1. Evaluation of Crack Depth Meter - An investigation of the crack depth meters possibilities and limitations for commonly occurring damage mechanisms
Master-uppsats, KTH/HållfasthetsläraSammanfattning : In this master thesis, the accuracy of the crack depth meter RMG 4015 was evaluated for different types of cracks with various damage mechanisms. In total, 61 crack depth measurements were conducted with the crack depth meter on 56 cracks which were located in the 23 different test pieces supplied by Kiwa. LÄS MER
2. Monitoring of Partial Discharges on Cable Terminations : An experimental approach to evaluate non-conventional online PD measurement techniques
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The transmission of electric power over long distances has historically posed challenges. However, the advent of high-voltage engineering has not only addressed distance barriers and power losses in electricity transmission and distribution, but it has also significantly improved the efficiency and transmission capacity of power grids.

3. Förstudie om tillståndsbaserat underhåll på Skanskas asfaltverk : Feasibility study about condition-based maintenance of Skanska’s asphalt plants
Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Skanska driver cirka 30 asfaltverk i Sverige. Något alla dessa verk har gemensamt är att driftsäkerheten är viktig då ett driftstopp på asfaltverket kan leda till höga kostnader ifallbeläggningsarbetet blir stillastående. LÄS MER
4. UsoniClean : Innovativt koncept för rengöring av LiDAR sensorer på personbilar
Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhetSammanfattning : Vision zero in traffic is something that car manufacturers and countries around the world strive for. To achieve this, safer and smarter cars are needed. Car manufacturers are introducing safety systems after safety systems to make it safer for the driver and other road users. One of these safety systems is LiDAR sensors. LÄS MER
5. Machine Learning of Laser Ultrasonic Data to Predict Material Properties
Master-uppsats, Linköpings universitet/Statistik och maskininlärningSammanfattning : The hardness of steel is an important quality parameter for several industrial applications. Conventional mechanical testing is used in quality testing for material hardness and the method is time-consuming, can cause material mix-ups, and results in material waste. LÄS MER
