  1. 1. Diskursanalys av autonoma vapensystem : Med Sverige i fokus

    Kandidat-uppsats, Umeå universitet/Statsvetenskapliga institutionen

    Författare :Ellen Andersson; [2022]
    Nyckelord :Autonomous weapons systems; discourse; Sweden; social constructivism; Foucault; Autonoma vapensystem; diskurs; Sverige; socialkonstruktivism; Foucault;

    Sammanfattning : Military developments suggest that autonomous weapons systems will be the future ofwarfare. Therefore, it is important to understand how to define the concept and how peopleexpress themselves around it. This paper will analyze how important actors in Sweden talkabout autonomous weapon systems. LÄS MER

  3. 2. Kernel density estimators as a tool for atmospheric dispersion models

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Daniel Egelrud; [2021]
    Nyckelord :Particle model; LPELLO; kernel density estimation; field of concentration; post-processing;

    Sammanfattning : Lagrangian particle models are useful for modelling pollutants in the atmosphere. They simulate the spread of pollutants by modelling trajectories of individual particles. However, to be useful, these models require a density estimate. The standard method to use has been boxcounting, but kernel density estimator (KDE) is an alternative. LÄS MER

  4. 3. Boundary conditions for modeling deposition in a stochastic Lagrangian particle model

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Tobias Jonsson; [2015]
    Nyckelord :Lagrangian dispersion model; Boundary behavior; time step;

    Sammanfattning : The Swedish defence agency (FOI) has developed a particle model (called Pello) that simulates the dispersion of aerosols and gases. At the boundaries, such as the ground, the particles can either reflect back into the domain (the atmosphere) or be absorbed. LÄS MER

  5. 4. Anomaly detection in videosurveillance feeds

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Jonas Nordlöf; [2015]
    Nyckelord :;

    Sammanfattning : Traditional passive surveillance is proving ineffective as the number of available cameras for an operator often exceeds the operators ability to monitor them. Furthermore, monitoring surveillance cameras requires a focus that operators can only uphold for a short amount of time. LÄS MER

  7. 5. Modeling and implementation of dense gas effects in a Lagrangian dispersion model

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Niklas Brännlund; [2015]
    Nyckelord :Dense gas; Lagrangian dispersion model; Langevin equation; Stochastic modeling; Accidental releases;

    Sammanfattning : The use of hazardous toxic substances is very common in the industrial sector. The substances are often stored in tanks in storage compartments or transported between industrial premises. In case of an accident involving these substances, severe harm can affect both population and the environment. LÄS MER
