For this first session we'll be talking about what volts, amps, etc. really are as well as covering a little bit of electric circuit network theory. So if, Thevenin or Norton mean nothing to you, and you're not sure what Rx1 and Rx10,000 mean you might want to stop by. If you have a meter please bring it. We'll have a couple of demo units available. http://en.wikipedia.org/wiki/Circuit_theory http://en.wikipedia.org/wiki/Network_analysis_(electrical_circuits) For the Lego Mindstorms we'll be moving forward on adding bump switches and modifying our code to accomidate it. We expect to be doing this for both meetings this month. Please let others know of our activity and invite them. If you have a project or other issue please come and share, we consider this an 'open microphone' event. Hope to see you all there! -- -- -- -- -- Venimus, Vidimus, Dolavimus James Choate jameschoate at austin.rr.com james.choate at twcable.com 512-657-1279 www.ssz.com http://www.twine.com/twine/1128gqhxn-dwr/solar-soyuz-zaibatsu http://www.twine.com/twine/1178v3j0v-76w/confusion-research-center Adapt, Adopt, Improvise -- -- -- -- From jameschoate at austin.rr.com Mon Sep 7 17:19:37 2009 From: jameschoate at austin.rr.com (jameschoate at austin.rr.com) Date: Tue, 8 Sep 2009 0:19:37 +0000 Subject: APM: Hacking Society Monthly Social Tue. 9-8-09 Message-ID: <20090908001937.CD5JE.280682.root@hrndva-web21-z01> Hello Everybody!

It's time to start planning to participate. The schedule... 7p - 8p Oscilloscopes -- If you have questions about what they are and how to use them, then this is for you. This is the first of two sessions. 8p - 8:30p The Robot Group -- Regular business. 8:30p - 10:00p Lego Mindstorms -- We are working on building several bots and supporting software. Currently we're doing bump switches and line following. We'll be moving forward to simple swarm applications in future sessions. These are considered "open micropone" events so feel free to bring your own projects to work on and share.

This can be seen as a two-player win-lose (zero-sum) game that we call the wiretap game. The value of this game is the greatest probability that the wiretapper can secure for hitting the virtual network. The value is shown to equal the reciprocal of the strength of the underlying graph. We efficiently compute a unique partition of the edges of the graph, called the prime-partition, and find the set of pure strategies of the hider that are best responses against every maxmin strategy of the wiretapper. Using these special pure strategies of the hider, which we call omni-connected-spanning-subgraphs, we define a partial order on the elements of the prime-partition. From the partial order, we obtain a linear number of simple two-variable inequalities that define the maxmin-polytope, and a characterization of its extreme points. Our definition of the partial order allows us to find all equilibrium strategies of the wiretapper that minimize the number of pure best responses of the hider. Among these strategies, we efficiently compute the unique strategy that maximizes the least punishment that the hider incurs for playing a pure strategy that is not a best response. Finally, we show that this unique strategy is the nucleolus of the recently studied simple cooperative spanning connectivity game. -- -- -- -- -- Venimus, Vidimus, Dolavimus James Choate jameschoate at austin.rr.com james.choate at twcable.com 512-657-1279 www.ssz.com http://www.twine.com/twine/1128gqhxn-dwr/solar-soyuz-zaibatsu http://www.twine.com/twine/1178v3j0v-76w/confusion-research-center Adapt, Adopt, Improvise -- -- -- --
