Subject: MOOC on linear algebra (LAFF) offered again

In Spring 2014, we first offered "Linear Algebra: Foundations to
Frontiers" (LAFF) on the edX platform ( LAFF is an
introductory course on linear algebra that links abstractions in
mathematics to abstractions in code. The course targets many
audiences, ranging from novices to those wanting a refresher.

This fall, LAFF is offered as a semester-long course starting August
24. The materials will be pre-released starting August 3 for those
who want to review before the Fall semester starts for courses on
applied and/or numerical linear algebra. The course heavily stresses
partitioning of matrices and vectors and uses our "FLAME notation" to
present algorithms.

For links, details, reviews, notes, videos, and activities, visit There you will also find my "Notes on Numerical
Linear Algebra" which I created for my graduate course on numerical
linear algebra.

Subject: Postdoc Position, NA/Scientific Computing, Charles Univ, Prague

A significant part of progress in scientific computing for solving
large real-world problems naturally stems from new mathematical
approaches. Moreover, the whole process from the problem formulation
through its mathematical description, corresponding analysis, discrete
representation, solving the discretized problem up to verification of
computed results represents a holistic task whose parts cannot be
separated from each other. The solution process typically involves
various and often distant mathematical disciplines connected by the
need to use high performance computational tools. High-performance
computing systems use extreme parallelism in performing
computations. This requires adequate methods, algorithms and
implementations, with emphasize on their theoretical analysis,
investigation of numerical stability, accuracy of computations,
robustness, resilience, and low computational cost. The research of
numerical methods complying with the demands of high-performance
computing will be conducted at the Faculty of Mathematics and Physics,
Charles University in Prague, in the team led by Zdeněk Strakoš and
Miroslav Tůma. Applicants should have a PhD in mathematics or in
computer science, with a background in computational mathematics, in
particular numerical analysis and/or matrix computations.

Subject: PhD Position, Numerical Parameter Identification, TU Darmstadt

The Graduate School of Computational Engineering
( at the Technische Universität Darmstadt
offers one PhD scholarship supervised by Prof. Dr. Winnifried Wollner
in the field of Numerical Parameter Identification

Magnets used for example in particle accelerators to bend the particle
beam contain yokes made of nonlinear or even hysteric materials that
may be premagnetized. To adjust the magnetic field the current must be
precisely controlled. However, the field distribution depends on the
unknown magnetization of the yoke. This is mathematically modeled by a
2D nonlinear parabolic or elliptic partial differential equation with
unknown material distribution. The aim of the PhD project is the
development and realization of techniques for the numerical estimation
of this magnetization to allow for a more precise control of the
resulting magnetic field. The PhD Scholarship is focused on
mathematical methods with a collaboration with electrical
engineering. Applicants ideally have some background knowledge in
numerical methods for PDEs (Finite Elements) and optimization with
PDEs or parameter identification. Formal requirements for the
scholarship are available at

The PhD position is limited to three years and is based on the
guidelines of the German Research Foundation (DFG).

For inquiries, please contact Winnifried Wollner (cf. mail address
below). Candidates should submit a short application including a
cover letter, a CV and their latest grade records within one single
PDF file (5 pages at most) in electronic form to .

Subject: PhD Position, Optimization for Data Assimilation, Univ of Reading, UK

A fully-funded PhD position in Novel Optimization Methods for Data
Assimilation is available at the University of Reading, working with
Amos Lawless and Nancy Nichols in Reading and Coralia Cartis in

Data assimilation is the process of combining observations with a
numerical model in order to estimate the state of a physical
system. It is widely used in many areas of environmental modelling,
for example to estimate the initial conditions for a weather
forecast. In this project recently-developed advanced numerical
optimization methods will be adapted for use in data assimilation for
environmental prediction. In particular, these new methods will be
compared to currently-used methods in a series of problems of
increasing complexity. The performance of the methods will be
investigated computationally and analysed mathematically.

Due to restrictions on the funding this studentship is only open to
UK/EU students.

Subject: PhD Position, Scientific Computing, Loughborough Univ

A PhD studentship funded by Loughborough University is available to
start in October 2016. The project, based in the Department of
Mathematical Sciences at Loughborough University, will focus on the
mathematical and computational modelling of point-of-care water
purification devices. The aim is to set up a robust and reliable
modelling tool that would enable simulation of different working
configurations for the device with a view to optimize its performance
and design. The successful candidate will be expected to develop a
mathematical model of the process of filtration of water through a
porous medium and computational finite element software to simulate
filtration. The model will be validated using experimental data
obtained in the Chemical Engineering Department. The studentship is
for 3 years and it provides a stipend of £14,296 per annum plus
tuition fees at the UK/EU rate for up to three years. International
(non EU) students may apply but will need to find the difference in
fees between those for a 'UK/EU' and 'international' student
themselves. Students will normally need to hold, or expect to gain,
at least a 2:1 degree (or equivalent) in Mathematics, Physics or
Engineering. A relevant Master's degree and/or experience in one or
more of the following will be an advantage: Applied Computational
Mathematics, Computational Mechanics. Interested candidates are
encouraged to contact Dr Marco Discacciati (
