  1. 31. Prototypmetoder för hornhögtalare

    Master-uppsats, Lunds universitet/Innovation

    Författare :Linn Andersson; Alice Nivestam; [2022]
    Nyckelord :prototyping; additive manufacturing; horn loudspeakers; acoustics; mechanical engineering; Technology and Engineering;

    Sammanfattning : The aim of this project was to investigate suitable prototyping methods to be used during the development of horn loudspeakers. Different methods were tested to investigate how well they replicated the original loudspeaker based on acoustical performance. LÄS MER

  3. 32. Does Mandatory Sustainability Reporting Decrease ESG-rating Disagreement? A Difference in Differences study on the EU Non-Financial Reporting Directive

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Hugo Christensson; Elias Horn Maurin; [2022]
    Nyckelord :Corporate Social Responsibility; ESG Rating Disagreement; ESG Rating Agencies; Regulation; Disclosure;

    Sammanfattning : ESG-ratings are explicitly incorporated in investment decisions by investors with $121 trillion AUM. Ratings are based on diverse sustainability data, which is collected and synthesized by raters with different methodologies. The scores for identical stocks across raters have an observed correlation of 0. LÄS MER

  4. 33. Sino-American Rivalry in Djibouti: What Impact Has It on the Existing Conflict in the Horn of Africa?

    Kandidat-uppsats,

    Författare :Yahya Shebeshir; [2022]
    Nyckelord :;

    Sammanfattning : Although the great power rivalry has dominated the International Relations (IR) scholarship since the end of WWII, the mainstream Global IR discipline has not well incorporated the thoughts of IR scholars outside the core Western countries (Achariya, 2014). More specifically, how this rivalry creates safe havens for authoritarian regimes in developing countries and how that nurses a vicious circle of war in many regions of the world has attracted less attention in the field of IR.

  5. 34. Driving forces of spatial cognition : Is the car a mover in egocentric distance estimation?

    Kandidat-uppsats, Uppsala universitet/Kulturgeografiska institutionen

    Författare :Martin Horn; [2022]
    Nyckelord :distance cognition; modal choice; action-specific perception; car driving; urban planning;

    Sammanfattning : Physical inactivity is a cause of health problems globally that cause suffering for people and amass significant costs for states. One way of improving physical activity is by formulating policy and implementing planning decisions that encourage active travel. At the heart of the issue, however, lies the matter of modal choice.

  7. 35. Whole-body SAR measurements of 5G mmW base stations in a reverberation chamber

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

    Författare :Jens Eilers Bischoff; [2022]
    Nyckelord :Reverberation chamber; Whole body specific absorption rate; 5G; Absorption; Antenna measurements; Modväxlande kammare; Helkroppsbaserad specifik absorptionshastighet; SAR; 5G; Absorption; Antennmätningar;

    Sammanfattning : This study presents a method for measurement of whole-body average specific absorption rate (WBSAR) of a millimeter wave (mmWave) antenna in a reverberation chamber. The method takes advantage of multiple radiated power measurements to estimate the power absorbed in a phantom placed in front of the antenna. LÄS MER
