Automated tracking offers a number of advantages over both manual and photocell tracking methodologies, including increased reliability, validity, and flexibility of application. Despite the advantages that video offers, our experience has been that video systems cannot track a mouse consistently when its coat color is in low contrast with the background. Furthermore, the local lab lighting can...

this study was conducted to compare the effects of different illumination programs on the cellular and humoral immune system using 320 one day–old male broilers (arian 386) in a completely randomized design of 8 replications (10 birds each). the four assayed lighting schedules were comprised of: 1- continuous lighting (control), 2- decrease then sudden increase of lighting, 3- decreasing-gradua...

This study aims to investigate the effects of lighting color temperatures on elementary students' performance, and thereby propose a dynamic lighting system for a smart learning environment. Three empirical studies were conducted: First, physiological responses were measured as a potential mediator of performance. Second, cognitive and behavioral responses were observed during academic and rece...

Lighting design is an essential element of visual storytelling. In cinematic theory, lighting design plays an important role in illumination, directing viewer’s gaze to important locations, and portraying visual tension. However, lighting design is a complex process, and is especially problematic for interactive entertainment systems, since important design parameters such as spatial configurat...

Chronic stress puts individuals at an increasing risk of numerous health problems. In this study, we present an ambient lighting interface of a biofeedback system that helps users to self-regulate their breathing pattern in a home environment. To evaluate the usability and functionality of the ambient lighting interface, an experiment was conducted with 12 participants. The results suggest that...

Among the non-linear loads used in household, Compact Fluorescent Lamps (CFLs) and LED lamps are becoming more widespread, while incandescent lamps are intended to be replaced by these types of lighting devices. LEDs and CFLs are significantly more efficient and economical than incandescent lamps, and are expected to be used in 100% of residential lighting in the future. As nonlinear loads, LED...

A photosensor is an electronic control device that adjusts the light output of a lighting system based on detected illuminance. While some photosensors simply switch lights on and off, Specifier Reports: Photosensors focuses on photosensors that are used with dimming electronic ballasts to adjust the light output of fluorescent lighting systems over a continuous range. These photosensors are mo...

Crime and feeling of security are pervasive occurrences and can be influenced by lighting conditions. However, lighting improvements are generally concentrated on street lighting. Meanwhile, a vast variety of new technologies, including innovative lighting systems and connected mobility, are entering into the automotive field. Hence, opportunities are not limited only to provide traffic improve...
