  4. 22. Analysis of Flow Structures in Wake Flows for Train Aerodynamics

    Author : Tomas W. Muld; Dan Henningson; Gunilla Efraimsson; Shia-Hui Peng; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Train Aerodynamics; Slipstream; Wake Flow; Detached-EddySimulation; Proper Orthogonal Decomposition; Koopman Mode Decomposi-tion; Surface-mounted Cube; Aerodynamic Train Model; Fluid mechanics; Strömningsmekanik; Vehicle engineering; Farkostteknik;

    Abstract : Train transportation is a vital part of the transportation system of today anddue to its safe and environmental friendly concept it will be even more impor-tant in the future. The speeds of trains have increased continuously and withhigher speeds the aerodynamic effects become even more important. READ MORE

  5. 23. Load Adapted Solar Thermal Combisystems - Optical Analysis and Systems Optimization

    Author : Svante Nordlander; Högskolan Dalarna; []
    Keywords : Solar Combisystems Concentrating Collector Optimization Incidence Angle Optical Efficiency Simulation TRNSYS Stagnation;

    Abstract : In a northern European climate a typical solar combisystem for a single family house normally saves between 10 and 30 % of the auxiliary energy needed for space heating and domestic water heating. It is considered uneconomical to dimension systems for higher energy savings. Overheating problems may also occur. READ MORE

  6. 24. Numerical Techniques for Acoustic Modelling and Design of Brass Wind Instruments

    Author : Daniel Noreland; Bertil Gustafsson; Leif Abrahamsson; Björn Sjögreen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acoustic horn; brass wind instrument; loudspeaker; optimization; hybrid method; Numerical Analysis; Numerisk analys;

    Abstract : Acoustic horns are used in musical instruments and loudspeakers in order to provide an impedance match between an acoustic source and the surrounding air. The aim of this study is to develop numerical tools for the analysis and optimisation of such horns, with respect to their input impedance spectra. READ MORE

  7. 25. Partial and General Equilibrium Effects of Unemployment Insurance : Identification, Estimation and Inference

    Author : Mathias von Buxhoeveden; Björn Öckert; Johan Vikström; Rafael Lalive; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Labor Economics; Unemployment Insurance; Wage Level and Structure; Job Search; Duration Analysis; Econometric and Statistical Methods; Selection Models; Economics; Nationalekonomi;

    Abstract : Essay I: Wage setting models typically posit a tight relationship between the generosity of unemployment insurance (UI) and equilibrium wages. This paper estimates the effect of UI on workers’ wages. READ MORE
