Sliding Mode Control of Power Converters
In recent years, a lot of research efforts have been devoted to the application of sliding mode control techniques to power electronic equipment and electrical drives. Hundreds of technical papers have been published in this research field. The tendency stems from the nature of sliding mode with discontinuous control actions and due to its potential for circumventing parameter variation effects along with low implementation complexity. This presentation presents a control design procedures for DC/DC, AC/DC and DC/AC power converters. It summarizes the research results of the power electronics and control systems group at The Ohio State University within the last ten years. It develops novel sliding mode control algorithms with different control objectives, complete and incomplete information about system states. Chattering suppression, power factor, losses and high order harmonics minimization are in the scope of research. A wide range of MATLAB/SIMULINK computer simulations along with experimental results are provided to demonstrate the effectiveness of the proposed control design methodology.

Adaptive Robust Feedback Design: Attractive Ellipsoid Method
This presentation introduces a new technical development of a robust control design for a wide class of nonlinear dynamical systems in continuous time. Control of nonlinear systems are studied in the presence of model uncertainties and bounded external disturbances. The synthesis of feedback with linear structures are discussed. Physical development and implementation of robust high performance controllers for feedback that work in the absence of information on the full model is presented. Some examples (inverted pendulum and a double pendulum of Furuta) to illustrate how to apply the method of ellipsoids Attractive (AEM) for mechanical and electromechanical systems are demonstrated as video-films.

Creando el Caso de Negocio para la Mejora de Procesos en Contextos de Baja Madurez
Antes de comenzar un proyecto de mejora de procesos, con frecuencia se exige desarrollar el caso de negocio para justificar la inversión de tiempo y recursos económicos en las organizaciones. Desarrollar un caso de negocio en ambientes de baja madurez es un reto mayor, ya que debido a su entorno cambiante, estos ambientes son poco aptos para la recolección de datos cuantitativos. Para ello, se desarrolló el Análisis Cuantitativo presentado en esta charla, que tiene el objetivo de evaluar el rendimiento de procesos dinámicos “ad-hoc” en unidades organizacionales pequeñas y de baja madurez. Este análisis requiere de baja inversión y es una solución no intrusiva que ayuda a las organizaciones a reducir las barreras iniciales de la adopción de procesos y demostrar las mayores oportunidades de mejora en términos del negocio. El gran reto de este Análisis Cuantitativo es el de evaluar consistentemente el impacto de los procesos en ambientes en donde no son bien definidos ni repetibles. Para vencer este reto, fue necesario cambiar el paradigma de medición. En vez de medir el rendimiento de cada proceso individualmente, como normalmente se hace en un ambiente de alta madurez, el enfoque del análisis fue el de evaluar el rendimiento integral de la unidad organizacional a través del impacto de las fallas en los procesos. Este Análisis Cuantitativo fue desarrollado en base a múltiples marcos de referencia tales como Goal Question Metric (GQM), Personal Software Process (PSP), y CMMI-DEV. Los resultados proveen información significativa y contundente. Algunos ejemplos de los resultados están: el retrabajo por fase en el ciclo de desarrollo, las mayores causas de retrabajo y su costo para el negocio, las fases más efectivas para prevenir o eliminar los errores, entre otros. Este análisis es una alternativa rápida y no intrusiva que provee una solución para el desarrollo de casos de negocio con costos bajos. Permite crear las rutas de mejora de procesos que ayudan a las organizaciones a alcanzar sus objetivos de negocio. Está basado en conceptos de múltiples marcos de referencia y a la vez mantiene un enfoque ágil para su fácil y rápida adopción en contextos pequeños y de baja madurez.

Advanced nanoporous anodic alumina structures for photonic applications
In the last years structurally engineered nanoporous materials have attracted an increasing interest due to their potential applications in research fields such as electronics, photonic, biotechnology, magnetism, drug delivery, energy, and so on. Nanoporous anodic alumina has become a popular material as a result of their outstanding set of properties and cost-competitive fabrication processes. In this talk, we will present some recent advances in the design and fabrication of photonic micro-nanostructures based on nanoporous anodic alumina. We introduce different electrochemical approaches to modify the pore morphology during or after the fabrication processes (e.g. straight and well-defined pores, cone-like, funnel-like, modulated, hierarchical, three-dimensional, tip-like, etc.) and the design and fabrication of specific structures with enhanced optical response such as tunable porous microcavities, gold-coated nanoporous bilayers, porous distributed Bragg reflectors, nanoporous rugate filters, etc. In a second part, we will show the use of nanoporous anodic alumina as a template and how to create new nanostructures (e.g. nanostructured polymers, nanowires, colloidal fibers). Finally, we will present and discuss some future optoelectronic and optical sensing applications of these nanoporous structures.

Soft Computing Applied to Engineering and Medicine Complex Problems
This presentation introduces the concept of Soft Computing by first defining Artificial Intelligence. After that, the different Soft Computing techniques are introduced, particularly those adopted and studied at the Artificial Intelligence Research Center of the University of Veracruz (CIIA-UV), e.g., evolutionary computing, swarm intelligence, artificial immune systems, among others. The tendency to combine different techniques into one intelligent system is also discussed. After getting some knowledge about Soft Computing and its techniques, a set of applications developed at CIIA-UV are presented. Such applications are classified in two groups: engineering applications and medicine applications. The applications in engineering comprise supply chain optimization, mathematical geometry, mechanical design, scheduling, among others. The applications in medicine cover cervical and breast cancer detection with alternative techniques.
