Sommario/riassunto |

Coeditado por LALICS y CYTED. Este trabajo forma parte de un esfuerzo más amplia de reflexión sobre Ciencia, Tecnología y Sociedad en América Latina, que viene desarrollando el Grupo de trabajo "Ciencia y Sociedad" de CLACSO. En particular, este libro contribuye a alimentar el pensamiento en torno a la generación de políticas de CTI basadas en la evidencia, a partir de la discusión de estudios de caso sobre los procesos de diálogo de las comunidades para construir política pública. Esperamos que la recopilación de estos casos de estudios, estructurados a través del marco analítico que proponemos, sean considerados como un aporte a la construcción de políticas públicas de CTI, basadas en la participación pública, que logren contribuir al desarrollo de ALC y España. |

Sommario/riassunto |
|
This book provides an innovative and mathematically sound treatment of the foundations of analytical mechanics and the relation of classical mechanics to relativity and quantum theory. It treats time as a transformable coordinate, and so moves the teaching of classical mechanics out of the nineteenth century and into the modern relativistic era. It also presents of classical mechanics in a way designed to assist the student's transition to quantum theory. - ;This book provides an innovative and mathematically sound treatment of the foundations of analytical mechanics and the relation of classic |

Sommario/riassunto |
|
This book highlights the applications of optoelectronic chaotic signals in various fields, including lidars/radars, sensors, secure communication, and millimeter/terahertz noise generation. It covers the following topics: - In lidar/radar detection, the book discusses chaotic lidars, chaotic through-wall life detection radars, and chaotic ground penetrating radars. - Regarding optical fiber measurement and sensing, it provides a detailed examination of chaotic time-domain reflection measurement and chaotic distributed fiber sensing technologies. - In the realm of secure communication, the book reviews optical chaos synchronization, chaotic secure optical communication, physical random number generators, and secure key distribution based |

on chaotic synchronization. - For noise generation, it summarizes the millimeter/terahertz noise generation mechanism and noise source prototypes that utilize photo-mixing chaotic lights. This book is a valuable resource for professionals, educators, graduate students, and advanced undergraduates involved in fields such as radar detection, laser technology, fiber optic sensing, optical communication, and testing and measurement technology and instruments. |
