If you have read the article How Solar Cells Work, you have a basic understanding of solar-cell technology. A solar yard light uses standard solar cells in a very straightforward application. A single solar cell produces a maximum of 0.45 volts and a varying amount of current depending on the size of the cell and the amount of light striking ...
A simple graph with n vertices has a Hamiltonian path if, for every non-adjacent vertex pairs the sum of their degrees and their shortest path length is greater than n.  The above theorem can only recognize the existence of a Hamiltonian path in a graph and not a Hamiltonian Cycle.

Wireless mesh configurations allow local networks to run faster, because local packets don't have to travel back to a central server.
