Numerical evaluation of potential integrals containing higher order hierarchical H(div) Legendre basis functions for parameterized quadrilateral surface cells

The singularity cancelation scheme initially introduced by Khayat and Wilton for evaluating singular and near-singular potential integrals with 1/R singularities has in this paper been applied to parameterized quadrilateral cells containing higher order hierarchical H(div) Legendre basis functions. The singular and near-singular potential integrals treated in this paper appear in the method of mom

Moral Hazard and Insurance: Optimality, Risk and Preferences

Popular Abstract in Swedish Försäkringsmarknader präglas generellt av informationsproblem av olika slag. I denna avhandling studeras ett specifikt sådant problem: moral hazard. Detta innebär att den försäkrade kan vidta försiktighetsåtgärder för att minska sannolikheten för att drabbas av en olycka, men att försäkringsbolaget inte säkert kan urskilja storleken på dessa försiktighetsåtgärder. Vi fåThe thesis consists of an introductory chapter, followed by three chapters which all deal with theoretical issues related to moral hazard and insurance. In Chapter 2 we assume symmetric and perfect information. We conclude that, given some standard assumptions, the expected utility function cannot be quasi-concave, which strengthens earlier findings in the literature. As a consequence convex prefe

Moisture Buffer Value of Building Materials

Building materials and furnishing used in contact with indoor air may have a positive effect to moderate the variations of indoor humidity seen in occupied buildings. Thus, very low humidity can be alleviated in winter, as well as can high indoor humidity in summer and during high occupancy loads. This way, materials can be used as a passive means of establishing indoor climatic conditions, which
