Robert" Subject: Meeting on Inverse problems at Royal Statistical Society Date: Thu, 23 May 2002 Dear All, Please find below an announcement by the Royal Statistical Society that should be of interest to the members of the IPNet. A link to the same announcement is available as http://www.maths.soton.ac.uk/staff/JJForster/RS/ Christian P. Robert Universite Paris Dauphine HALF-DAY MEETING ON INVERSE PROBLEMS CALL FOR PAPERS The Research Section of the Royal Statistical Society is planning a half-day extended ordinary meeting on STATISTICAL APPROACHES TO INVERSE PROBLEMS. The aim is to bring together statisticians and scientists working in this rapidly developing area. In the tradition of RSS Ordinary Meetings, papers presented at the meeting will be published in JRSS, with discussion. The organisers are particularly looking for papers which develop generic statistical methodology applicable to a wide range of problems. Possible topics of interest include, but are not restricted to: deconvolution, inverse Laplace and Fourier problems, estimation of surfaces, wavelet and multiscale approaches, source separation, model choice issues, tomography. The meeting is planned to take place in London in December 2003. Key deadlines are the following: authors who wish to present a paper must submit a single-page abstract by 30 September 2002 authors of selected abstracts will then be invited to submit a full paper of about 10 to 15 journal pages by 28 February 2003 papers will be subject to refereeing, with feedback to authors by 31 May 2003 final versions of accepted papers will be required by 30 September 2003. If you would like to present a paper at this meeting, please send your single-page abstract electronically, as a LaTeX, postscript or PDF file to Christian.Robert@ceremade.dauphine.fr by 30 SEPTEMBER 2002. ----------------------------- From: ross@siam.org Subject: SIAM Conference on Discrete Mathematics (DM02) Date: Thu, 30 May 2002 REGISTRATION NOW The Preregistration deadline for the SIAM Conference on Discrete Mathematics is Friday, July 12, 2002.

Department of Mathematics, UMIST, Department of Mechanical Engineering and Department of Computer Science, University of Sheffield A three year research post is available, funded by the EPSRC, to develop and implement reconstruction algorithms for Tensor Tomography for 3D Photoelasticity. The person appointed will spend the first 18 months in Manchester developing and algorithms to solve the forward problem inverse problems and the remainder of the appointment in Sheffield refining the algorithms, testing them with experimental data and integrating the software developed with the automated measurement system. The successful candidate is likely to hold a PhD in Applied Mathematics or Physics, and is required to have experience of implementing numerical algorithms. Previous experience of Inverse Problems, and computational electromagnetics/optics are highly desirable. An aptitude for working in an experimental setting is preferable since training in this aspect is available. Experience of programming in high level languages on Unix/Linux systems, and in MATLAB are desirable. For enquires please email Dr W. Lionheart on bill.lionheart@umist.ac.uk. Applications, by CV with the names and contact details of three referees, should be sent to Gwyn Cabral, Department of Mathematics, UMIST, PO Box 88, Manchester, M60 1QD UK, Fax +44-161-200 ----------------------------- From: "Haar Romenij, B.M. ter" Subject: Postdoc and PhD position in Eindhoven Date: Sat, 25 May 2002 Eindhoven University of Technology (TU/e), Department of Biomedical Engineering (BME), has a vacancy for: 1 postdoc (2 years) and 1 PhD student (4 years). Starting Date: August 1, 2002 Subject: "Bio-inspired Multiscale Image Representation" The Department of Biomedical Engineering is an inter-university department in which departments of TU/e and University of Maastricht closely collaborate. Education and research focus on the human body and its functioning. BME has biological, medical and technological aspects, making it strongly multidisciplinary. Project: In August 2002 a collaborative program will start between 4 European partners. Goal is to develop new theory and practice in singularity theory, scale-space theory and algorithmics to create efficient algorithms for solving biomedical computer vision tasks. This is a new approach to medical image analysis, inspired by multi-scale models for human visual perception. The overall objective is to summarize images in a generic tree/graph data structure. We will investigate how this representation benefits image coding, storage, shape representations, structural search, matching and indexing, for tasks like image communication, database search, registration of images, computer aided diagnosis, and object recognition. Techniques used are: singularity theory, algorithmics, and scale-space theory. Profile: The candidate postdoc has an academic and a PhD degree in a relevant field and is familiar with multi-scale methods. The candidate PhD student has an academic degree in a relevant field and affinity with mathematical and statistical methods. The candidates like working in a multidisciplinary environment with physicists, mathematicians, biomedical engineers and biologists. Terms of employment: Postdoc resp. PhD student: Fulltime, 2 years, resp. 4 years with intermediate evaluation after 1 year. Salary will be in accordance with national university regulations ("CAO Nederlandse Universiteiten") for postdocs resp. PhD students. Support with personal development and career planning. Attractive secondary labor conditions (among others: a compensation of 1818 euro for the production of the PhD thesis). Contact: Send your letter of application and CV to TU/e, Dept. of BME, to Dr. A. A. Klumper (a.a.klumper@tue.nl), Managing Director, PO Box 513, 5600 MB Eindhoven, mentioning vacancy-number 50.028 (Postdoc) or 50.033 (PhD student). For project information contact dr. L.
