  2. 1. Learning physics with Controllable Worlds : Perspectives for examining and augmenting physics students' engagement with digital learning environments

    Author : Elias Euler; Bor Gregorcic; Cedric Linder; Michael C. Wittmann; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Controllable Worlds; digital learning environments; modeling; semi-formalisms; microworlds; social semiotics; conversation analysis; embodied cognition; disciplinary-relevant aspects; responsive teaching; variation theory; contrast; dimensions of variation; relevance structure; creativity; grounded theory; activity types; exploration; testing; engineering; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Abstract : In this thesis I present a collection of case studies involving small groups of participants using ‘Controllable Worlds’—i.e., a particular class of physics digital learning environment (DLE) including simulations, ‘microworlds,’ and educational games that provides users with control over manipulable virtual environments.

  4. 2. Modeling of Electron Cooling : Theory, Data and Applications

    Author : Karin Rathsman; Tord Johansson; Pia Thörngren; Dieter Prasuhn; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Electron cooling; Beam dynamics; Vlasov technique; Nonlinear damping; Monte Carlo simulations; Nuclear physics; Kärnfysik; Nuclear Physics; Kärnfysik;

    Abstract : The Vlasov technique is used to model the electron cooling force. Limitations of the applicability of the method is obtained by considering the perturbations of the electron plasma. READ MORE

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

    Author : Víctor Gervilla Palomar; Kostas Sarakinos; Georgios Almyras; Davide Giuseppe Sangiovanni; Michael Tringides; Linköpings universitet; []

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. Fusion Plasma Observations at JET with the TOFOR Neutron Spectrometer : Instrumental Challenges and Physics Results

    Author : Maria Gatu Johnson; Matthias Weiszflog; Luciano Bertalot; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Fusion; Plasma diagnostics; Neutron Spectrometry; TOFOR; JET; ITER; time-of-flight; plasma heating; Nuclear physics; Kärnfysik; Applied Nuclear Physics; Tillämpad kärnfysik;

    Abstract : The neutron spectrometer TOFOR was installed at JET in 2005 for high-rate observation of neutrons from reactions between two deuterium (D) ions. Neutron spectrometry as a fusion plasma diagnostic technique is invoked to obtain information about the velocity states of fusion fuel ions. READ MORE
