Environmental Research Institute Of Michigan
The Environmental Research Institute of Michigan (ERIM) was a research institute at Ann Arbor, Michigan, founded in 1972. The institute contributed to the development of remote sensing, radar, and holography. ERIM grew out of a military and environmental research arm of the University of Michigan, the Michigan Aeronautical Research Center, later known as the Willow Run Research Center. A for-profit enterprise, ERIM International, split off from it in 1997. This was successively acquired by Veridian Corporation, by General Dynamics—moving to Ypsilanti, Michigan, Ypsilanti—and in 2014 by MacDonald, Dettwiler and Associates (MDA). Meanwhile, the remaining non-profit portion became the Altarum Institute in 2001. Part of Altarum was in 2006 merged into the Michigan Tech Research Institute (MTRI), conducting environmental and remote sensing research, while health systems research continues at Altarum Institute.

DHC-4 ERIM At Ramstein Air Base 1980
The de Havilland Canada DHC-4 Caribou (designated by the United States military as the CV-2 and later C-7 Caribou) is a Canadian specialized cargo aircraft with STOL, short takeoff and landing (STOL) capability. The Caribou was first flown in 1958 and although mainly retired from military operations, is still in use in small numbers as a rugged bush airplane. The design was further developed as the de Havilland Canada DHC-5 Buffalo, adding turboprop engines and other changes that further improved its short-field performance to the point where it competes with light aircraft even with a full load. Design and development The De Havilland Canada (DHC) company's third short takeoff and landing (STOL) design was a big increase in size compared to its earlier DHC Beaver and DHC Otter, and was the first DHC design powered by two engines. The Caribou was similar in concept in that it was designed as a rugged STOL utility aircraft. The Caribou was primarily a military tactical transp ...

Military Intelligence
Military intelligence is a military discipline that uses information collection and analysis List of intelligence gathering disciplines, approaches to provide guidance and direction to assist Commanding officer, commanders in decision making process, their decisions. This aim is achieved by providing an intelligence analysis, assessment of data from a range of sources, directed towards the commanders' mission requirements or responding to questions as part of operational or campaign planning. To provide an analysis, the commander's information requirements are first identified, which are then incorporated into intelligence collection, analysis, and dissemination. Areas of study may include the operational environment, hostile, friendly and neutral forces, the civilian population in an area of combat operations, and other broader areas of interest. Intelligence activities are conducted at all levels, from tactical to strategic, in peacetime, the period of transition to war, and d ...

Synthetic Aperture Radar
Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or 3D reconstruction, three-dimensional reconstructions of objects, such as landscapes. SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars. SAR is typically mounted on a moving platform, such as an aircraft or spacecraft, and has its origins in an advanced form of side looking airborne radar (SLAR). The distance the SAR device travels over a target during the period when the target scene is illuminated creates the large ''synthetic'' antenna aperture (the ''size'' of the antenna). Typically, the larger the aperture, the higher the image resolution will be, regardless of whether the aperture is physical (a large antenna) or synthetic (a moving antenna) – this allows SAR to create high-resolution images with comparatively small physical antennas. For a fixed antenna size and orientation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Information Technologies
Information technology (IT) is a set of related fields within information and communications technology (ICT), that encompass computer systems, software, programming languages, data and information processing, and storage. Information technology is an application of computer science and computer engineering. The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. Several products or services within an economy are associated with information technology, including computer hardware, software, electronics, semiconductors, internet, telecom equipment, and e-commerce.. An information technology system (IT system) is generally an information system, a communications system, or, more specifically speaking, a computer system — including all hardware, software, and peripheral equipment — operated by a limited group of IT users, and an IT project usually ...

Geospatial
Geographic data and information is defined in the ISO/TC 211 series of standards as data and information having an implicit or explicit association with a location relative to Earth (a geographic location or geographic position). It is also called geospatial data and information, georeferenced data and information, as well as geodata and geoinformation. Location information (known by the many names mentioned here) is stored in a geographic information system (GIS). There are also many different types of geodata, including vector graphics, vector files, raster graphics, raster files, geographic databases, web files, and multi-temporal data. Spatial data or spatial information is broader class of data whose geometry is relevant but it is not necessarily georeferenced, such as in computer-aided design (CAD), see geometric modeling. Fields of study Geographic data and information are the subject of a number of overlapping fields of study, mainly: * Geocomputation * Geographic info ...

Scientific
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into twoor threemajor branches: the natural sciences, which study the physical world, and the social sciences, which study individuals and societies. While referred to as the formal sciences, the study of logic, mathematics, and theoretical computer science are typically regarded as separate because they rely on deductive reasoning instead of the scientific method as their main methodology. Meanwhile, applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine. The history of science spans the majority of the historical record, with the earliest identifiable predecessors to modern science dating to the Bronze Age in Egypt and Mesopotamia (). Their contributions to mathematics, astronomy, and medicine entered and shaped the Greek natural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bering Glacier
Bering Glacier is a glacier in the U.S. state of Alaska. It currently terminates in Vitus Lake south of Alaska's Wrangell-St. Elias National Park, about from the Gulf of Alaska. Combined with the Bagley Icefield, where the snow that feeds the glacier accumulates, the Bering is the largest glacier in North America. The glacier is named after Vitus Bering. Glacier retreat and earthquakes Warmer temperatures and changes in precipitation over the past century have thinned the Bering Glacier by several thousand meters. Since 1900 the terminus has retreated as much as . The Bering Glacier exhibits "surges", acceleration events of the flow rate of the glacier, every 20 years or so. During these periods the glacier terminus advances. The surges are generally followed by periods of retreat, so despite the periodic advances the glacier has been shrinking overall. Most glaciers along the Alaskan coast have been retreating along with the Bering Glacier.''Bering Glacier: Interdisciplina ...

Vietnam War
The Vietnam War (1 November 1955 – 30 April 1975) was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam (Democratic Republic of Vietnam) and South Vietnam (Republic of Vietnam) and their allies. North Vietnam was supported by the Soviet Union and China, while South Vietnam was supported by the United States and other anti-communist nations. The conflict was the second of the Indochina wars and a proxy war of the Cold War between the Soviet Union and US. The Vietnam War was one of the postcolonial wars of national liberation, a theater in the Cold War, and a civil war, with civil warfare a defining feature from the outset. Direct United States in the Vietnam War, US military involvement escalated from 1965 until its withdrawal in 1973. The fighting spilled into the Laotian Civil War, Laotian and Cambodian Civil Wars, which ended with all three countries becoming Communism, communist in 1975. After the defeat of the French Union in the First Indoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiballistic Missile System
An anti-ballistic missile (ABM) is a surface-to-air missile designed to destroy in-flight ballistic missiles. They achieve this explosively (chemical or nuclear), or via hit-to-kill kinetic vehicles, which may also have self-maneuvering. Tactical systems are widely deployed to counter short and intermediate-range ballistic missiles that carry conventional warheads. Strategic systems, deployed by the United States, Russia, and Israel, are capable of intercepting intercontinental ballistic missiles, typically used to carry strategic nuclear warheads. During the Cold War, the 1972 ABM Treaty limited the nuclear arms race; excessive ICBM production would have been favoured to overwhelm ABM systems. Of the modern strategic ABM systems, only Russia's are themselves armed with nuclear warheads. Current counter-ICBM systems There are a limited number of systems worldwide that can intercept intercontinental ballistic missiles: * The Russian A-135 anti-ballistic missile system (up ...
