Spread (intuitionism)
In intuitionistic mathematics, a ''species'' is a collection (similar to a classical set in that a species is determined by its members). A spread is a particular kind of species of infinite sequences defined via finite decidable properties. In modern terminology, a spread is an inhabited closed set of sequences. The notion of spread was first proposed by L. E. J. Brouwer (1918B), and was used to define the real numbers (also called the continuum). As Brouwer's ideas were developed, the use of spreads became common in intuitionistic mathematics, especially when dealing with choice sequences and the foundations of intuitionistic analysis (Dummett 77, Troelstra 77). Simple examples of spreads are: *the set of sequences of even numbers; *the set of sequences of the integers 1–6; *the set of sequences of valid terminal commands. Spreads are defined via a ''spread function'', which performs a ( decidable) "check" on finite sequences. The notion of a spread and its spr ...

Spreading (debate)
Spreading is the act of speaking extremely fast during a competitive debating event, with the intent that one's opponent will be penalized for failing to respond to all arguments raised. It is a portmanteau of "speed" and "reading". The tactic relies on the fact that "failing to answer all opposing arguments" is an easy criterion for judges to award a win on, and that speaking fast and fielding an overwhelming number of distinct arguments can be a viable strategy. Spreading dominated the US school debate circuit in the 1990s. In the early 2000s, the style itself became a topic of many debates, with some arguing that it was exclusionary and possibly discriminatory, as it focused on speaking fast rather than being impassioned about a subject, and some educational companies began selling debate prep materials to assist those employing the style in packing as many topics as possible into their arguments, creating an advantage for those with more money. The public forum debate format w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarot
The tarot (, first known as '' trionfi'' and later as ''tarocchi'' or ''tarocks'') is a pack of playing cards, used from at least the mid-15th century in various parts of Europe to play card games such as Tarocchini. From their Italian roots, tarot playing cards spread to most of Europe evolving into a family of games that includes German Grosstarok and more recent games such as French Tarot and Austrian Königrufen which are still played today. In the late 18th century, French occultists began to make elaborate, but unsubstantiated, claims about their history and meaning, leading to the emergence of custom decks for use in divination via tarot card reading and cartomancy. Thus there are two distinct types of tarot pack: those used for playing games and those used for divination. However, some older patterns, such as the Tarot de Marseille, originally intended for playing card games, have also been used for cartomancy. Like the common playing cards, tarot has four su ...

Bedspread
Bedding, also known as bedclothes or bed linen, is the materials laid above the mattress of a bed for hygiene, warmth, protection of the mattress, and decorative effect. Bedding is the removable and washable portion of a human sleeping environment. Multiple sets of bedding for each bed are often washed in rotation and/or changed seasonally to improve sleep comfort at varying room temperatures. Most standardized measurements for bedding are rectangular, but there are also some square-shaped sizes, which allows the user to put on bedding without having to consider its lengthwise orientation (e.g. a duvet). In American English, the word ''bedding'' generally does not include the mattress, bed frame, or bed base (such as box-spring), while in British English it does. In Australian and New Zealand English, bedding is often called ''manchester'', especially in shops. Manchester was a center of the cotton industry in the late 18th and the 19th century, and into the 20th century, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spread (food)
A spread is a food that is spread, generally with a knife, onto foods such as bread and crackers. Spreads are added to food to enhance the flavor or texture of the food, which may be considered bland without it. Butter and soft cheeses are typical spreads. A sandwich spread is a spreadable condiment used in a sandwich, in addition to more solid ingredients. Butter, mayonnaise, prepared mustard, and ketchup are typical sandwich spreads, along with their variants such as Thousand Island dressing, Tartar sauce, and Russian dressing. Spreads are different from dips, such as salsa, which are generally not applied to spread onto food, but have food dipped into them, instead. Common spreads include dairy spreads (such as cheeses, creams, and butters, although the term "butter" is broadly applied to many spreads), margarines, honey, plant-derived spreads (such as jams, jellies, and hummus), yeast spreads (such as vegemite and marmite), and meat-based spreads (such as '' pâ ...

Dew Point Depression
The dew point depression (T-Td) is the difference between the temperature and dew point temperature at a certain height in the atmosphere. For a constant temperature, the smaller the difference, the more moisture there is, and the higher the relative humidity. In the lower troposphere, more moisture (small dew point depression) results in lower cloud bases and lifted condensation levels (LCL). LCL height is an important factor modulating severe thunderstorms. One example concerns tornadogenesis, with tornadoes most likely if the dew point depression is 20 °F (11 °C) or less, and the likelihood of large, intense tornadoes increasing as dew point depression decreases. LCL height also factors in downburst and microburst activity. Conversely, instability is increased when there is a mid-level dry layer (large dew point depression) known as a " dry punch", which is favorable for convection if the lower layer is buoyant. As it measures moisture content in the atmosphere, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spreadsheet
A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form. Spreadsheets were developed as computerized analogs of paper accounting worksheets. The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. The term ''spreadsheet'' may also refer to one such electronic document. Spreadsheet users can adjust any stored value and observe the effects on calculated values. This makes the spreadsheet useful for "what-if" analysis since many cases can be rapidly investigated without manual recalculation. Modern spreadsheet software can have multiple interacting sheets and can display data either as text and numerals or in graphical form. Besides performing basic arithmetic and mathematical functions, modern spreadsheets provide built-in functions for common financial ...

Wetting
Wetting is the ability of a liquid to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together. This happens in presence of a gaseous phase or another liquid phase not miscible with the first one. The degree of wetting (wettability) is determined by a force balance between adhesive and cohesive forces. Wetting is important in the bonding or adherence of two materials. Wetting and the surface forces that control wetting are also responsible for other related effects, including capillary effects. There are two types of wetting: non-reactive wetting and reactive wetting. Wetting deals with three phases of matter: gas, liquid, and solid. It is now a center of attention in nanotechnology and nanoscience studies due to the advent of many nanomaterials in the past two decades (e.g. graphene, Carbon nano tube, carbon nanotube, boron nitride nanomesh).

Spread Toolkit
The Spread Toolkit is a computer software package that provides a high performance group communication system that is resilient to faults across local and wide area networks. Spread functions as a unified message bus for distributed applications, and provides highly tuned application-level multicast, group communication, and point to point support. Spread services range from reliable messaging to fully ordered messages with delivery guarantees. The toolkit consists of a messaging server, and client libraries for many software development environments, including C/C++ libraries (with and without thread support), a Java class to be used by applets or applications, and interfaces for Perl, Python, and Ruby. Interfaces for many other software environments have been provided by third parties. In typical operation, each computer in a cluster runs its own instance of the Spread server, and client applications connect locally to that server process. The Spread servers, in turn, co ...

Spread Spectrum
In telecommunication and radio communication, spread-spectrum techniques are methods by which a signal (e.g., an electrical, electromagnetic, or acoustic signal) generated with a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. These techniques are used for a variety of reasons, including the establishment of secure communications, increasing resistance to natural interference, noise, and jamming, to prevent detection, to limit power flux density (e.g., in satellite downlinks), and to enable multiple-access communications. Telecommunications Spread spectrum generally makes use of a sequential noise-like signal structure to spread the normally narrowband information signal over a relatively wideband (radio) band of frequencies. The receiver correlates the received signals to retrieve the original information signal. Originally there were two motivations: either to resist enemy efforts to jam the communica ...

Seafloor Spreading
Seafloor spreading or Seafloor spread is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. History of study Earlier theories by Alfred Wegener and Alexander du Toit of continental drift postulated that continents in motion "plowed" through the fixed and immovable seafloor. The idea that the seafloor itself moves and also carries the continents with it as it spreads from a central rift axis was proposed by Harold Hammond Hess from Princeton University and Robert Dietz of the U.S. Naval Electronics Laboratory in San Diego in the 1960s. The phenomenon is known today as plate tectonics. In locations where two plates move apart, at mid-ocean ridges, new seafloor is continually formed during seafloor spreading. Significance Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in ...
