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 download. - 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.

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 Further information: http://tinyurl.com/IMANLAO2016 ------------------------------------------------------- From: Marnix Van Daele [log in to unmask] Date: April 25, 2016 Subject: Professor Position, Applied Mathematics, Ghent Univ The Department Applied Mathematics, Computer Science and Statistics at Ghent University (Belgium) invites applications for the position of a full-time professor in the rank of assistant professor (tenure-track) in one of the disciplines artificial intelligence/big data science/mathematical modelling All information about this open position can be found at https://edit.ugent.be/nl/vacatures/zap/voltijds-ambt-van-docent-tenure- track-in-het-vakgebied-artificiele-intelligentie-big-data-science-wiskundige- modellering/ https://edit.ugent.be/en/work/vacancies/professorial-staff/full-time-position- as-professor-in-the-rank-of-assistant-professor-tenure-track-in-the- discipline-of-artificial-intelligence-big-data-science-ma\ thematical-modelling/ Application deadline is May 25 2016 ------------------------------------------------------- From: Etienne Emmrich [log in to unmask] Date: April 22, 2016 Subject: Professorship Position, Numerical Methods for PDEs, Tech Univ Berlin Technische Universität Berlin calls for applications for a professorship (tenured, salary grade W3) in Mathematics, specialization in numerical methods for partial differential equations.

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. ------------------------------------------------------- From: Isabel M.
