**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,

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.

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.
