  1. 6. Adaptive and model-based control in laminar boundary-layer flows

    Författare :Nicolò Fabbiane; Dan S. Henningson; Aimee S. Morgans; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flow control; Control theory; Optimal control; Adaptive control; Boundary-layer flow; Fluid dynamics; Plasma actuator; Surface hot-wire; Transition delay;

    Sammanfattning : In boundary-layer flows it is possible to reduce the friction drag by breaking the path from laminar to turbulent state. In low turbulence environments, the laminar-to-turbulent transition is dominated by local flow instabilities – Tollmien-Schlichting (TS) waves – that exponentially grows while being con- vected by the flow and, eventually, lead to transition.

    Sammanfattning : Transplantation is the only cure for end-stage organ failure. With the transplantation follows the need for continuous treatment with immunosuppressive agents for as long as the graft functions, which entails major side effects. Less toxic treatments are therefore in great demand. Preferably, the treatment should also be limited in time. LÄS MER

  5. 9. Towards multi-sensor monitoringand control of Directed Energy Deposition using a Laser Beam

    Författare :Agnieszka Kisielewicz; Fredrik Sikström; Barbara Previtali; Högskolan Väst; []

    Sammanfattning : Under senare år har omfattande insatser gjorts för att främja mer hållbara flygtransporter i Europa. De konventionella tillverkningsmetoderna som används inom flyg- och rymdindustrin kräver betydande mängder råmaterial, vars utvinning, bearbetning och användning har negativa miljöeffekter. LÄS MER
