Un libro acerca de los principios y las características de operación del motor de cd, motores de ca y sus aplicaciones en tareas industriales; los controladores lógicos programables en el contexto del modelo Allen-Bradley PLC-5/12; el control PID implementado digitalmente por un PLC; la telemetría de datos con técnicas de modulación por pulsos.

Aunque la bibliografía que cubre los diferentes aspectos de las técnicas de programación y control de proyectos es muy abundante, no existía en la literatura en castellano un manual que recogiera con detalle y de una manera global la amplia gama de tecnicas que surgieron a raiz de la implantacion de los metodos PERT y CPM a comienzos de los años sesenta.El proposito de este libro dice el autor en el prologo es ofrecer una revision, lo mas actualizada posible, de las tecnicas modernas de programacion y control de proyectos.El libro esta dividido en ocho capitulos en los que se estudian: los grafos, los metodos PERT y CPM, el metodo PERT en un contexto aleatorio, el compromiso optimo en la ejecucion de proyectos, la programacion de proyectos a coste minimo, el metodo ROY, la programacion de proyectos con recursos limitados y el PERT-Monte Carlo. En el ultimo capitulo del libro se exponen, de una manera sencilla, los aspectos basicos relacionados con el procesamiento en computador de un programa PERT o ROY. El autor desarrolla su trabajo con una gran claridad de exposicion, apoyando sus explicaciones en continuos ejemplos que facilitan considerablemente la comprension del texto.

El nivel de la presentación es adecuado para los estudiantes que necesitan adquirir los fundamentos de componentes, circuitos y aplicaciones electrónicas. La obra evita las derivaciones extensas para presentar mejor los conceptos básicos, las características de los dispositivos y las aplicaciones en una amplia variedad de campos. En cada uno de los temas se incluyen las ecuaciones, los conceptos y las derivaciones de importancia. Además, esta última edición cuenta con un capítulo sobre magnetismo, y en ella los autores se concentraron en facilitar la lectura del estudiante, evitando abrumarlo con matemáticas innecesarias o con un texto excesivo.

During World War II America s air arms fielded some superlative fighters such as the Republic P 47 Thunderbolt North American P 51 Mustang and Vought F4U Corsair The large numbers of these excellent fighters produced by the US aircraft industry made a significant contribution to the eventual success of the Allies However even as the war was raging and the industry was working flat out to produce the huge numbers of aircraft required for front line duties extensive research and development programmes were also being pursued to create the next generation of fighters This book focuses on the aircraft generated by those programmes and provides a detailed survey of the fighter prototypes produced and flown during the period from 1940 to 1946 which for various reasons did not progress to production and service The work has twenty four chapters that embrace the great diversity of design and layout of these prototypes They demonstrate the remarkable creative flair that was present in the US aircraft industry during the war There are designs of all shapes sizes and configurations powered by piston jet and mixed power plants The designs encompassed various configurations including pusher layouts swept and flying wings Each of these prototypes is given its own
