Artificial Intelligence-Based Power System Stabilizers For Frequency Stability Enhancement In Multi-Machine Power Systems, Aliyu Sabo, Noor Izzri Abdul Wahab, Mohammad Lutfi Othman, Mai Zurwatul Ahlam Mohd Jaffar, Hakan Acikgoz, Hamed Nafisi, Hossein Shahinzadeh

Articles

Low frequency oscillations (LFOs) occur in a system of interconnected generators connected by weak interconnection. A power system stabilizer (PSS) is commonly used to improve the capacity of the power system dampening. Under a variety of operating conditions, traditional PSSs fail to deliver superior damping. To address this issue, a Farmland Fertility Algorithm (FFA-PSSs controller) was used to solve an optimization problem for optimal design of PSSs system parameters, and its performance efficiency was compared to GA and PSO-based PSSs controllers. In addition to PSS, flexible current transmission (FACTS) devices are widely used. PSSs controllers and FACTS devices are frequently …

Domestic Terrorist Acts As Cultural Texts: A Pentadic Analysis, A. J. Grant, Guy Philbin

Journal of Hate Studies

Former British Prime Minister Margaret Thatcher once said that publicity is the oxygen of terrorism. It is our position that mass-mediated terrorism, white supremacy, and doctrines of racial superiority that justify discrimination, segregation, domination, and even extermination of persons of color should be deprived of the oxygen of publicity. At the same time, we believe that analysis, discussion, confrontation, and condemnation of terrorism and hateful ideologies is painful but necessary. The hate speech and radical ideologies of today’s web-based terrorists reach far beyond traditional means of communication. The purpose of this paper is to use Kenneth Burke’s pentad to analyze …

Optimal Container Migration For Mobile Edge Computing: Algorithm, System Design And Implementation, Taewoon Kim, Motassem Al-Tarazi, Jenn-Wei Lin, Wooyeol Choi

School of Computing: Faculty Publications

Edge computing is a promising alternative to cloud computing for offloading computationally heavy tasks from resource-constrained mobile user devices. Placed at the edge of the network, edge computing is particularly advantageous to delay-limited applications for having a short distance to end- users. However, when a mobile user moves away from the service coverage of the associated edge server, the advantage gradually vanishes, increasing response time. Although service migration has been studied to address this problem focusing on minimizing the service downtime, both zero-downtime and the amount of traffic generated as a result of migration need further study. In this paper, …

Princess, Hoss Wheeler

Theses

Princess takes place in a world where eyeballs stretch out of people’s heads like prehensile limbs. The film follows a father, Franklin, who is seen in his home wearing a dress. He covers himself in a long trench coat before leaving the house. As he gets into a cab, Franklin ushers the driver to move quickly, but before too long the cab gets stuck in traffic. This leaves Franklin no choice but to get out and walk. When he exits the cab, his coat gets stuck in the door and rips as he tries to pull it free. The dress …

Building Techniques Of Multi-Subconductor Transmission Lines., Reda El-Dewieny

Mansoura Engineering Journal

A great number of transmission lines in which each phase consists of multi-subconductors are now present in many practical systems. This paper introduces three different bundling techniques which can be used effectively to obtain the parameters of such lines in terms of phase quantities. Examples are given to illustrate the application of these techniques. A method for eliminating the earth wire (s) while preserving its effect, based on the well known matrix reduction, is also introduced. A general comparison between the bundling methods is given and it is shown that, one of these methods require more computation time than the …

The Paideia Program Is Worth Another Look, Jessica Richardi

Journal of Educational Research and Practice

Educational opportunity is unequally distributed in the United States, most notably by race and economic status. Commonly practiced in K–12 schools across the country, tracking and ability grouping serve to exacerbate those existing inequities. Recent renewed activism for racial and economic justice, coupled with concerns over learning loss due to COVID-19 school closures, makes this an ideal time for educators to reconsider a formerly well-known and ambitious whole-school reform system called the Paideia Program. The system itself is described and a comprehensive review of research and literature follows. This review demonstrates Paideia’s potential to improve educational outcomes and thus help …

Iwamoto, Danielle Germann, Joanna Reszeć, Natalia Marcińczyk, Robert J. Carroll, Paul A. Janmey, J. M. Schwarz, Robert Bucki, Alison E. Patteson

Physics - All Scholarship

Infection of human cells by pathogens, including SARS-CoV-2, typically proceeds by cell surface binding to a crucial receptor. The primary receptor for SARS-CoV-2 is the angiotensin-converting enzyme 2 (ACE2), yet new studies reveal the importance of additional extracellular co-receptors that mediate binding and host cell invasion by SARS-CoV-2. Vimentin is an intermediate filament protein that is increasingly recognized as being present on the extracellular surface of a subset of cell types, where it can bind to and facilitate pathogens’ cellular uptake. Biophysical and cell infection studies are done to determine whether vimentin might bind SARS-CoV-2 and facilitate its uptake. Dynamic …

Hiv/Aids After The Crisis: The Evolution Of An Epidemic, Emma Paras

Honors Projects

HIV and AIDS has affected the world for over four decades. In the past, a positive HIV diagnosis could very well be a death sentence, as well as signal that an individual was a social outcast. In the past ten years, however, treatments for HIV/AIDS allow a person to live a long and relatively healthy life. In addition to examining current and future trends in HIV treatment, this paper will also discuss how the virus affects different regions of the world. Particularly in certain parts of Africa, HIV/AIDS remains deadly for many who don’t have proper access to health care …

Chert Formation At Iodp Site U1521 As A Proxy For Variations In Marine Geochemistry At The Onset Of The Miocene Climate Optimum, Finlay T. Mcelmeel

Honors Capstones

The goal of International Ocean Discovery Program (IODP) Expedition 374 in the Ross Sea, Antarctica was to collect marine sediment drill cores that would demonstrate the changes in the Antarctic Ice Sheets mass balance during times of Earth history when global temperatures and atmospheric CO2 were higher than today. Intervals such as the Miocene Climatic Optimum (MCO; ~17-14.5 million years ago) provide insights into what a future world could look like (Shevenell et al., 2004; Levy et al., 2016). Ice-proximal records from the near-Antarctic coast, such as those collected during IODP Exp 374, may hold critical information to understanding far-reaching …

Understanding The Lack Of Under-Represented Racial And Ethnic Minorities In Ophthalmology, Emily K. Tam, Michael Harrell, Nicole H. Siegel

Journal of Academic Ophthalmology

To adequately address the racial and ethnic disparities in eye care for our increasingly diverse society there needs to be a significant increase in physicians from under-represented minority groups (URMs) who pursue careers in ophthalmology. Studies have shown that patient–physician racial congruence tends to improve patient satisfaction and medical compliance.[1] However, there are significant racial and ethnic disparities that exist within medicine as a whole and, more specifically, within the field of ophthalmology.[2] One way to address this gap is to diversify the physician workforce by increasing the number of physicians from URMs.[2] URM is defined by membership in certain …

An Analysis Of The Research Productivity & Research Interests Of Library And Information Science Department Of Panjab University In Zenodo Community, Subhajit Panda, Dr. Atasi Sinhababu

Library Philosophy and Practice (e-journal)

The crisis in open access scholarly communications leads to several initiatives promoting the development of open access repositories. It reduces the repetition of research studies by minimising the cost of access and encouraging the reuse of research data. But at the same time, the contributor researchers are also concerned about the long term preservation, meta-descriptions and citation support of their research publication shard in open access repositories. Zenodo, as an open access repository, supports a wider variety of use cases, and many of them implement minimal control on the data uploaded by users. The present study discusses the research output …

Discovery Of Phosphotyrosine-Binding Oligopeptides With Supramolecular Target Selectivity, Ana S. Pina, Leonor Morgado, Krystyna L. Duncan, Sara Carvalho, Henrique F. Carvalho, Armenio J. M. Barbosa, Beatriz De P. Mariz, Ines P. Moreira, Daniela Kalafatovic, Bruno M. Morais Faustino, Vishal Narang, Tong Wang, Charalampos G. Pappas, Isabel Ferreira, A. Cecılia A. Roque, Rein V. Ulijn

Advanced Science Research Center

We demonstrate phage-display screening on self-assembled ligands that enables the identification of oligopeptides that selectively bind dynamic supramolecular targets over their unassembled counterparts. The concept is demonstrated through panning of a phage-display oligopeptide library against supramolecular tyrosine-phosphate ligands using 9-fluorenylmethoxycarbonyl-phenylalanine-tyrosine-phosphate (Fmoc-FpY) micellar aggregates as targets. The 14 selected peptides showed no sequence consensus but were enriched in cationic and proline residues. The lead peptide, KVYFSIPWRVPM-NH2 (P7) was found to bind to the Fmoc-FpY ligand exclusively in its self-assembled state with KD = 74 ± 3 μM. Circular dichroism, NMR and molecular dynamics simulations revealed that the peptide interacts with Fmoc-FpY …
