    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gravel road; condition assessment; conceptual modelling; condition classification; data acquisition; data-driven methods; field experiment; literature review; maintenance; visual assessment; Maskinteknik; Mechanical Engineering;

    Sammanfattning : Gravel roads are essential for economic development as they facilitate the movement of people, transportation of goods and services, and promote cultural and social development. They typically connect sparsely populated rural areas to urban centres, providing essential access for residents and entrepreneurs. LÄS MER

  4. 3. Failure Monitoring and Asset Condition Assessment in Water Supply Systems

    Författare :Dalius Misiunas; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; reglerteknik; robotteknik; Automatiska system; Water supply; failure; detection; monitoring; location; bursts; hydraulics; leakage; asset management; condition assessment; pipelines; pipe networks; Automation; control engineering; robotics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Sammanfattning : In this thesis, different aspects of failure management in urban water supply systems are discussed. As assets are getting older, the number of pipe failures is increasing and an efficient failure management strategy becomes important. LÄS MER

  5. 4. 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

  7. 5. Social anxiety disorder in children and adolescents : assessment, maintaining factors, and treatment

    Författare :Rio Cederlund; Lars-Göran Öst; Samantha Cartwright-Hatton; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social anxiety disorder; youth; behavior therapy; parent involvement; assessment; Psychology; psykologi;

    Sammanfattning : The present dissertation consists of three empirical studies on social anxiety disorder (SAD) in a sample of Swedish children and adolescents. Based on findings made in a large behavior treatment study, the thesis contributes to the field of research on childhood SAD by investigating a factor that maintains the disorder, ways to measure and screen for diagnosis, and the treatment of the disorder.
