Modeling Movement Of Criminals Through Burglary Scenes, Veronica L. Herrmann Jan 2019

Modeling Movement Of Criminals Through Burglary Scenes, Veronica L. Herrmann

Graduate Theses, Dissertations, and Problem Reports

Physical evidence plays a large role in the criminal justice system and in crime scene reconstruction. The purpose of evidence is to assist in connecting a person or persons to an incidence, which helps crime scene investigators in reconstructing the events that occurred at the crime scene. This concept is mainly based off Locard's Exchange Principle, which states that there is always an association between an offender and evidence. However, without patent evidence to lead the investigators to a possible route at the scene, determining the movements taken during the commission at a scene is needed.

Engineers have used simulations …


A Framework For Energy Optimization Of Small, Two-Stroke, Natural Gas Engines For Combined Heat And Power Applications, Mahdi Darzi Jan 2019

A Framework For Energy Optimization Of Small, Two-Stroke, Natural Gas Engines For Combined Heat And Power Applications, Mahdi Darzi

Graduate Theses, Dissertations, and Problem Reports

This research was focused on the development of a framework for the energy optimization a natural gas engine for small combined heat and power (CHP) applications operating with low-pressure natural gas (NG) available at homes. The required targets of the ARPA-E GENSETS program for 1 kW electric power generation and previous GENSETS simulation at West Virginia University, suggested a design space for the engine which is currently dominated by simple two-stroke designs. Hence this research focused on screening, modeling, and experimentally evaluation of cost-effective technologies to achieve a system design that maximized thermal efficiency and utilization factor, while reducing emissions. …


Low Power Voltage Reference Cells For Sensing Applications, Kody Ray Tucker Jan 2019

Low Power Voltage Reference Cells For Sensing Applications, Kody Ray Tucker

Graduate Theses, Dissertations, and Problem Reports

Two low-power voltage reference cells for a system on-chip design are presented in this report. Both cells utilize a combination of standard transistors to produce an output voltage near 1 volt. Choosing the appropriate design procedures can aid in minimizing the temperature coefficient (TC) of the output reference voltage coming out of the cell. One circuit, covered first, is currently being fabricated on a standard 0.5 µm chip complementary metal oxide semiconductor (CMOS) process, while the other is still in the designing stage. The first one has a TC of 86 ppm/◦C with a reference voltage of 1.10 V while …
