This paper examines the causal relationship between growth and poverty reduction in developing countries between 1970 and 1998. For this purpose, we apply a modified form of traditional Granger causality tests to suit the short times series that are available, and use panel data model evaluation techniques to test the out-of-sample forecasting performance of competing models. We conclude that t...

A dynamic MAC (Medium Access Control) protocol demonstrator for ATM PON (Passive Optical Network) was realised and tested. The prototype is based on a SuperPON transport system, which allows implementing downstream grants per ONT (Optical Network Termination) or subdivided per T-Cont class (Transfer Container) and upstream requests by piggybacking or dedicated polling slots. The demonstrator pl...

We have studied both experimentally and numerically the dynamic effect of nonlinearity on lasing in disordered medium. The third-order nonlinearity not only changes the frequency and size of lasing modes, but also modifies the laser emission intensity and laser pulse width. When the nonlinear response time is longer than the lifetime of the lasing mode, the nonlinearity changes the laser output...

Renewable power sources such as wind and solar are inflexible in their energy production, which requires demand to rapidly follow supply in order to maintain energy balance. Promising controllable demands are air-conditioners and heat pumps which use electric energy to maintain a temperature at a setpoint. Such Thermostatically Controlled Loads (TCLs) have been shown to be able to follow a powe...
