De los Reyes Centro de Modelización Matemática (MODEMAT), Escuela Politécnica Nacional Quito, Springer Verlag, February 2015, 123 pages, ISBN 978-3-319-13395-9. This book introduces, in an accessible way, the basic elements of Numerical PDE- Constrained Optimization, from the derivation of optimality conditions to the design of solution algorithms. Numerical optimization methods in function-spaces and their application to PDE-constrained problems are carefully presented. The developed results are illustrated with several examples, including linear and nonlinear ones. MATLAB codes, for representative problems, are included. Furthermore, recent results in the emerging field of nonsmooth numerical PDE constrained optimization are also covered. The book provides an overview on the derivation of optimality conditions and on some solution algorithms for problems involving bound constraints, state-constraints, sparsity enhancing cost functionals and variational inequality constraints.

The systems including their initial configuration and a dedicated development set have been released. Participants in the task are expected to find the best setting of model weights, possibly adding sparse features as available in the underlying MT system, Moses Release 3.0. Without sparse features, there are 9 real-valued weights to set. In the task, you are most welcome to experiment with: - various optimizers - various MT evaluation metrics - various sparse features - additional development data (non-constraint track) or any other changes in the tuning process. Any source-code change is permitted for the tuning phase. If you wish to make use of our complimentary manual evaluation for translations into Czech during your development, please register by February 22, 2015. Otherwise, no registration for the task is needed, just follow the instructions on the task web page: http://www.statmt.org/wmt15/tuning-task/ ------------------------------------------------------- From: Gianluigi Rozza [log in to unmask] Date: February 14, 2015 Subject: Model Reduction of Parametrized Systems, Italy, Oct 2015 The third edition of MoRePaS, Model Reduction of Parametrized Systems, will be held at SISSA, International School for Advanced Studies, Trieste, Italy on October 13-16, 2015.

We propose a PhD offer in numerical/experimental fluid mechanics/ two dimensional turbulence. Deadline: 20th of february 2015 Keywords: fluid mechanics, two dimensional turbulence, numerical simulations. The topic of the present PhD offer is thermal convection on the surface of a sphere with direct applications to recent experiments. In these experiments, thermal convection is produced on the surface of a half soap bubble, heated at its equator and whose thickness is small enough for the flow to be confined in two dimensions (the surface of the bubble). Other phenomena can be obtained: large isolated vortices whose properties as well as their intensity can be measured under different conditions. The reasons for the emergence and persistence of these isolated vortices are still lacking. Further, the motion and intensification of these vortices have been positively compared to the dynamics of hurricanes and cyclones on Earth so a full understanding of the dynamics of these vortices may be important for understanding particular features of atmospheric flows for example. Also, rotation of the bubble plays an important role in the behavior of the vortices and introduces non trivial effects on the statistics of the thermal convection. Here we will employ numerical simulations to shed light on this problem. The fluid behavior is described using the Navier Stokes equations for the two-dimensional thermal convection under the Boussinesq approximation. Stereographic projection based numerical simulations of such a situation will help bring forth detailed information about such objects (the vortices) as well as the statistics of the thermal convection on the surface of the bubble, with and without rotation. The prospected PhD student will work on the analysis of the numerical simulations as well as the experimental data in order to make comparisons between experiments and simulations and make progress in our understanding of the physics of this experimental setup and its possible implications and applications. Competences: strong background in mathematics, fluid mechanics, numerical analysis, Fortran, Matlab, parallel computing. Some knowledge in two-dimensional turbulence will be highly appreciated. Students interested in this offer have to contact as soon as possible Patrick Fischer, +33 540 002 130, [log in to unmask] to get the application material. ------------------------------------------------------- From: Oliver Junge [log in to unmask] Date: February 12, 2015 Subject: PhD Position, Numerics, Simulation, TUM/Siemens CT, Munich, Germany Applications are invited for a PhD student position at the Chair for Scientific Computing, TU Muenchen and Siemens Corporate Technology, Germany. In the PhD thesis, hybrid models for complex engineering systems shall be developed where some components are described by physical and others by black box models. The model shall be consistent with the data which will continuously be collected from sensors and inspections on the real system. To this end, the calibration of the model to the (noisy) data will be done by Bayesian inference. The resulting model shall be sufficiently small in order to enable a real time simulation under uncertainty in the systems parameters and initial conditions. In particular, confidence intervals on future system states shall be computed. Prerequisites include a strong background in modeling and numerics (as evidenced, e.g., by a master's degree in Mathematics or related fields), very good analytical and programming skills, high motivation for doing independent research and a creative mind. Prior knowledge on general model order reduction strategies (e.g. Kahunen- Loewe expansions), bifurcations and stochastics is welcome. The salary level is according to the German public service regulation (TV-L 13) at 50% full-time-equivalent. Applications with the usual documents (letter of motivation, curriculum vitae, certificates, two letters of recommendation) should be sent electronically as a single PDF file to Prof. Dr. O. Junge ([log in to unmask]) by March 15, 2015. ------------------------------------------------------- From: Len Bos [log in to unmask] Date: February 13, 2015 Subject: Call for Papers, Special Issue, Multivariate Approximation We are announcing a special issue of the journal Dolomites Research Notes on Approximation, DRNA http://journals.padovauniversitypress.it/dolomites/ published by the Padova University Press, entitled: "Ten years of the Padua Points: the state of the art in multivariate polynomial interpolation and approximation".
