Mechanism to control and use window events among applications in concurrent computing
TL;DR: In this article, the authors propose an approach for real-time sharing of distributed applications based on a fundamental window hierarchical mapping and user interactions, which is event driven with agent assistance.

Access control for the services oriented architecture
Jun Li,Alan H. Karp +1 more
TL;DR: This paper demonstrates the benefits of FAccM over FIdM for SOA deployments and shows howFAccM can be implemented using the existing web services standards.
Patent
Method and apparatus to sense and multicast window events to a plurality of existing applications for concurrent execution
TL;DR: In this article, a global control window is used for multicasting window events to various application programs running on a computer system, each such program having an application window, and the global control program automatically multicasts each such event to every application program that the user has selected to receive incoming window events.
Patent
Intuitive file sharing with transparent security
TL;DR: In this article, a file sharing system includes authorization-based security to control access to shared files; and a synchronizer which uses the authorization based security to monitor the shared files for changes and propagate the changes according to sharing relationships.
Patent
Floating point arithmetic unit using modified Newton-Raphson technique for division and square root
TL;DR: A floating point processing system which uses a multiplier unit and an adder unit to perform floating point division and square root operations using both a conventional and a modified form of the Newton-Raphson method is described in this paper.
