Design and Implementation of Takagi-Sugeno Fuzzy Tracking Control for a DC-DC Buck Converter
This paper presents the design and implementation of a Takagi-Sugeno (T-S) fuzzy controller for a DC-DC buck converter using Arduino board. The proposed fuzzy controller is able to pilot the states of the buck converter to track a reference model. The T-S fuzzy model is employed, firstly, to represent exactly the dynamics of the nonlinear buck converter system, and then the considered controller is designed on the basis of a concept called Virtual Desired Variables (VDVs). In this case, a two-stage design procedure is developed: i) determine the reference model according to the desired output voltage, ii) determine the fuzzy controller gains by solving a set of Linear Matrix Inequalities (LMIs). A digital implementation of the proposed T-S fuzzy controller is carried out using the ATmega328P-based Microcontroller of the Arduino Uno board. Simulations and experimental results demonstrate the validity and effectiveness of the proposed control scheme

Mestrado de dupla diplomação com a Université Libre de TunisThis project is a part of my graduation to obtain a computer engineering degree and a
Master degree in Information Systems.
It was realized within IPB and during this period I tried to develop a solution to facilitate
the management of the masters courses in IPB.
The master process is complex and time consuming and thats how was the born of the
iMasters Process idea.
iMasters Process aims to handle the submission, approval and assignment process in the
masters section at IPB. It aims also to help monitoring the development of the work until
the final submission and to handle the jury assignment process for the final defence.
In order to achieve that, i had to understand some new technologies and methodology
that helped me to conceive and to develop an optimized solution.
Based on the literature review, ASP.NET Core and MySQL were chosen for the back-end
development and React Js for the frontend development of the application.Este projeto faz parte da minha graduação para a obtenção do curso de Engenharia da

¿Es adecuado el ABP en el aprendizaje de la fisiología?
The problem-based learning (PBL) as a teaching technique especially useful in medicine applied to clinical science of the profession, gives rise questioning the usefulness of this tool for meaningful learning of medical physiology, biomedical that as a core subject, is leading in the doctor's training, which is why there has been a search for articles and studies which showed the effectiveness of these forms of teaching and learning theories and support us in learning styles of students of medicine and science. This leads us to conclude the usefulness and importance of different techniques in the traditional teaching of physiology.El aprendizaje basado en problemas (ABP) como técnica didáctica útil en medicina en especial aplicada a ciencias clínicas de esta profesión, hace que surja el cuestionamiento de la utilidad de esta herramienta para el aprendizaje significativo de la fisiología médica, que como asignatura básica biomédica, es principal en la formación del médico, por esta razón se ha realizado una búsqueda de artículos y estudios donde se evidencia la efectividad de estas formas de enseñanza aprendizaje, sustentándonos en las teorías y formas de aprendizaje de los estudiantes de medicina y ciencias. Esto lleva a concluir la utilidad e importancia de técnicas diferentes a la tradicional en la enseñanza de fisiología
Sorption Kinetics for Dye Removal From Aqueous Solution Using Natural Clay
The kinetics of the adsorption of Congo red onto natural clay has been studied in an agitation batch adsorber. The Furusawa model has been used to determine the external transfer coefficient for the system and the effect of several experimental variables have been investigated: these include agitation, initial dye concentration, clay mass and clay particle size. The mass transfer coefficient has been correlated with the system variable by the following equation: kf = A(variable)B. Keywords: dyes, adsorption, mass transfer, cla

Regulación emocional y manejo de conflictos conyugales en mujeres de la Iglesia Adventista de la Unión Colombiana del Sur, 2017
El presente estudio tuvo como objetivo determinar la relación entre regulación emocional y el manejo de conflicto conyugales en mujeres de la Unión Colombiana del Sur de la Iglesia Adventista del Séptimo Día, Bogotá, 2017. Corresponde a un estudio correlacional de corte descriptivo no experimental, con una muestra de 520 mujeres casadas. Los instrumentos utilizados para comprobar la hipótesis fueron la dimensión regulación emocional del test de inteligencia emocional TMMS-24 de Extremera y Fernández-Berrocal (2005) y la escala de manejo de conflictos conyugales EEMC de Arnaldo (2001) en su versión de 34 ítems expuesta por Cienfuegos (2011). La regulación emocional posee una correlación positiva y altamente significativa con varias dimensiones de la escala de manejo de conflictos: “Reflexión y Comunicación” (rs = .399, p <.01), “Afecto” (rs = .332, p <.01), “Tiempo” (rs = .376, p <.01), “Automodificación” (rs = .372, p <.01) y “Acomodación” (rs = .276, p <.01). Se aprecia también que la regulación emocional presenta una correlación negativa y significativa con “Evitación” (rs = -.088, p <.05), aunque en un nivel correlacional bajo.TesisLIMAEscuela de Posgrado Unidad de PsicologíaPsicología positiv
Estrategia pedagógica basada en hábitos adecuados del uso del internet que puedan generar procesos de aprendizaje autónomo en estudiantes que cursan primer semestre de Psicología de la UNAD del CEAD Vélez.
Para este proyecto se hace un abordaje del aprendizaje autónomo unido a una estrategia pedagógica de implementación de hábitos adecuados sobre uso del internet, teniendo en cuenta que es la principal herramienta de construcción y evolución de este aprendizaje.
Para esto se realiza una revisión bibliográfica donde se estudia desde la historia de la educación y de la tecnología hasta el punto donde estas se unen para facilitar la educación a nivel mundial y nacional. Abordando desde los primeros autores como Piaget, Ausubel, e investigadores, que plantearon las primeras teorías de la educación, hasta los que en principio hablaron sobre el aprendizaje autónomo y sus primeros estudios.
Se ilustra la unión de la tecnología y medios de comunicación como el internet y demás herramientas de las Tecnologías de la Información y la Comunicación.
También se profundiza sobre la efectividad del aprendizaje autónomo, sus beneficios y dificultades, al igual que su desarrollo y como este influye en el diario vivir.or this project an approach is taken to autonomous learning coupled with a pedagogical strategy of implementation of appropriate habits on internet use, taking into account that it is the main tool of construction and evolution of this learning.
For this, a bibliographic review is carried out, where it is studied from the history of education and technology to the point where they unite to facilitate education at a global and national level. Approaching from the first authors like Piaget, Ausubel, and researchers, that raised the first theories of the education, to those who in principle talked about the autonomous learning and its first studies.
It illustrates the union of technology and media such as the Internet and other tools of Information and Communication Technologies.
It also explores the effectiveness of autonomous learning, its benefits and difficulties, as well as its development and how it influences the daily life.
The chosen approach for this research is descriptive type. Since according to Hernández, Fernández and Baptista (2003) this research approach,
It seeks to specify the properties, characteristics and profiles of individuals, groups, communities or any other phenomenon that is analyzed. To achieve the objective, a focus group was selected, with 14 students from the total population of psychology students from UNAD. The students involved initially responded to a virtual survey, which allowed them to obtain valuable information about their relationship and perception with the internet. Later, three workshops were held that sought to acquire and potentialize skills on the use of the internet and finally to know the degree Of utilization and satisfaction in relation to them, the impact assessment of the same was carried out
