Hi, I have made a couple of attempts thus far at getting a unique golf swing analysis hardware/software application successfully completed but failed. Much of it has been due to me and unexpected elements encountered in the earliest versions attempted that needed to be altered, particularly on the software side. And now I need to get back to it and complete it successfully. It is not what I consider a complex application, at its most basic initially needing just two (ultimately wireless) orientation-type sensors placed on specific parts of the body, 3D orientation readings taken and synced together during a swing, and visual and mathematical comparisons of the orientations at various points of a swing (as rotated around to different angles on a 2D display). A properly operating software...

 What needs to be done: 
1. Calculate the number of links (ties) in each network of authors i.e. within one company, as well as the maximum possible number of ties between authors. That is, for example, a company can have 10 people, but only 5 of them copatented before => there is a connecti...
