  3. 2. On Electrohydraulic Pressure Control for Power Steering Applications : Active Steering for Road Vehicles

    Författare :Alessandro Dell'Amico; Petter Krus; Massimo Milani; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis deals with the Electrohydraulic Power Steering system for road vehicles, using electronic pressure control valves. With an ever increasing demand for safer vehicles and fewer traffic accidents, steering-related active safety functions are becoming more common in modern vehicles. LÄS MER

  4. 3. Essays on Information and Conflicts of Interest in Stock Recommendations

    Författare :Erik Lidén; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Stock recommendations; Printed media; Price-pressure hypothesis; Information hypothesis; Journalists; Analysts; EMH; Initiations; Information asymmetry; Initial public offerings; Quiet period; Underwriter analysts.;

    Sammanfattning : This thesis brings together three separate empirical essays on the information and conflicts of interest in stock recommendations. The first essay analyzes stock-price reactions to recommendations published in printed Swedish media and also trading volumes at and around the publication day, bid/ask spreads, and the post-publication drift in recommended stocks for the period 1995-2000.

  5. 4. Accuracy of turbocharged SI-engine simulations

    Författare :Fredrik Westin; KTH; []
    Nyckelord :boosting; turbocharging; supercharging; modelling; simulation; turbine;

    Sammanfattning : This licentiate thesis deals mainly with modelling ofturbocharged SIengines. A model of a 4-cylinder engine was runin both steady state and transient conditions and the resultswere compared to measured data. Large differences betweenmeasurements and simulations were detected and the reasons forthis discrepancy were investigated. LÄS MER

  7. 5. Modeling and control of actuators and co-surge in turbocharged engines

    Författare :Andreas Thomasson; Lars Eriksson; Gianfranco Rizzo; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The torque response of the engine is important for the driving experience of a vehicle. In spark ignited engines, torque is proportional to the air flow into the cylinders. Controlling torque therefore implies controlling air flow. LÄS MER
