Modeling and rendering of fluid volumes with particle systems
Visualization of fluid volumes is necessary in a wide range of applications. Scientific studies of fluid dynamics require the visualization of results of computations. Real?world scenes often contain fluids in the form of ... -
Studies in organo arsenicals
The present thesis consists of four parts, preceded by “A Brief Résumé of the Literature on Organo?Arsenicals.” Under this heading, various aspects of the problems of organo?arsenicals have been considered in good detail, ... -
N1 and N4 substituted sulphanilamides : Synthesis of N- substituted, (anils, ancyls, sulphony1, and azo)-derivatives of sulphathiazole and sulphapyridine
The present thesis consists of five parts, of which the first two deal with the preparation of the two well?known sulphanilamide drugs, sulphathiazole and sulphapyridine, and of their starting materials. The last three ... -
The use of dual quaternions in rigid body motion interpolation and visualization
Dual quaternions are an excellent alternative tool to transformation matrices in the study of rigid body motion. They are known to represent the position and orientation of a rigid body in a concise and efficient manner, ... -
Interface capturing in multiphase flows using finite volume based level set method
An important class of problems involves a substance transforming from one phase to another with absorption or emission of energy. Such cases arise in many settings, of which melting, solidification, condensation, and ... -
Constrained least squares finite element formulation of two-dimensional elastodynamic problems
In the present work, a least?squares finite element formulation for two?dimensional elastodynamic problems is developed. This development is based on an earlier formulation reported by Pratap. The earlier formulation was ... -
Experimental study of endwall flow in a compressor cascade
Improvement in calculating methods for end?wall boundary layers of blade rows can only come about by a greater understanding of the physics of the flow from which realistic models can be built of the terms that go into ... -
Electronic signal processing in laser doppler annemometry
The three commonly used electronic processors for laser Doppler anemometer systems are the spectrum analyser, the frequency tracking demodulator and the period timing device. Extensive analytical studies on spectrum analyser ... -
Boundary layer transition with and without lateral divergence
Information on the transition processes in turbomachine boundary layers is important in computing schemes for predicting blockage, flow losses, separation, etc. Actual transition on turbomachine blades does not conform to ... -
An Experimental Study On The Scale Effects In Cavitation Noise
Cavitation noise studies were made in a water tunnel with particular reference to scale effects. Travelling?bubble cavitation was artificially generated on four axisymmetric bodies of the Schiebe head?forms with varying ... -
Rational approach to solid finite elements
The finite element method today has become a powerful tool in engineering analysis and design. The ease of application, reliability of solutions, and its ability to model complex geometries seem to be the main reasons for ... -
Studies on viscosity of mixtures of some freon vapours
An oscillating disc viscometer is used for the determination of viscosity of Freon?12, Freon?22 and Freon?114 vapours and their binary and ternary mixtures at room temperature and pressure. The viscosity of Freon?12, ... -
Studies on viscosity of mixtures of freon-12 and freon 22 vapours
The viscosity of pure Freon?12 and Freon?22 vapours, and their mixtures, has been determined using an oscillating?disc viscometer at room temperature and pressure. The results agree well with the published data for the ... -
Production of aromatic alcohols and hydroxy acids by candida species and the mode of action of aromatic alcohols
The thesis entitled “Alcohols and Hydroxy Acids by Candida Species and Their Mode of Action”, submitted by Mr. T. K. Narayanan for the Ph.D. degree of the Indian Institute of Science, Bangalore–560012, India. Yeasts, in ... -
Cyclic peptide disulfides as conformational models; synthesis and spectroscopic studies
The study of small peptides has been motivated both by the high biological activity manifested by many peptides and their potential use as model systems for understanding polypeptide and protein structure. The development ... -
conformational studies on hydrogen bonded cyclic hexapeptides
In the first place, the uniqueness of any MEC within a certain region demonstrates the successful incorporation of the hydrogen?bond energy function in a minimization program. In particular, its interpolation with the ... -
CONFORMATION OF POLYNUCLEOTIDES
The conformations of the five?membered rings and other relevant conformational features of deoxyribose, ribose, and arabinose have been analysed in this chapter and in the preceding two chapters. The analysis included ... -
X-ray crystallographic studies on the structure and interactions of L-ascorbic acids
It is well known that non?covalent interactions endow biological systems with extreme subtlety and complexity. In fact, the structure and assembly of proteins, and the dynamical processes involved in their action, are ...
