Micro-scale Fracture Testing of Graded (Pt,Ni)Al Bond Coats
(2018-04-16)PtNiAl bond coats are diffusion aluminide coatings deposited on superalloy based turbine blades for oxidation resistance and improved adhesion between the substrate and the YSZ thermal barrier coating on top. They are ... -
Shock Tunnel Investigations on Hypersonic Impinging Shock Wave Boundary Layer Interaction
(2018-04-13)The interaction of a shock wave and boundary layer often occurs in high speed flows. For sufficiently strong shock strengths the boundary layer separates, generating shock patterns in the contiguous inviscid flow (termed ... -
Interdiffusion Study in Group IVB, VB and VIB Refractory Metal-Silicon Systems
(2018-04-13)The knowledge of diffusion parameters provides important understanding of many physical and mechanical properties of materials. In most of the applications silicides are grown by a diffusion controlled process mainly in ... -
Experimental Investigations on Supersonic Ejectors
(2018-04-13)A supersonic ejector is used to pump a secondary gas using a supersonic primary gas flow by augmentation of momentum and energy in a variable area duct. The internal compressible flow through an ejector has many complex ... -
Natural Hand Based Interaction Simulation using a Digital Hand
(2018-04-12)The focus of the present work is natural human like grasping, for realistic performance simulations in digital human modelling (DHM) environment. The performance simulation for grasping in DHM is typically done through ... -
Role of Composition, Structure and Physico-Chemical Environment on Stabilisation of Kuttanad Soil
(2018-04-12)Soft soil deposits of coastal regions and lowland areas pose many geotechnical problems but it is indispensable to utilize these grounds to meet the growing demand for infrastructure with ever increasing urbanization and ... -
Characterization and Assessment of Organically Modified Clays for Geo Environmental Applications
(2018-04-11)Clays are used for long for the control of soil and water pollution as they are inexpensive natural materials with a high adsorption capacity for a wide range of pollutants. However their use as components in engineered ... -
Mechanics and Mechanisams in Fretting Damage for Stainless Steel and Chromium Carbide Coatings
(2018-04-11)Fretting is a serious concern in many industrial components, specifically, in nuclear industry for the safe and reliable operation of the component/system. Till date, a lot of efforts has already been made to understand ... -
A Computational Study of Structural and Thermo-Mechanical Behavior of Metallic Nanowires
(2018-04-11)This thesis is an attempt to understand ways to improve thermo-mechanical and structural properties of nano-structured materials. A detailed study on computational design and analysis of metallic nanowires is carried out. ... -
Influence of Permeation of Synthetic Groundwater Solutions on the Hydro-Mechanical Proerties of Barmer Bentonite
(2018-04-11)The deep geological repository concept is based on “engineered barriers systems (EBS)” that are constructed in the repository and “natural barriers” provided by the surrounding geological environment. The EBS comprises of ... -
Establishment of an Experimental System in India to Measure the Mixing Ratio and Stable Isotopic Composition of Air CO2 & Observations from Urban and Marine Environments
(2018-04-11)The thesis presents observations on the CO2 mixing ratio and the carbon isotopic ratio (13C/12C i.e. δ13) of atmospheric CO2 from the Indian region, for the period 2008 - 2011. An experimental system was established at the ... -
Strength and Deformation Behavior of Municipal Solid Waste (MSW) Based on Constitutive Modeling Approach
(2018-04-11)The geotechnical properties of municipal solid waste (MSW) such as compressibility, shear strength and stiffness are of prime importance in design and construction of landfills. However, it is not well clear how the ... -
Thiophene Derivative Photovoltaics : Device Fabrication, Optimization and Study of Charge Transport Characteristics
(2018-04-11)In the recent years area organic photovoltaics is generating a lot of interests because whole process of synthesis and fabrication is less energy intensive process as well as it is cost effective compared to conventional ... -
Predictability of Nonstationary Time Series using Wavelet and Empirical Mode Decomposition Based ARMA Models
(2018-04-06)The idea of time series forecasting techniques is that the past has certain information about future. So, the question of how the information is encoded in the past can be interpreted and later used to extrapolate events ... -
