Theoretical studies on models for organic ferromagnetism
The thesis examines the three models in existence which predict ferromagnetism in purely organic systems. These models are (i) Mataga-Ovchinnikov model which predicts high-spin ground state in alternant polymers with ... -
Theoretical and experimental studies on open circuit voltage decay lifetime and series resistance in solar cells and other P-N junction devices
Open-Circuit Voltage Decay (OCVD) is a simple and widely used technique for determining the minority carrier lifetime (??) in p–n junction devices. In this work, theoretical expressions for both Forward Current-Induced ... -
Theoretical studies on some classical and quantum transport problems in random media
The problem of transport of charge (electrons, holes and ions) and energy (excitons) in a dynamically disordered medium is assuming increasing significance in recent times, from theoretical and experimental viewpoints. ... -
Studies on the raman spectra of crystals (PHY)
The Raman spectra of crystals have formed a very fruitful topic of study in the past and such studies, particularly on single crystals in specific orientations, have contributed in a large measure to a better understanding ... -
Improving Mechanical Properties and Self-Healing by Dynamic Bonds at Interface in Carbon Fiber Reinforced Epoxy Laminate and its Recycling
Carbon fiber-reinforced epoxy (CFRE) laminates have revolutionized aerospace engineering due to their exceptional strength-to-weight ratio, corrosion resistance, and design flexibility. However, challenges such as weak ... -
Capital-output ratios and their behaviour
The purpose of the present investigation is to examine empirically whether or not the capital-output ratio is a technological coefficient and a constant, within the basic framework of the macro-dynamic model of Kaldor and ... -
Study of context, structure and performance of organisations
In the present study, relationships between contextual and structural variables and the prediction of the structural dimensions from the contextual dimensions have been attempted. Thirdly, both of the contextual and ... -
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 ... -
Study of the dynamics of wage determination of industrial employees in india
Employee remuneration of industrial workmen is a major unresolved conflict area in the field of industrial relations in India because about 40% of industrial disputes relate to wage issues. The changing concept and context ... -
Satisfaction and Productivity: A Study of Morale and Team Work in Industry With Respect to Productivity
The present study is an attempt at contributing to our understanding of the problems of satisfaction and productivity in the work groups of industry. The cultural setting of India, in which this investigation has been ... -
Dividends, investment, and external financing behaviour of public limited companies in the engineering inndustry in India
The interdependence between dividends, investment, debt, and equity financing has been studied within the context of both the single equation and simultaneous equation models using cross-section data on the Indian engineering ... -
Some studies on resistance to flow in rigid bed open channels
This thesis embodies the results of the investigations carried out by the author on the problem of resistanc-e to flow through open channels. Based on these> the author was able to modify Manning's formula, so as to ... -
Prediction of cavitation damage
A theory which gives a unified picture of (1) the bubble collapse, (ii) the transmission of the collapse pressure, and (iii) the deformation of the material due to the work done by the bubble is proposed, incorporating ... -
Studies on air entrainedflow
The important factors affecting air entrainment by flowing water are found to be slope and roughness. Results showing the effect of slope, length of the chute, side wall, and different conditions of roughness are presented ... -
Studies on submerged jets
This thesis deals with the studies on submerged jets. In the first part of the thesis, a critical survey of the existing literature has been made with a bibliographical chart on the subject up to date. The second part ... -
Studies on the resistance to the flow of water in curved pipes and pipe bends
This thesis contains the theoretical and experimental investigations carried out by the author on the resistance offered to the flow of water curved curved pipes and pipe bends The thesis is in three parts In Part I » ... -
Dispersive Superconducting Circuit Quantum Electrodynamics, the Time-continuous Feynman’s Light Microscope and Non-Markovian dynamics in multi-mode Superconducting Circuits
This thesis is divided into three parts, with each part concerned with one of the three pillars of Theoretical Quantum Optics: ‘Microscopic models of Light-Matter Interaction’, ‘Quantum Measurements’ and finally, ‘Driven ... -
On some themes and models in economics (with a case-study in management)
The case study has sought to draw attention to the fact that historical factors have a strong impact on the structure and behaviour of a company. In the case of HMT, some of these factors were the association with the ... -
Symbolic processings of polynomia matrices using finite field transforms (Polynomial matrix-processor system design)
A new representation of the rational polynomials with integral coefficients over a finite field by expressing each of their coefficients in a suitable prime base is outlined. A modified form of this representation using ... -
Some studies in location and scheduling problems
The location and scheduling problems considered in this study are special cases of what are called combinatorial models. A combinatorial optimization problem consists of finding, from among a finite set of alternatives, ...
