Integrated transportation and energy activity-based model
… This thesis develops the framework for an urban model that serves as a decision support tool to inform sustainable policies and investments. The model discussed integrates the modeling of land use, transportation, and energy consumption by micro-simulating the behavior of households and firms in …

Developing an Activity-Based Model for City-Scale Cross-Sectoral Energy and Carbon Emissions Management
Emerging working patterns (such as home-based and flexible working) are becoming increasingly prevalent worldwide, reshaping how urban residents allocate their time and interact with the built environment. These structural shifts are changing the spatial and temporal distribution of energy demand …

Developing advanced econometric frameworks for modeling multidimensional choices : an application to integrated land-use activity based model framework
… to contribute to the growing literature on the activity-based framework by focusing on the modeling of choices that are influenced by land-use and travel environment attributes. An accurate characterization of activity-travel patterns requires explicit consideration of the land-use and travel …

Calibrating activity-based travel demand model system via microsimulation
This thesis addresses the problem of calibrating activity-based travel demand model systems. After estimation, it is common practice to use aggregate measurements to calibrate the estimated model system's parameters. However, calibration of activity-based model systems has received much less …

Inferring user location from time series of social media activity
… their posts, but the precision of existing time-based location predictors is limited to discrimination among time zones. In this thesis, we formulate a general time-based geolocation algorithm that has greater precision, using knowledge of a social media user's real world activities derived from …

Numerical tools for rate-cost-quality analysis of laser-based additive manufacturing
… and cost for AM processes, we present a physics-based rate and cost estimator for scanning laser based AM. The model takes a mesh representation of the part design as input, and uses a parametrized model of the rate-limiting physics of the build process to estimate the part-specific build time …

Analysis of Social Equity in Transportation in Washington DC Region Considering Sea Level Rise Using Advanced Travel Demand Models
… the use of a large-scale, high-fidelity agent-based, activity-based travel demand model to produce travel times to employment centers. This travel time is used as a proxy to access to opportunities. The results are visualized in a GIS heatmap. The model is applied to the Metropolitan Washington …

A mathematical model of a high sulphate wastewater, anaerobic treatment system
… wastewaters, originating from industrial activity or from the biological oxidation of sulphide ores (acid mine drainage), cannot be discharged into the environment untreated. Apart from the high sulphate levels, these waters may be very acidic and have high dissolved heavy metal …

A needs-based approach to activity generation for travel demand analysis/
This thesis develops a needs-based framework for behavioral enhancement of conventional activity-based travel demand models. Operational activity-based models specify activity generation models based on empirical considerations which are weakly founded in a behavioral theory. This thesis aims to …

An Examination of γ-valerolactone Ring Opening and Decarboxylation in Multiphase System and Over Various Solid Acid Catalysts
… separate PEA from GVL. A two-parameter Margules model was further applied to regress the activity coefficient, and it successfully described the phase distribution at any given compositions in the biphasic system. Furthermore, an activity-based model was proposed to simulate the reaction in the …

Multiphase, Multicomponent Systems: Divalent Ionic Surfactant Phases and Single-Particle Engineering of Protein and Polymer Glasses
… encapsulated in a biodegradable polymer), and as model systems with which to study the materials and principles that govern particle formation. The assumptions of the Epstein-Plesset model, which predicts the rate of droplet dissolution, are examined in the context of the micropipette technique. A …
