Towards an Analysis of Study Habits of University Students Open
This paper looks at the study workload for a sample of undergraduate students during 30 min intervals over 7x24 hours. Students at the Danmarks Tekniske Universitet in Denmark and the Universidad de los Andes in Bogotá, Colombia, took part…

The theory of track formation in insulators due to densely ionizing particles Open
We have devised a self-consistent scheme for modeling the evolution of the electrons and ions created along the track of a swift, densely ionizing particle passing through an insulator. Numerical implementation of the model has been made. …

Self-energies and the interactions of particles with surfaces Open
We have in this paper reviewed the method of treating many-body problems by means of an effective interaction self-energy. We have developed an alternatvie approach to the self-energy which is simpler and more straight-forward than standar…

Energy distributions of particles striking the cathode in a glow discharge Open
Charge-exchange collision in the cathode fall region of an abnormal glow discharge is assumed to be the mechanism which limits the energy of the ions and generates the energetic neutrals bombarding the cathode. The model used by W. D. Davi…
