Sutlej River
The Sutlej River or the Satluj River is a major river in Asia, flowing through China, India and Pakistan, and is the longest of the five major rivers of the Punjab region. It is also known as ''Satadru''; and is the easternmost tributary of the Indus River. The combination of the Sutlej and Chenab rivers in the plains of Punjab forms the Panjnad, which finally flows into the Indus River at Mithankot. In India, the Bhakra Dam is built around the river Sutlej to provide irrigation and other facilities to the states of Punjab, Rajasthan and Haryana. The waters of the Sutlej are allocated to India under the Indus Waters Treaty between India and Pakistan, and are mostly diverted to irrigation canals in India like the Sirhind Canal, Bhakra Main Line and the Rajasthan canal. The mean annual flow is 14 million acre feet (MAF) (roughly 1.727 × 1013 L) upstream of Ropar barrage, downstream of the Bhakra dam. It has several major hydroelectric points, including the ...

Echo (phenomenon)
In audio signal processing and acoustics, an echo is a reflection of sound that arrives at the listener with a delay after the direct sound. The delay is directly proportional to the distance of the reflecting surface from the source and the listener. Typical examples are the echo produced by the bottom of a well, a building, or the walls of enclosed and empty rooms. Etymology The word ''echo'' derives from the Greek ἠχώ (''ēchō''), itself from ἦχος (''ēchos''), 'sound'. Echo in Greek mythology was a mountain nymph whose ability to speak was cursed, leaving her able only to repeat the last words spoken to her. Nature Some animals, such as cetaceans (dolphins and whales) and bats, use echo for location sensing and navigation, a process known as echolocation. Echoes are also the basis of sonar technology. Acoustic phenomenon Walls or other hard surfaces, such as mountains and privacy fences, reflect acoustic waves. The reason for reflection may be explained as a ...

Royal Indian Navy
The Royal Indian Navy (RIN) was the naval force of British Raj, British India and the Dominion of India. Along with the Presidency armies, later the British Indian Army, Indian Army, and from 1932 the Royal Indian Air Force, it was one of the Armed Forces of British India. From its origins in 1612 as the East India Company's Marine, the Navy underwent various changes, including changes to its name. Over time it was named the Bombay Marine (1686), the Bombay Marine Corps (1829), the Indian Navy (1830), Her Majesty's Indian Navy (1858), the Bombay and Bengal Marine (1863), the Indian Defence Force (1871), Her Majesty's Indian Marine (1877) and the Royal Indian Marine (1892).

Sloop-of-war
During the 18th and 19th centuries, a sloop-of-war was a warship of the Royal Navy with a single gun deck that carried up to 18 guns. The rating system of the Royal Navy covered all vessels with 20 or more guns; thus, the term encompassed all unrated warships, including List of gun-brigs of the Royal Navy, gun-brigs and Cutter (boat), cutters. In technical terms, even the more specialised bomb vessels and fire ships were classed by the Royal Navy as sloops-of-war, and in practice these were employed in the role of a sloop-of-war when not carrying out their specialised functions. In World War I and World War II, the Royal Navy reused the term "sloop" for specialised convoy-defence vessels, including the of the First World War and the highly successful of the Second World War, with anti-aircraft and anti-submarine capabilities. They performed similar duties to the destroyer escorts of the United States Navy, and also performed similar duties to the smaller corvettes of the Royal ...

Naval Base
A naval base, navy base, or military port is a military base, where warships and naval ships are docked when they have no mission at sea or need to restock. Ships may also undergo repairs. Some naval bases are temporary homes to aircraft that usually stay on ships but are undergoing maintenance while the ship is in port. In the United States, the United States Department of the Navy's General Order No. 135 issued in 1911 as a formal guide to naval terminology described a naval station as "any establishment for building, manufacturing, docking, repair, supply, or training under control of the Navy. It may also include several establishments". A naval base, by contrast, was "a point from which naval operations may be conducted". In most countries, naval bases are expressly named and identified as such. One peculiarity of the Royal Navy and certain other navies which closely follow British naval traditions is the concept of the stone frigate: a naval base on land that is named like ...

Karwar
Karwar is a coastal City and the administrative headquarters of Uttara Kannada district, formerly part of the Bombay Presidency, located at the mouth of the Kali River (Karnataka), Kali river along the Konkan Coast in the present-day state of Karnataka, India. Etymology Karwar, also known locally as "Kādwād", derived its name from the nearby village of "Kade-Wādā". In the local Konkani language, Konkani, ''Kade'' means "Last" and ''Wādā'' means "Ward". Hence, ''Kade-Wādā'' ("the last neighbourhood") referred to the southernmost Konkani-speaking village. During the British Raj, Crown rule in India, the name "Karwar" was spelt as "Carwar". The ancient name was "Baithkhol"—from an Arabic language, Arabic term ''Bait-e-kol''— meaning the "bay of safety". This is in the Indian history for maritime trade wherein black peppercorns, cardamom, and muslin cloth were exported from this Kādwād port and after the war with Veer Henja Naik (1803), the port activities were shif ...

ISO 9002
The ISO 9000 family is a set of international standards for quality management systems. It was developed in March 1987 by International Organization for Standardization. The goal of these standards is to help organizations ensure that they meet customer and other stakeholder needs within the statutory and regulatory requirements related to a product or service. The standards were designed to fit into an integrated management system. The ISO refers to the set of standards as a "family", bringing together the standard for quality management systems and a set of "supporting standards", and their presentation as a family facilitates their integrated application within an organisation. ISO 9000 deals with the fundamentals and vocabulary of QMS, including the seven quality management principles that underlie the family of standards. ISO 9001 deals with the requirements that organizations wishing to meet the standard must fulfill. A companion document, ISO/TS 9002, provides guidelines f ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances ( ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and sodar (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low ( infrasonic) to e ...
