Barry Ramachandra Rao
Barry Ramachandra Rao (21 November 1922 – 24 September 2005) was an Indian space physicist and the vice chairman of the University Grants Commission of India. Known for his pioneering research in radio physics, Rao was a Member of Parliament of the Rajya Sabha and an elected fellow of all the three major Indian science academies viz. Indian Academy of Sciences, Indian National Science Academy and National Academy of Sciences, India.

Visakhapatnam District
Visakhapatnam district (formerly known as Vizagapatam district) is one of the six districts in the Uttarandhra region of the States and union territories of India, Indian state of Andhra Pradesh, headquartered at Visakhapatnam. It is one of the twenty-six List of districts of Andhra Pradesh, districts in Andhra Pradesh state.The district share broders with in the north and east, Vizianagaram district and South Anakapalli district in the south-west and Bay of Bengal in the south. History During the British Raj, British rule in India, Visakhapatnam emerged as a district in the year 1802. Chicacole (present-day Srikakulam) which was in Visakhapatnam district was incorporated into Ganjam when the latter was formed as a district. On 1 April 1936, Bihar and Orissa Province was split to form Bihar Province and Orissa Province. Parts of the Vizagapatam district (Madras Presidency), Vizagapatam district (i.e., Nabarangpur, Malkangiri, Koraput, Jeypore, Rayagada etc.) and the Ganjam ...

Oscillograph
An oscilloscope (informally a scope) is a type of electronic test instrument that graphically displays varying electrical voltages as a two-dimensional plot of one or more signals as a function of time. The main purposes are to display repetitive or single waveforms on the screen that would otherwise occur too briefly to be perceived by the human eye. The displayed waveform can then be analyzed for properties such as amplitude, frequency, rise time, time interval, distortion, and others. Originally, calculation of these values required manually measuring the waveform against the scales built into the screen of the instrument. Modern digital instruments may calculate and display these properties directly. Oscilloscopes are used in the sciences, medicine, engineering, automotive and the telecommunications industry. General-purpose instruments are used for maintenance of electronic equipment and laboratory work. Special-purpose oscilloscopes may be used to analyze an automotive ign ...

Bragg's Law
In physics and chemistry , Bragg's law, Wulff–Bragg's condition or Laue–Bragg interference, a special case of Laue diffraction, gives the angles for coherent scattering of waves from a crystal lattice. It encompasses the superposition of wave fronts scattered by lattice planes, leading to a strict relation between wavelength and scattering angle, or else to the wavevector transfer with respect to the crystal lattice. Such law had initially been formulated for X-rays upon crystals. However, It applies to all sorts of quantum beams, including neutron and electron waves at atomic distances, as well as visible light at artificial periodic microscale lattices. History Bragg diffraction (also referred to as the Bragg formulation of X-ray diffraction) was first proposed by Lawrence Bragg and his father, William Henry Bragg, in 1913 in response to their discovery that crystalline solids produced surprising patterns of reflected X-rays (in contrast to that of, say, a liquid). They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diffraction Pattern
Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. The diffracting object or aperture effectively becomes a secondary source of the propagating wave. Italian scientist Francesco Maria Grimaldi coined the word ''diffraction'' and was the first to record accurate observations of the phenomenon in 1660. In classical physics, the diffraction phenomenon is described by the Huygens–Fresnel principle that treats each point in a propagating wavefront as a collection of individual spherical wavelets. The characteristic bending pattern is most pronounced when a wave from a coherent source (such as a laser) encounters a slit/aperture that is comparable in size to its wavelength, as shown in the inserted image. This is due to the addition, or interference, of different points on the wavefront (or, equivalently, each wavelet) that travel by paths of diff ...

Ultrasonics
Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from "normal" (audible) sound in its physical properties, except that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning, mixing, and accelerating chemical processes. Animals such as bats and porpoises use ultrasound for locating prey and obstacles. History Acoustics, the science of sound, starts as far back as Pythagoras in the 6th century BC, who wrote on t ...

University Grants Commission (India)
University Grants Commission (UGC) is a statutory body set up by the Department of Higher Education, Ministry of Education, Government of India in accordance to the UGC Act 1956 and is charged with coordination, determination and maintenance of standards of higher education in India. It provides recognition to universities in India, and disbursements of funds to such recognized universities and colleges. The headquarters are in New Delhi, and it has six regional centres in Pune, Bhopal, Kolkata, Hyderabad, Guwahati and Bangalore. A proposal to replace it with another new regulatory body called HECI is under consideration by the Government of India. The UGC provides doctoral scholarships to all those who clear JRF in the National Eligibility Test. On an average, each year is spent on doctoral and post-doctoral fellowships by the commission. History The UGC was first formed in 1945 to oversee the work of the three Central Universities of Aligarh, Banaras and Delhi. ...

Doctor Of Science
Doctor of Science ( la, links=no, Scientiae Doctor), usually abbreviated Sc.D., D.Sc., S.D., or D.S., is an academic research degree awarded in a number of countries throughout the world. In some countries, "Doctor of Science" is the degree used for the standard doctorate in the sciences; elsewhere the Sc.D. is a "higher doctorate" awarded in recognition of a substantial and sustained contribution to scientific knowledge beyond that required for a Doctor of Philosophy (PhD). Africa Algeria and Morocco In Algeria, Morocco, Libya and Tunisia, all universities accredited by the state award a "Doctorate" in all fields of science and humanities, equivalent to a PhD in the United Kingdom or United States. Some universities in these four Arab countries award a "Doctorate of the State" in some fields of study and science. A "Doctorate of the State" is slightly higher in esteem than a regular doctorate, and is awarded after performing additional in-depth post-doctorate research or ach ...

Osmania University
Osmania University is a collegiate public state university located in Hyderabad, Telangana, India. Mir Osman Ali Khan, the 7th Nizam of Hyderabad in 1918 , He released a farman to establish OSMANIA UNIVERSITY on the day of 28 August 1918. It is the third oldest university in southern India, and the first to be established in the erstwhile Kingdom of Hyderabad. It was the first Indian university to have Urdu as a medium of instruction — but with English as a compulsory subject. As of 2012, the university hosts 3,700 international students from more than 80 nations. The O.U. is one of the largest university systems in the world with over 300,000 students on its campuses and affiliated colleges. The Osmania Medical College was once a part of the O.U. System. However, it is now under the supervision of Kaloji Narayana Rao University of Health Sciences. History The Osmania University was brought into existence in 1918 through a '' firman'' of ''Mir Osman Ali Khan'', the l ...
