Abstract: Systems and methods are described for modeling and analyzing utility structures according to applied loads. Particularly, a model engine can utilize inputs related to a utility structure, environmental conditions to which the utility structure is subjected, and engineering standards expected of the utility structure, and analyze the structure's loading and performance based on analysis configuration inputs. An engine or multiple engines can be run locally, or can be instantiated in a cloud to assist with multiple or complex calculations. Hybrid and geometric non-linear analyses and outputs can be performed or provided.

Abstract: An apparatus for providing an electrically controllable inductor which uses a first and a second magnetic core (20, 24) spaced apart from one another. A DC bias coil (22) is wound on the first magnetic core (20). An inductor coil (26) is wound on both the first magnetic core (20) and the second magnetic core (24). The inductance seen at terminal connections (80, 82) of the inductor coil (26) is variable in dependence upon a magnitude of a flow of direct current through the DC bias coil (22). In one embodiment of the inductor, the first and the second magnetic core (20, 24) are each formed using a pair of U-shaped core segments (30, 32, 60, 62) located adjacent to one another. In this embodiment, the first and second magnetic core (20, 24) are located in an opposing relation to one another, with the DC bias coil (22) wound on inner legs (64, 72) of the first magnetic core (20) and the inductor coil (26) wound on inner legs (64, 72, 34, 44) of both the first and the second magnetic core (20, 24).
