A Macroscopic Validation Of The Evacuation Simulation Prediction Tool On Highway Travel Times, Kay Fortinberry Borglum Apr 2007

A Macroscopic Validation Of The Evacuation Simulation Prediction Tool On Highway Travel Times, Kay Fortinberry Borglum

Master's Theses - Daytona Beach

The purpose of this applied research study was to test the sensitivity of the Evacuation Simulation Prediction (ESP) tool in predicting travel time during high volume traffic periods. The discrete event-based simulation tool was designed to aid local evacuation planning contingencies. Research of the Florida Department of Transportation traffic count data demonstrated parallel trends in rush hour volume versus hurricane evacuation volume. A model validation was designed to test if the model closely predicted high volume travel on a major interstate. For this macroscopic sensitivity test, volume, travel time and speed were collected to examine the baseline predictability under crash …


Simulated Analysis Of Drought’S Impact On Different Cow-Calf Production Systems, Matthew C. Stockton, Roger K. Wilson Feb 2007

Simulated Analysis Of Drought’S Impact On Different Cow-Calf Production Systems, Matthew C. Stockton, Roger K. Wilson

Department of Agricultural Economics: Presentations, Working Papers, and Gray Literature

Five representative, firm-level, stochastic simulation models were constructed using historical production cost, cattle prices, weather information and scientifically collected production data from the Gudmundsen Sandhills Laboratory operated by the University of Nebraska. The five hundred iterative results indicate the inclusion of crop residual grazing is a viable drought mitigation tool.


Numerical Simulation Of Temperature Field And Thermal Stress Field Of Work Roll During Hot Strip Rolling, Chang-Sheng Li, Hai-Liang Yu, Guan-Yu Deng, Xiang-Hua Liu, Guo-Dong Wang Jan 2007

Numerical Simulation Of Temperature Field And Thermal Stress Field Of Work Roll During Hot Strip Rolling, Chang-Sheng Li, Hai-Liang Yu, Guan-Yu Deng, Xiang-Hua Liu, Guo-Dong Wang

Faculty of Engineering and Information Sciences - Papers: Part A

Based on the thermal conduction equations, the three-dimensional (3D) temperature field of a work roll was investigated using finite element method (FEM). The variations in the surface temperature of the work roll during hot strip rolling were described, and the thermal stress field of the work roll was also analyzed. The results showed that the highest roll surface temperature is 593 °C, and the difference between the minimum and maximum values of thermal stress of the work roll surface is 145. 7 MPa. Furthermore, the results of this analysis indicate that temperature and thermal stress are useful parameters for the …


Geant4 Physics Processes For Microdosimetry Simulation: Design Foundation And Implementation Of The First Set Of Models, S. Chauvie, Z. Francis, S. Guatelli, S. Incerti, B. Mascialino, P. Moretto, P. Nieminen, Maria G. Pia Jan 2007

Geant4 Physics Processes For Microdosimetry Simulation: Design Foundation And Implementation Of The First Set Of Models, S. Chauvie, Z. Francis, S. Guatelli, S. Incerti, B. Mascialino, P. Moretto, P. Nieminen, Maria G. Pia

Faculty of Health and Behavioural Sciences - Papers (Archive)

New physical processes specific for microdosimetry simulation are under development in the Geant4 Low Energy Electromagnetic package. The first set of models implemented for this purpose cover the interactions of electrons, protons and light ions in liquid water; they address a physics domain relevant to the simulation of radiation effects in biological systems, where water represents an important component. The design developed for effectively handling particle interactions down to a low energy scale and the physics models implemented in the first public release of the software are described.
