1. 11. Identification of Fibers in Micro-CT Images of Paperboard Using Deep Learning

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

   Författare :David Rydgård; [2023]
   Nyckelord :Fiber networks; Paperboard mechanics; Deep learning; Tomography; Image analysis; Technology and Engineering;

   Sammanfattning : This master thesis project explores the possibility of using deep learning to segment individual fibers in three-dimensional tomography images of paperboard fiber networks. We test a method which has previously been used to segment fibers in images of glass fiber reinforced polymers. LÄS MER

3. 12. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/FREIA

   Författare :Karl-Fredrik Boholm Kylesten; [2023]
   Nyckelord :attosecond; free-electron laser; XFEL; self-amplified spontaneous emission; SASE; tapering; energy modulation;

   Sammanfattning : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. LÄS MER

4. 13. Unlocking dynamic capabilities through knowledge management strategies in a start-up context : A case study on a knowledge-intensive start-up company

   Master-uppsats, Uppsala universitet/Industriell teknik

   Författare :Rasmus Bergshem; David Gustafsson; [2023]
   Nyckelord :Knowledge management; Dynamic capabilities; Knowledge-intensive; Start-up;

   Sammanfattning : This research is a qualitative case study at the knowledge-intensive start-up company Magstrom. The purpose of the study is to investigate and thus understand how knowledge management processes can be utilized to facilitate dynamic capabilities within a knowledge-intensive start-up context.

5. 14. Experimental studies of radiation damage in uranium nitride

   Master-uppsats, KTH/Fysik

   Författare :Maria Giamouridou; [2023]
   Nyckelord :uranium nitride nuclear fuel; advanced nuclear fuel; uranium nitride fabrication; uranium nitride characterisation; Spark Plasma Sintering; proton irradiation; irradiation damage; TANDEM accelerator; irradiation induced cracking; irradiation induced hardening; irradiation induced swelling; hydrogen implantation; dislocation loops; kärnbränsle av urannitrid; avancerat kärnbränsle; tillverkning av urannitrid; karakterisering av urannitrid; Spark Plasma Sintering; protonbestrålning; strålningsskador; TANDEM-accelerator; strålningsinducerad sprickbildning; strålningsinducerad härdning; strålningsinducerad svällning; väteimplantation; dislokationsloopar;

   Sammanfattning : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. LÄS MER

7. 15. Navigating the Growth Paradox in an Incumbent Business Context : Managerial Implications from a Degrowth Perspective

   Master-uppsats, Umeå universitet/Företagsekonomi

   Författare :Sabrina Dietrichs; Gitte Thorsén; [2023]
   Nyckelord :Degrowth; Degrowth Frameworks; Growth Paradigm; Growth Paradox; Organizational Paradox Theory; Managerial Paradox Response; Post-Growth Economy;

   Sammanfattning : Our study investigates how the organizational growth paradox is perceived and managed by incumbent firms from a degrowth perspective. There is a growing critique against the growth paradigm, an increasing support for its abandonment. Scholars are calling for a paradigm shift towards a post-growth economy. LÄS MER
