Subject: A linear algebra query

Suppose in real n dimensional space you have a list of (column)
vectors q_1, ..., q_n that you know are orthonormal. How do you tell
in O(n^2) time whether it has positive or negative orientation?
Equivalently whether the orthogonal matrix Q that they form has
determinant +1 or -1?

Subject: Design Optimisation, UK, Apr 2018

The Special Interest Group on Numerical Optimisation in Fluids under
the umbrella of the UK Fluids network is organising an introductory
training on

Design optimisation with metamodels and metaheuristics, structural
topology optimisation
Cambridge University, 16-17 April 2018
http://signumopt.sems.qmul.ac.uk/events/

The lectures are presented by Prof Thompson (Leeds), Dr. Querin
(Leeds) and Prof Toropov (QMUL), the meeting his hosted by Prof.
Juniper (CAM).

This is an excellent training course to get your students up and
running with the basics of optimisation, in particular gradient-free
methods as well as structural optimisation with methods such as SIMP.

Registration will close once places are filled, at the latest on 9
April 2018. The cost for attendees is subsidised by the SIG.

The SIG is organising a second training on gradient-based
methods/adjoints in Glasgow preceding the Eccomas conference in June.

1) the characterisation of helical equilibria, including stability
properties, in both the cases of self-avoiding and self-contacting
configurations,

and

2) the equilibria of knots in the presence of friction.

The first project will be carried out in collaboration with the group
of Prof J. Kolinski (emsi.epfl.ch) and the second in collaboration
with the group of Prof Pedro Reis (fleXLab: Flexible Structures
Laboratory)

Preferences will be given to applications at the postdoctoral level,

Subject: PhD Position, Computational Imaging, Univ of Edinburgh

Applications are invited for a postgraduate research position leading
to a PhD degree in Electrical Engineering at the Institute for Digital
Communications within the School of Engineering at the University of
Edinburgh. The position is fully funded for UK and EU applicants, who
have a background in computer science, applied maths or engineering.

Description: Chemical Species Tomography (CST) is a diagnostic
modality for gases and other optically transparent fluids, based on
measurements and models of spectroscopic absorption and laser
attenuation. Although still in its early stages of development, CST is
considered as an effective solution for imaging in-situ the
concentration of chemical species such as pollutants in the exhaust
plumes of gas turbines, aviation engines and power generators. Its
application in the aerospace sector is motivated by the need to
provide combustion diagnostics for jet engines in order to prevent
malfunction and failure. At the same time, CST provides an adjunct
tool for assessing the performance and environmental footprint of
alternative, cleaner aviation fuels. The focus of the project is to
investigate the properties of the inverse problem and develop image
reconstruction algorithms that are better equipped to deal with
fitting model parameters with a relatively few data. Extensions to
this work are also applicable in other application areas such as
spectral X-ray tomography from limited angle acquisitions.

The project will benefit from the collaboration with academics and
researchers within an existing network of collaborators from a number
of UK universities, as well as national and international industrial
partners in the photonics, aviation and fuels sectors.
