In situ calibration for load cells in bipedal 3D printed robot utilizing Computer-Aided Design model
Load cells are very important components in a robot system. They help the robot to get feedback from the environment around it and generate control signals accordingly. However, like every other sensor, load cells need to be calibrated over time to maintain their accuracy and precision. In the …

Toward model-free and reference-free quantitative ultrasound
… (QUS) techniques rely on a reference or a calibration signal to obtain system-independent ultrasonic scattering parameters. Adoption of QUS clinically has been hindered by (1) the need to limit clinical ultrasonic scanner settings to account for a finite number of calibration signals or (2) …

Design and in situ testing of a piezometer system to measure earthquake -induced pore -pressure changes
<p>Pore pressure changes have been measured in fine sand deposits that are known to have liquefied during earthquakes. Some of the measured signals have not been similar to what was expected during earthquake-induced liquefaction. Using artificially generated signals, several investigators have …

Evaluating the Use of TROPICS Pathfinder Observations for Lunar Calibration
Traditional two-point in-situ calibration systems for microwave radiometers use large, on-board hot targets [12]. Small satellites such as CubeSats, however, are unable to house these hot targets due to SWaP constraints. Instead, CubeSat radiometers such as the TROPICS Pathfinder use noise diodes …

An improved method for measuring the absolute DD neutron yield and calibrating neutron time-of-flight detectors in inertial confinement fusion experiments
Since the establishment of nuclear physics in the early 1900's and the development of the hydrogen bomb in the 1950's, inertial confinement fusion (ICF) has been an important field in physics. Funded largely though the U.S. National Nuclear Security Agency (NNSA), the Laboratory for Laser …

Non-invasive monitoring of water and solute fluxes in a cropped soil
Although the influence of root water uptake on solute transport is commonly recognized as important, it has barely been studied throughout the literature. However, plants take up a big amount of the infiltrating water and therefore they influence water flow patterns in the soil and concurrently …

Tools and methods for the quality assurance of force platforms in human movement analysis
… the abilities of a subject to stand or to walk. In the field of HMA, tests are daily performed in research laboratories, hospitals and clinics, aiming to diagnose a disease, distinguish between disease entities, monitor the progress of a treatment and predict the outcome of an intervention [Brand …

Lower Hybrid Current Drive on Alcator C-Mod : measurements with an upgraded MSE diagnostic and comparisons to simulation
Lower Hybrid Current Drive (LHCD) is a promising technique to sustain tokamak plasmas and provide control over the current profile--two important capabilities required for the development of tokamak fusion reactors. Upgraded measurement capabilities on the Alcator C-Mod Tokamak create a unique …

Thermographic particle image velocimetry: from phosphorescence to incandescence
Thermographic PIV is a promising technique that enables simultaneous temperature and velocity imaging in flows with intentional seeded phosphor particles. This is highly attractive to researchers in fluid mechanics and combustion, as it directly visualizes the heat and mass transfer process in …
