Unified Effort Measure for Natural Posturing of Digital Humans
Digital Human Models (DHMs) are extensively used in industrial ergonomic simulations to predict, understand, and analyse human behavior. However, most existing DHMs are built upon principles developed for robotic manipulators, ... -
Computational studies of the effect of confinement in Zeolitic cavities on the diffusion of monatomic Sorbates and the melting characteristics of Argon Clusters
The present chapter has attempted to study the temperature dependence of the levitation effect. It has been shown that this effect is most pronounced at lower temperatures and decreases in intensity at higher temperatures. ... -
Theortical studies of polar solvation dynamics, ionic mobility, solute diffusion and activated barrier crossing dynamicsin dense liquids
There are several features of this chapter that are new. The self-motion of the probe solute has been incorporated here for the first time and studied systematically. The theoretical approach captures quite successfully ... -
Computer simulation studies of orientational relaxation in strongly correlated dipolar systems
In the preceding three chapters of this thesis, computer simulation and theoretical studies of orientational relaxation in dipolar liquids and solids have been presented. The primary objective has been to understand the ... -
Investigation of fullerenes, Carbon nanotubes, Onions and small gold particles
Abstract not available -
Novel layered & three-dimensional oxides of perovskite & related structures: synthesis & investigation of ion-exchange & intercalation
In this chapter, we have described the synthesis of a new series of protonated layered perovskites of the formula, HCa???La?Nb???Ti?O??, from the corresponding potassium compounds by ion-exchange. The protonated compounds ... -
Theoretical studies of barrierless and very low barrier chemical reactions in solution
The above review of experimental investigations on the photophysics of stilbene and related compounds and the torsional dynamics of TPM in dyes in condensed phase clearly indicate a strong influence of viscosity and polarity ... -
Investigations of the interaction of molecules with clean and modified transition metal surfaces by techniques of electron spectroscopy
We have hitherto discussed the features of adsorbed oxygen on a variety of metal surfaces as characterised by the techniques of electron spectroscopy. Specifically, the characteristics of the different oxygen species O²?, ... -
Studies on porous iron electrodes for alkaline storage batteries and supplementary investigation on porous lead electrodes of lead-acid
It has been demonstrated that an analysis of the open-circuit transients is useful for understanding several aspects of the alkaline iron electrodes. It provides diagnostic criteria for studying the effect of additives. ... -
A Study of electronic structure and semiconductor-metal transitions in perovskite oxides
In this chapter we discuss the semiconductor-metal transition in La???Sr?CoO?. We study the electrical resistivity, X-ray photoelectron spectroscopy (XPS), Ultraviolet photoelectron spectroscopy (UPS), Auger electron ... -
Computer simulation studies of ionic motion in nasicon-type superionic conductors
In summary, a new interionic potential function for Li? with the Zr?(PO?)? framework of the LiZr?(PO?)? system, consisting of three terms-Coulombic, repulsive, and charge-polarizability interaction-has been proposed. ... -
Studies on the synthesis, Structure and Properties of Amine - Templated Arsenate frameworks
Amine-templated open-framework gallium arsenates with one- (I), two- (II and IV) and three-dimensionally (III–V) extended structures have been isolated and characterized. The exclusive presence of only one type of SBU in ... -
Novel layered and network metal oxides: synthesis and characterization.
The present investigation shows that reaction of electropositive metal iodides with the transition-metal oxides containing reducible cations affords a novel route for the synthesis of oxide bronzes as well as lower valence ... -
Electronic structure and Photophysical study of semiconducting nanocrystallites
Sizable photocurrent was observed from the CdS-4.5 and CdS-2.2 nanocrystalline films, although the EL efficiency was weak. The I-V characteristic of CdS-4.5 and CdS-2.2 has a typical diode behavior with the onset voltage ... -
Transport properties of binary mixture
In this paper, we have presented molecular dynamics (MD) simulations and mode coupling theory (MCT) calculations of the composition dependence of viscosity in binary mixtures. We have proposed two models to capture the ...
