Micromechanical modeling of fracture and fatigue behavior of cementitious composites
The ubiquitous use of concrete as a construction material in the civil engineering industry demands a thorough understanding of its failure process under different types of loading. The composite nature of cementitious ... -
Micromechanics of Wedge and Cone Indentation of Metallic Specimens with Subsurface Voids
Near-surface voids and pores occur in metal parts manufactured by processes as diverse as casting, powder metallurgy, and additive manufacturing. These pores range in size from a few microns to a few mm, depending on the ... -
Modeling and Analysis of Water Distribution Systems
(2018-01-09)In most of the urban cities of developing countries piped water supply is intermittent and they receive water on alternate days for about few hours. The Unaccounted For Water (UFW) in these cities is very high due to aged ... -
Modeling Of Contaminant Transport Through Soils And Landfill Liners
(2013-04-26)Accurate modeling of contaminant transport and sorption processes in the soil and landfill liners is a prerequisite for realistic model simulations of contaminant fate and transport in the environment. These studies are ... -
Modeling Salinity Impact on Ground Water Irrigated Turmeric Crop
(2018-04-18)Soils in irrigated fields are impacted by irrigation water quality. Salts in the irrigation water may accumulate in the soil depending on amount of leaching, the quality of water and type of ions present. Salinity is an ... -
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 ... -
Modelling Evapotranspiration from Satellite Data using semi-empirical Models : Applications to the Indian Subcontinent
(2018-05-22)The major aim of this work is to develop a framework for the estimation of Evapotranspiration (ET) over the Indian landmass using remote sensing (RS) datasets in a repeated and consistent manner with improved spatial ... -
Modelling Hydrology of Upper Cauvery Basin Considering Changes in Climate and Landuse/Landcover
In the recent times, changes are noted in hydrological processes (e.g., surface runoff, lateral flow, infiltration, return flow, evapotranspiration, soil moisture and streamflow) in different river basins of the world due ... -
Modelling Of Single And Multiple Recharge Wells In Layered Aquifers
(2009-05-06)Artificial recharge and rainwater harvesting methods are being applied for mitigating effects of groundwater depletions in severe over-drafting urban and rural situations. When the aquifer to be recharged is situated at ... -
Monitoring and Control of Intermittent Water Distribution Network
Millions of people in low and middle-income countries worldwide receive water only for a small fraction of the time in a day through piped networks. Even though the percentage of the world’s population with access to piped ... -
Monte Carlo Simulation Based Response Estimation and Model Updating in Nonlinear Random Vibrations
(2018-02-22)The study of randomly excited nonlinear dynamical systems forms the focus of this thesis. We discuss two classes of problems: first, the characterization of nonlinear random response of the system before it comes into ... -
Monte Carlo Simulations with Variance Reduction for Structural Reliability Modeling, Updating and Testing
(2018-04-24)Monte Carlo simulation techniques have emerged as widely accepted computing tools in tackling many problems in modern structural mechanics. Apart from developments in computational hardware, which have undoubtedly made ... -
Morphological Perspectives of Sand Liquefaction and its Mitigation
Liquefaction of soils under seismic conditions has profound implications for infrastructure resilience in earthquake-prone regions. Saturated loose cohesionless granular soils have the tendency to readily lose grain contacts ... -
Multi-level Partitioning Algorithms & Reliability Analysis for Transit Networks
Public transit systems are an indispensable part of any metropolitan city. Its success depends on many factors, chief among which is the ease with which users can query for optimal journeys using mobile apps. Conventional ... -
A multi-physics-based modelling approach to predict mechanical and thermo-mechanical behaviour of cementitious composite in a multi-scale framework
Concrete is a heterogeneous material whose constituents (e.g., cement paste, aggregate etc.) range from a characteristic length-scale dimension of a nanometre to a metre. Owing to the heterogeneity of concrete and the ... -
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 ... -
Multi-vehicle anticipation-based models for describing driver behaviour in heterogeneous and disorderly traffic conditions
Driver behaviour models are widely used in the traffic engineering literature and practice. They are used for understanding drivers’ manoeuvring decisions in traffic streams. They also form the building blocks of microscopic ... -
Multiple Discrete-Continuous Choice Models with Flexible Specification of Constraints, Utility Forms, and Stochastic Distributions: Applications in Travel Behavior Research
Econometric choice models have been widely used in travel behaviour research to understand human activities, time-use, mobility choices, consumption, and related preferences. Most research in this area had focused on ... -
