This course provides an introduction to the programming language R. The first part of the course, giving 1.5 ECTS credits, will take place in week 3 of 2016 (18-22 January). It will be taught by

An optional second part of the course offers individual consultation on using R in specific research problems, potentially for additional credit.

The course consists of the following modules:

- Astrostatistics: Past, Present & Future
- Getting started with R and CRAN
- Density estimation & local regression
- Fundamentals of statistical inference
- Regression
- Multivariate clustering & classification
- Bayesian inference
- Bayesian computation
- High performance computing in R
- Towards good statistical practices in astronomy

Domain Decomposition is an important concept in the parallelization of numerical methods for partial differential equations (PDEs). Thereby, the spatial domain is decomposed into several parts, which are assigned to different processes, which then communicate over the boundaries of these domains. Naturally the question arises what happens if we modify the data or reduce the amount of communication. For large classes of PDEs, practical answers can be found by mathematical analysis, which turns out to be relevant to other multiphysics problems such as fluid structure interaction as well.

The course will cover the basic theory of domain decomposition methods for model problems like the Poisson and the Heat Equation with finite difference discretizations and then look at the practical issues of implementing these in a Message Passing Interface (MPI) framework.

The course gives a basic introduction to techniques for simulating complex systems and processes, typically with many coupled degrees of freedom. The main aim of the course is to introduce the students to applications of these techniques. To this end, the course contains five one-week projects in different areas (astronomy, biophysics, elementary particle physics, medical radiation physics and physical/theoretical chemistry).

Teachers: Melvyn B. Davies, Anders Irbäck, Per Linse, Michael Ljungberg and Leif Lönnblad/Torbjörn Sjöstrand

**Modelling and computer simulation of particles and nuclides passage through
matter and magnetic field, with Geant4 as example** (7-11 April 2014, 3 ECTS)

Geant4 is a toolkit for simulating the passage of particles through matter. It
is the reference simulation engine in many areas. Geant4 covers all relevant
physics processes, electromagnetic, hadronic, decay, optical, for long and
short lived particles, for energy range spanning from tens of eV to TeV scale.
The transport of low energy neutrons down to thermal energies is also be
handled. The software can also simulate remnants of hadronic interactions,
including atomic de-excitation and provides extension to low energies down to
the DNA scale for biological modelling.

The course concerns the following topics: Introduction to simulation of
elementary particles and nuclides passing through and interacting with matter;
structure of a simulation program based on object-orientation; definition of
realistic geometry including magnetic field; primary particles and interfaces
to generators; electromagnetic and strong interaction physics processes; user
interfaces; visualization; event biasing; simulation examples from subatomic
physics, space science and medical applications.

**Grid computing concepts and tools** (study period II, 4.5 ECTS)

The course gives introduction into concepts of Grid computing, discussing
aspects of authentication and authorisation, interfaces to computing services,
distributed storage and data handling, resource characterization and discovery,
information representation and monitoring, workload management and scheduling
in a distributed environment. It will introduce concepts of Grid certificates
and trust, Virtual Organisations, Grid jobs, meta-protocols, information
systems, brokering and runtime environments. Existing tools and services will
be introduced. The students will obtain Grid certificates and a temporary
access to a Grid testbed for exercises. The course will be a combination of
lectures and hands-on tutorials.

Teachers: Oxana Smirnova, Balazs Konya

**Efficient programming of modern HPC architectures** (study period I,
7.5 ECTS)

The course discusses programming techniques required to efficiently utilise
high performance computing in a PhD-project in computational science and
engineering. The course content includes developing modularised software in
Fortran 95 and the scripting language Python. You will be taught how to conduct
an object-oriented analysis of common problems in science and engineering.
Parallel programming will be another focus point of the course. We will
discuss shared memory and distributed memory programming. The course will
introduce the application interfaces of OpenMP and MPI as well as the concepts
behind these.

Teachers: Joachim Hein, Jonas Lindemann

**Image analysis** (study period II, 7.5 ECTS)

The main aim of the course is to give a basic introduction to theory and
mathematical methods used in image analysis, to an extent that will allow
image processing problems to be developed and evaluated. In addition the aim
is to help the PhD student develop his or her ability in problem solving, both
with and without a computer. Furthermore, the aim is to prepare the student
for further studies in computer vision, multispectral image analysis, machine
learning and statistical image analysis.

It is assumed that the students following the course selects a project before the course starts.

The course is divided into logical modules:

- Module 1 - Introduction to images and to image analysis systems. Linear algebra for images. The convolution operator and the Fourier transform and their relation to each other. Detection. Understanding of filter types (low-pass, high-pass, band-pass and band-reject), definition of image quality and strategies for image optimization.
- Module 2 - Discretization of continuous signals, and associated errors. Image interpolation. The discrete Fourier transform. Multimodality image registration, Applications
- Module 3 - Image segmentation and voxel classification in general. Thresholding. Segmentation using energy methods, Segmentation using snakes. Level set methods. Tracking. Applications.
- Module 4 - Visualization and screen representation, color coding, alpha channel, contrast, transparency, histogram equalization, Applications.
- Module 5 - Image reconstruction of 3D volumes from 2D projections. Analytical methods, Iterative Methods. Noise models. Applications.
- Module 6 - Image system development and evaluation. Monte Carlo simulations of imaging systems, Observer studies. Applications.
- Module 7 - Machine learning for image classification and clustering. Methods includes neural networks, support vector machines, random forests and self-organizing feature maps. Applications

During the course, homework assignments are made on data specific to the students' individual projects with methods taught in the different modules. The course ends with project presentations.

** Computational tools and recipes** (study period I, 7.5 ECTS)

The aim of this course is to equip the participating PhD students with the
tools needed to solve advanced numerical problems efficiently in their
research. Topics will be taken from the book, "Numerical Recipes" by Press et
al., and include sorting, root finding, interpolation and extrapolation,
minimization and maximization of functions, fitting procedures and modeling of
data, and Fast Fourier transforms. The course will be a mixture of lectures
and hands-on exercise sessions given by experts from a number of departments.
