Los trabajadores del Sector de suministro de energía eléctrica tienen el sueldo medio más alto

Según la Encuesta anual de estructura salarial que tiene en cuenta la serie de años desde 2008 a 2016 publicada por el Instituto Nacional de Estadística – INE, la ganancia media anual por trabajador del Sector de suministro de energía eléctrica, gas, vapor y aire acondicionado es la mayor de España con casi 51.000 €. Le siguen el Sector de actividades financieras con algo más de 42.500 € e Información y comunicaciones por un lado e industrias extractivas por el otro con unos 32.400 € de media.

En la Universidad Carlos III de Madrid puedes cursar el Grado en Ingeniería Eléctrica que forma profesionales cuyo perfil coincide con el demandado por las empresas de suministro de energía eléctrica.

Using Google Charts with AppInventor

Google Charts allows to visualize data in websites with a large number of plot types using JavaScript snippets that can be added to the code of the webpage. The code can load any Chart library, add the data to be plotted using the DataTable class, customize the plot and create a usable object with an id that will be used in the webpage with a <div id="id_of_the_chart" style="width: 900px; height: 500px"></div> to display the Google Chart. Easy ready-to-use code can be found in this get started web page.

The following code plots a smoothed function with the array in the variable data.

Abstract—Spatial localization of emitting sources is especially interesting in different fields of application. The focus of an earthquake, the determination of cracks in solid structures, or the position of bones inside a body are some examples of the use of multilateration techniques applied to acoustic and vibratory signals. Radar, GPS and wireless sensors networks location are based on radiofrequency emissions and the techniques are the same as in the case of acoustic emissions. This paper is focused on the determination of the position of sources of partial discharges in electrical insulation for maintenance based on the condition of the electrical equipment. The use of this phenomenon is a mere example of the capabilities of the proposed method but it is very representative because the emission can be electromagnetic in the VHF and UHF ranges or acoustic. This paper presents a method to locate more than one source in space with only two receivers, one of them in a fixed position and the other describing a circumference around the first one. The signals arriving from the different sources to the antennas are first separated using a classification technique based on their spectral components. Then, the individualized time differences of arrival (TDOA) from the sources collected at different angles describe a function, angle versus TDOA, that has all the geometric information needed to locate the source. The paper will show how to derive these functions for any source analytically with the position of the source as unknown parameters. Then, it will be demonstrated that it is possible to fit the curve with experimental measurements of the TDOA to obtain the parameters of the position of each source. Finally, the technique is extended to the localization of the emitter in three dimensions.
