Abstract: The invention meeting the need identified above is the “Enhanced Database Propagation Program” or (EDPP). EDPP uses a cyclic member table that identifies a first source table in a cyclic relationship with a second source table. The first source table, identified in the cyclic member table, propagates first. EDPP replaces all foreign keys with “NULL” in the first target table. After the second source table in the subscription set has propagated to a second target table, EDPP updates first target table with the foreign keys from the first source table.

Abstract: The present system and methods enable simultaneous momentum dumping and orbit control of a spacecraft, such as a geostationary satellite. Control equations according to the present system and methods generate accurate station-keeping commands quickly and efficiently, reducing the number of maneuvers needed to maintain station and allowing station-keeping maneuvers to be performed with a single burn. Additional benefits include increased efficiency in propellant usage, and extension of the satellite's lifespan. The present system and methods also enable tighter orbit control, reduction in transients and number of station-keeping thrusters aboard the satellite. The present methods also eliminate the need for the thrusters to point through the center of mass of the satellite, which in turn reduces the need for dedicated station-keeping thrusters. The present methods also facilitate completely autonomous orbit control and control using Attitude Control Systems (ACS).

Abstract: A computer implemented method, apparatus, and computer usable program code for providing ply lay-up data for a composite part. A designation of a location is received for the composite part in a three dimensional object from a requester. A three dimensional model is opened in which the composite part is located.

Abstract: A computer implemented method, apparatus, and computer program product for copy-on-write optimization of immutable objects. An immutable object is marked as read-only to form a read-only object. The read-only object is formed to delay copying of the immutable object until a runtime determination is made that a write to the immutable object will be made. In response to an attempt to write to the read-only object, an internal value of the read-only object is copied to read-and-write storage using runtime information to form a writable copy of the read-only object. A set of references for the read-only object is updated to point to the writable copy of the read-only object. Delaying copying of the immutable object optimizes a copy-on-write of the immutable object.

Abstract: A Segment Interface Program (SIP) is disclosed that enables a user to choose locations in other applications to receive segments, and to mark segments for manual or automatic transmission to those applications. The SIP comprises an Application Interface Program (AIP), a Segment Creator Program (SCP), a Segment Queue Program (SQP), and a Segment Delivery Program (SDP). The SIP accesses a Rules database, a codes database, and a queue database. The AIP enables a user to select a location in an application and assign an application code and a location code to the location. The SCP enables a user to select a segment in a chat transcript, assign an application code and a location code to the segment, and send the segment to the SQP. The SQP receives the segment, assigns a queue number, and places the segment in a queue table. The SDP reads the user code, the application code and, when the application is active, sends the segment to the location in the application with the corresponding code.

Abstract: The present invention is method for scheduling jobs in a grid computing environment without having to monitor the state of the resource on the gird comprising a Global Scheduling Program (GSP) and a Local Scheduling Program (LSP). The GSP receives jobs submitted to the grid and distributes the job to the closest resource. The resource then runs the LSP to determine if the resource can execute the job under the conditions specified in the job. The LSP either rejects or accepts the job based on the current state of the resource properties and informs the GSP of the acceptance or rejection. If the job is rejected, the GSP randomly selects another resource to send the job to using a resource table. The resource table contains the state-independent properties of every resource on the grid.

Abstract: Replacing an object in an object oriented model in a computer system, by interrogating the model to retrieve information defining the relationships between the object to be replaced and other components of the model is described. These relationship definitions are then used to configure the replacement object within the model so as to assume corresponding relationships with the other components. There may be established as a part of the model functions to detect changes to the relationships between objects belonging to the model, and recording the changes in a registry. This registry is then interrogated to retrieve relationship definitions necessary to replace an object.

Abstract: Embodiments of the present invention provide a computer implemented method, apparatus, and computer program product for estimating, refining, and using the tare mass for an item to determine and monitor item depletion. In response to detecting an initial presence of an item in the storage unit, a controller collects data about the item. The controller then searches a database for a recorded item containing the same item identification. The tare mass of the item is set equal to the refined tare mass of the recorded item retrieved from the database. The tare mass is then used to calculate a depletion threshold for the item.

Abstract: A computer implemented method, data processing system, and computer program product for automatic discovery of the Java classloader delegation hierarchy. One or more classloaders are instrumented with byte code instrumentation code such that a delegation event is received each time a classloader delegates a resource finding method to a parent classloader of the classloader. From each delegation event received, the classloader that generated the delegation event and a parent classloader to which the classloader directly delegates the resource finding method is determined. Based on the delegation events received, the classloaders to which a current classloader in the one or more classloaders can directly delegate are determined. The order of delegation to the classloaders may then be determined.
