Generating all graph coverings by permutation voltage assignments
Discrete Mathematics, 1977 AbstractThis paper introduces the permutation voltage graph construction, which is a generalization of Gross's ordinary voltage graph construction. It is shown that every covering of a given graph arises from some permutation voltage assignment in a symmetric group and that every regular covering (in the topological sense) arises from some ordinary ...

An exploration of two infinite families of snarks [PDF]
, 2019 Thesis (M.S.) University of Alaska Fairbanks, 2019In this paper, we generalize a single example of a snark that admits a drawing with even rotational symmetry into two infinite families using a voltage graph construction techniques derived from cyclic ...

Distributed Adaptive Droop Control for DC Distribution Systems [PDF]
, 2014 A distributed-adaptive droop mechanism is proposed for secondary/primary control of dc Microgrids. The conventional secondary control, that adjusts the voltage set point for the local droop mechanism, is replaced by a voltage regulator.

Desynchronization: Synthesis of asynchronous circuits from synchronous specifications [PDF]
, 2006 Asynchronous implementation techniques, which measure logic delays at run time and activate registers accordingly, are inherently more robust than their synchronous counterparts, which estimate worst-case delays at design time, and constrain the clock ...

Voltage Distribution in Growing Conducting Networks
, 2002 We investigate by random-walk simulations and a mean-field theory how growth by biased addition of nodes affects flow of the current through the emergent conducting graph, representing a digital circuit.

Agent based modeling of energy networks [PDF]
, 2014 Attempts to model any present or future power grid face a huge challenge because a power grid is a complex system, with feedback and multi-agent behaviors, integrated by generation, distribution, storage and consumption systems, using various control and
