Numerical techniques to find optimal input parameters for achieving mean particles’ temperature and axial velocity in atmospheric plasma spray process
(Nature Research, 2020)We numerically find values of four process input parameters, namely, the argon flow rate, the hydrogen flow rate, the powder feed rate, and the current, that yield the desired mean particles’ temperature and the mean ... -
A Novel Method and Exoskeletons for Whole-Arm Gravity Compensation
(IEEE, 2020-08-17)We present a new method for providing gravity compensation to a human or robot arm. This method allows the arm to be supported in any orientation, and also allows for the support of a load held in the hand. We accomplish ... -
An elbow exoskeleton for haptic feedback made with a direct drive hobby motor
(Elsevier, 2020)A direct drive motor is one of the simplest mechanisms that can be used to move a mechanical joint. In particular, a brushless direct current (BLDC) motor with no gearing produces a low parasitic torque due to its ... -
Survival of MS2 and Φ6 viruses in droplets as a function of relative humidity, pH, and salt, protein, and surfactant concentrations
(PLOS, 2020-12-08)The survival of viruses in droplets is known to depend on droplets’ chemical composition, which may vary in respiratory fluid between individuals and over the course of disease. This relationship is also important for ... -
Thermal expansion driven indentation stress-strain system
(1992-07-28)Disclosed is a method and apparatus of indentation testing of variable types of specimens which includes mounting an indenter member onto a thermally expandable member, mounting the specimen to be tested on a pedestal, ... -
Evaluation of Seismic Vulnerability of Hospitals in the Tehran Metropolitan Area
(MDPI, 2021-02-05)The Tehran metropolitan area is extremely vulnerable to earthquakes due to the location of its active faults and its dense population. Assessing the probable damage of a high magnitude earthquake on buildings and facilities ... -
Multi‑level modeling with nonlinear movement metrics to classify self‑injurious behaviors in autism spectrum disorder
(Nature Research, 2020)Self-injurious behavior (SIB) is among the most dangerous concerns in autism spectrum disorder (ASD), often requiring detailed and tedious management methods. Sensor-based behavioral monitoring could address the limitations ... -
Systems and Methods for Monitoring Eye Health
(2020-10-20)Systems and methods for monitoring eye health. The systems and methods monitor eye health by measuring scleral strain by way of an implantable monitor, a wearable monitor configured in eyeglasses, or an external monitor ... -
Research Methods for the Capstone to Work (C2W) Project
(2021-02-24)This report details the research methods (sites, sample, data collection instruments, data analysis, codebook, data profiles) for the NSF funded project "From School to Work: Understanding the Transition from Capstone ... -
Simultaneous Observations of Geoelectric and Geomagnetic Fields Produced by Magnetospheric ULF Waves
(2020-09-28)Geomagnetic perturbations (B-GEO) related to magnetospheric ultralow frequency (ULF) waves induce electric fields within the conductive Earth-geoelectric fields (E-GEO)-that in turn drive geomagnetically induced currents. ... -
Review and simulation of passive seismic tomography in block cave mining
(Australian Centre for Geomechanics, Perth, 2018)Seismic tomography methods are progressing in crustal seismology and at the smaller mining scale to recognise highly stressed or fracture-prone areas. Velocity variations measured by seismic tomography represent stress ... -
Standard Propagation Channel Models for MIMO Communication Systems
(Hindawi, 2021-02-16)The field of wireless communication networks has witnessed a dramatic change over the last decade due to sophisticated technologies deployed to satisfy various demands peculiar to different data-intensive wireless applications. ... -
A conceptual protocol for integrating multiple parameters for risk assessment due to induced seismicity in a deep mine
(2020-01-01)Typically, the time-dependent b-value has been shown to decrease prior to the occurrence of a higher-magnitude event, thus providing a possible indicator of the timing of a significant event. The Energy Index relates seismic ... -
Addressing the Contribution of Indirect Potable Reuse to Inland Freshwater Salinization
(2021-02-02)Inland freshwater salinity is rising worldwide, a phenomenon called the freshwater salinization syndrome (FSS). We investigate a potential conflict between managing the FSS and indirect potable reuse, the practice of ... -
Re‐envisioning stormwater infrastructure for ultrahazardous flooding
(Wiley, 2020-03)Ultrahazardous flooding (UHF) occurs on low relief topography at the foot of mountain catchments and is characterized by rapid-onset, high-velocity flood flows, large fluxes of sediment and debris, and unpredictable flow ... -
Impossibility of coin flipping in generalized probabilistic theories via discretizations of semi-infinite programs
(2020-10-23)Coin flipping is a fundamental cryptographic task where spatially separated Alice and Bob wish to generate a fair coin flip over a communication channel. It is known that ideal coin flipping is impossible in both classical ... -
Conductance Model for Extreme Events: Impact of Auroral Conductance on Space Weather Forecasts
(2020-09-27)Ionospheric conductance is a crucial factor in regulating the closure of magnetospheric field-aligned currents through the ionosphere as Hall and Pedersen currents. Despite its importance in predictive investigations of ... -
Unifying Advective and Diffusive Descriptions of Bedform Pumping in the Benthic Biolayer of Streams
(2020-09-01)Many water quality and ecosystem functions performed by streams occur in the benthic biolayer, the biologically active upper (similar to 5 cm) layer of the streambed. Solute transport through the benthic biolayer is ... -
A One-Dimensional Model for Turbulent Mixing in the Benthic Biolayer of Stream and Coastal Sediments
(2020-12)In this paper, we develop and validate a rigorous modeling framework, based on Duhamel's Theorem, for the unsteady one-dimensional vertical transport of a solute across a flat sediment-water interface (SWI) and through the ... -
