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):
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
