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

Introducing Timeline Navigation and Facebook Like

To improve the usability of my blog I worked on two new features: (1) The timeline navigation and (2) the Facebook like button. When reading an article, the timeline navigation allows exploring the remaining blog articles in chronological order. Instead, the Facebook like button provides information about how interesting a given article is for the community.

Augmented Reality Framework Screenshot.

Last year I started developing an augmented reality framework with a friend of mine from electrical engineering science. We succeeded in providing a QT user interface and connecting to a webcam using the Video 4 Linux API.

Software logo sketches with graphics tablet/pen.

In a previous article I showcased some logo ideas I created with Inkscape and Gimp. In the mean time I bought a Tablet PC with Stylus and discovered a little tool called MyPaint. As I would like to demonstrate in this article, this combination is great for logo sketching: It's fast, flexible, and sophisticated at the same time!
