McGahan, Rome Lab. Imaging methods are increasingly being applied to a wide range of applications including clinical medicine, geophysics, remote sensing, and materials testing. Practical systems invariably must consider nonidealities that corrupt the quality of data, limit the range of measurements and computational effort, and restrict the type of experimental strategies that can be considered. Energy sources used in imaging studies include magnetic, acoustic, electrical and a wide range of electromagnetic sources. These may be located external to the medium or inside. Detection modes may or may not be time dependent and can range from backscatter only to full tomographic measurement schemes. Whereas the types of physical measurements performed can vary, the numerical methods and computational strategies used to evaluate the data are often similar. A common feature complicating many of these methods is the uncertainty regarding the volume of medium probed by the penetrating or emitted energy. Frequently this uncertainty is due to the effects of scattering. Accurate knowledge of the energy distribution requires information about the properties of the medium, which is the unknown being examined. As a result useful methods frequently must consider approximate solutions that represent compromises between computational effort, physical accuracy of the modeling scheme, and quality and type of available data. Imaging methods used in clinical medicine currently provide physiological information about in-vivo ion and metabolite levels, enzyme activity, hormone receptors, oxygen-deficient states, sensory-invoked potential, dynamics of vascular flow and other parameters. Methods which provide this information include: magnetic resonance imaging (MRI), positron emission tomography (PET), single photon emission computed tomography (SPECT), optical and microwave tomographic imaging methods, electrical impedance tomography (EIT), EEG and magnetic source imaging methods, among others. Acoustic, impedance, and electromagnetic source imaging methods are also widely applied to probe a range of materials and media to search for foreign objects, carbon fuels, subsurface faults, and other applications in nondestructive testing and remote sensing. Principal topics of interest will fall into four main areas: I) mathematical aspects of inverse methods (e.g., methods for dealing with ill-conditioning, limited noisy data, missing phase information, superresolution etc.); ii) computational strategies; iii) modeling methods for forward and inverse scattering phenomena; and iv) interdisciplinary applications including clinical medicine, optics, astronomy, geophysics, remote sensing, etc. This conference will bring together leading experts from universities, medical centers, government laboratories, and industry to discuss the latest developments in the diverse and fast developing field. Topics will include, but are not limited to, the following areas: Imaging modalities: (MRI, PET, SPECT, EIT, optical, microwave, EEG/magnetic source, and acoustic imaging methods) * quantitative methods for imaging strong scatterers * inverse scattering problems * oxygen deficient states * monitoring of organ function (hepatic, cerebral, cardiac, renal, skeletal muscle, breast) * metabolite levels * tumor detection * laboratory modeling studies * time-resolved, harmonic, and time-independent illumination schemes * novel detection methods * multiwavelength analysis. Methods for solving ill-posed problems * explicit methods * iterative perturbation methods * derivation of homogeneous and inhomogeneous reference states * use of a priori information * projection methods * regularization techniques * application of neural net methods * layer stripping. Efficient numerical methods * FDTD * finite element * Monte Carlo * discrete ordinate * multigrid methods * hybrid methods to model complex media. Computational strategies * parallel methods * novel problem solving environments.

ENGL" Subject: digest submission Date: Tue, 26 Nov 1996 Two Positions at MathConsult GmbH At MathConsult GmbH in Linz, Austria, two positions are vacant. MathConsult GmbH is a startup company which was founded as a bridge institution between the Industrial Mathematics Institute (Prof. Engl) at the University of Linz and industry. It should help to speed up the transfer of mathematical expertise from university to industry and economy and provide solutions to industrial problems, including software. In general, there is a close cooperation between MathConsult GmbH and the Industrial Mathematics Institute. We are looking for mathematicians/ software engineers for the following two projects: The first project deals with a new technology for obtaining metallic iron from iron ore. There will be a project team with one person from the Industrial Mathematics Institute and one person from MathConsult GmbH working full time on the project and some people from our industrial partner working part time on the project. The project team should develop a mathematical model for the process and then develop codes for the numerical simulation of the process (in C++). Applicants should have a degree in Applied Mathematics, a sound knowledge of numerics of PDEs and experience in C++ programming. The second project deals with the mathematics of financial markets. Our partner company provides programs for portfolio management and risk analysis.
