Mathematica Special Interest Group (Washington DC Area)
Mathematica SIG (http://web.me.com/hrbishop.pmsi) MEETING 23 July 2010, 7:30 am Science Applications International Corporation (SAIC) 8301 Greensboro Drive McLean VA Southern Corner of Westpark Drive and Greensboro Drive Agenda 1. Prepared Talks "Counter Missile Design" by Mel Friedman ABSTRACT. A blue missile has fuel for T time units. It's fired when a red missile is closest and when T > tau (time to intercept). The blue missile always points toward the red (which travels in a straight line at constant altitude--assume a flat earth). I present an algorithm to determine when to fire the blue missile. "Dynamic Presentation of Geographic Data" by Dan Martinez ABSTRACT. Dan's Mathematica notebooks for this talk dynamically superimpose graphic objects onto topographic maps, which are shown as background images. Moving a slider enables users to display date-sensitive (using Boole and Pick) interactive graphic objects (using Tooltip and PopupWindow) in a LocatorPane. The application's data base structure and supporting functions are designed to facilitate many categories of spatial-temporal data. Three examples will be presented: Selected General Actions in the Napoleonic Wars, birthplaces and life-durations of US Presidents, and a hypothetical outbreak of communicable disease in the Continental US. 2. Mathematica Gems and Discoveries Sharing of Mathematica programming oddities Applications of Mathematica to some areas of science Something recently read and worth sharing 3. Mathematica Questions, Possible Approaches and Discussion 4. New Business Discuss time limits for presentations Discuss new way to publish agenda Select next meeting presentation, time and place --------------------------------- Directions to 8301 Greensboro Drive, McLean VA (tall, boxy and white SAIC Enterprise Building at south corner of Westpark Drive and Greensboro Drive): >From the Beltway, go northwest on Route 7 (Leesburg Pike) and proceed past Route 123 (Chain Bridge Road).
