Morphisms of Dempster's Semigroup: A Revision and Interpretation
Daniel, Milan
2011 - English Analyzing three new approaches to interpretation, definition, and measurement of conflicts of belief Functions (BFs), we previously observed a possibility of expression of a BF Bel as Dempster's sum of non-conflicting BF Bel0 with the same plausibility decisional support as the original BF Bel has and of indecisive BF BelS which does not prefer any of the elements of frame of discernment. Based on this observation, the theory of homomorphisms of Dempster's semigroup (the algebra of non-extremal BFs on 2-element frame of discernment with Dempster's rule as its binary operation) is updated in the present contribution. New homomorphisms are introduced; their interpretation and relation to the original ones are presented. Keywords: belief function; Dempster-Shafer theory; Dempster's semigroup; conflict between belief functions; uncertainty; non-conflicting part of belief function; conflicting part of belief function Available at various institutes of the ASCR Morphisms of Dempster's Semigroup: A Revision and Interpretation

Traditional Measures of Diversity, Their Estimates and Sensitivity to Changes
Horáček, Martin; Zvárová, Jana
2011 - English We dealt with the traditional measures of diversity and their sample estimates. We proposed a new estimator of measures of diversity and we studied a way to compare sensitivity to changes of different measures of diversity. The proposed estimator compares favorably to other well established estimators. The sensitivity of measure of diversity to changes could be used to compare behavior of different measures of diversity and to select those that are the most suitable for a given problem. Keywords: biodiversity; generalized entropies; sensitivity Available at various institutes of the ASCR Traditional Measures of Diversity, Their Estimates and Sensitivity to Changes

E-learning and the Impact of Information Delivery to Students and Patients in Multilingual Setting
Zvárová, Jana; Dostálová, T.; Zvára Jr., Karel; Seydlová, M.; Papíková, Vendula; Zvolský, Miroslav
2010 - English Particularly important in educational programmes and knowledge dissemination is the role of the Internet. We show several approaches how to use Internet and Web 2.0 based e-learning tools in doctoral and lifelong education. Within the fields of health and medicine there are three main areas, where the e-learning approach has been applied: medical training, research translation and health literacy. We show some e-learning tools, especially interactive books, interactive programs and system ExaMe, using examples from the field of dentistry. We also concern with problem of transferring knowledge in different languages using Internet based European Journal for Biomedical Informatics. Keywords: e-learning; knowledge; evaluation; dissemination Available on request at various institutes of the ASCR E-learning and the Impact of Information Delivery to Students and Patients in Multilingual Setting

Stochastic Modeling of Biodiversity: f-diversity, self f-diversity and Marginal f-diversity
Zvárová, Jana; Zvára, Karel
2010 - English The paper is devoted to stochastic modeling of biodiversities, that are presented as selected f-diversities frequently used in biology and medicine. The most often used in biology and medicine are f-diversities called Number Alles, Gini-Simpson diversity and Shannon diversity. We have introduced two new general concepts, named marginal f-diversity and self f-diversity. The statistical properties of sample estimates of the selected f-diversities are mentioned. Results of simulations of f-diversities, self f-diversities and marginal f-diversities for Number Alles, Gini-Simpson and Shannon type diversities on the example of three alleles with fixed probabilities of occurrence and several sample sizes used are presented. Keywords: biodiversity; modeling; f-entropy; f-diversity; self f-diversity; marginal f-diversity Available at various institutes of the ASCR Stochastic Modeling of Biodiversity: f-diversity, self f-diversity and Marginal f-diversity

Belief Conditioning in DSmT
Daniel, Milan
2009 - English Basic notions from both Dempster-Shafer theory and DSmT (Dezert-Smarandache theory) are briefly reminded, followed by a recapitulation of the existing results on DSm conditioning. Analogically to the analysis of belief conditioning in the classical case, the existing DSm belief conditioning rules (BCRs) are analysed and the new generalized plain BCR is defined, a general formula for DSm BCRs is presented, and the general DSm BCR is defined. Further, the negative conditioning in the lattice based DSm approach is introduced, the negative plain and negative Dempster's BCRs are defined and first results of these new rules are presented. Finally a wide area of open problems of negative DSm belief conditioning and its relation to positive conditioning is sketched. Stručné připomenutí základních pojmů z Dempster-Shaferovy teorie i DSmT (Dezert-Smarandacheovy teorie) je následováno připomenutím stávajících výsledků o DSm podmiňování. DSm pravidla pro podmiňování domnění jsou analyzována analogicky analýze podmiňování domnění v klasickém případě. V příspěvku je definováno nové zobecněné "plain" podmiňovací pravidlo a jsou zde prezentovány zobecněné formule pro DSm pravidla pro podmiňování domnění. Dále je zavedeno negativní podmiňování v DSm svazové struktuře. Je zde definováno negativní "plain" a negativní Dempsterovo podmiňovací pravidlo a jsou prezentovány první výsledky o těchto nových pravidlech. Závěrem je nastíněna široká oblast otevřených problémů negativního DSm podmiňování a jeho vztah k pozitivnímu podmiňování.
