16. Isomorphism classes of abelian varieties over finite fields
Sammanfattning : Deligne and Howe described polarized abelian varieties over finite fields in terms of finitely generated free Z-modules satisfying a list of easy to state axioms. In this thesis we address the problem of developing an effective algorithm to compute isomorphism classes of (principally) polarized abelian varieties over a finite field, together with their automorphism groups.

17. Electric Fields for Surface Design and Chemical Analysis
Sammanfattning : This thesis deals with the use of electric fields for evaluation and control of chemical systems. An electric field can result in the flow of charge across an interface between a metal and a solution, by means of chemical reactions. This interplay between electricity and chemistry, i.e. LÄS MER
18. Microwave Gas and Multipactor Breakdown in Inhomogeneous Fields
Sammanfattning : Microwave gas and multipactor breakdown remains to be one of the limiting factors for the maximum power in microwave devices. Above a certain electric field strength, the so-called breakdown threshold, free electrons can multiply by making ionizing impacts with neutral gas molecules, or causing secondary emission upon impact with system surfaces.

19. Western esoterism : Ultimate Sacred Postulates and Ritual Fields
Sammanfattning : The greater part of Western Esoterism holds beliefs in five important matrices. This branch of esoterism, rooted in a Hermetic milieu, is labelled dialectical esoterism because of the dialectical relationship between the ‘lower’ (man, earth) and the ‘higher’ (heaven, the divine, God).
