Response of Geosynthetic Reinforced Granular Bases Under Repeated Loading
(2018-06-21)
Key factors that influence the design of paved and unpaved roads are the strength and stiffness of the pavement layers. Among other factors, the strength of pavements depends on the thickness and quality of the aggregates ...
Studies on Fracture and Fatigue Behavior of Cementitious Materials- Effects of Interfacial Transition Zone, Microcracking and Aggregate Bridging
(2018-05-14)
The microstructure of concrete contains random features over a wide range of length scales in which each length scale possess a new random composite. The influence of individual material constituents at different scales ...
Structural Safety Analysis with Alternative Uncertainty Models
(2018-07-14)
Probabilistic methods have been widely used in structural engineering to model uncertainties in loads and structural properties. The subjects of structural reliability analysis, random vibrations,
and structural system ...
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 ...
Testing of Ground Subsurface using Spectral and Multichannel Analysis of Surface Waves
(2018-06-29)
Two surface wave testing methods, namely, (i) the spectral analysis of surface waves (SASW), and (ii) the multi-channel analysis of surface waves (MASW), form non-destructive and non-intrusive techniques for predicting the ...
Analysis and Modelling of Activity-Travel Behaviour of Non-Workers from an Indian City
(2018-07-16)
Indian cities have been witnessing rapid transformation due to the synergistic effect of industrialisation, flourishing-economy, motorisation, population explosion, and
migration. The alarming increase in travel demand as ...
Site Characterization and Assessment of Various Earthquake Hazards for Micro and Micro-Level Seismic Zonations of Regions in the Peninsular India
(2018-07-28)
Past earthquakes have demonstrated that Indian sub-continent is highly vulnerable to earthquake hazards. It has been estimated that about 59 percent of the land area of the Indian subcontinent has potential risk from ...
Multi-scale Modeling of Nanoparticle Transport in Porous Media : Pore Scale to Darcy Scale
(2018-05-17)
Accurate prediction of colloid deposition rates in porous media is essential in several applications. These include natural filtration of pathogenic microorganisms such as bacteria, viruses, and protozoa, transport and ...
Grey Optimization For Uncertainty Modeling In Water Resources Systems
(2009-07-08)
In this study, methodologies for modeling grey uncertainty in water resources systems are developed, specifically for the problems in two identified areas in water resources: waste load allocation in streams and floodplain ...
Hydrologic Impacts Of Climate Change : Uncertainty Modeling
(2009-07-02)
General Circulation Models (GCMs) are tools designed to simulate time series of climate variables globally, accounting for effects of greenhouse gases in the atmosphere. They attempt to represent the physical processes in ...
