Application of programming languages for processing natural languages with special reference to english and tamil
The program development has led to the following applications: i) Linguists working on various aspects of language, and ii) computer users who would like to use one of their own languages for linguistic data processing. Among ... -
Casing boundary layer decelopment in axial impellers with TIP clearence
Casing wall boundary layers are heavily skewed under the action of secondary and tip clearance flows, relative wall motion and the transverse forces associated with the blade rows. The growth of the casing boundary layers ... -
Charged solution excitations and the vaccum state of.. field theories
This thesis describes some theoretical investigations on ?? field theories (i.e., theories governed by Lagrangians which are sixth-degree polynomials in ?) where ? is either a real or a complex scalar field. We work in ... -
Chemical process deveoopment for sodium dithionite- a kinetic study of sodium formate process
(1) The kinetics of formation of sodium dithionite has been investigated in homogeneous aqueous phase. The rate of hydrolysis of sodium formate has been found to be the rate?controlling step. The following rate equation ... -
Contributions to the development of computationally efficient clustering techniques
The concept of multilevel theory is applied in this thesis to reduce the computation and storage requirements of various existing clustering algorithms. At the first level, the data is divided arbitrarily into a number of ... -
Critical dielectric constant measurements and high pressure phase diagram studies in binary liquid sytem
The main conclusions of the present study have been summarised below. The data have been fitted to the extended scaling equation: C = C? (A t + B t? + …) The present study shows that the exponent (?) characterising the ... -
Dihydrobenzenes in organicsynthesis
The thesis entitled “Dihydrobenzenes in Organic Synthesis” consists of three chapters. Chapter I Chapter I deals with a brief introduction to the addition of electrons to unsaturated systems, in particular monobenzenoid ... -
Electrical discharges in mercury vapour in a magnetic field
Langmuir probe method is applied to determine the n? and T? of a low-density, collisional plasma in mercury vapour under moderate magnetic field strengths. The charge density evaluated by Bohm's method and the orbital ... -
Electrical resistance and dielectric constant studies in a binary liquid system in the critical region
This thesis presents an experimental investigation of electrical resistance and dielectric constant anomalies in a critical binary liquid system (the polar + non-polar mixture methanol + cyclohexane). Since the critical ... -
Empirical investigations of the applicability of sampling techniques for inventory valuation by computer simulation
Industrial engineering techniques such as work simplification and methods improvement have become increasingly important as industries, under the stimulus of intense competition, strive to improve operational efficiency ... -
Gaseous breakdown below paschen minimum in ExB fields
Some investigations about the electric discharge in a coaxial geometry electrode are explained in the transition range, namely, Townsend–Penning discharge for the dry air. The existing theory of 0.05 to 0.3 Torr is extended ... -
INVESTIGATIONS ON Positive Temperature Coefficient of Resistance OF POLYCRYSTALLINE BARIUM TITANATE
The way similar to monomerisation or at higher temperatures. CD studies indicated no major change in the secondary structure of the proteins of lipovitellins during chloroform absorption. The interaction of Ca²? and Na? ... -
Kinetics and mechanism of the transient behaviour of magnesium anodes
The main objective of the present investigation is to study the mechanism of delayed dissolution of magnesium anodes during discharge of magnesium dry cells. A supplementary part of the work is devoted to the development ... -
Mass spectroscopic and some optical spectroscopic studies ontrace element analysis in solids
This thesis deals with certain aspects of the chemical analysis of solids, viz., the accuracy and precision of measurements and phenomena connected with RF?spark and other discharge processes. Results have been obtained ... -
Raman and infrared study of vibrational and rotational relaxations
Our data on the area-ratio of the split components of the Ag Raman line in potash alum show a clear departure from the Boltzmann distribution at temperatures below 150 K. Modification of the phonon-induced transition rates ... -
Some reactions of oximes and related topics
The thesis entitled “Some Reactions of Oximes and Related Topics” is divided into four chapters. Chapter I This chapter describes a new reaction of oximes wherein ?? and ??acetoxyenamides (2, 3) are obtained from ketoximes ...
