We investigate the nonlinear optical dynamics of excitons and trions in CdTe modulation-doped quantum wells by time and spectrally resolved pump-probe experiments. We find that the nonlinearities induced by excitons are different from those due to the pres ...
Experiments with a curved thi pinch show that the application of an oscillating axial current suppresses the usual toroidal drift of the plasma column and allows a stable, dynamic equilibrium to be established. ...
For a class of sensor networks, the task is to monitor an underlying
physical phenomenon over space and time through a
noisy observation process. The sensors can communicate back
to a data collector over a noisy channel. The key parameters
in such a se ...

A simple improved mixing cell model is shown to be more accurate than the standard mixing cell model when used to solve solute transport problems with a nonlinear adsorption isotherm included. The solution obtained from the improved model is found to agree ...
The paper presents a research 1that aims to develop a methodology that supports the elaboration and the optimisation of long term maintenance and renewal policies for railway infrastructure (strategic planning level, up to 20 years). The elaboration proces ...
Reputation mechanisms offer an efficient way of building the necessary level of trust in electronic markets. In the absence of independent verification authorities that can reveal the true outcome of a ransaction, market designers have to insure that it is ...
Details of the reliability and availability aspects of the thermoeconomic methodology presented in Part I (Olsommer et al., 1999) are given here in Part II of our series of two articles. These system details cannot be forgotten, particularly if the superco ...
