This book systematically summarizes the accuracy, precision, and repeatability levels of field-based tests applied in soccer. It considers such details as the effectiveness of tests for different age categories and sexes. In this book, the readers will be able to check all the field-based tests conceived for fitness assessment in soccer through a large systematic review made to the literature. In addition a brief characterization of each test and presentation of the concurrent validity and repeatability levels for each test will be provided. Finally, the book contains a general discussion of the implications of the tests for different methodological approaches to training. It will be use to sports scientists and practitioners.

This work relates to the application of Artificial Intelligence to tool wear monitoring. The main objective is to develop an intelligent condition monitoring system able to detect when a cutting tool is worn out. It is used a combined Expert System and Neural Network able to process data coming from external sensors and combine this with information from the knowledge base and thereafter estimate the wear state of the tool. The novelty of this work is mainly associated with the configuration of the proposed system. With the combination of sensor-based information and inference rules, the result is an on-line system that can learn from experience and can update the knowledge base pertaining to information associated with different cutting conditions. Two neural networks resolve the problem of interpreting the complex sensor inputs while the Expert System, keeping track of previous success, estimates which of the two neural networks is more reliable. In this study an on-line tool wear monitoring system for turning processes has been developed which can reliably estimate the tool wear under common workshop conditions.

El presente trabajo tiene como proposito la generacion de una propuesta formativa complementaria, en el area de Agroecologia, apoyada en tecnologia de informacion con la plataforma Chamilo y basada en modelos de entornos de aprendizaje constructivistas. Se realiza sobre la base de la experiencia de los autores como formadores del Programa Todas las Manos a la Siembra (PTMS), el cual es un programa estrategico nacional generado en Venezuela para avanzar en la transformacion del modelo de agroproduccion agrotoxica hacia el modelo agroecologico. La propuesta formativa surge del diagnostico obtenido de las necesidades de formacion teorico/practicas de los docentes de educacion basica y se presenta como una alternativa que complementa la formacion presencial, para la adquisicion de destrezas en la planificacion de los proyectos socioproductivos en el aula. Por lo que se constituye en un aporte significativo para la facilitacion en agroecologia a nivel nacional."
