A graph is called equistable when there is a non-negative weight function on its vertices such that a set S of vertices has total weight 1 if and only if S is maximal stable. We characterize those series-parallel graphs that are equistable, generalizing results of Mahadev, Peled and Sun about equistable outer-planar graphs.

This work presents four systems for generation of optical subcarriers in the C-band communications, based on serial and parallel amplified ring resonator with phase modulation 10 GHz spectral spacing between subcarriers. The were numerically simulated able to generate 83 145 output power levels −5 26 dBm an input 0 flatness 1.4 8 dB a minimum OSNR 30 dB.

Absorption cooling technologies converting excess heat and renewable resources to energy have shown progress in recent years. In this study, two 400 kW LiBr solution absorption chiller types with series parallel connected are analyzed over a range of parameter values better understand their applicability for different uses. Thermodynamic models the components were constructed validated. The per...

Recently, He and Yesha gave an algorithm for recognizing directed series parallel graphs, in time O(log n) with linearly many EREW processors. We give a new algorithm for this problem, based on a structural characterization of series parallel graphs in terms of their ear decompositions. Our algorithm can recognize undirected as well as directed series parallel graphs. It can be implemented in t...
