Les chaudi res et les fours industriels sont des quipements essentiels pour de nombreuses industries, notamment celles li es la production d' nergie, de produits chimiques, de m taux et de mat riaux de construction. La technologie des chaudi res et des fours industriels a consid rablement volu au fil des ans pour r pondre aux exigences croissantes de performances, d'efficacit nerg tique et de durabilit environnementale. Les chaudi res modernes utilisent des combustibles fossiles tels que le gaz naturel et le p trole, ainsi que des sources d' nergie renouvelable telles que la biomasse et l' nergie solaire. Les fours industriels utilisent galement une vari t de combustibles et de technologies de contr le des missions pour r duire leur impact environnemental et am liorer l'efficacit nerg tique. Les avanc es dans la technologie des chaudi res et des fours industriels continuent d' tre un domaine cl de recherche et de d veloppement pour r pondre aux besoins futurs de l'industrie.
"Where this book is exceptional is that the reader will not just learn how LTE works but why it works" Adrian Scrase, ETSI Vice-President, International Partnership Projects Following on the success of the first edition, this book is fully updated, covering the latest additions to LTE and the key features of LTE-Advanced. This book builds on the success of its predecessor, offering the same comprehensive system-level understanding built on explanations of the underlying theory, now expanded to include complete coverage of Release 9 and the developing specifications for LTE-Advanced. The book is a collaborative effort of more than 40 key experts representing over 20 companies actively participating in the development of LTE, as well as academia. The book highlights practical implications, illustrates the expected performance, and draws comparisons with the well-known WCDMA/HSPA standards. The authors not only pay special attention to the physical layer, giving an insight into the fundamental concepts of OFDMA-FDMA and MIMO, but also cover the higher protocol layers and system architecture to enable the reader to gain an overall understanding of the system. Key New Features: Comprehensively updated with the latest changes of the LTE Release 8 specifications, including improved coverage of Radio Resource Management RF aspects and performance requirementsProvides detailed coverage of the new LTE Release 9 features, including: eMBMS, dual-layer beamforming, user equipment positioning, home eNodeBs / femtocells and pico cells and self-optimizing networksEvaluates the LTE system performanceIntroduces LTE-Advanced, explaining its context and motivation, as well as the key new features including: carrier aggregation, relaying, high-order MIMO, and Cooperative Multi-Point transmission (CoMP).Includes an accompanying website containing a complete list of acronyms related to LTE and LTE-Advanced, with a brief description of each (http://www.wiley.com/go/sesia_theumts) This book is an invaluable reference for all research and development engineers involved in implementation of LTE or LTE-Advanced, as well as graduate and PhD students in wireless communications. Network operators, service providers and R&D managers will also find this book insightful.
A new approach to CFD that leverages modeling software and is light on mathThis concise, highly illustrated resource gets you started using a new, streamlined method for approaching Computational Fluid Dynamics (CFD) that utilizes commercial software and requires minimal mathematical computations. Developed from curricula taught by the authors, Computational Fluid Dynamics: An Introduction to Modeling and Applications shows how to use high-powered numerical analyses and data structures to analyze and solve problems that involve fluid flows and heat transfer. You will learn how to use the latest computer programs, such as Fluent, to perform the complex calculations required.Coverage includes:Conservation laws in thermal-fluid sciencesThe finite volume methodTwo-dimensional steady state laminar incompressible fluid flowThree-dimensional steady state turbulent incompressible fluid flowConvection heat transfer for two-dimensional steady state incompressible flowThree-dimensional fluid flow and heat transfer modeling in a heat exchangerThree-dimensional fluid flow and heat transfer modeling in a heat sinkSolving the linear and non-linear system of equationsMethods for solving Navier Stokes equationsAnd much more
