Evolution of population

The fission gas release microscopic model of the mechanistic code MFPR is further developed for modelling of enhanced release from irradiated UO2 fuel under transient conditions of the power ramp tests, along with the microstructure evolution characterised by the formation of a new population of large intragranular bubbles with a rather wide size distribution (from 30 to 500 nm), observed in transient-tested UO2 fuel samples.

MODELLING AIDS EPIDEMIC AND TREATMENT WITH DIFFERENCE EQUATIONS K. M. TAMIZHMANI, A. RAMANI, B. GRAMMATICOS, AND A. S. CARSTEA Received 15 October 2003 and in revised form 10 March 2004 We propose two models for the description of the dynamics of an AIDS epidemic and of the effect of a combined-drugs AIDS treatment based on difference equations. We show that our interacting population model, despite its extreme simplicity, describes adequately the evolution of an AIDS epidemic. A cellular-automaton analogue of the discrete system of equations is presented as well.

This thesis presents time-resolved measurements of the spin evolution of transient carrier populations in III-V quantum wells. Non-equilibrium distributions of spin polarisation were photoexcited and probed with picosecond laser pulses in three samples; a high mobility modulation n-doped sample containing a single GaAs/AlGaAs quantum well, an In0.11Ga0.89As/GaAs sample containing three quantum wells and, a multi-period GaAs/AlGaAs narrow quantum well sample.
