Download or read book Fuzzy And Uncertain Object oriented Databases Concepts And Models written by Rita De Caluwe and published by World Scientific. This book was released on 1997-10-22 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enriching database models so as to allow the user to deal with fuzzy and uncertain information has been of scientists' concern for years. This resulted in numerous contributions, mainly with respect to the popular relational model or to some related form of it. The experience was instructive, although still far from concrete applications.The time has come that the advantages of object-oriented databases are acknowledged outside the research and academic worlds and a breakthrough of new commercial softwares is observed. Lately research has been devoted to the endowment of this type of databases with more real-world reflecting semantics. It proved that the object-oriented paradigm lends itself extremely well to it. This is very promising and opens new perspectives for the availability of new-generation database products in the near future.The book presents the latest research results in dealing with fuzziness and uncertainty in object-oriented databases.

This book was released on 2010-02-22 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is dedicated to the memory of Professor Ashley Morris who passed away some two years ago. Ashley was a close friend of all of us, the editors of this volume, and was also a Ph.D. student of one of us. We all had a chance to not only fully appreciate, and be inspired by his contributions, which have had a considerable impact on the entire research community. Due to our personal relations with Ashley, we also had an opportunity to get familiar with his deep thinking about the areas of his expertise and interests. Ashley has been involved since the very beginning of his professional career in database research and practice. Notably, he introduced first some novel solution in database management systems that could handle imprecise and uncertain data, and flexible queries based on imprecisely specified user interests. He proposed to use for that purpose fuzzy logic as an effective and efficient tool. Later the interests of Ashley moved to ways of how to represent and manipulate more complicated databases involving spatial or temporal objects. In this research he discovered and pursued the power of Geographic Information Systems (GISs). These two main lines of Ashley’s research interests and contributions are reflected in the composition of this volume. Basically, we collected some significant papers by well known researchers and scholars on the above mentioned topics. The particular contributions will now be briefly summarized to help the reader get a view of the topics covered and the contents of the particular contributions.

Download or read book Professional Uncertainty Knowledge and Relationship in the Classroom written by Joseph Mintz and published by Routledge. This book was released on 2014-06-27 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The extent to which teachers should make use of theoretical and expert knowledge as opposed to tacit experiential knowledge, and how these might be combined, is a perennial issue in discussions on pedagogy. This book addresses these debates through a creative development of the concept of productive uncertainty. Using case studies focusing on teachers working with children with autism, a particularly fertile crucible for considering uncertainty, the book explores how the radical 20th century psychoanalyst Wilfred Bion's epistemological approach to uncertainty can be used to re-frame Donald Schön's concept of reflection in action, offering a new perspective on the practice of teachers and other caring professionals. Several areas of potential uncertainty are identified, including uncertainty relating to areas of practice including diagnosis, the relationship between expert knowledge and practice, the implications of autism for autonomy and agency, and uncertainties in relation to the understanding of and use of new technologies. A strong argument is made, based on both theoretical and empirical grounds, that in juggling between theoretical and tacit knowledge in the classroom there is more to be gained by staying with the struggle with uncertainty than by fleeing from it too early, into the promise of expert solutions. Consideration is also given to the relative importance of specific theoretical training for teachers, both in general and in relation to working with children with special educational needs, in the context of international and UK policy developments in this area. This book will be of key value to researchers and postgraduates in the fields of education studies, teacher thinking and research, psychoanalytically informed psychosocial studies, as well as to practitioners working in special educational needs/autism education.

This book was released on 2012-12-06 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Software Engineering and Knowledgebase Systems (SOFfEKS) Research Group of the Department of Computer Science, Concordia University, Canada, organized a workshop on Incompleteness and Uncertainty in Information Systems from October 8-9, 1993 in Montreal. A major aim of the workshop was to bring together researchers who share a concern for issues of incompleteness and uncertainty. The workshop attracted people doing fundamental research and industry oriented research in databases, software engineering and AI from North America, Europe and Asia. The workshop program featured six invited talks and twenty other presentations. The invited speakers were: Martin Feather (University of Southern CalifornialInformation Systems Institute) Laks V. S. Lakshmanan (Concordia University) Ewa Orlowska (Polish Academy of Sciences) z. Pawlak (Warsaw Technical University and Academy of Sciences) F. Sadri (Concordia University) A. Skowron (Warsaw University) The papers can be classified into four groups: rough sets and logic, concept analysis, databases and information retrieval, and software engineering. The workshop opened with a warm welcome speech from Dr. Dan Taddeo, Dean, Faculty of Engineering and Computer Science. The first day's presentations were in rough sets, databases and information retrieval. Papers given on the second day centered around software engineering and concept analysis. Sufficient time was given in between presentations to promote active interactions and numerous lively discussions. At the end of two days, the participants expressed their hope that this workshop would be continued.

Download or read book Epistemology and Probability written by Arkady Plotnitsky and published by Springer Science & Business Media. This book was released on 2009-10-20 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an exploration of the relationships between epistemology and probability in the work of Niels Bohr, Werner Heisenberg, and Erwin Schro- ̈ dinger, and in quantum mechanics and in modern physics as a whole. It also considers the implications of these relationships and of quantum theory itself for our understanding of the nature of human thinking and knowledge in general, or the ‘‘epistemological lesson of quantum mechanics,’’ as Bohr liked 1 to say. These implications are radical and controversial. While they have been seen as scientifically productive and intellectually liberating to some, Bohr and Heisenberg among them, they have been troublesome to many others, such as Schro ̈ dinger and, most prominently, Albert Einstein. Einstein famously refused to believe that God would resort to playing dice or rather to playing with nature in the way quantum mechanics appeared to suggest, which is indeed quite different from playing dice. According to his later (sometime around 1953) remark, a lesser known or commented upon but arguably more important one: ‘‘That the Lord should play [dice], all right; but that He should gamble according to definite rules [i. e. , according to the rules of quantum mechanics, rather than 2 by merely throwing dice], that is beyond me. ’’ Although Einstein’s invocation of God is taken literally sometimes, he was not talking about God but about the way nature works. Bohr’s reply on an earlier occasion to Einstein’s question 1 Cf.

Download or read book Our Uncertain World written by Leslie Sawin and published by Chiron Publications. This book was released on 2023-12-20 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in times of uncertainty and anxiety. In these times, how can we best navigate our unknowns? Our Uncertain World answers that question through a Jungian prism. Carl Jung’s theory has helped many people through difficult times. Jungian perspectives facilitate such challenging navigation by not simplifying complexity but rather by finding the meaningful through-lines that guide the individual toward individuation even in the darkest of times. Using Jung’s unique multi-dimensional approach, this book offers insights and provides answers to questions about life in a state of three-dimensional flux. Our Uncertain World was born from the premise that we are in a period of ongoing change. The interlocking crises of COVID, national polarization, environmental disaster, and international war can undermine or even destroy the symbols, rituals, and mental structures that give meaning and coherence to our lives. These crises are explored in depth In the book’s three sections, Living with Personal Uncertainty over the Long Term, Social Turmoil: A Moment of Social change for Our Community and Our Nation, and Challenges Facing Our World: Grappling with the Environment, The Pandemic and War. The authors of this book accompany the reader through the current challenges we face and examine new ways of adjusting to the existing condition of protracted uncertainty. The book encourages the reader to articulate their own challenges and develop their own language to write, speak, and live within the reality of uncertain times. Our Uncertain World provides tools for individuals and groups to formulate new perspectives and life strategies for the current reality.
