Warm Dark Matter
Warm dark matter (WDM) is a hypothesized form of dark matter that has properties intermediate between those of hot dark matter and cold dark matter, causing structure formation to occur bottom-up from above their free-streaming scale, and top-down below their free streaming scale. The most common WDM candidates are sterile neutrinos and gravitinos. The WIMPs (weakly interacting massive particles), when produced non-thermally, could be candidates for warm dark matter. In general, however, the thermally produced WIMPs are cold dark matter candidates. keVins and GeVins One possible WDM candidate particle with a mass of a few keV comes from introducing two new, zero charge, zero lepton number fermions to the Standard Model of Particle Physics: "keV-mass inert fermions" (keVins) and "GeV-mass inert fermions" (GeVins). keVins are overproduced if they reach thermal equilibrium in the early universe, but in some scenarios the entropy production from the decays of unstable heavier particles ...

Warm Dense Matter
Warm dense matter, abbreviated WDM, can refer to either equilibrium or non-equilibrium states of matter in a (loosely defined) regime of temperature and density between condensed matter and hot plasma. It can be defined as the state that is too dense to be described by weakly coupled plasma physics yet too hot to be described by condensed matter physics. In this state, the potential energy of the Coulomb interaction between electrons and ions is on the same order of magnitude (or even significantly exceeds) their thermal energy, while the latter is comparable to the Fermi energy. Typically, WDM has a density somewhere between and a temperature on the order of several thousand kelvins (somewhere between , in the units favored by practitioners). WDM is expected in the interiors of giant planets, brown dwarf Brown dwarfs (also called failed stars) are substellar objects that are not massive enough to sustain nuclear fusion of ordinary hydrogen ( 1H) into helium in their ...

Wavelength-division Multiplexing
In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. This technique enables bidirectional communications over a single strand of fiber, also called wavelength-division duplexing, as well as multiplication of capacity. The term WDM is commonly applied to an optical carrier, which is typically described by its wavelength, whereas frequency-division multiplexing typically applies to a radio carrier which is more often described by frequency. This is purely conventional because wavelength and frequency communicate the same information. Specifically, frequency (in Hertz, which is cycles per second) multiplied by wavelength (the physical length of one cycle) equals the velocity of the carrier wave. In a vacuum, this is the speed of light, usually denoted by the lowercase letter, c. In glass fiber, it is subst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wax Deposition Modeling
Waxes are a diverse class of organic compounds that are lipophilic, malleable solids near ambient temperatures. They include higher alkanes and lipids, typically with melting points above about 40 °C (104 °F), melting to give low viscosity liquids. Waxes are insoluble in water but soluble in nonpolar organic solvents such as hexane, benzene and chloroform. Natural waxes of different types are produced by plants and animals and occur in petroleum. Chemistry Waxes are organic compounds that characteristically consist of long aliphatic alkyl chains, although aromatic compounds may also be present. Natural waxes may contain unsaturated bonds and include various functional groups such as fatty acids, primary and secondary alcohols, ketones, aldehydes and fatty acid esters. Synthetic waxes often consist of homologous series of long-chain aliphatic hydrocarbons (alkanes or paraffins) that lack functional groups. Plant and animal waxes Waxes are synthesized ...

3d Printing
3D printing or additive manufacturing is the Manufacturing, construction of a three-dimensional object from a computer-aided design, CAD model or a digital 3D modeling, 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under Computer Numerical Control, computer control, with material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer. In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. , the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology, whereby the term ''additive manufacturing'' can be used synonymously with ''3D printing''. One of the key advantages of 3D printing is the ability to produce very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Windows Driver Model
In computing, the Windows Driver Model (WDM) also known at one point as the Win32 Driver Model is a framework for device drivers that was introduced with Windows 98 and Windows 2000 to replace VxD, which was used on older versions of Windows such as Windows 95 and Windows 3.1, as well as the Windows NT Driver Model. Overview WDM drivers are layered in a stack and communicate with each other via I/O request packets (IRPs). The Microsoft Windows Driver Model unified driver models for the Windows 9x and Windows NT product lines by standardizing requirements and reducing the amount of code that needed to be written. WDM drivers will not run on operating systems earlier than Windows 98 or Windows 2000, such as Windows 95 (before the OSR2 update that sideloads the WDM model), Windows NT 4.0 and Windows 3.1. By conforming to WDM, drivers can be binary compatible and source-compatible across Windows 98, Windows 98 Second Edition, Windows Me, Windows 2000, Windows XP, Windows Server 2003 an ...

Locomotives Of India
The Indian Railways primarily operates fleet of electric and diesel locomotives, along with several compressed natural gas (CNG) locomotives. Steam locomotives are operated on a few World Heritage Sites and also run occasionally as heritage trains. A locomotive is also known as a loco or more popularly as an engine. The country's first steam locomotive ran on the Red Hill Railway (built by Arthur Cotton to transport granite for road-building) from Red Hills to the Chintadripet bridge in Madras in 1837. Classification Locomotives were classified by track gauge, motive power, function and power (or model number) in a four- or five-letter code. The first letter denotes the track gauge. The second letter denotes motive power (diesel or electric), and the third letter denotes use (goods, passenger, mixed or shunting). The fourth letter denotes a locomotive's chronological model number. In 2002, a new classification system was adopted. For newer diesel locomotives, the four ...

Western Development Museum
The Western Development Museum is a network of four museums in Saskatchewan, Canada preserving and recording the social and economic development of the province. The museum has branches in Moose Jaw, North Battleford, Saskatoon and Yorkton. Respectively, each branch focuses on a different theme: transportation, agriculture, economy, and people. The museum is affiliated with the Canadian Museums Association, the Canadian Heritage Information Network, and Virtual Museum of Canada. History Originally started as a grass-roots movement, the museum was founded with the passage of the Western Development Museum Act in 1949. The first home for the museum in 1949 was a refurbished hangar in North Battleford. Later the same year a similar structure in Saskatoon was converted into a second location for the museum. A third hangar was procured in Yorkton in 1951 and was likewise converted. In 1972, the first purpose-built buildings were constructed to house new locations for the museums in York ...

Waking Down In Mutuality
Waking Down in Mutuality (also known as WDM, Waking Down) and Trillium Awakening, are a set of spiritual teachings and a community that seek to support the integration of spiritual awakening into ordinary human life. Waking Down and Waking Down in Mutuality are registered trademarks of Saniel Bonder and Linda Groves-Bonder. The teachings are also offered through the Trillium Awakening Teachers Circle (formerly known as the Waking Down Teachers Association), a non-profit association of autonomous teachers. Waking Down was founded by Saniel Bonder in the early 1990s after (and partially as a reaction to) 20 years of work with his former guru, Adi Da Samraj. While acknowledging the necessity for an organization to have some amount of hierarchy, and for a teaching organization to have a body of recognized teachers, WDM and Trillium Awakening describe their work as aspirant (or participant) centered rather than teacher, guru, or organization centered.
