  4. 3. A data driven approach for automating vehicle activated signs

    Författare :Diala Jomaa; Mark Dougherty; Siril Yella; Högskolan Dalarna; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimal trigger speed; vehicle activated sign; mean speed; standard deviation; calibration; driver behaviour; data driven approach; automatic model; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Sammanfattning : Vehicle activated signs (VAS) display a warning message when drivers exceed a particular threshold. VAS are often installed on local roads to display a warning message depending on the speed of the approaching vehicles. VAS are usually powered by electricity; however, battery and solar powered VAS are also commonplace. LÄS MER

  5. 4. Voluntary Information Sharing, Retail Pricing and Firm Performance

    Författare :Charlie Lindgren; Siril Yella; Niklas Rudholm; Johan Håkansson; Christian Sandström; Högskolan Dalarna; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Voluntary information sharing; online retailing; e-commerce; price comparison websites; CSR; consumer search;

    Sammanfattning : Online information sharing by firms has created an unprecedented amount of data to analyze by researchers. While conclusions from research should be drawn with basis in sound theory, there has also emerged a need to supplement these theoretical considerations with advanced data collection, storage and analysis as well as reporting to decisionmakers.

  7. 5. Automating condition monitoring of vegetation on railway trackbeds and embankments

    Författare :Roger G. Nyberg; Narendra K. Gupta; Mark S. Dougherty; Siril Yella; David J. Murray-Smith; Alistair Armitage; Högskolan Dalarna; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Sammanfattning : Vegetation growing on railway trackbeds and embankments present potential problems. The presence of vegetation threatens the safety of personnel inspecting the railway infrastructure. In addition vegetation growth clogs the ballast and results in inadequate track drainage which in turn could lead to the collapse of the railway embankment. LÄS MER
