  2. 21. Improvement Potential and Equalization Circuit Solutions for Multi-drop DRAM Memory Buses

    Author : Henrik Fredriksson; Christer Svensson; Georg Braun; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Equalization; High speed IO; memory capacity; multi-drop buses; communication capacity; ASIC design; Electronics; Elektronik;

    Abstract : Digital computers have changed human society in a profound way over the last 50 years. Key properties that contribute to the success of the computer are flexible programmability and fast access to large amounts of data and instructions. READ MORE

  4. 22. Integrated In-Wheel Motors for Low Power Traction Application

    Author : Prakashraj Kasinathan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric golf cart; integral-slot; force density; flux-linkage; traction motors; forklift trucks; direct-drive; electric wheelchairs power wheelchairs; low speed machines; fractional-slot;

    Abstract : This thesis is primarily concerned with the practical limits, imposed by magnetic saturation and thermal considerations, of the force density in low-speed permanent-magnet electric machines. The practical force density values obtainable in integral- and fractional-slot machines are determined. READ MORE

  5. 23. An Experimental Study on Melt Fragmentation, Oxidation and Steam Explosion during Fuel Coolant Interactions

    Author : Louis Manickam; Weimin Ma; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; severe accident; fuel coolant interactions; melt jet breakup; debris properties; steam explosion; oxidation; high-speed visualization; Physics; Fysik;

    Abstract : Nordic type boiling water reactors (BWRs) adopt reactor cavity flooding as a severe accident mitigation strategy (SAMS) to achieve core melt fragmentation and long-term cooling of decay heat generating core debris. The qualification of this SAMS needs to address two main severe accident issues: debris bed coolability and steam explosion. READ MORE

  6. 24. On Evaluation of Working Conditions aboard High-Performance Marine Craft

    Author : Pahansen de Alwis; Karl Garme; Anders Rosén; Joakim Dahlman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed marine craft; human factors integration; whole-body vibration; epidemiology; musculoskeletal pain; fatigue; höghastighetsfartyg; human factors; HFI; helkroppsvibrationer; epidemiologi; muskuloskeletal smärta; utmattning; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : High-Performance Marine Craft (HPMC) is a complex system confronted by the stochastic nature of the waves challenging the safety of life at sea. The personnel aboard these craft are vulnerable to detrimental conditions, in fact, limiting the system’s performance evoking the significance of the Human Factors Integration (HFI) in the design and operation of these craft.

  7. 25. Goodness-of-fit tests for some discrete multiplicative models with applications to road traffic accident analysis

    Author : Åke Svensson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The work presented in the thesis was initiated by some problems in the analysis of experiments concerning the effect of speed limits on the number of road traffic accidents. In order to do such an analysis realistic statistical models are required. READ MORE
