Thermal annealing of the E(c) - 0.18 eV level in Czochralski-grown silicon crystals irradiated by Co-60 gamma rays has been investigated using Hall effect measurements. An anomalous annealing kinetics has been found, in which the centre disappearance probability is increased with isothermal annealing time. A tentative kinetic model of the process is proposed.

Extensive molecular-dynamics comput.r simulation results are presented for a two-dimensional (2D) Lennard-Jones system as it is compressed isothermally well beyond its normal liquid state. They show systematic changes in the pair distribution function and some of the time correlation functions as the system is transformed from a normal liquid into an amorphous state. The density correlation functions, however, start to exhibit a two-step relaxation process, a rapidly decaying component and a slowly decaying component indicating a structural slowdown, as the system is compressed. The density at which the transition to an amorphous state takes place has been estimated. Our results, when compared with those of three-dimensional systems, indicate that while the general behaviour is similar, the changes in 2D take place over a much smaller range of density. Implications of our results for localization and the Lindemann criterion are discussed.

The linear algebraic approach to queueing theory is applied to analyze the performance of a typical single-bus multiprocessor system. This system can be modeled as an M/G/1//N queueing system with load-dependent arrivals. The method presented requires only that the nonexponential service time distribution for the system be a matrix-exponential, that is, one with a rational Laplace transform. Using linear algebraic techniques, expressions are obtained for the performance characteristics of interest, such as the processing power for the multiprocessor system. The algorithm does not rely on root finding and can be implemented using symbolic programming techniques. The explicit closed form expression for the processing power is presented for some special cases.
