A Posterori Error Estimation in Finite Element Analysis

[Image: info.png]
Mark Ainsworth, J. Tinsley Oden, "A Posterori Error Estimation in Finite Element Analysis"
Wiley-Interscience | 2000-01-15 | ISBN: 047129411X | 240 pages | PDF | 5,4 MB

[Image: screen.png]
[Image: 89254019556057412157.jpg]

An up-to-date, one-stop reference–complete with applications

This volume presents the most up-to-date information available on a posteriori error estimation for finite element approximation in mechanics and mathematics. It emphasizes methods for elliptic boundary value problems and includes applications to incompressible flow and nonlinear problems.

Recent years have seen an explosion in the study of a posteriori error estimators due to their remarkable influence on improving both accuracy and reliability in scientific computing. In an effort to provide an accessible source, the authors have sought to present key ideas and common principles on a sound mathematical footing.

Topics covered in this timely reference include:

# Implicit and explicit a posteriori error estimators
# Recovery-based error estimators
# Estimators, indicators, and hierarchic bases
# The equilibrated residual method
# Methodology for the comparison of estimators
# Estimation of errors in quantities of interest

A Posteriori Error Estimation in Finite Element Analysis is a lucid and convenient resource for researchers in almost any field of finite element methods, and for applied mathematicians and engineers who have an interest in error estimation and/or finite elements.

Windows is famous for getting more sluggish the more you use it. One reason for this is that many programs leave your computer full of digital garbage when you remove them. Every time you try out a new program and then uninstall it your system gets more and more clogged up with redundant program components that just get in the way and slow things down.

Contents of the UnInstaller toolbox:

* Automatic and manual monitoring of program installation
* Monitor secret program activities
* Remove all traces of programs from your system
* Interactive tool for removing programs for which you don’t have
Ashampoo UnInstaller installation logs
* Reinstaller – reinstall programs with all your settings

Applied Hydrogeology (Fourth Edition)

by C W Fetter
Publisher: Prentice Hall Inc, USA.
Page: 598

Hydrogeology is now considered to be a core course in the curriculum of undergraduated geology programs of civil engineering as well as many fields of engineering. There is ongoing demand for persons with training in hydrogeology by consulting organisations and state.

Most of the employment in hydrogeology is in the environmental area. This is a book that will help prepare students for either a career in hydrogeology or in other areas of environmental science and engineering where a strong background in hydrogeology is needed.

Applied Hydrogeology is intended as a textbook for an introductory course in hydrogeology taught either at the advanced undergraduated level or as a dual level undergraduate/graduate course. It is also useful in helping individuals who are preparing to take state examinations for professional registration as a hydrologist or hydrogeologist. It can be found as a reference book in the personal library of many working professionals.

  Discussion about the base isolation design
Posted by: tibas - 06-10-2010, 07:48 PM - Forum: Calculation Notes & Analysis Files - Replies (2)

Dear all,
I want to open a new thread to discuss the calcul and designing of the buildings with seismic isolation devices.
We all know the procedure to start this study:

1/ Predimensioning the device (isolator devices);
2/ input the numerical model;
3/ Analysis of Results and verification

Discuss for threes last procedure
How predimensioning the device?
How input the numerical model?
What code or condition to Analysis of Results and verification?




Let us discuss it.

Best Regards.

Applied Hydrology
by Ven Te Chow, David R Maidment, Larry W Mays
Publishers: McGraw Hill Book Company Inc., USA
Size: 104 MB (PDF)

Applied Hydrology (Civil Engineering) Book Info:

This book is designed for a hydrologist, civil, or agricultural engineer. The text presents an integrated approach to hydrology, using the hydrologic/system or control volume as a mechanism for analyzing hydrologic problems.

This book is a useful book for teaching in the graduate class for civil engineers who are targeting a graduate degree with emphasis on hydrology. It might be a little advanced for undergraduates, but certainly is in the grasp of advanced undergraduate students.

Applied Hydrology is the text, which Chow was still alive but had not finished the book. Applied Hydrology was assembled posthumously by Maidment and Mays, who did a good job putting together whatever remained of Chow's work. It's an important text for water and hydrology relevant discipline specialty.

Part 1 of the text covers the basics and does it well. This material is timeless and will not change much as new research comes available. Part 2 covers analysis and shows its age, just a bi t. Unit hydrographs and lumped-flow routing are old technologies and while updates are inevitable, the basic technologies will not change. Chapters 9 and 10 are a bi t dated as substantial work has been done over the last 15 years. They're still good, but require supplementation. Chapters 11 and 12 again contain great fundamentals but the technology is changing. The theory of linear moments (L-moments) is working its way into hydrologic statistics for fitting distributions to datasets. Furthermore, there is a trend toward using resistant statistics (median, inter-quartile range, and others) for description of the statistics of hydrologic datasets. Part 3 on hydrologic design is still good, but is also showing its age just a little. Again, the basics are great and well-explained. However, as new data become available and new analyses of those data are accomplished, new interpretations also become available. This is true especially with precipitation atlases and the estimation of n-year precipitation events, and hence n-year hydrologic events.

Applied Hydrology is the best upper-undergraduate/graduate engineering hydrology text available. Like all textbooks, it is beginning to show its age because technology is not stagnant. But its descriptions of core concepts and the application thereof remains top notch.

  World's Furthest Leaning Tower
Posted by: yakwetu - 06-10-2010, 03:40 PM - Forum: Free Discussion - No Replies

World's Furthest Leaning Tower

[Image: info.png]
When it comes to leaning, Italy's Leaning Tower of Pisa can no longer claim to going the furthest.
That honor goes to the Capital Gate building in Abu Dhabi, which was recently certified as being the "World's Furthest Leaning Man-made Tower" by Guinness World Records, according to reports. The building leans at 18 degrees, which is nearly five times that of the Tower of Pisa, which leans at 4 degrees.
However, unlike the Tower of Pisa, the 35-story, 525-foot Capital Gate tower was built to lean 18 degrees westward. So, how did they do it? According to Abu Dhabi National Exhibitions Company, who developed the tower, the building's floor plates are stacked vertically until the 12th floor, after which point they are "staggered over each other by between 300mm to 1400mm." ADNEC says Capital Gate also features "the world's first known use of a 'pre-cambered' core, which contains more than 15,000 cubic meters of concrete reinforced with 10,000 tons of steel."
The building, which boasts on its website that it is "designed to provide no symmetry so it amazes inside and outside," is being touted as an iconic tower for the Emirates' capital, symbolizing the city's vision of the future. "Capital Gate is a landmark development for Abu Dhabi and with this recognition the tower takes its place among the world's great buildings. It is a signature building which speaks of the foresight of the emirate," ADNEC's Chairman Sheikh Sultan Bin Tahnoon Al Nahyan said in a statement.
The United Arab Emirates is no stranger to signature buildings, having unveiled the world's tallest skyscraper, the Burj Khalifa, in Dubai in January. The Capital Gate tower is scheduled to be completed later this year
