Rose, Professor of Computer Science at Duke University, passed away on June 12, 2015, from sepsis which arose from a staph infection. Don received his BA from Berkeley in 1966 and his MA and PhD from Harvard in 1967 and 1970. He then held positions as an Instructor of Applied Mathematics at Harvard during Spring Semester 1970, as an Assistant Professor of Mathematics at the University of Denver from 1970 to 1972, as an Assistant Professor and then Associate Professor of Applied Mathematics at Harvard from 1972 to 1977, as a Professor of Computer Science and Mathematics and as Chairman of Computer Science at Vanderbilt from 1977 to 1978, as a Researcher at Bell Labs from 1978 to 1984, and lastly as a Professor of Computer Science and Mathematics at Duke from 1991, as well as the Chairman of Computer Science from 1984 to 1991. Don's research was on numerical linear algebra, sparse matrix computations, scientific computing, and more recently on the numerical solution of nonlinear algebraic and differential equations. When I was a grad student at Berkeley, I taught the course in ALGOL programming in 1964-65; it was the lab connected to the undergrad numerical analysis course, Math 128A. Don was a student in my class, and he constantly had his hand raised asking questions. Later, Don and I co-authored 4 publications on sparse matrices during 1971-76. I am stunned by Don's passing and will greatly miss him. James R.

Walker 2015 / x + 152 pages / Softcover / ISBN 978-1-611973-95-2 / List Price $74.00 / SIAM Member Price $51.80 / Order Code DC28 This self-contained overview of differential geometry explains how to differentiate a function (in the calculus sense) with respect to a “shape variable.” This approach, which is useful for understanding mathematical models containing geometric partial differential equations (PDEs), allows readers to obtain formulas for geometric quantities (such as curvature) that are clearer than those usually offered in differential geometry texts. Readers will learn how to compute sensitivities with respect to geometry by developing basic calculus tools on surfaces and combining them with the calculus of variations. Several applications that utilize shape derivatives and many illustrations that help build intuition are included.

The successful candidate(s) will join NLAFET, which is one of the high-profile extreme-scale computing projects funded by the European Commission within the recent FET-HPC call under Horizon 2020. NLAFET is coordinated by Umea University with international partners from INRIA (France), University of Manchester and STFC-RAL (UK). Future extreme-scale supercomputers will be heterogeneous and lead to new and challenging demands for efficient numerical algorithms and parallel software libraries. The aim of NLAFET is to tackle these challenges and ultimately deliver new scalable numerical libraries for fundamental problems in numerical linear algebra, including the solution of dense and sparse systems of equations and eigenvalue problems. Achieving this requires a co-design effort including developing novel algorithms, exploration of advanced scheduling strategies and runtime systems, offline and online autotuning, as well as avoiding communication and synchronization bottlenecks. The positions will focus on design, implementation, and evaluation of parallel algorithms for matrix eigenvalue problems with regards to the extreme-scale challenges. The research will be done in close collaboration with recognized researchers and PhD students in the research group as well as with other partners in NLAFET.

Dynamical systems are often subject to physical parameters with an important level of uncertainty. Application engineers then want to know how sensitive the system is with respect to these parameters, for example, how much a parameter may change without losing stability or a performance level. This leads us to eigenvalue problems with uncertainty. The question how the performance or robustness of the system can be optimized by a careful choice of design parameters or by active or passive control, leads us to eigenvalue optimization problems. Recently, significant advances have been obtained on robust control design approaches, grounded in eigenvalue optimization, as well as on solving nonlinear eigenvalue problems, arising in the analysis of classes of large-scale systems. The aim of the PhD project is to shift the state-of-the-art from control of stand-alone systems to large networks of interconnected systems. The goal is to compute simple controllers, which are easy to implement, and possibly decentralized, i.e., where a global objective is reached by local actions. The project will be realized by combining advances in numerical linear algebra, control theory, numerical optimization, and approximation theory. The methods and algorithms are validated on problems from mechanical and electrical engineering (traffic flow control, communication networks,…).

The successful candidate will be a part of the UCL Centre for Medical Image Computing, the UCL Centre for Inverse Problems, and the department of Computer Science researching new instrumentation and algorithms for dynamic imaging. The foot and ankle are complex structures comprising 28 bones and the structure reflects the complexity of activity for movement, shock absorption stability and balance. Successful diagnosis and treatment planning can be extremely difficult due to limitations posed by existing imaging modalities. Understanding the complex 3D motion of the foot and ankle joints is vital in assessing the progression of long term diseases such as arthritis and devising new treatments for both injury and disease of the ankle and foot. A new low dose vertical axis cone beam CT scanner, pedCAT, has been developed by CurveBeam, which unique feature is the ability to provide 3D images of the weight bearing foot and ankle with the patient standing motionless in a natural standing position. The aim of the PhD project is to develop and implement imaging protocols and reconstruction algorithms for imaging of dynamic function under load with the pedCAT scanner. To this end, the candidate will mathematically formulate the associated dynamic inverse problem (DIP) and investigate under which conditions and with what additional information the DIP can be uniquely and stably solved. The candidate will devise data acquisition protocols and image reconstruction algorithms for the proposed scenarios.

The studentship is due to start on the 28th September 2015, or as soon as possible thereafter. ------------------------------------------------------- From: Claude Brezinski [log in to unmask] Date: June 29, 2015 Subject: Contents, Numerical Algorithms, 69 (3) Numerical Algorithms, Vol. 69, Issue 3 A block MINRES algorithm based on the band Lanczos method, Kirk M.
