1. Improvement and verification of a pin-on-disc tribometer with variable speed and load
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The use of threaded fasteners can be found throughout the manufacturing industry due to their simplicity. When tightening a threaded fastener, the goal is to reach a desired clamping force. However, the clamping force is not directly measurable in production environments and the tightening torque is instead used to estimate the clamping force. LÄS MER
2. 3D Printing a Maxwell Fish Eye Lens With Periodic Structures
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : With the rise of high frequency communication systems such as 5G, new types of antennas has to be developed in order to meet the new requirements. In recent years, lens antennas made of periodic structures has been shown to have desirable performance when increasing operational frequency without increasing the size of the antennas. LÄS MER
