Application Of Surge Arrester In Limiting Voltage Stress At Direct Current Breaker, Mohammadamin Moghbeli, Shahab Mehraeen, Sudipta Sen

Faculty Publications

Hybrid DC circuit breakers combine mechanical switches with a redirecting current path, typically controlled by power electronic devices, to prevent arcing during switch contact separation. The authors’ past work includes a bipolar hybrid DC circuit breaker that effectively redirects the fault current and returns it to the source. This reduces arcing between the mechanical breaker’s contacts and prevents large voltage overshoots across them. However, the breaker’s performance declines as the upstream line inductance increases, causing overvoltage. This work introduces a modification to the originally proposed hybrid DC breaker to make it suitable to use anywhere along DC grid lines. By …

Faculty Publications

With standard T6 heat treatments, precipitate-hardened alloys such as Al7075 and Al6061 fabricated using Additive Friction Stir Deposition (AFSD) method restore to noticeablely different peak mechanical properties. Previous research observed similar results but did not provide a viable solution. This study proposes a new processing strategy, namely enhanced plastic deformation by subjecting the Al7075 feedstock to annealed softening treatments. Specifically, by annealing the standard T651-Al7075 feedstock and deposition substrate (179 HV), their Microhardness were first degraded to its lowest state (80 HV), which is called a Soft-to-Soft system. For the Soft-to-Soft system subjected to AFSD, after undergoing appropriate T6 heat …

An Intelligent Impulsive Noise Mitigation With Deep Learning Method, Guo Yang, Yuwen Qian, Zikun Wang, Xiangwei Zhou, Wen Wu

Faculty Publications

To enable message transmission among sensors and equipment, power line communication (PLC) is a widely adopted smart grid. However, due to the occurrence of impulsive noise (IN), reliable transmissions over PLC channels in the smart grid are challenging. Therefore, in this paper, we propose an adaptive noise mitigation scheme to clip the IN with the sliding window-based method, where the altitude of the received signal in the current time slots is obtained by computing the average altitude of signals in the previous and next time slots. To detect the states of IN and dynamically estimate the power threshold of signals …

High-Mast Tower Foundation – Phase Ii, Ammar Al Maabreh, Abdelrahman Awawdeh, Marc Maguire, Jay Puckett, Brandon Kreiling

Nebraska Department of Transportation: Research Reports

Challenge: High-mast luminaire supports used in the US transportation sector are typically steel poles that are attached to a baseplate via a butt or socket weld. Many have failed primarily due to fatigue cracking at the weld toe. Significant research in the US improved the fatigue performance of these structures; however, failures still occur due to high-cycle cracking at the weld toes, or at other fatigue-prone details. Additionally, poles are failing in moderate winds that create galloping. Galloping is an aerodynamic phenomenon where the wind excitation frequency matches the pole’s natural frequency creating resonance. The top amplitudes are many times …

Enhancement Of High-Density Lipoprotein-Associated Protease Inhibitor Activity Prevents Atherosclerosis Progression, Maura Mobilia, Alexander A. Karakashian, Khaga R. Neupane, Olivia Hage, Callie Whitus, Abigail Carter, Clairity Voy, Lance A. Johnson, Gregory A. Graf, Scott M. Gordon

Saha Cardiovascular Research Center Faculty Publications

Background and aims: Inflammatory cells within atherosclerotic lesions secrete proteolytic enzymes that contribute to lesion progression and destabilization, increasing the risk for an acute cardiovascular event. Elastase is a serine protease, secreted by macrophages and neutrophils, that may contribute to the development of unstable plaque. We previously reported interaction of endogenous protease-inhibitor proteins with high- density lipoprotein (HDL), including alpha-1-antitrypsin, an inhibitor of elastase. These findings support a potential role for HDL as a modulator of protease activity. In this study, we test the hypothesis that enhancement of HDL-associated elastase inhibitor activity is protective against atherosclerotic lesion progression.

Methods: We …

Faculty Publications

This paper presents a hermitic fiber sensor packaging technique that enables fiber sensors to be embedded in energy systems for performing multi-parameter measurements in high-temperature and strong radiation environments. A high-temperature stable Intrinsic Fabry–Perot interferometer (IFPI) array, inscribed by a femtosecond laser direct writing scheme, is used to measure both temperature and pressure induced strain changes. To address the large disparity in thermo-expansion coefficients (TECs) between silica fibers and metal parts, glass sealants with TEC between silica optical fibers and metals were used to hermetically seal optical fiber sensors inside stainless steel metal tubes. The hermetically sealed package is validated …

Geothermo-Mechanical Alterations Due To Heat Energy Extraction In Enhanced Geothermal Systems: Overview And Prospective Directions, Mary C. Ngoma, Oladoyin Kolawole, Olufemi Olorode

Faculty Publications

Geothermal energy from deep underground (or geological) formations, with or without its combination with carbon capture and storage (CCS), can be a key technology to mitigate anthropogenic greenhouse gas emissions and meet the 2050 net-zero carbon emission target. Geothermal resources in low-permeability and medium- and high-temperature reservoirs in sedimentary sequence require hydraulic stimulation for enhanced geothermal systems (EGS). However, fluid migration for geothermal energy in EGS or with potential CO2 storage in a CO2-EGS are both dependent on the in situ flow pathway network created by induced fluid injection. These thermo-mechanical interactions can be complex and induce varying alterations in …

Right Lung Hypoplasia Associated With Polysplenia: A Case Report And Literature Review, Rayyan M. Almusally

Saudi Medical Journal

Abstract Pulmonary agenesis is a very rare congenital abnormality that can be missed in a routine radiographic examination, which delays diagnosis until adulthood. It can be associated with other congenital malformations, such as valvular heart disease and gastrointestinal organ abnormalities. Computed tomography (CT) is a useful modality for its better delineation of pulmonary and vascular structures. The reported case here is for an adult male who presented with dextroposition of the heart and was found to have a unilobed right lung associated with polysplenia. This has not been previously reported in the literature.

Effects Of Oxycodone On Placental Lineages: Evidence From The Transcriptome Profile Of Mouse Trophoblast Giant Cells, Zhen Lyua, Jessica A. Kinkadeb, Nathan J. Bivens, R. Michael Roberts, Trupti Joshi, Cheryl S. Rosenfeld

Biomedical Sciences

Pregnant women are often prescribed or abuse opioid drugs. The placenta is likely the key to understanding how opioids cause adverse pregnancy outcomes. Maternal oxycodone (OXY) exposure of pregnant mice leads to disturbances in the layer of invasive parietal trophoblast giant cells (pTGC) that forms the interface between the placenta and uterus. These cells are analogous to extravillous trophoblasts of the human placenta. They are crucial to coordinating the metabolic needs of the conceptus with those of the mother and are primary participants in the placenta–brain axis. Their large nuclear size, however, has precluded both single- cell (sc) and single- …

Child-Taking, Diane Marie Amann

Michigan Journal of International Law

A ruling group at times takes certain children out of their community and then tries to remake them in its image. It tries to rid the child of undesired differences, in ethnicity or nationality, religion or politics, race or ancestry, culture or class. There are too many examples: the colonialist residential schools that forced settler cultures on Indigenous children; the military juntas that kidnapped dissidents’ children; and today’s reports of abductions amid crises like that in Syria. Too often nothing is done, and the children are lost. But that may be changing, as the International Criminal Court (“ICC”) is seeking …
