The Casimir energy for a conducting spherical shell of radius a is computed using a direct mode summation approach. An essential ingredient is the implementation of a recently proposed method based on Cauchy's theorem for an evaluation of the eigenfrequencies of the system. It is shown, however, that this earlier calculation uses an improper set of modes to(More)
A Galilean Chern-Simons field theory is formulated for the case of two interacting spin-1/2 fields of distinct masses M and M ′. A method for the construction of states containing N particles of mass M and N ′ particles of mass M ′ is given which is subsequently used to display equivalence to the spin-1/2 Aharonov-Bohm effect in the N = N ′ = 1 sector of(More)
The domain of Knowledge Intensive Process Improvement (Knowiπ)will be considered in this paper.F or the improvement of knowledge intensive processes (KnowiP) we suggest Genetic Algorithms (GAs). The representation needed by the GA depends on the modelling language of KnowiPs. We will use Petrinets for the process modelling and then use the incidence matrix(More)
