We have made an initial assessment of the image quality of the WFC3 UVIS channel with its flight detector installed. Point source measurements at four field positions and four wavelengths indicate excellent imaging performance for the UVIS channel, with CEI encircled energy specifications readily achieved.

Background: Today, air pollution is one of the major problems in large cities including Isfahan. Methods: The objective of this study was to investigate the variations of ozone (O3), carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO2), nitrogen oxides (NOx), sulphur dioxide (SO2), and particulate matter (PM10) concentrations in different months at three stations and also to explore ...

Hand-held portable gas detectors often may be configured to have 4, 5, or even 6 different sensors installed by the factory. The sensor selection should be made by the prospective purchaser based on the intended application of the instrument after they take possession of the device. The prospective user needs to convey to the factory such possible applications as Confined Space Entry, HazMat Re...

Based on the Kennaugh-Huynen decomposition, the Target Scattering Vector Model (TSVM) allows to extract four rollinvariant parameters. Those parameters are necessary for an unambiguous description of the target scattering mechanism. The proposed method consists in applying the TSVM prior to the GLRT-LQ detector for the detection of any oriented target.

In models with large extra dimensions, particle collisions with center-of-mass energy larger than the fundamental gravitational scale can generate nonperturbative gravitational objects. Since cosmic rays have been observed with energies above 108 TeV, gravitational effects in the TeV energy range can, in principle, be observed by ultrahigh energy cosmic ray detectors. We consider the interactio...

The basic concept and the status of currently operating ground-based array detectors for VHE gamma-ray astronomy will be presented and compared with imaging air Cherenkov telescopes. Also an outlook of future prospects will be given.

air conditioning is widely applied for the improvement of standard of living in human life. this present investigation focused on the prediction of indoor air quality characteristics of air conditioned car using fuzzy logic algorithm. the conditioned space was selected and the experiments were planned as per design of experiments to study the effect of human load, fresh air supply and air veloc...
