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 .

Embodiments herein provide an implantable Flow Streamliner for passively regulating blood streams in a TCPC subject. The implantable Flow Streamliner is configured to split a blood stream from an Inferior Vena Cava (IVC) and a blood stream from a Superior Vena Cava (SVC), without a direct collision between the blood streams. Further, the implantable Flow Streamliner is configured to distribute the blood stream from the IVC containing hepatic nutrients in proportion to a Left Pulmonary Artery (LPA) and a Right Pulmonary Artery (RPA). Further, the implantable Flow Streamliner is configured to distribute the blood stream from the SVC in equal proportion to the LPA and the RPA.

A network capable of being used in a datacenter is described. The network can comprise a set of optical fiber rings, wherein each optical fiber ring carries data traffic on multiple wavelengths, and wherein each optical fiber ring is partitioned into multiple sectors. In some embodiments, each sector in the multiple sectors can comprise: (1) only one add-wavelength-selective-switch (add-WSS) communicatively coupled to only one optical fiber ring in the set of optical fiber rings, wherein the only one add-WSS is used for sending all data traffic that originates from the sector and is destined to other sectors; (2) an add-electro-optical-switch (add-EOS) communicatively coupled to the add-WSS; (3) a set of drop-wavelength-selective-switches (drop-WSSs) communicatively coupled to the set of optical fiber rings, wherein the set of drop-WSSs are used for receiving data traffic from other sectors; and (4) a drop-electro-optical-switch (drop-EOS) communicatively coupled to a drop-WSS in the set of drop-WSSs.


A method for speech enhancement in speech communication devices and more specifically in hearing aids for suppressing stationary and non-stationary background noise in the input speech signal signals is disclosed. The method uses spectral subtraction wherein the noise spectrum is updated using quantile-based estimation without voice activity detection and the quantile values are approximated by dynamic quantile tracking without involving large storage and sorting of past spectral samples. The technique permits use of a different quantile at each frequency bin for noise estimation without introducing processing overheads. The preferred embodiment uses analysis-modification-synthesis based on Fast Fourier transform (FFT) and it can be integrated with other FFT-based signal processing techniques used in the hearing aids and speech communication devices. A noise suppression system based on this method and using hardware with an audio codec and a digital signal processor chip with on-chip FFT hardware is also disclosed.

The ion and molecular recognition properties of 1, 3-diconjugates of calix[4]arene were studied. These recognitions were carried out in different solvent systems by using various spectroscopy techniques, and in some cases the species of recognition have been demonstrated by single crystal X-ray structure determination and/or by computational modeling studies. An aspect that requires further attention is the aqueous solubility of calix[4]arene conjugates. It is possible to build more binding sites on the calix[4]arene platform by introducing various donor groups in the vicinity of the lower rim phenolic group of calix[4]arene to provide higher coordination for lanthanides and other demanding ions. All of these receptors primarily possesses O- and N-binding centers, but are mostly deprived of carboxylato- and/or thiolato-moieties that may be required to mimic the selective recognition of metal ions by the corresponding apo-proteins.

Clinical translation and feasibility of tissue-engineered constructs depend on several factors which include the source of cells used, the properties of the scaffolds, and the signaling molecules. The region of origin and the state of differentiation of the chondrocytes seem to control the cellular response. Long-term culture of chondrocytes derived from young donors with high initial cell seeding density shows good results with respect to growth rate, in vitro expansion, and biosynthesis. Hydrogels derived from biopolymers have synergistic beneficial aspects of water swelling, cartilage-like behavior of hydrogel, as well as extracellular matrix mimicking property of biopolymers. The poor mechanical stability of these matrices and nonadhesive nature of cells onto the surface have been rectified to some extent by the hybridization of biopolymers with synthetic polymers and incorporation of peptides. Much attention should be given to develop injectable hybrid systems as those systems can solve the issues related with targeted minimal invasive delivery, biocompatibility, and mechanical strength.
