Book Description
Los controles inteligentes son aquellos que tienen la habilidad de actuar apropiadamente en un entorno con incertidumbre, donde una accion apropiada es la que aumenta la probabilidad de consecucion de los objetivos del sistema mediante actividades adaptativas, fusionando asi los metodos matematicos y los metodos cognoscitivos (linguisticos). Los controles inteligentes mas desarrollados en la actualidad estan basados en sistemas expertos tales como: la logica difusa, las redes neuronales y los algoritmos geneticos. Dentro de los sistemas expertos, las redes neuronales han sido ampliamente utilizadas en la identificacion de procesos o como sistemas que optimizan el funcionamiento de un controlador, su principal habilidad es la de aproximar con gran precision funciones no lineales mediante entrenamiento con pares de datos de entrada-salida. Existen diferentes modelos de control neuronal tales como: los controles neuronales indirectos, los controles neuronales directos, los controles adaptativos para sistemas no lineales entre otros"

Book Description
Los graficos de control son herramientas importantes para el mejoramiento de la calidad de la produccion. No obstante su trascendental aplicacion, se reconoce que tienen limitaciones practicas ya que dependen de la apreciacion y juicio humano ademas de considerar a la variable aleatoria con distribucion de probabilidad normal. Cuando la normalidad no se verifica entonces la implementacion y uso de estos graficos de control se hace compleja. En recientes investigaciones, soluciones alternas se han observado mediante el empleo de Redes Neuronales Artificiales. Aunque las investigaciones mencionadas son amplias y demostrativas de esto, se debe reconocer que estos estudios aun se encuentran en fase de experimentacion con datos simulados en el reconocimiento de patrones de variacion de los datos. En este libro se presenta un metodo novedoso de control estadistico de procesos. Este metodo se basa en el reconocimiento de patrones del proceso de manufactura, en los estados de control y fuera de control del proceso. Se propone el uso de la red neuronal FuzzyARTMAP, cuyos parametros han sido determinados a traves de diseno de experimentos."

Book Description
Resumen Últimamente se ha incrementado considerablemente la utilización de la inteligencia artificial en los campos de la electrónica de potencia y de los sistemas de control de la velocidad y del posicionamiento. Estos métodos, basados en sistemas expertos, la lógica difusa y las redes neuronales artificiales, necesitan una gran base de datos o conocimientos que describan el funcionamiento del sistema junto a un análisis lógico, en lugar del análisis matemático, para controlar el sistema y facilitar la toma de decisiones. Uno de estos métodos corresponde a las redes neuronales artificiales. En esta tesis doctoral se presenta la aplicación de redes neuronales artificiales en los sistemas de control vectorial y control directo del par para una máquina de inducción. Esta tecnología, relativamente nueva, sirve para poder reemplazar eficientemente algunos equipos analógicos ya existentes. Los datos necesarios para entrenar las redes neuronales artificiales se obtienen, en primer lugar, de los resultados de las simulaciones del sistema formado por el motor y su control, y en segundo lugar, a partir de los resultados experimentales. A tal fin se implementa un modelo del motor de inducción que se prueba con motores de diferentes valores nominales y se controla con diferentes sistema de control: control vectorial por el método indirecto con y sin realimentación de velocidad, control vectorial por el método directo con realimentación de velocidad y control directo del par. Para el caso de los sistemas del control vectorial por el método indirecto, con y sin realimentación de velocidad se han utilizado redes neuronales artificiales de respuesta a impulso finito (FIRANN) para emular algunos bloques de los sistemas del control vectorial tales como la estimación de referencia de corriente estator. Cada red neuronal artificial se ha diseñado, entrenado y probado como una parte del conjunto del sistema de control. Con respecto al control vectorial por el método directo y con reali.

Book Description
Theory of Particulate Processes: Analysis and Techniques of Continuous Crystallization, Second Edition covers the numerous population balance-based particulate studies. This edition emerged from the notes for an industrial short course on crystallization. This book is divided into 10 chapters and begins with an outline of the methods for representation of particle distributions and a systematic approach to the predictive modeling of processes where there is a need to characterize distributions in time and space and by some identifying property. The succeeding chapters provide a specific and more elementary approach to modeling crystal size distributions, as well as the modeling the kinetics of crystal nucleation and growth rates. Other chapters discuss a wide range of system analysis and design considerations specific to crystallization for both the steady state and unsteady state. The final chapters illustrate the use of a population balance analysis to interpret data from both laboratory and process equipment. These chapters also explore a wide variety of particulate processes and systems for which the population balance analysis is useful. This book is of great value to graduate students with particulate systems course.

Book Description
Computer vision has become increasingly important and effective in recent years due to its wide-ranging applications in areas as diverse as smart surveillance and monitoring, health and medicine, sports and recreation, robotics, drones, and self-driving cars. Visual recognition tasks, such as image classification, localization, and detection, are the core building blocks of many of these applications, and recent developments in Convolutional Neural Networks (CNNs) have led to outstanding performance in these state-of-the-art visual recognition tasks and systems. As a result, CNNs now form the crux of deep learning algorithms in computer vision. This self-contained guide will benefit those who seek to both understand the theory behind CNNs and to gain hands-on experience on the application of CNNs in computer vision. It provides a comprehensive introduction to CNNs starting with the essential concepts behind neural networks: training, regularization, and optimization of CNNs. The book also discusses a wide range of loss functions, network layers, and popular CNN architectures, reviews the different techniques for the evaluation of CNNs, and presents some popular CNN tools and libraries that are commonly used in computer vision. Further, this text describes and discusses case studies that are related to the application of CNN in computer vision, including image classification, object detection, semantic segmentation, scene understanding, and image generation. This book is ideal for undergraduate and graduate students, as no prior background knowledge in the field is required to follow the material, as well as new researchers, developers, engineers, and practitioners who are interested in gaining a quick understanding of CNN models.
