Intelligent supervisory control system for home devices using a cyber physical approach

Although we have many electric devices at home, there are just few systems to evaluate, monitor and control them. Sometimes users go out and leave their electric devices turned on what can cause energy wasting and dangerous situations. Therefore most of the users may want to know the using states of their electrical appliances through their mobile devices in a pervasive way. In this paper, we propose an Intelligent Supervisory Control System to evaluate, monitor and control the use of electric devices in home, from outside. Because of the transferring data to evaluate, monitor and control user's location and state of home (ex. nobody at home) may be opened to attacks leading to dangerous situations. In our model we include a location privacy module and encryption module to provide security to user location and data. Intelligent Supervising Control System gives to the user the ability to manage electricity loads by means of a multi-agent system involving evaluation, monitoring, control and energy resource agents.

Optimal intelligent supervisory control system in cyber-physical intelligence

This paper studies Optimal Intelligent Supervisory Control System (OISCS) model for the design of control systems which can work in the presence of cyber-physical elements with privacy protection. The development of such architecture has the possibility of providing new ways of integrated control into systems where large amounts of fast computation are not easily available, either due to limitations on power, physical size or choice of computing elements.

Supervisory control of a variable speed wind turbine with doubly fed induction generator

This paper is on an onshore variable speed wind turbine with doubly fed induction generator and under supervisory control. The control architecture is equipped with an event-based supervisor for the supervision level and fuzzy proportional integral or discrete adaptive linear quadratic as proposed controllers for the execution level. The supervisory control assesses the operational state of the variable speed wind turbine and sends the state to the execution level. Controllers operation are in the full load region to extract energy at full power from the wind while ensuring safety conditions required to inject the energy into the electric grid. A comparison between the simulations of the proposed controllers with the inclusion of the supervisory control on the variable speed wind turbine benchmark model is presented to assess advantages of these controls.

Juventud vulnerable y escuela media: representaciones y experiencias sobre la autoridad escolar. Vulnerable youth and high school: representation and experiences on scholastic authority.

La investigación busca responder cómo experimentan, se representan y caracterizan grupos juveniles en situación de vulnerabilidad social de la ciudad de Córdoba, la autoridad en la escuela media considerada en tres actores institucionales claves: docentes, preceptores y directores. Se propone indagar acerca de la autoridad desde dos dimensiones: las representaciones juveniles de la autoridad pedagógica (ligada al desempeño de los profesores) y la autoridad en términos de límites que reconocen en los directivos y preceptores vinculándola con el espacio institucional de la escuela. Objetivos Explorar las relaciones con la autoridad escolar vivenciadas en su tránsito por la escuela secundaria por jóvenes en condiciones de vulnerabilidad social de la ciudad de Córdoba. Indagar como vivencian los jóvenes las leyes y normativas escolares atendiendo a la cercanía o distancia con las prácticas que ellos ponen en juego en el seno de sus grupos de referencia. Identificar desde las voces de adolescentes de sectores populares los problemas de convivencia escolar más frecuentes, apuntando a reconocer qué posiciones advierten ante tales situaciones en los adultos que se desempeñan en diferentes roles en la escuela. Explorar en las interacciones y conflictos que se plantean en sus relaciones con docentes, directivos y preceptores. Conocer las valoraciones que los jóvenes efectúan sobre las estrategias de autoridad puestas en juego por profesores (vinculándolas con el desempeño cotidiano en sus asignaturas), preceptores y directivos. Materiales y métodos: Se seguirán dos etapas: a) Realización de grupos focales con adolescentes de 15-17 en situación de vulnerabilidad social que asisten a la escuela media. Se prevé la utilización de muestras intencionales. b) Aplicación de un cuestionario estandarizado a jóvenes de escuelas secundarias en situación de vulnerabilidad. Las preguntas del cuestionario serán elaboradas en forma de escalas de tipo Likert construidas a partir de la información obtenida en la primera etapa Resultados: La investigación producirá conocimientos acerca de: - formas de legitimación de la autoridad escolar por parte de jóvenes socialmente vulnerables - características de la autoridad escolar en docentes, preceptores y directores - modelos institucionales de autoridad escolar Importancia: La significatividad de los resultados se vincula con el marco de las discusiones que se vienen desarrollando en torno a las transformaciones de la educación secundaria, dentro de las cuales la recreación del vínculo docente-alumno y la redefinición de los marcos de autoridad institucionales resultan sustantivos de cara a la mejora. Pertinencia: El trabajo ayudará a identificar núcleos críticos ligados con la gestión de convivencia y de la autoridad escolar, lo que servirá para identificar aspectos de los formatos institucionales que deberían ser revisados y aquellos que podrían ser objeto de afianzamiento y multiplicación.
