Apart from ,,simple´ fluid mechanical or structural mechanics problems for which commercial standard solutions exist, one can find a variety of complex mathematical problems found in industrial environments. For many of these complex issues, there are generally no established simulation solutions. Appropriate mathematical and computational methods are developed in mathematical research in the industry.

In this 2-day compact course present this in more detail, starting from a variety of practical problems of industrial basic research in the field of mathematical
methods. Among other things, we will consider the following practical issues:
* Passenger flow simulation for the optimal evacuation
* The methods of the polynomial chaos
* Crack development in structures
* Topology optimization

This Compact Course is organized in cooperation with Siemens AG Munich and will be held in German language.

The past decade has seen a growing trend of applying probability theory
to machine intelligence systems that deal with complex real-world data
with rich semantic structure and temporal and/or spatial dynamics.
Probabilistic graphical model is a formalism that exploits the conjoined
talents of graph theory and probability theory to build complex models
out of simpler pieces. It offers a powerful language to elegantly define
expressive distributions under complex scenarios in high-dimensional
space, and provide a systematic computational framework for
/probabilistic inference/. These virtues have particular relevance in a
wide range of application in scientific and engineering problems such as
computational biology, robotics, information science, finance, machine
learning, etc. In this lecture series, I will discuss the basic
mathematical underpinnings of graphical models---including
representation syntax, inference algorithms, and learning strategies.
Finally I will illustrate and discuss applications of graphical models
in computer vision, informational retrieval and natural language process.

Here are the specific topics I am going to cover:

Lecture 1 : Representation: A unified view of BN and MRF
Lecture 2 : Exact Inference: HMM and CRF
Lecture 3 : Learning: Multivariate Gaussian models, Gaussian graphical
models
Lecture 4 : Complex Graphical Models: topic models for text, image, and
network
Lecture 5 : Advanced topics: Nonparametric Bayesian Models

What is Software Engineering and how can it help me in developing better software? Software has become a solid part of research in many areas like physics, biology or medicine. It is used to simulate real world situations that are often too big or too small to be handles any other way. Error in Software can have an impact on research findings and at the end get very expensive. Researchers developing software for their own use would like to spend less time coding and concentrate on their research instead. They want to be able to trust the results the software is delivering.

Software Engineering is a profession and field of study dedicated to designing, implementing, and modifying software so that it is of higher quality, more affordable, maintainable, and faster to build (wikipedia). In this course you will learn about some essential Software Engineering principles and techniques. We will take a look at the different phases in a software development process (design, implementation, testing,…). You will learn to know the 10 software engineering practices (Version management, Issue Tracking,…) every scientific software project should use.

In the practical exercises we will take a look at some freeware Tools available to accomplish the benefits we have learned about in the lectures.

Good projects need money in order to be put into practice. In light of limited public funding, the securing of sources of financial support is an important task, especially in the academic sector.

Even though there is no garantueed path to reach the target, successful fundraising is not a coincidence. A prerequisite is an attractive project concept. In addition, professional skills and abilities are necessary in order to locate suitable funding sources and approach them with the right strategy.

The workshop communicates proven fundraising knowledge from the strategic initial considerations to the funding application.

Working as a PhD student you have the challenging task of developing research findings and write you doctoral thesis within three years. This alone is a demanding job. In addition, it is vital to the scientific process that your findings are presented to the scientific community. For most PhD students this is the first big project in their professional life and it could have a crucial impact on their future professional career. PhD students are highly motivated when they start their PhD studies but may underestimate the need for professional management for this three-year project \"doctoral thesis\".

This seminar demonstrates how to approach the doctoral thesis in a professional way. Project management tools and techniques are used, tailored to the specific situation of PhD students. You will learn how to set a project vision, define clear objectives, gain buy-in from your supervisor and other colleagues in your group, and how to develop a project plan, which is structured and at the same time flexible enough to easily adjust to unexpected findings. You will establish a \"controlling cycle\" which helps you to recognise risks and problems as early as possible, and you will learn how to manage critical situations and deal with ups and downs. Furthermore, networking with colleagues, supervisors and other people is an important topic of this seminar.

Throughout the seminar, you will work on your own doctoral thesis and share your experience with others. This seminar is most beneficial for PhD students who are in the early phases of their doctoral thesis. At the end of the seminar you will have established a strategy on how to approach your own doctoral thesis. During the follow-up REVIEW we will share experience and best practices and deal with open questions from the first module.

This seminar will help you to make the most effective use of your three years and finish your doctoral thesis on time. You will also learn and practise the basic concepts of project management - which are required in industry and research institutions.

Day 1: Fotography in Science & Research
Day 2: Documentary Photography - Theory & Practice
Day 3: Digital Postproduction

Teaching undergraduate students is an effective way to enhance your own knowledge about your research field. Additionally, you develop communication skills relevant for a career within or outside academia.

This two-day course covers the basics of professional University teaching. You will improve your methodological knowledge about the teaching-learning interaction and how that setting can be influenced effectively. The aim is to reach a level of learner centred teaching that leads to a deep-level learning approach on the side of the students. Hence, interaction with and motivation of the students is in the focus of this course.

* Basic principles of teaching and learning
* Understanding your role as a teacher
* Didactical planning of a course or lesson
* Defining learning objectives - designing learning activities
* Co-operative learning

Praktische Methoden der computergestützten Optimierung sind ein unverzichtbares Mittel für die optimale Auslegung und den optimalen Betrieb wichtiger Prozesse sowohl in Industrie und Wirtschaft als auch im Hochschul- und Forschungsbereich. Die Kenntnis dieser Methoden und der zugehörigen Software ist für die Berufspraxis von Mathematikern und Naturwissenschaftlern inzwischen immer wichtiger geworden. In der Vorlesung und den Übungen werden praktische Problemstellungen, Grundzüge der mathematischen bzw. informatischen Theorie, effiziente Algorithmen der beschränkten und unbeschränkten Optimierung und ihre Implementierung in Softwarepaketen behandelt. In den Übungen werden u. a. die vorgestellten Algorithmen untersucht, implementiert und praktisch angewendet.

Learning the basics of generation and visualization of numerical solutions of (mainly optimization) problems with different AG Bock software packages.

In diesem Seminar werden die biophysikalischen Aspekte der Signalwahrnehmung und Signalbearbeitung von verschiedenen biologischen Systemen diskutiert: Wie genau kann ein Signal (z.B. ein chemotaktischer Gradient) von einer Zelle oder von einem Organismus detektiert werden? Wie werden die Signale in der Zelle verstärkt und verarbeitet? Wie wird die Signalwahrnehmung durch externe oder interne Schwankungen beeinflusst, die in einem molekularen System unvermeidlich sind? Wichtige Modellsysteme für Prokaryoten und Eukaryoten, an denen diese Fragen experimentell untersucht werden, sind E. coli bzw. Lymphozyten.

The seminar covers basic topics on probabalistic graphical models.

Seminar talks can be held in German or English language. The seminar is also suited for doctoral students who are new to this field.

As part of the Greater Angkor Project, a multinational research group studying the diachronic archaeological landscape surrounding the temples of Angkor in Cambodia, ground-penetrating radar (GPR), has been extensively used in several research campaigns (2007-2010) to analyse subsurface features of the extensive water management system as well as the interior of temple enclosures.
GPR is a non-invasive geophysical survey method which offers, after the processing of data, a 3-dimensional view of the subsurface.
The survey has detected potential entry and exit channels of the giant reservoirs of Angkor, the baray, which sparked a new discussion on their function as part of the water management. Partly in combination with high resolution, but not ground-penetrating TerraSAR-X satellite radar data provided by the German DLR, the survey has revealed the existence of so far unmapped channels, enhancing our understanding of the water network at Angkor.
At Angkor Wat, a GPR survey in the enclosure has revealed the remains of a buried and demolished temple configuration that consisted of six definite and potentially as many as nine towers. They were enclosed by a rectangular wall in symmetrical alignment with the western entrance gate and the main axial causeway of Angkor Wat. Analysis of the GPR data was followed by excavations as part of the work of the Greater Angkor Project on occupation patterns in enclosures. The combined results now allow a discussion on the successive construction and demolition phases as well as occupation in the Angkor Wat enclosure.
The study indicates that the history of Angkor is not limited to its temples and what is visible on the ground. The presentation will include an introduction to the use of GPR and its functionality in Cambodia, and will provide interpretations to the most important discoveries of the survey.
Till Sonnemann (Dipl. geophys, Universität Münster, 2005) is member of the Greater Angkor Project at The University of Sydney, Australia, and PhD candidate at the university`s Department of Archaeology.

The aim for this seminar is to review a wide range of research on the subject of the title including both classical works and the work of the speaker’s research team over the past
decade. Definitions and descriptions of droplet arrays, groups, and sprays will be
presented. The classical works of the 1971-81 period will be reviewed briefly. Recent
research on transient burning and vaporization of finite arrays with Stefan convection will
be presented, including extensions to non-unitary Lewis number and multi-component,
liquid fuels. As important background information, recent results on transient, convective
burning of a single droplet will be examined. Research on transient convective burning of
infinite (doubly periodic and periodic) and finite droplet arrays will be discussed. Effects
of droplet deceleration due to aerodynamic drag, diameter decrease due to vaporization,
internal liquid circulation, and multi-step chemical kinetics will be discussed. Special
attention will be given to flame structure as a function of spacing between neighboring
droplets and Damkohler number: individual droplet flames versus group flames and wake
flames versus envelope flames. Potential future works on droplets moving in tandem,
staggered arrays, and stability of arrays will be briefly described.
