Calculating the Accuracy and Precision of a Sonic and a IR Sensor

This exercise is intended to help students to understand the difference between accuracy and precision by means of performing multiple measures of distances by using the LEGO MINDSTORMS EV3 Ultrasonic and Infrared Sensor. In addition, the students should understand in which data format the measurements are recorded, stored and transfered between the sensor and the computer.

Cleaning up the Office: MATLAB 4.2c.1 (1995)

As I clean up the office, I found old MATLAB floppy disks and manuals. These are not the oldest ones I used, which were 3.5″ floppy disks with MATLAB 3.5, purchased in late 1992. Those I left at U Kiel when I moved to Potsdam in September 1995 after finishing my doctoral project. The floppy disks shown on the photograph are the first ones I bought when I got started here in Potsdam. Continue reading “Cleaning up the Office: MATLAB 4.2c.1 (1995)”

Presentation of the MATLAB/LEGO MINDSTORMS Practical on the Day of Teaching at U Potsdam

On the Day of Teaching at U Potsdam I will give a talk about the MATLAB/LEGO MINDSTORMS practical, sponsored by MathWorks Inc. The practical, part of the master’s courses “Geosciences” and “Remote Sensing, geoInformation and Visualization“, as well as of the Summer School on Earth Surface Dynamics, aims to  improve student’s skills to build efficient teams to solve typical problems in earth sciences in acquiring, processing and analyzing typical multispectral (visible, infrared, thermal), geophysical (seismic, magnetic) and geometric (2D, 3D) data.

Comment on “Young Researchers Better Avoid EGU Journal Climate of the Past”

I am one of the 4 Chief Editors of the journal Climate of the Past (CP) which is referred to in the article by Martin Trauth. I would like to thank Professor Trauth for his courtesy in letting me explain the publication system of CP so that young researchers can decide for themselves whether it is for them or not.
