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 .

A microelectromechanical system (MEMS) cantilever includes a base and a cantilever beam projecting from the base. The cantilever beam includes a piezo layer sandwiched between an inorganic material structural layer and an inorganic material encapsulating and immobilising layer. A pair of electrical contacts are formed in the encapsulating and immobilising layer in contact with the piezo layer. The base consists of polymer. A method includes depositing a sacrificial layer on a substrate; forming a MEMS cantilever beam on the sacrificial layer by depositing an inorganic material structural layer thereon; depositing a piezo layer on the structural layer; and depositing an inorganic material encapsulating and immobilising layer on the piezo layer; forming a pair of electrical contacts in the encapsulating and immobilising layer in contact with the piezo layer; forming a polymer base for the cantilever beam; and etching the sacrificial layer to release the MEMS cantilever beam from the substrate.

An apparatus for an in-vivo power generation comprises a fuel convertor for converting glucose in a fluid to a hydrogen rich, low carbon fuel such as ethanol or methanol by the action of a bioenzyme on the glucose in the CSF. The fluid can be any one of cerebro spinal fluid, urine and glucose solution. The apparatus further comprises a biofuel cell comprising a cathode chamber and an anode chamber with a membrane assembly sandwiched between them. The membrane assembly comprises a cathode, an anode and a proton exchange membrane. The cathode is coated with an enzyme laccase, which enables extraction of oxygen when the fluid is passed through the cathode chamber. The oxygen from the cathode chamber and the hydrogen in the hydrogen rich fuel from the anode chamber diffuses through the proton exchange membrane and reacts at an ionic level to result in water and electrical power.

A blade for a compressor rotor comprises a blade root at a first end of the blade extending from a rotor body of the compressor, and a blade tip at a second end of the blade. The first end and the second end are disposed on a span of the blade. The blade root and the blade tip define a face of the blade between them. The blade tip comprises a first extremity and a second extremity. The blade tip is disposed such that a first segment of the blade tip defines a positive dihedral angle with the face of the blade. The first segment extends from a first point in the blade tip to the first extremity of the blade tip. A second segment of the blade tip defines a negative dihedral angle with the face of the blade. The second segment extends from a second point in the blade tip to the second extremity of the blade tip.

A method and system for implementing DMPP tracking of partially shaded/uniformly illuminated photovoltaic arrays using switched capacitor DC-DC converter is disclosed. Here, a dedicated SC converter is connected across each PV cell or PV module made of series connected PV cells wherein series connected modules make a PV string and parallel connected PV strings make up a PV array. This SC converter injects an equalization current across the PV module or PV cell so that the total current in the parallel combination of the PV module or PV cell and the corresponding SC converter is the same as the PV string current. In another implementation of DMPP tracking using SC converters, a dedicated SC converter is connected across each isolated PV module to perform MPP tracking of the respective PV module. Then all MPP tracking SC converter outputs are diode ORed to the common load.
