  1. 1. Adaption of Inertial Confinement Fusion Resultsto Spherical Plasma Expansion at Comets

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Viktor Sparrman; [2022]
    Nyckelord :Plasma; Inertial confinement fusion; comet; plasma expansion; Vlasov-Poisson; integral invariants; ergodicity;

    Sammanfattning : Recent missions to solar system comets, such as ESA's Rosetta mission, raise interest for models and descriptions of their plasma environment. The interaction with various space phenomena such as stellar wind make the construction of an analytical description difficult. LÄS MER

  3. 2. Integrability of Boltzmann's discontinuous gravitational system

    Master-uppsats, KTH/Fysik

    Författare :Frode Boman; [2021]
    Nyckelord :Theoretical physics; Mathematical physics; Integrability; Integrable system; Boltzmann; Ergodicity; Discontinuous system;

    Sammanfattning : A dynamical system originally invented by Boltzmann has had recent developments. The system consists of a particle in a gravitational potential with an added centrifugal force, which is subject to reflection against a wall that separates the system from the gravitational center.

  4. 3. A Spatially Explicit Agent-Based Model of Human-Resource Interaction on Easter Island

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Peter Steiglechner; [2020]
    Nyckelord :Agent-based modelling; applied mathematics; socio-economic modelling; Agentbaserad modellering; tillämpad matematik; socioekonomisk modellering;

    Sammanfattning : The history of Easter Island, with its cultural and ecological mysteries, has attracted the interests of archaeologists, anthropologists, ecologists, and economists alike. Despite the great scientific efforts, uncertainties in the available archaeological and palynological data leave a number of critical issues unsolved and open to debate. LÄS MER

  5. 4. Blir det sannolikt en snöfylld jul? : En statistisk prognos med hjälp av Markovkedjor

    Kandidat-uppsats, Karlstads universitet/Handelshögskolan (from 2013)

    Författare :Niklas Tyni; [2020]
    Nyckelord :;

    Sammanfattning : Syftet med denna uppsats var att med hjälp av Markovkedjor göra en statistisk prognos för ensnöfylld jul för tre svenska väderstationer. Datamängderna som ligger till grund förskattningarna av övergångssanolikheterna sorterades så endast perioden 17 december – 31december för varje år användes. LÄS MER

  7. 5. Back to a General Theory - An Essay in Persuasion

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Georg Meier; Petter Svärd; [2017]
    Nyckelord :Keynes; DSGE model; ergodicity; effective demand; tripartite economics;

    Sammanfattning : Many Western countries experience failing monetary policy after the 2008 financial crisis. The lack of alternatives to established rules, even when they appear to fail, motivates a close look at the economic ideas John Maynard Keynes developed in his crisis-ridden lifetime, to answer the question: What can Keynes' writings contribute to the contemporary macroeconomic discussion? We trace from the publication of the General Theory (1936) until our time how macroeconomics has narrowed down into theoretical consensus, elevating policy recommendations developed in moderate times to an exclusive status of optimality.
