  2. Upload components - Wikipedia

    en.wikipedia.org/wiki/Upload_components

    Multiple files and folder upload Some websites require support for uploading multiple files at once. This feature is extremely important for upload components on social networks, photo galleries, file sharing, etc. The standard HTML4 approach is cumbersome. Upload components support multiple file uploads in a more flexible fashion, for example ...

  3. Hydrogen-moderated self-regulating nuclear power module

    en.wikipedia.org/wiki/Hydrogen-moderated_self...

    According to the patent application [5] the reactor design has some notable characteristics, that sets it apart from other reactor designs. It uses uranium hydride (UH 3) "low-enriched" to 5% uranium-235—the remainder is uranium-238—as the nuclear fuel, rather than the usual metallic uranium or uranium dioxide that composes the fuel rods of contemporary light-water reactors.

    Physical security information management (PSIM) is a category of software that provides a platform and applications created by middleware developers, designed to integrate multiple unconnected security applications and devices and control them through one comprehensive user interface.

  5. Organic nuclear reactor - Wikipedia

    en.wikipedia.org/wiki/Organic_nuclear_reactor

    An organic nuclear reactor, or organic cooled reactor (OCR), is a type of nuclear reactor that uses some form of organic fluid, typically a hydrocarbon substance like polychlorinated biphenyl (PCB), for cooling and sometimes as a neutron moderator as well. Using an organic fluid had a major advantage over conventional designs using water as the ...

    M142 HIMARS launching a GMLRS rocket at the White Sands Missile Range in 2005. A multiple rocket launcher (MRL) or multiple launch rocket system (MLRS) is a type of rocket artillery system that contains multiple launchers which are fixed to a single platform, and shoots its rocket ordnance in a fashion similar to a volley gun.

  7. Traveling wave reactor - Wikipedia

    en.wikipedia.org/wiki/Traveling_wave_reactor

    After the reactor is started, four zones form within the core: the depleted zone, which contains mostly fission products and leftover fuel; the fission zone, where fission of bred fuel takes place; the breeding zone, where fissile material is created by neutron capture; and the fresh zone, which contains unreacted fertile material. The energy ...

    en.wikipedia.org/wiki/Multibody_system

    While single bodies or parts of a mechanical system are studied in detail with finite element methods, the behavior of the whole multibody system is usually studied with multibody system methods within the following areas: Aerospace engineering (helicopter, landing gears, behavior of machines under different gravity conditions) Biomechanics

  9. Atmospheric-pressure photoionization - Wikipedia

    en.wikipedia.org/wiki/Atmospheric-pressure_photo...

    The most common reaction is the abstraction of a hydrogen atom from the abundant solvent to form the stable [M+H] + cation, which is usually the observed ion. [ 6 ] In dopant-APPI (or photoionization-induced APCI), a quantity of photoionizable molecules (e.g., toluene or acetone) is introduced into the sample stream to create a source of charge ...
