  1. 1. Risk Assessment for Space Debris Collisions

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Kenny Andersson; [2023]
    Nyckelord :space debris; NASA standard breakup model; satellite fragmentations; satellite fragmentation modelling; space surveillance and tracking; ESA MASTER; collision risk; risk assessment; space situational awareness; rymdskrot; NASA standard breakup model; satellitfragmentering; modellering av satellitfragmentering; inmätning och övervakning av rymdobjekt; ESA MASTER; kollisionsrisk; riskbedömning; rymdlägesbild;

    Sammanfattning : The increasing reliance on space infrastructure and its rapid expansion necessitate the development and enhancement of tools for space debris and fragmentation research. Accurate prediction of the risks associated with satellite fragmentation requires comprehensive understanding of the dynamics involved. LÄS MER

  3. 2. Moving in the dark : Mathematics of complex pedestrian flows

    Magister-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Meghashyam Veluvali; [2023]
    Nyckelord :Mathematical modelling of pedestrian dynamics; stochastic systems; evacuation time; random walk method; parabolic equation; finite difference method;

    Sammanfattning : The field of mathematical modelling for pedestrian dynamics has attracted significant scientific attention, with various models proposed from perspectives such as kinetic theory, statistical mechanics, game theory and partial differential equations. Often such investigations are seen as being a part of a new branch of study in the domain of applied physics, called sociophysics. LÄS MER

  4. 3. ASSESMENT OF WIND POWER FORECASTING ERROR FOR GOTLAND

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Simon Rengmyr; [2022]
    Nyckelord :Wind power forecasting; Machine learning; Numerical weather prediction;

    Sammanfattning : When the wind blows and wind turbine generators harvests the kinetic energy and trans- forms it to electrical power, there is a need for predicting how much power that will be dispatched from the turbines. Even the most perfect computer model with high computa- tional power could not model the beauty of the forces of nature and we must accept some degree of forecasting error in the predicted power output due to the inherently stochastic patterns in the atmosphere.

  5. 4. Rocket Jet Impinging on a Surface

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Javier Capel Jorquera; [2022]
    Nyckelord :Rocket jet impinging on a surface; Favre-Averaged Equations; turbulence modeling; numerical considerations; Method of Characteristics; MOC; plate optimization;

    Sammanfattning : With the continuous growth of the space industry and the introduction of reusable rockets, the number of rocket launches is expected to increase significantly in the following years. During rocket launching, the engine exhaust impinges on the launch structure producing a complex flow field. LÄS MER

  7. 5. Rysk legitimering inför den ukrainska invasionen 2022

    Uppsats för yrkesexamina på grundnivå, Försvarshögskolan

    Författare :Niklas Klingborg; [2022]
    Nyckelord :Makt; legitimering; Ryssland; Ukraina; tematisk innehållsanalys; innehållsanalys; retorik; Nye; Welsh; Goddard; Krebs;

    Sammanfattning : Conflicts should be analyzed in terms of a full spectrum conflict including discourse. There are more means to achieve an end goal than through the kinetic force such as military means. The invasion of Ukraine 24th of February 2022 was the culmination of many years of soft and hard power practiced by the Russian state. LÄS MER
