Subject: Summer School, Hierarchical Energy Based Modeling, Germany, Aug 2018

The "Summer School on Hierarchical Energy Based Modeling", taking
place on August 27-31, 2018 at the Technische Universitat Berlin,
provides an introduction to energy based modeling with particular
emphasis on port-Hamiltonian systems. The approach allows to deal
with coupled systems from different physical domains that act on
widely different scales. Each physical system is modeled via a model
hierarchy of port-Hamiltonian systems. The systems are coupled via a
network of uni-physics nodes coupled via power conserving
interconnections so that the full system stays port-Hamiltonian. Using
this very flexible approach, it is possible to control the accuracy of
each component separately and to the need of the application. As real
world test cases models from gas transport optimization, power grid
modeling, or acoustic field simulation will be discussed.

The lectures will be given by Volker Mehrmann (TU Berlin).

The Summer School is part of the training activities in the Innovative
Training Network ROMSOC ("Reduced Order Modelling, Simulation and
Optimization of coupled System") funded by the European Union's
Horizon 2020 research and innovation programme.

The registration for the Summer School is free and the school is open
for all interested PhD and Master students.

Subject: Signal Processing & Condition Monitoring, Cuba, Nov 2018

Newer and sophisticated Signal Processing (SP) techniques are
continuously applied on different fields of science and technology.
Condition Monitoring (CM) is an area that receives significant
benefits from the development of Signal Processing techniques. In
order to expose some of the more relevant findings involved on the
application of SP techniques on CM, the First International Symposium
on Signal Processing & Condition Monitoring (ISSPCM), this time as
Special Session at the International Conference on Technologies
Applied to Intelligent Electrical Networks, CITREI 2018, is organized.

Research works on the development or improvement of signal processing
techniques for condition monitoring applications are exposed at
scientific events that cover a significant number of topics about
prognostics and health management, non-destructive testing, etc., and
this event intends to gather researchers involved in a more specific
research field. The First ISSPCM will be held in Havana, Cuba, from
November 26th to November 30th, 2018, and it should provide a meeting
place for the researchers and industry specialists could exchange
knowledge and experiences.

Subject: Postdoc Position, Modeling of Dusty Plasmas

This proposal concerns numerical studies on high quality
nanodiamonds formation in miwrowave assisted plasma. the proposed
work consist of understanding the mechanisms that governs
nanoparticles (NPs) formation and growth to improve the process
using numerical simulations.

The post-doc will mainly focus on understanding the different
phenomena that govern the nanoparticle formation and plasma evolution
through modelling and comparison with experiments. The objective of
the modelling work is to accompany the experimental team to optimize
the process of NPs fabrication and control. The candidate will be
involved in the development of the chemistry scheme resulting in the
NP nucleation and particle growth. For this odel that follow particle
transport and growth will be used to predict the formation of carbon
NPs in the plasma. Extensive studies will be performed to understand
the phenomena that govern the NPs formation and size and quality which
are poorly understood and is critical in the development of several
carbonated NPs processes and is expected to produce publications
interesting for large audience.

Although the candidate will be working with the modelling group,
he/she will carry out extensive interaction with the experimental
group that produces (nano)diamond in MW plasmas. The results of this
study will also be used to describe a reduced scheme for particle
nucleation and growth that could be implemented by the group in the
in-house 2 dimensional self-consistent model constructed for MW
assisted plasmas for H2-meth[2, 3] The candidate will also have the
opportunity to interact with the molecular dynamics team of the lab
who are involved in calculating collision cross-sections.

1) The candidate should have a background in fluid dynamics / heat
transfer and chemistry. Knowledge of aerosol dynamics is a plus.
2) The candidate is expected to have fair programming skills,
preferably Fortran.
3) The candidate should be capable of carrying out research
independently and be able to regularly present his/her results to
other collaborating groups.

Duration of postdoc
The duration of postdoc is for a period of 1 year with a Gross
salary of around 2600 Euro (2100 Euro net) based on the experience.

Subject: PhD Position, Numerical Analysis, Univ of Zurich

The Computational Mathematics Group at the University of Zurich has an
opening for a PhD position for 3+1 years.

Topic: Development of an efficient numerical method to solve wave
equations in unbounded domains by space-time integral equation

Prerequisites: Master/diploma in Mathematics, very good knowledge in
numerical analysis and good knowledge in programming.

Application: In environmental physics there are applications where it
is essential to obtain information on material properties inside
(large) solid objects. For this purpose, typically, a wave is sent
into the solid and the scattered wave is recorded and used to solve
the relevant mathematical equations for the quantity of interest.

Cooperations: The proposal for this project has a concrete
application: to determine the ice volume of glaciers in Switzerland
(within a cooperation with the "Exploration and Environmental
Geophysics" group at ETHZ).

The software development will be a close cooperation with the
"Scientific Computing Group" at the University of Kiel.

Starting salary: CHF 58'800.

provides an excellent environment and infrastructure for their PhD
students. PhD students are members of the Zurich Graduate School in
Mathematics (ZGSM) which is jointly run with the D-Math at the ETH

Subject: PhD Position, UQ and Data Assimilation for Multiphase Flow, CWI

A PhD position is available in the Scientific Computing group at CWI,
the Dutch institute for mathematics and computer science. The
background of the project lies in developing new mathematical
techniques to combine the physical laws that govern fluid flows with
methods that can assimilate data into model predictions. The specific
goal is to arrive at real-time prediction of multiphase flow systems
such as slug flow in pipelines. This requires the use of reduced order
models that feature several uncertain (unclosed) terms. In this
project this closure problem is tackled through the real-time
incorporation of data. This data is available from high-fidelity
computational fluid dynamics (CFD) simulations or from experiments.

We seek a talented and enthusiastic candidate with a Master's degree
in Applied Mathematics, Physics, Aerospace Engineering or a related
discipline, and a specialization in Numerical Analysis or a related
field such as Computational Fluid Dynamics. You will be working
closely together with experts from both CWI (dr. Sanderse,
dr. Dubinkina and prof. Oosterlee) and Shell Technology Centre
Amsterdam (prof. Henkes). You will be enrolled in the Graduate School
of Delft University of Technology from which you will later receive
the PhD degree.
