Gamma-ray polarimetry is a new powerful tool to study the processes responsible for the emission from astrophysical sources and the environments in which this emission takes place. Few successful polarimetric measurements have however been performed thus far in the gamma-ray energy band due to the difficulties involved. POLAR is a dedicated polarimeter designed to perform high precision measurements...
A method for the determination of saturation magnetization of grain-oriented silicon steel sheets using the super-conducting magnet and the magnet field measurement instrument is suggested. An example is also given to illustrate the method.
The present study investigates the visual ergonomics of different instrument shapes and colors based on event-related-potential. Two color combinations of the dial scales were used, which were named G-dials and B-dials respectively under each dial shape. Fifteen participants took part in the experiments. The two groups of dials were used as target stimuli respectively with P300 recorded. The participants...
The sources of ionospheric forcing are from above (solar and magnetospheric forces), internal (chemistry, local neutral dynamics), and from below (lower atmosphere). In this work we review the observed ion-neutral coupling effects at equatorial and low latitudes during large meteorological events called sudden stratospheric warming (SSW). Research in this direction has been accelerated in recent years...
As service organizations have realized that service is fundamental to establish their competitive advantage, waiting time management has been a subject of much service research. This study aims to explore how waiting time impact on tourist satisfaction in theme parks. The findings from a survey of 102 tourists from the theme park in Shenzhen City in China confirm that perceived waiting time, waiting...
