Telemetry

Telemetry (= remote sensing) is the transmission of measured values at a monitoring site located probe ( sensor ) to a remote location. At this place of receipt, the measured values are available only collected and recorded or evaluated immediately.

Telemetry is often accompanied by a pathway for detecting sensor, so as to respond to readings delivered with appropriate measures. This return path is called a remote control (Telekommandierung, Tele-Command).

Pure telemetry

A telemetry that transfers the data over long distances is called the far field telemetry. This is for example the
collection of weather data, technical data from a moving vehicle ( aircraft, space vehicles, racing cars), the tracking of migratory animals such as lynx and Honey Buzzard , in the transmission of decentralized traffic information or in the transmission of medical data inserted probes, where the outside world. is not felt.

Telemetry called applications in which data is transmitted over short distances by moving machine parts on a stationary receiver. For example, state data of gas turbine rotors and tire pressures of rotating vehicle wheels are provided.

Often the data to spatially widely separated locations are recorded and measured by telemetry to a central office sent there to be recorded and / or evaluated.

DEVELOPMENT OF SOCIOLOGY

Since the dawn of civilization, Society has been a subject for speculation
and inquiry along with other phenomena, which have agitated the restless
and inquisitive mind of man. Even centuries ago men were thinking about
society and its organisation and held views on man and his destiny, the rise
and fall of civilizations. Though they were thinking about the subject matter
of they were, called philosophers historians, thinkers, lawgivers and the like.
Thus, broadly it may be said that. Sociology has had a four fold origin, in
political philosophy, the philosophy of history, biological theories of evolution
and the movements for social and political reforms....... "
In India, the most ancient social thought can be seen in the Vedas, the
Puranas. the Upanishads. the laws of Manu and Arthashastra of Kautilya
which clearly reflect the social ideas of the Hindus.
In Ain-i-Akbari (or institutes (if Akbar) of Abul Fazai, one can see a
complete picture of society during the time of Akbar. the great Mughul. All
these works show that the subject of sociology is an old one though as a
scientific discipline sociology is not that old.
Sociology was introduced to India an academic discipline only after
world war I. Since then being closely allied with social philosophy and
anthropology, it emerged as an independent social science in the 19th century.
The Sociological thinking has gained some momentum in Bombay with
its mouthpiece "sociological bulletin" and in Agra with its organ "Journal of
social sciences". In the year 1919, sociology was first introduced in Bombay
University. Later in the year 1950. sociology was introduced in Mysore/Madras and Delhi universities. Some prominent sociologists of our country
like G.S.Ghurye. S.C.Dube, K.M Kapadia, M.N.Srinivas, Iravathi Karve,
A.R.Desai, P.N.Prabhu, K.N.Venkatarayappa. C.Parvathamma and many others have contributed their might to the enrichment of the discipline. Sociology is now taught in many universities as one of the major
disciplines. It has become more and more popular at the level of students
also.
