It provides a modern theory of observability based on a new paradigm borrowed from theoretical physics and the mathematical foundation of that paradigm. In the case of observability, this framework takes into account the group of invariance that is inherent to the concept of observability, allowing the reader to reach an intuitive derivation of significant results in the literature of control theory. 2020 / xiv + 262 pages / Softcover / 978-1-611976-24-3 / DC37 List Price: $84.00 SIAM Member Price: $58.80 Link to the book: https://bookstore.siam.org/dc37 Browse more SIAM books by visiting: https://bookstore.siam.org<https://bookstore.siam.org/> ------------------------------------------------------- From: Communications in NLA [log in to unmask]<mailto:[log in to unmask]> Date: August 30, 2020 Subject: Communications in NLA, ONLINE, Mondays The online seminar series "Communications in NLA" will soon start and take place every Monday at 15:00 CEST, starting from September 7, 2020.

This first workshop will provide an overview of both state-of-the-art and open challenges drawing from multiple themes (theory, analysis of the equations, computation, and data analysis) within the broad context of Einstein's general relativity theory. Many of the talks will focus on the computation of gravitational radiation from compact bodies using numerical and analytical approaches. Speakers will draw from physics, astronomy, and applied and pure mathematics. The workshop will feature computational tutorials on gravitational waveform catalogs, software for numerically solving the Einstein and the relativistic magneto-hydrodynamic equations, Black Hole Perturbation Toolkit, and symbolic tensor computations with xAct. Due to COVID-19, this workshop will be held online. Please apply using the link "Apply with Cube" at the workshop website (https://icerm.brown.edu/programs/sp-f20/w1/) if you would like to participate in this workshop. ------------------------------------------------------- From: Steffen Boerm [log in to unmask]<mailto:[log in to unmask]> Date: August 24, 2020 Subject: Simulation and High-Performance Computing, ONLINE, Sep 2020 We are happy to announce a two-week course "Simulation and High-Performance Computing" aimed at M.Sc. and Ph.D. students in Engineering, Physics, Chemistry, and Biology. The first week of the course provides an introduction to basic numerical techniques required in computer simulations, e.g., time-stepping methods, finite-difference discretization, and corresponding solvers. This part assumes that participants are familiar with analysis and linear algebra. The second week focuses on the implementation of these techniques on modern computers, taking advantage of vectorization, parallelization, GPU computing, and distributed computing. This part assumes that participants are familiar with the C programming language. Due to the current COVID-19 crisis, the course will be held online, with lectures provided as pre-recorded videos combined with discussion groups and interactive programming exercises.

Electron beam melting (EBM) is a powder bed fusion technology for additive manufacturing in metal, where fine metal powder is melted, layer by layer, with a strong electron beam in a vacuum chamber. This special technique can be used to produce arbitrarily shaped parts in special alloys with low residual stresses. This project is about the topology optimization of structural mechanic properties applied to EBM for industrial applications using finite element methods for the structural mechanic's computations. As important as the numerical and the optimization techniques, is the mathematical modelling of the material properties relevant to the applications and how to include these into the optimization problem. The project is part of an international collaboration with academic and industrial partners in both Brazil and Sweden. The candidate will need to have expertise in structural mechanics, a good working knowledge of optimization, mathematical modelling and also in programming and scientific computing. The candidate will be based in Sao Carlos, Brazil, and will be required to spend some time in Sweden with collaborators there. The post is initially for one year and can be renewed for another two depending on performance. To apply, please send a CV and a reference letter to [log in to unmask]<mailto:[log in to unmask]> .
