interested in. So, we can simply change our query above to this in order to get the "Smaller" column:
SELECT Smaller.Numbers FROM Compare as Larger JOIN Compare AS Smaller ON Smaller.Numbers < Larger.Numbers
Now, all we have to do is apply the NOT IN operator to find the max value.
This will give us what we want - the maximum value. But there is one small problem with the SQL above - if the maximum value is repeated in the Compare table then it will return that value twice. We can prevent that by simply using the DISTINCT keyword. So, here's what the query looks like now:
And there we have our final answer. Of course, some of you may be saying that there is a much simpler solution to this problem. And you would be correct. Here is a simpler answer to the problem using the SQL Top clause along with the SQL Order By clause - this is what it would look like in SQL Server:
select TOP 1 -- select the very top entry in result set Numbers from Compare order by Numbers DESC
And since MySQL does not have a TOP clause this is what it would look like in MySQL using just ORDER BY and LIMIT :
select Numbers from Compare order by Numbers DESC - order in descending order LIMIT 1 --retrieve only one value
So, even though there are a couple of much simpler answers it is nice to know the more complicated answer using a self join so that you can impress your interviewer with your knowledge.

Rotation for RBXDevs-How to Fix Wood Grain
Hello confused devs of ROBLOX, WoodReviewer here. Today I am not here to just talk about how wood grain should go. Today I am only here to talk about how you rotate wood grain to fix it. Yes, I know. You just rotate and resize the bricks. But that seems to be above what some people are able to do. So lets start at the very basics on how you fix wood grain.
No Plugins
This first part is how you can fix wood grain with a completely stock version of ROBLOX studio, no plugins or anything, like I use to do for years before newer building plugins were a thing. The first step is to have some bad wood grain.
Bad Grain.png
The second step is to change the wood grain to wooden planks.
bad grain planks.png
Why? Simply put, wooden planks and regular wood have the same grain direction, and with the darker lines provided by the gaps between the planks, it can be easier to tell what way the wood grain is facing.
Step two isn't a step as much as making sure you do everything right. Simple check the size of the brick you are fixing.
There are several ways to do this, either in notepad, sticky notes, mental notes, or making a duplicate brick and putting it some where to act as a reference point.
Size Notepad.png
Next up is another option step in case you can't tell what way the wood grain is facing. First, you need to resize the brick.
Resize Planks.png
But don't resize it all at once; do one side first.
Resize Planks 2.png
Then the other side an equal amount. The ensures the center of the brick stays in the same exact place while rotating the brick.
Resize Planks 3.png
And then resize the other two sides the same way. Again, this is optional, only do it if you can't tell what direction you need to rotate the board for proper wood grain.
Final Planks Resize.png
Next up you need to rotate the wood. Studio normal rotation amount means that that it should go an even 90 degree rotations, but if it does not change your rotation amount so it can do an even 90 degrees.
Planks Rotate.png
Next is a game of guess-and-check. Rotate the wood until it is finally at the correct orientation. This can vary based on how the wood was originally.
Planks rotations.png
From here, simply resize the brick so it is back to its original dimensions. Remember, to keep the brick in the same position you need to rotate each side by equal amounts. So in this case, it was 3x3x7. To make it be 1x1x7, you need to resize the longest side by 3 studs each, and the short side by 1 stud each. Then to fix its height, raise the top and lower the bottom by 2 studs each.
Resize final.png
Then, in the last step, change it back to wood if that is what you want, and voila, proper wood grain.
Back to wood.png
Next up is a slightly easier way to fix wood grain, but requires a plugin. Personally I prefer CmdUtl or one of its derivatives, such as Studio Build Suite, but any plugin that will let you rotate objects and resize from center should work. This is what I will be working with, a dozen or so bad pieces of wood grain. This can be fence posts, railings, chair legs, or anything that is repeated and exactly the same.
Bunch of parts.png
First you need to select them all. You can either alt+right click on each, select them in explorer, use a selection plugin, or drag and select them. I used the latter since there was nothing else I could accidentally select.
Next open up your building plugin.
From here, repeat the above steps, with some minor differences. First write down the size of the parts. Then, when you go to resize them to make the wood grain larger, use the "Resize Center" button. This will resize them from the center of the brick, so resizing by.5, for example, will increase both sides by.25 studs. This helps ensure the center of the brick remains in the same place.
SBS Resize Center.png
For most CmdUtl derivatives, this does it for every brick. Again, make sure your building plugin can do this. Next, you need to rotate them. Again, similar to the default studio steps, only this time use the "Rotate Object" tool. "Rotate Object" will rotate each object in price, while "Rotate Group" and "Rotate Pivot" will rotate the objects as a group, moving most of the bricks.
SBS Rotate Object.png
Then just keep repeating until they are in the correct orientation.
SBS Correct Rotations.png
And then resize them, again resizing from center so they remain in the exact same spot. Once the size is correct, simply change the material and it is done.
SBS Resize Final.png
Even though most people will want to use the Material Flip plugin, mass-fixing 100 or so bricks this way is much quicker than using the Material Flip plugin at times.
Material Flip
Next up is the simplest way. First, install and enable the Material Flip plugin by Stravant. Next open select it in studio and look at a brick in studio with bad wood grain.
Texture Flip Front.png
The click on it and that face will have the material flipped 90 degrees.
Textue Flip Front Result.png
Repeat until all sides are fixed. This usually requires 2 clicks per brick, but sometimes fixing one side will cause the orientation of the brick to change in the way that both sides are fixed at once.
Texture flip side result.png
Seriously, why did I feel the need to do a tutorial on how to use this plugin.
Control Panel
Next up is not a way to fix wood grain, but a way to select it. It is Studio Command Panel, and is a quick way to select multiple bricks. Once you select the bricks you want, you can then rotate and fix them with CmdUtl, whether it is 5 bricks or 5,000 bricks. After you install it, click on it to activate it, select a brick, and press "P". This will open in up the panel.
Control Panel.png
Then just type in a command. For this, I'll be using the "SelectSimilar" command. First up is the "Similar Appearance" selection. It shows up once you type "SelectSimilar". "Similar Appearance" selects any bricks that have a similar color and material to the original brick, in this case the one on the far left. Because one brick is green, it is not selected.
Control Panel Appearance.png
Next up is the "Material" command. This will select all parts with a similar material, so the green one is selected. If you know all the wood in a place is incorrect, you can use this command.
Control Panel Material.png
Next up is color. Like appearance, it selects bricks based on color, but ignores material. In this case, it ignores the green brick again. I find this most useful because you can tag parts in a place you want ignored odd colors, like bright pink or green, and the selection will ignore them if they are good.
Control Panel Color.png
Next is by size. It ignores color and material, and only selects based on size. This is useful since when you go to fix the wood grain with CmdUtl you need the parts to be the same size, but it is not the most useful option.
Control Panel Size.png
The most useful selection tool is all. It only selects parts that are the same size, material, and color. This is the most useful because it can ignore non-wood parts, only select similarly sized parts, like size, which is needed to fix wood grain, and you can tag parts you want ignored with different colors to, well, ignore them.
Control Panel All.png
This plugin is very powerful and can do many things. However, all I use it for is to select stuff, so that is all I have experience with.

 Thank you so much. Now I realize why my wood grain was off and why you keep criticizing the wood grain even though I didn't quite understand what was wrong with it.

City of Alexandria, VA
History of the Alexandria's Human Rights Code
On March 25, 1975, Alexandria City Council passed one of the first human rights ordinances in Virginia.
The Code, which became effective April 21, 1975, prohibited discrimination in employment, housing, public accommodation, credit, health and social services, education and city contracts on the basis of race, color, sex, age, religion, national origin, ancestry, marital status, or physical handicap.
Throughout the years, a number of changes have expanded the reach of the Code. In 1988, the Code was amended to include sexual orientation as a protected class; in 1991, the Code was amended to include fair housing protection for families with children, and the protection for the "physically handicapped" was expanded to cover all disabilities. Last, amendments to the Code in 1996 prohibited discriminatory practices in commercial real estate.


How Statistics Homework Determines The Photographer's Future
Photographer's Future
Remember the first time your kids took some shots with your camera phone. It was their first time and of course, they are not professional photographers. But guess what these are signs they will make good photographers in the future.
It might sound absurd but statistics does determine the future of the photographer. A good photographer will do well with the sound knowledge of statistics or other subjects involving calculations. This is why people can pay for statistics homework just to see the results. Let's find out how.
 1. Understanding the Rule of the third
A good photographer would obviously need a sound knowledge of statistics to excel. Take a look at the photos you have at home. Aren't they looking great? There is one formula that makes it possible to determine if something is great to the human eye. It is known as the rule of thirds.
The rule in question is simple to understand and also needs some statistical knowledge. You can have a pleasing composition of the image if this rule is applied well. The photographer's duty is to make sure that points of interest are placed along the lines of a grid of nine. This is also the area where the picture is shared into three main parts; vertically and horizontally. The view should also be divided fast.
The complex calculations in statistics are one of the reasons students dump statistics homework. Most of the calculations are abstract and difficult to understand. But if your dream is to become a professional photographer in the future, there is no point in running away from your statistics homework. It is very easy to find online help with statistics no matter how complex the homework is.
Writing service providers like have made things a lot easier for students to pass statistics assignment and broaden their understanding. They are written by experts who have sound knowledge and qualification on statistics.
 1. Making Use of the Camera
Pressing the green circle on the screen of the phone is what is used to take pictures. But there is more a professional photographer need to understand. The Single-lens reflex camera (SLR) is what the professional photographer uses. And to be effective, they need to know a thing or two about the depth of field and shutter speeds which will also involve sound statistical or mathematical knowledge. The shutter speed is used to determine how fast the camera blinks. The aperture, on the other hand, controls the amount of light that comes in.
As a photographer, one also needs to have a basic understanding of geometric sequence to determine the correct shutter speed. Calculations on shutter speed are in fractions of seconds. So photographers should be sound with calculations.
Most statistics homework is complex and difficult to understand. But students can seek statistics online help whenever they encounter challenges with their homework. There are dozens of professionals online who are willing to assist students to get good grades on their statistics assignment. So, if you want to become a professional photographer in the future, embrace statistics.

Homemaker Figures were the figures used to represent people within various Homemaker sets from 1974 through 1982. They are comprised of a head piece and one of several different types of hair pieces, with the rest of the body usually built from basic System bricks.
These figures came before the minifigures. The first minifigure was released four years later in 600 Police Car in 1978. After their introduction, minifigures were used together with Homemaker figures to represent a baby or a doll.
- Some hair parts (man, woman) can be assembled in two configurations because they have two front sides, enabling to change the hair dressing with the same part (turning it). This allows, with the same part, to have both the boy and the man hair dressing, or the girl and woman hair parts. Two examples are given below:
- The arms could be made of several lengths (1 or two) because they are made of several parts. This helps to recognize adults (double length) from kids (single length).
- The arm parts have been used later for other purposes, like for the arms of 6880 Surface Explorer or the 6822 Space Shuttle. In this new usage the arms have been replaced with grippers, for instance. The colors have moved from vivid colours (blue, yellow, red) for clothes to technical colours (grey, white) for arms and technical systems.
- The head has three attachments, two on the side (ears) one on the top. Hair pieces are fixed on the two hears, hats on the top.

Yes, there is a slight difference (although it appears there's no complete consensus on this).
A classifier, in linguistics (not just in Mandarin), is a word or morpheme used to express that a countable noun belongs to a semantic class. Here "semantic class" means a category of referents with some common traits; if we think about how classifiers work in Chinese, this is easy to understand.
For example, the classifier 条 is used for long, narrow and flexible objects. So when we say:
we are implying that the fish belongs to a class of things that, more or less, share the same properties: long, narrow and flexible. That is the semantic class, and that's why the classifier is called classifier.
Therefore, by using a different classifier, we offer a different classification of that object. When we say:
we are conveying that fish belongs to the category, or class, of things that go in "groups" (in "schools" actually!!!).
Now, English does have measure words: these are mostly nouns with their own meaning that work as units of measurement for mass nouns, which are not countable. They come in the form
a something of . Let's consider the word water. In English we can't count it ("one water", "two waters"). So when we need to quantify a certain amount of water, we have to use a word that describes a precise unit of measurement, for example:
a drop of water
a liter of water
an ocean of water
This definition of measure words works in Chinese too. The difference being that in Chinese there are classifiers proper and measure words. So what's actually the difference?
Classifiers are not standalone words, they don't have meaning on their own; and as in English, they still can't accompany mass nouns (consider 两个水 vs 两升水)
Measure words are words with a precise meaning, which can also work as units of measurement; and they can accompany mass nouns.
Her and Hsieh, On the Semantic Distinction between Classifiers and
Measure Words in Chinese propose also the following definitions, based on tests to appraise whether a certain counter word is a classifier or a measure word:
Classifiers classify or categorize nouns by highlighting some salient or inherent properties of the noun and thus contribute no additional meaning.
Measure words, on the other hand, play a substantive role in denoting the quantity of the entity named by the noun.
So, saying 一条鱼 does not add new information to what we already know about a fish. A fish is inherently a long and flexible object (mostly; an inflated puffer fish maybe is not "long"). Hence, 条 is a classifier proper. Whereas saying 一箱鱼 does add new information, we are saying that the fish comes in crates, where fish, in itself, doesn't inherently come in crates. Hence, in this example 箱 is a measure word.
In conclusion, classifiers proper stress the existence of an essential feature of the counted noun, whereas measure words stress a transient, not inherent (accidental) numerical feature.


Twilio on Rails
By Chris Rittersdorf on 20 Jan 2012
The use of smart phones is on the rise, however SMS text messaging is still the best way to reach the broadest customer base, especially in developing countries. If you have a Ruby on Rails application that needs to reach this broad customer base, Twilio is an excellent tool to have in your toolbox.
It's easy to add Twilio to a Rails application. This post will walk you through the process of integrating Rails with Twilio, including:
 - Signing Up for a Twilio Account
 - Testing with Twilio's Sandbox App
 - Integrating Twilio with a Rails Application
 - Configuring your Twilio enabled Rails application for Production
Let's get started!
Signing Up for Twilio
Signing up for Twilio is as simple as providing your name, email and password. After you sign up and log in for the first time, you are taken to the Dashboard. This will give you plenty of information to get started. Upon signing up, you are given $30 in credits to get started. These credits are spent every time a text message is sent or received by Twilio.
Twilio Dashboard
In the bottom left section of your dashboard, you'll see a box called Sandbox App. The Twilio Sandbox is where you want to do development work with Twilio. The Sandbox not only lets you test out your SMS enabled application without burning through credits, but it also lets you lock down which mobile phones can send text messages to it and which mobile phones it can send text messages to. This is in contrast to the live account which consumes credits, and can send and receive text messages to and from any mobile phone. Now that you know what the Sandbox is, let's try it out.
Testing Your Account Using the Sandbox
To test the SMS sandbox, send a text message from your phone to the sandbox number. The content doesn't matter, it can be anything. Try texting "hello twilio". You'll then see a reply similar to this:
Sent from the Twilio Sandbox Number - Error: No PIN. Make sure you begin your message with the Sandbox PIN from your Twilio Dashboard.
Any time you interact with the Twilio Sandbox, you must provide a PIN along with all communications (whether SMS or Voice). This PIN is located below the Sandbox number on your dashboard. Enter the pin at the beginning of your text message, for example:
28910293 hello twilio
You'll then get a reply from the default Twilio Service located at:
Now that you've confirmed that your account is in working order, let's see how was can leverage service in a Ruby on Rails application.
Integrating Twilio with Your Rails Application
Web applications communicate with Twilio using an XML variant called TwiML. For example:
This section of TwiML describes how to respond to a user calling a phone number. It speaks a message during the phone call, then sends the user an SMS message. But, it's no fun writing TwiML. And since we're using Ruby, there's a gem for that! The twiliio-ruby gem abstracts TwiML into an easy to use Ruby API.
In your Rails application, simply add the twilio-ruby gem to your Gemfile:
Now you have the necessary library to start sending text messages. So now let's use it!
Sending a Text Message Using Twilio
Sending a text message with your Rails application is simple. But before doing so, there is one configuration we have to make. To test your application using the Twilio Sandbox, you'll need to white-list any phone numbers you plan to send SMS messages to. You can do this by going to the Numbers tab and clicking the Verify Number button. There is a series of steps you'll have to complete to verify your number.
Verify Phone Number
After you've verified the phone number, your application can now send text messages. The following code example show you how:
In this example, the send_text_message action receives a phone number from a form post, then relays a hard-coded message to that phone number via SMS. The twilio_sid, twilio_token, and twilio_phone_number variables contain the configuration information for authentication using the twilio-ruby gem. Generally, you'd want to pull this into a configuration file that gets loaded when your application loads, but I've put them into local variables for simplicity.
Receiving a Text Message Using Twilio
In order to receive a text message from a mobile device, you'll have to expose an endpoint that is reachable by Twilio. Here is an example:
In this example, the index action receives a POST from Twilio. It grabs the message body, and the phone number of the sender and logs it. Retrieving the information from the Twilio POST is as simple as looking at the params hash:
In order for text messages to reach your application you have to tell Twilio where to send requests. This is again done in the Sandbox App section of the Twilio Dashboard. Specify your publicly facing endpoint in the SMS URL field and click "Save".
If you're running your server locally and have no publicly facing endpoint, you can use a service like tunnlr to create one. This creates a publicly accessible URL with an SSH tunnel back to your local machine.
So the publicly facing endpoint for your application would look something like:
Configuring Twilio for Production
To deploy your SMS enabled application in a production environment, there are three things you'll need to do: buy a Twilio phone number, configure that phone number in your application, and then configure the production end-point in Twilio.
Purchasing a phone number requires you to enter payment information and decide on a phone number to provision. Twilio will guide you through the process. At the time of writing, Twilio's pricing is set at $1.00 a month plus an additional 1¢ charge per text.
Also, you will need to update the Twilio phone number in your application to the new number that you've provisioned. The examples above contained a variable with the value for a Twilio phone number. Change this value to the new phone number you provisioned.
Finally, you'll now have to configure the SMS endpoint much like how we did for the Sandbox. Click on the "Numbers > Twilio Numbers" tab. Then click on the phone number you provisioned. Finally, in the "SMS Request URL" field, specify your publicly facing production endpoint URL, then click "Save Changes".
Whether it be for those on-the-go, or those who otherwise are not able to use a computer or smart phone, SMS provides excellent alternative interface for the users of your web application. For those looking for a simple and affordable way to get started, Twilio is an outstanding option. So now that you know how to get started, what will you build using Twilio?

Porcelain KVP plate from 1955.
The Kasernierte Volkspolizei (German for Barracked People's Police) was the precursor to the National People's Army (NVA) in East Germany. Their original headquarters was in Adlershof locality in Berlin, and from 1954 in Strausberg in modern-day Brandenburg. They ceased to exist after 1956, having been transformed into the NVA.
In October 1948 the Soviet Military Administration in Germany formed the Alert Police (Bereitschaftspolizei), a force of armed units housed in barracks and trained in military fashion. The force consisted of forty units with 100–250 men each, the units being subordinated to provincial authorities. Many of the officers and men were recruited from among German POWs held in the Soviet Union.
