Water Balance Studies In A Small Experimental Forested Watershed, South India
(2011-04-01)Forested watersheds play a dominant role in the global hydrological cycle. Very few experimental observatories especially in tropical forested regions of India have been undertaken. This study has been initiated for this ... -
Analytical Models For Stress-Strain Response Of Fiber-Reinforced Soil And Municipal Solid Waste
(2011-04-01)The present thesis proposes model for the analyses of stress-strain response of fiber reinforced soil and municipal solid waste (MSW). The concept of reinforcing soils by introducing tension resisting elements such as ... -
Regional Frequency Analysis Of Hydrometeorological Events - An Approach Based On Climate Information
(2011-04-01)The thesis is concerned with development of efficient regional frequency analysis (RFA) approaches to estimate quantiles of hydrometeorological events. The estimates are necessary for various applications in water resources ... -
Creep, Wear And Corrosion Behaviour Of Novel Magnesium Alloys And Composites
(2011-04-01)In the present investigation, MMCs have been fabricated using the creep-resistant AE42 magnesium alloy as matrix and reinforcing it with saffil short fibres (essentially δ-Al2O2) and SiC particles in various combinations. ... -
Studies On Surface Aeration In Circular Tanks
(2011-04-01)Water is a fundamental need for existence of mankind. Only 0.01 % of total global water is readily available for human consumption as fresh water. The rapid increase in human population and consequent rise in urbanization ... -
Response And Reliability Analyses Of Soil Nail Walls
(2011-04-01)In the present thesis, studies on the response of soil nail walls subjected to static and seismic conditions using finite element based numerical simulations and the principle of reliability analysis have been performed. ... -
Structure And Dynamics Of Interfacial And Confined Water
(2011-03-28)Understanding the structure and dynamics of molecularly thin films or the state of water confined to nanoscale dimensions is an active field of research and has wide applications in areas ranging from biology to geology. ... -
Time Scale Separated Nonlinear Partial Integrated Guidance And Control Of Endo-Atmospheric Interceptors
(2011-03-17)To address the concern of classical guidance and control designs (where guidance and control loops are designed separately in an “outer loop – inner loop” structure), integrated guidance and control (IGC) ideas have been ... -
Structure Of Sink Flow Boundary Layers
(2011-03-17)The work reported in this thesis is an experimental and theoretical investigation of the so-called sink flow boundary layers. These are two-dimensional (in the mean), favourable-pressure-gradient (FPG) boundary layer flows ... -
Speech Signal Classification Using Support Vector Machines
(2011-03-16)Hidden Markov Models (HMMs) are, undoubtedly, the most employed core technique for Automatic Speech Recognition (ASR). Nevertheless, we are still far from achieving high‐performance ASR systems. Some alternative approaches, ... -
Design And Development Of Diaphragmless Hypersonic Shock Tunnel
(2011-03-16)The growing requirements to achieve hypersonic flights, as in the case of reentry vehicles, pose a serious challenge to the designers. This demands an understanding of the features of hypersonic flow and its effect on ... -
Residual Error Estimation And Adaptive Algorithms For Fluid Flows
(2011-03-16)The thesis deals with the development of a new residual error estimator and adaptive algorithms based on the error estimator for steady and unsteady fluid flows in a finite volume framework. The aposteriori residual error ... -
