Differential Protection for Arbitrary Three-Phase Power Transformers

This thesis describes how to provide standardized, current based, differential protection for any three-phase power transformer, including phase-shifting transformers with variable phase angle shift and transformers of all construction types and internal on-load tap-changer configurations. The use of standard transformer differential protection for such applications is considered impossible in the

Analytical Approximation of Contingent Claims

This PhD thesis consists of three separate papers. The common theme is methods to calculate analytical approximations for prices of different contingent claims under various model assumptions. The first two papers deals with approximations of standard European options in stochastic volatility models. The third paper is focused on approximating prices of commodity swaptions in a general model frame

Business Systems Analysis as Research

A business analyst who commences an investigation into design requirements for a new work system probably does not ‘label’ her inquiry process as research. However, a research perspective is needed if a productive learning spiral is to be established in which ‘useful’ systems can be created. Systematic, collaborative inquiry adopting an complex, open systems perspective is required in order to est

Protecting and transferring biotech inventions

The 2002/2003 joint masters students’ efforts deal with the general protection of inventions covering such issues as the concepts of industrial application, novelty and inventive step. The students are also i.a. taking a closer look at university inventions and biotechnology aspects such as the cloning of humans, patentability of stem cells, germ line intervention and animal suffering. The discuss
