Algorithms For Constructing Vehicle Trajectories In Urban Networks Using Inertial Sensors Data From Mobile Devices, Umana Ahmed
Algorithms For Constructing Vehicle Trajectories In Urban Networks Using Inertial Sensors Data From Mobile Devices, Umana Ahmed
Computational Modeling & Simulation Engineering Theses & Dissertations
Vehicle trajectories are an important source of information for estimating traffic flow characteristics. Lately, several studies have focused on identifying a vehicle’s trajectory in traffic network using data from mobile devices. However, these studies predominantly employed GPS coordinate information for tracking a vehicle’s speed and position in the transportation network. Considering the known limitations of GPS, such as, connectivity issues at urban canyons and underpasses, low precision of localization, high power consumption of device while GPS is in use, this research focuses on developing alternate methods for identifying a vehicle’s trajectory at an intersection and at a urban grid network …
High Resolution Spectra Of Carbon Monoxide, Propane And Ammonia For Atmospheric Remote Sensing, Christopher Andrew Beale
High Resolution Spectra Of Carbon Monoxide, Propane And Ammonia For Atmospheric Remote Sensing, Christopher Andrew Beale
OES Theses and Dissertations
Spectroscopy is a critical tool for analyzing atmospheric data. Identification of atmospheric parameters such as temperature, pressure and the existence and concentrations of constituent gases via remote sensing techniques are only possible with spectroscopic data. These form the basis of model atmospheres which may be compared to observations to determine such parameters. To this end, this dissertation explores the spectroscopy of three molecules: ammonia, propane and carbon monoxide.
Infrared spectra have been recorded for ammonia in the region 2400-9000 cm-1. These spectra were recorded at elevated temperatures (from 293-973 K) using a Fourier Transform Spectrometer (FTS). Comparison between …
Diffusion Of Renewable Energy Policies, Khatera Alizada
Diffusion Of Renewable Energy Policies, Khatera Alizada
Graduate Program in International Studies Theses & Dissertations
This study examines the global diffusion of renewable energy policies: feed-in tariffs (FIT) and renewable portfolio standards (RPS). Existing studies of policy diffusion have failed to differentiate between four possible mechanisms of policy diffusion: emulation, suasion, learning and competition. To test these competing explanations, the study uses a mixed-method research design that combines statistical analysis of time-series cross-sectional data with an agent-based model of diffusion processes. The findings of the statistical analysis show strong support for the suasion (European Union Membership, Clean Development Mechanisms) and emulation mechanisms (cultural similarity or common language) in the diffusion of FIT. In the diffusion …
