This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: En este trabajo de investigación se desarrollaron dos controladores modulares con estrategia adaptativa – predictiva, uno para el caso de sistemas con una entrada – una salida (SISO por sus siglas en inglés “Single Input – Single Output”) y otro para el caso de sistemas con múltiples entradas – múltiples salidas (MIMO por sus siglas en inglés “Multiple Input – Multiple Output”). En el presente trabajo se exponen los conceptos básicos de la estrategia CAP para sistemas SISO y sistemas MIMO, haciendo énfasis en la implementación específica que se realizó. Se muestran los resultados obtenidos al implementar las estrategias en distintos procesos con diversas dinámicas de interés para un investigador en el área de control. Estos resultados están basados en distintas pruebas como cambios en referencia, dinámicas variantes en el tiempo, ruido en la señal de control y distintos horizontes de predicción. La finalidad central de este trabajo es de validar el desempeño del esquema de control multivariable propuesto, utilizando sistemas simulados en la plataforma AspenTech HYSYS como nuevo concepto de prueba, la cual permita representar modelos dinámicos de una forma más realista tomando en cuenta las diversas ecuaciones físicas, químicas y matemáticas que rigen su comportamiento.

This book was released on 2008 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: En este trabajo de tesis se implementó un controlador adaptativo predictivo modular y reconfigurable en una plataforma tecnológica de programación. Dichas características permiten aplicar el controlador en diversos sistemas o aplicaciones de control. La motivación de realizar este trabajo de tesis surge de la necesidad de tener sistemas de control que cada vez cumplan mejor los objetivos de control ya que los sistemas convencionales, como el PID, en ocasiones no cumplen con los estándares de calidad requeridos para las aplicaciones industriales. Además, con la teoría de control clásico avanzada y la llegada de la computadora como sistema digital surge la posibilidad de aplicar dicha teoría en sistemas discretos. Una de estas tecnologías relativamente nuevas es el control adaptativo predictivo experto. Dicha estrategia tiene fundamento en la estrategia de control predictivo pero incorpora la adaptación en línea del controlador y el conocimiento experto del sistema en el que se aplique el controlador. En el presente trabajo se exponen los conceptos básicos de esta estrategia de control haciendo énfasis en la implementación específica que se realizó. La implementación realizada se basa en el control adaptativo predictivo, pero se realizó una mejora al introducir el tiempo de retardo como parámetro del controlador. Aunque no se implementó el componente experto como parte del controlador, éste se desarrolló en una plataforma tecnológica que permitirá modificar el controlador en trabajos futuros. Posteriormente se muestra la implementación del controlador y su interfaz gráfica que permite configurar el controlador para diversas aplicaciones. Adicionalmente, se presentan al lector una serie de aplicaciones de control en simulación utilizando el controlador desarrollado mostrando algunas características importantes de su comportamiento ante la variación de los parámetros del controlador. El objetivo de estas pruebas no es mostrar que el control adaptativo predictivo experto es mejor que otras estrategias de control, pues éste tema en particular ya ha sido abordado en otros estudios de tesis, por ejemplo en [14]. Con éstas aplicaciones se valida la implementación modular y la mejora del algoritmo en su manejo del tiempo muerto. Las aplicaciones realizadas consisten en el control de un sistema de primer orden y de un sistema de fase no mínima con la estrategia de control adaptativo predictivo. También se introduce la aplicación del controlador desarrollado en una estrategia de control avanzado conocida como Cascada, permitiendo observar la ventaja de la modularidad del controlador. El trabajo desarrollado es innovador ya que permite la exploración de diversas estrategias de control tal como la estrategia cascada, pues permite la extensión en las aplicaciones al uso de dos o más controladores basados en la estrategia de control adaptativo predictivo.

This book was released on 2009-09-23 with total page 876 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational collective intelligence (CCI) is most often understood as a subfield of artificial intelligence (AI) dealing with soft computing methods that enable group decisions to be made or knowledge to be processed among autonomous units acting in distributed environments. The needs for CCI techniques and tools have grown signi- cantly recently as many information systems work in distributed environments and use distributed resources. Web-based systems, social networks and multi-agent systems very often need these tools for working out consistent knowledge states, resolving conflicts and making decisions. Therefore, CCI is of great importance for today’s and future distributed systems. Methodological, theoretical and practical aspects of computational collective int- ligence, such as group decision making, collective action coordination, and knowledge integration, are considered as the form of intelligence that emerges from the collabo- tion and competition of many individuals (artificial and/or natural). The application of multiple computational intelligence technologies such as fuzzy systems, evolutionary computation, neural systems, consensus theory, etc. , can support human and other collective intelligence and create new forms of CCI in natural and/or artificial s- tems.

Download or read book Artificial Cognitive Architecture with Self Learning and Self Optimization Capabilities written by Gerardo Beruvides and published by Springer. This book was released on 2018-12-14 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces three key issues: (i) development of a gradient-free method to enable multi-objective self-optimization; (ii) development of a reinforcement learning strategy to carry out self-learning and finally, (iii) experimental evaluation and validation in two micromachining processes (i.e., micro-milling and micro-drilling). The computational architecture (modular, network and reconfigurable for real-time monitoring and control) takes into account the analysis of different types of sensors, processing strategies and methodologies for extracting behavior patterns from representative process’ signals. The reconfiguration capability and portability of this architecture are supported by two major levels: the cognitive level (core) and the executive level (direct data exchange with the process). At the same time, the architecture includes different operating modes that interact with the process to be monitored and/or controlled. The cognitive level includes three fundamental modes such as modeling, optimization and learning, which are necessary for decision-making (in the form of control signals) and for the real-time experimental characterization of complex processes. In the specific case of the micromachining processes, a series of models based on linear regression, nonlinear regression and artificial intelligence techniques were obtained. On the other hand, the executive level has a constant interaction with the process to be monitored and/or controlled. This level receives the configuration and parameterization from the cognitive level to perform the desired monitoring and control tasks.

Download or read book Harm Reduction Psychotherapy written by Andrew Tatarsky and published by Jason Aronson. This book was released on 2007-06-10 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This ground-breaking volume provides readers with both an overview of harm reduction therapy and a series of ten case studies, treated by different therapists, that vividly illustrate this treatment approach with a wide variety of clients. Harm reduction is a framework for helping drug and alcohol users who cannot or will not stop completely—the majority of users—reduce the harmful consequences of use. Harm reduction accepts that abstinence may be the best outcome for many but relaxes the emphasis on abstinence as the only acceptable goal and criterion of success. Instead, smaller incremental changes in the direction of reduced harmfulness of drug use are accepted. This book will show how these simple changes in emphasis and expectation have dramatic implications for improving the effectiveness of psychotherapy in many ways. From the Foreword by Alan Marlatt, Ph.D.: “This ground-breaking volume provides readers with both an overview of harm reduction therapy and a series of ten case studies, treated by different therapists, that vividly illustrate this treatment approach with a wide variety of clients. In his introduction, Andrew Tatarsky describes harm reduction as a new paradigm for treating drug and alcohol problems. Some would say that harm reduction embraces a paradigm shift in addiction treatment, as it has moved the field beyond the traditional abstinence-only focus typically associated with the disease model and the ideology of the twelve-step approach. Others may conclude that the move toward harm reduction represents an integration of what Dr. Tatarsky describes as the “basic principles of good clinical practice” into the treatment of addictive behaviors. “Changing addiction behavior is often a complex and complicated process for both client and therapist. What seems to work best is the development of a strong therapeutic alliance, the right fit between the client and treatment provider. The role of the harm reduction therapist is closer to that of a guide, someone who can provide support an

This book was released on 2016-05-31 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological and biomedical research are increasingly driven by experimental techniques that challenge our ability to analyse, process and extract meaningful knowledge from the underlying data. The impressive capabilities of next generation sequencing technologies, together with novel and ever evolving distinct types of omics data technologies, have put an increasingly complex set of challenges for the growing fields of Bioinformatics and Computational Biology. The analysis of the datasets produced and their integration call for new algorithms and approaches from fields such as Databases, Statistics, Data Mining, Machine Learning, Optimization, Computer Science and Artificial Intelligence. Clearly, Biology is more and more a science of information requiring tools from the computational sciences. In the last few years, we have seen the surge of a new generation of interdisciplinary scientists that have a strong background in the biological and computational sciences. In this context, the interaction of researchers from different scientific fields is, more than ever, of foremost importance boosting the research efforts in the field and contributing to the education of a new generation of Bioinformatics scientists. PACBB‘16 hopes to contribute to this effort promoting this fruitful interaction. PACBB'16 technical program included 21 papers spanning many different sub-fields in Bioinformatics and Computational Biology. Therefore, the conference will certainly promote the interaction of scientists from diverse research groups and with a distinct background (computer scientists, mathematicians, biologists). The scientific content will certainly be challenging and will promote the improvement of the work being developed by each of the participants.
