The color of an image may be affected by many factors such as illumination, complex and multispectral reflections, and even the acquisition device. Especially in outdoor scenes, these conditions cannot be controlled. In order to use the information of an image, the latter must present the information as closer as possible to the original scene. Sometimes images are affected by a dominant color ...

Abstract Background Despite improvement in safety of plasma transfusion some virus transmission still remains a problem. So as World Health Organization (WHO) recommends, many countries developed Pathogen Reduction Technologies (PRT) to inactivate pathogens, in plasma components. The Methylene Blue (MB) based methods is one of the most universal one. The purpose of this research was, produce...

  Background and aims: Adequate lighting in work environments can increase productivity and concentration and reduce fatigue. Light and illumination studies have been done mainly in industrial environments, and public or administrative environments were less under consideration. The aim of this study was to evaluate the ultraviolet radiation and illumination level at Kerman Medical Sciences Uni...

Skylights or light wells are an integral part of the design of low- and high-depth buildings. The design of these skylights in different areas is based on specific criteria. According to Hamedan's criteria, only the dimensions of these skylights and the ratio of skylight area to height of the skylight are enough to design skylights. The purpose of this study was to evaluate the accuracy of sk...

This paper has been utilizing the simultaneous ThermoGravimetric analysis and Differential Scanning Calorimetry (TG–DSC) to investigate the thermal decomposition of magnesium-sodium nitrate pyrotechnic composition based HTPB resin. The thermal behaviors of different samples with various fuel-oxidizer ratio contents were determined. Decomposition kinetic was investigated by evaluating the in...

The effect of optical illumination on DC and dynamic performance of Si1-xGex based double drift region (DDR) (p+pnn+) IMPATT diode operating at W-Band is investigated and compared with its Silicon counterpart. Top Mounted (TM) and Flip Chip (FC) structures are chosen and the composition of photocurrent is altered by shining light on the p+ side and n+ side of the device through optical windows....
