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

   Author : Diala Jomaa; Mark Dougherty; Siril Yella; Högskolan Dalarna; []
   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

4. 2. The Optimal trigger speed of vehicle activated signs

   Author : Diala Jomaa; Högskolan Dalarna; []
   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

5. 3. Assessing Distributional Properties of High-Dimensional Data

   Author : Rashid Mansoor; Holgersson Thomas; Ghazi Shukur; Helgi Tomason; Jönköping University; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : This doctoral thesis consists of five papers in the field of multivariate statistical analysis of high-dimensional data. Because of the wide application and methodological scope, the individual papers in the thesis necessarily target a number of different statistical issues. READ MORE

6. 4. The dynamics in harvested populations

   Author : Anders Wikström; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluctuations; temporal; state-space; Harvest; cod; vendace; elasticity; stage-structured; stochastic; growth-rate; Baltic Sea; Bothnian Bay;

   Abstract : We are interested in the effect of harvesting on population fluctuations and for that purpose we develop and analyze an age-structured model where recruitment is a stochastic process and the adult segment of the population is harvested. When a constant annual harvest is taken the coefficient of variation of the adult population increases for most parameter values due to the age truncation effect, i. READ MORE

7. 5. In-cylinder Flow Characterisation of Heavy Duty Diesel Engines Using Combustion Image Velocimetry

   Author : Henrik Dembinski; Hans-Erik Ångström; Werner Hentschel; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : In-cylinder flow in diesel engines has a large impact on combustion and emission formation. In this work, the flow is characterised with a new measurement method called combustion image velocimetry (CIV). READ MORE
