This paper addresses methodic implementation of a credible ISHM capability for elements of Constellation systems. ISHM capability must be implemented by a combination of on-board and ground elements, each contributing to determining the health of systems in the most effective manner. Implementation of ISHM capability must evolve continuously to reach higher and higher levels of functional capability. The implication is that a sustainable approach must be defined in order to accomplish a believable capability. This paper describes the methodology, the elements, and the technology to implement ISHM capability throughout the life cycle of elements of Constellation systems, reaching beyond individual elements that might have a limited life while the constellation moves on.

This paper proposes a new high-speed reclosing operation method to improve the stability in power system with the fault current limiter. From an angular velocity, a field system voltage and a phase of the generator, the proposed operation method calculates the optimum reclosing time domain. The fault current limiter is used the reactance type or the resistive type. The examination was carried out using the Inst. of Electrical Engineers of Japan one-machine infinite bus system model in order to demonstrate the effectiveness of the proposed method. The Impact Ver2.3 was used in the computer simulation.

Enhancement of light extraction in a GaInN light-emitting diode employing a conductive omnidirectional reflector consisting of GaN, an indium-tin oxide nanorod low-refractive-index layer, and an Ag layer is presented.
In this paper the authors propose a structural method for a genetic algorithm (GA) for the optimization problem of cable routing in which cables have to be laid optimally. When there are no limits on the layout routes...

We present the use of the polysaccharide chitosan for immobilizing biomolecules on microfabricated device surfaces. The main advantages of chitosan are its abundance of primary amine groups and its ability to be electrodeposited. Biomolecules are easily attached to chitosan 's amines by standard glutaraldehyde chemistry. The electrodeposition of chitosan allows accurate spatial and temporal control of biomolecule placement. We have demonstrated this biofunctionalization method for two different bioMEMS devices: a biophotonic sensor and a micromechanical biosensor. We have successfully assembled probe DNA on each of them and detected hybridization with target DNA as a demonstration of sensor operation. Here, we briefly present the fabrication procedure and testing results for both of these bioMEMS sensing devices

An integral part of the curriculum in the recently developed Master of Science in Telecommunications systemsprogram at the University of Oklahoma - Tulsa is a laboratory course. The course is designed to enhance student understanding of fundamental computer networking principles and to expose students to research tools that can be used in carrying out their capstone research projects. Through a series of sequential laboratory modules, students learn to setup and configure simple to complex computer networks and to effectively employ commercial software tools for network design and performance analysis. Near the end of the course, working independently, each student is required to complete a final project that assimilates much of the reinforced and/or newly acquired knowledge and skills. This paper provides a detailed description of the laboratory course and its key project modules.

This paper presents a hybrid integration approach for heterogeneous heavy tailed traffic from multiple classes over a channel of known capacity, where the service times follow lognormal distribution. Using our hybrid integration approach, we formulate a procedure that can minimize delay while improving the channel utilization. We show that this approach yields lower delays than either the integrated or segregated approach described in published literature.
