Context. Current generation millimeter wavelength detectors suffer from scaling limits imposed by complex cryogenic readout electronics. These instruments typically employ multiplexing ratios well below a hundred. To achieve multiplexing ratios greater than a thousand, it is imperative to investigate technologies that intrinsically incorporate strong multiplexing. One possible solution is the k...

A new proposal for Cartan contortion detection based on the resonant gravitational wave (GW) detector in teleparallel spacetime is considered.It is shown that Cartan contortion is proportional to the inverse of the damping time of the resonant detector.Actually the contortion acts as a damping force for the GW.A contortion of the order 10 −29 s −1 is obtained by using the data of present resona...

critical thinking ability has an important role in education. accordingly, scholars around the world are searching for new ways for teaching and improving students critical thinking ability. in line with the studies in efl contexts supporting the positive relationship between critical thinking and writing performances, this study investigated the differential effects of halverson’s critical thi...

We report on the manufacture of a first batch of approximately 2,000 Gas Electron Multipliers (GEMs) using 3M’s fully automated roll to roll flexible circuit production line. This process allows low-cost, reproducible fabrication of a high volume of GEMs of dimensions up to 30×30 cm. First tests indicate that the resulting GEMs have optimal properties as radiation detectors. Production techniqu...

In the context of multimedia data analysis, it is often necessary to understand what happens in a scene, which can rely on detecting and tracking the different moving objects and by comparing their positions at a given time with their environment. In order to model the environment or the scene background, we consider straight lines as appropriate features. In this paper, we compare some classic...

Introduction: Radon is a colorless inert gas which decay products are the main component of natural radioactive elements that are naturally produced in under layers of earth crust by decay of radium and uranium. It enters through buildings via gaps and cracks. Radon gas decay products like alpha particle can increase the incidence of lung cancer in human. Since every person sp...

Measuring Soft X-Ray (SXR) radiation [0.1 keV; 15 keV] in tokamaks is a standard way of extracting valuable information on the particle transport and magnetohydrodynamic activity. Generally, the analysis is performed with detectors positioned close to the plasma for a direct line of sight. A burning plasma, like the ITER deuterium-tritium phase, is too harsh an environment to permit the use of ...

The Oriented Scintillation Spectrometer Experiment (OSSE) on the Arthur Holly ComptonGammaRay Observatory satellite uses four actively-shielded NaI(Tl)-CsI(Na) phoswich detectors to provide gamma-ray line and continuum detection capability in the 0:05 10 MeV energy range. The instrument includes secondary capabilities for gamma-ray and neutron detection between 10 and 250 MeV. The detectors hav...

The application of ultraviolet absorption detector (UV) and circular dichroism (CD) detectors in series in HPLC systems has been increased in recent years. In this work, an effective method to determine the enantiomer concentration on line in chiral drugs was explored. Ibuprofen (IBP) racemate was applied. The total concentration and concentration difference of S-(+)-IBP and R-(-)-IBP were obta...
