  1. 1. Livable and Sustainable Cities : Explorations of the City Soul and Energy-Efficient Housing based on Swedish Data on Citizens’ Preferences

    Författare :Marie Wahlström; Hans Westlund; Hans Lööf; Thomas Niedomysl; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attractive cities; place identity; green housing; urban planning; quantitative studies; residential satisfaction; Planering och beslutsanalys; Planning and Decision Analysis;

    Sammanfattning : Contemporary cities face many challenges, none the least from an urban planning perspective. Global climate change and urbanization is putting pressures on planning for combatting and adapting to, e.g., a warmer climate and an increased need for housing in already dense environments.

  3. 2. Kommunikationer, tillgänglighet, omvandling : en studie av samspelet mellan kommunikationsnät och näringsstruktur i Sveriges mellanstora städer 1850-1970

    Författare :Hans Westlund; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; urban history; transport history; infrastructure; structural change; communications network; accessibility; railways; regional development; Kommunikationer; Sverige; ekonomiska förhållanden; historia; 1800-talet; 1900-talet;

    Sammanfattning : This study deals with the relationship between communications networks and economic structure in medium-sized Swedish towns 1850-1970. Medium-sized towns have been defined as those which were ranked 4th-20th in terms of population at two points in time: in the year 1900, when industry had established a foothold and the most important railways had been built, and in the year 1970, at the end of the period studied.

  5. 4. Simplified models for emission formation in diesel engines during transient operation

    Författare :Anders Westlund; Hans-Erik Ångström; Martti Larmi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel engine; emission modeling; transient operation; NOx; Soot; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : The work presented in this thesis is the result of the KTH CICERO project “Dynamic Engine Performance” in which the main objective was to develop simple models foremission formation. The demand for such models is increasing, mainly due to the tightening emission legislation for diesel engines which has lead to more complex engines and thereby more laborious development and calibration processes.

  7. 5. Measuring and Predicting Transient Diesel Engine Emissions

    Författare :Anders Westlund; Hans-Erik Ångström; Rolf Egnell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emission modelling; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

    Sammanfattning :   Due to its impact on human health and the nature surrounding us, diesel engine emissions have been significantly reduced over the last two decades. This reduction has been enforced by the legislating organs around the world that gradually have made the manufacturers transform their engines to today’s complex high-tech products. LÄS MER
