This paper presents an intelligent database system to support petrographic analysis. The main goal of the research is to solve problems in knowledge acquisition and representation to develop efficient systems in domains with weak theory. The proposition of this work is to use case-based reasoning technology coupled with a database system to develop systems that store and manage the information ...

In this paper, the connection between Menger probabilistic norms and H"{o}hle probabilistic norms is discussed. In addition, the correspondence between probabilistic norms and Wu-Fang fuzzy (semi-) norms is established. It is shown that a probabilistic norm (with triangular norm $min$) can generate a Wu-Fang fuzzy semi-norm and conversely, a Wu-Fang fuzzy norm can generate a probabilistic norm.

Background: Traditional techniques for preparation of teeth for histological analysis include: 1) Ground section of non-decalcified tooth and view by polarized light. 2) Decalcify the tooth and then section and stain as per soft tissue. 3) Cryomicrotomy -non-decalcified tooth is immersed rapidly in liquid nitrogen and sectioned with a cryostat using a heavy-duty freezing microtome. Objectives: ...

The tonsteins were found in the coal seams of all divisions Carboniferous deposits Donbas. They are thin clay interlayers kaolinite composition and, according to most researchers, volcanic origin. object this study is Lower Western Analysis chemical ton - steins indicates their predominantly composition. aluminosilicate modulus (Al2O3 /SiO2 ratio) for from a number mines Donbas close norm (0.85...

In addition to the standard description of structures and textures crystalline rocks mathematical approaches have been proposed based on a rigorous determination petrographic structure through probabilities binary intergrain contacts. general, is defined as an invariant aspect rock organization, algebraically expressed by canonical diagonal form symmetric Pij matrix geometrically visualized str...
