  1. 1. Modelling E-scooterist Braking and Steering for Collision Avoidance

    Författare :Tianyou Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bicycles; Cycling safety; Active safety; Bicycle kinematics; E-scooters; Micromobility;

    Sammanfattning : Introduction: In the last few years, new road safety issues have emerged with the growing popularity of novel micromobility vehicles (MMVs). The term ‘novel MMV’ includes, in addition to electrically assisted bicycles, electric kick scooters (e-scooters) and Segway balance scooters (Segways)—which are usually distinct in appearance and operation from traditional MMVs (conventional bicycles).

  3. 2. Vehicle wakes subject to side wind conditions

    Författare :Magnus Urquhart; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drag; surrogate model; cavity; Latin Hypercube Sampling; wake; aerodynamics; real world conditions; Proper Orthogonal Decomposition; wind averaged drag; Radial Basis Functions; side wind; optimization; tapered extensions; cycle averaged;

    Sammanfattning : Passenger vehicles are associated with travel flexibility, today it is clear that this flexibility impacts the environment. Passenger vehicles account for more than one-tenth of all greenhouse gasses in Europe with approximately a quarter of the vehicle's energy consumption wasted as aerodynamic drag. LÄS MER

  4. 3. Electronic Structure Calculations of Point Defects in Semiconductors

    Författare :Andreas Höglund; Susanne Mirbt; Alison Mainwood; Uppsala universitet; []
    Nyckelord :Physics; electronic structure calculations; point defects; semiconductor; formation energy; equilibrium solubility limit; thermodynamic equilibrium concentration; transfer levels; negative-U; 110 surface; diffusion; activation energy; solar cells; Fysik;

    Sammanfattning : In this thesis point defects in semiconductors are studied by electronic structure calculations. Results are presented for the stability and equilibrium concentrations of native defects in GaP, InP, InAs, and InSb, for the entire range of doping conditions and stoichiometry. LÄS MER

  5. 4. Cryptic Female Choice and Male Mating Behaviour : Sexual Interactions in Beetles

    Författare :Martin Edvardsson; Göran Arnqvist; Paul Ward; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Cryptic female choice; Copulatory courtship; Harmful male traits; Nuptial gifts; Sperm competition; Sexual selection; Tribolium castaneum; Callosobruchus maculatus; Biologi; Biology; Biologi;

    Sammanfattning : The importance of cryptic female choice, i.e. female post-copulatory influence over male reproductive success, in driving the evolution of male traits remains controversial. The main aim of this thesis was to understand the post-copulatory consequences of sexual interactions and the importance of cryptic female choice in two species of beetle. LÄS MER

  7. 5. Future Assembly Information Systems - Redefining the Manufacturing Systems of Tomorrow

    Författare :Pierre Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manual assembly; Manufacturing systems; Industry 4.0; Assembly information systems;

    Sammanfattning : Product variety continues to increase as the manufacturing industry introduces customized products and services to address the varying demands of their customers. In the manufacturing industry, it is common for large and global manufacturing companies to grow through mergers and acquisitions. LÄS MER
