An Integrated Choice and Latent Variable Framework to Incorporate the Influence of Travel Time Variability on Truck Route Choice
Route choice models (or path choice models) are useful for quantifying travellers’ preferences for or sensitivity to route attributes, predicting network-level traffic flows, examining the influence of information provided ...
Experimental studies on the fracture and fatigue failure processes under direct tension in quasi-brittle materials - Graphite and Concrete
Abstract
Fatigue phenomenon is a gradual, permanent, micro structural change that takes place
in a material due to the application of repeated loading. In the case of quasi-brittle
materials like graphite and concrete, ...
Factors Influencing Contaminant Transport in Vadose Zone of Near Surface Radioactive Waste Disposal Facility
Radioactive waste is generally classified as low and intermediate level waste
(LILW) and high-level waste (HLW), based on their level of radioactivity and the time
taken for decay. The low and intermediate level ...
Studies on the Mechanisms of Fracture, Evolution of Microcracks and Size Effect in Concrete through Acoustic Emission Analysis
The mechanics of fracture evolution in heterogeneous material like concrete is a distinct and complex phenomenon and still stands as an open problem after decades of research. A cluster of multi-scale cracks ahead of the ...
Rheological Studies on Slow Flow in Dense Granular Ensembles
An experimental study on the rheology and kinematics of dense granular materials is presented in this thesis in the slow flow regime. In this study, we employ an often used experimental set up of the cylindrical Couette ...
Structural dynamic testing for seismic response simulation and time variant reliability estimation
The research work reported in this thesis addresses a few problems which arise in the context of experimental dynamic testing of engineering structures under earthquake loads. Firstly, we consider the problem of characterizing ...
Interference Effect of Closely Spaced Square Footings on Geocell Reinforced Sand and Clay Beds: Experimental and Numerical Studies
With rapid growth of construction rate and lack of suitable land sites for construction, placing building foundations close to each other and on soft-grounds is inevitable. When the foundations are placed close enough on ...
Hyperspectral Remote Sensing for Land Cover Classification and Chlorophyll Content Estimation using Advanced Machine Learning Techniques
In the recent years, remote sensing data or images have great potential for continuous spatial and temporal monitoring of Earth surface features. In case of optical remote sensing, hyperspectral (HS) data contains abundant ...
Modeling the Dependence Structure of Hydroclimatic Extremes
Analysis of extremes in a complex interacting hydroclimatic system is challenging due to rarity of events, small sample size, poor state of data or missing data, lack of statistical tools for analyzing observed changes and ...
Hydrologic Inference: A Complex Systems Approach
The aim of this thesis is to understand linkages between hydrologic processes and patterns from the perspective of a complex system. In hydrologic systems, there exist interactions of hydrologic components among themselves ...
