Effect Of Different Traffic Signal Control Plans On Simulation Of Hurricane Evacuation Traffic, Divya Kolasani Jan 2019

Effect Of Different Traffic Signal Control Plans On Simulation Of Hurricane Evacuation Traffic, Divya Kolasani

LSU Master's Theses

The majority of hurricane evacuation modeling studies concentrate on evacuation traffic on freeways with relatively little attention being given to traffic on arterials. This study is focused on evaluating the evacuation efficiency of a network under different traffic signal settings on arterials using microscopic simulation. This is achieved by changing the traffic signal settings from existing signal timing plans to flashing yellow on major evacuation routes and flashing red on cross streets, for a given evacuation order. Time-dependent origin-destination matrices for hurricane evacuation up to 72 hours away from landfall for No Evacuation order, as well as a Voluntary/Mandatory Evacuation …


Design And Optimization Of An Ionizing-Radiation-Free Dental Imaging Scheme By Near Infrared Fluorescence, Thomas Hartzler Jan 2019

Design And Optimization Of An Ionizing-Radiation-Free Dental Imaging Scheme By Near Infrared Fluorescence, Thomas Hartzler

LSU Master's Theses

There is a global need for access to oral health care. Proper oral health care is necessary for physiological and psychological health, as well as social and economic issues. Major oral diseases that must be screened include caries, cracked teeth, and impacted molars. These diseases are screened and diagnosed using a variety of medical imaging methods, computed tomography (CT) X-ray being the most popular and efficient method. The challenges in screening with X-ray technology include financial and time cost as well as health risk, including radiation exposure induced cancer (REIC). This thesis summarizes research to explore the possibility of overcoming …
