Wind Powering America engineering, into the curriculum. Supported by local businesses and utilities, small wind turbines at rural schools also introduce the concept of energy and the need for national strategic thinking on energy issues to the communities that participate in the program. To help states and Native American communities understand their wind resources, WPA created an anemometer loan program. Participants borrow anemometers and installation equipment to measure wind resources. Anemometer data can be used to help businesses, developers, farmers, ranchers, and homeowners determine wind potential in selected areas. Each anemometer collects wind speed data in 10-minute intervals. The data aid wind farm
Jordan measure finite union and intersection of Jordan measurable sets is Jordan measurable, as well as the set difference of any two Jordan measurable sets. A compact set is not necessarily Jordan measurable. For example, the fat Cantor set is not. Its inner Jordan measure vanishes, since its complement is dense; however, its outer Jordan measure does not vanish, since it cannot be less than (in fact, is equal to) its Lebesgue measure. Also, a bounded open set is not necessarily Jordan measurable. For example, the complement of the fat Cantor set (within the interval) is not. A bounded set is Jordan
