Development of Optimal Distributed Resource Utilisation Approaches Under Connectivity Constraints for Energy Internet
The global transition to sustainable power generation has driven a rapid increase in Distributed Energy Resources (DERs), especially from renewable sources. When integrated with energy storage, these localised generation ... -
Nonlinear mode theory of shear flow development
The major part of this thesis is concerned with the description of a new technique for analysing the development of shear layers (particularly in free flows). A principal feature of this method is the expansion of the ... -
On the migration of maximum tropical rain fall zone in a simple climate model
The aim of this thesis is to understand the seasonal migration of the maximum precipitation zone in the tropics (ITCZ) using a simple climate model. An attempt is also made to extract at least phenomenological answers to ... -
Effect of convex transverse surface curvature on transition and other properties of incompressible boundary layer.
A study of the incompressible boundary layer with transverse surface curvature has been made with particular reference to transition from laminar to turbulent flow. Calculations based on linearised hydrodynamic stability ... -
Design, development, and clinical validation of KaraMetrics: A sensor-based hand function assessment tool for stroke rehabilitation
Stroke is a leading cause of adult disability worldwide, with persistent hand dysfunction severely limiting independence and quality of life for survivors. Existing clinical assessments of hand function such as the Fugl-Meyer ... -
Core-Shell Precipitates in Ternary Alloys: A Phase-Field Study
Since the discovery of age hardening, a large number of alloys have been produced that exploit the presence of one or more precipitate phases in the microstructure for strength enhancement. In recent decades, alloys with ... -
Global response sensitivity and reliability analyses of structural dynamical systems with parameter and excitation uncertainties
This thesis develops computational methods for global response sensitivity analysis (GRSA) and time-variant reliability analysis in structural dynamical systems with parameter and excitation uncertainties. The primary ... -
Elastic Wave Dispersion Analysis and Mode Shape Investigation of Higher order Beam Theory for Thick Beams
The dynamic behavior of structural components, particularly thick beams, is critical in many engineering applications, including aerospace engineering, civil infrastructure, and mechanical systems. The rigid cross-section ... -
Automating SAPPhIRE Modeling for Product Systems and Extending SAPPhIRE Model to Service Representation
Creativity in product design sparks innovation, leading to unique solutions that meet evolving consumer needs. This innovation drives economic growth by creating new markets and job opportunities. Moreover, creative product ... -
Effect of flexible exit on vortex-pair generation
In the present work, we study experimentally the effect of flexible exit on vortex?pair generation. Vortex rings are frequently observed flow phenomena and have often been associated with unsteady starting jets issuing out ... -
Studies on sonoluminescence in the form of resonance radiation
Recent studies have shown that measured flash width from single and multibubble sonoluminescence are in the subnanosecond or even picosecond regime. Here we provide conclusive experimental evidence for the existence of ... -
Transient vibrations of one and two degree of freedon non-linear systems
This thesis is devoted to the study of transient vibrations of non-linear systems, with emphasis on two degree?of?freedom systems. After a résumé of the free and forced response of non-linear two degree?of?freedom systems, ... -
Dynamic viscosity of gas mixtures
An oscillating disc viscometer was designed and calibrated for the determination of viscosity of gases and gas mixtures at room temperature and pressure. The viscosity of oxygen, carbon dioxide and air were determined at ... -
Laminar buoyancy - induced flows and transport processes in stratified media
Buoyancy?induced flows in a density?stratified environment occur in a wide variety of engineering systems and in nature. Some of these are crystal growth processes, solar ponds, deep ocean power modules, environmental ... -
studies on silica and zircon sands bonded with silicate - ester systems
Introduction Cold-set processes have revolutionized mould and core-making techniques and have led to a reduced need for skilled labour. Chemical binders have made steady progress in the production of moulds and cores for ... -
Studies on drop formation at conical and capillary tips
Despite the role of drops being recognised in many metallurgical processes, surprisingly no significant progress has been made in this area. An understanding of the drop formation phenomenon is expected to give a better ... -
Electron spectroscopic studies of surface segregation and oxidation of Cu and Ni based alloys and low temperature preparation and characterization of intermetallics base on the system Fe-W-Mo
An overview of the surface studies on alloys reported in the literature and the objectives of the present investigationbave been presented in this chapter. Preparation and characterization of the various alloys studied ... -
Physical and mathematical modelling of boron carbide manufacturing process
Boron carbide is produced in a heat?resistance furnace using boric oxide and petroleum coke as the raw materials. In this process, a large current is passed through the graphite rod located at the center of the cylindrical ... -
Corrosion and related electrochemical studies on ziroconium (in nitrate melts, nitrats fluoride melts and aqueous nitrate solutions)
The thesis embodies the results of the investigations on the corrosion of zirconium in nitrate melts. The predicted thermodynamic behaviour of zirconium in 2-component NaNO?-KNO? eutectic melts based on E-pO diagrams ... -
Thermodynamic studies on the systems Ln-Fe-O (Ln = Nd, Sm, Dy)
Ternary oxides in the systems Ln–Fe–O (Ln = Nd, Sm, Dy) have been prepared by the citrate–nitrate route and characterised by X?ray diffraction analysis. The particle sizes of the ternary compounds were estimated to be in ...
