Subject: New Book, Numerical Analysis Using R: Solutions to ODEs and PDEs

This book presents some of the latest numerical solutions to initial
value problems and boundary value problems described by ODEs and
PDEs. The author offers practical methods that can be adapted to solve
a wide range of problems which are illustrated in the increasingly
popular open source computer language R, which allows integration with
more statistically based methods. The book begins with standard
techniques, followed by an overview of high resolution 'flux limiter'
and 'weighted essentially non-oscillatory' (WENO) methods to solve
problems with solutions exhibiting high gradient phenomena. Meshless
methods using radial basis functions (RBFs) are then discussed in the
context of scattered data interpolation and the solution of PDEs on
irregular grids. Three detailed case studies demonstrate how numerical
methods can be used to tackle very different complex problems. With
its focus on practical solutions to real-world problems, this book
will be useful to students and practitioners in all areas of science
and engineering, especially those using R. All code are available for
- Practical solutions to ODEs and PDEs using computer code.
- Overviews of 'high resolution' schemes and meshless methods.
- Case studies illustrating the use of real-world numerical analysis.

Table of Contents: 1. ODE integration methods. 2. Stability analysis
of ODE integrators. 3. Numerical solution of PDEs. 4. PDE stability
analysis. 5. Dissipation and dispersion. 6. High resolution schemes.
7. Meshless methods. 8. Conservation laws. 9. Case study: analysis
of golf ball flight. 10. Case study: Taylor-Sedov blast wave.
11. Case study: the carbon cycle.

Subject: Numerical Linear Algebra and Optimization, UK, Sep 2016

University of Birmingham, UK
7 - 9 September 2016

The IMA and the University of Birmingham are pleased to announce the
Fifth IMA Conference on Numerical Linear Algebra and Optimization. The
meeting is co-sponsored by SIAM, whose members will receive the IMA
members' registration rate.

The success of modern codes for large-scale optimization is heavily
dependent on the use of effective tools of numerical linear
algebra. On the other hand, many problems in numerical linear algebra
lead to linear, nonlinear or semidefinite optimization problems. The
purpose of the conference is to bring together researchers from both
communities and to find and communicate points and topics of common
interest. Conference topics include any subject that could be of
interest to both communities, such as:
Direct and iterative methods for large sparse linear systems;
Eigenvalue computation and optimization; Large-scale nonlinear and
semidefinite programming; Effect of round-off errors, stopping
criteria, embedded iterative procedures; Optimization issues for
matrix polynomials; Fast matrix computations; Compressed/sparse
sensing; PDE-constrained optimization; Distributed computing and
optimization; and Applications and real time optimization

Abstract submission: 30 April 2016
Notification of acceptance of abstracts: 31 May 2016
Conference: 7-9 September 2016

Subject: Postdoc Positions, Applied Industrial Mathematics

The Center for Mathematical Sciences Applied to Industry (CEPID-
CeMEAI) a post-doc position available for starting immediately. The
requirements for each of the positions are described below. The salary
is R$ 6.819,30 (USD 2000,00) per month tax free. The appointed
Post-doc will also get return travel from his/her country to Brazil
paid by the grant. The positions are initially for one year,
renewable for a second year pending on suitable performance.

The main goal of this project is to understand how changes in the
coupling structure of a network can affect the overall function. Using
synchronization as a paradigm of network function, we aim at
understanding how spontaneous collective behavior can be destroyed or
enhanced by such structural modifications. Recent results suggest that
certain modifications can lead to synchronization loss despite the
fact that they enhance topological properties of the network. This
project develops a mathematical theory for this phenomenon, and it is
divided into two objectives of increasing difficulty i) Classification
of structures and links leading to synchronization loss, and ii)
Effects of time-delays in the coupling structure. We will apply our
theoretical results to experiments involving networks of electrical
circuits and time-delayed lasers.

The successful applicant will participate of a collaborative effort
being developed by the Brazilian team headed by Dr. Tiago Pereira and
a British team headed by Prof. Jeroen Lamb. A doctoral degree in
Applied Mathematics, Engineering or a related area is required,
together with strong background on Dynamical Systems in particular
stability theory and synchronization. Candidates with proven skills in
performing independent scientific research and in programming for
high-performance computing environments will be preferred.
