Thermo-mechanical simulation of underwater friction stir welding of low carbon steel
(MDPI, 2021-08-30)This article investigates the flow of materials and weld formation during underwater friction stir welding (UFSW) of low carbon steel. A thermo-mechanical model is used to understand the relation between frictional heat ... -
Secret sharing from correlated Gaussian random variables and public communication
(IEEE, 2021-04-11)We study a secret sharing problem, where a dealer distributes shares of a secret among a set of participants under the constraints that (i) authorized sets of users can recover the secret by pooling their shares, (ii) ... -
Pairwise oblivious transfer
(IEEE, 2021-04-11)We consider oblivious transfer between one client and two non-colluding servers that store independent contents. The client requests one file from each server such that (i) the servers do not learn the file selection of ... -
Optimization of electric vehicle charging schedule using distributed network computing
(IEEE, 2021-04-11)The significant growth in the number of electric vehicles indicates an increased demand on the power distribution system, specifically on the low-voltage residential network. Without a well-organized schedule for charging ... -
Teaching protective relaying using a portable relay training laboratory
(IEEE, 2021-04-11)This paper presents an original portable protective relay training laboratory aimed at teaching power systems students protective relaying to make them “Ready-to-Go Engineers” for working in the power systems industry. The ... -
Demand side management for residential consumers considering distribution system requirements
(IEEE, 2021-04-11)One of the focus areas of the smart-grid initiative is the residential level demand response. Recent surveys have analyzed price-responsive demand response optimization, mathematical modeling of demand response, responsive ... -
Differentially-private federated learning with long-term budget constraints using online Lagrangian descent
(IEEE, 2021-05-10)This paper addresses the problem of time-varying data distribution in a fully decentralized federated learning setting with budget constraints. Most existing work cover only fixed data distribution in the centralized ... -
Wheelchair-mounted upper limb robotic exoskeleton with adaptive controller for activities of daily living
(MDPI, 2021-08-26)Neuro-muscular disorders and diseases such as cerebral palsy and Duchenne Muscular Dystrophy can severely limit a person’s ability to perform activities of daily living (ADL). Exoskeletons can provide an active or passive ... -
Uncertain gain and time-delay control of 300-kW SOFC-GT
(ASME, 2021-08-18)This paper presents a Proportional Integral Derivative (PID) controller design with the presence of an uncertain internal gain and additional time delay in the forward path of a 300 kW Solid Oxide Fuel Cell-Gas Turbine ... -
Effects of FSW tool plunge depth on properties of an Al-Mg-Si alloy T-joint: Thermomechanical modeling and experimental evaluation
(MDPI, 2021-08-23)One of the main challenging issues in friction stir welding (FSW) of stiffened structures is maximizing skin and flange mixing. Among the various parameters in FSW that can affect the quality of mixing between skin and ... -
Effect of flaperons on a biplane configuration
(Wichita State University, 1994-05)The use of full span flaperons on low speed biplane configurations i~ a unique synergistic concept that has yet to be evaluated. The well-executed biplane configuration is useful for performing low speed aerobatics, ... -
Impact of building systems usage on indoor particulate matter $(PM_{2.5})$ concentration in residential buildings
(Wichita State University, 2021-07)Indoor air quality (IAQ) is essential because people spend up to 90% of their time indoors. There are various sources of indoor air pollutants, including combustion, building materials, and outdoor air pollution. Particulate ... -
Exploration of integrated solar supercapacitor devices for solar energy conversion and storage
(Wichita State University, 2021-07)As the world’s population is growing and moving towards the modernization, the demand of energy is gradually increasing every day. At the current rate of consumption of energy, the demand is to be increased by 65% by the ... -
The impact of fluid shear stress on the morphology of human dermal microvascular endothelial cells
(Wichita State University, 2021-07)As blood flows through blood vessels, the fluid exerts a shear stress on the endothelial cells that line the vasculature. The current perception in the literature is that all endothelial cells will align and elongate in ... -
Analysis of wayfarer side, front and rear impact with a lightweight pickup truck at center and front corners
(Wichita State University, 2021-07)Wayfarer injuries and fatalities in the United States has taken an uprise in the past few decades. According to the data estimated by National Highway Traffic Safety Association (NHTSA), there are severe pedestrian injuries ... -
Design and implementation of a remote assistance application for persons with visual impairments
(Wichita State University, 2021-07)Individuals who are Blind or Visually Impaired (BVI) confront numerous problems when completing regular duties or exploring new places. Getting assistance from strangers is not always desirable in such situations. With ... -
Computational fluid dynamics and fluid structure interaction analysis on the use of inflatable wing structures
