With the exponential increase of connected products and cheap digital data storage capabilities, applying data analysis and machine learning techniques on commercial datasets has been playing an important role to understand customer behavior. This understanding helps commercial decision-making in various aspects such as suitable time for product promoting or products placement in supermarkets. ...

Increasing user comfort and reducing operation costs have always been primary objectives of lighting control strategies in a building. This paper proposes an architecture of the lighting control system for a daylit office. The system consists of the lighting controller, A/D & D/A converter, dimmable LED lights, and the lighting management software. Verification tests are conducted using the pro...

The inherent control flexibility implied by solid-state lighting – united with the rich details offered by sensor networks – prompts us to rethink lighting control. In this research, we propose several techniques for measuring work surface illuminance and ambient light using a sensor network. The primary goal of this research is to measure work surface illuminance without distraction to the use...

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...
