1. 1. Review and Design of DC Electrical Field Measurement Systems and Related Developments : For Measurements Around HVDC Cable Terminations

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Emil Bergvall; [2023]
   Nyckelord :DC Field Probe; Measurement Systems; Electric Fields; Cable Termination; Ion Drift; Conductivity; HVDC; Field Mill; Field Simulations; Positioning System; MEMS; Electro-Optics; DC Fält Prob; Mätsystem; Elektriska Fält; Kabelavslut; Jondrift; Ledningsförmåga; HVDC; Fältkvarn; Fält Simulationer; Positioneringsystem; MEMS; Elektro-Optik;

   Sammanfattning : With power generation and consumption placed further away from each other, with for example increased offshore power production, the need for HVDC transmission systems increases. As voltage levels in the HVDC transmission system are raised, the losses can be decreased, enabling efficient power transfer over longer distances. LÄS MER

3. 2. Effect of post-treatment of cemented carbide : Microstructural investigation and evaluation of mechanical properties of cemented carbide inserts for rock tool applications

   Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

   Författare :Jessica Jacobs; [2021]
   Nyckelord :;

   Sammanfattning : Cemented carbides are used in rock tool applications by reason of their beneficial mechanical properties, i.e. a combination of high toughness, wear resistance and hardness. The cemented carbides commonly receive their hardness from tungsten carbides (WC) whereas cobalt (Co) is the dominating binder material. LÄS MER

4. 3. Influence of hydrogen on mechanical properties, microstructure and fracture surface of stainless steel 316L and stainless steel 304

   Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Mustafa Adnan Tawfeeq Salman; [2020]
   Nyckelord :Hydrogen embrittlement; stainless steel; microstructure; hydrogen charging; slow and fast strain rate.; Väteförsprödning; rostfritt stål; mikrostruktur; väte laddning; långsam och snabb töjnings hastighet;

   Sammanfattning : Since hydrogen is an alternative energy source and has both economic and environmental benefits, it has received more attention. To use hydrogen a certain condition must be met, safe pressurized containers which are often made of metal. The metal isrequired due to the high mechanical strength and reasonable cost. LÄS MER

5. 4. Artificial intelligence together with mechanical imaging in mammography

   Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

   Författare :Anna Bejnö; [2019]
   Nyckelord :Medicine and Health Sciences;

   Sammanfattning : Artificial intelligence (AI) and mechanical imaging (MI) have been used in separate studies in breast imaging. They have individually shown great possibilities within the field of mammography, but the use of the two techniques together have never been evaluated. LÄS MER

7. 5. Fatigue Life Analysis of Weld Ends : Using FE-Calculations and Mechanical Testing

   Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Victor Ljungdahl; [2018]
   Nyckelord :Comparison; Effective notch method; Testing; Weld End; Jämförelse; Effective notch metoden; Provning; Svetslut;

   Sammanfattning : Fatigue life estimation of welds is a complex issue since the characteristics of each weld are unique depending on load case, geometry and properties. Fatigue life estimation on weld ends is limited and often the weakest point of a weld. LÄS MER
