Download or read book Comunicaciones - una introducción a las redes digitales de transmisión de datos y señales isócronas written by Antonio R. CASTRO LECHTALER and published by Alfaomega Grupo Editor. This book was released on 2013-06-20 with total page 1491 pages. Available in PDF, EPUB and Kindle. Book excerpt: Esta obra está destinada, básicamente, para profesionales y técnicos en informática o ciencias de la computación que deben tener una visión más general, aunque rigurosa, del funcionamiento de las comunicaciones, tan importante para los sistemas computacionales. Los autores han privilegiado una presentación didáctica y amena por sobre otras consideraciones, pues esta obra está orientada especialmente a los alumnos universitarios y también, a los de nivel terciario. Se han evitado algunos desarrollos matemáticos complejos a efectos de facilitar la comprensión de determinados temas fundamentales para aquellos lectores que desean conocer el funcionamiento y las particularidades de los sistemas de comunicaciones, sus antecedentes y la historia de sus orígenes. Los profesionales especialistas en sistemas, informática o computación en muchas oportunidades deben tratar con las empresas de telecomunicaciones servicios o vínculos de las redes que estas operan. En dichas actividades, muchas veces gerenciales, el lenguaje y la estructura física con que las mismas cuentan son de fundamental importancia para saber qué y cómo negociar con ellas. En todos nuestros libros, hemos dado la mayor prioridad a la comprensión didáctica de los distintos temas tratados y a la forma en la que ellos van apareciendo ante la mirada del lector. En particular, debido al uso que, en muchos casos, es posible darle a este texto en cursos donde no cuentan con una currícula con un fuerte contenido físico-matemático, que en muchas carreras resultan innecesarios, hemos optado por reducir el desarrollo de este tipo de contenidos sin que por ello se pierda rigor. El libro incluye temas relevantes del campo de las comunicaciones y, por consiguiente, tendrá la aceptación del público como la que han logrado los autores en obras anteriores sobre estos temas de gran interés actual. Ventaja Competitiva El libro está actualizado a 2012 y cuenta con los datos estadísticos de telecomunicaciones de América Latina, haciendo hincapié en las tecnologías que más se utilizan en nuestros países. Fue evaluado por docentes Mexicanos y se tomaron los cambios que ellos indicaron para que se adapte a las necesidades de su mercado.

Download or read book Comunicaciones digitales: Serie Ingeniería written by Gustavo Villarreal and published by 978-987-1457-08-3. This book was released on 2021-03-26 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Comunicaciones Digitales" sucede a "Principios de Comunicaciones digitales" como libro de texto y manual de referencia y consulta. El cambio de título obedece a una mayor cobertura y profundidad en el alcance de los temas abordados. Son varias las innovaciones que hemos introducido en esta ocasión, contando con el valioso aporte de los profesores Villarreal y Miralles. Entre las más importantes podemos citar wireless donde se aborda el tema con profundidad y claridad conceptual, alcanzando incluso la exposición del sistema de telefonía celular. El desarrollo de los temas se trata en forma amena y respetando la filosofía de enseñanza- aprendizaje, con numerosos cuadros y dibujos preparados para un fácil entendimiento y de acuerdo a modernas técnicas de diseño gráfico. Como el libro de que reemplaza "Comunicaciones Digitales" tiene la intención de propiciar la discusión técnica de los problemas y conceptos teóricos que se ocupan de la transferencia digital de información. Por otra parte, se han actualizado los capítulos de Interfaces de Conexión con la inclusión de puerto USB y un enfoque novedoso de las distintas interfaces para un tratamiento más dinámico del tema, en un todo de acuerdo a las normas en vigencia en la actualidad. Hemos agregado Ethernet con un enfoque actualizado y respetando la premisa de textos claros y profusión de información gráfica. La modificación del capítulo de "MODEM en la transmisión de Datos" está dirigida a la aplicación práctica de los conceptos alcanzados en los capítulos anteriores. Por ese motivo se ha prestado especial interés al desarrollo gráfico del esquema de conexión con técnicas que nos remiten a los esquemas lógicos clásicos de los sistemas telefónicos, con un moderno enfoque que resalta la claridad del concepto a transmitir. Finalmente, creemos que la cualidad principal de este libro en relación con los cursos universitarios y técnicos, no está en el carácter de manual o guía de trabajos prácticos (por lo cual no se han incluido en el mismo ningún ejercicio o problema de resolución o aplicación) sino más bien en la presentación de los de los principios generales en que se asientan las actuales formas de transferencia de información; de manera tal que sirva de base teórica a las experiencias que se realicen en el curso, y como una manera más de realzar la utilidad didáctica de estos prácticos. Los autores hemos tenido la fortuna de estar en contacto con estudiantes y profesores por nuestra actividad académica por un lado, y por otro con ámbitos no académicos de investigación aplicada, desarrollo, montajes y mantenimiento de sistemas en el área de las telecomunicaciones y la informática en el desempeño cotidiano de nuestra profesión. Gran parte de esa experiencia ha sido crudamente expuesta en estas páginas, lo que realza nuestra intención de que esta obra sea una contribución útil para el trabajo de todos.

Book excerpt: Discover how modern technological realities shape freedoms of expression and opinion with this comprehensive resource. The Handbook of Communication Rights, Law, and Ethics delivers an extensive review of the challenges facing modern communication rights. It offers readers an examination of the interplay between communication law and ethics and the role played by communication professionals in protecting individuals’ rights to communication. Distinguished authors Loreto Corredoira, Ignacio Bel Mallén and Rodrigo Cetina Presuel walk readers through the fundamental ideas and concepts that represent universal common ground regarding communication rights. They compare communication rights theories developed in Europe, the United States, Latin America, Australia, and East Asia to describe how communication-related freedoms and rights are formulated and applied around the world. Finally, the meaning of the phrases “freedom of expression” and “freedom of the press” are examined in the context of national constitutions and international human rights instruments.The Handbook of Communication Rights, Law, and Ethics provides readers with: A diverse, global perspective on how communication rights are protected and challenged around the world A universal vision of communication rights that encourages dialogue rather than confrontation A comparison of the American First Amendment of the Constitution with European communication rights theories and other legal traditions around the world An exploration of the frontiers of communication rights concepts, terminology, jurisdiction, and territoriality Perfect for professors, graduate students, doctoral students, and postdoctoral researchers studying communication rights and freedom of expression around the world, The Handbook of Communication Rights, Law, and Ethics also belongs on the bookshelves of researchers studying issues surrounding freedom of the press in North America, Europe, and Latin America.

Available in PDF, EPUB and Kindle. Book excerpt: Benchmarking has become a key tool in the water industry to promote and achieve performance targets for utilities. The use of this tool for performance improvement through systematic search and adaptation of leading practices, has expanded globally during the past decade. Many ongoing projects worldwide aim to address different needs and objectives, in varying contexts, with outstanding results and impact. Benchmarking Water Services provides valuable information to everyone interested in benchmarking in the water industry. The text is aimed at utilities considering joining a benchmarking project, experienced practitioners in charge of organizing a benchmarking exercise, consultants, regulators and researchers. The document is presented with a clear practice oriented approach and can be used as a how-to-benchmark guide presented from different perspectives (participants, organizers, supervising bodies). Readers will gain practical insight on real life benchmarking practices and will benefit from the experiences gained in some of the leading benchmarking projects of the water industry (including the IWA-WSAA benchmarking efforts, the European Benchmarking Co-operation and the several benchmarking projects carried out in Austria and Central Europe). The manual also presents the new IWA Benchmarking Framework, which aims to harmonize the terms used to describe benchmarking and performance indicators practices in the water industry, guaranteeing a more fluent and efficient communication. This Manual of Best Practice is edited by the IWA Specialist Group on Benchmarking and Performance Assessment, and co-published by AWWA and IWA Publishing. Praise for Benchmarking Water Services: "The continual trend of conceptual to specifics throughout the book provides for an educational experience each time the book is either casually perused or carefully studied." "The authors (Cabrera, Haskins and Fritiz) diligently pursue the focus of improvement." "Benchmarking Water Services is an in depth and practical ‘must have’ guide for any utility currently engaged in or planning to develop a benchmarking process" - Gregory M. Baird (2012) Benchmarking: An International Journal 19:2.

Book excerpt: The Covid-19 pandemic caused major disruptions to education around the world. Since the World Health Organization declared a pandemic on March 11, 2020, most students on the planet were affected by the interruption of in-person schooling. To mitigate the educational loss such interruption would cause, education authorities the world over created a variety of alternative mechanisms of education delivery. They did so quickly and with insufficient knowledge about what would work well, for which children, and for what aspects of the schooling experience.Having to create such alternative arrangements in short order was the ultimate adaptive leadership challenge, one for which no playbook existed, one for which solutions would have to be invented, rather than drawn from existing technical knowledge. The nature of the challenge differed across the world and regions, and it differed also within countries as a function of the differential public health and economic impact of the pandemic on communities, and of variations in institutional and financial resources available to redress such impact, including availability of digital infrastructure and previous knowledge and experience of teachers and students with digi-pedagogies and other resources to create alternative education delivery systems.Sustaining educational opportunities amidst these challenges created by the pandemic was an example of adaptive education response not to a unique unexpected challenge but to one in a larger class of problems, just one of the many adaptive conundrums facing communities and societies. Beyond the challenges resulting from the pandemic, other complications of that sort predating the pandemic included those resulting from poverty, inequality, social inclusion, governance, climate change, among others. In some ways, the pandemic served as an accelerant for some of those, augmenting their impact or underscoring the urgency of addressing them. Adaptive puzzles of this sort, including pandemics, are likely to continue to impact education systems in the foreseeable future. This makes it necessary to strengthen the capacity of education systems to respond to them.Reimagining education systems so they are resilient in the face of adaptive challenges is an opportunity to mobilize new talent and institutional resources. Partnerships between school systems and universities can contribute to those reimagined and more resilient systems, they can enhance the institutional capacity of education systems to devise solutions and to implement them. Such partnerships are also an opportunity for universities to be more deliberate in integrating their three core functions of research, teaching and outreach in service of addressing significant social challenges in a context in rapid flux.In this book we present the results of one approach to produce the integration between research, teaching and outreach just described, resulting from engaging graduate students in collaborations with school systems for the purpose of helping identify ways to sustain educational opportunity during the disruption caused by the pandemic. This activity engaged our students in research and analysis, contributing to their education, and it engaged them in service to society. The book examines what happened to educational opportunity during the Covid-19 pandemic in Bangladesh, Belize, the municipality of Santa Ana in Costa Rica, Guatemala, Kenya, in the States of Sinaloa and Quintana Roo in Mexico, South Africa, United Arab Emirates, and in the United States in Richardson Independent School District in Texas. It offers an systematic analysis of policy options to sustain educational opportunity during the pandemic.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the fundamentals of wireless communications and services, explaining in detail what RF spectrum management is, why it is important, which are the authorities regulating the use of spectrum, and how is it managed and enforced at the international, regional and national levels. The book offers insights to the engineering, regulatory, economic, legal, management policy-making aspects involved. Real-world case studies are presented to depict the various approaches in different countries, and valuable lessons are drawn. The topics are addressed by engineers, advocates and economists employed by national and international spectrum regulators. The book is a tool that will allow the international regional and national regulators to better manage the RF spectrum, and will help operators and suppliers of wireless communications to better understand their regulators.
