In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images . On a spectrum of computational cost and visual fidelity, ray tracing-based rendering techniques, such as ray casting, recursive ray tracing, distribution ray tracing, photon mapping ...
A copy of the code book had been captured from U-110 on 9 May 1941. A similar coding system was used for weather reports from U-boats, the Wetterkurzschlüssel, (Weather Short Code Book). A copy of this had been captured from U-559 on 29 or 30 October 1942.
The ray tracing algorithm solves the rendering problem in a different way. In each step, it finds all intersections of a ray with a set of relevant primitives of the scene. Both approaches have their own benefits and drawbacks. Rasterization can be performed using devices based on a stream computing model, one triangle at the time, and access ...
At issue is the Congressional Review Act (CRA), a fast-track legislative tool that allows lawmakers to nullify rules even after the executive branch has completed them. The CRA also bars agencies ...
Test firing at the United States Naval Surface Warfare Center Dahlgren Division in January 2008 [1] [clarification needed] A railgun or rail gun is a linear motor device, typically designed as a weapon, that uses electromagnetic force to launch high- velocity projectiles. The projectile normally does not contain explosives, instead relying on ...

The Diagnostic Trouble Codes (DTC's) of OBD-I vehicles can usually be found without an expensive scan tool. Each manufacturer used their own Diagnostic Link Connector (DLC), DLC location, DTC definitions, and procedure to read the DTC's from the vehicle.
US stocks closed lower Thursday after the latest GDP report showed that US economic growth slowed to 1.6% in the first quarter of the year, a much weaker pace than expected.
The High-frequency Active Auroral Research Program ( HAARP) is a University of Alaska Fairbanks program which researches the ionosphere – the highest, ionized part of Earth's atmosphere . The most prominent instrument at HAARP is the Ionospheric Research Instrument (IRI), a high-power radio frequency transmitter facility operating in the high ...
A radioactive tracer can also be used to track the distribution of a substance within a natural system such as a cell or tissue, [1] or as a flow tracer to track fluid flow. Radioactive tracers are also used to determine the location of fractures created by hydraulic fracturing in natural gas production. [2] Radioactive tracers form the basis ...
In computing, telecommunication, information theory, and coding theory, forward error correction ( FEC) or channel coding [1] [2] [3] is a technique used for controlling errors in data transmission over unreliable or noisy communication channels .
