Abstract: Simulation of a computational job using various sets of resources, and potentially also the automated or semi-automated allocation of an appropriate set of resources for accomplishing a computational job comprising multiple vertices. For each of multiple potential sets of resources, a simulation module simulates processing of the computational job. While the simulation does not actually perform the vertex on each processing node, the simulation does use dependencies between vertices, and historical data regarding the processing of instances of such vertices, in order to determine the efficacy of processing of each vertex, and to put the estimations together into an overall simulation result.

Abstract: One embodiment is a method that uses a Single Sign On (SSO) infrastructure in an application for creating a security context that identifies a user. The application then passes the security context to a second application and to the user as a cookie. The cookie is passed back to applications to enable SSO access to resources.

Abstract: A method for sensing and monitoring ICBM threats using a constellation of earth orbiting satellites. The method includes arranging a first and a second plurality of threat sensing satellites in earth orbit. The first plurality is selected to have a first prograde orbit plane with a first inclination angle between about 30° to 70° with respect to the earth's equator and an Argument of Perigee equal to about 270°. The second plurality is selected to have a first retrograde orbit plane with a second inclination angle between about 110° to 150° with respect to the earth's equator and an Argument of Perigee equal to about 270°. The second inclination angle is selected to be a symmetric conjugate of the first inclination angle. The first and second plurality of threat sensing satellites are distributed respectively within the first prograde and first retrograde orbits with a Walker distribution of T/P/1.

Abstract: A real time radiographic test system comprises a protective housing and a conveyor for conveying articles to be tested through the housing. A real time radiographic test instrument is located in the housing for performing a real time radiographic test on the article. The real time radiographic test instrument includes X-ray equipment disposed for directing an X-ray beam within the housing in a direction which does not intersect the conveyor. An article-handling actuator is located in the housing for repositioning an article from the conveyor to a position in registry with the X-ray beam, for maintaining the article in registry with the X-ray beam while the real time radiographic test is performed on the article and thereafter returning the article to the conveyor. The article-handling actuator and the X-ray equipment are designed such that each article to be tested is positioned substantially identically relative to the X-ray beam.
