This paper presents the dynamic optimization of a pseudo-azimuthal tracking system for photovoltaic modules regarding the growth of energetic efficiency. The study targets on the one hand the optimization of the mechanical device of the tracking mechanism (developed with the MBS software solution ADAMS), and on the other hand the optimization of the control system model (conceived with the DFC software EASY5). The main aspect consists of using the

As the number of objects in Earth’s atmosphere and in low Earth orbit is continuously increasing; accurate surveillance of these objects has become important. This paper presents a generic, low cost sky surveillance system based on stereovision. Two cameras are placed 37 km apart and synchronized by a GPS-controlled external signal. The intrinsic camera parameters are calibrated before setup in the observation position, the translation vectors

The declining functionality associated with membranes ageing includes changes in physical parameters, such as, thickness, roughness and density of defects, but also in chemical structure. All these factors impact synergistically on the major performance indicators: permeability and salt rejection. In this study, three types of commercially available RO membranes were statically exposed to hypochlorite solutions and analysed by Fourier transform infrared
