  1. 16. Exploring the intersection of design, reflection and sustainable food shopping practices : The case of the EcoPanel

    Författare :Ulrica Bohné; Cecilia Katzeff; Minna Räsänen; Teo Enlund; Pelle Ehn; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Design; reflection; sustainable food shopping practices; social practice theory; research through design; web application prototype; Människa-datorinteraktion; Human-computer Interaction;

    Sammanfattning : Food production has been shown to have considerable negative impacts on the environment. A means to reduce this is to choose organic products when shopping for food. LÄS MER

  3. 17. Stochastic Epidemic Models : Different Aspects of Heterogeneity

    Författare :Mathias Lindholm; Tom Britton; Maria Deijfen; Gianpaolo Scalia Tomba; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Sammanfattning : This thesis is concerned with the study of stochastic epidemic models for infectious diseases in heterogeneous populations. All diseases treated are of SIR type, i.e. individuals are either Susceptible, Infectious or Recovered (and immune). LÄS MER

  4. 18. Inverse problems in signal processing : Functional optimization, parameter estimation and machine learning

    Författare :Pol del Aguila Pla; Joakim Jaldén; Yonina C. Eldar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse problems; signal processing; machine learning; biomedical imaging; optimization; proximal optimization; regularization; mathematical modeling; identifiability; likelihood; logconcavity; immunoassays; convolutional coding; functional analysis; abstract inference; learned iterations; unrolled algorithms; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Inverse problems arise in any scientific endeavor. Indeed, it is seldom the case that our senses or basic instruments, i.e., the data, provide the answer we seek. LÄS MER

  5. 19. Geometrical and percolative properties of spatially correlated models

    Författare :Olof Elias; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; continuum percolation; brownian excursions; brownian interlacements; poisson cylinder model; fractal percolation;

    Sammanfattning : This thesis consists of four papers dealing with phase transitions in various models of continuum percolation. These models exhibit complicated dependencies and are generated by different Poisson processes. For each such process there is a parameter, known as the intensity, governing its behavior. LÄS MER

  7. 20. Stochastic epidemics on random networks and competition in growth

    Författare :Carolina Fransson; Pieter Trapman; Daniel Ahlberg; Julia Komjathy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; random graphs; branching processes; SIR epidemics; malthusian parameter; urn model; matematisk statistik; Mathematical Statistics;

    Sammanfattning : The COVID-19 pandemic has dramatically demonstrated the importance of epidemic models in understanding and predicting disease spread and in assessing the effectiveness of interventions. The overarching topic of this thesis is stochastic epidemic modelling, with the main focus on the role of the underlying social structure in infectious disease spread. LÄS MER
