  2. 1. Linear Model Predictive Control : Stability and Robustness

    Author : Johan Löfberg; Lennart Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Most real systems are subjected to constraints, both on the available control effort and the controlled variables. Classical linear feedback is in some cases not enough for such systems. This has motivated the development of a more complicated, nonlinear controller, called model predictive control, MPC.

  5. 3. Osteoarthritis of the Hip and Uncemented Total Hip Arthroplasty : Effects of Immediate Weight Bearing on Implant Stability, Bone Mineral Density, and Body Composition

    Author : Olof Wolf; Hans Mallmin; Sune Larsson; Jan Milbrink; Per Mattsson; Per Adolphson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoarthritis of the hip; uncemented; total hip arthroplasty; stability; RSA; BMD; DXA; body composition; weight bearing; Orthopaedics; Ortopedi; Orthopaedics; Ortopedi;

    Abstract : The initial recommendation for the postoperative regime after uncemented total hip arthroplasty (THA) was 6-12 weeks of partial weight bearing (PWB) to obtain a stable implant position during bone ingrowth. In recent years patients with uncemented THA have increasingly practiced full weight bearing (FWB) after surgery, which has largely been based on clinical experience rather than on scientific evidence.

  6. 4. Driving stability of passenger vehicles under crosswinds

    Author : Adam Brandt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crosswind; high speed; aerodynamics; driving stability; vehicle dynamics;

    Abstract : Passenger cars are a vital part of modern society, giving people the freedom of flexible travel. As technology advances, customers increase their demands for future products. The automotive industry must, therefore, adapt to society's requirements of energy-efficient travel, where developing low drag vehicles is key. READ MORE

  7. 5. On bone quality and implant stability measurements

    Author : Bertil Friberg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; early failures; titanium implants; jaw bone quality; jaw bone volume; cutting torque; implant stability; resonance frequency; one-stage surgery;

    Abstract : In conjuction with placement of oral implants, the jaw bone quality assessment is mainly based on quantitative radiographic measures and the subjective opinion of the performing surgeon. While the primary implant stability is discussed in terms of the pre-set motor torque and the subjective hand-felt perception during final tightening of implants, the secondary stability is defined as the absence of implant mobility.
