This paper proposes a novel concept and the related architecture for scalable and flexible lighting control in cities. The goal is to minimize the overall energy consumption without affecting safety. We are proposing a two-level control strategy based on qualitative processing. The lower level Zone Lighting Coordination Unit adjusts the lighting intensity(More)
Decision making in large scale urban environments is critical for many applications involving continuous distribution of resources and utilization of infrastructure, such as ambient lighting control and traffic management. Traditional decision making methods involve extensive human participation, are expensive, and inefficient and unreliable for(More)

The paper presents a control system for an ultrasonic welding device, based on a power inverter, working in commutation, at high frequency, with a frequency control system and an automatic equipment for command. The inverter fed an ultrasonic piezoelectric transducer to activate an ultrasonic welding tool. The frequency control system is based on a feedback(More)
