Impulse Response Function
In signal processing and control theory, the impulse response, or impulse response function (IRF), of a dynamic system is its output when presented with a brief input signal, called an impulse (). More generally, an impulse response is the reaction of any dynamic system in response to some external change. In both cases, the impulse response describes the reaction of the system as a function of time (or possibly as a function of some other independent variable that parameterizes the dynamic behavior of the system). In all these cases, the dynamic system and its impulse response may be actual physical objects, or may be mathematical systems of equations describing such objects. Since the impulse function contains all frequencies (see the Fourier transform of the Dirac delta function, showing infinite frequency bandwidth that the Dirac delta function has), the impulse response defines the response of a linear time-invariant system for all frequencies. Mathematical considerations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Initial Reaction Force
An initial reaction force (IRF), also known as an internal reaction force, or extreme reaction force (ERF) to inmates, is a type of small-scale riot squad in U.S. military prisons such as the Camp Delta detention center of Guantanamo Bay. A squad is suited up and ready to respond, at all times, in instances when one or more detainees are combative or resistive. Controversy It is alleged by detainees that the units also act as a punishment squad for detainees whose level of insubordination does not fit the criteria for IRF deployment. Part of the allegations charge that regular guards will create reasons to call on the IRF to brutalize detainees over petty or non-existent infractions; refusing to agree to the third cell search in a day or infractions as slight as placing their toiletries on their shelf in the wrong order. claims: "16. I have witnessed the activities of the Internal Reaction Force (hereinafter "IRF"), which consists of a squad of soldiers that enter a detainee's c ...

Immediate Response Force
The Immediate Response Force (IRF) is a rapid deployment force jointly maintained by the United States Army and United States Air Force, which is capable of deploying worldwide within 18 hours of notification. Background By 1980, the United States formed the Rapid Deployment Joint Task Force (RDJTF) as a rapid reaction force under the U.S. Readiness Command. Composed of contingently assigned units from the United States Army, United States Air Force, United States Navy, and United States Marine Corps, its mandate was to rapidly deploy to confront worldwide threats to American interests. With the passage of the 1986 Goldwater-Nichols Act, the relevance of a force with planet-wide responsibilities became less apparent and the RDJTF was deactivated. In the 2000s, the Global Response Force (GRF) was created as a pooled reserve of CONUS-based military assets that could be used to rapidly reinforce one of the Unified Combatant Commands in the event of an emergent threat to American int ...

Institute Of Space Physics (Sweden)
The Swedish Institute of Space Physics ( sv, Institutet för rymdfysik, IRF) is a Swedish government agency. The institute's primary task is to carry out basic research, education and associated observatory activities in space physics, space technology and atmospheric physics. Foundation The IRF was founded in 1957 and the first Kiruna-designed satellite experiment was launched in 1968. The institute has about one hundred employees and has its head office in Kiruna. Other offices are situated in Umeå, Uppsala and Lund. IRF, originally the Kiruna Geophysical Observatory, began as a department within the Royal Swedish Academy of Sciences. It has been a public research institute since 1973, under the auspices of the Swedish Ministry of Education and Culture. Satellite experiments IRF participates in several international satellite projects. At present, data from satellite instruments are being analysed to help us better comprehend the plasma-physical processes in the solar wind a ...

Interferon Regulatory Factor
Interferon regulatory factors (IRF) are proteins which regulate transcription of interferons (see regulation of gene expression). Interferon regulatory factors contain a conserved N-terminal region of about 120 amino acids, which folds into a structure that binds specifically to the IRF-element (IRF-E) motifs, which is located upstream of the interferon genes. Some viruses have evolved defense mechanisms that regulate and interfere with IRF functions to escape the host immune system. For instance, the remaining parts of the interferon regulatory factor sequence vary depending on the precise function of the protein. The Kaposi sarcoma herpesvirus, KSHV, is a cancer virus that encodes four different IRF-like genes; including vIRF1, which is a transforming oncoprotein that inhibits type 1 interferon activity. In addition, the expression of IRF genes is under epigenetic regulation by promoter DNA methylation. Role in IFN Signaling IRFs primarily regulate type I IFNs in the host ...

International Ranger Federation
The International Ranger Federation is an organisation which represents Park Rangers and Park Wardens across the world. Many countries have agencies that undertake the protection and management of natural areas. The rangers within these organisations are represented at the international level by the International Ranger Federation (IRF). The IRF seeks to represent Park Rangers on a professional level. A number of countries also have affiliated organisations with the same goals. Every 3 years the World Ranger Congress is held by a host country with the next one being in Chitwan, Nepal - 11 to 16 November 2019. History The International Ranger Federation (IRF) was founded in 1992 with a signed agreement between the Countryside Management Association (CMA), representing rangers in England and Wales; the Scottish Countryside Rangers Association The Scottish Countryside Rangers' Association (SCRA) is the professional association supporting rangers and other countryside professionals i ...
