To further the use of cluster and GRID resource, it is important to provide the user with a user friendly environment, providing command line utilities, graphical user interfaces and web access. This paper describes the tools developed for use at cluster at the Center for Technical and Scienti c Computing at Lund University, Lunarc.
This study gives a short description of nonequilibrium and many body effects in realistic simulation of intersubband emitters. Calculations are based on the self-consistent solution of the quantum kinetic equations under operating steady-state conditions. Scattering with phonons is included by means of a self-energy in the Dyson equation, and electron-electron interaction is treated in mean field
A series of twenty controlled experiments was undertaken to determine if heat treatment alters the speed, intensity, or appearance of wear on the edges of flint tools. Four hypotheses were tested with the following results: Heat-treated tools wore more quickly and with more severity than tools which had not been heated. When used in the same fashion and on the same materials, heat-treated flakes s
We consider the propagation in macro- and microcellular environments for systems with multiple antennas at both transmitter and receiver. We consider the important propagation effects that lead to (i) interdependency of directions-of-arrival and directions-of-departure, (ii) large delay and angle dispersion by propagation via far clusters, (iii) rank reduction of the transfer function matrix. We p
The paper provides a brief presentation of different production philosophies and their characteristics. How the one builds upon the other, and how those characteristics considered to be positive and of strong current interest are taken advantage of by developments underway in any given period are examined. Developmental trends that are evolving (NEXT STEP) or that can serve to complement the Lean
