  1. 1. Maintenance related losses a study at the Swedish National Rail Administration

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mattias Holmgren; Luleå tekniska universitet.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : The global competition among companies has lead to higher demands of the production system. Quality has become an important factor for competition. Customer satisfaction depends upon the fulfillment of a number of quality parameters. Two important quality parameters are dependability and safety. READ MORE

  2. 2. Compensation of Losses in Foreign Subsidiaries within the EU : A Comparative Study of the Unilateral Loss-Compensation Mechanisms in Austria and Denmark

    University dissertation from Jönköping : JIBS

    Author : Anna Gerson; Högskolan i Jönköping.; [2009]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Losses; group taxation; loss relief; neutrality; single-entity approach; horizontal equity; ability to pay principle; double dip; arbitrary income shifting; permanent income shifting; LAW JURISPRUDENCE Financial law; RÄTTSVETENSKAP JURIDIK Finansrätt; LAW JURISPRUDENCE Other law European law; RÄTTSVETENSKAP JURIDIK Övrig rätt EU-rätt;

    Abstract : This study commences in the problems related to the restricted possibilities for cross-border groups to take losses incurred in foreign subsidiaries into account upon taxation. These difficulties lead to the situation where the overall tax burden of the group, seen as an economic unit, might exceed its economic capacity. READ MORE

  3. 3. Magnetic Leakage Fields and End Region Eddy Current Power Losses in Synchronous Generators

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Birger Marcusson; Uppsala universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; magnetic leakage fields; leakage flux; eddy currents; losses; synchronous generator; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : The conversion of mechanical energy to electrical energy is done mainly with synchronous generators. They are used in hydropower generators and nuclear plants that presently account for about 80% of the electric energy production in Sweden. READ MORE

  4. 4. Temperature and heat losses simulation in core and winding of a power transformer
