1. Relationship between Fatigue Properties and Surface Treatment of Aluminum Alloy
H-uppsats,Sammanfattning : Corrosion has posed a significant challenge within the maritime sector for numerousyears. In the 21st century, bolstering the corrosion resistance of alloys, particularlyaluminum alloys, has become paramount. Aluminum alloys find widespread use inpropulsion systems, boat hulls, and cargo vessels. LÄS MER
2. Life extension of welded steel details in bridges
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : High-Frequency Mechanical Impacts (HFMI) is a surface treatment technique utilized to introduce residual stresses and extend the service life of structures. This project primarily focuses on studying the life extension effects of HFMI on welded structures that have undergone fatigue and have existing cracks. LÄS MER
3. Data Augmentations for Improving Vision-Based Damage Detection : in Land Transport Infrastructure
Master-uppsats, KTH/Lantmäteri – fastighetsvetenskap och geodesiSammanfattning : Crack, a typical term most people know, is a common form of distress or damage in road pavements and railway sleepers. It poses significant challenges to their structural integrity, safety, and longevity. Over the years, researchers have developed various data-driven technologies for image-based crack detection in road and sleeper applications. LÄS MER
4. Development of thick GaN and AlGaN drift layers for vertical power devices
Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenSammanfattning : High-quality, thick III-nitride epitaxial drift layers with controlled doping are needed for next-generation highly efficient vertical power devices for a smart grid applications and electrification of mobility. Achieving desirable material properties, such as low background impurity concentrations and reduced dislocation densities in combination with high growth rates, necessary for practical application present a challenge.

5. Sprickorna i Konstnärsförbundets styrelse
Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvårdSammanfattning : All oil paintings do degrade with time and a clear sign of this ageing is the cracks seen at the surface of the painting. Cracks can , however, also be hidden underneath the very surface and in fact extend all the way down to the very substrate. LÄS MER
