Light is a potent stimulus for regulating circadian, hormonal, and behavioral systems. In addition, light therapy is effective for certain affective disorders, sleep problems, and circadian rhythm disruption. These biological and behavioral effects of light are influenced by a distinct photoreceptor in the eye, melanopsin-containing intrinsically photosensitive retinal ganglion cells (ipRGCs), ...

This study was conducted to determine the effects of increasing lighting after peak production on eggs production and Hatchable Eggs in broiler breeder Hubbard F15. In this research we used from 4 growing saloons, that in per saloons were 5250 Hubbards broiler breeder hens. In this Experiment we used by Line design way of GLM for analysed data, that we considered the Effects of two parameters, ...

This paper presents the experimental comparison of fourteen stereo matching algorithms in variant illumination conditions. Different adaptations of global and local stereo matching techniques are chosen for evaluation The variant strength and weakness of the chosen correspondence algorithms are explored by employing the methodology of the prediction error strategy. The algorithms are gauged on ...

Artificial lighting systems are used in commercial greenhouses to ensure year-round yields. Current Light Emitting Diode (LED) technologies improved the system efficiency. Nevertheless, having artificial extended for hectares with power densities over 50W/m2 causes energy and demand of be really significant. The present paper introduces an innovative supervisory predictive control strategy opti...

A plant factory with artificial light (PFAL) is defined as an advanced agricultural production system a precisely controlled environment, playing important role in vertical farming and urban food supply. Artificial one of the core technologies PFALs accounts for large part energy consumption; elevating utilization efficiency plants vital sustainable development PFALs. Meanwhile, enclosed struct...

The rapid development of high brightness light emitting diodes (LEDs) has triggered many applications, especially in the area of display lighting. This paper focuses on the application of white LEDs in refrigerated display cases. The fluorescent lighting presently used in commercial refrigerators is inefficient in the application and also it provides poor lighting for merchandising. A laborator...

To judge the quality of a lighting installation is to determine how well it meets context-specific goals in the areas of architecture, economics, and individual wellbeing. The goals for individual well-being are behaviours such as task performance, mood, social behaviour, aesthetic judgements and satisfaction, that occur as a result of internal processes influenced by luminous conditions. These...

Lighting design in computer graphics is essentially not a random process but one driven by both a technical and aesthetic appreciation of lighting. In some applications, the result of the lighting design process is a 2D image derived by rendering a 3D scene. Users with limited understandings of manipulation of lighting parameters may have difficulties in properly modifying the lighting paramete...
