Flight Characterization of Small Scale UAV

Creator:: Scheer, Jacob
Abstract:: The purpose of this thesis was to understand the relation between the actual performance and the design performance of the manufacturing plane which was designed for the 2016 Design/Build/Fly competition. The actual performance was determined using an Arduino Uno based system with data from an accelerometer, gyroscope and pitot tube....

Female Mold Fabrication Process Development with Pre-Impregnated Composite Materials for Application to Sub-Orbital Rockets

Creator:: Hayden, Muriel A.
Abstract:: The leading edge of a sub-orbital, sounding rocket dictates an aerodynamically optimal profile which is difficult to manufacture. The university level offers no current standard to produce rocket nose cones made with pre-impregnated composites. Of particular interest is the molding technique used to fabricate a nose cone. The focus of...

Phytoplankton of an ice-edge bloom in the Ross Sea, with special reference to the elemental composition of Antarctic diatoms

Creator:: Carbonell, Maria Consuelo
Abstract:: A phytoplankton bloom dominated by the pennate diatom Nitzschia curta (Van Heurck) Hasle was observed during January-February 1983 at a receding ice-edge in the Western Ross Sea, Antarctica. The core of the bloom was found between 100-150 Km from the ice-edge. Nitzschia curta cell densities up to 22 x 10⁶...

Geometric Chatter Stability Index for Milling and Modeling of Chip Pulling Effect

Creator:: Maulimov, Mukhtar
Abstract:: Prediction and mitigation of chatter vibrations in machining operations and optimizing overall machining mechanics are crucial for achieving greater productivity and manufacturing efficiency. This thesis first explores effect of directional relationships on chatter stability in milling process. Based on the directional relationships, a geometry-based chatter stability index (CSI) is proposed...

An approach to reduced-order modeling and feedback control for wave energy converters

Creator:: Shoori J., Hesam E.
Abstract:: Wave energy holds great promise to be part of the alternative energy portfolio that will provide independence from fossil fuels. As wave energy converter (WEC) technologies mature, designing effective control strategies to extract maximum energy, extend device life, coordinate WEC operation within an array, or mitigate negative impacts of a...

Cooling System Analysis of the Thrust Chamber

Creator:: Sazonov, Gleb
Abstract:: The purpose of the study was to analyze the possible combination of cooling systems, which are film cooling and regenerative cooling, and obtain the initial estimates of possible temperature reduction. The analysis was conducted in Ansys Fluent. The methodology includes four main steps that are the following: flow simulation, combustion...

Surface sediments of the Panama Basin : coarse components

Creator:: Kowsmann, Renato O.
Abstract:: The abundance and distribution of biogenic, terrigenous and volcanic particles in the Panama Basin are markedly dependent on bottom topography and dissolution of calcite in the deeper parts of the basin. Of the coarse fraction (>62μ), foraminiferal tests and acidic volcanic glass shards are concentrated on the Cocos and Carnegie...

A Ross-Macdonald Model with Vector Demography

Creator:: Reyes Grimaldo, Ricardo Noe Gerardo
Abstract:: Malaria is a vector-borne disease that has affected humans and other animals for a long time and which has shown high prevalence among different populations. During the beginning of the 20th century, Sir Ronald Ross and George Macdonald developed a model that represents the spread of malaria through the interaction...
