The theory of belief functions assesses evidence by fitting it to a scale of canonical examples in which the meaning of a message depends on chance. In order to analyse parametric statistical problems within the framework of this theory, we must specify the evidence on which the parametric model is based. This article gives several examples to show how the nature of this evidence affects the an...

We consider a classically chaotic system that is described by a Hamiltonian H(Q,P;x), where (Q,P) describes a particle moving inside a cavity, and x controls a deformation of the boundary. The quantum eigenstates of the system are /n(x)>. We describe how the parametric kernel P(n/m)=//(2), also known as the local density of states, evolves as a function of deltax=x-x(0). We illumi...

JEL classification numbers: O3 and L8 2 ABSTRACT The diffusion literature implicitly assumes that a technological innovation remains homogeneous throughout the time period of the study with the sole modification being an assumed reduction in the real price of the technology over time. We argue that the technology can change in significant ways from one vintage to another to alter the nature of ...

Researchers and practitioners in many scientific disciplines and industrial fields are often faced with complex problems when dealing with comparisons between two or more groups using classical parametric methods. The data arising from real problems rarely are in agreement with stringent parametric assumptions. The NonParametric Combination (NPC) methodology frees the researcher from stringent ...

Keeping in the view the non-probabilistic nature of experiment, we introduced some new generalized exponential fuzzy entropy involving one or more real parameters and to check their authenticity, the essential properties of these measures have been studied. Introduced fuzzy entropies contain several other existing parametric and non-parametric measures of fuzzy entropies defined by De Luca and ...

Patterns in nature result from dynamic relationships of forces and constraints. What is analogous for patterns in art? Art is created by human hands motivated by inspiration and thought. It is the product of creativity and skill. Creativity is constrained by cognitive processes and skill by the limits of technology. Based upon the author’s studies of Oriental carpets, this paper suggests that p...

Introduction Measures of farm diversification Data and model specification Econometric results Discussion Summary and conclusions Acknowledgements References Appendix Abstract. Farm planning often focuses on optimal diversification with respect to risk, where the riskmanagement strategies combine production, marketing, financial and environmental aspects of the farmfirm. In this study an empiri...

Incomplete Nature is about an important and difficult subject: how life and mind evolved from a world of inanimate matter. It is also about what are the right concepts to use in understanding the nature and workings of life and mind. We need to be able to conceive them in such a way that it becomes intelligible that they could have arisen naturally from the kinds of inanimate processes describe...

Common using of parametric tests to elaborate research results is limited by predetermined assumptions (variable measurability, normality of its distribution, homogeneity of database etc), which must be fulfilled. Otherwise, the conclusions obtained by calculating using a parametric test will not be quite correct. Parametric tests are useless also in the case of the quality data and the data of...

A novel method is proposed to retrieve image sequences with the goal of forecasting complex and timevarying natural patterns. To that end, we introduce a framework called Memory-Based Forecasting; it provides forecast information based on the temporal development of past retrieved sequences. This paper targets the radar echo patterns in weather radar images, and aims to realize an image retriev...
