Examining The Impact Of Student Motivation On Performance In Mechanical Engineering Design Courses, Elisabeth Kames
Examining The Impact Of Student Motivation On Performance In Mechanical Engineering Design Courses, Elisabeth Kames
Theses and Dissertations
Design courses are an integral component of undergraduate engineering education. Design is recognized as one of the primary responsibilities of an engineer in industry. New designs are responsible for stimulating sales and company growth.1 This dissertation outlines a study seeking to explore the impact of student motivation factors on course performance of mechanical engineering students in design courses. The first design course, cornerstone design, takes place during the first semester of freshman year. The second course, capstone design, takes place during the student’s final year of undergraduate study. An adapted version of the Motivated Strategies for Learning Questionnaire (MSLQ) is …
Design, Analysis, And Demonstration Of A Multipurpose Fluid Tank Dynamics Characterization Platform, Cameron Ian Hume
Design, Analysis, And Demonstration Of A Multipurpose Fluid Tank Dynamics Characterization Platform, Cameron Ian Hume
Theses and Dissertations
The development of a highly versatile multiphase fluid tank characterization platform is essential to the analysis and improvement of propellant storage tanks. The performance of these tanks is highly critical to the safety and performance of their carriers, especially in the space industry where the propellant makes up the overwhelming majority of the mass of the vehicle. This thesis outlines the design and development of a linear stage used to test and validate the characteristic of multiphase fluids inside moving specific tanks. This document will walk through the steps taken to bring a new linear stage to life, from the …
Nonlinear Attitude Control For A 6u Cubesat With A Flexible, Deployable Boom, Jared Walker
Nonlinear Attitude Control For A 6u Cubesat With A Flexible, Deployable Boom, Jared Walker
Theses and Dissertations
A satellite attitude control system was developed in MathWork’s Simulink for a 6U CubeSat with a flexible appendage payload. The flexible appendage is a boom that is able to store into a compact size and deploy out to 1 meter. The boom deploys a sensor attached to the end of the boom. The boom/sensor payload was modeled as a spring-mass-damper system. The equivalent spring constant of the payload was determined by the the natural frequency of the system. A modal analysis in ANSYS Mechanical was used to determine the natural frequencies and mode shapes of the payload. The attitude control …
Living Docks: Structural Implications And Determination Of Force Coefficients Of Oyster Mats On Dock Pilings In The Indian River Lagoon, Ryan Christiansen
Living Docks: Structural Implications And Determination Of Force Coefficients Of Oyster Mats On Dock Pilings In The Indian River Lagoon, Ryan Christiansen
Theses and Dissertations
Brevard County, Florida, is facing rapid population growth and increased pollution entering the Indian River Lagoon (IRL), impairing water quality and damaging the ecosystem. This is problematic not only for public health and environmental stability, but also for the economy. The Living Docks initiative was created to combat environmental degrade in the lagoon and restore natural functions back to the ecosystem. With increased urbanization along coastal systems, there is opportunity for new forms of ecological engineering such as Living Docks, which attaches oyster mats to dock pilings as a means to promote the growth of filter feeding organisms. It is …
Model Optimization For Edge Devices, Adolf Anthony D’Costa
Model Optimization For Edge Devices, Adolf Anthony D’Costa
Theses and Dissertations
Edge devices are undergoing groundbreaking computing transformation, which lets us tap into artificial intelligence, quantum computing, 5th generation network capability, fog networking, and computing complex algorithms. Edge systems have substantial advantages over the conventional system in terms of scalability, optimized resources, reliability, and security. The proliferation of such resource-constrained devices in recent years has resulted in the generation of a large quantity of data; these data-producing devices are attractive targets for applications of machine learning. Machine learning models, especially deep learning neural networks, produced models that have high accuracy and prediction capability, but it comes at the cost of computation …
General Aviation Airport Runway Incursions: A Qualitative Approach To Examining Reasons For, Barriers To Addressing, And Lessons Learned From Airport Managers' First-Hand Experiences, Indira Maharaj
Theses and Dissertations
The purpose of the study was manifold: (a) to understand the reasons for runway incursions (RIs) at general aviation (GA) airports, (b) to describe the barriers to addressing runway incursions at GA airports, and (c) to describe the lessons learned from addressing runway incursions at GA airports. This study was based primarily on a phenomenological research design, which led to a set of inductively derived conjectures. The study’s sample consisted of 10 GA airports that had at least 10 times the number of GA operations than the number of air carrier (commercial) operations as reported in the Air Traffic Activity …
A Study On Reaction Rate Factors Of A Single-Step Combustion Mechanism For Gasoline Hcci Combustion, Pakawat Panuwatsuk
A Study On Reaction Rate Factors Of A Single-Step Combustion Mechanism For Gasoline Hcci Combustion, Pakawat Panuwatsuk
Theses and Dissertations
Homogeneous Charge Compression Ignition (HCCI) engine has been invented to achieve the advantages of both diesel and gasoline engines. HCCI engine can run with a higher compression ratio like diesel engine in order to achieve high thermal efficiency. Meanwhile, like gasoline engine, the engine produces less NOx gas and particulate matters than diesel engine. However, there are several difficulties associated with HCCI combustion, which still require further development to the engine. The most important issues are autoignition timing and narrow operational range. In order to develop an HCCI engine, a numerical simulation can significantly save cost, time and resources over …

Improving Wake-Up-Word And General Speech Recognition Systems, Gamal Mohamed Bohouta
Theses and Dissertations
Automatic Speech Recognition (ASR), a technology that allows a machine to recognize the utterances spoken into a microphone by a person and then converts it to text, is commonly used for different types of applications, such as command and control systems, personal assistant systems, medical systems, disabilities systems, dictation systems, telephony systems, and embedded applications. Due to its extensive use, interest in ASR technology has surged among inventors and researchers alike. They have worked diligently to improve the performance of the ASR systems by developing several techniques or approaches in different aspects,such as enhancing features, training an acoustic model, enhancing …
