  1. 16. Advancements in stratified flows through simulation, experiment and open research software development

    Författare :Ashwin Vishnu Mohanan; Erik Lindborg; Pierre Augier; James J. Riley; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geophysical flows; shallow water wave turbulence; energy cascade; stratified turbulence; waves and vortices; open source software; geofysikaliska strömningar; vågturbulens i grunt vatten; energi- kaskad; stratifierad turbulens; vågor och virvlar; öppen mjukvara; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Two studies of two-dimensional models of flows influenced by stratification and stratification/rotation are carried out in order to investigate whether a two-dimensional model can reproduce a downscale energy cascade with an associated k − 5/3 wavenumber spectrum. Firstly, a series of highly resolved numerical simulations of the classical shallow water model is carried out. LÄS MER

  3. 17. Experiments on biofilm formation and growth in laminar flows

    Författare :Cornelius Wittig; Shervin Bagheri; Thomas Crouzier; Wouter van der Wijngaart; Eleonora Secchi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofilm; streamers; wall shear stress; OCT; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : The interaction between fluid dynamics and biofilm growth plays a key role in both medical and industrial applications. Biofilms, or bacteria that are embedded in a protective matrix of extracellular polymeric substances, settle on interfaces such as on implanted devices or ship hulls. LÄS MER

  4. 18. Spatial and temporal aspects of intense attosecond pulses for pump-probe experiments

    Författare :Hampus Wikmark; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultrafast lasers; ultrafast optics; attosecond pulses; pump-probe experiments; XUV light; XUV focusing; wavefront sensing; XUV optics; X-ray optics; Fysicumarkivet A:2019:Wikmark; ultrasnabba lasrar; attosekundspulser; pump-prob-experiment; XUV-ljus; vågfrontmätningar; XUV-optik; Röntgen-optik;

    Sammanfattning : Nuclear and electronic dynamics in atoms and molecules are the foundation of many physical processes and chemical reactions. Often, these dynamics take place on timescales so much shorter than those commonly encountered that they are called ultrafast. LÄS MER

  5. 19. Characterisation of organic substances in waste materials under alkaline conditions

    Författare :Ivars Pavasars; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Organic substances are important constituents of different types of inorganic waste in that they can strongly influence the chemical behaviour and environmental properties of the waste materials. Two alkaline waste-material systems containing organic constituents were investigated: a cementitious radioactive waste repository and residues of incinerated municipal solid waste. LÄS MER

  7. 20. Money, meanng, power : The global financial market and dexterous communication

    Författare :Erik Andersson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; money; globalisation; financial markets; phenomenology; subjectivity; economic interaction; dexterous meaning; institutions; discursive power; hegemony;

    Sammanfattning : This doctoral dissertation is a theoretical experiment. The aim is to put the social role of the global financial market in a different critical perspective. LÄS MER
