Uncertainty Analysis of Microwave Based Rainfall Estimates over a River Basin Using TRMM Orbital Data Products
(2018-01-11)Error characteristics associated with satellite-derived precipitation products are important for atmospheric and hydrological model data assimilation, forecasting, and climate diagnostic applications. This information also ... -
Uncertainty Based Damage Identification and Prediction of Long-Time Deformation in Concrete Structures
(2018-02-20)Uncertainties are present in the inverse analysis of damage identification with respect to the given measurements, mainly the modelling uncertainties and the measurement uncertainties. Modelling uncertainties occur due to ... -
Uncertainty Modeling For River Water Quality Control
(2010-08-30)Waste Load Allocation (WLA) in rivers refers to the determination of required pollutant fractional removal levels at a set of point sources of pollution to ensure that water quality standards are maintained throughout the ... -
Uncertainty Quantification in Flow and Flow Induced Structural Response
(2018-07-23)Response of flexible structures — such as cable-supported bridges and aircraft wings — is associated with a number of uncertainties in structural and flow parameters. This thesis is aimed at efficient uncertainty quantification ... -
Understanding Catchment Scale Processes: Hydrological Modelling and Information-Theoretic Approaches
Catchments are complex environmental systems, and they serve as the fundamental units for hydrological classification. They are self-organizing systems whose form, drainage network, ground and channel slopes, channel ... -
Understanding Strain Rate Response of Geomaterials through Orthogonal Cutting Experiments
Cutting is a complex, large deformation process used for the removal of material during various engineering operations. In geomaterials, such as soils and rocks, the mechanism of cutting is encountered during operations ... -
Unsteady two-Dimensional flow field behind perforated plates on a flat surface
The flow over bluff bodies with separation is one of the oldest in fluid mechanics. The separated flows would be considered to have local streamline curvature; such flows are particularly of interest in engineering due to ... -
Upper Bound Finite Element Limit Analysis for Problems of Reinforced Earth, Unsupported Tunnels and a Group of Anchors
(2017-11-27)This thesis presents the implementation of the upper bound limit analysis in combination with finite elements and linear optimization for solving different stability problems in geomechanics under plane strain conditions. ... -
VENTURI STUDIES WITH WATER ON CAVITATIOK INCEPTION CAVITY CHARACTERISTICS AND CAVITATION EROSION BEHIND BLUFF BODIES
Cavitation is defined as the formation, growth and collapse of vapour or gas? and vapour?filled bubbles in a liquid subjected to reduced pressures (of the order of the vapour pressure of the liquid) at constant ambient ... -
Vibration Analysis Of Structures Built Up Of Randomly Inhomogeneous Curved And Straight Beams Using Stochastic Dynamic Stiffness Matrix Method
(Indian Institute of Science, 2006-07-19)Uncertainties in load and system properties play a significant role in reliability analysis of vibrating structural systems. The subject of random vibrations has evolved over the last few decades to deal with uncertainties ... -
Vibration Testing of Structures under Random Support Excitations
(2018-07-30)Vibration testing of structures constitutes a crucial step in design and commissioning of engineering structures. The focus here is on simulating field conditions in a laboratory so that detailed investigations of the ... -
Virtual Element Methods for Phase Field Fracture: Mesh Transitions, Composite Damage, and Stabilization-Free Formulations
Accurate simulation of crack propagation requires discretization methods that combine geometric flexibility with computational efficiency. Although the finite element method (FEM) and its variants remain the widely used ... -
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 ... -
Weakly cemented granular materials: study at multiple length scales
Cemented granular systems are encountered at various scales in nature and artificially. We present an experimental study carried out on the structure and mechanical behaviour of weakly cemented granular materials. We study ...
