Isis is a goddess from the polytheistic pantheon of Egypt.
Isis or ISIS may also refer to:
Isis (stylized as ISIS) was a Los Angeles-based post-metal band, founded in Boston, Massachusetts, with a career spanning from 1997 to 2010. They borrowed from and helped to evolve a sound pioneered by the likes of Neurosis and Godflesh, creating heavy music consisting of lengthy songs that focus on repetition and evolution of structure.
The band's last album, Wavering Radiant, was released on 5 May 2009. They disbanded in June 2010, just before the release of a split EP with the Melvins.
This is a list of the Goa'uld characters that appear in Stargate, Stargate SG-1, and Stargate Atlantis. In the Stargate fictional universe, the Goa'uld are a parasitic alien race that use other beings as hosts. Ra had stated in the original Stargate film that he had used humans exclusively as hosts for millennia, because Goa'uld technology can repair human bodies so easily that by inhabiting human forms they can be in effect ageless, though they can still be injured or killed. Most Goa'uld pose as gods in order to control slave armies, and are considered evil, egocentric megalomaniacs by those who do not worship them. The Goa'uld are extremely intelligent and have an aptitude for understanding, working with, and using technology that is superior to that of humans. They each have full access to their species' genetic memory from the moment of birth. As a result, no Goa'uld has to learn how to operate any technological device; they 'know' how to do so innately.
In telecommunications, the coverage of a radio station is the geographic area where the station can communicate. Broadcasters and telecommunications companies frequently produce coverage maps to indicate to users the station's intended service area. Coverage depends on several factors, such as orography (i.e. mountains) and buildings, technology, radio frequency and perhaps most importantly for two-way telecommunications the sensitivity and transmit efficiency of the consumer equipment. Some frequencies provide better regional coverage, while other frequencies penetrate better through obstacles, such as buildings in cities.
The ability of a mobile phone to connect to a base station depends on the strength of the signal. That may be boosted by higher power transmissions, better antennas, taller antenna masts or alternative solutions like in-building picocells. Normal Macro-Cell signals need to be boosted to pass through buildings, which is a particular problem designing networks for large metropolitan areas with modern skyscrapers, hence the current drive for small cells and micro and pico cells. Signals also do not travel deep underground, so specialized transmission solutions are used to deliver mobile phone coverage into areas such as underground parking garages and subway trains.
Shot peening is a cold working process used to produce a compressive residual stress layer and modify mechanical properties of metals and composites. It entails impacting a surface with shot (round metallic, glass, or ceramic particles) with force sufficient to create plastic deformation.
It is similar to sandblasting, except that it operates by the mechanism of plasticity rather than abrasion: each particle functions as a ball-peen hammer. In practice, this means that less material is removed by the process, and less dust created.
Peening a surface spreads it plastically, causing changes in the mechanical properties of the surface. Its main application is to avoid the propagation of microcracks from a surface. Such cracks do not propagate in a material that is under a compressive stress; shot peening can create such a stress in the surface.
Shot peening is often called for in aircraft repairs to relieve tensile stresses built up in the grinding process and replace them with beneficial compressive stresses. Depending on the part geometry, part material, shot material, shot quality, shot intensity, and shot coverage, shot peening can increase fatigue life up to 1000%.
Origins (1993) is a tribal-ambient album by the American artist Steve Roach. The album is based on the concept that the Earth holds memories of prehistoric human civilization.
The liner notes contain a poem by Roach's wife Linda Kohanov from which many of the track titles were derived.
