Juan Alberto Cabrera is a EcoLogic Computing // Postdoctoral researcher at TU Dresden at EcoLogic Computing. He possess expertise in matlab, c++, electronics, programming, signal processing and 26 more skills. He is proficient in Danish and English. Colleagues describe him as "This is to certify that Mr. Juan Alberto Cabrera Guerrero, student of “UNIVERSIDAD SIMÓN BOLÍVAR”, stayed from January 15th to June 29th, 2012, at Czech Technical University in Prague (CTU), Faculty of Electrical Engineering as an intern in Aerospace systems laboratory. Mr. Cabrera worked on the project titled “Evaluation of Analogue and Digital Sun Sensor Parameters”. During the time he spent with us he assembled about five prototypes of an analogue sun-sensor which is based on mechanical arrangement of two solar cells differentially connected and lighted by a sunbeam crossing a mechanical slit. The mechanical composition was especially difficult because the student used solar cells which were difficult to connect with the rest of the system. Mr. Cabrera destroyed a lot of solar cells but at the end he invented a method how to repeatedly assemble the sun-sensor elements. He designed a mechanical shutter which was used to measure performance of the sun sensors with different shutter setting. The student was able to learn and use remotely controlled laboratory instruments with which he designed an Automated Test Setup that was used to measure characteristics of the proposed sensors. Finally, Juan measured multiple sets of characteristics of three sensor elements with proposed improved linearity of the transfer characteristics. These measurements differed in slit width, slit distance from the sensor element and shape of the solar cell correction cover in comparison with commonly used triangle shape. All of the measurements were acquired from Matlab environment and all the sensor characterization was performed by MS Excell. While dealing with this comprehensive task, Juan was also preparing his master thesis that summarizes his accomplishments. Juan has very good knowledge about electronics, programming, Matlab and data processing. He was not able to finish his master thesis here in the Czech Republic due to time constraints. I honestly admire the fact, he finished his thesis outside of our university, at home in Venezuela, where he successfully defended his thesis and then translated the thesis into English. Juan expressed an active attitude for problem solving, he is communicative, right in dealing and reliable."
