  2. 1. Effect of Hyporheic Exchange on Conservative and Reactive Solute Transport in Streams : Model Assessments Based on Tracer Tests

    Author : Karin Jonsson; Anders Wörman; Bernhard H. Schmid; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; conservative; hyporheic exchange; model; reactive; retention; solute; sorption kinetics; stream transport; temporal moments; tracer experiment; Geovetenskap; Earth sciences; Geovetenskap; Sedimentology; sedimentologi;

    Abstract : Understanding of the processes affecting solute transport in flowing water is important for the possibility to predict the evolution with time of polluted stream systems. This thesis presents tracer experiment methodology and model developments for solute transport in streams, with special focus on retention processes and their effect on solute stream transport.

  4. 2. Molecular Exchange in Colloidal Dispersions

    Author : Alex Evilevitch; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; charged micoremulsion droplets; kinetics; mechanism.; Physical chemistry; Fysikalisk kemi; molecular transport; cell model; infinite dilution limit; turbidity measurements; oil solubilization; computer simulation; modeling; monomer diffusion; molecular exchange; Microemulsion droplets; oil droplets;

    Abstract : This thesis is a study of molecular exchange between the aggregates in a colloidal dispersion. The problem of oil molecular transport at resolubilization of big oil drops by smaller microemulsion droplets is considered as an experimental model system. READ MORE

  5. 3. Model and tool integration in high level design of embedded systems

    Author : Jianlin Shi; Martin Törngren; Johan Lilius; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model integration; Model transformation; Tool integration; Model based development; Embedded Systems; Engineering mechanics; Teknisk mekanik;

    Abstract : The development of advanced embedded systems requires a systematic approach as well as advanced tool support in dealing with their increasing complexity. This complexity is due to the increasing functionality that is implemented in embedded systems and stringent (and conflicting) requirements placed upon such systems from various stakeholders.

  6. 4. Change and exchange : electronic document management in building design

    Author : Kurt Löwnertz; KTH; []
    Keywords : ;

    Abstract : Producing documents using computer supported methods hasbecome common practice in the construction industry, but themanagement of documents is still to a large degree done withmanual methods. Some pioneering users in design, constructionand facility management respectively have applied electronicdocument management (EDM) within their organisations or forprojects. READ MORE

  7. 5. Model and Reality : Connecting BIM and the Built Environment

    Author : Gustaf Uggla; Milan Horemuz; Patric Jansson; Väino Tarandi; Alojz Kopáčik; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geodesi; Geodesy;

    Abstract : The adoption of building information modeling (BIM) in the architecture, engineering, and construction (AEC) industry is changing the way informa-tion regarding the built environment is created, stored, and exchanged. In short, documents are replaced with databases, processes are automated, and timelines become more circular with an emphasis on managing the life cycles of all manufactured objects. READ MORE
