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 ... -
Development of 2D and 3D Sketching Environment to Support Early Phases of Design
(2018-04-06)The traditional pen-paper sketching is extensively used in the early stages of product design as it supports creative exploration of product concepts and provides a fluidic mode for the expression of ideas. The Computer ... -

Interannual Variation of Monsoon in a High Resolution AGCM with Climatological SST Forcing
(2018-04-06)Interannual variation of Indian summer (June-September: JJAS) monsoon rainfall (ISMR) depends on its relative intensity during early (June-July: JJ; contribution 52%) and late (August-September: AS; contribution 49%) phases. ... -
Sensitivity of Sea Surface Temperature Intraseasonal Oscillation to Diurnal Atmospheric Forcings in an OGCM
(2018-04-05)Abstract The diurnal cycle is a dominant mode of sea surface temperature (SST) variability in trop-ical oceans, that influences air-sea interaction and climate processes. Diurnal variability of SST generally ranges from ... -
Influence of River Discharge on Climate in A Coupled Model
(2018-04-05)River discharge can affect ocean surface temperature by altering stratification within the oceanic mixed layer. A hitherto unexplored aspect of present climate is the feedback of river runoff onto climate. This thesis ... -
Smooth Finite Element Methods with Polynomial Reproducing Shape Functions
(2018-04-03)A couple of discretization schemes, based on an FE-like tessellation of the domain and polynomial reproducing, globally smooth shape functions, are considered and numerically explored to a limited extent. The first one ... -
Probabilisltic Analysis of Engineering Response of Fiber Reinforced Soils
