I discuss a component-centered, aspect-oriented system, the Object Infrastructure Framework (OIF), NASA's initiative on Intelligent Synthesis Environments (ISE), and the application of OIF to the architecture of ISE. A critical issue in developing component-based and distributed systems is getting the assembled set of components to follow the policies of the overall system. To achieve ilities s...

This study conducted cold flow experimental research on the influence of mass rate atomization characteristics screw conveyer swirl injectors in an opening environment. The Phase Doppler Particle Analyzer (PDPA) and high-speed photography were utilized to obtain data. results showed that greatly influenced establishment working injectors. design point selection exerted significant range perform...

Patients with cancer often require computed tomography (CT) examinations to monitor the status of their disease. To enhance CT images, radiology personnel use power injectors to administer radiopaque contrast media at high pressures and controlled rates. If power injectors are used with implanted ports that are not designed to withstand pressures generated by the injectors, catheter ruptures ca...
