The paper discusses the solution to the optimal adaptive control problem over an extended time horizon. This leads to a controller that have dual features, i.e., tt uses control actions as well as probing actions. The solution of the optimal dual control problem is intractable from a computational point of view. Approximations to obtain simpler suboptimal dual controllers are thus important. There
Popular Abstract in Swedish När folk frågat mig vad det är egentligen jag håller på med på labbet, brukar jag lite slarvigt svara att jag jobbar med blod. Jag tänkte här lite närmare gå igenom vad det är jag egentligen gjorde på labbet för Er som undrat. Jag har studerat ett protein i blodkoagulationen som heter faktor V (läs 5). För att man ska förstå varför detta protein är viktigt, måste man noThe homologous blood coagulation factors V (FV) and factor VIII (FVIII) are important at sites of vascular injury for the amplification of the clotting cascade. Activated FV (FVa) serves as a cofactor to the enzyme activated factor X (FXa) in the activation of prothrombin. This complex is called the prothrombinase complex. FVIII functions as a cofactor to the enzyme activated factor IX (FIXa) in t
The thesis presents studies on the processing technology and the characterization of nanometer-sized and low-dimensional structures in III-V semiconductors. Two major approaches are described: 1) the combination of aerosol technology and plasma etching for the fabrication of quantum dots (QDs) in InP-based materials and 2) the use of high-resolution electron beam lithography and plasma or wet che
The report describes and analysis the water and sewerage system in five European countries from a resource based view I denna rapport intresserar vi oss för begreppet ’uthållighet’ (sustainability) inom ramen för vatten- och avloppsverksamheter. Utgångspunkten är emellertid varken teknisk eller ekologisk utan denna studie görs utifrån ett strategi- och organisationsperspektiv. Ambitionen är att t
Popular Abstract in Swedish Benskörhet (osteoporos) är en sjukdom som karaktäriseras av minskad mängd benmassa och försämrad benkvalitet. Benskörhet leder till en ökad risk för frakturer. Förekomsten av benskörhet har fördubblats under de senaste decennierna. Upp till en tiondel av alla män och en fjärdedel av alla kvinnor lider av sjukdomen. Ökningen av benskörhet i samhället kan delvis förklarasThe aim of this thesis was to evaluate long-term changes in bone mass and skeletal structure in the forearm in the peri- and postmenopausal period. 156 premenopausal women, at baseline aged 48 years, not taking medications and without disease processes known to interfere with bone metabolism, were followed through menopause by measurements of bone mass and skeletal structure at the cortical site o
Catalytic combustion is an important area of catalysis and is used in energy production as well as in the abatement of harmful emissions of various types. This thesis is focused on three different areas of catalytic combustion: - Catalytic combustion of diesel soot - Development of catalytically active wire meshes through thermal spraying - Stabilisation and activation of g-alumina for methane com
Our problem is how to design, with the use of distance and ICT, an appropriate academic context for learning, for students with no previous knowledge of this context. Our aim is to analyse and describe the learner’s relation to the object of his/her studies as part of his/her relation to the learning activity. By using a combination of a phenomenographic approach and activity system theory, we ana
An experimental and computational study of the nearwall combustion in a Homogeneous Charge Compression Ignition (HCCI) engine has been conducted by applying laser based diagnostic techniques in combination with numerical modeling. Our major intent was to characterize the combustion in the velocity- and thermal boundary layers. The progress of the combustion was studied by using fuel tracer LIF, th
Popular Abstract in Swedish Psykoterapi betraktas idag som en etablerad behandlingsform för människor med psykiska problem. Under senare hälften av 1900-talet växte intresset för alternativa behandlingsformer inom vårdsektorn, och en ansenlig mängd psykoterapeutiska metoder utvecklades. Under denna period tog även psykoterapiforskningen fart, med syfte att undersöka vilken betydelse olika behandliThe overall aim of the thesis was to investigate the effects of psychodynamically oriented psychotherapy and gain an increased understanding of the curative factors in psychotherapy by thorough examination of the therapeutic alliance and of client change. The core of the thesis is a naturalistic study of 22 short-term dynamic psychotherapies and a follow-up 6-12 months later. Individual outcome me
