Design And Fabrication Of Transparent Ultrasonic Transducers For Optoelectronic Applications, Stephen Colby Warren Dec 2023

Design And Fabrication Of Transparent Ultrasonic Transducers For Optoelectronic Applications, Stephen Colby Warren

Theses and Dissertations

Acoustic levitation utilizes general principles of ultrasonics to trap particles in midair without external support. This is done by creating an array of ultrasonic transducers to propagate sound waves to a focused point in space. In order to optimize the particle trap it is necessary to design transducers that can produce enough sound to create pressure pockets. In this work I examine the fundamental principles of acoustics by testing the sound pressure levels (SPL) of a known transducer in both air and water mediums. A comparison between domed and bimorphed transducers are also examined. Experimentation was performed on the feasibility …

Lcc Mse Walls, Joel Smith Dec 2023

Lcc Mse Walls, Joel Smith

Theses and Dissertations

Lightweight cellular concrete (LCC) is mainly a mixture of water, cement, and foam bubbles. LCC generally has a cast density between 20-60 pcf and an air content between 49-84%. LCC is often used as a fill material because it has a low unit weight which reduces settlement. LCC is increasingly being considered as a backfill behind Mechanically Stabilized Earth (MSE) walls and embankments. Although engineers are using LCC in MSE walls or free face walls (MSE wall without the concrete panels or reinforcements), there is presently a lack of information regarding the performance and behavior of LCC to guide them. …

Once Upon A Time, Again: Exploring The Function Of Fairy Tale Retellings, Mackenzie A. Parsons Dec 2023

Once Upon A Time, Again: Exploring The Function Of Fairy Tale Retellings, Mackenzie A. Parsons

Theses and Dissertations

With the invention of the printing press, fairy tales became limited by the idea of an "original" (Pettitt, 2009; Blamires, 2003). However, in the past century, the retelling and changing of fairy tales has become incredibly popular in all forms of media, such as print, film, ballet, musicals, etc. Despite Western populations' familiarity with these tales, the demand for such retellings continues to rise, with the storytellers finding great financial success with each "new" version they provide. Researchers have many varying opinions on the reasons for such intense responses to retold fairy tales, but there is a gap of research …

Evaluation Of Unmanned Aerial Vehicle Flight Parameters That Impact Stockpile Volume Computations, Nicole Marie Hastings Dec 2023

Evaluation Of Unmanned Aerial Vehicle Flight Parameters That Impact Stockpile Volume Computations, Nicole Marie Hastings

Theses and Dissertations

Stockpile volumes are monitored by their companies as the product (i.e., aggregate, soil) is moved in and out of the facilities to ensure minimal product loss. Companies are mandated to report product movement to the government to ensure that the aggregate and soil is going where it is supposed to go. Many tools are used to monitor stockpile volumes including truck scales (to weigh incoming and outgoing trucks), light detection and ranging (LiDAR), Global Navigation Satellite System (GNSS) equipment, and unmanned aerial vehicle (UAV) photogrammetry. These processes give a good estimate of stockpile volumes. Errors in these estimates typically come …

A Tunable System For High Frequency Bioimpedance Plethysmography, Daniel H. Tebbs Dec 2023

A Tunable System For High Frequency Bioimpedance Plethysmography, Daniel H. Tebbs

Theses and Dissertations

Bioimpedance measurements are useful for determining a variety of biological conditions. By accounting for small impedance variations due to the arterial pulse, the effect of the blood can be studied more closely. The quasi-circulator system presented enables monitoring of pulsatile impedance changes with input frequencies above 1 MHz. The adjustable Rmatch allows for dynamic tuning of the system to increase sensitivity. By tuning Rmatch to be near the match point, the pulsatile signal in the output magnitude can be amplified, and tuning Rmatch to be at the match point causes the pulsatile signal in the output phase to be amplified. …

Dynamic Segmental Kinematics Of The Lumbar Spine During Diagnostic Movements, Paul Mcmullin Dec 2023

Dynamic Segmental Kinematics Of The Lumbar Spine During Diagnostic Movements, Paul Mcmullin

Theses and Dissertations

While lumbar kinematics can be measured in vivo, most measurements are invasive (such as percutaneous bone pins), provide high doses of radiation (such as biplane fluoroscopy), or are taken with the patient in a static position (such as MRIs). Recent work suggests that lumbar kinematics can be determined by dynamic measurements of epidermal strain in the lower back. This work aims to develop and examine a method of examining lumbar kinematics via optoelectronic motion capture utilizing skin-mounted markers in the lumbar region. Two studies were performed. One study examined lumbar epidermal strain in 28 asymptomatic subjects during diagnostic movements, while …

Soft Robot Trajectory Generation: Enabling Soft Robot Arms To Reliably And Effectively Perform Real World Tasks Through Optimization, Haley P. Sanders Dec 2023

Soft Robot Trajectory Generation: Enabling Soft Robot Arms To Reliably And Effectively Perform Real World Tasks Through Optimization, Haley P. Sanders

Theses and Dissertations

The robotic platform presented in this thesis is underdamped with high inertia and can store potential energy in its compliant joints, making it ideal for many different types of real-world tasks for which traditional rigid-robots are ill-suited. Some real-world tasks suited to soft robots include high impact tasks like hammering a nail into a wall or moving heavy objects with other robot or human teammates while using relatively little power. Some of the same characteristics which make soft robots useful, such as their underdamped, highly compliant joints, also make motion planning and control for soft robots difficult. In this thesis, …

More About Mulek Dec 2023

More About Mulek

Insights: The Newsletter of the Neal A. Maxwell Institute for Religious Scholarship

Another possible clue of the existence and escape of Mulek (see Insights, March 1984, and Update, February 1984), son of Zedekiah, has been noticed by Benjamin Urrutia. 2 Kings 25:1-10 reports that Nebuchadnezzar and "all his host" scattered "all the men" and "all [the king's] army" and burnt "all the houses of Jerusalem" and with "all the army" destroyed the walls. Ben points out that in the midst of all this, 25:7 omits the word "all" when it reports that "sons" of Zedekiah were killed, refuting, perhaps, the idea that all …

New Compilation Of Gnostic Scriptures Is Now Available Dec 2023

New Compilation Of Gnostic Scriptures Is Now Available

Insights: The Newsletter of the Neal A. Maxwell Institute for Religious Scholarship

Many early Christians sought gnosis (knowledge) by revelation, inspiration and testimony; hence, they were known as Gnostics. But eventually they were branded as heretics and their writings were suppressed. Although many gnostic views were eccentric, their emphasis on revelation and ritual reflected important aspects of early Christianity that soon were lost. Now many of their writings are conveniently available in a new English translation.

Drop Retention And Departure In Shear Flow On Structured Superhydrophobic Surfaces, Blake Morgan Lyons Dec 2023

Drop Retention And Departure In Shear Flow On Structured Superhydrophobic Surfaces, Blake Morgan Lyons

Theses and Dissertations

Water is often found adhering to surfaces in droplet form. Droplets can develop as a result of precipitation, condensation, or chemical reactions. Drops are retained or held on a surface due to a retention force exerted on the drop by the surface. This retention force is a function of the surface tension of the liquid, drop geometry, and the contact angle between the drop and the surface. When external or body forces exceed this retention force the drop begins to move. This thesis seeks to understand and quantify the forces present at the point of droplet departure once it begins …

The Role Of Myocyte Enhancer Factor 2d In Beta-Cells: Implications For Glucose Homeostasis And Cell Survival, Jacqueline Elise Crabtree Dec 2023

The Role Of Myocyte Enhancer Factor 2d In Beta-Cells: Implications For Glucose Homeostasis And Cell Survival, Jacqueline Elise Crabtree

Theses and Dissertations

Myocyte Enhancer Factor 2D (Mef2D) is a member of the Mef2 family. As a transcription factor, Mef2D regulates the expression of genes that impinge on cellular viability, tissue development, and fuel metabolism. Interestingly, Mef2D function appears to be tissue dependent. The function of Mef2D appears to be tissue-specific, with differences in activity in the immune system, neuronal tissue, and muscle. Here, we review the published literature describing the role of Mef2D across tissues. Little is known about the role of Mef2D in the beta-cell. To determine the function of Mef2D in the beta-cell, we built overexpression and knockdown cell lines. …

Development Of A Submerged Hydraulic Jump Prediction Method Using Documented Fatal Incidents At Low-Head Dams, Caleb Mccurry Dec 2023

Development Of A Submerged Hydraulic Jump Prediction Method Using Documented Fatal Incidents At Low-Head Dams, Caleb Mccurry

Theses and Dissertations

Low-head dams are known to be dangerous due to a recirculating current that, when formed, drowns recreationalists who become trapped in the current. Efforts to mitigate the hazard of low-head dams have led to the compilation of a database of low-head dams with proven fatalities. Additionally, flume-based experiments along with well-known hydraulic equations have been used to create a spreadsheet-based system for predicting the occurrence of the dangerous recirculating current, otherwise known as a submerged hydraulic jump. The premise of the spreadsheet is that if the normal depth calculated with the Mannings Equation for the downstream reach is between the …

The Effect Of Percussive Massage On The Maintenance Of Skeletal Muscle Health During Limb Unloading, Mohadeseh Ahmadi Dec 2023

The Effect Of Percussive Massage On The Maintenance Of Skeletal Muscle Health During Limb Unloading, Mohadeseh Ahmadi

Theses and Dissertations

A period of skeletal muscle disuse leads to muscle mass and strength loss and compromised metabolic health. Several studies suggest that passive mechanical stimulation may protect against the detrimental effects of disuse in skeletal muscle. This study assessed the effect of the twice-daily application of percussive massage in mitigating the adverse effects of muscle disuse during ten days of leg unloading. Seventeen participants (7 women and 10 men; 18-35 yrs.) were randomly assigned to either control or massage groups, both undergoing leg unloading. The data revealed that both groups similarly experienced significant reductions in muscle strength (-14%±5.9; p<.0001), quadriceps volume (-4.2%±2.8; p<.0001), myofiber cross-sectional area (-8.2%±1.8; p<.0001), and maximal mitochondrial respiration (-20%±9.1; p<.0001). Fatty acid-supported respiration decreased in the control group (-30.4±18.5%; p= 0.0008) and remained unchanged in the massage group. Hydrogen peroxide (H2O2) flux normalized to oxygen consumption exhibited a significant interaction between group and time, particularly in the absence of ADP, where H2O2 flux increased only in the control group (control: 29.9±26.5%, massage: -13±22.6%; p=0.01). There was no change in the H2O2 flux after the addition of ADP. In conclusion, ten days of limb unloading resulted in diminished muscle size, strength, and mitochondrial respiration. Percussive massage was insufficient to prevent the loss of muscle mass, force production, or carbohydrate-supported respiration. However, it exhibited potential protective effects against the decline in mitochondrial fatty acid-supported respiration.

View Dependent Simplification And Tessellation For Real-Time High Quality Rendering Of 3d Meshes, Dallin M. Hagman Dec 2023

View Dependent Simplification And Tessellation For Real-Time High Quality Rendering Of 3d Meshes, Dallin M. Hagman

Theses and Dissertations

The increasing complexity of 3D meshes and growing disparity in performance between high and low-end hardware necessitates more efficient rendering techniques that do not sacrifice visual quality. To support as many hardware configurations as possible, producers of 3D content provide several resolutions of each mesh. Low-end hardware is typically restricted to low-resolution meshes to maintain performance similar to their high-end counterparts, sacrificing visual appeal. However, the presence of hardware tessellation in nearly all modern GPUs presents the opportunity to render high-resolution versions of simplified meshes on low-end hardware with little computational cost. Some research has been conducted into this opportunity, …
