Subject: New book: Solving PDEs in C++

Solving PDEs in C++
SIAM, Computational Science and Engineering 1, Jan. 2006

by Yair Shapira
Computer Science dept., Technion, Haifa, Israel

http://www.ec-securehost.com/SIAM/CS01.html

"There are dozens of excellent books on C++ and object-oriented programming, but very few of them put the language 
into the perspective of scientific computing. The introductory part of the present book acts as a language introduction, 
while the main contents focus on how C++ can be used to implement numerical algorithms. I would say that this is a 
long-awaited type of textbook in the scientific computing community."
    -- Hans Petter Langtangen, Professor, Simula Research Laboratory and University of Oslo, Norway.

This comprehensive book not only introduces the C and C++ programming languages but also shows how to use them 
in the numerical solution of partial differential equations (PDEs). It leads the reader through the entire solution process, 
from the original PDE, through the discretization stage, to the numerical solution of the resulting algebraic system. The 
well-debugged and tested code segments implement the numerical methods efficiently and transparently. Basic and 
advanced numerical methods are introduced and implemented easily and efficiently in a unified object-oriented 
approach.

The high level of abstraction available in C++ is particularly useful in the implementation of complex mathematical 
objects, such as unstructured mesh, sparse matrix, and multigrid hierarchy, often used in numerical modeling. This 
book introduces a unified approach for the implementation of these objects. The code segments and their detailed 
explanations clearly show how easy it is to implement advanced algorithms in C++.  

"Solving PDEs in C++" contains all the required background in programming, PDEs, and numerical methods; only an 
elementary background in linear algebra and calculus is required. Useful exercises and solutions conclude each chapter. 
For the more advanced reader, there is also material on stability analysis and weak formulation. The final parts of the 
book demonstrate the object-oriented approach in advanced applications.

Audience
The book is written for researchers, engineers, and advanced students who wish to increase their familiarity with 
numerical methods and to implement them in modern programming tools. 
"Solving PDEs in C++" can be used as a 
textbook in courses in C++ with applications, C++ in engineering, numerical analysis, and numerical PDEs at the 
advanced undergraduate and graduate levels.  Because it is self-contained, the book is also suitable for self-study by 
researchers and students in applied and computational science and engineering.

The work will cover both aspects of numerical mathematics and of theoretical
physics, and will be carried out in a joint interdisciplinary collaboration
between mathematics and physics.

Applicants must hold a PhD, and should be experienced in numerical analysis,
ideally optimal control theory, and possess some background in physics.  They

"This book is quite complete and self contained.  It is up to date and covers
a wide range of topics, all of which are pertinent.  The presentation seems
accessible to beginners, and yet it also has enough advanced material to be of
interest to experts."
    -- Todd Arbogast, Professor, Institute for Computational Engineering and
       Sciences, University of Texas, Austin.

"This is a well-structured book covering a field that, as far as I am aware,
has not already been dealt with.  It will be an excellent supplement to
existing books."
    -- Rainer Helmig, Professor, Institute of Hydraulic Engineering, University of
       Stuttgart, Germany.

"This book offers a fundamental and practical introduction to the use of
computational methods, particularly finite element methods, in the simulation
of fluid flows in porous media.  It is the first book to cover a wide variety
of flows, including single-phase, two-phase, black oil, volatile,
compositional, nonisothermal, and chemical compositional flows in both
ordinary porous and fractured porous media.  In addition, a range of
computational methods are used, and benchmark problems of nine comparative
solution projects organized by the Society of Petroleum Engineers are
presented for the first time in book form."

"Computational Methods for Multiphase Flows in Porous Media reviews multiphase
flow equations and computational methods to introduce basic terminologies and
notation.  A thorough discussion of practical aspects of the subjects is
presented in a consistent = manner, and the level of treatment is rigorous
without being unnecessarily abstract.  Each chapter ends with bibliographic
information and = exercises."

FIRST ANNOUNCEMENT and CALL FOR PAPERS

This international conference is a joint edition of the 6th Scale Space and the
4th VLSM and it will be a first attempt to bring together two different
communities with joint research interests, the one of scale space analysis and
the one of variational, geometric and level set methods and their applications
in image interpretation and understanding. Such a conference would serve
several purposes: international researchers and students would be exposed to
state-of-the-art research on mathematical, physical and computational aspects
of imaging, computer vision, graphics and inverse problems with applications.

TOPICS
Linear Scale-Space Theory, Nonlinear Diffusion, Morphological Image Processing,
Differential Geometry & Geometric Flows, PDE-Level Set, Langrangian &
Variational Methods,Statistical Methods & Energy-minimization Approaches

This conference deals with all aspects of these aspects, including
- theoretical foundations
- efficient numerical methods,
- applications in image and surface processing and computer vision
(image restoration, shape analysis, grouping, segmentation, motion, stereo,
registration)
- applications in other fields  (biomedical applications, industrial inspection,
security).

IMPORTANT INFORMATIONS
It is planned to publish the proceedings in the Springer Lecture Notes in
Computer Science Series. Selected papers will appear in a special issue of the
International Journal of Computer Vision.
Prospective authors are encouraged to submit manuscripts of not more than 12
pages in Springer LNCS format by October 23rd, 2006.

Subject: Ph.D. position at RICAM

In the framework of a three-year research project on

"Algebraic Multigrid and Multilevel Methods for Vector-Field Problems",

funded by the Austrian Science Foundation, a position for a
Ph.D. student is available at the Johann Radon Institute for
Computational and Applied Mathematics (RICAM) from the
beginning of 2007.

Good knowledge of C++ is required. Familiarity with finite element
and (algebraic) multigrid methods is desirable. Some knowledge of 
electromagnetics is advantageous. 

Informal enquiries can be made to Dr. Johannes Kraus at:
johannes.kraus@oeaw.ac.at.

A complete application including academic records (copies of
relevant documents, a statement about scientific interest and
achievements related to the master thesis) should be sent to

 Dr. Johannes K. Kraus
 Johann Radon Institute
 Austrian Academy of Sciences
 Altenbergerstrasse 69
 A-4040 Linz Austria
 Austria

Alternatively, the application material can be sent by email to 
johannes.kraus@oeaw.ac.at
