The traction electric drives for electric rolling stock of alternating current employ the diode and thyristor rectifiers that predetermine a series of shortcomings. These include the significant emission of reactive power and higher harmonics of currents ... see more

In order to minimize the reactive power and higher harmonics of currents, as well as to improve the electromagnetic compatibility of electrical traction networks and systems of railroad automation, modern electric rolling stock of alternating current empl... see more

Automation has been growing in recent years for the manufacturing industries to increase productivity. Multiple robotic arms are used to handle materials for lifting in flexible directions. The vertical rotation of a 360 degree single arm is considered in... see more

Active filter can be used to increase the performance of single-phase controlled rectifier by reducing the generated ripple and harmonic distortion. Active filter can also increase power factor and efficiency of thyristor. In this work, active filter was ... see more

This research work presents a novel architecture of Hybrid Input Energy Harvester (HIEH) system for semi-active Radio Frequency Identification (RFID) tags. The proposed architecture consists of three input sources of energy which are radio frequency signa... see more

This paper describes active suspension with active roll for four-wheel vehicle (bus) by means of an in-series pump actuator with doubled hydropneumatic springs. It also gives full control law with no sky-craping. Lateral stiffness and solid axle geometry ... see more

Programa educativo para el mejoramiento del desempeño profesional pedagógico de los docentes de la ELAM en la atención a la diversidad estudiantil/ The educative program for the improvement of pedagogical professional performance of the Elam academicians Programa educativo para el mejoramiento del desempeño profesional pedagógico de los docentes de la ELAM en la atención a la diversidad estudiantil/ The educative program for the improvement of pedagogical professional performance of the Elam academiciansObjetivo: socializar los resultados obtenidos con la aplicación del programa educativo para el mejoramiento del desempeño profesional pedagógico de los docentes de la ELAM en la atención a la diversidad estudiantil.Materiales y métodos: la metodología utilizada constituye una integración de métodos teóricos, empíricos y matemáticos estadísticos aplicados durante el proceso investigativo. En un momento inicial se realizó el diagnóstico de los estudiantes a partir de los re-sultados obtenidos a los instrumentos aplicados que unido a la sistematización realizada a los referentes permitió diseñar un programa educativo que fue aplicado a la mues-tra seleccionada. En una última etapa se valoró la puesta en práctica de la propuesta.Resultados: en la propuesta se destacan como características: dinámico, participativo, activo y reflexivo, humanista, optimista y responsable, contextualizado y enfoque lúdico. Se encuentra estructurado por cuatro etapas, con cinco formas y alternativas individuales y colectivas de la Educación Avanzada, en cada una de ellas se desarrollan cinco temas relacionados con el desempeño profesional pedagógico de los docentes universitarios en la atención a la diversidad estudiantil.Conclusiones: la propuesta fue valorada, luego de su implementación, como pertinente y necesaria, no solo, para el contexto donde fue aplicada.ABSTRACTObjetivo: to socialize the results obtained with the application of the Educative program for the pedagogical professional performance improvement of Elam academicians in attention to the student diversity.Materials and methods: the methodology used constitutes an integration of theoretical, empirical and mathematical statistic methods applied during the investigation process. At the first moment the students´diagnosis was carried out from the results obtained in the instrument results applied that joining to systematization carried out to the referents al lowed to design an educative program that was applied to the selected sam-ple.In the last period was valorated toput in practice of the proposal.Results: in the proposal are detailed as characteristics: dynamic, participative, active, reflex ive, humanist, optimist, responsible, contextualized with ludical focus. It is structurade for four stages with five forms and individual and collective alternatives of Advanced Education. In each of them are developed five topics related to university cademicians´ pedagogical professional performance in the attention to student diversity.Conclusions: the proposal was assessed, after implementation as pertinent and necessary, not only for the scenary where it was applied.
