  1. 16. Sociotechnical Knowledge. An Operationalised Approach to Localised Infrastructure Planning and Sustainable Urban Development

    Författare :Jaan-Henrik Kain; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process; critical realism; sociotechnical; strategic choice approach; sustainable development; practice; action; social construction; decision-making; capital; implementation; infrastructure; urban; actor network theory; local; systems theory; design; partnerships; planning;

    Sammanfattning : In processes of urban infrastructural reconfiguration, there is a counterproductive tension between tendencies of de-monopolisation and market liberalisation, on the one hand, and ambitions for sustainable urban development, drawing on Keynesian reformism and ecological modernisation, on the other. In this thesis, the aim is to overcome this tension and to facilitate a concrete operationalisation of the notion &'sustainable urban development' within concrete and localised processes of planning, design, decision-making and implementation.

  3. 17. On the Relations between Driving Patterns, Exhaust Emissions and Network Characteristics in Urban Driving

    Författare :Lena Smidfelt-Rosqvist; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic calming; intersections; driving adaptation; speed limits; Road transport technology; driving behaviour; Vägtransportteknik; overall effects; trip-long; non-local effects;

    Sammanfattning : The planning and design of street networks in cities influence driving behaviour and give rise to variations in driving patterns (i.e., speed and acceleration profiles) that affect exhaust emissions and fuel consumption. LÄS MER

  4. 18. Development of a non-destructive testing method for thermal assessment of a district heating network

    Författare :Peter Lidén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shutdown; NDT; Copper wires; Cooling method; District heating pipes; Polyurethane;

    Sammanfattning : This thesis presents the development of a non-destructive testing (NDT)method for thermal assessment of pre-insulated district heating (DH) pipes with high accuracy, in which the development process from literature review to its present stage is presented and discussed. Pre-insulated DH pipes have been in use for more than 40 years. LÄS MER

  5. 19. Enhancing Censorship Resistance in the Tor Anonymity Network

    Författare :Philipp Winter; Stefan Lindskog; Simone Fischer-Hübner; Steven Murdoch; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tor; censorship; anonymity; network; Computer Science; Datavetenskap;

    Sammanfattning : BaksidestextThe Tor network was originally designed as low-latency anonymity network.However, as the years progressed, Tor earned a reputation as also being a useful tool to circumvent Internet censorship. At times, the network counted 30,000 users only from China. LÄS MER

  7. 20. Automated Gravel Road Condition Assessment : A Case Study of Assessing Loose Gravel using Audio Data

    Författare :Nausheen Saeed; Moudud Alam; Roger G. Nyberg; Diala Jomaa; Mirka Kans; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Gravel roads; road maintenance; convolutional neural network CNN ; SVM; decision trees; ensemble bagged trees; GoogLeNet; ResNet50; ResNet18; sound analysis;

    Sammanfattning : Gravel roads connect sparse populations and provide highways for agriculture and the transport of forest goods. Gravel roads are an economical choice where traffic volume is low. In Sweden, 21% of all public roads are state-owned gravel roads, covering over 20,200 km. LÄS MER
