Extending the operating system to support an object-oriented environment

Abstract: Comandos is a project within the European Strategic Programme for Research on Information Technology - ESPRIT and it stems from the identified need of providing simpler and more integrated environments for application development in large distributed systems.The fundamental goal of the project is the definition of an integrated platform providing support for distributed and concurrent processing in a LAN environment, extensible and distributed data management and tools for monitoring and administrating the distributed environment.An object oriented approach was used as the ground level for the integration of the multidisciplinary concepts addressed in the project.This paper starts by describing the basic model and architecture of Comandos, which results from a common effort by all the partners in the project. We focus then on the description of a first prototype of the system, which implements a subset of the architecture and is currently running on a set of personal computers and workstations at INESC. The prototype is a testbed for the architecture, providing dynamic linking, access to persistent objects and transparent distribution. Special attention is given to the performance aspects of object invocation in virtual memory.

Signaling analysis for a multi-switch all-optical network

Abstract: Three signaling schemes are analyzed for their potential implementation in a high-speed multi-switch all-optical network. This investigation is of interest because important characteristics of all-optical high-speed networks were not considered in the design of signaling protocols currently implemented in today's networks. Equations for throughput and delay are derived for the three schemes and comparisons are performed. Results obtained identify the signaling scheme to be implemented on an all-optical networking testbed.

Dynamic air-bearing hardware-in-the-loop testbed to experimentally evaluate autonomous spacecraft proximity maneuvers

Abstract: Ground-based testbeds are critical to develop and test different elements of spacecraft guidance, navigation, and control subsystems. This paper provides an in-detail description of a state-of-the-...

Design and active control of a microgrid testbed

Abstract: Researchers at the University of Texas at Arlington (UTA) have installed a novel Microgrid testbed architecture that will be used for educational and research purposes. This paper documents the architecture of the UTA grid, the development of the national instruments based active control system, and some of the research progress made thus far. The specific commercial off the shelf components that make up the hardware in the system, which is actually broken up into three independent smaller grids, is described. A custom interconnection architecture will also be discussed that enables the three individual Microgrids to operate independently or in an actively interconnected mode of operation. The implementation of system control software will be presented in terms of the state machine used to develop the software. Finally, experimental data gathered from the dynamic performance of the Microgrid will be presented.
