1. 1. Adaptive Finite Element Methods for Optimal Control Problems

   Författare :Karin Kraft; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dual weighted residual; adaptive; Newton method; variational inequality; vehicle dynamics.; multilevel algorithm; discontinuous Galerkin method; a posteriori error estimate; finite element method; optimal control; control constraint;

   Sammanfattning : In this thesis we study the numerical solution of optimal control problems. The problems considered consist of a systemof differential equations, the state equations, which are governed bya control variable. The goal is to determine the states and controls which minimize a given cost functional. LÄS MER

4. 3. Indirect System Identification for Unknown Input Problems : With Applications to Ships

   Författare :Jonas Linder; Martin Enqvist; Fredrik Gustafsson; Alexandre Sanfelice Bazanella; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Model structure; Unknown inputs; Indirect input measurements; Physical models; Instrumental variable; Closed loop; Graybox model; Identifiability; Ship; Marine vessel; Operational safety; Inertial measurement unit;

   Sammanfattning : System identification is used in engineering sciences to build mathematical models from data. A common issue in system identification problems is that the true inputs to the system are not fully known. In this thesis, existing approaches to unknown input problems are classified and some of their properties are analyzed. LÄS MER

5. 4. Influences, effects and changes from interventions by eco-labelling schemes - What a Swan can do?

   Författare :Åke Thidell; Internationella miljöinstitutet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Direct effect; Eco-labelling; Intervention theory; Environmental labelling; Nordic Swan; Measurement method; Indirect effect;

   Sammanfattning : Eco-labelling is a voluntary and informative policy instrument aiming at stimulating environmentally beneficial product development through using the market forces. The Nordic Swan eco-labelling scheme has been in operation since 1989. LÄS MER

7. 5. The Duke of Uncertainty -Aspects of Professional Skill

   Författare :Lotte Alsterdal; KTH; []
   Nyckelord :practical versus theoretical knowledge; skill of epistemology; tacit knowledge; comparative case study; literarary metaphor; analogical thinking; indirect method; occupational training.;

   Sammanfattning : The Duke of Uncertainty - Aspects of Professional Skillis a dissertation whose title is a literary metaphor designedto draw attention to encounters with unforeseen problems anddilemmas at work.The first part of the dissertation presents the skill andtechnology tradition that has developed over the last twentyyears through explorative case studies.
