  2. 1. Nitritation and denitritation in sludge liquor treatment

    Author : David Gustavsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nitritation; denitritation; nitrous oxide; nitric oxide; nitrogen dioxide; wastewater; sludge liquor;

    Abstract : Enhanced biological nitrogen removal at municipal wastewater treatment plants is a common procedure to prevent eutrophication in water bodies. Increased load, stricter effluent regulations, and demands for reduced resource and energy consumption present new challenges for the wastewater treatment plants. READ MORE

  4. 2. The Socialization of Intergroup Attitudes : The Problem of Generations

    Author : David Ekstam; Gina Gustavsson; Anders Westholm; Mikael Hjerm; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Socialization; intergroup attitudes; cohort analysis; generational replacement; age effects; Statskunskap; Political Science;

    Abstract : This doctoral thesis regards long-term aggregate trends in intergroup attitudes and the individual-level mechanisms that underlie change and continuity on the aggregate-level. The thesis focusses primarily on attitudes toward homosexuality in the North American context and attitudes toward immigration in the European context. READ MORE

  5. 3. Static Execution Time Analysis of Parallel Systems

    Author : Andreas Gustavsson; Björn Lisper; Jan Gustafsson; Andreas Ermedahl; David Broman; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; WCET analysis; parallel systems; multi-core; multicore; threaded programming language; Computer Science; datavetenskap;

    Abstract : The past trend of increasing processor throughput by increasing the clock frequency and the instruction level parallelism is no longer feasible due to extensive power consumption and heat dissipation. Therefore, the current trend in computer hardware design is to expose explicit parallelism to the software level. READ MORE

  6. 4. Treacherous Liberties : Isaiah Berlin's Theory of Positive and Negative Freedom in Contemporary Political Culture

    Author : Gina Gustavsson; Li Bennich-Björkman; Johan Tralau; Karl-Oskar Lindgren; David Miller; Uppsala universitet; []

    Abstract : Contemporary attitudes in affluent Western societies are characterised by a growing emphasis on individual freedom. What, then, does this commitment to liberty entail for our openness to diversity; and ultimately for liberal democracy? Previous research on popular attitudes, for example by Ronald Inglehart, tends to assume that valuing freedom entails an encouragement of a plurality of life-styles. READ MORE

  7. 5. Dynamic Modeling of Hydropower Generators

    Author : David Rondon; Jan-Olov Aidanpää; Rolf Gustavsson; Florian Thiery; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinkonstruktion; Machine Design;

    Abstract : Modeling the dynamics of hydropower generators has been the aim pursued by many studies, as providing a reliable model would lead to more cost-effective designs. Hydropower generators comprise many parts, tilting-pad bearings, shaft, rotor rim, and stator among them, that contribute to the system's nonlinearities. READ MORE
