Measurement of plasma flows using Mach probe arrays
A rectangular array of three-dimensional Mach probes is constructed and installed in the plasma vessel of the Versatile Toroidal Facility (VTF) at MIT in order to measure ion flow velocity on the cross section of the VTF. The probes are tested using well-characterized toroidal plasma 'blobs' in …

Measurement of Liquid Film in Annular Flow Using X-Ray Densitometry
… measurement techniques such as impedance probes may compromise accuracy by directly contacting and potentially disturbing the flow. Non-intrusive measurement methods are needed to provide more reliable film thickness data for improved reactor safety calculations in Boiling Water Reactors …

Analysis of acoustic communication channel characterization data in the surf zone
… water and breaking waves. In analyzing the data, several questions arose. The majority of the acoustic channel probe data was corrupted by crosstalk in the receiver array cable. This thesis investigates methods to correct for the effects of the crosstalk, to attempt to recover the channel …

Soil compaction caused by timber harvesting in central Appalachian hardwood forests
… condition was recorded using a nuclear density probe. Data were analyzed statistically to determine the effect of operational variables on soil impacts. Results indicate that timber harvesting does affect the soil compaction levels in the woods, as well as along skid roads. Soil compaction also …

Evaluating the Effects of Timed Practice on Reading Endurance: A Comparison of One-Minute and Three-Minute Practice Conditions
… This study used a counterbalanced multiple probe design to compare the effects of two reading practices on reading endurance of six second grade regular education students. The results indicated that the frequency of words read correctly increased in level and trend when a passage was …

Fundamental Study and Development of a Hydrogen Pellet Accelerator Using a Fuseless Two-Stage Plasma-Arc-Driven Electromagnetic Railgun
… velocities of 800 m/s. Streak-camera and current-probe data showed that the plasma-arc armature moves at a velocity proportional to the railgun current, I, and not to the often-quoted I('2). Insight to this I-dependence has been gained through the use of streak photography and current probes for …

Instrument development and plasma measurements on a 200-watt Hall thruster plume
… plume models. The instruments included a Faraday probe to measure current density, a hot emissive probe to measure plasma potential, and a cold Langmuir probe to measure electron temperature and electron density. Plasma measurements consisted of studying facility and thruster effects on the plume. …
