Numerical Treatment of Partial Differential Equations
Author: Christian Grossmann, Hans-Görg Roos, Martin Stynes | Size: 5.20 MB | Format:PDF | Publisher: Springer | Year: November 16, 2007 | pages: 601 | ISBN: 3540715827, ISBN-13: 978-3540715825
This book deals with discretization techniques for partial differential equations of elliptic, parabolic and hyperbolic type. It provides an introduction to the main principles of discretization and gives a presentation of the ideas and analysis of advanced numerical methods in the area. The book is mainly dedicated to finite element methods, but it also discusses difference methods and finite volume techniques.
Coverage offers analytical tools, properties of discretization techniques and hints to algorithmic aspects. It also guides readers to current developments in research with detailed introductions to such recent topics as a posteriori error estimation, discontinuous Galerkin methods or optimal control with partial differential equations. In addition, the authors give basic facts on how to solve generated discrete problems. Chapters on singularly perturbed problems, variational inequalities and optimal control reflect the research interests of the authors.

This Specification provides materials criteria and fabrication requirements for unbonded single-strand tendons used in nonaggressive and aggressive environments. This Specification is not intended to apply to nonstructural elements and applications, which might include topping slabs, waterproofing slabs-on-fill, and post-tensioning used only for control of cracking or deflection. For nonflexural or membrane type structures primarily under tensile forces, the provisions apply where appropriate.

Construction Project Management: A Practical Guide to Field Construction Management, 5 edition
Author: S. Keoki Sears, Glenn A. Sears, Richard H. Clough | Size: 2.4 MB | Format:PDF | Publisher: Wiley | Year: 2008 | pages: 408 | ISBN: 047174588X
For more than thirty years, Construction Project Management by Clough and Sears has been considered the preeminent guide to the Critical Path Method (CPM) of project scheduling. It combines a solid foundation in the principles and fundamentals of CPM with particular emphasis on project planning, demonstrated through an example project.
This Fifth Edition features a range of improvements. New pedagogical devices improve absorption of the material. Updated labor, material, and equipment pricing is incorporated into the text. Coverage is enhanced by discussions of contemporary planning and management methods such as Work Breakdown Structures (WBS) and the Earned Value Management System (EVMS).
A highway bridge with a complete cost estimate, including SI units, illustrates each of the principles of project management. Using this basic information and the case studies in the appendix, readers are given project management problems and hands-on project management experience.
The Fifth Edition features include:
Complete coverage of planning and scheduling principles that apply to every type of construction project
Expanded coverage of production planning
Large foldout illustrations conveniently integrated throughout the book
Thorough and up to date, Construction Project Management, Fifth Edition is a superb text for students and an indispensable on-the-job reference for builders, architects, civil engineers, and other construction professionals.

This textbook on fluid mechanics is aimed at engineering students at Bachelor's degree level. In Chapter 2 the fundamentals of fluid mechanics, needed for the description and analysis of flows in technology, are presented. One-dimensional stream filament theory, along with the momentum integral and angular momentum integral equations, already present us with one method of constructing fluid technological appliances and experiments. For example, the dimensions of a machine can be determined quite accurately in one first step and predictions made about the flow losses which occur.
However, these methods fail when machines are to be optimized, or when appliances are to be developed to operate under extreme conditions, such as silent operation, high efficiency, small dimensions, greatly damped oscillatory behavior, etc. In addition to this, even for most simple cases of application, simple fluid mechanical fundamentals cannot determine the operating behavior of a machine accurately enough. This requires extensive experiments to be carried out and these can be very costly and time consuming.
At this point we refer to more detailed textbooks which progress systematically from the fundamental fluid mechanical equations and their methods of solution to the application of fluid mechanical software.
The methods used in fluid mechanics are analytical, numerical and experimental. Although numerical methods are increasingly used to replace experimental methods, all three are still needed to solve fluid mechanical problems. This book is restricted to theoretical, that is analytical, methods. After working through this book, students are qualified to understand the basics and phenomena of fluid mechanics, and will have obtained an initial insight into fluid mechanical software, even if further studies into the fundamental equations of fluid mechanics and numerical methods are necessary for the application of this software.
The composition of this book is partly very theoretical. In order not to lose sight of the connection to technical applications during the extensive derivations, we have selected flows past airplane wings, flows past vehicles and flows in pipes of process engineering systems as representative examples to illustrate the basics of one-dimensional fluid mechanics.
We now introduce the student to the great variety of fluid mechanical applications, demonstrating that flows are all around us in our technological environment, by describing selected examples of flows in the following introductory sections.
