Active Vibration Control Synthesis Using Viscoelastic Damping Phenomena
(2011-07-12)In this thesis, a new method is followed to design an active control system which imparts viscoelastic phenomenological damping in an elastic structure. Properties of a hypothetical viscoelastic system are used to design ... -
Advanced Simulation Methodologies For Crashworthiness And Occupant Safety Assessment Of An Indian Railways Passenger Coach
(2013-05-21)Accidents involving passenger trains happen regularly in India. The reasons for such accidents could be many; such as weather and flooding, faulty tracks, bridge collapse, collisions caused by signaling errors, mechanical ... -
CFD Studies Of Pulse Tube Refrigerators
(2012-12-06)The performance evaluation and parametric studies of an Inertance Tube Pulse Tube Refrigerator (IPTR) are performed for different length-to-diameter ratios, with the Computational Fluid Dynamics (CFD) package FLUENT. The ... -
Characterization And Lime Stabilization Studies On Artificially Lead Contaminated Soils
(2011-07-08)Hazardous waste substances are solid, semi-solid or non-aqueous liquids that exhibit characteristics of corrosivity, reactivity, ignitability, toxicity and infectious property. Major available options for management of ... -
Characterization Of Al-Si Alloy Engine Bores For Tribological Studies
(2013-06-06)Aluminum - Silicon alloys are recognized as appropriate materials for high performance cast components used in transportation powertrain applications. A combination of excellent wear resistance, good thermal conductivity ... -
Defluoridation Of Drinking Water Using Activated Alumina
(2013-05-20)Excess fluoride (F-) in drinking water poses a health threat to millions of people around the world. In the present work, activated alumina (AA) has been used as an adsorbent. Data obtained from batch experiments were ... -
Design And Development Of An Improved Anti-Lock Braking System For Two-Wheelers
(2011-07-12)In today’s fast moving world, automobiles are facing challenges in terms of having to survive road accidents, increasing traffic, bad road-conditions and high/express ways. Brake systems play a vital role in controlling ... -
Development And Control Of Urban Water Network Models
(2013-10-17)Water distribution systems convey drinking water from treatment plant and make available to consumers’ taps. It consists of essential components like pipes, valves, pumps, tanks and reservoirs etc. The main concern in the ... -
Development Of A New Finite-Volume Lattice Boltzmann Formulation And Studies On Benchmark Flows
(2011-06-30)This thesis is concerned with the new formulation of a finite-volume lattice Boltzmann equation method and its implementation on unstructured meshes. The finite-volume discretization with a cell-centered tessellation is ... -
Dynamics And Stability Of A Launch Vehicle
(2011-07-08)Stability is an important criterion in the design and performance of launch vehicles. Present day launch vehicles have become more and more flexible due to the constraints of weight reduction, necessarily imposed for ... -
Effect Of Cross-sectional Nonlinearities On Anisotropic Strip-based Mechanisms
(2013-05-28)The goal of this work is to develop and demonstrate a comprehensive analysis of single and multi-body composite strip-beam systems using an asymptotically-correct geometrically nonlinear theory. The comprehensiveness ... -
Effect Of Squeeze Film Flow On Dynamic Response Of MEMS Structures With Restrictive Flow Boundary Conditions
(2011-07-08)There are many ways in which the surrounding media, such as air between an oscillating MEMS structure and a fixed substrate, can affect the dynamic response of a MEMS transducer. Some of these effects involve dissipation ... -
Enhancing The Potential Of Class F Fly Ashes For Geotechnical And Geoenvironmental Applications
(2013-07-19)Thermal power station in most countries is saddled with the problem of fly ash disposal and unless suitable avenues are found for its proper use, this would pose a gigantic problem to the power sector. Disposal of huge ... -
Evolution Of Texture And MIcrostructure During Processing Of Pure Magnesium And The Magnesium Alloy AM30
(2011-07-01)Magnesium is the lightest metal that can be used for structural applications. For the reasons of weight saving, there has been an increasing demand for magnesium from the automotive industry. However, poor formability at ... -
Experimental And Analytical Investigations Into Development Of Double-Tuned Expansion Chambers And Extended Concentric Tube Resonators
(2011-07-08)The performance of an acoustic filter (or muffler) is measured in terms of one of the following parameters: Insertion Loss (IL), Level difference (LD) and Transmission loss (TL). All these three parameters may be evaluated ... -
