  1. 31. Material metabolism of residential buildings in Sweden: Material intensity database, stocks and flows, and spatial analysis

    Författare :Paul Gontia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; clustering algorithms; single-family buildings; bottom-up modeling; residential buildings; human settlements; spatial analysis; multi-family buildings; material flow accounting; construction materials; material intensity database; material stock; urban stock; built environment; anthropogenic metabolism;

    Sammanfattning : Construction materials are used for the expansion and maintenance of the built environment. In the last century, construction material stock has increased globally 23-fold. LÄS MER

  3. 32. Computational modeling of polycrystals using gradient crystal plasticity

    Författare :Mikkel Grymer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel algorithms; crystal plasticity; dual mixed finite element method; gradient hardening; grain modeling;

    Sammanfattning : This thesis treats the modeling of grain size dependence inmicrostructure models of metals. It is shown how gradient hardening, in a thermodynamically consistent fashion, can be included into a crystal plasticity model, which is used as the constitutive model in each grain of the polycrystal.

  4. 33. Essays on Spatial Economies and Organization

    Författare :Marcus Sundberg; Lars Lundqvist; Geoffrey J.D. Hewings; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; spatial computable general equilibrium; monopolistic competition; dynamic; organization; new economic geography; fragmentation; production chains; vertical; horizontal; regional economics; trade.; Business and economics; Ekonomi; Economics; Nationalekonomi; Economic geography; Ekonomisk geografi;

    Sammanfattning : This thesis concerns both static and dynamic modeling in a spatial computable general equilibrium setting. First, we have applied a static framework for the assessment of economic impacts of the Öresund bridge. Secondly, we make an attempt to enhance the static framework through the introduction of economic dynamics. LÄS MER

  5. 34. Continuum modeling of particle flows in high shear granulation

    Författare :Per Abrahamsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High shear granulation; parameter study; resolution dependence; continuum modeling; kinetic theory of granular flow; granular flow;

    Sammanfattning : High shear granulation is an important process in the pharmaceutical industry. The aim of the process is to produce granules with specific properties, like size and hardness, from powder mixtures. The properties of the granules are determined by the flow field in the mixer.

  7. 35. Modeling rating curves from close-range remote sensing data : Application of laser and acoustic ranging instruments for capturing stream channel topography

    Författare :Norris Lam; Steve W. Lyon; Jason W. Kean; Ida Westerberg; Helle Skånes; James Brasington; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; laser scanning; acoustic Doppler current profiler; hydraulic modeling; rating curves; Sweden; Physical Geography; naturgeografi;

    Sammanfattning : A rating curve provides a functional relationship between water height (i.e. stage) and discharge at a specified cross-section in a river. Used in combination with a time series of stage, rating curves become one of the central components for generating continuous records of streamflow. LÄS MER
