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.

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.

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, the optimal routes for the individual cables can be found using the Dijkstra method in a finite discrete graph. However, when there are limits on the capacity in the layout routes, optimization cannot be performed using the Dijkstra method. The proposed GA is a two-level hierarchical GA that uses chromosome coding involving two levels. The routes for each cable and the combinations of cable routes are defined respectively, and layout route selection is optimized overall through genetic operations involving these levels. Block crossover and block mutation are used as genetic operations in the first level. In addition, a method to take advantage of lethal genes, which do not satisfy the constraints and are generated in the second level is used. computer simulations confirm that the two-level hierarchical GA with these genetic operations functions effectively for the optimization problem of cable routing. © 2006 Wiley Periodicals, Inc.

This article describes two demonstrations at the NTT Group Communication EXPO held at the Tokyo International Forum in December 2005. These showed visitors two of our trials on the feasibility of remotely operating instruments in Chile from Japan: an optical telescope and rock hammers in an underground copper mine. These applications use a relatively high bandwidth of around 100 Mbit/s and require short delay times for smooth interactive operation. To satisfy these requirements we used NTT's experimental research network GEMnet2 in collaboration with partner R&E (research and education) networks in North and South America. The demonstrations showed that Internet-based networks can handle interactive network applications with sufficient quality between two sites separated by almost the maximum possible distance on the Earth as long as the bandwidth and the route are carefully managed.

An appropriate definition and efficient computation of similarity (or distance) measures between two stochastic models are of theoretical and practical interest. In this work, a similarity measure, that is, a modified "generalized probability product kernel," of Gaussian hidden Markov models is introduced. Two efficient schemes for computing this similarity measure are presented. The first scheme adopts a forward procedure analogous to the approach commonly used in probability evaluation of observation sequences on HMMs. The second scheme is based on the specially defined similarity transition matrix of two Gaussian hidden Markov models. Two scaling procedures are also proposed to solve the out-of-precision problem in the implementation. The effectiveness of the proposed methods has been evaluated on simulated observations with predefined model parameters, and on natural texture images. Promising experimental results have been observed. © 2005 Hindawi Publishing Corporation.

2005 ASEE Annual Conference and Exposition: The Changing Landscape of engineering and technology Education in a Global World

Rochester Institute of Technology United States RIT Department of Electrical Computer and Telecommunications Engineering Technology United States Department of Mechanical Engineering and Materials Scinece and Engineering Department of Civil Engineering Technology Environmental Management and Safety Mechanical Engineering Technology Program RIT United States Department of Electrical Engineering

This paper describes the objectives, strategies, assessment and evaluation, and special program features of the Rochester Institute of technology's (RIT) Multi-department engineering and engineering technology (MEET) Scholars program. This program began in December, 2004 and is designed to recruit, retain and graduate additional transfer students in our selected engineering and engineering technology degree programs. The MEET Scholars program represents a collaborative effort of five academic departments across two colleges, and the Enrollment Management and Career Services Division at RIT. All of the programs in the five participating departments are ABET-accredited, and require students to obtain one year of industry co-op experience before graduation. The MEET Scholars program builds upon our excellent infrastructure for mentoring students, and involves our mandatory cooperative education program - both of which help students address their financial needs and facilitate placement in the high technology workforce. RIT has an exceptional record in engineering student placement in industry after graduation and an excellent record for both retaining and graduating upper-division transfer students.

作者： Barbe, David Thornton, Karen Green, James Casalena, Tony Weinstein, Matt Ghavam, Borna Robertson, Blake Maryland Technology Enterprise Institute Hinman CEOs Program University of Maryland College Park United States Department of Electrical and Computer Engineering United States

In Fall 2000, the Clark School of engineering at the University of Maryland, in cooperation with the Smith School of Business, created a unique residential entrepreneurship educational model - the Hinman Campus Entrepreneurship Opportunities (CEOs) program. The program is based on an input/output model in which the input is undergraduate students with a strong entrepreneurial drive;the system is an incubator-like entrepreneurial community environment and a variety of resources including education, networking, teaming and mentoring;and the output is students with substantial entrepreneurial knowledge and experience in operating real companies. This paper profiles four venture models operated by current Hinman CEOs students including students who are creating both high-tech and low-tech for-profit businesses.

Effectively teaching introductory media signal processing (MSP) to students requires a means of communicating complex concepts without advanced mathematics. At the Media Arts and technology program at UCSB we are teaching graduate media arts students concepts of MSP. These students, while interested in learning how their digital tools work, have an incredibly tough time working through the material the way traditional engineering students do. To address this we have used MATLAB to build a comprehensive suite of exploratory demonstrations and applications tailored to illustrate sophisticated concepts, and to inspire students that may not possess a strong background in mathematics. Our application, "Signals and Systems Using MATLAB" (SSUM), is presented here, and its use in a course designed to teach MSP to media arts students is discussed. Its usefulness extends beyond media arts to engineering and computer science curriculum. SSUM can be obtained for free from http://***/***. © 2005 IEEE.
