1. Making nets more acoustically visible : Floats as passive mitigation measures to reduce bycatch of harbour porpoise (Phocoena phocoena) in gillnets
University essay from SLU/Dept. Of Aquatic ResourcesAbstract : Incidental capture in fishing gear is today affecting at least 112 marine mammal species worldwide and for many smaller toothed whale species (Odontocete), gillnets are considered to be the largest problem. Although some effective mitigation measures exists, these are often context specific and many might be hard to implement due to reasons such as high costs and maintenance. READ MORE

2. Automation of High-accuracy Marking Tasks at MAX IV using the Quadrupedal Robot Spot
University essay from Lunds universitet/Institutionen för reglerteknikAbstract : When installing new research equipment at the synchrotron research laboratory MAX IV, a final positional accuracy of tens of microns is usually needed. To obtain that accuracy, initial reference points must be placed within 2 mm from the nominal target points in CAD, in a process referred to as bluelining. READ MORE

3. Automatic testing of optical sight adjustment screws by a robotic arm
University essay from Lunds universitet/Institutionen för reglerteknikAbstract : In this thesis the automation of an optical sight validation process was studied. The goal was to find a solution for controlling the position of a red dot in a red dot sight. A red dot sight is a non-magnifying reflector sight in which the user sees a red dot instead of a reticle. READ MORE
