Evaluation Frameworks for Informed Multi-Site Multi-Variate Hydrological Assessment
The process of choosing a suitable hydrological model, calibrating it, and evaluating its performance poses intricate challenges for a modeler. The process of model selection is frequently influenced by the modeller's ...
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 ...
Aggregate and Disaggregate-level Models of Public Transit Ridership in Bengaluru, India
Ridership forecasting models are valuable tools for public transit agencies to assess and
quantify the possible impacts of their operational strategies and service improvements on transit
demand and revenue. Although ...
Exploring Hydrological Processes, Modeling Decisions, and Deep Learning for Improved Hydrologic Assessment
Hydrological modeling is complicated by the intricate challenges and uncertainties associated with understanding hydrological processes. This thesis aims at answering some of the key research questions related to ...
Investigating and Modelling the Microscopic Pedestrian Behavioral Dynamics in Mass Religious Gatherings
Pedestrian models that can realistically reproduce observed pedestrian movement dynamics are crucial in facility planning and pre-event planning of crowded situations. Despite the elaborate arrangements, crowd disasters ...
Effects of 3d Morphological Characteristics of Sand on Multi-scale Intergranular and Sand-geosynthetic Interactions
To understand the process of mobilization of shear strength in sands and sand-geosynthetic interfaces at a fundamental level, it is essential to precisely characterize the size and shape of the grains and the shear-induced ...
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 ...
Simulation of complex plastic flows in metal sliding and cutting
Metal manufacturing encompasses a broad range of mechanical transformation processes that shape native metal into useful forms. These processes generally involve the interaction of a hard tool with a specimen / workpiece, ...
Comparison of Additive and Multiplicative Kinematics in Large Deformation Plasticity
The most widely used plasticity model in commercial finite element analysis software packages
is the additive plasticity model. One of the more well-known alternatives to additive
plasticity is multiplicative plasticity. ...
