To get a flavor for how Lovasz' graph theoretic work helps untangle network snarls, check out his survey paper that has many examples using electronic current flow through a network:
He also has a cool interactive downloadable Windows application that illustrates the "rubber band method" of unsnarling networks for easier analysis (connections are stretched like rubber bands so that their graph has no lines crossing over each other, making for easier viewing):
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
