Workshop

"Bangkok Summer School on Applied Mathematics & Computational Science"

March 20-24, 2017

The Bangkok Summer School on Applied Mathematics & Computational Science, jointly organized by Chulalongkorn University and Interdisciplinary Center for Scientific Computing (IWR) of Heidelberg University, will take place from 20th-24th March 2017 at the heart of Bangkok in Thailand’s most prestigous university- Chulalongkorn. The summer school will be conducted by leading experts from the two most renowned universities of Asia and Europe.

The summer school is designed for postgraduate students, young researchers and scientists in the field of applied mathematics and numerical methods. All lectures start at the postgraduate level and give short introductions to the general theory in the field, specializing in more specific topics during the lecture.

The Bangkok Summer School on Applied Mathematics & Computational Science provides a perfect opportunity for you to meet with all the leading experts in the field of Scientific Computing.

"Analytical approximations for spatial stochastic gene expression in single cells and tissue"

Dr. Ramon Grima • University of Edinburgh, UK
March 8, 2017 • 11:00

Gene expression occurs in an environment in which both stochastic and diffusive effects are significant. Spatial stochastic simulations are computationally expensive compared to their deterministic counterparts and hence little is currently known of the significance of intrinsic noise in a spatial setting. I will show how starting from the reaction-diffusion master equation (RDME) describing stochastic reaction-diffusion processes, we can derive closed-form expressions for the approximate steady-state mean concentrations which are explicit functions of the dimensionality of space, rate constants and diffusion coefficients. These are generally different from those given by the deterministic theory of reaction-diffusion processes, thus highlighting the importance of intrinsic noise. Our theory is confirmed by comparison with stochastic simulations, using the RDME and Brownian dynamics, of two models of stochastic and spatial gene expression in single cells and tissues. Lastly, time permitting, I will discuss how one can extend these results to stochastic spatial simulations of intracellular processes which take into account macromolecular crowding, namely the volume exclusion due to the finite size of molecules.

Discussion with the speaker after the talk (at around 12:00), coffee will be provided.

IWR-Colloquium Winter Term 2016 / 2017

"Music Information Retrieval - When Music meets Computer Science"

Prof. Meinard Müller • International Audio Laboratories Erlangen (AudioLabs), Fraunhofer IIS & Friedrich-Alexander-Universität Erlangen-Nürnberg
February 1, 2017 • 16:15

Significant digitization efforts have resulted in large music collections, which comprise music-related documents of various types and formats including text, symbolic data, audio, image, and video. In the field of music information retrieval (MIR) great efforts are directed towards the development of technologies that allow users to access and explore music in all its different facets. For example, during playback of some CD recording, a digital music player may present the corresponding musical score while highlighting the current playback position within the score. On demand, additional information about melodic and harmonic progression or rhythm and tempo is automatically presented to the listener. A suitable user interface displays the musical structure of the current piece of music and allows the user to directly jump to any key part within the recording without tedious fast-forwarding and rewinding. In this talk, I discuss a number of current research problems in the field of music information retrieval and indicate possible solutions. One fundamental problem is to decompose a given music signal into semantically meaningful components. To guide the decomposition, one may exploit additional information, either in the form of specific acoustic properties of the components or in the form of additional score information. As an example, I show how to compute a notewise decomposition of a music signal by applying a score-informed variant of non-negative matrix factorization (NMF). Finally, I discuss various audio editing and manipulating applications to highlight the potential of these decomposition techniques.

IWR-Colloquium Winter Term 2016 / 2017

"Finite dimensional state representation of linear and nonlinear delay systems"

Prof. Mats Gyllenberg • University of Helsinki, Finland
January 11, 2017 • 16:15

We consider the question of when delay systems, which are intrinsically infinite dimensional, can be represented by finite dimensional systems. Specifically, we give conditions for when all the information about the solutions of the delay system can be obtained from the solutions of a finite system of ordinary differential equations. For linear autonomous systems and linear systems with time-dependent input we give necessary and sufficient conditions and in the nonlinear case we give sufficient conditions. The ideas and results are illustrated by models for infectious diseases and physiologically structured populations.
