Information system trends influencing systems engineering

Abstract: Government and industry are focusing on “information” system technology to provide dramatic changes that will be the critical factors in a comprehensive range of activities from achieving-competitive-advantage to winning-wars. System, software, and security engineering for information systems involve principles and practices that continue to evolve. This paper identifies, compares, and questions those principles and practices. It characterizes the information system development/integration paradigms as being in a state of flux. In addition, architectural concepts are discussed that provide a framework for information system services that support a variety of missions and functions. Three salient points of the paper are: (1) system engineers should become familiar with “technical” information system architecture alternatives, (2) advances in technology are leading to the merging of system, software, and hardware engineering disciplines at the architectural level, and (3) requirements-definition and design-resolution procedures are being revolutionized through incremental/continuous development paradigms.

Method and device for measuring relevancy of a document to a keyword(s)

Abstract: A method is presented for ranking documents identified in a search relative to a keyword. The method utilizes a set of training documents to provide a co-occurrence matrix and a transition matrix. A word pair relevancy measure is calculated for each word of the document to be ranked. These word pair relevancy measures are based upon the co-occurrence and transition matrices obtained from the training set and are utilized to calculate a document relevance measure. Documents identified in a search are ranked utilizing the document relevance measure.

Method of converting computer program with loops to one without loops

Abstract: The present invention is a method of eliminating loops from a computer program by receiving the program, graphing its function and control, identifying its entry point, and identifying groups of loops connected to its entry point. Stop if there are no such groups. Otherwise, selecting a group of loops. Then, identifying the selected group's entry point. If the selected group includes no group of loops having a different entry point then replacing it with a recursive or non-recursive function, reconfiguring each connection entering and exiting the selected group to preserve their functionality, and returning to the fifth step. Otherwise, identifying groups of loops in the selected group connected to, but having different entry points and returning to the loop selection step.

Device for and method of network routing

Abstract: A device and method of routing traffic in a network by receiving the network, assigning a maximum temperature value to gateway nodes, calculating temperature values for router nodes, determining self-utilization values for nodes, determining neighborhood-utilization values for router nodes, determining pressure values for gateway nodes, determining pressure values for router nodes, identifying router node sent traffic, identifying neighboring nodes having higher temperatures than router node, identifying neighboring node with lowest pressure value, sending traffic to neighboring node with lowest pressure value, and stopping if the neighboring node is a gateway node, otherwise identifying the node as a router node and returning to the step of finding neighboring nodes.

Device for and method of determining changes to GUI

Abstract: A device and method of determining changes to a graphical user interface (GUI) that does not require the use of a configuration file or the use of data from a previous operation of an application computer program by identifying a program currently running, determining a first tree structure for the GUI, identifying a communication from the program to the GUI, returning to the third step if the communication does not change the GUI, determining a second tree structure for the changed GUI, comparing the first and second tree structures for any change, discarding the first tree structure, renaming the second tree structure as the first tree structure, and transmitting the identified change to a user, and returning to the third step.
