Investigations Of Polymer Grafted Lipid Bilayers Using Dissipative Particle Dynamics
(2011-01-25)Lipid molecules are amphiphilic in nature consisting of a hydrophilic head group and hydrophobic hydrocarbon tails. The lipid bilayer consists of two layers of lipid molecules arranged with their hydrophobic tails facing ... -
Construction of 3D CAD Models From 2D Orthographic Views
(2011-01-19)This thesis addresses the problem of constructing 3D CAD models from 2D engineering drawings of the object. Procedures for each step in the popular bottom-up approach are described. In each of the steps in this approach, ... -
Kinematic And Static Analysis Of Over-Constrained Mechanisms And Deployable Pantograph Masts
(2011-01-19)Foldable and deployable space structures refer to a broad category of pre-fabricated structures that can be transformed from a compact folded configuration to a predetermined expanded configuration. Such deployable structures ... -
Finite Element And Experimental Studies On Fracture Behavior Of Bulk Metallic Glasses
(2011-01-19)The objective of this thesis is to study the fracture behavior of bulk metallic glasses. For this purpose, detailed finite element investigation of the mode I and mixed mode (I and II) stationary crack tip fields under ... -
Cloud Properties Over SHAR Region Derived From Weather RADAR Data
(2011-01-18)Weather radars are increasingly used for the study of clouds, understanding the precipitation systems and also for forecasting very short range weather (one hour to a few hours). Now, Doppler Weather Radar (DWR) data are ... -
Cylindrical Fretting And Delamination : Axisymmetric Static And Dynamic Analysis
(2011-01-17)Axisymmetric analysis of cylindrical contacts is considered in the context of axisymmetric assemblies such as shrink-fits. Fretting fatigue induces sub-critical cracks along the contact interface of press fits especially ... -
Demonstration Of Supersonic Combustion In A Combustion Driven Shock-Tunnel
(2011-01-17)For flights beyond Mach 6 ramjets are inefficient engines due to huge total pressure loss in the normal shock systems, combustion conditions that lose a large fraction of the available chemical energy due to dissociation ... -
Fuzzy Dynamic Wave Models For Flow Routing And Flow Control In Open Channels
(2011-01-10)The dynamic wave model (the complete form of the saint-Venant equations), as applied to flow routing in irrigation canals or flood routing in natural channels, is associated with parameter and model uncertainties. The ... -
Steady State Dynamics Of Systems With Fractional Order Derivative Damping Models
(2011-01-10)Rubber like materials find wide applications in damping treatment of structures, vibration isolations and they appear prominently in the form of hoses in many structures such as aircraft engines. The study reported in this ... -
Identification Tools For Smeared Damage With Application To Reinforced Concrete Structural Elements
(2011-01-10)Countries world-over have thousands of critical structures and bridges which have been built decades back when strength-based designs were the order of the day. Over the years, magnitude and frequency of loadings on these ... -
Stabilised Rammed Earth For Walls : Materials, Compressive Strength And Elastic Properties
(2011-01-10)Rammed earth is a technique of forming in-situ structural wall elements using rigid formwork. Advantages of rammed earth walls include flexibility in plan form, scope for adjusting strength and wall thickness, variety of ... -
Static And Dynamic Behaviour Of Cement Stabilised Rammed Earth Panels And Building Models
(2011-01-10)Rammed earth is one of the earliest building materials used for structural walls. Stabilised rammed earth is a variant of traditional or pure rammed earth that involves addition of a small amount of cement to improve ... -
The Effect Of Interference Of Strip Foundations And Anchors On Their Ultimate Bearing Capacity And Elastic Settlement
(2011-01-10)Due to close proximity of different civil engineering structures, the ultimate bearing capacity and failure pattern of adjoining footings/anchors are often influenced by their mutual interference. The present thesis is an ... -
Analysis Of Precipitation Controls On Hydrochemistry Of A Groundwater System : Application To Upper Cauvery Basin : South India
(2011-01-10)Groundwater chemistry is a function of recharge and the input chemistry of the rain, which gets transformed as it moves through the soil matrix. Apart from mineral transformations, anthropogenic activities are other external ... -
