A tool for analyzing data from welding experiments

September 19, 2016

Some time ago a friend of mine, Prof. Gerard Wilhelm, asked me to develop a tool for analyzing data from his welding experiments. In this post I want to share some information about the tool, which we have developed in the following months. The tool is now running at the laboratory of Prof. Wilhem in Munich, Germany.

The following screenshot provides an overview over the features of the data anaylsis tool. On the left hand side the files are listed, which are loaded currently into the tool. Hereby, each file corresponds to one welding experiment, which are characterized by voltage and current measurements. When selecting a file, the lower part of the left hand side shows some properties of the selected experiment. These properties include statistical indicators such as minimum and maximum of timestamps, voltages, and currents. Furthermore, the mean and root variance of the voltages, currents, and powers (= voltages times currents) are provided. Finally, the center and the right hand side of the screen show different diagrams of the experiment data. In the upper parts the raw voltage and current measurements are displayed as timeseries charts. In the lower parts the voltage and current density functions as well as voltage-current point clouds are displayed.

Technically, the tool is implemented in the Java programming language using Apache Maven for build management. Furthermore, the user interface is based on Swing, Docking Frames, and JFreeChart. If you are interested in further information about the tool, please contact me at

Follow-Up on Denis' MSE Article

This is only a short/quick supplement to Denis' previous article about the Munich School of Engineering (MSE) colloquium. I uploaded my poster to show people some contents we presented and discussed with the other participants of the event. Hope you like it! ;-)

Official 3D Multi-Touch Websites

Recently, two websites went online about the 3D multi-touch prototype that I developed during my Master thesis at Fraunhofer FIT. They serve as the public hub for getting information about the technology, the project, and the people behind it. This step is intended to foster collaboration and intensify exchange with the community.

Teaser: Smart Traffic Control

Besides our original topics such as distributed and smart fride control we have worked on another interesting issue: Smart traffic control. By smart traffic control we mean the distributed routing and acceleration of traffic participants such that traffic jams are avoided (plus other minor objectives). This article features a first peak on the results of our work.
