using by Modeling of Lighting Environment by Kalman Filter Fumiya KAKU , Mitsunori MIKI , Tomoyuki HIROYASU and Masato YOSHIMI (Received October 6, 2010) We propose the fault detection method in Intelligent Lighting System. Modeling of Lighting Environment is used for detection. It shows relation between lighting fixture and illuminance sensor. It is calucated based on log data of Intelligent L...

Rezumat Proiectarea asistată de calculator a sistemelor de iluminat realizează dimensionarea unor instalaţii noi de iluminat cât şi verificarea celor existente, atât pentru sistemele de iluminat interior cât şi pentru sistemele de iluminat exterior. În proiectarea realizată s-a utilizat programul dedicat DiaLux versiunea 4.11. Abstract Computer aided design of lighting systems made new installa...

Over the last decade, a series of experiments sponsored by the U.S. Department of Energy showed that rods play a role in vision in lighting conditions typical of the workplace. The tests took place in realistic environments with typical interior lighting and task conditions. The tests showed that both vision and lighting energy efficiency would be improved if lighting practice accounted for the...

We investigated the synergetic effect between light-emitting diode (LED) lighting efficiency and building energy savings in heating and cooling using an alternative thermal operating system (ATOS) of indoor LED lighting integrated with the ventilation system of a building as an active cooling device. The heat generated from LED lighting and the indoor lighting illuminance were experimentally de...

A number of villages in India is yet to be electrified due to its location. At the same time it is also important to mention that grid connection to those areas is very expensive and time consuming. The source of lighting in those areas are conventional fuel based lighting system i.e. mainly kerosene based lantern. It has immense health hazard and environmental impact. To meet the energy demand...

The aim of this study was to determine the effect of two lighting programs (continuous lighting (CL) 24L:0D and intermittent lighting (IL) 1L:3D) on the broiler performance, carcass traits, incidence of tibial dyschondroplasia (TD), relative asymmetry (RA), duration of induced tonic immobility (TI), heterophils-lymphocytes ratio (H/L), serum glucose, cholesterol and triglyceride levels. The chi...

The comprehensibility of large and complex 3D models can be greatly enhanced by guiding viewer’s attention to important regions. Lighting is crucial to our perception of shape. Careful use of lighting has been widely used in art, scientific illustration, and computer graphics to guide visual attention. In this paper, we explore how the saliency of 3D objects can be used to guide lighting to emp...

Stage lighting is among the most noticeable of the technical theatre disciplines, yet its effects on human attention yet have to be explored using objective measurement. In this paper, we analyze the results of an eye tracking study that determines how various types of stage lighting affect a viewer’s gaze. We found that well lit areas received more attention within lighting setups, but the dif...

objectives : optimum viewing conditions facilitate identification of radiographic details and decrease the need for retakes, patients’ costs and radiation dose. this study sought to evaluate the effects of different viewing conditions on radiographic interpretation. materials and methods: this diagnostic study was performed by evaluating radiograph of a 7mm-thick aluminum block, in which 10 hol...

It has been reliably shown that light is assumed to come from above. There is also some suggestion that light from the left might be preferred. Leftward lighting biases have been observed across various mediums such as paintings, portraits, photographs, and advertisements. As advertisements are used to persuade the public to purchase products, it was of interest to better understand whether lef...
