  1. 11. Mathematical modeling of electromagnetic disturbances in railway system

    Författare :Farid Monsefi; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance; Industrial Electronics; Industriell elektronik;

    Sammanfattning : By introduction of modern electronics into railway system, new challenges in understanding the electric and electromagnetic behavior of these systems arise. In this thesis, electromagnetic modeling of electric networks above dielectric and perfect electrically conducting surfaces are studied. LÄS MER

  3. 12. Semi-Automating Forestry Machines : Motion Planning, System Integration, and Human-Machine Interaction

    Författare :Simon Westerberg; Anton S. Shiriaev; Klas Nilsson; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forestry Robotics; Forest Machine Automation; Trajectory Planning; Hydraulic Manipulators; Teleoperation; Virtual Environments; Interaction Methods; Head Tracking;

    Sammanfattning : The process of forest harvesting is highly mechanized in most industrialized countries, with felling and processing of trees performed by technologically advanced forestry machines. However, the maneuvering of the vehicles through the forest as well as the control of the on-board hydraulic boom crane is currently performed through continuous manual operation. LÄS MER

  4. 13. Application of machine learning in systems biology

    Författare :Gang Li; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; uncertainty; Machine learning; genome-scale modelling; deep transfer learning; systems biology; regression;

    Sammanfattning : Biological systems are composed of a large number of molecular components. Understanding their behavior as a result of the interactions between the individual components is one of the aims of systems biology. LÄS MER

  5. 14. Characterization of sawlogs using industrial X-ray and 3D scanning

    Författare :Johan Skog; Olav Höjbö; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : In the Nordic countries, sawlogs are typically sorted upon arrival at the sawmill based on species and dimension. By processing batches of logs with similar size, the sawing process becomes more efficient; the need to change sawing pattern between individual logs is reduced, and the handling of sawn goods is simplified, since the number of different dimensions produced simultaneously decreases.

  7. 15. System Interconnection Design Trade-offs in Three-Dimensional (3-D) Integrated Circuits

    Författare :Roshan Weerasekera; Hannu Tenhunen; Li-Rong Zheng; Atila Alvandpour; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Interconnects; Parasitic Extraction; Repeaters; Signal Integrity; System-on-Chip SoP ; System-in-Package SiP ; System-on-Package SoP ; Three-dimensional 3-D Integration; Through-Silicon-Via TSV ; Vertical Integration; Information technology; Informationsteknik;

    Sammanfattning : Continued technology scaling together with the integration of disparate technologies in a single chip means that device performance continues to outstrip interconnect and packaging capabilities, and hence there exist many difficult engineering challenges, most notably in power management, noise isolation, and intra and inter-chip communication. Significant research effort spanning many decades has been expended on traditional VLSI integration technologies, encompassing process, circuit and architectural issues to tackle these problems.
