Ab initio quantum chemical studies on the molecular geometry, force field and vibrational spectra of diborane and related compounds .
A good quality force?constant set for a polyatomic molecule can be derived from ab initio calculations using the L?matrix without recourse to arbitrary scale factors or extra computational effort. The RECOVES procedure can ... -
Algorithms for coloring random and semi-random graphs
The graph coloring problem is NP-hard and arises in a variety of practical situations. Recent breakthroughs in the area of approximation complexity indicate that it is not possible (unless P = NP) even to approximate the ... -
Amylases From A Thermophilic Fungus Thermomyces Lanuginosus Iisc 91 :Their Purification And Properties
(Indian Institute of Science, 2005-04-06)A knowledge of molecular properties and structure of heat-stable enzymes is important for the understanding of basic principles governing thermo stability of proteins and evolution of life at high temperatures. Information ... -
Antigenic Determinants Of Chicken Riboflavin Carrier Protein: Structural And Functional Aspects
(Indian Institute of Science, 2005-09-01)Investigations detailed in this thesis constitute a part of the continuing programme of research undertaken in our laboratory on the riboflavin carrier protein (RCP) with particular reference to identification and synthesis ... -
Application of trust region on methods to learning in feed forward neural networks
This thesis presents a novel algorithm for training feed-forward neural networks, addressing the limitations of the widely used back-propagation and Quickprop algorithms. While Quickprop is significantly faster than standard ... -
Aqueous Phase Oxidation Of Sulfur Dioxide In Stirred Slurry Reactors
(Indian Institute of Science, 2005-07-18)Air pollution by sulfur dioxide is of great concern due to its harmful effects on environment, human beings, fauna and flora. Fossil-fuel-fired power plants are one of the major sources of SO2 emissions. Typically the ... -
Asymmetric Synthesis Of Troger's Base Analogues And Studies In Molecular Recognition
(Indian Institute of Science, 2005-04-25)Troger's base was the first amine to be resolved where the chirality was due to solely very high inversion barrier around nitrogen atom. Though the molecule was known for over a century, work done during the past decade ... -
Autonomous Orbit Estimation For Near Earth Satellites Using Horizon Scanners
(Indian Institute of Science, 2005-10-20)Autonomous navigation is the determination of satellites position and velocity vectors onboard the satellite, using the measurements available onboard. The orbital information of a satellite needs to be obtained to support ... -
Biodegradation Of 1-Naphthoic Acid
(Indian Institute of Science, 2005-04-06)Polycyclic aromatic hydrocarbons (PAHs) are compounds containing carbon and hydrogen atoms of fused benzene rings in linear, angular or cluster arrangements. These compounds have a large (negative) resonance energy, resulting ... -
Carbon potential in U-Pu-C-O-N system: measurements and calculations
The Fast Breeder Test Reactor (FBTR) at the Indira Gandhi Centre for Atomic Research, Kalpakkam, presently employs mixed carbide with a Pu/(U + Pu) ratio of 0.70 as fuel. It is envisaged that the second core of the reactor ... -
Characterisation Of DNA Llgase And Pairing Activities From A Partially Purified Fraction From Rat Testis
(Indian Institute of Science, 2005-04-06)Homologous genetic recombination is a central feature of meiosis in most sexually dividing organism. It leads to the establishment of new linkage relationships between genes and is crucial for the successful completion of ... -
Characterization of ligand binding in ribonuclease a computer modelling and simulation approach
In recent times, the fields of biochemistry, molecular biology, structural studies, and biomolecular computation have moved closer to each other and are now interconnected. Often, the inputs from one discipline can serve ... -
Chemorhelogical Modeling Of Amine-Cured Multifunctional Epoxy Resin Systems Used As Matrices In Aerospace Composites
(Indian Institute of Science, 2005-07-13)High performance multifunctional epoxy resin systems are becoming increasingly important as matrix materials for the advanced composites used in aerospace, electronics, automotive and other industries. In a composite based ... -

Cloning and Expression of a Diagnostic Antigen for Invasive Amoebiasis
(Indian Institute of Science, 2005-04-29)A crude extract of axenically grown amoebae was used as antigen in order to develop an AB microELISA for the detection and quantitation of E. histolytica-specific IgG antibodies. This ELISA was used to screen individual ... -
Clustering For Designing Error Correcting Codes
(Indian Institute of Science, 2005-02-11)In this thesis we address the problem of designing codes for specific applications. To do so we make use of the relationship between clusters and codes. Designing a block code over any finite dimensional space may be thought ... -
