After scanning each paper, nine review articles and 14 new studies were selected …

Review Of Literature On Efficacy And Safety Of Birthing Positions With Emphasis On International Cultural Influences On Obstetric Care, Ava E. Retsch

Theses

• Background: When examining most non-Westernized societies, parturients hold all the power in the birthing space with traditional birth attendants and medical staff serving as guiding forces and protectors, not directors of the process. Social media in Western countries is filled with stories from birthing people who felt unsupported, ignored, or discriminated against by their healthcare providers; this is particularly prevalent in parturients who express a preference for non-supine birthing positions. Methods: This work is a review of the existing body of literature on quantitative and qualitative outcome measures of alternative birthing positions. In total, 44 articles were analyzed …

Integration Of Blockchain And Cryptographic Techniques For Location Based Services, Rashed Al Shamali

Theses

As digital systems continue to evolve in complexity, protecting user identities and ensuring the secure transmission of data has become paramount. Conventional techniques such as passwords and digital signatures are often insufficient to address modern security threats unless paired with more sophisticated technologies. This thesis proposes a framework that integrates Blockchain Technology with Elliptic Curve Cryptography (ECC) to fortify identity verification protocols and enhance location-obscuring methods. Blockchain’s inherent features of decentralization, immutability, and non-repudiation makes it an ideal platform for secure data exchange. When combined with ECC, which provides robust encryption with smaller key sizes, the system achieves a heightened …

The Uae’S Readiness For Technology Export: The Case Of Ai, Reem Tamer Aldandashi

Theses

Export diversification is one way for the UAE to sustain and flourish its economy. Although UAE is an oil-rich country, it needs to search for and incubate future exports besides the existing ones to keep the wheel of the economy moving, increase the employment rate, and strengthen the country from any future economic strokes. While looking at the technology spread and Artificial Intelligence (AI) focus and efforts in UAE, much research investigated the outcomes of digitization on the UAE economy and its technological strength and competitiveness. At the same time, no one has searched for the possibility of having one …

Ownership Topology Of Vertically-Scaled Agile, William Dabney

Theses

Much as Scrum, Kanban, and XP are used to structure team-level agility, those wishing to take agility beyond the team level often turn to proven solutions. The most popular, which aim to scale development by adding teams under a shared collective ownership rather than separating them into discrete units, are the Scaled Agile Framework (SAFe), Large Scale Scrum (LeSS), and Nexus. These frameworks advocate for aligning ownership subdivisions along features rather than code, which allows teams working on the same product to do so autonomously. While the benefits of this have been researched, the topology of ownership in these frameworks …

Gen-Acceleration: Pioneering Work For Hardware Accelerator Generation Using Large Language Models, Durga Lakshmi Venkata Deepak Vungarala

Theses

Optimizing computational power is critical in the age of data-intensive applications and Artificial Intelligence (AI)/Machine Learning (ML).

This study explores a state-of-the-art hardware accelerator; Gemmini is studied; we leveraged the open-sourced tool. Furthermore, we developed a Hardware Accelerator in the study we compared with the Non-Von-Neumann architecture. Gemmini is renowned for efficient matrix multiplication, but configuring it for specific tasks requires manual effort and expertise. We propose implementing …

Evaluation Of Electrical Grid Resilience Based On Φλεπ Metrics And Integration Of A Nuclear Power Plant, Abdulla Darwish Alblooshi

Theses

This study analyzes electrical grid resilience, the evaluation methods, and resilience metrics, as well as the impact of a nuclear power plant as a base-load supplier on the resilience of an electrical grid during extreme events such as high-speed winds or hurricanes. The case study was implemented on a 10-generator 39-bus system (New England) using PowerWorld, and the data extraction and plotting were performed using MATLAB. The wind speeds, fragility curves, and time-to-restore function were randomly created based on previous models, and their values were extracted from MATLAB calculation using randomly generated but uniformly distributed wind speeds. The resilience metrics …

Characterization Of 3d Printed Lattice Structures Used In The Design Of Modified Compression Release Stabilized Transhumeral Prosthetic Sockets, Jade Myers

Theses

Abstract A prosthetic socket is the critical interface between a person and their prosthetic device. Pressure, shear, and friction experienced by the residual limb from wearing a socket can damage soft tissue. While Compression Release Stabilized (CRS) style sockets are beneficial for enhancing prosthesis stability, range of motion, and control, the abrupt differences in compression throughout the socket present risks for tissue damage to the residual limb. A socket design that enables clinicians to control a progressive decrease in firmness in the transition areas between compression and release could mitigate such undesirable effects. Density-graded lattice structures designed and produced with …

Demonstration Of A Hybrid Electroabsorption Modulator/Photovoltaic Device For Space-Based Free Space Optical Communication And Power Generation, Emily Kessler-Lewis

Theses

The emergence of proliferated low-Earth orbit (pLEO) constellations using small satellites has resulted in significant interest in lowering the size, weight, and power (SWaP) of mission critical subsystems. III-V semiconductors are the class of materials typically used for photovoltaic (PV) arrays for satellites due to their exceptional efficiencies of upwards of 35 % and ability to be made thin, flexible, and lightweight. This is contrasted with the high SWaP communication system, which utilizes a radio frequency (RF) transceiver in order to communicate with a ground station. A lower SWaP alternative to the RF transceiver is to transmit data using free …

Understanding Drivers Of Local Opposition To Renewable Energy Projects To Improve Adoption Of Clean Energy, Bryson Russell

Theses

The world faces a crisis; climate change is beginning to show more damaging effects on our planet. Without human intervention to stop these effects from worsening, they are predicted to escalate, such as mass extinctions and more frequent natural disasters. In order to curb climate change, the world must begin a transition to renewable and green energy sources as soon as it is feasible. One of the potential forces slowing the transition to renewables is the public's perception and opposition. For example, a spot for a photovoltaic solar farm may be the most economically optimal, but if the community does …

A Prototype Of Simple Implantable Optofluidic Device Enabled By 3d Printing Technology, Yu Chang

Theses

Superhydrophobic surface-based optofluidics have been introduced to biosensors and unconventional optics recently with unique advantages such as dynamic adjustable optical properties, low light loss, and high versatility. Most of these platforms were manufactured by Microelectromechanical systems (MEMS) manufacturing technology and usually need to be further packaged or sealed. Although the MEMS-based technology is prone to make an integrated device containing sensing and electronic components, the technology may constrain the design of the morphology of the featured structures. For example, it was hard to manufacture a three-dimensional, fully enclosed round channel with complex structures along the inner surface. The limitations could …

One Man’S Trash, Jordan Tavan

Theses

This thesis explores perception through ambiguous mixed-media sculpture in order to create the potential for people to question their assumptions of what “is.” Judgments, categorization, and assumptions are big parts of the ways we make sense of our world. Often, we’re wrong about them. This artwork is created in response to the lifelong experience of existing outside the lines – the experience of breaking social rules and the desire for others to realize the potential for multiple truths.

Identifying The Drivers Of Pollen Limitation In Apples (Malus Domestica) Within The Urban Orchards Of St. Louis, Mo, Jordan Hathaway
