Book Description
Inicialmente la información y el conocimiento se depositó en libros, los cuales se almacenaron en las bibliotecas públicas con la finalidad que la ciudadanía pudiera fácilmente acceder a tal cúmulo de conocimientos. Sin embargo hoy en día el volumen de información con el que la humanidad requiere interactuar es muy grande, quedando inadecuadas para tal fin las típicas bibliotecas públicas. Y es aquí donde surge la idea de bibliotecas digitales. Las bibliotecas digitales hacen accesibles a millones de usuarios geográficamente lejanos, extensas cantidades de información de diversos tipos, por lo que es frecuente que los usuarios tengan que esperar abrumadoras cantidades de tiempo para acceder la información que requieren. Esta desventaja de las bibliotecas digitales crece paralelamente con el número de usuarios y la cantidad de información, por lo que es crítico contrarrestarla. Una problemática similar aconteció en el WWW, a la cuál se le dio solución con resultados satisfactorios en el WWW [ABEL98,AVAK99,TASA99,WMEI99,YWOOOO]. Esta solución es la réplica eventual y parcial de la información a la cuál denominaremos caché. La utilización del caché, es transparente al usuario y produce distribución de la carga de trabajo en la red, reduce la concentración de la carga de trabajo del servidor central y a la vez el tráfico de la red al disminuir los accesos remotos a un solo servidor central. El principal aporte de la presente investigación se orienta en el diseño de un Modelo de Servidor Caché para Sistemas Distribuidos, específicamente Bibliotecas Digitales, teniendo como objetivo primordial la minimización del tiempo de acceso a la los documentos de la biblioteca, por medio de la réplica parcial y temporal de documentos solicitados con mayor frecuencia. Así como también una herramienta de simulación del funcionamiento de un servidor caché en una biblioteca digital. Con esta herramienta se implemento y evaluó el modelo propuesto utilizando bitácoras de una biblioteca digital real llamada Phronesis [DGASOO]. El resultado que proporcionó la herramienta fue que el servidor caché resolvió la mayoría de las consultas efectuadas por los usuarios y aligeró la carga del servidor principal a más del 50%. Se encontró también que la política de reemplazo LRU produce mayor desempeño al servidor de caché que FIFO y LFU. También se encontraron tamaños de caché adecuados al patrón de comportamiento de los usuarios de bibliotecas los cuales resultaron ser relativamente pequeños comparados con el espacio total de almacenamiento que la información de la biblioteca requiere para almacenar el total de documentos, búsquedas y resultados.

Book Description
In today's "global village", nearly 450 million people speak English while another 350 million speak Spanish. The United States alone, with its more than 22 million Hispanic Americans, is now considered by many to be a bilingual society. As the practice of law and the resolution of legal issues, to a great extent, is all about precise communication, the impact of this on legal and business professionals is obvious - Spanish/English, English/Spanish translations are fast becoming an indispensable component of any thriving law practice or business, be it a small company or a multinational corporation. Translations are now routinely required for trials, contracts, real estate and financial transactions, and in many other situations. Clearly then, the need for a comprehensive bilingual reference such as this one has never been greater. Wiley's English/Spanish and Spanish/English Legal Dictionary offers comprehensive, up-to-date coverage of more than 40,000 essential words and phrases spanning all legal disciplines and subdisciplines including construction, real estate, insurance, business, trial, environmental law, intellectual property, family law, and more. It was written by a professional translator in collaboration with an advisory committee comprising attorneys from some of the most prominent firms in the international legal community. Featuring an extremely user-friendly format, the Dictionary was designed for quick reference. It directs you instantly to the precise equivalent you need without first "rerouting" you through a maze of other irrelevant terms and phrases. Gender neutral equivalents are provided, and in cases where the nongender neutral term is the norm, both are given.Wiley's English/Spanish and Spanish/English Legal Dictionary puts all important English and Spanish legal terms at the fingertips of attorneys, businesspeople, paralegals, and law students. It belongs on the shelves of law firms, libraries, businesses, and international agencies. It is also an essential communications tool for translators, interpreters, and civil servants.

Book Description
Written by one of the best known object-oriented practitioners in the business, Process Patterns is based on proven, real-world techniques. Scott Ambler shows readers how to successfully deliver large-scale applications using object technology and carefully describes how one develops applications that are truly easy to maintain and to enhance. He shows how such projects can be supported and points out what is necessary to ensure that one's development efforts are of the best quality. His object-oriented software process (OOSP) is geared toward medium to large-size organizations that need to internally develop software to support their main line of business. Developers and project managers who have just taken their first OO development course will find this book essential. It describes the only OOSP to take the true needs of development into consideration, including cross-project, maintenance, operations, and support issues. This book uses the Unified Modeling Language (UML).
