  1. 1. Projective Geometry in Kinematics

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Emil Eriksson; [2024]
    Keywords : ;

    Abstract : In this thesis, we study projective geometry and show a connection to kinematics. We show how the group of rigid body motions in three-dimensional space can be parameterized on a hyperbolic quadric in a seven-dimensional projective space. We also show that this quadric is a geometry with triality, and we discuss triality from a kinematic viewpoint. READ MORE

  3. 2. Evaluation of Swedish daylight regulations in university building - Validation and applicability

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Cédric Berthou; [2024]

    Abstract : Daylight availability in buildings faces numerous challenges in a world where energy efficiency,thermal comfort, and sustainability take center stage. Daylight is well-known for its role in reducingartificial lighting consumption and enhancing the well-being and performance of building occupants. READ MORE

  4. 3. I sökandet efter en grundton : en reflekterande berättelse om konceptuellt tänkande inom landskapsarkitektur

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Emelie Lenning; [2024]
    Keywords : Konceptuell landskapsarkitektur; konceptutveckling; abstraktion; mening; storytelling; estetik; designmetod; designverktyg;

    Abstract : Landskapsarkitekter skulpterar, regisserar och komponerar våra livsmiljöer. Det är ett hantverk som kräver sin penna, sitt öra och ett känsligt sinne. Samtidigt befinner sig landskapsarkitekter i en kontext där en samhällelig utveckling knuffar regin in i stela processer och effektiviserade system (Bornemark 2018). READ MORE

  5. 4. Data analytics and machine learning for railway track degradation: Using Bothnia Line track measurements for maintenance forecasting

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign
