Taking the example of the 2004 United States presidential election, we show how this problem can be corrected using a cartogram—a map in which the sizes of regions such as ...

Bluetooth devices are typically arranged as piconets, which are further organized into scatternets. The formation methodology of such scatternets, to a large extent, dictates their efficiency. In this paper, we discuss and evaluate two “tree-based” algorithms for scatternet formation. Both these algorithms use an election mechanism to form master-slave relations, enabling piconet and scatternet...

If we view the states that make up the Electoral College as voters and make some simplifying assumptions, it is possible to use the theory of voting and voting power to measure the power of the individual states in a presidential election. Modeling the Electoral Coll...
