  1. 16. Automated Verification and Generation of Flexible Automation Control

    Författare :Johan Richardsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; manufacturing systems; program generation; control; verification;

    Sammanfattning : Consumer product life-cycles are constantly shortening; the automotive industry is an illustrative example. As a consequence, the introduction of new products into the manufacturing system necessarily becomes more frequent. Inherently, this brings a performance reduction for the manufacturing system.

  3. 17. Calibration and Modelling of Adipose Tissue Under Impact Loading

    Författare :Hosein Naseri; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Constitutive modelling; Global sensitivity analysis; Adipose tissue; Finite element human body models; Obesity;

    Sammanfattning : Vehicular injury is one of the main reasons for traumatic injuries. Finite Element HumanBody Models (FEHBM) have become very popular to assess car crashes and the subsequentinjuries. It provides the possibility to predict stress and strain values in tissue level byrepresenting anatomical structures in details. LÄS MER

  4. 18. Evaluation of Variable Speed Limits : Empirical Evidence and Simulation Analysis of Stockholm’s Motorway Control System

    Författare :Albania Nissan; Haris N. Koutsopoulos; Tomer Toledo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorway Control System; Mainline Control; Variable Speed Limits; Driver Behavior; Capacity; Intelligent Transport Systems; microsimulation model; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Mechanical energy engineering; Mekanisk energiteknik; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : Variable Speed Limits (VSL) are often used to improve traffic conditions on congested motorways. VSL can be implemented as mandatory or advisory. The objective of the thesis isto study in detail the effectiveness of VSL. The focus is on both, design parameters and conditions under which VSL are most effective. LÄS MER

  5. 19. Direct Fourier methods in 3D-reconstruction from cone-beam data

    Författare :Caroline Axelsson; Michel Defrise; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The problem of 3D-reconstruction is encountered in both medical and industrial applications of X-ray tomography. It would seem natural to recover volume data by just repeating 2D-reconstructions slice-by-slice. LÄS MER

  7. 20. Electrostatic turbulence and electron heating in collisionless shocks

    Författare :Ahmad Lalti; Yuri V. Khotyaintsev; Hans Nilsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Sammanfattning : Collisionless shocks are one of the most peculiar phenomena in space where non-linear collective phenomena in the plasma dominate the dynamics. They are believed to be one of the most efficient particle accelerators in the universe, and have internal dynamics that are yet to be fully explored. LÄS MER
