We investigate the electron dynamics of p-type modulation doped and undoped InGaAs/GaAs quantum dots using up-conversion photoluminescence at low temperature and room temperature. The rise time of the p-doped sample is significantly shorter than that of the undoped at low temperature. With...

An approach to intersection delay analysis appropriate for representing turning movement delay at priority intersections in traffic assignment models is presented. The formulae are derived as an approximation to a dynamic queueing model by extending an approach adopted at the Transport and Road...
