Design And Analysis Of Self-Tanked Stepwise Charging Circuit For Four-Phase Adiabatic Logic, William Morell, Jin Woo Choi

Michigan Tech Publications

Adiabatic logic has been proposed as a method for drastically reducing power consumption in specialized low-power circuits. They often require specialized clock drivers that also function as the main power supply, in contrast to standard CMOS logic, and these power clocks are often a point of difficulty in the design process. A novel, stepwise charging driver circuit for four-phase adiabatic logic is proposed and validated through a simulation study. The proposed circuit consists of two identical driver circuits each driving two opposite adiabatic logic phases. Its performance relative to ideal step-charging and a standard CMOS across mismatched phase loads is …

Election Reform And Campaign Finance: Did Alaska's Top 4 Nonpartisan Primaries And Ranked-Choice General Elections Affect Political Spending?, Zachary Albert, Robert G. Boatright, Lane Cuthbert, Adam Eichen, Wouter Van Erve, Raymond J. La Raja, Meredith Rolfe

Political Science

Objective: Ranked-choice voting (RCV) is increasingly seen as a way to reduce political polarization and increase voter choice in elections, but little is known about its effect on candidate fundraising. In 2022, Alaska held its first election using a nonpartisan Top 4 primary followed by a ranked-choice general election. We analyze the effect of this new system on campaign financing practices in state legislative elections. There are many reasons to expect RCV to increase campaign spending, broaden the donor pool, and prompt donors to support candidates to whom they would not otherwise contribute. Method: We measure changes in fundraising over …

Evidence-Based Approach For Prevention Of Surgical Site Infection, Mehmet Kursat Yilmaz, Nursanem Celik, Saad Tarabichi, Ahmad Abbaszadeh, Javad Parvizi

Rothman Institute Papers

Periprosthetic joint infection (PJI) is regarded as a critical factor contributing to the failure of primary and revision total joint arthroplasty (TJA). With the increasing prevalence of TJA, a significant increase in the incidence of PJI is expected. The escalating number of cases, along with the significant economic strain imposed on healthcare systems, place emphasis on the pressing need for development of effective strategies for prevention. PJI not only affects patient outcomes but also increases mortality rates, thus its prevention is a matter of vital importance. The longer-term survival rates for PJI after total hip and knee arthroplasty correspond with …

McKelvey School of Engineering Graduate Student Theses & Dissertations

This study explores the enhancement of ammonium and bicarbonate tolerance in Chlorella sorokiniana via EMS-induced mutagenesis, aimed at improving the microalgae's resilience and growth under high-stress conditions of elevated NH4+ and HCO3 concentrations. By mutating C. sorokiniana using EMS, we developed mutant strains capable of thriving in conditions that are inhibitory to the wild type strain. The successful adaptation of these strains demonstrates a significant increase in biomass production and tolerance to environmental stressors, highlighting the potential of EMS mutagenesis in industrial algal applications for sustainable biofuel production and environmental remediation.

Detecting Anomalies In Blockchain Transactions Using Machine Learning Classifiers And Explainability Analysis, Mohammad Hasan, Mohammad Shahriar Rahman, Helge Janicke, Iqbal H. Sarker

Research outputs 2022 to 2026

As the use of blockchain for digital payments continues to rise, it becomes susceptible to various malicious attacks. Successfully detecting anomalies within blockchain transactions is essential for bolstering trust in digital payments. However, the task of anomaly detection in blockchain transaction data is challenging due to the infrequent occurrence of illicit transactions. Although several studies have been conducted in the field, a limitation persists: the lack of explanations for the model's predictions. This study seeks to overcome this limitation by integrating explainable artificial intelligence (XAI) techniques and anomaly rules into tree-based ensemble classifiers for detecting anomalous Bitcoin transactions. The shapley …

Peat Fires And Legacy Toxic Metal Release: An Integrative Biogeochemical And Ecohydrological Conceptual Framework, Colin P.R. Mccarter, Gareth D. Clay, Sophie L. Wilkinson, Gabriel Sigmund, Scott J. Davidson, Muh Taufik, Susan Page, Emma L. Shuttleworth, David Mclagan, Grant Chenier, Alexandra Clark, James M. Waddington

School of Geography, Earth and Environmental Sciences

Peatlands are potent landscape sinks of natural and industrial toxic metals and metalloids (TMMs) but the long-term sequestration of TMMs in peatlands is at increasing risk due to climate change enhanced peatland fires. The ability of peatlands to retain TMMs results from a host of interacting hydrological, biological, geomorphological, and chemical feedbacks, which underpin peatland functionality in general. Fire is a transformative force that often disrupts these interactions and feedbacks, leading to the potential release of TMMs to our air, land, and water. Given that wildfire burned area and severity are increasing there is a need for a conceptual understanding …

Liquefaction Mitigation Of Sands With Plastic Fines Via Microbial Induced Partial Saturation, Maya Norris

Master's Theses and Capstones

Microbial Induced Partial Saturation (MIPS) is a sustainable and cost-effective approach to mitigate liquefaction; however, more research needs to be done to apply MIPS to a variety of different soil types and conditions. The investigation consisted of running a series of undrained strain-controlled cyclic Direct Simple Shear (DSS) tests on fully saturated samples with varying non-plastic fine and plastic fine content. Some tests have been conducted on MIPS-treated samples; however, more tests are needed to verify the results. Previous investigations have been conducted to evaluate the pore water pressure response of sands with added non-plastic fines with and without MIPS …

Predicting The Association Of Metabolites With Both Pathway Categories And Individual Pathways, Erik D. Huckvale, Hunter Moseley

Markey Cancer Center Faculty Publications

Metabolism is a network of chemical reactions that sustain cellular life. Parts of this metabolic network are defined as metabolic pathways containing specific biochemical reactions. Products and reactants of these reactions are called metabolites, which are associated with certain human-defined metabolic pathways. Metabolic knowledgebases, such as the Kyoto Encyclopedia of Gene and Genomes (KEGG) contain metabolites, reactions, and pathway annotations; however, such resources are incomplete due to current limits of metabolic knowledge. To fill in missing metabolite pathway annotations, past machine learning models showed some success at predicting the KEGG Level 2 pathway category involvement of metabolites based on their …

Surrogate-Based Multidisciplinary Optimization For The Takeoff Trajectory Design Of Electric Drones, Samuel Sisk, Xiaosong Du

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Electric vertical takeoff and landing (eVTOL) aircraft attract attention due to their unique characteristics of reduced noise, moderate pollutant emission, and lowered operating cost. However, the benefits of electric vehicles, including eVTOL aircraft, are critically challenged by the energy density of batteries, which prohibit long-distance tasks and broader applications. Since the takeoff process of eVTOL aircraft demands excessive energy and couples multiple subsystems (such as aerodynamics and propulsion), multidisciplinary analysis and optimization (MDAO) become essential. Conventional MDAO, however, iteratively evaluates high-fidelity simulation models, making the whole process computationally intensive. Surrogates, in lieu of simulation models, empower efficient MDAO with the …
