  2. 21. Data-driven Train Delay Prediction

    Author : Kah Yong Tiong; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine learning; Predictive models; Data-driven; Railways; Train Delays;

    Abstract : In Sweden, extensive use and the inherent heterogeneity of train traffic have significantly increased the sensitivity of the train system so that the delay of one train can easily propagate to others. Repeated experiences with train delays can lead passengers to perceive that railway transportation is unreliable. READ MORE

  4. 22. Modeling pavement performance based on data from the Swedish LTPP database : predicting cracking and rutting

    Author : Markus Svensson; Sigurdur Erlingsson; Helge Mork; Statens väg- och transportforskningsinstitut; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cracking; Rutting wheel ; Prediction; Calculation; Mathematical model; Flexible pavement; Performance; Sprickbildning; Spårbildning; Förutsägelser; Beräkning; Matematiska modeller; Flexibla överbyggnader; Prestanda; 32 Road: Pavement design; 32 Road: Pavement design;

    Abstract : The roads in our society are in a state of constant degradation. The reasons for this are many, and therefore constructed to have a certain lifetime before being reconstructed. To minimize the cost of maintaining the important transport road network high quality prediction models are needed. READ MORE

  5. 23. Simulation and Measurement of Wheel on Rail Fatigue and Wear

    Author : Babette Dirks; Mats Berg; Roger Enblom; Mark Burstow; KTH; []
    Keywords : multibody simulations; prediction; wear; RCF; wheel; rail; cracks; measurements; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : The life of railway wheels and rails has been decreasing in recent years. This is mainly caused by more traffic and running at higher vehicle speed. READ MORE

  6. 24. Football on mobile phones : algorithms, architectures and quality of experience in streaming video

    Author : Jiong Sun; Haibo Li; Fernando Pereira; Umeå universitet; []
    Keywords : Electrical engineering; Quality of Experience; Wyner-Ziv coding; Universal Multimedia Access; motion estimation; Dynamic Programming; traffic prediction; utility function; vibrotactile; Elektroteknik; elektronik och fotonik; Electronics; elektronik;

    Abstract : In this thesis we study algorithms and architectures that can provide a better Quality of Experience (QoE) for streaming video systems and services. With cases and examples taken from the application scenarios of football on mobile phones, we address the fundamental problems behind streaming video services. READ MORE

  7. 25. Dispersion and Transformation of Traffic Exhaust Particles in the Urban Atmosphere

    Author : Matthias Ketzel; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; condensation; deposition; dilution; particle size distribution; plume model; street canyon; traffic pollution; urban environment; turbulence; aerosol dynamics modelling; coagulation; Physics; Fysik; Fysicumarkivet A:2004:Ketzel;

    Abstract : Ultrafine particles, their sources and fate in the atmosphere are currently key issues in atmospheric research owing to concern about their effects on human health and global climate. Traffic emissions are a dominating source of ultrafine particles, especially in urban areas. READ MORE
