    The performance of a conventional microwave parabolic dish reflector can be estimated from a 35 mm photo, which is taken when the dish is illuminated by a small light bulb mounted at its feed point. Both random surface errors, structural deformations and feed positioning problems can be analyzed. If only go/no go-information is needed, no optical interferometry is necessary. View full abstract»

    Further cost reduction of the fiber optic gyroscope is necessary to meet the economic requirements of land navigation systems. Previous concentration was on the reduction of the number of splices and component improvements in the open-loop minimum configuration. Now non-essential components and splices are eliminated. The source-detector coupler is not part of the Sagnac interferometer, and serves... View full abstract»

    IriScan Inc. has been developing an identification/verification system capable of positively identifying and verifying the identity of individuals without physical contact or human intervention. A new technology, using the unique patterns of the human iris, shows promise of overcoming previous shortcomings and providing positive identification of an individual without contact or invasion, at extre...

    On the day that Raytheon bought Hughes Electronics, A.N. Chester described how aerospace executives evaluate options for research programs. Their objective is to develop products that have value after the planned work is completed. Big changes are taking place in the environment in which a new commercial product must succeed. By “environment” means the official and unofficial rules cre... View full abstract»

    This paper describes a security model developed from empirical data collected from a realistic intrusion experiment in which a number of undergraduate students were invited to attack a distributed computer system. Relevant data, with respect to their intrusion activities, were recorded continuously. We have worked out a hypothesis on typical attacker behavior based on experiences from this and oth...
