Fuzzy Model for Risk Assessment of Machinery Failures
The main goal of this research was the development of an algorithm for the implementation of negative risk parameters in a synthesis model for a risk level assessment for a specific machine used in the mining industry. Fuzzy sets and fuzzy logic theory, in combination with statistical methods, were applied to analyze the time picture state of the observed machine. Fuzzy logic is presented through fuzzy proposition and a fuzzy composition module. Using these tools, the symmetric position of the ......

Damage quantification of built stone on Dark Gate (Belgrade, Serbia): sample of damage index application for decay rate evaluation
The Dark Gate is the monument of culture, part of the cultural and historical complex of the Belgrade Fortress. It is constructed of limestone blocks that after 270 years of exposure to environmental conditions and different anthropogenic influences show wide ranges of decay forms. During 2007, detail registration of all built limestone microfacies and weathering forms was done using tools of monument mapping. A correlation scheme ‘‘intensity– damage category’’ was made according to the type, intensity, and distribution of ...... res- toration project, especially for purposes of assess weathering progression.

Mineragenetske karakteristike i potencijalnostjuvelirskih mineralnih resursa leckog vulkanskog kompleksa
Zoran Ž. Miladinović (2012-12-11)Jedan od najznačajnijih regiona u Srbiji, sa stanovišta potencijalnosti juvelirskih mneralnih resursa, predstavlja lecki vulkanski kompleks, tercijarne starosti i dominantno andezitskog sastava. Ovaj vulkanski kompleks površine preko 700km2 nalazi se u južnojSrbiji na prostoru imeđu Kuršumlije, Lebana i Medveđe.Prvi su pažnju na juvelirske mineralne sirovine ovog prostora obratili graditeljiJustinijane Prima-e (VI vek). Najintenzivnija istraživanja izvršena su u periodu 1980–1982. ali samo na malom prostoru krajnjeg jugoistočnog dela vulkanskog kompleksa.U Leckom vulkanskom kompleksu dominiraju andezitske stene i njihovi piroklastiti.Smatra se ...vulkanski kompleks, mineragenetske karakteristike, juvelirski mineralni resursi, nalazišta, potencijalnost, kvarc, ametist, ahat, kalcedon, jaspis, prognoza... .
