Book Description
El presente proyecto establece un modelo progresivo de instalación de elementos telecontrolados en una red de distribución en media tensión con el objetivo de mejorar la calidad de suministro eléctrico, siendo la reducción del Tiempo de Interrupción Equivalente de la Potencia Instalada (TIEPI) el criterio principal de mejora. Primeramente se realiza una introducción del sistema eléctrico, redes de distribución en media tensión, su operación de la red y la regulación de los índices de calidad. Seguidamente se presenta una metodología basada en probabilidades para estimar la mejora de la calidad de suministro, según el número de elementos telecontrolados instalados en un circuito, con alimentación única o alternativa del circuito. El cuerpo del trabajo se centra a partir de dicha estimación, mediante el método de localización de averías se halla la forma de cálculo del promedio de maniobras locales a realizar para aislar una avería según el número de tramos del circuito, número de elementos telecontrolados y su disposición. Con tiempos promedios de maniobras locales, tiempo de reparación de la avería y afectación de potencia, se estiman los valores de TIEPI para distintos casos. Estos porcentajes de mejora del TIEPI son comparados respecto a un circuito sin elementos telecontrolados. Finalmente se realiza un análisis económico de viabilidad de inversión con los casos estudiados y se exponen las conclusiones obtenidas.

Book Description
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 Description
This edition of the World Bank has been revised and expanded by the Terminology Unit in the Languages Services Division of the World Bank in collaboration with the English, Spanish, and French Translation Sections. The Glossary is intended to assist the Bank's translators and interpreters, other Bank staff using French and Spanish in their work, and free-lance translator's and interpreters employed by the Bank. For this reason, the Glossary contains not only financial and economic terminology and terms relating to the Bank's procedures and practices, but also terms that frequently occur in Bank documents, and others for which the Bank has a preferred equivalent. Although many of these terms, relating to such fields as agriculture, education, energy, housing, law, technology, and transportation, could be found in other sources, they have been assembled here for ease of reference. A list of acronyms occurring frequently in Bank texts (the terms to which they refer being found in the Glossary) and a list of international, regional, and national organizations will be found at the end of the Glossary.

Book Description
For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.

Book Description
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.

Book Description
Survival data consist of a single event for each population unit, namely, end of life, which is modeled with a life distribution. However, many applications involve repeated-events data, where a unit may accumulate numerous events over time. This applied book provides practitioners with basic nonparametric methods for such data.
