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 σ_A and σ_B. 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.
