Precombustion Removal of Hazardous Air Pollutant Precursors
(Virginia Tech, 1997-12-16)
The 1990 Clean Air Act Amendment (CAAA) contains provisions that will establish new emission standards for 190 potentially hazardous air pollutant precursors (HAPPs). Studies have suggested that many of these HAPPs have ...
Analysis of Freeway Weaving Areas Using Corridor Simulator and Highway Capacity Manual
(Virginia Tech, 1997-12-01)
Weaving is defined as the crossing of two or more traffic streams traveling in the same direction along a significant length of the highway without the aid of traffic control devices . The traditional methods used for ...
A Simulation Analysis of Bivariate Availability Models
(Virginia Tech, 2000-07-24)
Equipment behavior is often discussed in terms of age and use. For example, an automobile is frequently referred to 3 years old with 30,000 miles. Bivariate failure modeling provides a framework for studying system ...
Systems Integration, Modeling, and Validation of a Fuel Cell Hybrid Electric Vehicle
(Virginia Tech, 2000-05-04)
The goals of the research documented in this thesis were the design, construction, modeling, and validation of a fuel cell hybrid electric vehicle based a conversion of a five-passenger production sedan. Over 60 engineering ...
The Effects of Ageing Error on Stock Assessment for Weakfish Cynoscion regalis
(Virginia Tech, 2013-06-12)
Inherent uncertainties in the stock assessment for weakfish have precluded accurate and consistent advice concerning the management of commercial and recreational fisheries. Error within ageing techniques, used to assess ...
Simulation of Chinese Sorghum Imports from a New Perspective: U.S. and Global Impacts
(Virginia Tech, 2017-06-15)
This thesis aims to analyze the impacts on U.S. and global sorghum trade, and whether China will continue importing sorghum from the global sorghum market for feed use, if the Chinese government cancels its corn price ...
Spacecraft-ns3: Spacecraft Discrete-Event Network Simulation
(Virginia Tech, 2020-06-24)
As near-Earth space becomes more populated with large constellations of satellites and research into spacecraft autonomy and disaggregation becomes more prevalent, it will be increasingly important to design effective ...
Multi-GPU Load Balancing for Simulation and Rendering
(Virginia Tech, 2011-06-24)
GPU computing can significantly improve performance by taking advantage of massive parallelism of GPUs for data parallel applications. Computation in visualization applications is suitable for parallelization on the GPU, ...
Simulating the Spread of Malaria: A Cellular Automaton Based Mathematical Model & A Prototype Software Implementation
(Virginia Tech, 2007-02-05)
Every year three million deaths are attributed to malaria, of which one-third are of children. Malaria is a vector-borne disease, where a mosquito acts as the vector that transmits the disease. In the last few years, ...
On the Simulation of an All Electric Ship Powertrain Utilizing a Surface Piercing Propeller Via a Modular Main Propulsion Plant Model
(Virginia Tech, 2011-05-23)
A modular simulation model of a marine powertrain consisting of a prime mover, propeller shaft, propulsor, and control system was developed, tested, and used to demonstrate the ability to analyze the marine powertrain ...
