  1. 1. The Optimal trigger speed of vehicle activated signs

    University dissertation from Borlänge : Dalarna University

    Author : Diala Jomaa; Högskolan Dalarna.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; optimal trigger speed; vehicle activated sign; vehicle mean speed; standard deviation; calibration; Doppler radar; driver behaviour; data analysis; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Abstract : The thesis aims to elaborate on the optimum trigger speed for Vehicle Activated Signs (VAS) and to study the effectiveness of VAS trigger speed on drivers’ behaviour. Vehicle activated signs (VAS) are speed warning signs that are activated by individual vehicle when the driver exceeds a speed threshold. READ MORE

  2. 2. A data driven approach for automating vehicle activated signs

    University dissertation from Borlänge : Dalarna University

    Author : Diala Jomaa; Högskolan Dalarna.; [2016]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Estimation of state and identification of complex modulus based on measurements om a bar traversed by waves

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lars Hillström; Uppsala universitet.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Wave; extensional; flexural; bar; rod; beam; elastic; viscoelastic; complex modulus; non-parametric; parametric; standard deviation; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Solid Mechanics; hållfasthetslära;

    Abstract : Estimation of state and identification of complex modulus based on measurements on non-uniform rods and beams have been studied theoretically and experimentally. Two principal cases were studied. In the first case, the material properties are fully known and the state at a section is to be estimated. READ MORE

  4. 4. Search for beyond Standard Model physics with high-pT leptons

    University dissertation from Lund University, Faculty of Science, Department of Physics

    Author : Oleksandr Viazlo; Lund University.; Lunds universitet.; [2017-01]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LHC; ATLAS; TRT; LUCID; Luminosity; Beyond Standard Model; Doubly Charged Higgs; Fysicumarkivet A:2017:Viazlo;

    Abstract : This thesis covers four different topics related to the physics analysis in the ATLAS experiment that uses proton-proton collisions data provided by the Large Hadron Collider. The first topic is focused on the numerical simulation of the Transition Radiation Tracker which is one of the ATLAS tracking detectors. READ MORE
