    Abstract : Cerium dioxide, or ceria, is a chemically stable oxygen ion conducting material with a capacity to store and release oxygen, and is therefore extensively used in combustion catalysts. The Cu-Ce-O system has been identified as one of the most active catalysts for the combustion of carbon monoxide. READ MORE

  4. 2. Synthesis, Properties and Bonding in Hume-Rothery Transition-metal Gallides and Indides

    Author : Per Viklund; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Material technology; Kemi; Chemistry; Bonding; Structural stability; Electronic-structure; Neutron diffraction; X-ray diffraction; Atomic Structure; Intermetallics; Hume--Rothery; Materiallära; materialteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : In this work the intermetallic systems formed by transition-metals from group 5 to 9 with Ga, In and Zn have been experimentally and theoretically studied in detail. Syntheses, compositional analyses, X-ray and neutron diffraction (single crystal as well as powder) and measurements of physical properties, e.g. READ MORE

  5. 3. The Rhythm of Thinking: Immanence and Ethics in Theater Performance

    Author : Johan Petri; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; artistic research; co-composition; collective processes; compositional structure; dramaturgy; ethics; hierarchy in collective creation; immanent collective creation; instant collective composition; multiplicity; music theater; performance philosophy; performative critique; process ontology; process philosophy; relation of non-relation; theater; theater directing; theatrical composition; Rosi Braidotti; John Cage; Gilles Deleuze; Brian Massumi; Mathias Spahlinger;

    Abstract : The dissertation The Rhythm of Thinking: Immanence and Ethics in Theater Performance is an artistic research project in the field of theater, with directing and theatrical composition and dramaturgy as its main points of focus. The critical exploration is based on the experience of conceptualizing and directing three different theater performances. READ MORE

  6. 4. Magnetic Heterostructures : The Effect of Compositional Modulation on Magnetic Properties

    Author : Inna Soroka; Roger Wäppling; Björgvin Hjörvarsson; Rudolf Schäfer; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Magnetism; Sputter deposition; Superlattice; Multilayers; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : The effect of compositional modulation on structural and magnetic properties of magnetic heterostructures was explored. The systems under focus were ferromagnetic superlattices Fe81Ni19/Co, metal-insulator multilayers Al2O3/Ni81Fe19, nanoparticles and artificial multilayered pillars. READ MORE

  7. 5. On Compositional Approaches for Discrete Event Systems Verification and Synthesis

    Author : Sahar Mohajerani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Over the past decades, human dependability on technical devices has rapidly increased.Many activities of such devices can be described by sequences of events,where the occurrence of an event causes the system to go from one state to another.This is elegantly modelled by state machines.
