We studied the flux pinning properties of BaZrO3-doped YBa 2Cu3O7-x and BaSnO3-doped YBa 2Cu3O7-x films. We found that BaSnO 3-doped films showed very high global pinning forces, Fp, of 28.3GNm-3 (77K, ) and 103GNm-3 (65K, ), twice that of BaZrO3-doped films. Transmission electron microscopy analysis showed that, in both films, nanorods of the dopant phase were incorporated. The BaSnO3 nanorods were nearly straight but the BaZrO3 nanorods became curved with the increasing film thickness. © 2008 IOP Publishing Ltd.

International Conference on computer Communications and Networks (ICCCN)

作者： Mickey Batson John McEachen Murali Tummala Graduate School of Engineering and Applied Science Department of Electrical and Computer Engineering Naval Postgraduate School Monterrey CA USA

In this paper, the unique nature of direction finding in an RF environment against an uncooperative emitter is presented. Specifically, the focus is on power management in a wireless antenna array. This paper will present two competing methods of power management. Both methods will use a Least Mean Squares (LMS) adaptive beamforming algorithm to compensate for grating lobes that are present in the arrays of this type. The first method creates a subset of sensors from a randomly distributed antenna array. This method uses data exclusively from these elements and increases the number of iterations until the desired beam is formed. The second method creates a new subset of sensors, from a randomly distributed array, for each iteration, until the desired beam is formed. The second method is observed to provide better power management across the sensor network. In addition it will be shown that the later technique also yields a substantially better defined beamwidth with reduced grating lobes for all of the frequencies simulated.

114th Annual ASEE Conference and Exposition, 2007

The electrical engineering program at the Milwaukee School of engineering (MSOE) has integrated a bilateral faculty teaching component into its international student exchange program. Considerable flexibility was needed to adjust to faculty availability and the major differences in academic calendars between the two institutions. Specifically, MSOE is a private institution on a quarter system and its partner university is the Lübeck University of applied sciences in Lübeck, Germany which utilizes the semester system and is a state university. Among the problems that needed to be overcome is that the semester versus quarter systems simply didn't align and neither institution has the resources to allow faculty absences for an entire academic year. At the Lübeck University of applied sciences the MSOE faculty generally teach a short intensive 2 week course at the end of the spring semester. An appropriate number of credits and associated grade are given and entered on both university transcripts. The Lübeck university faculty visit MSOE in the fall quarter to participate in the project defense of their own students who perform their Diplom Arbeit (senior thesis project) at a company generally in the Milwaukee region. During the visit the Lübeck faculty also provide a series of special topic lectures in various courses depending on the expertise of the faculty member. The benefits of the faculty exchange are many. Not just does the experience foster a stronger bond to the partner abroad, but the presence of the faculty serves to assure the students that the home institution is paying attention to their welfare and academic progress. The most essential thing we have come to believe is that while good academics are essential to a program, it is the relationships between the people involved in the program that determines a truly successful international program. The faculty exchange aspect has become a lynchpin of our exchange program. © American Society for engineering Ed

IEEE International Conference on Fuzzy Systems (FUZZ-IEEE)

作者： Luis Alberto Lucas Tania Mezzadri Centeno Myriam Regattieri Delgado Graduate School of Electrical Engineering and Applied Computer Science Federal University of Technology of Paraná (UTFPR) Curitiba Pernambuco Brazil

The aim of this work is to handle non-interval type-2 fuzzy logic systems (NIT2 FLS) in a simple manner. We retrieve an alternative representation of Type-2 fuzzy sets (T2 FS) that we call general footprint of uncertainty. Such representation, not only lets us easily visualize T2 FS in two-dimensions but also makes the understanding of basic operations and the inference procedure easier. We introduce the concept of supremum of a T2 FS and translation and cylindric extension for vertical slices to support the adopted inference mechanism, based on the scaled inference mechanism of Type-1 FIS. Finally, we propose a new defuzzification method, the vertical slice centroid type reduction, which requires low computational effort. Some calculations are presented to illustrate that the theory and simplifications proposed in this paper make NIT2 FLS, referred here as general type-2 fuzzy inference systems, much more accessible to FIS designers.

Current mammographic screeningfor breast cancer is less effective for younger women. To complement mammography for premenopausal women, we investigated the feasibility screening test using 98 blood serum proteins. Because the data set was very noisy and contained only weak features, we used a classifier designed for noisy data: decision fusion. Decision fusion outperformed both a support vector machine (SVM) and linear regression with forward stepwise feature selection on all three two-class classification tasks: normal tissue vs. cancer, normal tissue vs. benign lesions, and benign lesions vs. cancer. Decision fusion detected cancer moderately well (AUC=0.84 on normal vs. cancer), demonstrating promise as a screening tool. Decision fusion also detected benign lesions similarly well (AUC=0.83 on normal vs. benign lesions) and was the only classifier to achieve any success in separating benign from malignant lesions (AUC=0.64 on benign vs. cancer). The classification results suggest that the assayed proteins are more indicative of a secondary effect, such as immune response, rather than specific for breast cancer. In conclusion, the decision fusion classifier demonstrated some promise in detecting breast lesions and outperformed other classifiers, especially for the very noisy classification problem of distinguishing benign from malignant lesions. ©2007 IEEE.

Fault Tolerance for Super-Peers of P2P Systems

Fault Tolerance for Super-Peers of P2P Systems

Pacific Rim International Symposium on Dependable Computing

作者： Jenn-Wei Lin Ming-Feng Yang Jichiang Tsai Department of Computer Science and Information Engineering Fu Jen Catholic University Taiwan Graduate Institute of Applied Science and Engineering Fu Jen Catholic University Taiwan Department of Electrical Engineering National Chung Hsing University Taiwan

This paper presents an efficient fault-tolerant approach for the super-peers of peer-to-peer (P2P) file sharing systems. In the super-peer based P2P file sharing system, peers are organized into multiple groups. In each group, it has a special peer called super peer to serve the regular peers within the group. In this hierarchical architecture, if the super peer departs (fails), any file queries to its serving regular peers cannot be delivered. In the proposed approach, we propose a multiple publication technique to make each regular peer logically connect with two or more super peers in other groups. If a regular peer finds that its serving super peer cannot work, one of its other connected super peers will be selected as its new serving super peer to continuously process the file queries. To examine the effectiveness of the proposed approach, comprehensive simulations are performed to quantify the performance and overhead of the proposed approach.
