The Hydrologic Evaluation of Landfill Performance (HELP) model is a quasi-two-dimensional hydrologic numerical model for conducting water balance analysis of landfills, cover systems, and other solid waste containment facilities; it was developed for the United States Environmental Protection Agency.
The ITU terrain loss model is a radio propagation model that provides a method to predict the median path loss for a telecommunication link. Developed on the basis of diffraction theory, this model predicts the path loss as a function of the height of path blockage and the First Fresnel zone for the transmission link.
Mountain/Cold Weather Boots, later renamed Rugged All Terrain (RAT) Boots, [25] and Extreme Cold Vapor Barrier Boots are given. The overboots are insulated with an air barrier, and include a valve to allow paratroopers to jump with them, while the RAT Boot is reinforced with chemically impregnated leather for durability and stability.
SPLAT! can use the Longley-Rice path loss and coverage prediction using the Irregular Terrain Model to predict the behaviour and reliability of radio links, and to predict path loss. SRTM filenames refer to the latitude and longitude of the southwest corner of the topographic dataset contained within the file.
Longley-Rice is also known as the irregular terrain model (ITM). It was created by scientists Anita Longley and Phil Rice of the Institute for Telecommunication Sciences (then part of the Environmental Science Services Administration) [ 2 ] in Boulder, Colorado for the needs of frequency planning in television broadcasting in the United States ...
DTED supports many applications, including line-of-sight analyses, terrain profiling, 3-D terrain visualization, mission planning/rehearsal, and modeling and simulation. DTED is a standard National Geospatial-Intelligence Agency (NGA) product that provides medium resolution, quantitative data in a digital format for military system applications ...
Racing Champions subsequently made a decision to sell off the model kit brands succeeded from the Ertl, including AMT. After the establishment of Round 2, Thomas Lowe showed an interest in purchasing AMT. In 2008, Lowe signed an agreement to produce and market AMT brand under Round 2. AMT brand and toolings were purchased outright by Round 2 in ...
Warwick produces its instruments and amplifiers using carbon-neutral principles. Any other manufacturing process is carbon-neutral as well. [1] [2] [3] The company is purchasing its wood from sustainable sources (certified by the Forest Stewardship Council) [4] and produces all the electricity it needs through its own natural-gas-powered plant, solar roof-mounted facilities, a boiler fueled by ...
