Blowoff characteristics of partially premixed flames of prevaporized blends of biofuels and petroleum fuels
(2017-12-15)
The laminar partially premixed flames of prevaporized Jet A, canola methyl ester (CME), palm methyl ester (PME), soy methyl ester (SME), and blend flames of Jet A and CME-PME-SME were studied over a range of equivalence ...
Design and Performance Evaluation of a Retractable Wingtip Vortex Reduction Device
(2019-12)
As an airfoil achieves lift, the pressure differential at the wingtips trigger the roll up of fluid which results in swirling wakes. This wake is characterized by the presence of strong rotating cylindrical vortices that ...

Robust Adaptive Control Laws for Tilt-Rotor Quadcopters Subject to User-Defined Constraints
(2019-05-10)
This thesis focuses on Model Reference Adaptive Control (MRAC) and its application to a tilt-rotor quadcopter. After formulating two standard MRAC approaches, this thesis proposes a robust model reference adaptive control ...
Additive Manufacturing of HDPE Using Selective Laser Sintering
(2019-05-10)
Selective Laser Sintering (SLS) is an additive manufacturing technique that bonds solid powder particles into complex 3-Dimensional (3D) shapes. These objects are constructed by repeatedly sintering or fusing layers of ...
Virtual Measurement of Valve Performance and its Application in Energy Efficiency Improvements
(2018-12)
For heating, ventilation, and air-conditioning engineers, the measurement of system performance is a vital step in ensuring that the system in use is functioning at its optimal functionality. The measurement of water flow ...
Preliminary Design of Robust Adaptive Control Laws for an Aerial Manipulator
(2019-05-10)
One platform commonly used in modern control systems research is the quadcopter unmanned aerial vehicle (UAV). This platform finds many uses in both civilian and military aviation, such as aerial surveillance and imaging, ...
Characterization of Hydrophobic Nanoporous Particle Liquids for Energy Absorption
(2016-12)
Recently, the development of hydrophobic nanoporous technologies has drawn increased attention, especially for the applications of energy absorption and impact protection. Although significant amount of research has been ...
Incorporation of Depth Feed for Prototype Rover Video and Other Usability Improvements
(2019-12-14)
NASA has been mandated by the US government to return to the moon within the next five years, meaning that functional technology for lunar exploration must be developed and tested in order to reach that goal. While most ...
Solution Space Exploration in Model-Based Realization of Engineered Systems
(2016-05-13)
With growing interest in the model-based realization of engineered systems there is a need for developing methods to explore the solution space that is defined by models that approximate reality and are typically incomplete, ...
