  1. 1. 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.

  3. 2. Nonlinear Absorbing platinum(II) Acetylides for Optical Power Limiting Applications

    Författare :Robert Westlund; Eva Malmström; Sergei Vinogradov; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optical power limiting; Polymer chemistry; Polymerkemi;

    Sammanfattning : During the past few decades, laser technology has had a strong impact on our society, providing important contributions to materials processing, data storage, communications, medicine, and defense applications. However, the progress in laser technology has also brought about the development of harmful portable high‐power lasers and tactical laser weapons. LÄS MER

  4. 3. 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

  5. 4. E-government and e-governance : Swedish case studies with focus on the local level

    Författare :Irene Bernhard; Hans Westlund; Agneta Ranerup; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; governance; e-government; e-governance; New Public Management; municipal contact centres; planning; policy entrepreneurship; networks; implementation; translation; Sweden; Public administration; Political science;

    Sammanfattning : The concepts of e-government and e-governance are used interchangeably in most research and there is no single definition of these terms. The objective of this licentiate thesis is to provide a deeper understanding of these concepts through empirical studies in a Swedish context. LÄS MER

  7. 5. Perspektiv på platsmarknadsföring

    Författare :Elin Berglund; Hans Westlund; Stig Westerdahl; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Platsmarknadsföring; platsförsäljning; promotion; territoriell konkurrens; entreprenöriell politik; attraktivitet; samhällsplanering;

    Sammanfattning : The overarching aim of this study is to contribute with new perspectives on place marketing, theoretically as well as empirically. More specifically, the aim is to characterize the place marketing research literature, describe its content and explore the extent to which it is valid in a Swedish municipal context. LÄS MER
