1. 16. Self-Supervised Learning for Tabular Data: Analysing VIME and introducing Mix Encoder

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen

   Författare :Max Svensson; [2024]
   Nyckelord :Machine Learning; Self-supervised learning; AI; Physics; Medicine; Physics and Astronomy;

   Sammanfattning : We introduce Mix Encoder, a novel self-supervised learning framework for deep tabular data models based on Mixup [1]. Mix Encoder uses linear interpolations of samples with associated pretext tasks to form useful pre-trained representations. LÄS MER

3. 17. Structural analysis of HZO thin film and electrode using X-ray diffraction

   Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Elliot Winsnes; [2024]
   Nyckelord :HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

   Sammanfattning : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. LÄS MER

4. 18. Kartläggning av fysiskt aktiva unga kvinnor och mäns självskattade stress och livskvalitet : en tvärsnittsstudie

   Kandidat-uppsats, Uppsala universitet/Fysioterapi och beteendemedicin

   Författare :Rebecca Blomqvist; Iris de Ridder; [2024]
   Nyckelord :mental health; physical activity; stress; quality of life; young adults;

   Sammanfattning : Bakgrund: Unga vuxna rapporterar högst grad av psykisk ohälsa jämfört med andra åldersgrupper, och stress är en vanlig orsak till sjukskrivning. Fysisk aktivitet har visats vara en ”skyddande” faktor för psykisk ohälsa, till exempel höjer livskvalitet. Trots detta tycks psykisk ohälsa förekomma även i denna grupp. LÄS MER

5. 19. "Boeing is deeply saddened..." : En kvalitativ innehållsanalys av Boeings kriskommunikation efter 737 MAX-krisen

   Kandidat-uppsats, Jönköping University/HLK, Medie- och kommunikationsvetenskap

   Författare :Elsa Stefansson; Ellen Svensson Ödmar; [2024]
   Nyckelord :;

   Sammanfattning : This thesis conducts a qualitative content analysis of The Boeing Company's crisis communication during the 737 MAX crisis in 2019, with a focus on the crisis involving Boeing's 737 MAX aircraft, Ethiopian Airlines Flight 302. Applying the Situational Crisis Communication Theory (SCCT) and an ethical framework, the study examines Boeing's crisis communication and how the organization deals with ethical and moral dilemmas and how these are expressed.

7. 20. Prospects for a Free Electron Laser at the FemtoMAX Beamline

   Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Johan Holmberg; [2024]
   Nyckelord :Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

   Sammanfattning : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.
