SpaceDrones 2.0—Hardware-in-the-Loop Simulation and Validation for Orbital and Deep Space Computer Vision and Machine Learning Tasking Using Free-Flying Drone Platforms
(MDPI, 2022-05-06)The proliferation of reusable space vehicles has fundamentally changed how assets are injected into the low earth orbit and beyond, increasing both the reliability and frequency of launches. Consequently, it has led to the ... -
A Reliable Way to Improve Electrochemical Migration (ECM) Resistance of Nanosilver Paste as a Bonding Material
(MDPI, 2022-05-09)Electrochemical migration (ECM) of sintered nano-Ag could be a serious reliability concern for power devices with high-density packaging. An anti-ECM nano-Ag-SiOx paste was proposed by doping 0.1wt% SiOx ... -
Keeping Our Heads above Water: An Exploratory Study on the Equity Opportunities of Coastal Virginia Wireless Emergency Alerts
(MDPI, 2022-05-08)Economically disadvantaged coastal communities face severe damage and casualties, which can be attributed to storm surges. Excessive amounts of inundation should be considered to a similar level to wind speeds and heavy ... -
Linearly Implicit General Linear Methods
(2021-12-01)Linearly implicit Runge–Kutta methods provide a fitting balance of implicit treat- ment of stiff systems and computational cost. In this paper we extend the class of linearly implicit Runge–Kutta methods to include multi-stage ... -
Physics-informed neural networks for PDE-constrained optimization and control
(2022-05-06)A fundamental problem of science is designing optimal control policies that manipulate a given environment into producing the desired outcome. Control PhysicsInformed Neural Networks simultaneously solve a given system ... -
Benefits of integrated screening and vaccination for infection control
(PLOS, 2022-04-21)Importance: Screening and vaccination are essential in the fight against infectious diseases, but need to be integrated and customized based on community and disease characteristics. Objective: To develop effective ... -
Effects of back-support exoskeleton use on lower limb joint kinematics and kinetics during level walking
(Springer, 2022-04-27)We assessed the effects of using a passive back-support exoskeleton (BSE) on lower limb joint kinematics and kinetics during level walking. Twenty young, healthy participants completed level walking trials while wearing a ... -
Exploratory field testing of passive exoskeletons in several manufacturing environments: perceived usability and user acceptance
(2022-04-22)OCCUPATIONAL APPLICATIONS: Results of the current exploratory study suggest that use of an exoskeleton (EXO) has the potential to be accepted by workers as an intervention in diverse manufacturing environments. Also evident ... -
Bridging cognitive gaps between user and model in interactive dimension reduction
(2021-06)Interactive machine learning (ML) systems are difficult to design because of the "Two Black Boxes" problem that exists at the interface between human and machine. Many algorithms that are used in interactive ML systems are ... -
The environmental footprint of data centers in the United States
(2021-06)Much of the world's data are stored, managed, and distributed by data centers. Data centers require a tremendous amount of energy to operate, accounting for around 1.8% of electricity use in the United States. Large amounts ... -
Effect of straining flow and droplet shape on vaporization rate of liquid fuel droplet
(2020-11-24)This study focuses on the effect of planar straining flow on the vaporization of droplets. This work is motivated by spray combustion in gas turbines where the turbulence inside the combustor leads to the presence of both ... -
Tunneling Nanotubes between Cells Migrating in ECM Mimicking Fibrous Environments
(MDPI, 2022-04-14)Tunneling nanotubes (TNTs) comprise a unique class of actin-rich nanoscale membranous protrusions. They enable long-distance intercellular communication and may play an integral role in tumor formation, progression, and ... -
A Coupled Hydrologic-Economic Modeling Framework for Scenario Analysis
(2021-06-03)To capture the interactions between hydrologic and economic systems necessary for modeling water quality at a sufficient level of spatial detail, we have designed a modular framework that couples an economic model with a ... -
Toward a complete interdisciplinary treatment of scale: Reflexive lessons from socioenvironmental systems modeling
(2021-06-11)The pathways taken throughout any model-based process are undoubtedly influenced by the modeling team involved and the decision choices they make. For interconnected socioenvironmental systems (SES), such teams are ... -
A Direct Ghost Fluid Method for Modeling Explosive Gas and Water Flows
(Hindawi, 2022-04-16)This work presents a Direct Ghost Fluid Method (DGFM) as part of a two-fluid numerical framework suitable to model explosive gas and water flows resulting from underwater explosion (UNDEX). Due to the presence of explosive ... -
Statistical Assessment of Parameters Affecting Firebrand Pile Heat Transfer to Surfaces
(2021-07-07)Firebrands are known to cause ignition of structures far from the primary fire front, resulting in significant damage to structures before firefighting can be attempted. To make structures more resilient to firebrand ... -
UAV-Based Privacy-Preserved Trustworthy Seamless Service Agility for NextG Cellular Networks
(MDPI, 2022-04-02)Next Generation cellular networks are expected to offer better service quality, secure and reliable service provisioning, and more cooperative operation even in unexpected stressful situations. Service provider cooperation ... -
