The issue of competence assessment in engineering is analyzed in the context of the lack of motivation for learning. The source of this lack of motivation comes from the distribution of high school students. This assignment creates marginalization for a large number of students. Exit from marginalization can be accomplished through additional motivation. This is the responsibility of the competence...
Light pollution is a phenomenon that needs to be closely monitored. There are currently many SQMs (Sky Quality Meters) that monitor the visibility of stars, but the method has the disadvantage that it does not eliminate the effect of humidity, clouds or aerosols. Another global assessment method uses ISS images that provide detailed information but cannot identify and locate the pollution sources...
Integrating sphere is a device that canhave important structural dimensions and weight, generating the possibility for somedeformations to occur. In general, the measurement chains are used with the analysis of the sources of errors, but no information was found about the errors generated by the integrating sphere itself. Geometric errors caused by imperfections could generate systematic errors, even...
Understanding the lighting distribution is very important even today, when there are available some simulation software. Building a solution for a lighting system, impose to start from an elaborated initial solution, and at every step it is necessary the interpretation of the results. The main hypothesis of the paper consists in the possibility that some errors could be present in these simulations...
Light pollution is a phenomenon that has been reported since a long time, but the specialist's reaction is still modest. There are some attempts for specific regulations. Using photographic tools can be a solution, especially because of the possibilities to achieve global measurements of the lighting field. The purpose of this paper is to substantiate a work in which the general public aware of the...
