MATLAB and Python Recipes for Earth Sciences
Martin H. Trauth, University of Potsdam, Germany
Yesterday the first paper about the MATLAB/LEGO MINDSTORMS Practical was published online in the European Journal of Physics, “Classroom-sized geophysical experiments: magnetic surveying using modern smartphone devices”, by Jens Tronicke and Martin H. Trauth. Continue reading “First Paper about the MATLAB/LEGO MINDSTORMS Practical Online!”
The XRF data from our sediment cores from the Chew Bahir show dramatic jumps. If we analyze them statistically, the results will be affected by these changes in the mean. That’s why I was looking for ways to remove them. Here are two of these ways to remove jumps. Continue reading “Removing Jumps in Time Series with MATLAB”
MATLAB is a great tool to simulate error propagation. As an example we will use the software to estimate the uncertainty in the difference between the measures of two quantities A and B, based on their individual uncertainties σA and σB. The experiment shows the error of differences in case the errors are either dependent or independent of each other.

Next week, according to the information of Springer-Nature, the proofs of the second edition of “MATLAB and Design Recipes for Earth Sciences” (MDRES) will arrive on my desk, now with a new title “Collecting, Processing and Presenting Geoscientific Information” and the old title as the subtitle. According to Springer-Nature, the Hardcover book will cost € 90.94, the eBook € 71.39. This is of course a lot of money, especially for students who need not only this, but many other books to study.

The 2nd edition of “MATLAB and Design Recipes for Earth Sciences” comes with a new title, to be published in March 2018! Continue reading “MATLAB and Design Recipes for Earth Sciences, 2nd Edition”
This exercise will show students how to capture thermal images, export them, import them to MATLAB, and calculate temperature readings. The Seek CompactPro does not allow the export of raw data, but only the images. Nevertheless, with a linear color palette it is possible to calculate and display quite good temperature values.
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 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”
