UNLV Theses, Dissertations, Professional Papers, and Capstones
In this thesis we study the travel time problem based on the known traffic density model. Using the conservation law, we model the travel time function by a boundary value problem of a non homogeneous linear hyperbolic equation. The equation is transformed into an initial value hyperbolic equation, and the well-posedness of the problem is discussed. The mathematical analysis for both density and travel problems are given. We also derive the analytic solutions for several special cases of traffic density. Numerical schemes are proposed for solving for travel time problem. Several numerical examples are presented and error analysis on the …

Congressional Preferences And The Advancement Of American Nuclear Waste Policy, Rhoel Gonzales Ternate
UNLV Theses, Dissertations, Professional Papers, and Capstones
The problem of nuclear waste disposal has existed since the time of the Manhattan Project in World War II. Although there exist a number of technological hurdles, the main cause that has consistently plagued a solution to nuclear waste has been the politics behind it. This thesis attempts to add to the political literature behind nuclear waste disposal by examining the nuclear waste disposal preferences of members of the United States House and Senate. It then compares and contrasts those preferences with a report by President Obama's Blue Ribbon Commission on America's Nuclear Future. The hope was to determine if …

Traffic Modeling In Lagrangian Coordinates Using Smartphone Apps, Sergio Contreras
UNLV Theses, Dissertations, Professional Papers, and Capstones
Traditionally, one of the ways traffic flow has been studied is by using the kinematic wave model. This model is derived in the Eulerian framework by using conservation of the number of vehicles. Recently, the kinematic wave model has been transformed into Lagrangian coordinates. In this framework, the independent variables are unique
vehicles and time. The detailed change in framework, and the properties of the model in the changed framework are reviewed. Numerical results from different traffic cases are explained. Since vehicle trajectory data can be easily collected from smartphones,
a smartphone application is developed for this purpose. This data …
