Performance Prediction For Hub-Based Swarms, Puneet Jain

Theses and Dissertations

Optimization problems lie at the core of improving performance in various tasks, ranging from day-to-day work scheduling to coordinating robots in a warehouse fulfillment center. Distributed swarm systems provide a robust and adaptive solution approach to many optimization problems. Instead of using one really sophisticated agent, multiple smaller less sophisticated agents can provide the flexibility to evaluate more options and still provide a "good" answer. This dissertation uses graphs to model, analyze, and simulate swarm behavior, primarily to predict the time-to-converge (TTC) and success probability. First, we use a bipartite model for the distributed best-of-N problem, and show how the …

Faculty Publications

Researchers have examined the influence of the factors on reducing return rates in retailing over the years. However, the returns experience is often an overlooked way to drive customer engagement and repeat sales in the now ubiquitous omnichannel setting. The focus on returns prevention in existing research overshadows management’s need to understand better the comprehensive mechanics linking the customer in-store return experience with their repurchase actions. Recognizing the need to bridge different stages of the returns management process, this research aims to explore the facilitators and barriers of in-store return activities.

A Comparison Of Rfssw And Rsw For Automotive Manufacturing, Damon Michael Gale

Theses and Dissertations

Historically, automotive body panels have been made of steel and joined by a process called resistance spot welding (RSW). However, in efforts to reduce vehicle weight to improve the energy efficiency of the vehicle, automotive manufactures have begun substituting aluminum in place of steel. While aluminum can be joined with RSW, a myriad of challenges arise from doing so. These challenges result in less consistent weld quality and accelerated electrode wear. Refill friction stir spot welding (RFSSW) is an emerging joining technology that could replace RSW as it is believed to be capable of creating superior joints in thin sheet …

Non-Compete Clauses Mysteriously Appearing Out Of Thin Air: The Catastrophic Flaws Of Inevitable Disclosure Doctrine In The New Ftc Non-Compete Rule And Beyond, Bradford P. Anderson

Southern Illinois University Law Journal

The Federal Trade Commission (FTC) recently adopted a new regulation that prohibits non-compete clauses for employees (Non-Compete Rule). Simultaneously, the FTC allowed the inevitable disclosure doctrine to continue in existence, even though such doctrine is tantamount to a non-compete clause. Under the inevitable disclosure doctrine, an employer posits that an employee will be unable to abide by her/his confidentiality obligations, and therefore unable to resist use and disclosure of proprietary information at an alternative employer. As a result, prescient, mind-reading judges portend future conduct under the inevitable disclosure doctrine and can issue an order banning or restricting future employment, thereby …

Theses and Dissertations

Flood early warning systems are crucial for disaster risk reduction strategies, enabling communities to take timely action against threats. However, the effectiveness of these systems depends on accurate and timely hydrological data, particularly river discharge and water level measurements. Unfortunately, many regions, face significant challenges in obtaining hydrological data, especially discharge data due to outdated rating curves, high equipment costs, and logistical constraints. Water level measurements, by contrast, offer reduced uncertainty and are often more accessible, providing an alternative for hydrological modeling in data-scarce regions. To address these limitations, we developed and validated the Discharge-to-Water Level Conversion Using Monthly Duration …

Application Of Systems Engineering Principles In A Reliability Assessment Of Air- Cooled Heat Exchangers, Dheerajkumar R Narang

Harrisburg University Experiential Learning Projects

A significant systems engineering challenge exists due to the lack of a comprehensive methodology that holistically addresses both the static and dynamic components of air-cooled heat exchangers. Traditional methodologies often overlook the dynamic components—such as fin blades, electrical motors, gearboxes and propellers (fans)—that are integral to the overall performance and reliability of the air-cooled heat exchangers. The absence of an integrated framework that considers the interdependencies and interactions between mechanical and dynamic components complicates the task of accurately assessing the remaining life and ensuring the reliability of the entire system.

This article proposes a holistic RLA and reliability engineering framework …

Utility Of Immobilized Metal Salens As Electrocatalysts: Fuel Cells And Organic Electrosynthesis, Zachary A. Nguyen, Shelley D. Minteer

Chemistry Faculty Research & Creative Works

There have been significant advancements in the electrosynthesis of fuels and organic molecules, making it an increasingly sustainable and cost-effective alternative to traditional chemical redox reagents. Early versions of these systems faced challenges in chemo selectivity due to high applied overpotentials, which have been mitigated with the introduction of molecular electrocatalysts, like metal salens (MSalens). These MSalens reduce the required overpotentials, increase turnover numbers (TON), and have simple modularity within their ligand structure allowing for tunable selectivity. While these MSalen electrocatalysts are typically used homogeneously for engineering simplicity, downstream separations are often costly and time-consuming. Immobilization of MSalens addresses these …

Microstructure Analysis Of Different Naoh Molarity Towards Fly Ash Geopolymer For Underwater Concreting Material, F. H.A. Zaidi, A. Romisuhani, M. M.A.B. Abdullah, W. M.W. Ibrahim, M. I.A. Bistamam, A. S. Sauffi, L. Y. Li

School of Engineering, Computing and Mathematics

Geopolymer concrete is a new sustainable and environmentally friendly composite with great potential to replace conventional concrete that is mostly produced by ordinary Portland cement (OPC). Binders used for geopolymer concrete such as fly ash and blast furnaces are mostly industrial wastes or by -products containing high silica and aluminium content that act as stimulants for geopolymerization. Furthermore, geopolymers also exhibit better durability and corrosion resistance than OPCs. However, material subjected to underwater placement method typically exhibit a decrease in properties. While geopolymer has not been widely used as underwater concreting material, this research is purposed to identify the effect …

A Mechanistic Study Of Silicon Nanocrystal Formation Via Solid State Synthesis, Katherine Mccarthy Weinfurter

Dissertations and Theses

Silicon nanocrystals (SiNCs) show promising physiochemical properties that could be used in industrial applications. The production of SiNCs through solid-state synthesis is ideal due to relatively low cost of equipment and chemical reagents, as well as the ability to scale-up production. A widely known and commonly used precursor previously used in solid-state synthesis for SiNCs, hydrogen silsesquioxane (HSiO_1.5), was discontinued in chemical manufacturing, which has led to researching alternative precursors (or starting materials). We have identified that there is a gap of knowledge related to producing these precursors, as well as the mechanistic understanding of the chemical reactions …

Nicholas, M. Kiernan, R. A. Burton, L. Belfield, G. Montagut, A. Benavente, W. Vevers, T. Gabaldón, Z. Brookes, P. Casas-Agustench

School of Health Professions

BACKGROUND: Propolis mouthwash (PROP-M) has demonstrated antibacterial properties like those of chlorhexidine mouthwash (CHX-M). However, its impact on the abundance of oral nitrite-producing species (NPS) and nitrite-producing activity (NPA) remains unexplored.

METHODS: Forty-five healthy individuals were randomised into 2 groups to rinse their mouth twice a day for seven days with either CHX-M ( n  = 21) or PROP-M ( n  = 24). Metagenomic sequencing (16S rRNA) was performed on saliva samples collected before and after each treatment. Additionally, salivary biomarkers and blood pressure were measured.

RESULTS: CHX-M increased the relative abundance of NPS ( p  < 0.001) but significantly impaired the NPA ( p  < 0.001) compared to baseline and PROP-M. No significant differences in the relative abundance of NPS and NPA were observed in the PROP-M group. However, a significant increase of plasma nitrate (+7 µmol/L, p  = 0.047) and a decrease in systolic BP (-2 mmHg, p  = 0.022) was observed in this group compared to the baseline.

CONCLUSION: The results indicate …

Orosipon Kan Bikolnon: Interrupting The Nation, Raniela Barbaza

Kritika Kultura

If narration points to notions of fixity in terms of the position of the narrator and the subsequent structuring of events, orosipon, a Bikolnon word for “story,” suggests a refusal to fixity both in terms of the location of the narrator and the structure itself of the story: the story never stops being formed as it passes through multiple speakers. Orosipon, coming from the root word osip which approximates the verb “tell,” points to more than one person involved in an act of telling, which makes the act of telling proper to no one in particular: indeed, it is improper …
