  1. 1. Modeling and Model Reduction in Automotive Systems

    Författare :Oskar Nilsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive systems; Lambda sensor; Model reduction; Modeling; Engine air path;

    Sammanfattning : The current control design development process in automotive industry and elsewhere involves many expensive experiments and hand-tuning of control parameters. Model based control design is a promising approach to reduce costs and development time. In this process low complexity models are essential. LÄS MER

    Sammanfattning : The current control design development process in automotive industry and elsewhere involves many expensive experiments and hand-tuning of control parameters. Model based control design is a promising approach to reduce costs and development time. In this process low complexity models are essential and model reduction methods are very useful tools.

  4. 3. Vancomycin resistant enterococci in Swedish broilers : emergence, epidemiology and elimination

    Författare :Oskar Nilsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Vancomycin resistance enterococci (VRE) are an important cause of nosocomial infections. Presence of VRE in farm animals constitute a reservoir of resistance that can spread to humans via the food-chain and is due to extensive use of the growth promoter avoparcin conferring cross-resistance to vancomycin.

    Sammanfattning : När börjar ett arbete och när slutar det? Denna avhandlings formella början var hösten 2011, och den föregicks av en licentiatuppsats som påbörjades 2004. Det var alltså för 10 år sedan som de grundläggande frågorna formulerades och som detta kunskapsbyggande blev en del av min vardag. LÄS MER

  7. 5. The effects of markets, managers and peers on worker outcomes

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Labor Markets; Wages; School competition; Managers; Co-Workers; Fertility; Gender; Economics; Nationalekonomi; Economics; Nationalekonomi;

    Sammanfattning : Essay 1: This essay exploits the entry of private independent high schools in Sweden to examine how local school competition affects the wages and the mobility of teachers in a market with individual wage bargaining. Using rich matched employer-employee panel data covering all high school teachers over a period of 16 years, I show that the entry of private schools is associated with higher teacher salaries, including higher salaries for teachers in public schools.
