Raw Depth Image Enhancement Using A Neural Network, Xuan Xie

All Graduate Theses and Dissertations

The term image is often used to denote a data format that records information about a scene’s color. This dissertation object focuses on a similar format for recording distance information about a scene, “depth images”. Depth images have been used extensively in consumer-level applications, such as Apple’s Face ID, based on depth images for face recognition.

However, depth images suffer from low precision and high errors, and some post-processing techniques need to be utilized to improve their quality. Deep learning, or neural networks, are frameworks that use a series of hierarchically arranged nonlinear networks to process input data ...

Application Of Computational Fluid Dynamics To Determine Gas Expansion Factors Of Differential Pressure Flow Meters, Patrick L. Campana

All Graduate Theses and Dissertations

The purpose of this research was to investigate if computer simulations could be used to accurately predict gas expansion in differential pressure flow meters. Differential pressure flow meters are used to measure the flow rate of pressurized liquids and gases through pipes. Computer simulations of liquid and gas flows were conducted for three distinct differential pressure flow meter geometries: Classical Venturis, Stand Concentric orifice plates, and wedge meters.

Gas flows were modeled as dry air using the assumption of a perfect gas. Expansion effects were modeled using the ideal gas law. Computer simulations of Classical Venturi and Standard Concentric orifice ...

A Laboratory Study On The Geometric Effects Of Piano Key Weirs On Scour For Non-Cohesive Substrates And Simple Mitigation Techniques, Wyatt Lantz

All Graduate Theses and Dissertations

Sustainable flood control infrastructure is needed as climate change continues to produce more extreme precipitation events, as our water infrastructure continues to age, and as populations continue to grow and expand. Non-linear weirs, such as labyrinth and piano key weirs, are sustainable passive flood-control structures due to their improved hydraulic performance, and low maintenance and construction costs. However, like other structures, these weirs are susceptible to local scour, which is removal of soil and rock due to hydraulic forces. The scour phenomenon is a complicated process dependent upon multiple variables. There is limited information for non-linear weirs with little directed ...

Analysis Of Fluid Flow In Redox Flow Batteries, Erfan Asadipour

Engineering and Applied Science Theses & Dissertations

Redox flow batteries (RFB) hold great potential for large-scale stationary energy storage. However, their low energy density compared to other energy storage systems must improve for feasibility. Electrolyte flow distribution affects current density distribution and providing a uniform current density distribution is one way to improve RFB performance. Additionally, reducing the power consumption of the electrolytes’ pump as a source of energy loss in RFB systems increases their efficiency. Investigating both subjects requires analysis of the fluid dynamics in RFB cells.

In this thesis, a novel, computationally cost-effective hydraulic-electrical analogous model (HEAM) was developed to study fluid dynamics by implementing ...

Immunomodulatory Biomaterials For Cancer Immunotherapy, Larry Donnell Stokes Jr

Honors Theses

Cancer immunotherapy has become an effective treatment in the toolbox of oncologists. Immunotherapy offers a less toxic alternative to standard cancer treatments such as chemotherapy and can have prolonged curative effects to decrease cancer recurrence. Today, many drugs and biological agents have been developed that target the immune system and elicit an antitumor/cancer response. These agents are known collectively as cancer immunotherapies. While immunotherapies have radically improved treatment outcomes for many cancer patients, there are drawbacks to using these treatments. Immunotherapy treatments have poor clinical responses in patients with tumors that lack immunogenicity. Some of the treatments also pose ...

Design Of An Undergraduate Laboratory Experiment Utilizing A Stirred-Tank, Jacketed Bioreactor, Brennen Middleton

Honors Theses

Bioreactors are utilized in many industries, such as the food, alternative fuel, and pharmaceutical industries, to design and manufacture products. Unlike the similar chemical batch reactors utilized in many chemical processing facilities, bioreactor utilization requires engineers to consider a wider range of operating conditions and parameters. This results in a more complex reaction system and controls network. Due to this, it is imperative for chemical and biomedical engineering students to not only understand the theory surrounding these reactor systems, but also understand how to properly design and perform operating procedures with these systems. Thus, it was determined to create an ...

Design And Analysis Of A Process To Convert Methanol Into Dimethyl Ether, Elisa M. White

Honors Theses

A recent economic downturn led to the loss of a contract for a company that sells methanol. The company has two options to recover some of the profit lost from the contract termination.

Three-Phase Unfolding Based Soft Dc-Link Converter Topologies For Ac To Dc Applications, Dorai Babu Yelaverthi

All Graduate Theses and Dissertations

Battery electric vehicles (BEVs) and plugin hybrid electric vehicles (PHEVs) are more efficient than internal combustion-based vehicles. Adaption of EVs will help reduce the carbon emissions produced by the transportation sector. The charging infrastructure has to grow at a rapid pace to encourage EV adaption. Installing higher capacity fast chargers will help alleviate the range anxiety of battery electric vehicle customers. More public charging stations are required for the full adaption of EVs. Utility power is distributed as ‘alternating current.’ A battery requires ‘direct current’ (DC) source to charge it. Hence a power converter that converts AC source to DC ...
