Rupture and shear waves in bi-material interfaces

I am modelling rupture in heterogeneous bi-material interfaces using FEM (Finite Element Method). I am planning to make this a part of my PhD thesis, see publications.

Mazzola (2007)

Mazzola is a software for modelling volumes of traffic. It provides tools for processing structural data, household surveys and other demographic or transport related data. Mazzola can be used on various platforms like Windows and Linux.

Way Models in Traffic Surveys (2007)

Household surveys can be used for examining the mobility of residents of certain areas. New ways of calculating the volume of traffic often demand further data.
The Dresden based consulting engineers IVAS had to make a decision about doing further surveys or finding a solution for working with low-redundancy data. I developed a model that allows estimating the mobility behaviour of people without additional surveys.

Metaquokka (2006)

Metaquokka is a JSR 168 compliant JAVA portlet, that can be loaded into the internet portal Gridsphere. It is used for manipulating XML data. I developed the portlet at the Earth Systems Science Computational Centre (ESSCC) in Brisbane, Australia.
Metaquokka is published under the MIT license and can be downloaded from Sourceforge in an older version. Parts of a documentation are located at the ESSCC internet portal. I am not involved in further development of the software.

Traffix (2002-2004)

The software Traffix 1.0 can be used to create generation and simulation models for road traffic. There is a special focus on highly modularized software and multiple visualisation forms of road networks and nodes.

Reference projects, where Traffix has been used for predicting future volume of traffic, are the traffic development plans of Gotha, Schmalkalden and Wittstock (all in Germany).

More detailed information about Traffix can be found here.

Structure from Motion (2005)

Information about the reconstruction of 3D objects from moving 2D images can be found at the TU Dresden website. This project is my Master thesis (Diplomarbeit).

Vehicle detection (2004)

This project was about analysing video streams, aiming to retrieve information about vehicles moving in street traffic scenes.

The vehicle detection problem was solved using structure from motion for retrieving three-dimensional information from two-dimensional images.

Steps to achieving the goal:

  • Evaluating algorithms - Newton's method with Graduated Non-Convexity (GNC) proved to be the best method
  • Programming in C++
  • Testing the algorithm under artifical and real-life weather conditions.

This project is my diploma-qualifying paper. Feel free to download it. The paper is in German language.

Programming of a Coupling Station (2005)

I implemented software for controlling an optical groupdelay measuring station. Programming was accomplished in LabView at the chair for radio frequency and photonics at TU Dresden.
Parts of the software already existed, I debugged it, added some functionality and optimised existing code.
