1. Ion Induced Particle Desorption From Self Supporting Nanomembranes : Influence of Different Geometries and Particle Types
Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysikSammanfattning : Nanoelectronics is a field undergoing rapid development, meaning knowledge of the materials and methods used in nano-scale systems is a driving force in the industry. Silicon is a well known material in nanoelectronics commonly used as a semiconductor and is therefore a good representative for nanomaterials in general. LÄS MER
2. The Effect of High Wheel Impact Load on the Rail Reliability - a Case Study at Bodsjön
Master-uppsats, KTH/SpårfordonSammanfattning : This study focuses on the reliability of railway track in the relation with high loads resulted from wheel damages, where higher (dynamic) vertical wheel loads are expected from trains with damaged wheels. The Swedish Transport Administration (Trafikverket) has monitored and recorded data of rail defects and breaks. LÄS MER
3. Estimation of the characteristic in-situ compressive strength class of concrete structures - A case study of the Skuru bridge
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : It is inevitable that Structures become older and their intended use changes or the structuralcodes regulations change. In some regions the damage from seismic activities is a possibility.It becomes, therefore crucial to assess the structural capacity of such structures. LÄS MER
4. Detektion och klassificering av äppelmognad i hyperspektrala bilder
Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakultetenSammanfattning : Detta arbete presenterar en icke-destruktiv metod för att detektera och klassificera mognadsgraden hos äpplen med användning av hyperspektrala bilder. Fastställning av mognadsgraden hos äpplen är intressant för bland annat äppelodlare och musterier vid lagring och beredning. Äpplens mognadsgrad är även intressant inom växtförädling. LÄS MER
5. Non-destructive Evaluation of Ultrasound Contrast Agent
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : Clinical ultrasound imaging techniques can be greatly improved by the use of ultrasound contrast agents (UCAs). While microbubbles (MBs) without shell are unstable and cannot be used for practical applications,a shell produced from biocompatible polyvinylalcohol (PVA) significantly improves chemical versatility and stability.
