Operation Optimization And Water Quality Simulation Of Potable Water Distribution System, Xiongfei Xie
Operation Optimization And Water Quality Simulation Of Potable Water Distribution System, Xiongfei Xie
USF Tampa Graduate Theses and Dissertations
A potable water distribution system (WDS) consists of pipes, pumps, valves, storage tanks, control and supporting components. Traditionally, it has two basic functions. First, provides end users with potable water at sufficient pressures and good water quality. Second, provides sufficient pressure and flow for fire fighting. Currently, potable water is still the least expensive material for fire fighting. To accomplish these two goals, water utilities have to consider the integrity and security of the water network. As a result, this research selected three research topics that are closely related to the daily operation of water utilities and water quality simulation. …
Understanding Operating Speed Variation Of Multilane Highways With New Access Density Definition And Simulation Outputs, Bing Huang
USF Tampa Graduate Theses and Dissertations
Traffic speed is generally considered a core issue in roadway safety. Previous studies show that faster travel is not necessarily associated with an increased risk of being involved in a crash. When vehicles travel at the same speed in the same direction (even high speeds, as on interstates), they are not passing one another and cannot collide as long as they maintain the same speed. Conversely, the frequency of crashes increases when vehicles are traveling at different rates of speed. There is no doubt that the greater speed variation is, the greater the number of interactions among vehicles is, resulting …
