  2. 1. Transport theory and finite element methods for mesoscopic superconducting devices

    Author : Kevin Marc Seja; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; non-equilibrium superconductivity; finite element methods; unconventional superconductors; quasiclassical theory; transport theory;

    Abstract : At low temperatures, electrons in a superconductor exhibit pairing correlations that result in a macroscopic, phase-coherent ground state. This leads to peculiar electromagnetic properties such as the flow of dissipationless charge currents and expelling of external magnetic fields. READ MORE

  4. 2. Dynamic Modelling of Transit Operations and Passenger Decisions

    Author : Oded Cats; Haris Koutsopoulos; Tomer Toledo; Wilson Nigel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public Transport; Transit Operations; Simulation Model; Traffic Simulation; Route Choice; Dynamic Model; Assignment Model; Control; SRA - Transport; SRA - Transport;

    Abstract : Efficient and reliable public transport systems are fundamental in promoting green growth developments in metropolitan areas. A large range of Advanced Public Transport Systems (APTS) facilitates the design of real-time operations and demand management. READ MORE

  5. 3. Moisture and Chloride Transport in Concrete

    Author : Filip Nilenius; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiscale modelling; mass transport; coupled diffusion; statistical volume element; interfacial transition zone.; computational homogenization; mesoscale;

    Abstract : Material properties pertaining to the physical phenomena of mass transport in concrete are important for the durability of concrete structures, and they can ultimately be derived from material heterogeneities found at different subscales. On the mesoscale level, these heterogeneities are mainly characterized by the presence of embedded aggregates in the cement paste, together with cracks. READ MORE

  6. 4. Transport of Radionuclides and Colloid Through Quartz Sand Columns

    Author : Birgit Christiansen-Sätmark; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transport; radionuclides; Goethite column experiments; sorption; Quartz; colloid;

    Abstract : Studies of the transport of radionuclides in the geosphere are one of the main tasks for performance assessment of a nuclear waste repository. A possible enhanced transport path for the radionuclides is the formation and transport of non-depositing colloids with a high affinity for radionuclides. READ MORE

  7. 5. Plastidial phosphate transport in plants

    Author : Patrik Milton Karlsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; phosphate transport; thylakoid membrane; root plastid; photosynthesis; leaf size; starch metabolism; homology modeling; site-directed mutagenesis;

    Abstract : Phosphorus is an essential element for all living organisms and is central to the genetics and energetics of life. Inorganic phosphate (Pi) is recurrently involved in protein regulation and signal transduction but also in energy transfer as a component of the ATP-molecule. READ MORE
