Although the prospect of computerized homes has a long history, ho/ne automation has never become terribly popular because the benefits are seldom seen to outweigh the costs. One significant cost of an automated home is that someone has to program it to behave appropriately. Typical inhabitants do not want to program simple devices such as VCRs, let alone a much broader range of electronic devi...

We are doing research and development of an intelligent lighting system. In the intelligent lighting system, the algorithm which controls lighting fixtures is important. In this research, we examine how to grasp the position relation between the lighting and the illuminance sensors with sufficient accuracy, and we propose a lighting control algorithm which estimates accurate position relation b...

Accurate assessment of people's preferences for different outdoor lighting applications is increasingly considered important in the development of new urban environments. Here a new method of random environmental walking is proposed to complement current methods of assessing urban lighting applications, such as self-report questionnaires. The procedure involves participants repeatedly walking b...

Lighting design plays a crucial role in indoor lighting design, computer cinematograph and many other applications. Computer-assisted lighting design aims to find a lighting configuration that best approximates the illumination effect specified by designers. In this paper, we present an automatic approach for lighting design, in which discrete and continuous optimization of the lighting configu...

conclusions in lighting conditions, most of t-res was isomerized to the other isomer cis-resveratrol. t-res is unstable in alkali ph and when exposed to light. t-res was quite stable at other conditions, and several freeze-thaw cycles did not have any effect on its stability. results our findings revealed that t-res was quite stable in different temperatures ranging from -70 °c to 25 °c, and ac...
