Evaluation the torque generated by the actuator systems is a problem in that the forces obtained have small values. The experimental stands used to evaluate the performance of an actuator must allow an easy adjustment of the measuring equipment to the characteristics of the tested system. The paper presents the mathematical model of a quadrilateral mechanism used in a stand designed to measure the...
In this paper we give a stipulative definition of the term “situation” (a reductionist representation of the world seen as being psychological (ψ) and physical (φ) drivable) and we apply it for defining the concepts of visiting-situations tracking system (VSTS) and visiting-situations aware system (VSAS). We use these concepts to treat the hypothetical case of a HERMES service (Heritage Enriching...
Because of the increasing awareness that the energy market can help to prevent or combat global heating, it's crucial to curb the energy consumption controlled. This paper discusses the development - step by step - of a home management system in order to decrease the energy intensity of a dwelling. The application is based on the model of a house with renewable sources: PV-panels, a solar collector...
Electronical power and control systems can decisively influence the performance of the piezoelectric engines and actuators. This paper presents the modeling of some ultrasonic motor and the role of some equipments that amplifies signals of variable frequency with the lower limit of 20 kHz and various wave forms, in order to obtain new performance in using the types of engines achieved in the Research...
