1. 1. Pricing Portfolio Credit Derivatives

   Författare :Alexander Herbertsson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Portfolio credit risk; intensity-based models; dynamic dependence modelling; default contagion; CDS; synthetic CDO tranches; index CDS; k-th-to-default swaps; CDS-correlation; default-correlation; Markov jump processes; multivariate phase-type distributions; matrix-analytic methods;

   Sammanfattning : This thesis consists of four papers on dynamic dependence modelling in portfolio credit risk. The emphasis is on valuation of portfolio credit derivatives. The underlying model in all papers is the same, but is split in two different sub-models, one for inhomogeneous portfolios, and one for homogeneous ones. LÄS MER

3. 2. Dyspnea Experience and Quality of Life among persons with lung cancer in palliative care

   Författare :Ingela Henoch; Göteborgs universitet; []
   Nyckelord :Cancer Dyspnea Scale; CDS; Consequences; Content analysis; Coping; Depression; Dyspnea; Existential; Experience; Lung cancer; Management strategies; Palliative care; Quality of life; Reliability; Social support; Symptoms; Symptom experience; Validity;

   Sammanfattning : Background: Dyspnea, a subjective, multidimensional experience of breathing discomfort commonly occurring in patients with incurable lung cancer, influences all aspects of life in the suffering per¬sons. To optimally enhance quality of life (QoL) and to identify persons most vulnerable to this symptom, it is important to investigate how to assess dyspnea, how other symptoms and coping are related to dyspnea, and what the consequences of dyspnea are, especially on QoL.

4. 3. Effects of polymeric surfactants on the crystallisation of inorganic materials

   Författare :Per Kjellin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mesostructures; CdS; calcium carbonate; self-assembling phases; calcite; CaCO3; Ag; crystal polymorphs; nanostructures; surface active polymers; SrCO3;

   Sammanfattning : This thesis concerns effects of polymeric surfactants on the crystal growth of inorganic structures. The crystal growth of calcium carbonate on steel surfaces was studied with a heat exchanger cell and with an electrochemical method. LÄS MER

5. 4. Fabrication and Photoelectrochemical Applications of II-VI Semiconductor Nanomaterials

   Författare :Abhilash Sugunan; Muhammet Toprak; Mamoun Muhammed; Gerrit Boschloo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ZnO; nanowire arrays; photocatalysis; CdTe; CdSe; CdS; nanotetrapods; nanotetrahedrons; photoconduction; nano-gap electrodes; Type-II QDs; P3HT nanofibers; microwave synthesis.;

   Sammanfattning : In this work we investigated fabrication of semiconductor nanomaterials and evaluated their potential for photo-chemical and photovoltaic applications. We investigated different II-VI semiconductor nanomaterial systems; (i) ZnO oriented nanowire arrays non-epitaxially grown from a substrate; and (ii) colloidal CdE (E=Te,Se,S) quantum structures synthesized by solution-based thermal decomposition of organo-metallic precursors.

7. 5. Functional Metal Oxide Materials Deposited by Inkjet Printing Technique

   Författare :Yan Wu; Lyubov Belova; Gillian Gehring; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet printing; photoconductivity; ZnO; Al-ZnO; composite; electron transfer; CdS; field effect transistor; photosensitive; RT do-ferromagnetism; Mn-doped ZnO; MgO; Materials science; Teknisk materialvetenskap;

   Sammanfattning : This thesis presents a comprehensive study of the intrinsic room temperature ferromagnetism in 85 to 100nm thin films produced by in situ deposition of industrially important pristine MgO and ZnO by inkjet printing. It is suggested that the observed long range magnetic order, the so-called do magnetism in these oxides arises from cation vacancies. LÄS MER
