Computational Modelling and Advanced Simulations

Book Name:Computational Modelling and Advanced Simulations (Computational Methods in Applied Sciences) free ebook download
Author:Justin Murin, Vladimir Kompis, Vladimir Kutis|Publisher:Springer
ISBN: 9400703163 | 364 pages | PDF | 10.13 MB

Product Description: This book contains selected, extended papers presented at the thematic ECCOMAS conference on Computational Modelling and Advanced Simulations (CMAS2009) held in Bratislava, Slovakia, June 30 – July 3, 2009. Modelling and simulation of engineering problems play a very important role in the classic and new composite material sciences, and in design and computational prototyping of modern and advanced technologic parts and systems. According to this, the existing numerical methods have been improved and new numerical methods have been established for modelling and simulation of more and more complex and complicated engineering problems. The present book should contribute to the effort to make modelling and simulation more effective and accurate.

System Modelling and Simulation

Book Name:System Modelling and Simulation free ebook download
Author:V.P. Singh|Publisher:New Age Publications
ISBN: 8122423868 | 247 pages | PDF | 13.2 MB

Although a number of books and research papers have appeared in the literature, a need is felt to have a systematic study of the subject which inculcates into designing and preparation of this book, updated with engineering applications. The basic techniques of Modeling and Simulation are now being taught in undergraduate engineering courses and its applications in various engineering subjects require detailed studies. An attempt has been made to make this treatise useful to engineers as well as scientists, especially defence scientists. Most of the chapters in the book are based on the papers published by the author in various technical journals. Various mathematical and computer models were incorporated to have an efficient understanding of the basics system development. In order to make the analysis easier to understand, basic mathematical techniques such as probability, discrete & continuous system, queuing system which will be essential for the understanding of the subject have also been discussed. Rather than these mathematical topics, other topics dealing with aircraft and warheads, in which various components such as survivability analysis, vulnerability and cost effectiveness are included. System dynamics and inventory control model give the basic perspective of growth and delivery rate system.

Modeling: Specification and Implementation

Book Name:Information Modeling: Specification and Implementation free ebook download
Author:David Edmond|Publisher:Prentice Hall
ISBN: 0134577485 | 606 pages | PDF | 4.27 MB

This book provides basic concepts and framework of information modeling. It is also an introduction to the specification and implementation of organizational information systems. It aims to combine and integrate these traditionally compartmentalized activities. This unity is achieved through the use of a relational specification language Z in conjunction with the relational database language SQL. Both these languages have their roots in predicate logic and set theory. Features of the book include: - An introduction to sets, functions and relations which provide the essential foundations for understanding information systems. - A thorough coverage of SQL. - An introduction to database design through two contrasting graphical notations -- conceptual schema and entity-relationship diagrams. - An introduction to the essential components of the Z notation and to the conventions regarding its use. - A discussion of the relationship that must be established between an information system as implemented and its original specification. - Case studies. - End-of-chapter exercises, many of which are answered thus allowing students to pace themselves through the book. The book suggests that we should take a knowledge-based approach to the development of information systems, with the knowledge first being represented using Z and then re-stated as application programs that use SQL to process a database. Thus the book will be of interest to computing professionals who work in the areas of systems analysis, database design and application programming. It will also provide an integrated introduction to these topics for students of information systems and computer science.

Groundwater Pollution: Theory, Methodology, Modelling, and Practical Rules

Book Name:Groundwater Pollution: Theory, Methodology, Modelling, and Practical Rules (Developments in Water Science) free ebook download
Author:Jean J. Fried|Publisher:Elsevier Science Ltd
ISBN: 0444413162 | 347 pages | PDF | 12.01 MB

Pollution has become the ever-increasing monster that threatens our civilization (what is left of it, at least), the Moloch that will eat us. This is what the information media say, and perhaps they are right; now again perhaps they are wrong, or at least too pessimistic. We feel that the real danger is not pollution but the ignorance of pollution problems. This book built around the example of groundwater pollution, is an attempt to rationalize and to quantify the problem and to show that the danger of pollution should not be despised, of course, but conversely, it should not be exaggerated.

Neural Networks and Sea Time Series: Reconstruction and Extreme-Event Analysis

Book Name:Neural Networks and Sea Time Series: Reconstruction and Extreme-Event Analysis free ebook download
Author:Brunello Tirozzi, Silvia Puca, Stefano Pittalis, Antonello Bruschi, Sara Morucci|Publisher:Birkhauser Boston
ISBN: 0817643478 | 180 pages | PDF | 11.31 MB

Increasingly, neural networks are used and implemented in a wide range of fields and have become useful tools in probabilistic analysis and prediction theory. This book—unique in the literature—studies the application of neural networks to the analysis of time series of sea data, namely significant wave heights and sea levels. The particular problem examined as a starting point is the reconstruction of missing data, a general problem that appears in many cases of data analysis. Specific topics covered include: * Presentation of general information on the phenomenology of waves and tides, as well as related technical details of various measuring processes used in the study * Description of the model of wind waves (WAM) used to determine the spectral function of waves and predict the behavior of SWH (significant wave heights); a comparison is made of the reconstruction of SWH time series obtained by means of neural network algorithms versus SWH computed by WAM * Principles of artificial neural networks, approximation theory, and extreme-value theory necessary to understand the main applications of the book. * Application of artificial neural networks (ANN) to reconstruct SWH and sea levels (SL) * Comparison of the ANN approach and the approximation operator approach, displaying the advantages of ANN * Examination of extreme-event analysis applied to the time series of sea data in specific locations * Generalizations of ANN to treat analogous problems for other types of phenomena and data This book, a careful blend of theory and applications, is an excellent introduction to the use of ANN, which may encourage readers to try analogous approaches in other important application areas. Researchers, practitioners, and advanced graduate students in neural networks, hydraulic and marine engineering, prediction theory, and data analysis will benefit from the results and novel ideas presented in this useful resource.
