Translations: Czech courtesy of Autip. Macedonian courtesy of Zoran Mitreski. Russian courtesy of Oleg Meister. German courtesy of Alexy Gnatuk. Romanian courtesy of Alexandra Seremina and Azoft. What economists call game theory psychologists call the theory of social situations, which is an accurate description of what game theory is about. In addition to game theory, economic theory has three other main branches: decision theory, general equilibrium theory and mechanism design theory. Decision theory can be viewed as a theory of one person games, or a game of a single player against nature. General equilibrium theory can be viewed as a specialized branch of game theory that deals with trade and production, and typically with a relatively large number of individual consumers and producers. Mechanism design theory differs from game theory in that game theory takes the rules of the game as given, while mechanism design theory asks about the consequences of different types of rules.

Held at the Galt House hotel, this year's conference offered a great mix of all things remote sensing over a three-day agenda. It was also co-located with a Joint Agency for Commercial Imagery Evaluation(JACIE) conference, which created a nice atmosphere where some of the best and brightest minds from science and academia could meet. Eyes in the Skies One of the most apparent trends I noticed at this show was the amount of exhibitors that had something to do with Unmanned Aerial Systems,or UAS. Other companies had their own planes and were offering to fly project sites as needed while several small systems were available for purchase direct from the vendor. ENVI User Group We also held our annual ENVI user group at the show. Finally, we wrapped up the session with an update on our enterprise and cloud-based technology. Off to the Races All in all, I think it was a great conference.
Game Theory First published Sat Jan 25, 1997; substantive revision Wed May 5, 2010 Game theory is the study of the ways in which strategic interactions among economic agents produce outcomes with respect to the preferences (or utilities) of those agents, where the outcomes in question might have been intended by none of the agents. The meaning of this statement will not be clear to the non-expert until each of the italicized words and phrases has been explained and featured in some examples. 1. The mathematical theory of games was invented by John von Neumann and Oskar Morgenstern (1944). Despite the fact that game theory has been rendered mathematically and logically systematic only since 1944, game-theoretic insights can be found among commentators going back to ancient times. Long before game theory had come along to show analysts how to think about this sort of problem systematically, it had occurred to some actual military leaders and influenced their strategies. 2. 2.1 Utility
Sapping Attention Data specification METI and NASA Announce Plans for ASTER Global DEM Release The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) was developed jointly by the Ministry of Economy, Trade, and Industry (METI) of Japan and the United States National Aeronautics and Space Administration (NASA). Initial studies to validate and characterize the ASTER GDEM recently were completed by NASA and METI, in cooperation with the U.S Geological Survey (USGS) and the Earth Remote Sensing Data Analysis Center (ERSDAC) of Japan, as well as with support from the U.S. ASTER Global DEM Following review of the validation results, METI and NASA have decided to jointly release the ASTER GDEM on June 29, 2009. The ASTER instrument was built by METI and launched onboard NASA’s Terra spacecraft in December 1999. The ASTER GDEM covers land surfaces between 83°N and 83°S and is composed of 22,600 1°-by-1° tiles.
