Drinking water distribution systems - Assessing and reducing risks
Author: Vernon L.Snoeyink, Charles N.Haas, Paul F.Boulos | Size: 6.0 MB | Format:PDF | Publisher: The National Academies Press | Year: 2006 | pages: 404 | ISBN: 0309103061
The distribution system is a critical component of every drinking water utility. Its primary function is to provide the required water quantity and quality at a suitable pressure, and failure to do so is a serious system deficiency. Water quality may degrade during distribution because of the way water is treated or not treated before it is distributed, chemical and biological reactions that take place in the water during distribution, reactions between the water and distribution system materials, and contamination from external sources that occurs because of main breaks, leaks coupled with hydraulic transients, and improperly maintained storage facilities, among other things. Furthermore, special problems are posed by the utility’s need to maintain suitable water quality at the consumers tap, and the quality changes that occur in consumers’ plumbing, which is not owned or controlled by the utility.

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.

thanks in advance.
Hello my friends
I need the article which details of the analysis ( SINGLE PILE AND PILE GROUP IN OVERCONSOLIDATED CLAY (by Y. El-Mossallamy, Arcadis Germany)) exist in the validation PLAXIS 3D FOUNDATION
Landslides represent one of the most destructive natural catastrophes. They can reach extremely long distances and velocities, and are capable of wiping out human communities and settlements. Yet landslides have a creative facet as they contribute to the modification of the landscape. They are the consequence of the gravity pull jointly with the tectonic disturbance of our living planet. Landslides are most often studied within a geotechnical and geomorphological perspective. Engineering calculations are traditionally applied to the stability of terrains. In this book, landslides are viewed as a physical phenomenon. A physical understanding of landslides is a basis for modeling and mitigation and for understanding their flow behavior and dynamics. We still know relatively little about many aspects of landslide physics. It is only recently that the field of landslide dynamics is approaching a more mature stage. This is testified by the release of modelling tools for the simulation of landslides and debris flows. In this book the emphasis is placed on the problems at the frontier of landslide research. Each chapter is self-consistent, with questions and arguments introduced from the beginning.

Hi friends:
I'm searching for this document: "ACI Innovation Task Group 1, Special Hybrid Moment Frames Composed of Discretely Jointed Precast and PostTensioned Concrete Members (ITG-1.2-03) and Commentary (ITG-1.2R-03)". Could anyone help me to get it please??? I'll really appreciate your help.
There were three main impulses which led me to the writing of the present book: My many years of lecturing in special courses for selected students and graduate students-engineers at the College of Civil Engineering of the Technical University in Prague, frequent consultations with technicians and physicists who have asked for advice in overcoming difficulties encountered in solving their problems, and finally many discussions with mathematicians themselves, "pure" as well as "applied". This is also why the book is proposed for a relatively wide range of readers.
