  1. 1. Clinical and experimental studies of bone substitutes and dental implants in compromised bone sites

    Författare :Amela Trbakovic; Andreas Thor; Patricia Hedenqvist; Christer Dahlin; Uppsala universitet; []
    Nyckelord :clinical follow-up; calcium phosphates; rabbit model; sinus lift; radius model; in vivo; bisphosphonates; narrow diameter implants; dental implants; Oral and Maxillofacial Surgery; Käkkirurgi;

    Sammanfattning : Background: With an ageing population, an increase of more challenging implant treatments is expected. In this thesis, we evaluate the outcome of two faster implant protocols, in patients with compromised alveolar bone. LÄS MER

  3. 2. Sensor Fusion for Automotive Applications

    Författare :Christian Lundquist; Fredrik Gustafsson; Thomas B. Schön; Uwe Hanebeck; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kalman filter; PHD filter; extended targets; tracking; sensor fusion; road model; single track model; bicycle model;

    Sammanfattning : Mapping stationary objects and tracking moving targets are essential for many autonomous functions in vehicles. In order to compute the map and track estimates, sensor measurements from radar, laser and camera are used together with the standard proprioceptive sensors present in a car. LÄS MER

  4. 3. Periulnar Injuries Associated with Distal Radius Fractures

    Författare :Johan Scheer; Adolfsson Lars; Magnus Tägil; Linköpings universitet; []
    Nyckelord :Triangular fibrocartilage complex; Distal radius fractures; Wrist injuries; Distal radioulnar joint; Ulnocarpal stability; MEDICINE; MEDICIN;

    Sammanfattning : Residual dysfunction after a fracture of the distal radius is most often mild but may give rise to significant impairment especially in the younger active population. The symptoms often manifest around the distal ulna when loading the hand or rotating the forearm. LÄS MER

  5. 4. Mathematical and Physical Simulations of BOF Converters

    Författare :Xiaobin Zhou; Mikael Ersson; Pär Jönsson; Hans-Jürgen Odenthal; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOF; physical model; mathematical model; mixing time; kinetic enregy; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : The purpose of this study is to develop mathematical models to explore the mixing and its related phenomena in converter bath. Specifically, first, a mathematical model of a physical model converter, which was scaled down to 1/6th of a 30 t vessel, was developed in this study. LÄS MER

  7. 5. Aspects of microstructural evolution in chromium steels in high temperature applications

    Författare :Åsa Gustafson; KTH; []
    Nyckelord :Cr-steels; nucleation; coarsening; model; DICTRA; precipitates; carbides; carbo-nitrides; MX; VN; M23C6; TiC; TEM; EFTEM; Curie-temperature;

    Sammanfattning : In this thesis 9-12 % Cr steels, used for high-temperaturecomponents in fossil-fired power plants are considered. Thecreep strength of thees steels depend on their microstructurethat consists of a matrix of tempered lath martensite withdensely distributed precipitates. LÄS MER
