  1. 1. Segregation, Education and Space - a Case Study of Malmö

    Detta är en avhandling från Lund University

    Författare :Rickard Persson; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; typo-morphology; comprehensive planning; education; segregation; Bourdieu; Malmö;

    Sammanfattning : This dissertation takes its point of departure in two questions about segregation and its implications for architectural research. The first question is whether examining segregation in terms of education is a fruitful tool for analyzing segregation in general. LÄS MER

  2. 2. Tilting trains Enhanced benefits and strategies for less motion sickness

    Detta är en avhandling från Lund University

    Författare :Rickard Persson; Mats Berg; Björn Kufver; Simon Iwnicki; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; running time; ride comfort; motion sickness; tilt control; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik; Järnvägsgruppen - Gröna tåget; Järnvägsgruppen - Gröna tåget;

    Sammanfattning : Carbody tilting is today a mature and inexpensive technology that allows higher train speeds in horizontal curves, thus shortening travel time. This doctoral thesis considers several subjects important for improving the competitiveness of tilting trains compared to non-tilting ones. LÄS MER

  3. 3. Tilting trains Technology, benefits and motion sickness

    Detta är en avhandling från Stockholm : KTH

    Författare :Rickard Persson; Evert Andersson; Karl Kottenhoff; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; motion sickness; ride comfort; running time; track geometry; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Sammanfattning : Carbody tilting is today a mature and inexpensive technology allowing higher speeds in curves and thus reduced travel time. The technology is accepted by most train operators, but a limited set of issues still holding back the full potential of tilting trains. LÄS MER

  4. 4. Surface reactions on mineral particles controlling the hydrolysis of glucose phosphates

    Detta är en avhandling från Umeå : Kemiska institutionen, Umeå universitet

    Författare :Rickard Olsson; Per Persson; Reiner Giesler; Dean L. Hesterberg; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE Chemistry; MEDICIN Kemi;

    Sammanfattning : Phosphorus (P) is an essential nutrient. A significant amount of soil P may be in the form of organophosphates. Due to the size of these compounds, hydrolysis is often required before P can be assimilated by organisms. Hydrolysis may be mediated by mineral surfaces, or catalyzed by extra cellular enzymes.

  5. 5. Science mapping and research evaluation a novel methodology for creating normalized citation indicators and estimating their stability

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Cristian Colliander; Rickard Danell; Olle Persson; Jesper Schneider; [2014]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; document-document similarity; science mapping; citation analysis; citation normalization; stability analysis; citation impact; research evaluation; library and information science; biblioteks- och informationsvetenskap;

    Sammanfattning : The purpose of this thesis is to contribute to the methodology at the intersection of relational and evaluative bibliometrics. Experimental investigations are presented that address the question of how we can most successfully produce estimates of the subject similarity between documents. LÄS MER
