Rainwater Harvesting
Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation, so that it seeps down and restores the ground water. Dew and fog can also be collected with nets or other tools. Rainwater harvesting differs from stormwater harvesting as the runoff is typically collected from roofs and other surfaces for storage and subsequent reuse. Its uses include watering gardens, livestock, irrigation, domestic use with proper treatment, and domestic heating. The harvested water can also be committed to longer-term storage or groundwater recharge. Rainwater harvesting is one of the simplest and oldest methods of self-supply of water for households, having been used in South Asia and other countries for many thousands of years. Installations can be designed for different scales including household ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Random Walk Hypothesis
The random walk hypothesis is a financial theory stating that stock market prices evolve according to a random walk (so price changes are random) and thus cannot be predicted. History The concept can be traced to French broker Jules Regnault who published a book in 1863, and then to French mathematician Louis Bachelier whose Ph.D. dissertation titled "The Theory of Speculation" (1900) included some remarkable insights and commentary. The same ideas were later developed by MIT Sloan School of Management professor Paul Cootner in his 1964 book ''The Random Character of Stock Market Prices''. The term was popularized by the 1973 book ''A Random Walk Down Wall Street'' by Burton Malkiel, a professor of economics at Princeton University, and was used earlier in Eugene Fama's 1965 article "Random Walks In Stock Market Prices", which was a less technical version of his Ph.D. thesis. The theory that stock prices move randomly was earlier proposed by Maurice Kendall in his 1953 paper, '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Wine Headache
Red wine headache ("RWH") is a headache often accompanied by nausea and flushing that occurs after consuming red wine in susceptible individuals. White wine headaches have been less commonly reported. Sulfites Many wines contain a warning label about sulfites, and some people believe that sulfites are the cause of RWH and other allergic and pseudoallergic reactions. However, this may not be the case.K. MacNeil ''The Wine Bible'' pg 34 Workman Publishing 2001 Dried fruit and processed foods like lunch meat have more sulfites than red wine. Reactions to sulfites are not considered a "true allergy" and reactions more commonly occur in persons with asthma and may manifest themselves in difficulty breathing or skin reactions, rather than headache. Some wines may be exempt from including a sulfite warning. Wines that have under 10mg/L of sulfites do not need to be labeled that they contain sulfites. This includes added and natural sulfites, like sulfites that come from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revolutionary Workers Headquarters
Revolutionary Workers Headquarters (RWH) was a U.S. Marxist-Leninist organization that formed out of a split from the Revolutionary Communist Party (RCP) in 1977. After Mao Zedong, leader of the Communist Party of China, died in 1976, the majority of the RCP's leadership criticized the post-Mao Chinese leadership as "revisionist" and "capitalist-roaders", saying that China was no longer a socialist country. A sizable minority of the RCP believed China was still a socialist country, and continued to support the post-Mao Chinese Communist Party under new leader Hua Guofeng. They left the RCP to form the RWH. Aside from differences on how to assess the changes in China, the RWH also criticized the RCP for ultra-leftism, or left-idealism in their approach to political work in the U.S. After leaving the RCP, the RWH also did an extensive critique of the RCP's line on the national question, criticizing the RCP for being "white chauvinist". The RWH published this critique in a lengt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ridley–Watkins–Hilsum Theory
In solid state physics the Ridley–Watkins–Hilsum theory (RWH) explains the mechanism by which differential negative resistance is developed in a bulk solid state semiconductor material when a voltage is applied to the terminals of the sample. It is the theory behind the operation of the Gunn diode as well as several other microwave semiconductor devices, which are used practically in electronic oscillators to produce microwave power. It is named for British physicists Brian Ridley, Tom Watkins and Cyril Hilsum who wrote theoretical papers on the effect in 1961. Negative resistance oscillations in bulk semiconductors had been observed in the laboratory by J. B. Gunn in 1962, and were thus named the "Gunn effect", but physicist Herbert Kroemer pointed out in 1964 that Gunn's observations could be explained by the RWH theory. In essence, RWH mechanism is the transfer of conduction electrons in a semiconductor from a high mobility valley to lower-mobility, higher-energy satell ...

Book
A book is a medium for recording information in the form of writing or images, typically composed of many pages (made of papyrus, parchment, vellum, or paper) bound together and protected by a cover. The technical term for this physical arrangement is ''codex'' (plural, ''codices''). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its predecessor, the scroll. A single sheet in a codex is a leaf and each side of a leaf is a page. As an intellectual object, a book is prototypically a composition of such great length that it takes a considerable investment of time to compose and still considered as an investment of time to read. In a restricted sense, a book is a self-sufficient section or part of a longer composition, a usage reflecting that, in antiquity, long works had to be written on several scrolls and each scroll had to be identified by the book it contained. Each part of Aristotle's '' Physics'' is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haskell (programming Language)
Haskell () is a general-purpose, statically-typed, purely functional programming language with type inference and lazy evaluation. Designed for teaching, research and industrial applications, Haskell has pioneered a number of programming language features such as type classes, which enable type-safe operator overloading, and monadic IO. Haskell's main implementation is the Glasgow Haskell Compiler (GHC). It is named after logician Haskell Curry. Haskell's semantics are historically based on those of the Miranda programming language, which served to focus the efforts of the initial Haskell working group. The last formal specification of the language was made in July 2010, while the development of GHC continues to expand Haskell via language extensions. Haskell is used in academia and industry. , Haskell was the 28th most popular programming language by Google searches for tutorials, and made up less than 1% of active users on the GitHub source code repository.
