INS ''Sagardhwani'' (A74) (Hindi : सागरध्वनि - ''Voice of the Sea'') is a marine Acoustics, acoustic Research vessel, research ship (MARS) owned by the Naval Physical and Oceanographic Laboratory (NPOL), a Defence Research and Development Organisation (DRDO) laboratory, and is maintained and operated by the Indian Navy, and based at Southern Naval Command, Kochi. The ship was built by Garden Reach Shipbuilders & Engineers, Kolkata, launched in May 1991, and commissioned in 1994. It is similar in design to the Sandhayak-class survey ships, ''Sandhayak''-class survey ships, but with the superstructure positioned amidships and a helipad forward. The vessel is designed to facilitate low noise and low vibration while carrying out acoustics, acoustic programmes. It has floating floors for scientific laboratories, anti-vibration mountings for machinery and equipment, balloon launching container and wind weather radar to carry out those experiments. It is also equipped ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Laboratory
A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratories are found in a variety of settings such as schools, universities, privately owned research institutions, corporate research and testing facilities, government regulatory and forensic investigation centers, physicians' offices, clinics, hospitals, regional and national referral centers, and even occasionally personal residences. Overview The organisation and contents of laboratories are determined by the differing requirements of the specialists working within. A physics laboratory might contain a particle accelerator or vacuum chamber, while a metallurgy laboratory could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's laboratory might be a room with one-way mirrors and hidden ...

Research Vessels Of India
Research is creative and systematic work undertaken to increase the stock of knowledge. It involves the collection, organization, and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion of past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economic, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Active Indian Navy Ships
The Indian Navy (IN), which is the naval warfare branch of the Indian Armed Forces, has approximately 135+ warships on active commission. By forethought, the IN's Maritime Capability Perspective Plan (MCPP) for the period 2012–2027 had set the objective of the service becoming a 200-ship fleet by 2035; however, that number has since been reduced to 175 in December 2019 – principally owing the IN's dearth of budgetary founding, its ageing fleet and delays in the construction of naval assets. By certain calculations, the IN is still estimated to comprise a future total of 155-160 ships by 2030. By inventory, the IN's principal assets include its Fleet carrier, aircraft carrier component – the service has operated a total of four aircraft carriers since 1961; its List of submarines of the Indian Navy, submarine component – which presently includes a Nuclear deterrence, strategic submarine force; and its Amphibious assault ship, amphibious component – which principally o ...

Acoustics
Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an Acoustical engineering, acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. Hearing (sense), Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound and hearing as a key element of mating rituals or for marking territories. Art, ...

Helipad
A helipad is the landing area of a heliport, in use by helicopters, powered lift, and vertical lift aircraft to land on surface. While helicopters and powered lift aircraft are able to operate on a variety of relatively flat surfaces, a fabricated helipad provides a clearly marked hard surface away from obstacles where such aircraft can land safely. Larger helipads, intended for use by helicopters and other vertical take-off and landing (VTOL) aircraft, may be called ''vertiports.'' An example is Vertiport Chicago, which opened in 2015. Usage Helipads may be located at a heliport or airport where fuel, air traffic control and service facilities for aircraft are available. Most helipads are located away from populated areas due to sounds, winds, space and cost constraints. Some skyscrapers have one on their roofs to accommodate air taxi services. Some basic helipads are built on top of highrise buildings for evacuation in case of a major fire outbreak. Major police de ...
