MRES Exercise #14 PCA To Classify Minerals in Granite
Color is an uncertain characteristic for the determination of minerals. Many minerals occur in a variety of different colors. Examples are quartz with its color variants amethyst, rose quartz or smoky quartz or feldspar with color variants like amazonite. However, if the minerals in a rock are reliably determined, their different coloring can be used to quantify them. Continue reading “MRES Exercise #14 PCA To Classify Minerals in Granite”
MRES Exercise #7 GPS Tracking using MATLAB Mobile, Part 2
Solution “MATLAB Mobile GPS Paperchase” – Update February 2020
MathWorks has changed the MATLAB Mobile Sensor Logs data type to timetable. The sample data set and the script for evaluating it changes accordingly.

MRES Exercise #12 Smartphone Seismometer
The increasing spread of mobile internet devices with built-in accelerometers led to the idea of using them to build up low-cost seismological arrays (Minson et al 2015, Kong et al. 2017). Continue reading “MRES Exercise #12 Smartphone Seismometer”
MRES Exercise #11 Dip and Dip Direction using Smartphones
The following exercise is intended to help to understand the measurement of the orientation of linear and planar structures in the field, using the magnetometer and the gyroscope of the smartphone. We will carry out a large number of repeated measurement, not possible with a traditional compass in a reasonable time. These repeated measurements will be statistically evaluated and interpreted with regard to their accuracy and precision.

MRES Exercise #9 Getting Started with MATLAB
This exercise helps students to get started with MATLAB. During the first part, the students are asked to go through the 2–3 online tutorial “MATLAB Onramp”, available online at the MATLAB Academy to get familiar with the MATLAB fundamentals. Second, the students are asked to obtain information on a specific MATLAB function from the documentation. And third, the students are asked to create a simple MATLAB function.

MRES Exercise #8 Thermal Imaging using the Seek CompactPro
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.
