Version 2.0 of the Empirical Gramian Framework "emgr" has been

Empirical gramians can be used for model reduction, system
identification and uncertainty quantification. The empirical
gramian framework provides seven types of empirical gramians
through a uniform interface:

- empirical controllability gramian
- empirical observability gramian
- empirical cross gramian
- empirical approximate cross gramian
- empirical sensitivity gramian
- empirical identifiability gramian
- empirical joint gramian

for (parametrized) linear and nonlinear control systems.

Subject: New Book, Graduate Introduction to Numerical Analysis

New (and different) Graduate text in NA
R.M. Corless & Nicolas Fillion
Graduate Introduction to Numerical Analysis from the point of view of
backward error analysis

Springer, 868pp, $100
Springer “My Copy” soft cover $24.95 where available

This book endeavours to present a unified view of numerical analysis,
using backward error and conditioning for all problems considered in
the book, from polynomial evaluation to PDE. It is aimed at entering
graduate students, who typically have a wide range of backgrounds.

It is quite different to existing textbooks and may take some getting
used to. One of the differences is extensive use of contour integrals
and barycentric interpolation formulae. We hope that the benefits of a
unified point of view for analysis are enough to compensate for the
effort needed to adjust one’s notes in order to teach from it.

Subject: Boundary Integral Equations, UK, May 2014

NAIS Workshop - Boundary Integral Equations Analysis and Computation,
Edinburgh, May 2014

Numerical methods based on boundary integral equations are powerful
tools in a number of engineering applications, in particular in
problems posed in unbounded domains, e.g., acoustic and
electromagnetic direct and inverse scattering. In recent years
ground-breaking work has been done on high-frequency problems, on
time-domain boundary integral equations, stochastic integral
equations, etc. The resulting numerical methods are usually
intrinsically highly accurate, but require deep analysis, refined
algorithms, and the power of high performance computing to make them
competitive in applications. This conference will bring together a mix
of renowned UK and international speakers and young UK researchers
from the fields of numerical analysis and engineering.

Subject: Challenges in Mathematical Biology, UK, May 2014

NAIS International Workshop on Numerical Methods and Emerging
Computational Challenges in Mathematical Biology, Dundee, May 2014.

The past few decades have witnessed exciting developments in all areas
of Mathematical Biology leading to very challenging computational
questions related to the multiscale nature of the biological
problems. To address these challenges, one requires innovative
numerical methods at the cross-interface between
atomistic-to-continuous, heterogeneous multiscale methods, and domain
decomposition techniques that would facilitate efficient computational
implementations. This workshop aims to bring together leading experts
and young researchers in both Numerical Analysis and Mathematical
Biology areas. The goal is to identify suitable numerical approaches
that would be able to address the computational challenges arising in
biological modelling. It is hoped that this will enhance the existing
cross-fertilization between these two areas of mathematics and will
bring about new ideas for the development of novel, fast, and
potentially parallelizable numerical solvers, able to answer urgent
questions in complex biological and medical problems.

Subject: Challenges in medical imaging, UK, May 2014

NAIS Workshop - Challenges in medical imaging: numerics, high
performance computing, inverse problems, Glasgow, May 2014.

The aim of this workshop is to gather specialists on Numerical
Methods, High Performance Computing, Inverse Problems, Microwave
Imaging. Microwave Tomography is a novel, early stage development way
of imaging with a number of potentially attractive medical
applications. In particular,Microwave imaging (MI) of the human head
(used especially in the detection of strokes) has attracted a
significant research interest in the latest years mainly oriented on
the design of antenna elements and arrays, imaging using ultra-wide
band radar techniques, and real-time monitoring. The accurate
reconstruction of the properties of the head tissues (which allow the
differentiation between ill and healthy ones) relies heavily on
precise mathematical and numerical modeling (involving inverse
problems, high order approximation methods and fast solution
techniques of large scale problems) of the interaction between
electromagnetic waves and the human body in high frequency regime.

performance computing (HPC) environment is the focus of this
workshop. Recent developments in numerical algorithms for partial
differential equations with multiple spatial or temporal scales will
be discussed, including numerical homogenization methods, domain
decomposition methods, multilevel Monte Carlo methods, time stepping
algorithms for multiscale flow problems. Challenges in the

NAIS Workshop - Spatial Statistics and Uncertainty Quantification
on Supercomputers, Bath, May 2014.

Societal and environmental challenges, not least the potential dangers
of climate change, have lead to a surge in the interest and in the
development of novel statistical tools to deal with very big data sets
on the one hand and of efficient uncertainty quantification (UQ)
methods for complex engineering applications on the other. There are
two main aims for this meeting. The first aim is to bring together key
researchers from statistics and from applied mathematics working in
spatial statistics and in UQ, but approaching similar questions from
often quite different angles. The second aim is to go beyond the
discussion and analysis of algorithms applied to toy problems, and to
instead focus on real, large scale applications and on the scalability
of novel statistical and UQ tools on modern supercomputers.

Subject: Multiscale Computational Methods, UK, Jun 2014

NAIS Meeting/Tutorial - MCM3: Multiscale Computational Methods in
Materials Modelling, Edinburgh, June 2014

Whilst the scope of the meeting is broad (spanning quantum, classical
and mesoscale techniques) the emphasis will be on mathematical
approaches, stochastic numerical algorithms and parallel computing
issues. The goal is to seek points in common among scale-bridging
techniques in different modelling regimes. The experience of the
participants is also expected to be quite broad, with chemists,
engineers, physicists and mathematicians all presenting talks on both
theoretical and applied topics. The tutorial will feature instruction
in the use of molecular modelling tools (especially the LAMMPS
software package, for simulation of materials models). The tutorial
will also feature high level talks on algorithms and modelling issues
related to materials simulation. Graduate students and postdoctoral
researchers are particularly encouraged to attend both the tutorial
and the meeting.

Subject: Automated Code Generation, UK, Jul 2014

NNAIS Workshop - Automated Code Generation, Edinburgh, July 2014

Automated code generation techniques are seeing diverse and increasing
applications in scientific research and engineering. These approaches
divide the details of program or model design from the details of the
low-level implementation. This provides a separation between
application specific details, such as the choice and design of
numerical algorithms or discretisations, from optimisation and
hardware specific details, such as low-level optimisation and
parallelisation. Automated code generation can therefore enable the
rapid development of complex numerical models and algorithms, while
maintaining efficiency and portability on existing or developing
computer architectures. This one day workshop on automated code
generation will bring together speakers with expertise in the areas of
optimised discrete Fourier transforms, parallel computing on Graphics
Processing Units (GPU), portable automated code generation techniques
on high-performance computing resources, and high-level algorithmic

problems). The student will finalise a thesis proposal at the end of
year 1, and will work on PhD research in years 2-4 under the mentoring
of a principal supervisor and a co-supervisor.

There will be support for student-organised events as well as travel.

Expressions of interest together with a short CV and a statement of
courses and examination results should be sent to Prof Paul Milewski,
preferably via email: Our intention is to
review applications as rapidly as possible in every case.
