International Alphabet Of Sanskrit Transliteration
The International Alphabet of Sanskrit Transliteration (IAST) is a transliteration scheme that allows the lossless romanisation of Indic scripts as employed by Sanskrit and related Indic languages. It is based on a scheme that emerged during the 19th century from suggestions by Charles Trevelyan, William Jones, Monier Monier-Williams and other scholars, and formalised by the Transliteration Committee of the Geneva Oriental Congress, in September 1894. IAST makes it possible for the reader to read the Indic text unambiguously, exactly as if it were in the original Indic script. It is this faithfulness to the original scripts that accounts for its continuing popularity amongst scholars. Usage Scholars commonly use IAST in publications that cite textual material in Sanskrit, Pāḷi and other classical Indian languages. IAST is also used for major e-text repositories such as SARIT, Muktabodha, GRETIL, and sanskritdocuments.org. The IAST scheme represents more than a centu ...

Indian Army
The Indian Army (IA) (ISO 15919, ISO: ) is the Land warfare, land-based branch and largest component of the Indian Armed Forces. The President of India is the Commander-in-Chief, Supreme Commander of the Indian Army, and its professional head is the Chief of the Army Staff (India), Chief of the Army Staff (COAS). The British Indian Army, Indian Army was established on 1 April 1895 alongside the long established presidency armies of the East India Company, which too were absorbed into it in 1903. Some princely states maintained their own armies which formed the Imperial Service Troops which, along with the Indian Army formed the land component of the Armed Forces of the Crown of India, responsible for the defence of the Indian Empire. The Imperial Service Troops were merged into the Indian Army after Independence of India, independence. The units and regiments of the Indian Army have diverse histories and have participated in several battles and campaigns around the world, earnin ...

Border Security Force
The Border Security Force (BSF) is a central armed police force in India under the Ministry of Home Affairs. It is responsible for guarding India’s borders with Pakistan and Bangladesh. It was formed in the wake of the Indo-Pak War of 1965 to ensure the security of India’s borders and for related matters. The BSF has grown from 25 battalions in 1965, to 193 battalions with a sanctioned strength of 270,000 personnel including an expanding air wing, water wing, an artillery regiment and specialised units. It is currently the world's largest border security force. BSF has been termed the ''First Line of Defence'' of Indian territories. History Since India's independence in 1947, the protection of its international boundaries was the responsibility of the local police in each border state, with little inter-state coordination. However, during the Indo-Pakistani War of 1965, Pakistan attacked Sardar Post, Char Bet, and Beria Bet on April 9, 1965, in Kutch. This attack ...

Thermography
Infrared thermography (IRT), thermal video or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 μm) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals becom ...

Night Vision
Night vision is the ability to see in low-light conditions, either naturally with scotopic vision or through a night-vision device. Night vision requires both sufficient spectral range and sufficient intensity range. Humans have poor night vision compared to many animals such as cats, dogs, foxes and rabbits, in part because the human eye lacks a tapetum lucidum, tissue behind the retina that reflects light back through the retina thus increasing the light available to the photoreceptors. Types of ranges Spectral range Night-useful spectral range techniques can sense radiation that is invisible to a human observer. Human vision is confined to a small portion of the electromagnetic spectrum called visible light. Enhanced spectral range allows the viewer to take advantage of non-visible sources of electromagnetic radiation (such as near-infrared or ultraviolet radiation). Some animals such as the mantis shrimp and trout can see using much more of the infrared and/or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrared Detector
An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic (photodetectors). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. Bolometers and microbolometers are based on changes in resistance. Thermocouples and thermopiles use the thermoelectric effect. Golay cells follow thermal expansion. In IR spectrometers the pyroelectric detectors are the most widespread. The response time and sensitivity of photonic detectors can be much higher, but usually these have to be cooled to cut thermal noise. The materials in these are semiconductors with narrow band gaps. Incident IR photons can cause electronic excitations. In photoconductive detectors, the resistivity of the detector element is monitored. Photovoltaic detectors contain a p-n junction on which photoelectric current appears upon illumination. An infrared detector is hybridized by connecting ...

Military Radars Of India
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. Beyond warfare, the military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control, promotion of political agendas, emergency services and reconstruction, prot ...
