Subject: Freely available software for the solution of linear algebra problems

We are planning to update the survey of freely available software for
the solution of linear algebra problems. The current version of the
survey can be found at:
http://www.netlib.org/utk/people/JackDongarra/la-sw.html

The aim is to put in "one place" the source code that is freely
available for solving problems in numerical linear algebra,
specifically dense, sparse direct and iterative systems and sparse
iterative eigenvalue problems. Please send Ali Charara [log in to unmask]
updates and corrections. We will post a note on the na-digest when the
new list is available.

Thanks,
Jack Dongarra and Ali Charara

Subject: New Book, Applied Linear Algebra, Second Edition

Applied Linear Algebra, second edition
by Peter J. Olver and Chehrzad Shakiban
Undergraduate Texts in Mathematics, Springer, New York, 2018

The second edition of our undergraduate text is now in print, both e-
book and hardcover (and much more affordable).  Ordering information
can be found at https://www.springer.com/us/book/9783319910406.  You
can check if you already have electronic access through your
Institution here:
https://link.springer.com/book/10.1007%2F978-3-319-91041-3

In addition to revising and reordering existing material - that
includes basic numerical linear algebra: solution of equations; inner
products, norms, and Gram-Schmidt; least squares, interpolation, and
approximation; iterative methods; numerical computation of eigenvalues
and singular values; and much more - new material has been added:
Krylov subspace methods, including Conjugate Gradients, FOM, and
GMRES; Principal Component Analysis and its relation to SVD; and
wavelets, which supplements the existing introduction to the DFT/FFT.

This textbook develops the essential tools of linear algebra, with the
goal of imparting technique alongside contextual understanding.
Applications go hand-in-hand with theory, each reinforcing and
explaining the other.  Providing an extensive treatment of essential
topics such as Gaussian elimination, inner products and norms, and
eigenvalues and singular values, this text can be used for an in-depth
first course, or an application-driven second course in linear
algebra. In this second edition, applications have been updated and
expanded to include numerical methods, dynamical systems, data
analysis, and signal processing, while the pedagogical flow of the
core material has been improved.  The first author's undergraduate
text, Introduction to Partial Differential Equations, , is an ideal
companion volume, and a natural extension of the linear mathematical
and numerical methods developed here.

Subject: Machine Learning and Computational Methods for Geoscience, USA, Oct 2018

Novel computational and machine learning techniques are emerging as
important research topics in many geoscience domains. In this
workshop, we bring together researchers from geosciences and
computational science to discuss recent advances and challenges
arising from the design and application of computational
techniques. Different geoscience applications often share similar
computational techniques. However, there are not many opportunities
for researchers from different domains to share their experiences in
designing and using computational tools and methods.  Through this
workshop, we intend not only to investigate those common computational
methods in depth, but also to promote potential future
applications. The purpose of our workshop is to (1) demonstrate the
importance of computational methods in understanding and analyzing the
real problems arising in a broad array of geosciences applications,
such as seismology, topography, hydrology, and remote sensing; (2)
foster communication and interaction between geoscience researchers
and computational scientists; and (3) identify critical research
topics and potential solutions. The main research topics of our
workshop will include but not be limited to statistical and machine
learning techniques, inverse problems, and optimization. This workshop
will also include an evening poster session. More information and

Subject: Special Issue Call, Optimization and Engineering (OPTE)

OPTE Special Issue: TriPod-MOPTA 2018 on Energy and Optimization
Submission Due Date: October 30, 2018

This call aims at publishing research work that showcases the
interactions between Optimization and Engineering to address important
problems arising in the Energy sector. The call encourages submissions
from speakers at the upcoming TriPod-MOPTA 2018, but is open to
submissions from any interested authors. The call is open to all types
of papers, including theoretical, applied, and algorithmic articles,
as well as articles that combine these features.

The rapid and imperative changes in the Energy sector have created a
wide range of challenges that are being addressed by a combination of
Engineering and Optimization techniques. For example, consider the use
of convex relaxations to obtain near-optimal alternating current
optimal power flow (ACOPF) solutions, or for gas distribution network
problems; the use of multi-level optimization to address commodity
pricing problems, integration of renewable energy sources (RES) into
electricity markets, or to immunize a commodity network against
potential attacks; the use of uncertainty optimization techniques to
address challenges related to the use of RES, immunize commodity
networks against catastrophic events, and obtain robust equilibrium
commodity prices that take into account uncertainty in commodity
production or demand; the development of improved mathematical
formulations and optimization solution methods, to address large-scale
Energy related problems; among many other interesting research
directions that are being explored towards the goal of designing
commodity networks that are 'smart', interconnected, efficient,
reliable, resilient, and environmentally responsible.  Beyond the
study of individual commodity networks, nowadays, very interesting
research addresses the challenging problem of studying the interaction
between different commodity networks such as electricity, gas, and
water networks, as well as the interaction of these networks with
communication and transportation networks.

Please submit to the Optimization and Engineering (OPTE) journal at
https://www.springer.com/mathematics/journal/11081 and select special
issue 'SI: TriPod-MOPTA 2018'. All sub- missions must be original and
may not be under review by another publication.  Interested authors
should consult the journal's "Instructions for Authors", at
http://www.springer.com/ mathematics/journal/11081.  All submitted
papers will be reviewed on a peer review basis.
