In cities, services and are interconnected to provide infrastructure for sustainable growth improvement in quality life citizens. this research work, xplore was new low-cost technologies create intelligent systems capable monitoring controlling luminaires, thus reducing maintenance costs all...

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. ...

The COPE (cost-effective open plan environments) project investigates the effect of open-plan office design on the indoor environment and on the occupant satisfaction with that environment. COPE is sponsored by a consortium of North American public and privatesector organizations and relies on field, laboratory and simulation studies to address design aspects like acoustics, lighting quality, i...

In the context of non-photorealistic imaging, such as digital cel animation, lighting is symbolic and stylized to depict the scene’s mood and the geometric or physical features of the objects in the scene. Stylized light and shade should therefore be intentionally animated rather than rigorously simulated. However, it is difficult to achieve smooth animation of light and shade that are stylized...

This application note describes the LED driving system using a half-bridge LLC resonant converter for high power LED lighting applications, such as outdoor or street lighting. Due to the existence of the non-isolation DC-DC converter to control the LED current and the light intensity, the conventional PWM DC-DC converter has the problem of low-power conversion efficiency. The halfbridge LLC con...
