  1. 1. Investigating a possible dearth of stars with zero angular momentum in the solar neighbourhood.

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Author : Aayush Desai; [2023]
    Keywords : Galaxy: disk; Galaxy: fundamental parameters; Galaxy: kinematics and dynamics; Galaxy: nucleus; solar neighborhood; stars: kinematics and dynamics; Physics and Astronomy;

    Abstract : Background. Carlberg & Innanen (1987) first proposed the idea of measuring the solar re- flex velocity (the velocity of the Sun around the galactic centre), Vg,⊙, using the momenta of the stars in the solar neighbourhood. The proposal was a consequence of the work of L. READ MORE

  3. 2. Attitude and orbit control analysis of a solar sail spacecraft for Space sunshade missions in the vicinity of the sub-Lagrange 1 point

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Benjamin Jouanneau; [2022]
    Keywords : ;

    Abstract : This Master thesis report contains a complete attitude and orbit control analysis for solar sail spacecraft in the Circular-Restricted-3-Body-Reference frame. The overall goal of the project is to drive one solar sail from the edge of the Earth Sphere of Influence to a vicinity of the sub-Lagrange1 point. READ MORE

    Abstract : The transition in the transport sector by the integration of battery electric vehicles (BEVs) brings a new challenge for the system operators to ensure the balance between supply and demand. The installation of new EV charges poses a surge in electricity demand in the coming years which jeopardizes the grid reliability and stability. READ MORE

  6. 5. Early Design Stage Energy Optimization of Bysjöstrand Ecovillage, Sweden

    University essay from Högskolan Dalarna/Energiteknik

    Author : Anastasiia An; [2020]
    Keywords : Energy optimization; energy efficiency; passive design; active design; early design stage; neighborhood;

    Abstract : Decisions made at the early stage of building and settlement design can greatly influence the energy performance of the built environment. However, the type of feasible design intervention and their impact strong depends on project: if it is a new development or a re-development, whether the setting of the project is urban or rural, etc. READ MORE
