  2. 1. Multi-unit common value auctions : theory and experiments

    Author : Joakim Ahlberg; Lars Hultkrantz; Jan-Eric Nilsson; Jerker Holm; Statens väg- och transportforskningsinstitut; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Multi-Unit Auction; Common Value Auction; Laboratory Experiment; Game Theory; Economics; Q Economics; Q Economics; Economics;

    Abstract : Research on auctions that involve more than one identical item for sale was,almost non-existing in the 90’s, but has since then been getting increasing attention. External incentives for this research have come from the US spectrum, sales, the European 3G mobile-phone auctions,  and Internet auctions. READ MORE

  4. 2. A model of contextual factors and inter-organizational integration : A Ground Theory study of two supply chains

    Author : Hana Hulthén; Dag Näslund; Helena Forslund; Teknisk logistik; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inter-organizational integration; contingency theory; grounded theory; contextual factors; Logistics; Logistik; Logistics; Logistik; supply chain integration; inter-organizational integration; structural contingency theory; grounded theory; contextual factors; fit;

    Abstract : The purpose of this thesis is to contribute to understanding of the effect of organizational context on supply chain integration. One result is a context- based model that can provide support for practitioners regarding what level of integration to establish with suppliers and customers. READ MORE

  5. 3. Vacua in String Theory : de Sitter Space and Stability in Flux Compactifications

    Author : Sergio C. Vargas; Ulf Danielsson; Alessandro Tomasiello; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; String theory; Cosmology; Flux Compactifications; Landscape; Swampland;

    Abstract : Our understanding of cosmology has evolved radically in the last decades. Current models demand the presence of dark energy in our universe and the most favored candidate behind this component is a small positive cosmological constant that characterizes a de Sitter (dS) spacetime.

  6. 4. Linear response theory : from black hole thermalization to Weyl semimetals

    Author : Jorge Laraña Aragón; Bo Sundborg; Edwin Langman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Abstract : Linear response theory is an incredibly powerful calculation tool. We apply this framework in quantum field theory to a variety of models originated from distinct areas in theoretical physics and for different reasons. READ MORE

  7. 5. Characterization of energy gases by ultrasound : theory and experiments

    Author : Pär-Erik Martinsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : The long-term goal with the research presented in this thesis has been to develop an ultrasonic sensor capable of measuring the energy content of energy gases such as natural- and biogas. The energy content can be calculated if the concentration of each constituent of a gas mixture is known. READ MORE
