Introduction: The high-voltage fields that are of current environmental interest are the fields associated with the transmission of electricity. Since electricity is often generated at sites that are remote from the points of consumption, some means of electrical transmission is required. Most of this transmission is accomplished with overhead transmission lines. The increase in the demand for power and the economies that can be realized when electricity is tansmitted at...

Excerpt: An algebraic variation principle. On the formal side of dynamics it has proved to be a fact of fundamental importance that the differential equations can in general be obtained by demanding that the 'variation? of some definite integral vanishes. To make clear the essential nature of the variation method, we may consider an analogous question concerning ordinary maxima and minima. Let there be given n equations in rt unknown quantities.
