“Narco-Deforestation” in Central American Protected Areas: Developing A Spatiotemporal Proxy Database for Drug-Trafficking Activities from Media Reporting

Creator:: Cameron, Olivia Z.
Abstract:: On a global scale, illicit economies have dramatic impacts on the physical environment. Cocaine trafficking has been recognized as a major driver of deforestation inside Central American protected areas. A key problem in studying and managing the environmental impacts of illicit economic activity is the difficulty in obtaining reliable data....

A Comprehensive Methodology for Measuring the Performance of Transit Networks

Creator:: Rahanjam, Mehrdad
Abstract:: The performance of transit networks must be measured on a regular basis to understand how well these complex systems fulfill their intended purpose and to identify potential opportunities for improvement. Measuring transit network performance is only achievable by defining a specific set of transit network performance indicators (TNPIs). Different schemes...

A Fully Integrated Bio-potential Low-noise Amplifier Utilizing Capacitor Multipliers

Creator:: Yong, OnnLim
Abstract:: In any biomedical signal acquisition system, a front-end amplifier is needed to amplify low amplitude bio-signals while filtering out any unwanted low-frequency artifacts. The design of low frequency poles within the sub-Hz range implies very large time-constants which goes against system integrability. In recent years, the pseudo resistor has been...

A Metaheuristic Approach for Facilities Location with Balanced Allocation of Customers

Creator:: Nippaya, Dheeraporn
Abstract:: Organizations are constantly looking for innovative strategies to face more stringent competitive environments and the ever increasing market globalization. An alternative these organizations can pursue to respond to these challenges is to optimize their supply chain network (SCN). Important considerations when optimizing a SCN involve determining locations for plants and...

A Text-based Simulation Framework for the Automated Simulation and Analysis of Manufacturing Assembly Systems

Creator:: Fields, Benjamin G.
Abstract:: The rapid advancement of manufacturing has led to the creation of a myriad of technologies that facilitate the analysis and simulation of manufacturing processes. These technologies have become a pivotal component in maintaining and improving processes in today’s complex manufacturing environments. Discrete Event Simulation (DES) is one such technology that...

A wireless sensor network approach for estimating individual task time

Creator:: Atichat, Tanawat
Abstract:: Most existing methods for generating individual task time estimates in production systems where jobs move through various manually operated workstations remain tedious and time consuming. For existing systems, average task times may vary considerably from prior estimates causing system inefficiencies, poor scheduling and poor planning decisions. Accurate and up-to-date estimates...

An Econometric Analysis of the Impact of Climate Change on Forest Land Value and Broad Land-use Change

Creator:: Mihiar, Christopher
Abstract:: Climate change affects the choice of land-use not only through its direct effect on the productive potential of land, but also through human actions that alter the landscape. In this dissertation, I estimate current climate's effect on the economic net returns to alternative land-use systems in the United States. Then...

An Empirical Analysis of Climate and Risk on Rural Productive Lands

Creator:: Finer, Cassie R.
Abstract:: Efficient and effective climate policies require cost estimates supported by empirical analysis at multiple spatial scales. Fine-scale spatial analysis of climate impacts for rural land markets represents a gap in the current climate change economics literature. In this dissertation I estimate relationships between climate, risk and parcel-level land values for...

An Examination of Factors Controlling the Activity of Ammonia- and Nitrite-oxidizers in Diverse Soils

Creator:: Giguere, Andrew T.
Abstract:: Nitrification is a critical step in the global nitrogen cycle involving the biological oxidation of ammonia (NH₃) to nitrite (NO₂⁻ ) and then to nitrate (NO₃⁻). The first step in nitrification is carried out by NH₃-oxidizing bacteria (AOB) and archaea (AOA), and the second by NO₂⁻-oxidizing bacteria (NOB). In addition...

An Ising-like model to predict dielectric properties of the relaxor ferroelectric solid solution BaTiO3 - Bi(Zn1/2Ti1/2)O3, An Ising-like model to predict dielectric properties of the relaxor ferroelectric solid solution BaTiO₃ − Bi(Zn₁/₂Ti₁/₂)O₃

Creator:: Jackson, Dennis L.
Abstract:: We developed a model to investigate the dielectric properties of the BaTiO₃ − Bi(Zn₁/₂Ti₁/₂)O₃ (BT-BZT) solid solution, which is a relaxor ferroelectric and exhibits long range disorder. The model uses ab initio methods to determine all polarization states for every atomic configuration of 2 x 2 x 2 supercells of...
