Neural network congestion controller in prioritised ATM switch

A neural network (NN) scheme is proposed for congestion control in an ATM switch with time priorities. It is shown that in a prioritised switch it is necessary to monitor the buffer to be controlled as well as buffers with higher priorities. Furthermore, it is shown that the NN scheme in a time prioritised switch gives lower cell loss and delay when compared to the conventional binary scheme

Studies of AC electrical conductivity and initial magnetic permeability of rare-earth-substituted Li–Co ferrites

In the present work, the AC electrical conductivity and initial magnetic permeability were investigated for some Rare-earth-substituted spinel ferrites. These ferrites are of composition Li_0.5−0.5xCo_xFe_2.4−0.5xR_0.1O₄ (where x=0.0$x=0.0$, 0.5, and 1; R=Y, Yb, Eu, Ho and Gd). They were prepared by standard ceramic techniques. With respect to AC electrical conductivity, measurements show dispersion with frequency at low temperatures. This dispersion obeys the universal power law. The frequency exponent of the power law decreases with both Co ion content and temperature. This indicates that the classical barrier hopping mechanism is the predominant one in these samples. On the other hand, the behavior of the initial magnetic permeability with temperature exhibits multidomain structure only for the samples with x=0.0$x=0.0$, and single domain structure otherwise.
