In Mathematica, the only structure that exists is the tree, which is populated by symbols. In the Haskell syntax used thus far, this could be defined as data SymbolTree = Symbol String [Symbol] An example tree could then look like Symbol "a" [Symbol "b" [], Symbol "c" []] In the traditional, more suitable syntax, the symbols are written as they are and the levels of the tree are represented using [], so that for instance a[b,c] is a tree with a as the parent, and b and c as the children. A pattern in Mathematica involves putting "_" at ...

Whether Visual Basic .NET should be considered as just another version of Visual Basic or a completely different language is a topic of debate. This is not obvious, as once the methods that have been moved around and which can be automatically converted are accounted for, the basic syntax of the language has not seen many "breaking" changes, just additions to support new features like structured exception handling and short circuited expressions. One simple change that can be confusing to previous users is that of Integer and Long data types ...

In the United States, crosswalks are usually marked with white stripes, though every municipality seems to have a slightly different method, style, or pattern for doing so (and the styles vary over time as intersections are built and replaced). There are two main methods for road markings in the United States. Most frequently, they are marked with two thick white lines running from one side of the road to the other. A shorter third line is usually also present, to be used as a stop point for vehicles and discourage drivers from pulling into the crosswalk. The more easily visible zebra stripes (like UK zebra cross ...

A cravat is the neckband that was the forerunner of the modern tailored necktie. From the end of the 16th century, the term "band" applied to any long strip of cloth worn round the neck that was not a "ruff". The ruff itself had started its career in the earlier 16th century as a starched and pleated strip of white linen that could be freshly changed to keep the neck of a doublet from getting increasingly grimy, or for use as a bib or napkin. A "band" could indicate a plain, attached shirt collar or a detached "falling band" th ...

The structure of a lex file is intentionally similar to that of a yacc file; files are divided up into three parts: a definition section, a rules section, and a C code section. Sections are separated by lines that contain only two percent signs: %%. The definition section is the place to define macros using regular expressions, and also to import header files written in C. The rules section is the most important section; it associates rules to C statements. When lex sees a pattern in its input matching a gi ...

When some person is recognized, they are accorded some special status, such as a name, title, or classification. Recognition can take many forms, such as mention in the mass media. Recognition - Acculturation. It becomes easier for persons to become accepted into some social process if they allow themselves to fit into a social identity, as a signal that they implicity accept some social norm. Thus the use of uniform dress is a signal for both group inclusion and acceptance. Gangs use signals and dress for this purpose. Dress co ...

The name "SOAP" was originally an acronym for Simple Object Access Protocol, but the full name was dropped in Version 1.2 of the SOAP specification, because the focus of SOAP shifted from object access to object inter-operability. Originally designed by Dave Winer, Don Box, Bob Atkinson, and Mohsen Al-Ghosein in 1998 with backing from Microsoft (where Atkinson and Al-Ghosein worked at the time), the SOAP specification is currently maintained by the XML Protocol Working Group of the World Wide Web Consortium.

Autostereogram - Simple wallpaper autostereogram. The human brain accomplishes stereo vision by a complex set of mechanisms which attempt to relate the two slightly different two-dimensional images seen by the two eyes. The brain tries to assemble a three-dimensional impression by matching each point (or set of points) in one eye's view with the equivalent point (or set of points) in the other eye's view. It therefore assesses the points' positi ...

Artificial neural network - Feedforward neural network. The feedforward neural networks are the first and arguably simplest type of artificial neural networks devised. In this network, the information moves in only one direction, forward, from the input nodes, through the hidden nodes (if any) and to the output nodes. There are no cycles or loops in the network. The earliest kind of neural network is a single-layer perceptron network, which consists of a single layer of output nodes; the inp ...

Hermann von Helmholtz formulated mathematical equations for X-rays. Physicist Johann Hittorf observed tubes with energy rays extending from a negative electrode. William Crookes investigated the effects of energy discharges on rare gases. Heinrich Hertz began experimenting and demonstrated that cathode rays could penetrate very thin metal foil (such as aluminium). In 1887, Nikola Tesla began to investigate X-rays and produced the bremsstrahlung process. In 1895, Wilhelm Röntgen began observing and further documenting X-ra ...

At the close of the 19th century, the case for atomic theory, that matter was made of particulate objects or atoms, was well established. Electricity, first thought to be a fluid, was understood to consist of particles called electrons, as demonstrated by J.J. Thompson in his experiments with cathode rays. In brief, it was understood that much of nature was made of particles. At the same time, waves were well understood, together with wave phenomena such as diffraction and interference. Light was believed to be a wave, as Thomas Young's double-slit experiment and effects such as Fraunhofer diffraction had cl ...

The Temple of Peace was opened on 23 November 1938. It was a gift from Lord David Davies of Llandinam (Montgomeryshire) to the Welsh people. He wanted it to be "a memorial to those gallant men [and women] from all nations who gave their lives in the war that was to end war" and so it was dedicated to the memory of the loss of life as a result of the First World War (1914-1918). He had fought in the trenches during this war, and was actively involved in the search for stable international order through the League of Nations and the League of ...

Aesthetics - Visual arts. The field of aesthetics has enjoyed a rebirth in recent years. Modern art, particularly post-WWII up through the 1980s, in fact strongly reacted against notions of beauty. Some theorists (Hal Foster) have described this as an "anti-aesthetic." As media such as painting were deconstructed and explored to their very foundational or essential elements, creating an aesthetically beautiful work was no longer the key. Instead, artists focused on conceptual questions such as 'what is art?' or ' ...

Art stamps have become fashionable in the United States, more so than in Europe. While they are mostly regarded as children's toys in Europe, in the U.S. they are available in many intricate designs and are widely used to decorate various objects. Such art stamps can be used for easy decoration of useful things like paper for letters, greeting cards and similar things, but also can be combined with other techniques to create traditional art. ...

Information is any represented pattern. This view assumes neither accuracy nor directly communicating parties, but instead assumes a separation between an object and its representation, as well as the involvement of someone capable of understanding this relationship. This view seems therefore to require a conscious mind. Consider the following example: economic statistics represent an economy, however inaccurately. What are commonly referred to as data in computing, statistics, and other fields, are forms of information in this sense. The el ...

Mandrels are not recent inventions. Metal machining utilizing the spinning process has been recorded as far back as Egyptian hieroglyphic times. In metal spinning, a wood or metal spinning mandrel is used, the form of which corresponds with the internal contour of the part to be produced. This method securely clamps the raw material and allows for accurate machining into the desired final form. Since the material is clamped internally, there is no interference to the operator from the lathe/ ...

Analogy - Identity of relation. In ancient Greek the word αναλογια (analogia) originally meant proportionality, in the mathematical sense, and it was indeed sometimes translated to Latin as proportio. From there analogy was understood as identity of relation between any two ordered pairs, whether of mathematical nature or not. Kant's Critique of Judgment held to this notion. Kant argued that there can be exactly the same relation between two completely different objects. ...
