21. Any reliable system must be carefully designed to filter out electronic noise common on electrical networks . 22. Along with energy management, pumped storage systems help control electrical network frequency and provide reserve generation. 23. Maxwell's purpose in constructing this analogy was not to represent mechanical systems in terms of electrical networks . 24. Using various power harvesting devices, there is no need for wiring the sensors to an electrical network . 25. The vehicle is connected directly to the electrical network via specific socket and plug and a dedicated circuit. 26. For example, P . polycephalum has been modeled as a set of differential equations inspired by electrical networks . 27. The simulation may model electrical networks consisting of many thousands of nodes and containing several hundred generating units. 28. In any case, an electrical network at the base of the tower matches the antenna to its transmission line. 29. But, in September 1980, the lighthouse was connected to the public electrical network , thus making the acetylene lamp redundant. 30. Multiple edges are, for example, useful in the consideration of electrical networks , from a graph theoretical point of view.
