1. Construction of Adaptive Multistep Methods for Problems with Discontinuities, Invariants, and Constraints
Sammanfattning : Adaptive multistep methods have been widely used to solve initial value problems. These ordinary differential equations (ODEs) may arise from semi-discretization of time-dependent partial differential equations(PDEs) or may combine with some algebraic equations to represent a differential algebraic equations (DAEs).

Sammanfattning : The influence of acetylation on selected wood properties has been determined for Scandinavian pine and spruce wood, in order to predict the behavior of acetylated wood when it is used in different applications. Only minor differences in both bending strength and the modulus of elasticity were obtained for acetylated wood when compared with unmodified wood, and can, for practical applications, be considered unaltered.

Sammanfattning : This dissertation examines the last thirty years of internal reforms in the Swedish Government Offices. Analysis of the evolution of personnel politics, the formation of one agency and the attempts to introduce a collective activity planning model, show that the immediate problems of the early 1970’s – an over dimensioned staff, territory battles and unclear division of responsibility for personnel and organisation – remains to this day, notwithstanding the many reforms to approach them.

Sammanfattning : Nowadays, transition metal oxide catalysts are employed to a large extent in many chemical processes for the selective production of chemicals and intermediates. Although metal oxides are mostly known as oxidation catalysts, they can successfully catalyze a wide range of reactions, such as dehydration. LÄS MER
