Distributed networking agent and method of making and using the smae

Abstract: The present invention relates to an agent for distributed networking and a processor-readable software code. The agent may include, for example, a cosite analyzer, an EMI sniffer, an asset controller module, an asset discovery module, and a link negotiator. The agent may be configured to initiate and optimize network configurations for radio communications systems based on parameters. The software code may receive data associated with a network plan, may determine if any planned links are included in the network plan and may establish connectivity of a confirmed link between at least two nodes in the network. Additionally, the software code may determine if a non-planned link should be added to the network and may establish connectivity for the non-planned link based on a priority associated with the non-planned link.

Planets and Comets: Role of Crystal Growth in Their Formation.

Abstract: The application of crystal growth theory to the formation of smoke particles from the primordial solar nebula indicates that solid particles with filamentary structures would form. Such particles would facilitate successive aggregation into planets, comets, and asteroids. The difficulties associated with the aggregation of spherical smoke particles would thus be avoided.

Moisture in Composites: The Effect of Supersonic Service on Diffusion

Abstract: Tests were conducted to determine whether aircraft flight conditions change moisture absorption behavior in graphite-epoxy composites. Flight temperature profiles were simulated for a subsonic mission, -65°F (-54°C) for 90 minutes, and for a flight involving a subsonic segment with a supersonic dash. The simulated dash involved rapid heating to a peak of 300°F (149°C) followed by rapid cooling. These simulated dashes or thermal spikes caused small, temporary drying effects. However, they also caused permanent changes in the subsequent moisture diffusion behavior of the graphite-epoxy. Both the amount and rate of moisture absorption were significantly increased. Subsonic temperatures, however, caused no detectable change in diffusion behavior.

Optical fiber launch coupler

Abstract: A low-loss unidirectional optical coupler utilizing clad monofilament fibers of different diameters is provided by mounting each fiber on a curved surface, lapping the smaller (launch) fiber substantially tangentially to the curved surface until the core of the launch fiber has been lapped through to produce two elliptical flat surfaces, independently lapping the other (throughput) fiber tangentially to its surface to produce a fiber surface of substantially the same size as one of those produced on the launch fiber, aligning the throughput fiber surface with one of the launch fiber surfaces, and bonding them together.
