Accurate and less invasive personalized predictive medicine can spare many breast cancer patients from receiving complex surgical biopsies, unnecessary adjuvant treatments and its expensive medical cost. Cancer prognosis estimates recurrence of disease and predict survival of patient;hence resulting in improved patient management. To develop such knowledge based prognostic system, this paper examines potential hybridization of accuracy and interpretability in the form of Fuzzy Logic and Decision Trees, respectively. Effect of rule weights on fuzzy decision trees is investigated to be an alternative to membership function modifications for performance optimization. Experiments were performed using different combinations of: number of decision tree rules, types of fuzzy membership functions and inference techniques for breast cancer survival analysis. SEER breast cancer data set (1973-2003), the most comprehensible source of information on cancer incidence in United States, is considered. Performance comparisons suggest that predictions of weighted fuzzy decision trees (wFDT) are more accurate and balanced, than independently applied crisp decision tree classifiers;moreover it has a potential to adapt for significant performance enhancement. © 2008, Australian Computer Society, Inc.

Journal of Targeting, Measurement and Analysis for Marketing 2008年第1期16卷 57-67页

作者： Kondo, Fumiyo N Uwadaira, Yasuhiro Nakahara, Mariko Department of Social Systems and Management Graduate School of Systems & Information Engineering The University of Tsukuba Ibaraki Japan

This paper explores whether the sending of direct mail (DM) coupons via mobile phone increases the probability of beauty salon customers using a coupon when visiting the store. Customer research was conducted after the statistical analysis of an experiment in 2004, in which a mobile DM coupon did not positively affect customers' store visit probability, but a coupon sent on a postcard did. This research examines the promotional effects of three types of mobile DM coupon on the probability of shop visit, coupon use and additional service purchase by adding two types of mail that might induce customers to take an action for strengthening recall of receipt. The variable of mobile DM coupon availability was statistically significant on store visit. The variable of mobile DM coupon type was statistically significant on coupon use probability, with positive effects of hyperlink vs negative effect of ordinary mail or telephone reservation mail (ie ‘ordinary mail’, ‘hyperlink mail’ and ‘telephone reservation mail’).

作者： Lai-Yuen, Susana University of South Florida Department of Industrial and Management Systems Engineering University of South Florida United States

This paper describes the design and evaluation of two laboratory experiments that introduce LEGO Digital Designer and MINDSTROMS Education systems as meaningful means to reinforce concepts of micromanufacturing and industrial automation to engineering undergraduate students. The proposed laboratory experiments aim to complement the classroom lectures and to increase students' conceptual understanding and learning motivation. The first laboratory experiment introduces the LEGO Digital Designer as a 3D design program to better understand the micromanufacturing process through the virtual assembly of LEGO blocks. The second laboratory experiment uses LEGO Mindstorms NXT systems to provide students with hands-on team projects to design and build an automated system while applying concepts learned in the classroom. Data from students' projects and surveys is presented to evaluate the efficacy of the designed laboratory experiments on student engagement and conceptual understanding. © American Society for engineering Education, 2008.

2008 Workshop on NLP for Less Privileged Languages, held in conjunction with the 3rd International Joint Conference on Natural Language Processing, IJCNLP 2008

作者： Maung, Zin Maung Mikami, Yoshiki Management Information Systems Engineering Department Nagaoka University of Technology 1603-1 Kamitomioka Nagaoka Japan

Myanmar script uses no space between words and syllable segmentation represents a significant process in many NLP tasks such as word segmentation, sorting, line breaking and so on. In this study, a rulebased approach of syllable segmentation algorithm for Myanmar text is proposed. Segmentation rules were created based on the syllable structure of Myanmar script and a syllable segmentation algorithm was designed based on the created rules. A segmentation program was developed to evaluate the algorithm. A training corpus containing 32, 283 Myanmar syllables was tested in the program and the experimental results show an accuracy rate of 99.96% for segmentation. © 2008 Asian Federation of Natural Language Processing.

Teaching engineering and technology subjects involves conveying understanding of abstract information structures and processes such as complex telecommunications protocols, complex mathematical concepts, and data structures. These are multidimensional and can be difficult to grasp quickly. Supported by a Hewlett-Packard (HP) Technology for Teaching grant, the School of engineering and Technology at National University has embarked on a project to enable students to grasp these complex concepts more quickly and easily, using continuous dialog among students and instructors as the structures are first introduced and then examined from multiple perspectives through real-time interaction among students, small groups, and instructors. HP Wireless Tablet PCs are used to discuss and experiment with diagrams and processes in realtime. This allows combining lectures and problem-solving sessions into a single class session. Our hypothesis is that: 1) an in-depth learning of theory is accomplished, and 2) student engagement is enhanced. Presentation of theory by the instructor is integrated with application while the theory is still in the student's short-term memory. Students no longer have to wait for a separate session such as a recitation session to apply the concepts. This approach often takes less time. In addition to accelerating the learning process, expert instructors find this approach more rewarding as students grasp new concepts more quickly. Analysis of data captured from both students and instructors are presented to support our hypotheses, and our results are compared with similar research carried out by other universities. In addition, the level of interaction enabled by the use of HP Tablets in on-line classes is discussed. The best teaching tools available in existing on-line teaching platforms are compared with the additional tools available in on-site courses when every student has a wireless Tablet PC and specific recommendations are made to on-line teachi

Sintered Fergusonites NdNbO4 and YNbO4 were prepared by the hot-press method and their density, bending strength, elastic properties, micro-Vickers hardness, fracture toughness, and damping properties were measured. The damping capacities of NdNbO4 and YNbO4 were 6-7 % at 1 × 10-3 of the maximum surface shear strain. They increased with the maximum surface shear strain and reached 17-20%. The damping capacities of NdNbO4 and YNbO4 exhibited the maximum at room temperature, and decreased with increasing temperature. These values of damping capacities were higher than those of other representative ceramics. The microplastic strain of NdNbO4 and YNbO4 was caused at 10-5 MPa of stress. High damping behaviors of NdNbO4 and YNbO4 were caused by internal friction due to the movement of dislocations and twins which were observed by transmission electron microscopy.

2008 ASEE Annual Conference and Exposition

作者： Burack, Cathy Duffy, John Melchior, Alan Morgan, Eric Brandeis University University of Massachusetts Lowell United States Department of Mechanical Engineering SLICE Program Graduate Program Solar Energy Engineering Center for Youth and Communities Heller School for Social Policy and Management Solar Energy Engineering

SLICE is a multi-year initiative at the University of Massachusetts Lowell (UML) that is designed to embed service-learning opportunities for students throughout the undergraduate curriculum in the College of engineering, with the ultimate goal that each student would have at least one course every semester with a service-learning project. Since it began in 2004, thirty-seven full-time faculty members in the engineering college at UML have tried service-learning (S-L) in at least one of their courses over the last three years, out of an average of 70 faculty members who taught undergraduate courses. In 2003 there was one full-time faculty member engaged in S-L. As a result of SLICE, a total of 52 courses (35 of them required core undergraduate courses) taken by engineering students have had S-L integrated into them, with a total of over 700 student-courses each semester. This group of faculty members is perhaps the largest associated with a single engineering college using S-L. They were recruited in part by the principle of "start small rather than not at all." The program has a combination of grass-roots initiative and administration support. As part an ongoing evaluation, in depth interviews with fourteen faculty members who had tried SLICE were undertaken by experienced assessors of S-L projects from an outside university. All of the faculty members interviewed indicated that they saw SLICE as a valuable element in the engineering program, based on their own experience. All saw it as adding important dimensions to the learning experience that were not available through traditional classroom exercises, and all believed that it was consistent with efforts to broaden students' understanding of both engineering and their role in society. Finally, though all noted challenges with regard to implementation, they also indicated that the integration of S-L was worth the extra effort that it often involved. One faculty member even said, "It will change the way we think ab

2008 ASEE Annual Conference and Exposition

作者： Blessing, Jeffrey Mekemson, Kristen Pistrui, David Milwaukee School of Engineering Management Information Systems Program Milwaukee School of Engineering Kern Family Foundation Illinois Institute of Technology Chicago IL United States Department of Business IIT Acumen Dynamics LLC

The integration of entrepreneurship and innovation into undergraduate engineering education has been found to enhance student performance and improve retention rates (Ohland, 2004). It also prepares graduating engineers to work in rapidly changing environments defined by a competitive global marketplace. Industry is asking for engineers with better communication and teamwork skills, and most importantly, a broader understanding of how to solve real world problems and create value in the marketplace. While some engineering schools are beginning to integrate entrepreneurship and business concepts into the curriculum, many ABET-accredited schools are slow to react to the needs of industry and the marketplace. Recognizing that this problem is threatening the quality of U.S. engineering talent, the Kern Family Foundation established the Kern Entrepreneurship Education Network (KEEN) with the mission to create an action-oriented, entrepreneurial mindset among engineering, science and technical undergraduates. The KEEN initiative, launched in 2005, represents a new and unique entrepreneurial approach to improving undergraduate education in the U.S. This paper shows how building an entrepreneurial ecosystem within and among engineering schools, as exemplified by KEEN, will provide a strong foundation for graduating engineers entering organizations operating in an innovation-based economy. Ecosystems can be defined as environments with interconnected relationships influenced by a variety of factors. An entrepreneurial ecosystem links people by vision, commitment, passion, and innovation surrounding the achievement of a common goal. The paper has five objectives: (1) establish the need for an innovative and entrepreneurial talent pool coming out of U.S. engineering schools;(2) identify critical skills and abilities that can be taught to fulfill this need;(3) describe KEEN from its inception, documenting how new and innovative entrepreneurship-based undergraduate engineering e

In this paper we present the architecture for the Personal Autonomic Desktop Manager, a self managing application designed to act on behalf of the user in several aspects: protection, healing, optimization and configuration. The overall goal of this research is to improve the correlation of the autonomic self* properties and doing so also enhance the overall self-management capacity of the desktop (autonomicity). We introduce the Circulatory Computing (CC) model, a self-managing system initiative based on the biological metaphor of the cardiovascular system, and use its concepts in the design and implementation of the architecture.

2008 IEEE International Symposium on Electromagnetic Compatibility, EMC 2008

作者： Desideri, Daniele Maschio, Alvise Mattavelli, Paolo Department of Electrical Engineering University of Padova Padova Italy Department of Technology and Management of Industrial Systems University of Padova Vicenza Italy

A tool for the analysis below 100 kHz of pulsed current waveforms with reference to human exposure has been developed. It consists of a dedicated program written in Matlab. As input data, a trapezoidal pulsed current waveform has been considered, and, varying the rise time and the duty-cycle, a parametric analysis has been performed. Also a noise superimposed to the signal has been considered. Parameters relevant to human exposure have been calculated following the ICNIRP Guidelines. A schematic operative diagram for metal inert gas welding applications is proposed;an experimental set-up has been built and the obtained results are reported. © 2008 IEEE.
