Tensorlab v2.0 brings support for sparse and incomplete tensors and allows you to define your own (coupled) tensor decompositions with structured factors. Users can choose from a library of predefined tensor decompositions and factor structures such as nonnegativity, orthogonality, matrix inverse, Toeplitz, Hankel and Vandermonde structure. A diverse selection of example applications are demonstrated in the tech. report at http://bit.ly/1iKJprY . URL: http://www.tensorlab.net The toolbox is free to use for non-commercial research. We hope that you'll find it useful in your research and we welcome all suggestions and feedback.

Solving partial differential equations (PDE) is a complex topic and requires good coding skills or deep knowledge of appropriate programs. The goal of the Diffpack Smart Environment (DiffpackSE) is to provide a powerful easy to handle interface solving different kinds of PDEs. Just open your bowser (Mozilla Firefox is recommended) and get all instruments online on one page. No installations are required. The interface supports all parts of the simulation process from mesh generation up to graphical 3D results visualization. Choose your equation, create a 2D or 3D mesh, set user defined parameters and get the FEM solution in a fully interactive 3D view. The automatic source code generation enables fast and easy code development in your own Diffpack environment. This gives you the best starting point to develop extensive applications for the solution of more advanced / user defined PDEs employing the powerful Diffpack C++ libraries. The results of the web interface can be embedded in any well-known simulation package and incorporated in your own simulation workflow. Just open DiffpackSE at http://www.inutech.de/DiffpackSE/ and find a new world of mathematical simulation. ------------------------------------------------------- From: Dugald Duncan [log in to unmask] Date: February 07, 2014 Subject: Celebrating 400 years of Napier's logarithms, UK, Apr 2014 Various organisations in Scotland coordinated by the Royal Society of Edinburgh are holding a series of workshops and events to celebrate the discovery/development of logarithms by John Napier in Edinburgh in 1614. The last such celebration was in 1914. * Napier 400 - Numerical Algorithms and Intelligent Software Symposium, 2nd April 2014 at ICMS in Edinburgh The aim of this NAIS one-day scientific symposium is to have presentations by and discussions with international experts on a broad range of topics of current interest in numerical analysis and scientific computing, that might also be interpreted as continuing the spirit of Napier's work of devising efficient algorithms and associated computing devices. However, the meeting will mainly focus on what is happening now and into the future, rather than looking backwards to Napier's time.

As the most versatile medium for transmitting signals and power, fluid (gas or liquid) have wide usage in industry. Fluid systems are used in machine tool applications, vehicle control systems, where high power to weight ratio, accuracy and quick response are required. Fluid systems for industrial processes often involve networks consisting of tanks, pipes, orifices, valves, pumps and other flow devices. It is important to develop a systematic method to mathematically model different types of fluid systems for safe and optimal operations. Conference topics include the following and are invited to be presented in oral and poster sessions: Analysis and computational methods of fluid systems; Computational fluid dynamics (CFD) approach to engineering systems; Fluid power systems; Multiphase flow; Modelling and design of fluid system components; Control design methodologies and techniques for fluid systems and applications; Novel fluid system configurations; New approaches to system modelling and system design; Pressure surge; Hydraulic systems; Medical applications Papers will be accepted for the conference based on a 250 word abstract.

The project involves algorithms, theory, applications and software. The new algorithms will be analyzed and developed with tools from numerical linear algebra and complex analysis, in particular Krylov methods and the theory for analytic functions. The algorithms will be used to study specific problems in acoustics, in particular models of waveguides, and also problems in quantum mechanics and quantum chemistry.

The positions are affiliated with the project High-Definition Tomography (HD-Tomo, www.imm.dtu.dk/~pcha/HDtomo) financed by the European Research Council. Project 1: Prior-Driven Diffusion Regularization for Inverse Problems. We consider a special type of regularization based on (often nonlinear and anisotropic) diffusion, in which the diffusivity is designed using prior information. Such methods are well-understood in image analysis in the context of denoising, but for solving general inverse problems in tomography little is known. The results from image analysis will serve as the starting point for the project, and we will both seek to advance the theory in the field and develop algorithms for a computational approach to the problem. For more details, see www.dtu.dk/job/job?id=76e0ea51-7993-4c48- a2bd-0862cb13c2e9 Project Description 2: Segmentation-Driven Tomographic Reconstruction. We consider tomographic reconstruction aimed at subsequent segmentation. Based on certain applications such as porous materials analysis, we will incorporate many kinds of prior information in order to produce more suitable reconstructions for the segmentation. One obvious advantage is that with the help of “better” reconstruction results the segmentation can be simplified and become more robust to the parameter selection, e.g., a simple thresholding technique may suffice. Concerning prior information in porous material, we will design new mathematical models and numerical algorithms to obtain new kinds of tomographic reconstruction, which can benefit the segmentation. For more details, see www.dtu.dk/job/job?id=308ccaea-44d8-46a3- 88e8-e52cb5a1d07f Candidates for both positions must have a master degree in applied mathematics, or equivalent academic qualifications, and must have a strong background in applied mathematics and numerical computations.
