  1. 16. Flow field investigation of rotating wheels on passenger cars

    Författare :Christoffer Landström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The importance of aerodynamics of road-going vehicles on the total driving resistance and hence fuel consumption is well known to vehicle manufactures. At present, upper body aerodynamics of passenger cars is relatively well understood. LÄS MER

  3. 17. Semantic mapping using virtual sensors and fusion of aerial images with sensor data from a ground vehicle

    Författare :Martin Persson; Achim Lilienthal; Javier González; Örebro universitet; []
    Nyckelord :semantic mapping; aerial image; mobile robot; supervised learning; semi-supervised learning; TECHNOLOGY; TEKNIKVETENSKAP; Industriell mätteknik; Industrial Measurement Technology;

    Sammanfattning : In this thesis, semantic mapping is understood to be the process of putting a tag or label on objects or regions in a map. This label should be interpretable by and have a meaning for a human. The use of semantic information has several application areas in mobile robotics. LÄS MER

  4. 18. Multi-Echelon Inventory Control with Consideration of Emissions and Service Differentiation

    Författare :Lina Johansson; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : An increased focus on sustainability and initiatives towards green supply chains raises new challenges for efficient inventory control. This doctoral thesis addresses the consequences some of these initiatives have on the modelling of inventory systems and the resulting policy variables. LÄS MER

  5. 19. Communication acoustics in classroom environments : on the use of assistive listening devices

    Författare :Johan Odelius; John S. Bradley; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : Assistive listening devices (ALDs) are used in classrooms to assist communication for students with hearing loss. An ALD, a system of external microphones, transmits sound directly to the students' hearing aids. The signal is coupled to the hearing aid using a radio frequency (FM) or an induction loop (IL) system. LÄS MER
