Abstract

Based on the most recent standards from ASHRAE, the sixth edition provides complete and up-to-date coverage of all aspects of heating, ventilation, and air conditioning. You'll find the latest load calculation procedures, indoor air quality procedures, and issues related to ozone depletion. Also integrated throughout the text are numerous worked examples that clearly show you how to apply the concepts in realistic scenarios. The revision of this text continues to offer comprehensive treatment of heating, ventilation, and air conditioning concepts: All material is based on the updated ASHRAE Handbook and product criteria and uses both SI and English units. Practical, realistic problems are presented and the latest procedures and issues are covered. Suitable for advanced study in HVAC mechanical engineering, architectural engineering, and mechanical engineering technology departments.

Abstract

Structure-Borne Sound" is a thorough introduction to structural vibrations with emphasis on audio frequencies and the associated radiation of sound. The book presents in-depth discussions of fundamental principles and basic problems, in order to enable the reader to understand and solve his own problems. It includes chapters dealing with measurement and generation of vibrations and sound, various types of structural wave motion, structural damping and its effects, impedances and vibration responses of the important types of structures, as well as with attenuation of vibrations, and sound radiation from structures. For the third edition, the author fundamentally revised and newly organized the contents of the work. Nevertheless, the intention has been to preserve the style of the previous editions, namely to focus on the fundamentals enabling the reader to analyse further problems.

Abstract

Gestructureerde matrices zijn zeer belangrijk in lineaire algebra omdat ze minder geheugenplaats innemen dan algemene matrices en omdat bewerkingen met deze matrices minder rekenwerk vergen dan wanneer volle, niet-gestructureerde matrices gebruikt worden. Diagonaal-plus-semiseparabele matrices vormen een klasse van zulke gestructureerde matrices. In dit proefschrift zoeken we naar een geschikte definitie voor deze klasse van matrices en een bijpassende voorstelling.Ook andere definities die in de literatuur gebruikt worden, worden belicht en de studie van diagonaal-plus-semiseparabele matrices wordt gemotiveerd. In een eerste deel construeren we een reductie algoritme dat elke symmetrische matrix omzet in een overeenkomstige diagonaal-plus-semiseparabele matrix. Dit algoritme heeft het Lanczos-Ritz convergentiegedrag en in elke stap wordt er een geneste deelruimte iteratie uitgevoerd. Deel 2 belicht twee basisproblemen uit numerieke lineaire algebra: het oplossen van lineaire systemen en het symmetrisch eigenwaardeprobleem. Eerst construeren we twee snelle algoritmes om diagonaal-plus-semiseparabele lineaire systemen op te lossen. Daarna besprekenwe drie verschillende technieken die gebruikt worden om het symmetrisch eigenwaardeprobleem op te lossen voor diagonaal-plus-semiseparabele matrices: een impliciet QR-algoritme, drie verschillende verdeel-en-heers algoritmes en een Cholesky-LR-algoritme. Het laatste algoritme is enkel toepasbaar op symmetrische, positief definiete diagonaal-plus-semiseparabele matrices. In het laatste deel introduceren we twee hogere rang uitbreidingen van semiseparabele matrices samen met een bijpassende voorstelling. Elke symmetrische matrix kan omgezet worden in een overeenkomstige hogere rang semiseparabele matrix en deze omzetting heeft het blok-Lanczos-Ritz convergentiegedrag gecombineerd met een soort van geneste deelruimte iteratie in elke stap. Numerieke experimenten zijn toegevoegd en de programma's zijn ter beschikking gesteld op het internet. In linear algebra structured matrices are of great interest because they consume less storage than arbitrary matrices and the computational cost of algorithms involving structured matrices is less than for dense, non-structured ones. Several problems can also be translated into similar problems with structured matrices. Diagonal-plus-semiseparable matrices form a class of such structured matrices. First we look for a suitable definition of this class of matrices and a corresponding representation. Other definitions used in the literature are discussed and the study of diagonal-plus-semiseparable matrices is motivated. In Part I of this thesis a reduction algorithm that transforms any symmetric matrix into a similar diagonal-plus-semiseparable one is presented which has a Lanczos-Ritz convergence behavior and performs a kind of nested subspace iteration at each step. It has the advantage that the diagonal can be chosen freely. Part II focuses on two basic problems in numerical linear algebra: the solution of linear systems and the symmetric eigenvalue problem. First, two fast algorithms for solving diagonal-plus-semiseparable linear systems are constructed. Next, three different techniques for solving the symmetric eigenvalue problem of diagonal-plus-semiseparable matrices are presented: an implicit QR-algorithm, three different divide-and-conquer algorithms and a Cholesky-LR-algorithm. The latter is onlyapplicable when the symmetric diagonal-plus-semiseparable matrix is positive definite. In a last part we introduce two higher rank extensions of semiseparable matrices together with a suitable representation. Any symmetric matrix can be transformed into a similar higher-order semiseparable one and this reduction algorithm has a block-Lanczos-Ritz behavior combined with a kind of nested subspace iteration at each step. Numerical experiments are included and the software is made freely available on the internet. Twee fundamentele problemen uit de numerieke lineaire algebra zijn het oplossen van stelsels lineaire vergelijkingen en van eigenwaardeproblemen. Deze problemen zijn vaak een belangrijk onderdeel in toepassingen zoals, bijvoorbeeld bij de zoekrobot Google en in beeldcompressie. Een vaak gebruikte techniek voor het oplossen van bovenvermelde problemen is gebaseerd op tridiagonale matrices. In dit proefschrift wordt een alternatieve manier voorgesteld die gebruik maakt van diagonaal-plus-semiseparabele matrices en die enkele bijkomende voordelen biedt. De eigenschappen van deze diagonaal-plus-semiseparabele matrices zijn in detail bestudeerd. Snelle en stabiele algoritmes voor het oplossen van stelsels lineaire vergelijkingen en eigenwaardeproblemen, specifiek voor deze matrices, zijn voorgesteld.

Abstract

The objective of this book is to collect state-of-the-art research and te- nology for design, analysis, construction and maintenance of textile and in?atable structures. Textile composites and in?atable structures have become increasingly popular for a variety of applications in - among many other ?elds - civil engineering, architecture and aerospace engineering. Typical examples - clude membrane roofs and covers, sails, in?atable buildings and pavilions, airships, in?atable furniture, airspace structures etc. The ability to provide numerical simulations for increasingly complex membrane and in?atable structures is advancing rapidly due to both - markablestrides in computer hardware development and theimproved maturity of computational procedures for nonlinear structural systems. Signi?cant progress has been made in the formulation of?nite elements methods for static and dynamic problems, complex constitutive material behaviour, coupled aero-elastic analysis etc. The book contains 18 invited contributions written by distinguished authors who participated in the International Conference on Textile C- puterandIn?atedStructuresheldinBarcelonafromJune30thtoJuly2nd 2003. The meeting was one of the Thematic Conferences of the European Community on Computational Methods in Applied Sciences (ECCOMAS, www.eccomas.org). The di?erent chapters discuss recent progress and future research dir- tions in new textile composites for applications in membrane and in?atable structures. Approximately half of thebook focusesin describing innovative numerical methods for structural analysis, such as new non linear m- brane and shell ?nite elements. The rest of the chapters present advances in design, construction and maintenance procedures. The content of the di?erent chapters was sent directly by the authors andtheeditorscannotacceptresponsibilityforanyinaccuracies, comments and opinions contained in thetext.
