Preliminary Design Of A Pressurization System For Small Bipropellant Rocket Engines
(Aerospace Engineering, 2012-04-11)
A study was conducted on the feasibility of developing a device or system that would improve the performance of small, bipropellant rockets through pressurization of the propellants. Due to the limitations in the space ...
Evaporative Cooling Performance Of A Brazed Microporous Coating On An Aluminum Surface
(Mechanical Engineering, 2012-04-11)
The effect of an aluminum microporous coating on evaporative cooling performance was studied using distilled water as the working fluid. The aluminum microporous coating was fabricated by brazing aluminum particles to an ...
Determination Of Factors To Improve Effectiveness Of Triangulation Members For A Formula SAE Race Car Frame
(Mechanical Engineering, 2012-07-25)
This thesis suggests which factors have significant effect on the torsional and flexural stiffness of a space frame without contributing excessively to its weight. These factors are used as design variables to display ...
Multi-variable Model Of A Neural Network Based Weather Forecaster Using 2-stage Feature Selection
(Electrical Engineering, 2012-07-25)
This thesis proposes a novel approach for designing a neural network based forecaster that predicts more than one variable at a time. A second order two stage neural network training algorithm is used that employs orthogonal ...
A Study Of The Viscous Interaction Between The Solar Wind And Earth's Magnetosphere Using An MHD Simulation
(Physics, 2012-07-25)
The solar wind interacts with Earth's magnetosphere largely through magnetic reconnection and a “viscous-like” interaction that is not fully understood. The ionospheric cross-polar cap potential (ΦPC) component due to ...
Second Order Training Algorithms For Radial Basis Function Neural Networks
(Electrical Engineering, 2012-04-11)
A systematic two step batch approach for constructing and training of Radial basis function (RBF) neural networks is presented. Unlike other RBF learning algorithms, the proposed paradigm uses <italic>optimal learning ...
Stable Reference Trajectory Modification For Handling Actuator Failure In Control Systems
(Aerospace Engineering, 2012-04-11)
The issue of rapidly reconfiguring the reference trajectory under unanticipated actuator failures in order to regain lost performance or aircraft handling qualities is explored. The failures detected in real-time are ...
Bioanalytical LC-MS: Streamlined Sampled Preparation And Novel Ambient Ionization Techniques
(Chemistry & Biochemistry, 2012-07-25)
Bioanalysis has gained importance in the scientific at an exponential rate. The focus of these works attempt to seek new approaches towards faster and more efficient bioanalysis that require little to no sample preparation. ...
Investigation Of Co-pyrolysis Between Sargassum Macroalgae And Polystyrene
(Civil & Environmental Engineering, 2012-07-25)
Biomass is one source of renewable energy which helps minimize greenhouse gas (GHG) emissions, specifically carbon dioxide (CO2), since biomass utilizes CO2 via photosynthesis. Various conversion processes are applied to ...
Proximity Of Cancer Cases To Airports Within The State Of Texas
(Environmental & Earth Science, 2012-07-25)
Determining whether the incidence of cancer may be associated with pollutants emitted from airports is important in order to better plan cities to reduce such incidences. This research aims to answer the following questions: ...
