A Reputation System For Provably-Robust Decision Making In Iot Blockchain Networks, Charles C. Rawlins, Sarangapani Jagannathan, Venkata Sriram Siddhardh Nadendla

Electrical and Computer Engineering Faculty Research & Creative Works

Blockchain systems have been successful in discerning truthful information from interagent interaction amidst possible attackers or conflicts, which is crucial for the completion of nontrivial tasks in distributed networking. However, the state-of-the-art blockchain protocols are limited to resource-rich applications where reliably connected nodes within the network are equipped with significant computing power to run lottery-based proof-of-work (pow) consensus. The purpose of this work is to address these challenges for implementation in a severely resource-constrained distributed network with internet of things (iot) devices. The contribution of this work is a novel lightweight alternative, called weight-based reputation (wbr) scheme, to classify new …

Dyonic Taub-Nut-Ads Spaces: Phase Structures Of All Horizon Geometries, Mohamed Tharwat, Amr Albarqawy, Adel Awad, Esraa Elkhateeb

Faculty Journal Articles

We study phase structures of Lorentzian Dyonic Taub-NUT-AdS spacetimes for different horizon geometries, which could be spherical, flat, or hyperbolic. We check the consistency of our extended thermodynamics approach through satisfying the first law, the Gibbs-Duhem relation, and the generalized Smarr's relation. Although we study the phase structure for the three cases, we give special attention to the flat and hyperbolic cases since they are known to show no phase transitions and were not studied before. Working in a mixed ensemble, we found that the behaviors of the flat and hyperbolic cases are different from those of a charged black …

Predominantly White Teacher Education Programs Are Stifling Black Preservice Students’ Teaching Experience: Now What?, Jasmine N. Wilson

Masters Projects

scholarship theorizes and discusses Black preservice teachers’ experiences in predominantly White teacher education programs as stifling. While many studies have explored ways to improve Black students' experiences in teacher education, few studies have sought to adapt Historically Black Colleges and Universities’ (HBCU) successful strategies to produce and retain Black teachers. In this project I have two goals. My first goal is to highlight the neglect and inequity that Black preservice teachers face in predominantly White teacher education programs. My second goal is to ensure that faculty members in teacher education programs effectively support and prepare Black preservice teachers for long …

Corrosion And Passivation Behavior Of Laser Powder Bed Fusion Produced Ti-6al-4v Under Various Prior Plastic Deformation Strains, P. Qin, L. Y. Chen, Y. J. Liu, S. X. Liang, H. Sun, L. C. Zhang

Research outputs 2022 to 2026

This work investigated the corrosion behavior of LPBF-produced Ti-6Al-4V under varying compression strains in a 3.5 wt% NaCl solution. It identifies that increasing compression strain causes significant alterations in the acicular a'-Ti phase (coarsening, breakage, and further coarsening). Corrosion resistance decreases with higher strains due to deformed a'-Ti phases, leading to increased film growth kinetics (from 0.09× 10−10 cm2/s increase to 12.75 × 10−10 cm2/s). Samples under higher strains (e.g., 32%) exhibit fluctuations in corrosion behavior due to initiated cracks and subsequent crevice corrosion. These findings are vital for understanding LPBF-produced Ti-6Al-4V in applications requiring mechanical strength and corrosion resilience.

From Pumps And Pipes To Data And Discovery: Unifying A New Division, Jeremy Myntti, Megan Mcmillan

Faculty Publications

A reorganization of the Brigham Young University Library in 2020 brought many changes to the library, including the formation of the Metadata and Information Technology (MIT) Division.

An Exploration Of The Effectiveness Of Xanthorrhiza Simplicissima And Its Secondary Alkaloids As Antibiotics Against Staphylococcus Aureus With The Use Of Reserpine, Donald Bothe, Savita Chaurasia

Undergraduate Theses

Xanthorhiza simplicissima is a plant that is steeped in medical history. It has been used for hundreds of years by the Native Americans, and later by the Europeans, of Appalachia for its medicinal properties. One of the most useful medical applications of this plant are its antibiotic properties, as typified by its use as a tea that was consumed to treat mouth sores. These antibiotic properties can be attributed to some of its secondary alkaloids such as berberine, liriodenine, oxyacanthine, and magnoflorine. These compounds have been studied in other systems; however, oxyacanthine and magnoflorine have not been researched in tandem …

Indigenization Of Postsecondary Education Applied Learning Curriculum Development, Gabriel Y. Chung

The Dissertation in Practice at Western University

The Truth and Reconciliation Commission of Canada’s (2015) Calls to Action have awoken Canadian society to the reconciliation. Although there is a growing body of knowledge on the individual topics of Indigenous education, knowledge, and leadership, there is relatively little research bringing together these topics in curriculum development practices in a postsecondary education skilled learning context. My problem of practice (PoP) is one that strives to address a low enrolment of Indigenous adult learners and lower positive outcomes from skilled training programs. Situating this problem from my perspectives as a Canadian-born visible minority Settler on Turtle Island and postsecondary education …
