Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 32 reports theses submitted in 1987, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
Time is the one of the most important and complex attribute in managing databases and information systems. This book presents the importance of temporal logic in developing temporal database models and also indicates the important concepts in designing such systems. The book further investigates the representation of fuzzy data in the relational database environment and summarizes the important contributions in the field of temporal and fuzzy databases. Most of the proposed temporal database models are the extension of the classical relational model. The book further presents the key concepts for building ontological model to manage both temporal and fuzzy dimensions into database system. We have proposed a conceptual model called TempR-PDM which is an extension of the traditional entity relationship model and is extended to cover development of conceptual fuzzy-temporal relational model (FTRM). Patient data has been used to implement the model in practical form. This book addresses several aspects of temporal and fuzzy information in building database applications with emphasis on conceptual database model.
This third volume on Database Semantics looks at the link between Artificial Intelligence and Databases / Information Systems. Database / Information System design, implementation and operation is a complex problem-solving task, where expert knowledge is needed. Use of Artificial Intelligence techniques and principles may help to acquire, represent and manipulate this knowledge, resulting in the enrichment of database semantics.
We always seem to be comparing various conceptual structures in many of our higher mental activities. In any case, we use similarities and discrepancies in forming all our conceptual categories. In this book, the authors present a computerized approach to diagnosis: in particular, cognitive diagnosis. It uses fuzzy graph structures called fuzzy cognitive maps (FCMs). These are used in an attempt to model the intriacies of the higher mental processes. The area of structure comparison, focusing on measures of similarity and discrepancy, is also dealt with. A very interesting aspect of the book is how the authors approached the problem of cognitive diagnosis using fuzzy techniques. Some connections and differences from other approaches are also covered. The reader will find this book both informative and interesting.

Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.
