Subject: Don Rose

Donald J. Rose, Professor of Computer Science at Duke University,
passed away on June 12, 2015, from sepsis which arose from a staph

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.

Subject: New Book, The Shapes of Things

Announcing the June 25, 2015, publication by SIAM of:
The Shapes of Things: A Practical Guide to Differential Geometry and
the Shape Derivative, by Shawn W. Walker

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.

Subject: Postdoc/PhD Positions, Parallel Computing, Extreme-Scale Systems

Department of Computing Science at Umea University, Sweden invites
excellent candidates to apply for postdoctoral and PhD positions. 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.

PhD position "Computational methods for robust control of large-scale
interconnected systems"

The dynamic behavior of a linear time-invariant system is determined
by the solutions of an eigenvalue problem. 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

Keywords: numerical linear algebra, dynamical systems, control and
optimization, uncertainty quantification

Subject: PhD Position, Univ College London (UCL)

Applications are invited for PhD studentship to work with Dr Marta
Betcke (CMIC, CIP, CS), Dr Andrew Goldberg (IoO, RNOH), Prof David
Hawkes (CMIC, CS, MedPhys) and Guy Long (CurveBeam Europe Ltd) on
X-ray CT imaging of dynamics of weight bearing foot and ankle. 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.

Further details are available at!/?project=137 If you are interested in
applying please contact Dr Marta Betcke First
round of applications will close on 16th August 2015. The studentship
is due to start on the 28th September 2015, or as soon as possible
