  4. 2. Railway tread braking temperatures - Numerical simulation and experimental studies

    Author : Shahab Teimourimanesh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway tread braking; finite element analysis; railway wheels; rail chill; hot spots; frictional heating; heat partitioning; metro; field experiment; rig experiment;

    Abstract : Tread (block) braking is still one of the most common braking systems on railway vehicles. The action is carried out by pressing brake blocks against the tread of a wheel, which is also in rolling contact with the rail. READ MORE

    Abstract : Tread (block) braking is still one of the most common braking systems on railway vehicles.The action is carried out by pressing brake blocks against the tread of a wheel, which is also inrolling contact with the rail. READ MORE

  6. 4. Sensor Fusion for Smartphone-based Vehicle Telematics

    Author : Johan Wahlström; Peter Händel; Erik Gudmundson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The fields of navigation and motion inference have rapidly been transformed by advances in computing, connectivity, and sensor design. As a result, unprecedented amounts of data are today being collected by cheap and small navigation sensors residing in our surroundings. READ MORE

  7. 5. Joint Positioning and Multipath Radio Channel Estimation and Prediction

    Author : Anders Mannesson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis investigates the topic of joint positioning and radio channel estimation and prediction. Both positioning and radio channel estimation have a long history of research with many publications but the combination of the two has so far at large been left unexplored. READ MORE
