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

    Author : Rickard Persson; Institutionen för arkitektur och byggd miljö; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; typo-morphology; comprehensive planning; education; segregation; Bourdieu; Malmö;

    Abstract : 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. READ MORE

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

    Author : Rickard Persson; Mats Berg; Björn Kufver; Simon Iwnicki; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; running time; ride comfort; motion sickness; tilt control; Vehicle engineering; Farkostteknik; Järnvägsgruppen - Gröna tåget; Järnvägsgruppen - Gröna tåget;

    Abstract : 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. READ MORE

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

    Author : Rickard Persson; Evert Andersson; Karl Kottenhoff; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; motion sickness; ride comfort; running time; track geometry; Vehicle engineering; Farkostteknik;

    Abstract : 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. READ MORE

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

    Author : Rickard Olsson; Per Persson; Reiner Giesler; Dean L. Hesterberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry; Kemi;

    Abstract : 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.

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

    Author : Cristian Colliander; Rickard Danell; Olle Persson; Jesper Schneider; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE
