Subject: Travel-awards, Preconditioning 2017, Canada, Jul-Aug 2017


Preconditioning 2017 conference in Vancouver, Canada
http://www.cs.ubc.ca/~greif/precon17/

As the deadline for submitting an abstract/paper to the
preconditioning-2017 conference is fast approaching (May 31st) we are
happy to inform participants that funding (NSF) is now available to
support travel of junior U.S. participants to the meeting.
Restrictions apply and they are as follows: You must be US permanent
resident or citizen, and a junior researcher (defined as someone who
received the PhD less than 6 years before the conference) and you must
have no current funding from NSF. To apply please send a cover letter
to saad@umn.edu which certifies that you are eligible to receive an
award according to the rules stated above. Include a recent CV, the
name of someone we can contact for a recommendation letter, and, if
you are presenting a paper or poster, the title and abstract of your
presentation.

Subject: Sparse Days at CERFACS, France, Sep 2017


The annual Sparse Days meeting will be held at CERFACS in Toulouse on
7th and 8th September 2017 although (see below) it might be extended
to start on 6th September.

Registration is free but we ask people who are coming to register now
so we can judge numbers to see whether the extra day is needed and how
large a lecture room we will need. The reason for this is that much
preliminary interest has been shown because the meeting will inter
alia celebrate a significant birthday of Professor Iain Duff, who was
Project Leader of the Parallel Algorithms Team from its inception in
1987 until 2010 and is still a consultant to the Team.

You should register before July 16th by completing the online form:
http://cerfacs.fr/en/sparse-days-2017-at-cerfacs/ (English), or
http://cerfacs.fr/colloque-sparse-days-2017-cerfacs/ (French)
indicating whether you want to give a talk. We will not have any
parallel sessions hence the need to know this when planning the
schedule. Although an emphasis will be on parallel aspects, any talk
that has an association with sparsity is welcome. The length for a
talk plus questions is 30 minutes.

Information on accommodation can be found on the web page and a
limited amount of free on site accommodation should be available for
students. Students wanting to apply for this accommodation should
contact Brigitte Yzel on yzel@cerfacs.fr.

A celebratory conference dinner will be held on Thursday September 7th
that will hopefully be heavily subsidised, especially for students.

Subject: Cryptography and Coding, UK, Dec 2017


12 - 14 December 2017, St Catherine's College, University of Oxford

The mathematical theory and practice of cryptography and coding
underpins the provision of effective security and reliability for data
communication, processing and storage. Theoretical and practical
advances in the fields of cryptography and coding are therefore a key
factor in facilitating the growth of data communications and data
networks of various types. Thus, this sixteenth International
Conference in an established and successful IMA series on the theme of
"Cryptography and Coding" is both timely and relevant. Original
research papers on all technical aspects of cryptography and coding
are solicited for submission. It is anticipated that the proceedings
will be published in Springer's Lecture Notes in Computer Science
series, and will be available at the conference.

Submission Deadline: 14 July 2017
Author Notification: 5 September 2017
Proceedings Version Deadline: 22 September 2017

Submissions must not substantially duplicate work that any of the

authors has published elsewhere or has submitted in parallel to a
journal or any other conference or workshop with proceedings.
Accepted submissions may not appear in any other conference or
workshop that has proceedings. Authors of accepted papers must
guarantee that their paper will be presented at the conference and
must make a full version of their paper available online.

Submissions should be submitted via EasyChair:

From: Ken McKinnon k.mckinnon@ed.ac.uk
Date: May 19, 2017
Subject: Postdoc Position, Multi-scale optimization of energy systems, Edinburgh


Applications are invited for the post of PDRA in the multi-scale
optimization of energy systems. The post is available for an immediate
start for 36 months. The precise start date is flexible.

The post holder will join the Centre for Energy Systems Integration
(CESI), a new 20M GBP EPSRC consortium project involving Newcastle,
Edinburgh, Durham, Heriot-Watt and Sussex Universities. The aim of
this project is to understand the complex relationship between energy
supply, demand and infrastructure and how this will evolve.

Within CESI, Edinburgh is responsible for developing modular
multi-scale stochastic planning and operational models and solution
methods. Operational and planning models operate over different time
scales, and local area energy networks need to operate in an
integrated way in regional, national and international scale models. A
single monolithic model at high time and spatial resolution is
computationally intractable, so our focus will be on developing
decomposition approaches that calibrate and select sub models at the
appropriate spatial and time scales.

The starting salary will be in the range 32,004 - 38,183 GBP,
depending on experience. The closing date for receipt of applications,
including reference letters, is 12th June 2017.

For further particulars and how to apply see

p_id=039891

Informal enquiries are encouraged; please contact Professor Ken
McKinnon initially by e-mail: k.mckinnon@ed.ac.uk.

Subject: Postdoc Position, NA, Alexander Grothendieck Institute, Montpellier


The Alexander Grothendieck Institute in Montpellier (IMAG,
http://imag.edu.umontpellier.fr) has an opening for a postdoctoral
researcher in Numerical Analysis. The goal is to extend the recently
developed Hybrid High-Order technology [1,2] to advanced problems in
fluid or solid mechanics.

The successful candidate has a Ph.D. in Applied Mathematics or related
subjects and a strong theoretical background on standard and new
generation discretization methods for PDEs. Implementation and
numerical testing on scientific platforms will also be required.

The starting date of the post-doc is September 2016, and the initial
duration is 12 months. To apply, please send a CV including a full
list of publications along with a motivation letter to Daniele A. Di
Pietro (daniele.di-pietro@umontpellier.fr). This address can also be
used for inquiries.
