Book excerpt: "En este documento se presenta un trabajo de Tesis que servirá como requisito parcial para la obtención del grado de Maestro en Ciencias con Especialidad en Sistemas Electrónicos. La siguiente tesis documenta un analisis de propagación de error en un sistema de procesamiento digital implementado con circuitos de Cómputo Aproximado. El Cómputo Aproximado es un paradigma de diseño de Software y Hardware que explota la resiliencia natural a los errores que tienen algunas aplicaciones, remplazando los cálculos exactos de un algoritmo por cálculos aproximados, siempre y cuando éstos últimos sean realizados de forma más rápida y sencilla. El objetivo del cómputo con aproximación inducida en hardware es lograr una mejora en eficiencia energética, tiempo de procesamiento y reducción de complejidad en un circuito a cambio de un leve impacto en la precisión del mismo, lo cual nos ofrece una buena alternativa de diseño para cumplir con restricciones como el consumo energético, el tamaño o la complejidad de un circuito integrado. Sin embargo, uno de los retos principales de diseñar con éste paradigma es determinar que ocurre con el error de cálculo al inducir aproximaciones, ¿el error se incrementa linealmente si aproximarnos todas las rutas de propagación?, ¿existe un fenómeno de compensación?, ¿podemos inferir un comportamiento? En este trabajo se realizó un estudio comparativo de sumadores en paralelo, multiplicador Wallace Tree y el algoritmo de la transformada de Fourier (FFT), comparando resultados entre cálculos exactos y cálculos hechos con hardware aproximado. Los resultados de la investigación demuestran que es posible diseñar circuitos para operaciones aritméticas que presentan un nivel de imprecisión computacional del 1 al 5% con respecto al rango de operación, mientras se alcanzan ahorros de hardware de 10 a 30%. En las conclusiones de éste documento, se presentan al lector los alcances y las limitantes de la estrategia de inducir aproximación por hardware en un sistema computacional."--Resumen hoja [v].

Book Synopsis Banana: Genomics and Transgenic Approaches for Genetic Improvement by : Sukhada Mohandas
Download or read book Banana: Genomics and Transgenic Approaches for Genetic Improvement written by Sukhada Mohandas and published by Springer. This book was released on 2016-09-08 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bananas and plantains are among the most important food and cash crops in the world. They are cultivated in more than 135 countries, across the tropics and subtropics, with an annual global production of ca. 130 million metric tonnes. Though bananas are one of the most important components of food security in many developing countries, banana production is threatened by both abiotic and biotic stresses. These include a wide range of diseases and pests, such as bunchy top virus, burrowing nematodes, black Sigatoka or black leaf streak, Fusarium wilt, etc. In recent years, considerable progress has been made and several biotechnological and genomic tools have been employed to help understand and unravel the mysterious banana genome. Molecular and genomic studies have helped to decipher the Musa genome and its evolution. Genetic linkage map and whole genome sequencing of both Musa acuminata and Musa balbisiana (progenitors of cultivated banana) have completely changed the way of thinking and the approach on banana crop improvement. Whole-genome sequencing has helped to improve the selection of quantitative traits such as yield, as well as the selection of optimal parents for developing required hybrids in breeding programs. Gene isolation and the analysis of mutants have helped in the characterization of genes of agronomic value and the associated regulatory sequences. With the advent of molecular markers and new statistical tools, it is now possible to measure the diversity, identify genes and useful alleles linked to important agronomic traits. Further these alleles can be incorporated into cultivars through marker assisted selection or through transgenic approach. Transgenic approaches are potential tools for direct transfer of these genes into popular cultivars, which are generally not amenable for conventional breeding techniques, in specific with crops such as bananas which are sterile, triploid and heterozygous thereby making it difficult to reconstruct the recurrent genotypes in banana. Transgenic techniques thus have helped overcome the difficulty of working with sterile, triploid banana crop. In the last five years, enormous amount of new information and techniques have been generated for banana. A comprehensive book entitled “Banana: Genomics and Transgenic Approaches for Genetic improvement” on banana genomics, latest transgenic technologies and tools available for improved crop development in banana will address all these requirements.

Book Synopsis National cyber security : framework manual by : Alexander Klimburg
Download or read book National cyber security : framework manual written by Alexander Klimburg and published by . This book was released on 2012 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: "What, exactly, is 'National Cyber Security'? The rise of cyberspace as a field of human endeavour is probably nothing less than one of the most significant developments in world history. Cyberspace already directly impacts every facet of human existence including economic, social, cultural and political developments, and the rate of change is not likely to stop anytime soon. However, the socio-political answers to the questions posed by the rise of cyberspace often significantly lag behind the rate of technological change. One of the fields most challenged by this development is that of 'national security'. The National Cyber Security Framework Manual provides detailed background information and in-depth theoretical frameworks to help the reader understand the various facets of National Cyber Security, according to different levels of public policy formulation. The four levels of government--political, strategic, operational and tactical/technical--each have their own perspectives on National Cyber Security, and each is addressed in individual sections within the Manual. Additionally, the Manual gives examples of relevant institutions in National Cyber Security, from top-level policy coordination bodies down to cyber crisis management structures and similar institutions."--Page 4 of cover.

Book Synopsis Crop Improvement by : Khalid Rehman Hakeem
Download or read book Crop Improvement written by Khalid Rehman Hakeem and published by Springer Science & Business Media. This book was released on 2013-06-13 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The improvement of crop species has been a basic pursuit since cultivation began thousands of years ago. To feed an ever increasing world population will require a great increase in food production. Wheat, corn, rice, potato and few others are expected to lead as the most important crops in the world. Enormous efforts are made all over the world to document as well as use these resources. Everybody knows that the introgression of genes in wheat provided the foundation for the “Green Revolution”. Later also demonstrated the great impact that genetic resources have on production. Several factors are contributing to high plant performance under different environmental conditions, therefore an effective and complementary use of all available technological tools and resources is needed to meet the challenge.

Book Synopsis Development and Growth in the Mexican Economy by : Juan Carlos Moreno-Brid
Download or read book Development and Growth in the Mexican Economy written by Juan Carlos Moreno-Brid and published by Oxford University Press. This book was released on 2009-04-23 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive and systematic English-language treatment of Mexico's economic history to appear in nearly forty years. Drawing on several years of in-depth research, Juan Carlos Moreno-Brid and Jaime Ros, two of the foremost experts on the Mexican economy, examine Mexico's current development policies and problems from a historical perspective. They review long-term trends in the Mexican economy and analyze past episodes of radical shifts in development strategy and in the role of markets and the state. This book provides an overview of Mexico's economic development since Independence that compares the successive periods of stagnation and growth that alternately have characterized Mexico's economic history. It gives special attention to developments since 1940, and it presents a re-evaluation of Mexico's development policies during the State-led industrialization period from 1940 to 1982 as well as during the more recent market reform process. This reevaluation is critical of the dominant trend in economic literature and is revisionist in arguing that, in particular, the market reforms undertaken by successive Mexican governments since 1983 have not addressed the fundamental obstacles to economic growth. Development and Growth in the Mexican Economy also details the country's pioneering role in launching NAFTA, its membership in the OECD, and its radical macroeconomic reforms. Carefully argued and meticulously researched, the book presents a wide-ranging, authoritative study that not only pinpoints problems, but also suggests solutions for removing obstacles to economic stability and pointing the Mexican economy toward the road to recovery.
Book Synopsis Art Gallery Theorems and Algorithms by : Joseph O'Rourke
Download or read book Art Gallery Theorems and Algorithms written by Joseph O'Rourke and published by Oxford University Press, USA. This book was released on 1987 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Art gallery theorems and algorithms are so called because they relate to problems involving the visibility of geometrical shapes and their internal surfaces. This book explores generalizations and specializations in these areas. Among the presentations are recently discovered theorems on orthogonal polygons, polygons with holes, exterior visibility, visibility graphs, and visibility in three dimensions. The author formulates many open problems and offers several conjectures, providing arguments which may be followed by anyone familiar with basic graph theory and algorithms. This work may be applied to robotics and artificial intelligence as well as other fields, and will be especially useful to computer scientists working with computational and combinatorial geometry.
