  1. 1. Aurora-Imaging UAV Cameras

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

    Författare :Benjamin Girchman; Joel Widén; [2023]
    Nyckelord :;

    Sammanfattning : Ground based optical observations are limited by weather. One of the possible solutions is using adrone to fly above the clouds. This enables new approaches when planning experiments. The aim ofthis project is to produce and evaluate prototypes of aurora-imaging cameras that will be placed insideof such a drone. LÄS MER

  3. 2. Observations of Field-Aligned Currents and Their Role in Auroral Formation

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

    Författare :Maxim Uebel; Nikolaos Timoudas; [2023]
    Nyckelord :;

    Sammanfattning : Experimentally, it has been difficult to identify the exact physical processes atwork in the magnetosphere that drive the strong currents that later give rise to auroras. Theaim of this report has been to address this question by analyzing data gathered from Cluster-,MMS-, and DMSP satellite missions. LÄS MER

  4. 3. Cusp Aurora Appearing at the Dayside tip of Transpolar Arcs - Dependence on IMF and Dipole Tilt

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

    Författare :Cecilie Holmen; Mattias Wang; [2023]
    Nyckelord :;

    Sammanfattning : The aurora is a direct consequence of the Earth’s magnetic field interaction withthe solar wind and the interplanetary magnetic field (IMF). In this study, we examine thelocation of the cusp aurora when accompanied by transpolar arcs (TPAs) with the goal to finda dependence on the IMF. LÄS MER

  5. 4. Modelling Ganymede’s Aurora

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

    Författare :James Tammila; [2022]
    Nyckelord :;

    Sammanfattning : A 3D model of Ganymede’s aurora is created using captured data from the Space Telescope Imaging Spectrograph (STIS), on board the Hubble Space Telescope (HST). The data is processed into 24 images and analyzed. A 3D grid is generated around the moon to implement a functional model to describe the aurora. LÄS MER

  7. 5. Impact Investing in Venture Capital - Combining Impact with Financial Return: Case Study of Norrsken VC's Investment in Elypta

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

    Författare :Lucas Rintala; Emils Seilis; [2022]
    Nyckelord :Venture Capital; Impact Investing; Impact Assessment; Private Partnership Contracts;

    Sammanfattning : The purpose of this thesis is to investigate how an impact venture capital fund defines and measures impact, incorporates impact assessment in the decision-making process, and mitigates the multitasking problem. We perform an in-depth case study of Norrsken VC and its investment in the early-stage start-up Elypta. LÄS MER
