Moreover, the groups of theoretical, computational and experimental researchers need to interact and share some appropriate tools that rigorously bridge the gap between the information stemming from measurements and that corresponding to theoretical predictions. Hence, IPDO Symposium is a privileged place for scientific exchanges relating the measurement and theory approaches through the use of suitable optimization algorithms, and is expected to provide an excellent basis for cross-fertilization of ideas so that more general, robust, accurate and computationally economical design methods are created for multi-disciplinary applications. Successful previous versions of the IPDO Symposium were held in Rio de Janeiro, Brazil (2004), Miami Beach, USA (2007) and Joao Pessoa, Brazil (2010). Areas of interest Contributions dealing with theoretical concepts in inverse techniques, optimization and design theory are expected. Methods that are applicable to multiple disciplines for practical applications are encouraged, such as energy storage, biomass valorization, solar energy conversion, material functionalization, material processing, remote sensing, non-­destructive evaluation, material properties determination, nano and micro technologies, petrochemistry, aeronautics, astronautics, biomedicine, transport and sensing of pollutants, imaging, geoprospecting, financial analysis, etc. Abstracts and papers submission Please submit a two-page abstract in pdf format via the symposium website at http://ipdo2013.congres-scientifique.com. The templates can be found at the symposium website. All accepted abstracts will be in a Book of Abstracts provided to all participants during IPDO-2013. Final papers passing a three-person review process will be provided electronically to all those that register by May 15, 2013. Selected papers will be published in the Inverse Problems in Science and Engineering journal after an additional review.

This is a joint project of the Ernst Ruska-Centre for Microscopy and Spectroscopy with Electrons (ER-C) and the Institute of Energy and Climate Research - Stratosphere (IEK-7). Background The aim of the project is to measure the three-dimensional distribution of magnetization inside an individual nanometre-sized magnetic crystal from a series of images acquired using the technique of electron holography. Nanoscale magnetic materials are of immense importance in scientific and technological disciplines. The project promises to provide a powerful new analytical tool at the frontiers of the highest spatial resolution analysis of spin and electronic structures that will have farreaching impact beyond a specific research domain. Tasks The student will develop a novel model-based inversion algorithm, which will be used to find the best-fitting distribution of magnetic moments in a specimen that is consistent with a series of experimental phase images acquired using electron holography. As this is an ill-posed problem, the sensitivity of the solution to errors in the data, the uniqueness of the result and the use of prior information will need to be addressed. The algorithm will be applied to experimental measurements acquired using a state-of-the-art transmission electron microscope available in the ER-C, beginning with simpler two-dimensional problems. The ultimate aim will be to provide quantitative measurements of three-dimensional internal magnetic fields in nanoparticles. Requirements Suitable candidates should have a university degree and a strong background in computional mathematics or physics.

The areas of interest to the group include computational wave propagation, optimization, inverse problems, applied harmonic analysis, sparsity (compressive sensing), linear algebra, fast algorithms, radar imaging, seismic imaging. All the details are at http://math.mit.edu/icg/openings/ ----------------------------- Subject: Postdoctoral Research Position in Computational Imaging at Tufts University From: Misha Kilmer Date: 10/8/2012 Postdoctoral Research Position in Computational Imaging at Tufts University A postdoctoral researcher, possible immediate start date, is sought in the area of computational imaging to support the following project. Advanced Image Formation For Diffuse Optical Tomography (DOT): As part of a larger program in the area of breast cancer detection using optical tomography, the objective of this project is the development and deployment of image formation methods for the imaging of breast cancers from hyperspectral DOT data sets (i.e., data collected from over 100 narrowly spaced wavelengths in the near infrared). Geometric inversion techniques based on recently developed level set ideas are to form the basis for the inversion methods. The forward problem will require efficient solution of multiple large-scale discretized PDEs. In addition to large-scale algorithm development, a primary objective is the processing and analysis of clinical data being developed under a separate portion of the overall project. Initial funding for one year, with the possibility of annual renewal, subject to performance review, for up to 3 years. A PhD and relevant expertise in one or more of the following is expected: computational inverse problems, applied mathematics or scientific computing with experience in computational PDEs, numerical linear algebra, and/or optimization. Previous interdisciplinary project experience a plus. If interested, please send CV and cover letter to Prof. Eric Miller (elmiller@ece.tufts.edu) and Prof. Misha Kilmer (misha.kilmer@tufts.edu). Tufts University is an Affirmative Action/Equal Opportunity employer. We are committed to increasing the diversity of our faculty. Members of underrepresented groups are strongly encouraged to apply. ----------------------------- Subject: 3 Postdoctoral positions at the Seismic Laboratory for Imaging and Modelling From: Felix Herrmann Date: 11/1/2012 Dear colleagues, We have three open postdoctoral positions at the Seismic Laboratory for Imaging and Modelling in the following areas: * computational and theoretical seismology: seismic modelling, wave-equation based imaging and inversion * observational seismology: development of practical data acquisition scenarios and workflows for full-waveform inversion * compressive sensing: design and implementation of novel acquisition, sparse/low-rank recovery algorithms, and directional transforms including curvelets * scientific computing & inverse problems: PDE-constrained optimization and direct and indirect solvers for the Helmholtz equation, and * optimization & machine learning: large-scale convex and stochastic optimization, etc. For more information please follow https://www.slim.eos.ubc.ca/node/50662 or to our add at mathjobs (Position ID: UBC-SLIMPDF [#4250]) https://www.mathjobs.org/jobs/UBC/4250 where the candidates can submit their applications.

Mueller and Samuli Siltanen 2012 / xiv + 351 pages / Softcover / ISBN 978-1-611972-33-7 / List Price $84.00 / SIAM Member Price $58.80 / Order Code CS10 This book explains how to identify ill-posed inverse problems arising in practice and how to design computational solution methods for them; explains computational approaches in a hands-on fashion, with related codes available on a website; and serves as a convenient entry point to practical inversion. The guiding linear inversion examples are the problem of image deblurring, x-ray tomography, and backward parabolic problems, including heat transfer, and electrical impedance tomography is used as the guiding nonlinear inversion example. The book's nonlinear material combines the analytic-geometric research tradition and the regularization-based school of thought in a fruitful manner, paving the way to new theorems and algorithms for nonlinear inverse problems. Furthermore, it is the only mathematical textbook with a thorough treatment of electrical impedance tomography, and these sections are suitable for beginning and experienced researchers in mathematics and engineering.
