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.
The paperchase exercise is intended to help students to understand how to use sensors of mobile devices connected to a server via MATLAB Mobile. We used a laptop in the classroom, connected to the internet via WiFi, and a smartphone, connected to the internet via mobile internet connection. Continue reading “MATLAB Mobile GPS Paperchase”
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)”
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.
Years ago my former doctoral student submitted a manuscript to the open access/open review EGU journal Climate of the Past. The manuscript about past climate variations in southern Ethiopia undoubtedly had its weaknesses and received negative reviews – and got rejected by editor Martin Claussen. Unfortunately, the rejected article along with reviews remains visible online at the CoP webpage and since then inspires reviewers of follow-up manuscripts submitted to other journals.
