1. 6. Activation of dissolving pulps prior to viscose preparation

   Författare :Niklas Kvarnlöf; Ulf Germgård; Leif J. Jönsson; Carl-Axel Söderlund; Herbert Sixta; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dissolving pulp; enzyme; reactivity; viscose; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

   Sammanfattning : The conventional viscose manufacturing process is a mature process that needs to be improved with respect to its environmental impact and its production cost structure. Therefore a research study has been done with the aim to improve the reactivity of the dissolving pulp used, in order to reduce the chemical demand in the viscose process and thus reduce the cost and indirectly the environmental impact.

3. 7. Differential-algebraic equations and matrix-valued singular perturbation

   Författare :Henrik Tidefelt; Torkel Glad; Ulf Jönsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Differential-algebraic equations; uncertainty; singular perturbation; state estimation; Automatic control; Reglerteknik;

   Sammanfattning : With the arrival of modern component-based modeling tools for dynamic systems, the differential-algebraic equation form is increasing in popularity as it is general enough to handle the resulting models. However, if uncertainty is allowed in the equations — no matter how small — this thesis stresses that such equations generally become ill-posed. LÄS MER

5. 9. Essays on economic evaluation in health care : evaluation of hormone replacement therapy and uncertainty in economic evaluations

   Författare :Niklas Zethraeus; Handelshögskolan i Stockholm; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : This thesis contains six papers closely related to current research topics in the field of economic evaluation in health care. The thesis discusses methodological features of cost-effectiveness analysis (CEA) and cost-benefit analysis (CBA). It further relates to issues of modelling and how to account for uncertainty in economic evaluations. LÄS MER
