A new study demonstrates that modern electric lighting has caused the near-24-hour biological clock to be set to a later time and that humans physiologically respond to seasonal changes in day length under conditions of natural light exposure.

It is accepted that the visual comfort in schools depends on the quality of the whole visual environment. This leads to the concern upon the quality and quantity of lighting. Currently in Iran, in order to calculate energy transfer for public buildings a coefficient is usually used. This coefficient considers the rate of sunlight energy absorption in these kinds of buildings. To increase the ...

Background: Carpet weaving is an occupation that requires sufficient and appropriate lighting. The lighting in carpet weaving workshops affects the productivity and the physical and mental health of workers. Therefore, the evaluation of the illumination and the identification of work stations requiring lighting modifications will be helpful in promotion of the health and safety of workers in ca...

Most practices applied in the development of lighting usage profile do not reflect the complexity occupants have on lighting loads in residential buildings. This study involves the use of Adaptive Neural Fuzzy Inference System (ANFIS) and regression model for residential load usage profile development, prediction and evaluation for energy and demand side management initiatives. Three variables ...

In allusion to high electricity consumption and resource wasting of college schoolroom, this paper proposes a lighting fuzzy control system based on CC2430. The deviation and transformation rate comparing ideal illumination and the practical one has inferenced by Fuzzy Model Reference adaptive system (FMRAS), and it can compensate natural light illumination stabilizing schoolroom lighting throu...

Marine benthic communities face multiple anthropogenic pressures that compromise the future of some of the most biodiverse and functionally important ecosystems in the world. Yet one of the pressures these ecosystems face, night-time lighting, remains unstudied. Light is an important cue in guiding the settlement of invertebrate larvae, and altering natural regimes of nocturnal illumination cou...

In 2015 and 2016, the RoboCup Standard Platform League’s major rule changes were mostly concerned with the appearance of important game elements, changing them towards a setup that is more similar to normal football games, for instance a black and white ball and white goals. Furthermore, the 2016 Outdoor Competition was held in a glass hall and thus under natural lighting conditions. These chan...
