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)”
