  1. 1. THE COVID-19 PANDEMIC'S IMPACT ON THE PERCEPTION OF CLIMATE CHANGE IN THE EU

    Kandidat-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Patricija Viksne; [2023-03-08]
    Nyckelord :Climate change; COVID-19 pandemic; climate change perception;

    Sammanfattning : The study examines how individuals’ perceptions of climate change as a threat have changed due to the COVID-19 pandemic in Western and Eastern Europe. Different psychological theories about psychological links to the pandemic and climate change, psychological mechanisms, and the finite pool of worry effect were used to understand how the experience of the COVID-19 pandemic could affect individuals’ perception of climate change as a threat.

  3. 2. Evaluation of a computational method for natural fiber-reinforced plastics

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Anna Lim; [2023]
    Nyckelord :PPNF; Composite material; fiber orientation; natural fiber; coupled analysis; PPNF; Kompositmaterial; fiberorientering; naturfiber; kopplad analys;

    Sammanfattning : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. LÄS MER

  4. 3. Effect of the ICRH Antenna Position on the Coupled Power in ITER and JET

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

    Författare :Olle Sundberg; Vincent Forsberg; [2023]
    Nyckelord :;

    Sammanfattning : Fusion energy has fascinated scientists for decades. One reason we do not see thispromising energy source powering today's society is the fact that the process requires extremeplasma temperatures. LÄS MER

  5. 4. Plastic deformation of hot riveted joints acting in shear

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Victor Gard; [2023]
    Nyckelord :;

    Sammanfattning : A popular way to maintain old rivet connections is to reuse the old connection and replace the old rivets with high grade steel bolts. In doing so the behavior of the joint can change due to the new geometry, where a gap between the new bolt and the rivet hole emerges. LÄS MER

  7. 5. Bedömning av prediktiv förmåga för Finita Elementberäkningar med optisk töjningsmätning (DIC)

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Albin Zetterqvist; Linus Hjelm; [2023]
    Nyckelord :Digital image correlation; Finite element; Predictive capability; Model calibration; FEM; DIC; Modellkalibrering;

    Sammanfattning : The goal of this thesis is to improve the predictive capability of Finite element (FE) by gathering data from experimental test and implement the characteristics into the material model that is used. FE is a commonly used method to predict the mechanical behavior of materials and components during applied forces. LÄS MER
