Book Description
El objetivo principal de esta tesis está dirigido al diseño de una estrategia de control adaptativo-predictivo basada en redes neuronales para el control de sistemas no lineales. Con el objeto de realizar el control se emplea una red neuronal que ejerce de modelo de la planta y otra red que ejerce las labores de controlador. El ajuste de los parámetros de la primera se realiza fuera de línea, quedando fuera del marco de esta tesis su adaptación en línea y asumiendo que con la información adecuada se puede disponer de un correcto modelo. La red neuronal que ejerce de controlador en cambio se adapta en línea en base al funcionamiento que el lazo presenta. Para poder realizar esta adaptación se realiza una modificación del algoritmo de entrenamiento dentro de la estrategia adaptativo-predictiva presentada. Esta modificación hace uso de la información que proporciona la red neuronal identificadora, que además de la predicción del comportamiento del sistema proporciona las derivadas parciales de entrada/salida necesarias en el entrenamiento del controlador. Dentro de la estrategia y del algoritmo de entrenamiento se ha trabajado en la formalización de los aspectos de la estabilidad del lazo de control. Esta estrategia ha sido probada en varios casos de uso y presentada en diversos foros tanto nacionales como internacionales.

Book Description
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.

Book Description
The intersection of insurance regulation and trade agreements is of obvious significance to international competitiveness and, thereby, to national welfare. Yet until this masterful study the subject has remained virtually unexplored. Insurance Regulation in North America, far from merely addressing this important area of theory and practice, superbly balances a world of detailed analysis and commentary with deeply insightful interpretation and debate. The book's focus on insurance regulation in three countries allows the authors to approach the subject in an extraordinary depth that could not be achieved in a more global account. In the course of their treatment the authors offer the reader the following invaluable insights, among many others:analysis of the political dimension of reaching agreements and of implementing them;comparison of the three major trade agreements that apply in the North American insurance market'NAFTA, WTO agreements on financial services, and MEUFTA (the Mexico-European Union Free Trade Agreement)'with emphasis on the relationship between GATS and NAFTA principles;investigation of the clear convergence of regulatory schemes and the probable limits to harmonization;discussion of the arbitrage by which companies get around regulatory restrictions and exploit opportunities created by loopholes;clarification of the crucial issues surrounding the role of customary international law principles in investor protection obligations;discussion of the level of government and which government agencies a company must turn to in order to satisfy legal requirements;analysis of the jurisprudence of the Supreme Court of Mexico regarding legal effects of treaties on domestic law;commentary on the effects of demutualization and of mergers and acquisitions;discussion of the effect of the entrenchment of U.S. State regulations and the federal government's lack of clear power to force State compliance; anddescription of dispute settlement procedures between governments. Although important issues arising in each of the three countries are all covered, there is an emphasis on the Mexican market in recognition of Mexico's greater future growth potential and of the relative paucity of relevant literature in English. Major case studies that reveal processes of compliance or conflict are analyzed in detail. For insurance professionals'lawyers, business executives, and policymakers'who want to understand what international trade agreements contain, how they work, and how they affect domestic insurance regulation and business strategy in what is rapidly becoming a global market for insurance and other financial services, this book is a gold mine. Scholars and academics in insurance law and international economic law will also find here a fresh new treatise of great significance.
