The Indian Institutes of Technology is a prestigious group of autonomous public engineering and management institutes of India. The IITs are governed by the Institutes of Technology Act, 1961 which has declared them as "institutions of national importance", and lays down their powers, duties, framework for governance etc. The Institutes of Technology Act, 1961 lists sixteen institutes located at Bhubaneswar, Chennai, Delhi, Gandhinagar, Guwahati, Hyderabad, Indore, Jodhpur, Kanpur, Kharagpur, Mandi, Mumbai, Patna, Ropar, Roorkee and Varanasi. Each IIT is an autonomous institution, linked to the others through a common IIT Council, which oversees their administration. The IITs award degrees ranging from B.Tech to PhD.The IITs have a common admission process for undergraduate admissions. It was called IIT-JEE, which was replaced by Joint Entrance Examination in 2013. The post-graduate level program that awards M.Tech degree in engineering is administered by the older IITs . M.Tech admission is done on the basis of Graduate Aptitude Test in Engineering . In addition to B.Tech and M.Tech programs IITs also award other graduate degrees such as M.Sc in Engineering, Maths, Physics and Chemistry, MBA, PhD etc. Admission to these programs of IITs is done through Common Admission Test, Joint Admission Test for Masters and Common Entrance Examination for Design .

Indian Institute of Technology Madras | Date: 2015-04-27

The invention includes a method for predicting the operational state of equipment with turbulent flow characterized by time series data relating to its operation. The invention further includes a system and method for predicting the onset of an impending oscillatory instability. Further, the invention includes a system and method for identifying an impending absorbing transition such as flame blowout in combustion systems. A variable representing the dynamics of operation is measured with the help of a sensor, to obtain time series data. A complex network is then derived from the measured time series data. Network properties are then calculated using the complex network to identify the state of stability relating to operation of the equipment. The stability information may include one of thermoacoustic instability, aero-elastic instability such as flutter, flow-induced vibration, magneto-hydrodynamic, aerodynamic, aeromechanical, aero-acoustic instability or onset of flame blowout of a combustor.

Compositions comprising an antagonist of pancreastatin are provided. The beneficial use of the compositions for treating insulin resistance, diabetes, especially type II diabetes, inflammation, obesity, non-alcoholic fatty liver disease, atherosclerosis and cardiovascular diseases is described as well.


The embodiments herein provide an energy storage battery system constituting multiple banks of individual batteries, each of which may have different characteristics, and methods of operation of the system. The multiple battery banks configuration is based on split battery configuration derived by a splitter based on a probability distribution function (pdf) of expected usage pattern, optimization goal, and battery characteristics of a corresponding single battery system. The energy system optimizes at least one of cost, weight or size of the overall system by rotating usage of various battery banks based on usage pattern.

Lanczos-Lovelockmodels of gravity represent a natural and elegant generalization of Einstein's theory of gravity to higher dimensions. They are characterized by the fact that the field equations only contain up to second derivatives of the metric even though the action functional can be a quadratic or higher degree polynomial in the curvature tensor. Because these models share several key properties of Einstein's theory they serve as a useful set of candidate models for testing the emergent paradigm for gravity. This review highlights several geometrical and thermodynamical aspects of Lanczos-Lovelockmodels which have attracted recent attention. © 2013 Elsevier B.V.
