  1. 21. Mass and Heat Transport in Dryer Fabrics - Experiments and Modelling

    Författare :Simon Smrtnik; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat transport; dryer fabric design; fabric parameters; mass transport; condensation;

    Sammanfattning : A dryer fabric is used in the multi-cylinder dryer in order to improve the runnability of the web and to establish proper contact between the web and the hot cylinder, thus improving the heat transport. The dryer fabric separates the hot and moist paper from the ambient drying air and significantly influences the mass and heat transport. LÄS MER

  3. 22. On Energy Efficient Mobile Hydraulic Systems : with Focus on Linear Actuation

    Författare :Kim Heybroek; Petter Krus; Jan-Ove Palmberg; Torben Ole Andersen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this dissertation, energy efficient hydraulic systems are studied. The research focuses on solutions for linear actuators in mobile applications, with emphasis on construction machines. Alongside the aspect of energy efficiency, the thesis deals with competing aspects in hydraulic system design found in the development of construction machines. LÄS MER

  4. 23. Cost Optimization of Volumetric Surveillance for Sky Monitoring : Towards Flying Object Detection and Positioning

    Författare :Hiba Alqaysi; Mattias O'Nils; Najeem Lawal; Faisal Qureshi; Fabio Poiesi; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; image processing; deep learning; YOLOv4; smart cameras;

    Sammanfattning : Unlike surface surveillance, volumetric monitoring deals with three-dimensional target space and moving objects within it. In sky monitoring, objects fly within outdoor and often remote volumes, such as wind farms and airport runways. Therefore, multiple cameras should be implemented to monitor these volumes and analyze flying activities. LÄS MER

  5. 24. Low Temperature Waste Heat Recovery in Internal Combustion Engines

    Författare :Vikram Singh; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low Temperature Waste Heat Recovery; Rankine cycle; Coolant Temperature; Working Fluids;

    Sammanfattning : Over the past few decades, the automotive industry has increasingly looked towards increasing the efficiency of the internal combustion engine to meet more stringent emission norms and as a measure to meet demands for improved air quality in cities. One method to improve the internal combustion engine efficiency is to recover some of the energy lost to the coolant and the exhaust using a secondary thermodynamic cycle such as an Organic Rankine Cycle.
