  1. 1. At the Mountains of Modeling : Multiscale Simulations of Desalination by Capacitive Deionization

    Författare :Johan Nordstrand; Joydeep Dutta; Oscar Tjernberg; Maarten Biesheuvel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Capacitive Deionization; Desalination; Modeling; Multiscale; Simulation; Avsaltning; Kapacitiv Avjonisering; Modellering; Multiskala; Simulering; Material and Nano Physics; Material- och nanofysik; Physics; Fysik;

    Sammanfattning : More than 2 billion people are living in water-scarce areas. Meanwhile, there are enormous amounts of water in the salty oceans. Capacitive deionization (CDI) rises to the challenge with electrochemical cells for desalinating the water. As the CDI field expands, modeling becomes an increasingly important part of the development landscape. LÄS MER

  3. 2. Metal film growth on weakly-interacting substrates : Multiscale modeling

    Sammanfattning : Thin films are nanoscale layers of material used to functionalize surfaces or to serve as building blocks in more complex devices. In recent years, thin metal films have become vital for modern devices within, e.g. LÄS MER

  4. 3. State-Oriented Business Process Modeling : Principles, Theory and Practice

    Författare :Ilia Bider; KTH; []
    Nyckelord :business process; dynamical system; formal semantics; persistent action; law-based programming; business analysis; business modeling; object-oriented modeling; conceptual modeling; workflow;

    Sammanfattning : In the last 50 years, a considerable amount of research workhas been completed in the mathematical system theory and theoryof control. Implementation of the results from this researchinto practice has drastically decreased the production costs.Most production processes are highly automated, and the use ofrobots in industry is growing.

  7. 5. Modeling the Microstructure Evolution During and After Hot Working in Martensitic Steel

    Författare :Nima Safara Nosar; John Ågren; Göran Engberg; Hans-Olof Andrén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; Martensitic steel; Carbides; Carbide size distribution; Carbide volume fraction; Carbide shape factor; Modellering; Martensitiskt stål; karbider; karbidstorleksfördelning; karbidvolymfraktion; karbidformfaktor; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : In this study, the goal is to predict the microstructure evolution during and after the hot working of a martensitic stainless steel with 13% chromium using a physically-based model in the form of a MATLAB toolbox. This model is based on dislocation density theory and consists of coupled sets of evolution equations for dislocation, vacancies, recovery, recrystallization, and grain growth. LÄS MER
