  1. 1. Argument Differentiation. Soft constraints and data-driven models

    University dissertation from Göteborg : University of Gothenburg

    Author : Lilja Øvrelid; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; syntactic arguments; parsing; lexical acquisition; animacy; Scandinavian syntax; soft constraints; data-driven models; machine learning;

    Abstract : The ability to distinguish between different types of arguments is central to syntactic analysis, whether studied from a theoretical or computational point of view. This thesis investigates the influence and interaction of linguistic properties of syntactic arguments in argument differentiation. READ MORE

  2. 2. On soft-switching isolated AC/DC converters without auxiliary circuit

    University dissertation from Stockholm : KTH

    Author : Staffan Norrga; Stefan Östlund; Rik De Doncker; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical power technology; voltage source converter; cycloconverter; isolated converter; medium frequency transformer; soft switching; modulation; commutation; wind power; electric traction; Elkraftteknik; TECHNOLOGY Electrical engineering; electronics and photonics Electric power engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elkraftteknik;

    Abstract : The thesis is concerned with a class of power electronic converter systems that permit bidirectional AC/DC conversion with galvanic separation of the AC and DC sides by a transformer operating at elevated frequency. The systems consist of a capacitively snubbered voltage source converter and a cycloconverter, separated by the mentioned transformer. READ MORE

  3. 3. Essays on Incentives and Leadership

  4. 4. Sources of Dust Extinction in Type Ia Supernovae Measurements and constraints from X-rays to the Infrared

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Joel Johansson; Edvard Mörtsell; Ariel Goobar; Rahman Amanullah; Bruno Leibundgut; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supernovae; interstellar dust; circumstellar dust; cosmology; Physics; fysik;

    Abstract : The use of Type Ia supernovae (SNe Ia) as distance indicators is essential for studying the expansion history of the Universe and for exploring the nature of dark energy. However, a lack of understanding of the progenitor systems and the empirically derived colour-brightness corrections represent severe limitations for SNe Ia as cosmological probes. READ MORE

  5. 5. Fault Tolerance for Real-Time Systems: Analysis and Optimization of Roll-back Recovery with Checkpointing

    University dissertation from Lund University

    Author : Dimitar Nikolov; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft errors; fault tolerance; real-time systems; checkpointing; reliability;

    Abstract : Increasing soft error rates in recent semiconductor technologies enforce the usage of fault tolerance. While fault tolerance enables correct operation in the presence of soft errors, it usually introduces a time overhead. READ MORE
