XML is becoming a prevalent format and de facto standard for data exchange in many applications. While traditionally, lots of data are stored and managed in relational databases. There is an urgent need to research some efficient methods to convert these data stored in relational databases to XML format when integrating and exchanging these data in XML format. The semantics of XML schemas are crucial to design, query, and store XML documents and functional dependencies are very important representations of semantic information of XML schemas. As DTDs are one of the most frequently used schemas for XML documents in these days, we use DTDs as schemas of XML documents. This paper studies the problem of schema conversion from relational schemas to XML DTDs. As functional dependencies play an important role in the schema conversion process, the concept of functional dependency for XML DTDs is used to preserve the semantics implied by functional dependencies and keys of relational schemas. A conversion method is proposed to convert relational schemas to XML DTDs in the presence of functional dependencies, keys and foreign keys. The methods presented preserves the semantics implied by functional dependencies, keys and foreign keys of relational schemas and can convert multiple relational tables to XML DTDs at the same time

The Chinese information manipulation system is the base of the navigating system. Distinguishing the noise words from the significant words, and picking up the semantics from the text are unsolved difficult problems. We bring forward the information manipulation method combining the key indexing method with the whole-length indexing method, by comparing main indexing methods in common use in the information indexing system and taking the Chinese features of the internal information navigating system. Its implementation is also provided. This new method preferably provides the full and nicety retrieval and solutes the increasing problems of the indexing space. In the end, the indexing method to the data which is manipulated by the Chinese information manipulation system is also provided.

A learning system for a more complete process of learning to read aloud English words should consist of three major steps: alignment, mapping learning, and grapheme generation. In a previous paper, we discussed a basic alignment algorithm and several improvements that effectively accomplish the alignment and mapping learning simultaneously. In this paper, we focus mainly on grapheme generation. We present several criteria for constructing graphemes, and demonstrate that graphemes generated improve the predictive accuracy in learning to read aloud. © Springer-Verlag Berlin Heidelberg 1998.

Linear superposition principle is a basic characteristic of quantum mechanics. The quantum interference of matter wave results from this principle. Recently, considerable effort has been devoted to the study of the properties of superpositions of two or more coherent states, i.e. the Schr(?)dinger cat *** is shown that the superpositions of coherent states have properties different from those of the coherent state, such as the higher-order squeezing, sub-Poissonian distribution, oscillatory photon statistics and antibunching effect, because of the quantum interference between the components of the cat states. The emergence of these non-classical effects makes the study of the Schr(?)

作者： Iskander, M.F. Reed, T. Breen, J. III. Electrical Engineering Department University of Utah Salt Lake City Utah 84112 Dr. Iskander edited two special issues of theJournal of Microwave Power one on “Electromagnetics and Energy Applications” March 1983 and the other on “Electromagnetic Techniques in Medical Diagnosis and Imaging” September 1983. He authored one book onElectromagnetic Fields and Waves published by Prentice Hall 1992 he edited theCAEME Software Book Vol. I 1991 and coedited two books onMicrowave Processing of Materials one published by the Materials Research Society in 1991 and the second to be published in 1992. The holder of seven patents he has contributed 16 chapters to eight research books published more than 100 papers in technical journals and made numerous presentations in technical conferences. In 1983 he received the College of Engineering Outstanding Teaching Award and the College Patent Award for creative innovative and practical invention. In 1984 he was selected by the Utah Section of the IEEE as the Engineer of the Year. In 1984 he received the Outstanding Paper Award from the International Microwave Power Institute and in 1985 he received the Curtis W. McGraw ASEE National Research Award for outstanding early achievements by a university faculty member. In 1991 he received the ASEE George Westinghouse National Award for innovation in Engineering Education. He also received the 1992 Richard R. Stoddard Award from the IEEE EMC Society. In 1986 Dr. Iskander established the Engineering Clinic Program in the College of Engineering at the University of Utah. Since then the program has attracted more than 45 research projects from 18 different companies throughout the United States. He is also the director of the NSF/IEEE Center for Computer Applications in Electromagnetics Education (CAEME). He coorganized symposia on “Microwave Processing of Materials” held in conjunction with Materials Research Society meetings Springs of 1990 and 1992 in San Francisco. He also organized several workshops and special

With the availability of a large number of software packages for electromagnetic (EM) education through the national computer Applications in Electromagnetic Education (CAEME) Center [1] and other individual efforts, there have been some concerns regarding the ability to integrate this software effectively in routine classroom teaching. Basically, congested EM curricula do not provide instructors with sufficient time to include software demonstrations and simulations during class periods. It is also not clear whether students will be able, adequately and independently, to understand basic underlying concepts and physical phenomena from visualization of colorful graphics and from the output of performed simulations. To help integrate available EM software in classroom teaching for both instructor use and student independent study, CAEME developed three interactive video lessons for student instruction. Interactive media lessons integrate and allow individuals to interactively manipulate information from multimedia such as video, software, and animated graphics, and also include instructional information such as quizzes and tutorials. In this article, we present the features of three interactive video lessons in EM developed by CAEME. These lessons include tutorials, simulations from CAEME software and videos, and quizzes to evaluate student understanding. The lessons use animated graphics illustrating specific dynamic phenomena and specific measurement procedures. They also keep a record of student quiz scores for instructor use. These, as well as other features of the three developed interactive video lessons, and the software and hardware requirements for developing such lessons, will be described.
