In this paper is characterized experimentally a closed parking to obtain an empirical propagation model of radio waves at 900 Mhz and identify the conditions and settings required for the assembly and installation of a carbon monoxide, humidity and temperature monitoring system, using IEEE 802.15.4/ ZigBee protocol. From the experimental data, was found that the Path-Loss model evidencing the best...
Scheduling maintenance activities in an electric transmission system has become a constant concern given the need to perform optimal interventions to extend its use while preserving the reliability of the system, without affecting its availability and stability, and at the same time, reducing its costs and environmental impact. This paper has its inception with a planning strategy defined for this...
Digital image processing is a very useful tool because it allows to highlight and extract image attributes that are undetectable by the naked eye. In this work, an algorithm that is able to identify the corners of a rectangular-shaped figure was developed. The figure have to contrast over a darker background than the figure itself. From this information, the processing system obtains the corresponding...
