  1. 1. Constellation Shaping in Optical Communication Systems

    Författare :Ali Mirani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coherent receiver; constellation shaping; multidimensional modulation format; optical communications; probabilistic shaping; geometric shaping;

    Sammanfattning : Exploiting the full-dimensional capacity of coherent optical communication systems is needed to overcome the increasing bandwidth demands of the future Internet. To achieve capacity, both coding and shaping gains are required, and they are, in principle, independent. LÄS MER

  3. 2. Shaping of Food Microstructures

    Författare :Lars Hamberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; food microstructure; flow; emulsion; carrageenan whey protein isolates; shaping; aggregate; gelatine; suspension; gel formation; particle; Fourier shape description; shape; shape measurements;

    Sammanfattning : Shape, the shaping process and the functionality of shape for food microstructure are the focus of this thesis. Shape is one of the parameters that influences the microstructure functionality; hence microstructure shape optimisation is an interesting task in the development of new functional materials and processes, especially for food, in which structure-related texture is an essential part of the product.

  4. 3. Multidimensional Constellation Shaping for Coherent Optical Communication Systems

    Författare :Ali Mirani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lattice-based constellations; geometric shaping; probabilistic shaping; multidimensional modulation format; Voronoi constellation; constellation shaping; optical communications; coherent receiver;

    Sammanfattning : To overcome the increasing demands for Internet traffic, exploiting the available degrees of freedom in optical communication systems is necessary. In this thesis, we study how constellation shaping can be achieved in various dimensions and how various shaping schemes affect the whole performance in real systems. LÄS MER

  5. 4. Market-Shaping as Meta-Strategy : A Strategy of Strategies

    Författare :Alexander Flaig; Mikael Ottosson; Aku Valtakoski; Besma Glaa; Suvi Nenonen; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Market-shaping; Market-shaping strategies; Integrated strategies; Markets; Systemic trategies; Meta-strategies; Marknadsformning; Marknadsformande strategier; Integrerade strategier; Marknader; Systemiska strategier; Metastrategier;

    Sammanfattning : Markets are increasingly perceived as malleable systems constituted by actors that endogenously generate and shape the market. This view extends the traditional market view beyond the buyer-seller dyad and encompasses both directly market-related actors such as companies, suppliers, and buyers but also nonmarket actors such as regulators, lobbyists, journalists, activists, and the wider public.

  7. 5. Att skapa framtid : En analys av interaktionen i studie- och yrkesvägledande samtal med unga i migration

    Författare :Åsa Sundelin; Boel Englund; Fredrik Hertzberg; Stefan Lund; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; career counselling; conversations; institutional talk; migration; upper secondary school; dialogicality; interaction; communicative projects; meaning-making; career choices; pedagogik; Education;

    Sammanfattning : This is an empirical study that aims to contribute to knowledge about the opportunities the career counselling conversation offers young migrants in shaping their future. Conversations play a central role in career counselling activities in Swedish schools; furthermore, the question of how the Swedish society promotes the inclusion of its immigrants has become an increasingly urgent issue.
