Photogrammetry, cloud storage, virtual reality, and augmented reality to guide radiation measurement planning and visualization process
Localizing a radiation source in an urban environment is a challenge in nuclear nonproliferation and radiation detection. One approach to localize a source is to send a mobile radiation sensor network into an area of interest to collect count rate measurements at many locations in an attempt to …

Atmospheric temperature profile retrievals using 54 and 118-GHz spectral observations from the Proteus Aircraft
… Using radiosondes collected from the Atmospheric Radiation Measurement (ARM) Program, a gain and baseline calibration correction was implemented to improve the accuracy of temperature profile retrievals for a particular day. Sensitivity of the NAST-M data was approximately [plus-minus] 0.5K and …

Experimental investigations on the influence of curvature and materials on near-field thermal radiation
… bimaterial cantilever based near-field thermal radiation measurement setup was an experimental breakthrough in the field of near-field thermal radiation. The setup distinguishes itself from other experimental configurations at that time by allowing a direct measurement of the near-field thermal …

Electromagnetic radiation level detection and monitoring system for triple band GSM signal using calculable antenna factor method
… project is about monitoring electromagnetic (EM) radiation level for mobile frequency range where the system is capable of detecting the level of electromagnetic radiation (in volts/meter) by the receiver antenna (sensors) at the frequencies of 0.9 GHz, 1.8 GHz and 2.1 GHz. The system then …

Analysis of single event transients in arbitrary waveforms using statistical window analysis
… function is demonstrated using the Ionizing Radiation Effects Spectroscopy (IRES) technique to enhance the measurement of transient anomalies within arbitrary waveforms. The IRES filter convolves time data with a sliding window consisting of a moment-generating function. The resulting …

Ionizing radiation effects spectroscopy
… Various stresses, such as exposure to ionizing radiation and extreme temperatures can result in performance degradation, transient anomalies, and hard failures. These issues have become evident in recent years with the increasing interest in the use of commercial-off-the-shelf (COTS) electronics …

Monte Carlo Analysis and Physics Characterization of a Novel Nanoparticle Detector for Medical and Micro-dosimetry Applications
<p>The outcomes for both (i) radiation therapy and (ii) preclinical small animal radio- biology studies are dependent on the delivery of a known quantity of radiation to a specific and intentional location. Adverse effects can result from these procedures if the dose to the target is too high or low, …

Studies of Radiation Effects in Three High Polymers
… of the materials before and after irradiation were measured using an AC electrical dissipation factor technique. From the T<sub>g</sub> data, it was found that the electron radiation at these total doses results in net chain scissioning in Mylar and net crosslinking in Ultem, while …
