"This volume contains the articles presented at the 20th International Meshing Roundtable (IMR) organized, in part, by Sandia National Laboratories and was held in Paris, France on Oct 23-26, 2011. This is the first year the IMR was held outside the United States territory. Other sponsors of the 20th IMR are Systematic Paris Region Systems & ICT Cluster, AIAA, NAFEMS, CEA, and NSF. The Sandia National Laboratories started the first IMR in 1992, and the conference has been held annually since. Each year the IMR brings together researchers, developers, and application experts, from a variety of disciplines, to present and discuss ideas on mesh generation and related topics. The topics covered by the IMR have applications in numerical analysis, computational geometry, computer graphics, as well as other areas, and the presentations describe novel work ranging from theory to application.

"Proyek pembangunan world trade center 3 (WTC 3) menggunakan pondasi pile raft lengkap dengan 5 lantai basement dan retaining structure yang mengelilinginya berupa secant pile dia. 800 mm untuk menopang 44 lantai bangunan tower serta 4 lantai podium, desain pondasi pile raft tersebut belum meperhitungkan keberadaan retaining structure serta kekakuan dari konstruksi basement. Sejatinya pondasi pile raft, retaining structure & element struktur basement terintegrasi dan bekerja secara bersama-sama dalam meneruskan beban struktur atas ke masa tanah dibawah pondasi.
Pada penelitian ini telah dilakukan pengujian melalui analisa numerik dengan menggunakan software GTS Midas terhadap sejumlah model dan ditemukan bahwa keberadaan retaining structure dan elemen struktur basement dapat mengurangi settlement (maksimum settlement serta differential settlement) dan internal force (bending moment & shear force) yang terjadi pada pondasi pile raft melalui mekanisme pengekangan ujung raft dan masa tanah dibawah raft serta transfer beban vertikal dari raft ke retaining structure sehingga sebagin beban vertikal dipikul oleh retaining structure. Efek pengekangan dan mekanisme transfer beban retaining structure dapat bekerja efektif pada rasio Dw/Dt < 1.3 serta pada sistem pondasi partially pile raft.

The construction of world trade center 3 (WTC 3) project are using pile raft as a foudation to support 44 floors of tower building and 4 floors of podium building. This foundation is integrated with five floors of basement and retaining structure. The type of retaining structure used is secant pile with 800 mm diameter in which the position of retaining structure lies on the circumferences of the basement. The original design of the pile raft foundation are not consider the existence of retaining structure and the structural element stiffness of basement likes column, beam etc. In fact that pile raft, basement element structure and retaining structure are integrated and working together in transfer load from upper structucture to soil.
In this reasearch it was examine a number of model with numerical analysis using GTS midas software and it was known that the interaction of retaining structure and basement element structure can reduce settlement (Maximum settlement and differential settlement) and internal force (bending moment & shear force) on pile raft foundation by two mechanism. The first mechanism is the retaining structure and basement element structure can restraining the end of raft and the second mechanis is vertical load transfer from raft to retaining structure. Both of the mechanisms are effective for rasio Dw/Dt less than 1.3 and for partially pile raft.

"These proceedings were prepared in connection with the international conference Approximation Theory XIII, which was held March 7–10, 2010 in San Antonio, Texas. The conference was the thirteenth in a series of meetings in Approximation Theory held at various locations in the United States, and was attended by 144 participants. Previous conferences in the series were held in Austin, Texas (1973, 1976, 1980, 1992), College Station, Texas (1983, 1986, 1989, 1995), Nashville, Tennessee (1998), St. Louis, Missouri (2001), Gatlinburg, Tennessee (2004), and San Antonio, Texas (2007).
Along with the many plenary speakers, the contributors to this proceedings provided inspiring talks and set a high standard of exposition in their descriptions of new directions for research. Many relevant topics in approximation theory are included in this book, such as abstract approximation, approximation with constraints, interpolation and smoothing, wavelets and frames, shearlets, orthogonal polynomials, univariate and multivariate splines, and complex approximation."

"This book is for students following an introductory course in numerical methods, numerical techniques or numerical analysis. It introduces MATLAB as a computing environment for experimenting with numerical methods. It approaches the subject from a pragmatic viewpoint, theory is kept at a minimum commensurate with comprehensive coverage of the subject and it contains abundant worked examples which provide easy understanding through a clear and concise theoretical treatment. This edition places even greater emphasis on ‘learning by doing’ than the previous edition."

"This book is a snapshot of current research in multiscale modeling, computations and applications. It covers fundamental mathematical theory, numerical algorithms as well as practical computational advice for analysing single and multiphysics models containing a variety of scales in time and space. Complex fluids, porous media flow and oscillatory dynamical systems are treated in some extra depth, as well as tools like analytical and numerical homogenization, and fast multipole method."

"Beyond simulation and algorithm development, many developers increasingly use MATLAB even for product deployment in computationally heavy fields. This often demands that MATLAB codes run faster by leveraging the distributed parallelism of Graphics Processing Units (GPUs). While MATLAB successfully provides high-level functions as a simulation tool for rapid prototyping, the underlying details and knowledge needed for utilizing GPUs make MATLAB users hesitate to step into it. Accelerating MATLAB with GPUs offers a primer on bridging this gap.
Starting with the basics, setting up MATLAB for CUDA (in Windows, Linux and Mac OS X) and profiling, it then guides users through advanced topics such as CUDA libraries. The authors share their experience developing algorithms using MATLAB, C++ and GPUs for huge datasets, modifying MATLAB codes to better utilize the computational power of GPUs, and integrating them into commercial software products. Throughout the book, they demonstrate many example codes that can be used as templates of C-MEX and CUDA codes for readers? projects.

"Flow control and optimization has been an important part of experimental flow science throughout the last century. As research in computational fluid dynamics (CFD) matured, CFD codes were routinely used for the simulation of fluid flows. Subsequently, mathematicians and engineers began examining the use of CFD algorithms and codes for optimization and control problems for fluid flows. The marriage of mature CFD methodologies with state-of-the-art optimization methods has become the center of activity in computational flow control and optimization.
Perspectives in Flow Control and Optimization presents flow control and optimization as a subdiscipline of computational mathematics and computational engineering. It introduces the development and analysis of several approaches for solving flow control and optimization problems through the use of modern CFD and optimization methods. The author discusses many of the issues that arise in the practical implementation of algorithms for flow control and optimization, such as choices to be made and difficulties to overcome. He provides the reader with a clear idea of what types of flow control and optimization problems can be solved, how to develop effective algorithms for solving such problems, and potential problems to be aware of when implementing the algorithms.
This book is written for both those new to the field of control and optimization as well as experienced practitioners, including engineers, applied mathematicians, and scientists interested in computational methods for flow control and optimization. Both those interested in developing new algorithms and those interested in the application of existing algorithms should find useful information in this book."

"This book treats the numerical analysis of finite element computational fluid dynamics. Assuming minimal background, the text covers finite element methods; the derivation, behavior, analysis, and numerical analysis of Navier-tokes equations; and turbulence and turbulence models used in simulations. Each chapter on theory is followed by a numerical analysis chapter that expands on the theory. The chapters contain numerous exercises."
