Subject: Query on Subset Selection
I am looking for a MATLAB code that implements subset selection in
regression (i.e. least squares + QR with column pivoting, or other
methods). Can you help me send this query?
At the same token, can someone direct me to a survey of numerical algorithms
for the subset selection problem? My data are somewhat specific and do not
fall into the category of the "classical" forward/backward stepwise regression,
as well as the recent LASSO/LARS methods.
Thanks,
Oren

Subject: Lognormal-Gaussian Spectral Density Relationship
I'm looking for the exact analytical relationship, if any, between the
spectral density of a Gaussian and log-normal stationary random process. If
V(x) is gaussian I let U(x) = ln(V(x)). I know the relationship between the
correlation functions, but when I come to take the Fourier transform of
those correlation functions the integrals are tricky to evaluate
analytically (I tried the case of an exponential correlation function).
So my question is the following: Is there any general relationship between
the spectral densities of a Gaussian and its lognormal transform? And more
specifically is there at least some example of correlation functions for
which an analytical relationship between the spectral densities has been
derived?
Many thanks for any help or suggestion.
Best regards,

Subject: New SIAM Series, Fundamentals of Algorithms
Call For Manuscripts
SIAM Series on Fundamentals of Algorithms
SIAM is pleased to announce a new series, Fundamentals of Algorithms,
and the first book in the series, _Solving Nonlinear Equations with
Newton's Method_, by C. T. Kelley.
The goal of the Fundamental of Algorithms series is to provide a
collection of short user-oriented books on state-of-the-art numerical
methods. Written by experts, the books will provide readers with
sufficient knowledge to choose an appropriate method for an
application and understand the method's strengths and limitations. The
books will cover a range of topics drawn from numerical analysis and
scientific computing. The intended audience is researchers and
practitioners using the methods, and upper level undergraduates
in mathematics, engineering, and computational science.
What will distinguish a book in this series is the emphasis on
explaining how to best choose a method, algorithm or software to solve
a specific type of problem, and describing when a given method works
or fails. The theory behind a numerical method will be presented at a
level accessible to the practitioner. The books will contain guidance
to help the reader troubleshoot solvers and interpret results. MATLAB
is the preferred language for codes presented since it can be used
across a wide variety of platforms and is an excellent environment for
prototyping, testing, and problem solving.
The first book in the series, _Solving Nonlinear Equations with
Newton's Method_ by C. T. Kelley, is an 104-page user-oriented guide to
using Newton's method to solve nonlinear equations. Through
algorithms in pseudo-code, practical examples, and MATLAB codes, the
author shows how the user can choose an appropriate Newton-type method
to solve a nonlinear system. Treated are Newton, Newton-Krylov, and
Broyden methods, their weaknesses and strengths, and their
implementation. MATLAB codes for the solvers are listed in the book
and available over the Web.
In launching this series SIAM hopes to publish guides to numerical
algorithms that are readily accessible to practitioners, contain
practical advice not readily found elsewhere, and are accompanied by
understandable codes implementing the algorithms.
Possible topics for the series include, but are not limited to:
quadrature/numerical integration
random number generation
structured linear systems (Toeplitz, Hankel, Vandermonde,...)
Monte-Carlo algorithms for simulation
linear least squares problems
algebraic Riccati equations
stochastic differential equations
large, sparse eigenvalue problems
semidefinite optimization
the fast Fourier transform
discrete ill-posed problems
multigrid methods
visualization

New from Princeton University Press
Markov Processes from K. Ito's Perspective (AM-155)
Daniel W. Stroock
http://pup.princeton.edu/titles/7566.html
Kiyosi Ito's greatest contribution to probability theory may be his
introduction of stochastic differential equations to explain the
Kolmogorov-Feller theory of Markov processes. Starting with the geometric
ideas that guided him, this book gives an account of Ito's program.
The book should be accessible to readers who have mastered the essentials of
modern probability theory and should provide such readers with a reasonably
thorough introduction to continuous-time, stochastic processes.

Subject: New Book on Finite Element Methods for Incompressible Viscous Flow
New Book Announcement
Handbook of Numerical Analysis
Volume IX: Numerical Methods for Fluids (Part 3)
ISBN: 0-444-51224-1
Publisher: North-Holland, Amsterdam,
Volume Author:
Roland Glowinski, University of Houston, Houston, TX, USA
Article Title: Finite Element Methods for Incompressible
Viscous Flow
Series edited by
P.G. Ciarlet, Universite Pierre et Marie Curie, Paris, France
J.L. Lions (deceased), College de France, Paris, France
Description:
This book size article is dedicated to the numerical simulation
of unsteady incompressible viscous flow modeled by the
Navier-Stokes equations, or by non-Newtonian variants of them.
In order to achieve this goal the author has developed a
methodology based on the following tools:
(i) Time discretization by operator splitting schemes such as
Peaceman-Rachford's, Doug las-Rachford's, Marchuk-Yanenko's,
Strang's symmetrized, and the so-called theta-scheme.
(ii) Projection methods (in L2 or H1) for the treatment of the
incompressibility condition div u = 0.
(iii) Treatment of the advection by: either a centered scheme
leading to linear or nonlinear advection-diffusion problems
solved by least squares/conjugate gradient algorithms, or to
a linear wave-like equation well suited to finite element
based solution methods.
(iv) Space approximation by finite element methods such as
Hood-Taylor and Bercovier-Pironneau, which are relatively
easy to implement.
In addition to the above topics the article contains detailed
discussions of conjugate gradient algorithms, least-squares
methods for boundary value problems which are not equivalent
to problems of the Calculus of Variations, Uzawa-type algorithms
for the solution of saddle-point problems, embedding/fictitious
domain methods for the solution of elliptic and parabolic problems.
Many computational methods discussed in this article apply also
to non-CFD problems although they were mostly designed for the
solution of flow problems. Included among the topics rarely seen,
so far, in book form are: the direct numerical simulation of
particulate flow, computational methods for flow control and
splitting methods for visco-plastic flow. Most methods discussed
in this article are illustrated by the results of numerical
experiments, including the simulation of three-dimensional flow.
Due to their modularity the methods described in this article are
relatively easy to implement, proven by the fact that several
practitioners in various institutions have been able to use them ab
initio for the solution of complicated flow, and other, problems.

2003 AFOSR Workshop
2nd Announcement and Update
Advances and Challenges in Time-Integration of PDE's
www.dam.brown.edu/AFOSR03Workshop.html
August 18-20, 2003
Brown University, RI, USA
As methods for spatially representing solutions to partial
differential equations mature, the current methods for temporal
integration emerge as a bottleneck in many areas of large scale
computational science. This is of particular concern as the
emphasis in many applications and recent technologies requring
fully dynamic modeling over extended time periods.
It is the purpose of the workshop to focus on the above mentioned
issues in more detail and, by bringing together experts in various
fields, initiate a discussion on how to effectively address these
significant challengdes.
The format of the workshop will be as a number of invited lectures.
These lecture are intended to delineate the problems encountered
as well as presenting a variety of existing and emerging time-
integration techniques. It will be a priority to attempt to
understand the advantages and limitation of the different
techniques to suggest directions in which research should be
directed.

PARAMETRIC STUDIES OF MULTIPLE TUNNELLING USING THE NATIONAL HPC RESOURCES
Applications are invited for a two-year EPSRC funded post to work on
geotechnical engineering studies of multiple tunneling problems. The post
is available from November 1st 2003 for a fixed two-year term. The
successful candidate will be based at the School of Engineering of the
University of Durham, and will be collaborating closely with co-workers in
the Department of Mathematics of the University of Strathclyde in Glasgow.
The person appointed will also receive training in the use of the National
High Performance Computing (HPC) resources housed at the University of
Manchester.
Following an EPSRC call for proposals to introduce new users to high-end
computing, funds have been awarded to carry out a number of 3D parametric
studies of an important set of problems in geotechnics that are
under-researched because of the difficulties of running 3D FE analyses in
geotechnics. We will be studying the effects of the construction and
stability of multiple tunnels in soft ground. These are difficult problems
to solve except for in a few situations that can be modelled in
two-dimensions. We will be using the HPC resources to carry out detailed
parametric studies that could not be completed on serial machines.
The objectives of the project are:
1. to develop an existing F90 finite element code for use on the parallel
hardware available within national HPC resources;
2. to incorporate new solution techniques from an existing EPSRC CEM
project into the parallel environment
3. to use the parallel code to investigate the surface deformations
arising from multiple tunnelling schemes, and to investigate their
stability during construction.
Applicants should have a Doctorate in Civil or Mechanical Engineering,
Applied Mathematics or Applied Computer Science (or equivalent research
experience) and possess expertise in one or more of the following areas:
the development and use of finite element methods for the solution of
PDEs; structural mechanics; numerical linear algebra; numerical methods
in geotechnical engineering. Applicants must have experience of
programming using Fortran 90 or later.
Applications, quoting reference A2239, with a full CV giving the names and
addresses of two academic referees (and copies of any relevant
publications), should be sent to

Subject: Postdoctoral Position at University of California, Berkeley
The Institute for Quantitative Biomedical Research at the University of
California, Berkeley is seeking a postdoctoral fellow with a strong
background in computer graphics, visualization, and scientific
computing. The position will be a one-year term.
The successful candidate will be part of a team that includes
researchers from Lawrence Berkeley National Lab and the University of
California at Davis. The team's mission is to develop new
methods for protein structure prediction. The methods
include a combination of purely computational, based upon optimization
techniques, along with user-guided methods. The user-guided approach
relies upon a software tool, developed by the team, that allows a
researcher to interactively manipulate protein molecules.
The role of the postdoctoral fellow will be to enhance and expand the
interactive manipulation and visualization tool as part of the broader
team effort of improving protein structure prediction in computational
biology. The interactive manipulation and visualization tool is written
in C++, and uses OpenGL as the underlying graphics API, and FLTK as the
GUI API.
Applicants must have a Ph.D. in Computer Science or related field. Some
background in Biology is highly desirable. The candidate should
demonstrate the ability to conduct original and independent research
in a highly collaborative environment. The candidate must have
demonstrable skills, through work history or graduate school projects,
in the following areas: software implementation in C++; use of the
OpenGL graphics API; use of GUI APIs such as FLTK or GTK; design and
development of interactive graphics or visualization software; design
and implementation of shared- or distributed-memory parallel software;
and excellent written communication skills, particularly technical
writing. The candidate must have a highly professional team-oriented
disposition, and is expected to observe project deadlines.
Applicants should submit:
* a curriculum vitae with list of publications (with some reprints or
PhD thesis included), including a summary of recent technical work
experience that meets the above qualifications and which demonstrates a
high degree of technical innovativeness;
* a letter in support to justify the application;
* names and addresses of three references.
