in addition to attention to natural light as a renewable, costless and environment-friendly source of energy in the late 20th century, numerous studies have been conducted into the effect of natural light on human being’s soul and body and all such studies reiterate the undeniable role of natural lighting on people’s behavior, attitudes, and efficiency. however, in spite of the awareness of the...

The goal of this study was to examine how different light combinations and timing of supplemental lighting affect the vegetative and reproductive responses of pansy (Viola × wittrockiana Rose). The present study was designed as a factorial experiment based on a completely randomized block design with three replications and two factors of timing of supplemental lighting (night-interrupt...

Particulate matter is defined as a mixture of airborne solid particles and liquid droplets that can be inhaled and may cause serious health problems. Such elements are currently measured utilizing air quality monitoring devices that provide information on PM 10 and PM 2.5 levels giving information on pollution levels. However, many difficulties are encountered in the determination of nanosized ...

background: it has been prover that the prevalence of experiencing job related stress is very high among the dentists. this stress can be the result of factors such as poor lightening of dental office and noise. this stress can cause emotional distress and threaten dentists’ physical health and affect the quality of their life. this study is conducted to determine dentists’ professional quality...

Long-term imbalance in light absorption and electron transport by photosystem I (PSI) and photosystem II (PSII) in chloroplasts brings about changes in the composition, structure, and function of thylakoid membranes. The response entails adjustment in the photosystem ratio, which is optimized to help the plant retain a high quantum efficiency of photosynthesis (W.S. Chow, A. Melis, J.M. Anderso...

In the last decade, many methods have been proposed for rendering image-based objects. However, the number and the size of the images required are highly memory demanding. Based on the light field data structure, we propose an improved compression scheme favoring visual appearance and fast random access. Our method relies on vector quantization for preserving access in constant time. 2D Boundin...

Todays fixed-cycle traffic signaling is highly suboptimal and aggravates traffic congestion and waste of energy in urban areas. In addition, it offers no quality-of-service guarantee and makes travel time prediction extremely hard. While existing traffic light control research primarily focuses on improving the average wait time of cars, we study in this paper how traffic light scheduling affec...

Objects can differ in brightness and colour. At least that is what our own visual system tells us. It now seems that stomatopod shrimps, and possibly also cephalopod molluscs, can see the direction of the electric vector of light, in much the same way we see colour.
