In December 2018, the Czech Association for Mechanics and the Union of
Czech Mathematicians and Physicists again awarded the I. Babuska Prize
for the best work in computational mechanics and computational
mathematics submitted by students and young scientists. The Prize
winner for 2018 is Dr Jan Kopacka from the Faculty of Mechanical

Subject: Developing Countries, Resources Online, IFORS

The aim of the IFORS Developing Countries On-Line Resources page is to
offer the OR worker all publicly-available materials on the topic of
OR for Development. It also aims to provide a venue for people who are
working in the area to share their completed or in-process work, learn
from others, and stimulate comments and discussions on the
work.Regarding IFORS Developing Countries OR resources website, its
regular updates - and your possible submission of "free" (not
copyright protected) material, you might occasionally visit

"Operational Research" (OR) is the discipline of applying advanced
analytical methods to help make better decisions. By using techniques
such as problem structuring methods and mathematical modelling to
analyze complex situations, Operational Research gives executives the
power to make more effective decisions and build more productive

The International Federation of Operational Research Societies (IFORS; is an almost 60-year old organization which is
currently composed of 51 national societies.Regional Groups of IFORS
are:ALIO (The Latin American Ibero Association on Operations
Research), APORS (The Association of Asian-Pacific Operational
Research Societies), EURO (The Association of European Operational
Research Societies), NORAM (The Association of North American
Operations Research Societies). IFORS conferences are taking place
every three years; IFORS 2017 has been successfully celebrated in
Quebec City, Canada.

Subject: New Book, Linear Algebra and Learning from Data

Linear Algebra and Learning from Data
Gilbert Strang

This is a textbook to help readers understand the steps that lead to
deep learning. Linear algebra comes first---especially singular
values, least squares, and matrix factorizations. Often the goal is a
low rank approximation A = CR (column-row) to a large matrix of
data---to see its most important part. This uses the full array of
applied linear algebra, including randomization for very large

Then deep learning creates a large-scale optimization problem for the
weights solved by gradient descent or better stochastic gradient
descent. Finally, the book develops the architectures of fully
connected neural nets and of Convolutional Neural Nets (CNNs) to find
patterns in data. Audience: This book is for anyone who wants to
learn how data is reduced and interpreted by and understand matrix
methods. Based on the second linear algebra course taught by Professor
Strang, whose lectures on the training data are widely known, it
starts from scratch (the four fundamental subspaces) and is fully
accessible without the first text.

Subject: PhD Position, Univ of Reading, UK

A PhD is available in "Novel physical and numerical methods for
simulating water and heat transfer in land surface models" at the
University of Reading, UK. This is a fully funded 4 year NERC CASE
studentship with the UK Met Office (UKMO). Due to restrictions funding
is available to UK/EU students only.

Land surface models, such as UKMO's Joint UK Land Environment
Simulator (JULES), describe unsaturated flow in soils through an
implicit form of the Richards partial differential equation. Solutions
to such a highly non-linear equation inevitably leads to numerical and
accuracy issues which impact on their hydrological performance. This
project concerns the implementation and testing of two new explicit
unsaturated zone flow solution methods into JULES which use a
velocity-based PDE for the depth in terms of the water content, either
through a hodograph transformation or local mass conservation. The
student will extend both approaches to account for heat flow.

Applicants should hold or expect to gain a minimum of a 2:1 Degree or
equivalent in Mathematics or a suitable Physical Science.

To apply please submit an application for a PhD in Environmental
Science at
to-apply.aspx, quoting the reference 'GS18-29' in the 'Scholarships
applied for' box which appears within the Funding Section of your on-
line application.

Application deadline is 15th February, 2019. For further information
