Geotouristic Approach to the Elements of Geocultural Heritage by Using UGAM Model: UNESCO World Heritage Site Felix Romuliana (Zaječar, Serbia)
Miloš Marjanović, Rastko Marković, Kristina Šarić, Aleksandar R. Radivojević, Aleksandar Antić, Đoko Raičević, Randall J. Schaetzl, Slobodan B. Marković (2024)This article presents a new Urban Geoheritage Assessment Model (UGAM) for the tourism potential of urban geoheritage. The model was applied to the well-known archaeological site Felix Romuliana (Serbia), so as to determine if the site has the potential to become an urban geosite. To support the UGAM model, a mineralogical-petrographical examination of the building stone available to visitors (both on the site and in the Zaječar National Museum) was carried out, and geological outcrops near the site were ......

Optimizacija površinskog kopa Ciganuša – Škorac
Vasilije Zejak (2024)U radu se govori o značaju optimizacije u savremenom rudarstvu i kako nam to softveri štede vreme, novac i olakšavaju procese planiranja.Konkretno u izradi ovog rada korišćen je softverski paket Whittle.Da bi se optimizacije mogla uspešno sprovesti, potrebno je konstruisati pre svega blok model ležišta kao i definisati niz tehno – ekonomskih parametara.

The number of unimodular roots of some reciprocal polynomials
Dragan Stankov (2020)We introduce a sequence P2n of monic reciprocal polynomials with integer coefficients having the central coefficients fixed. We prove that the ratio between number of nonunimodular roots of P2n and its degree d has a limit when d tends to infinity. We present an algorithm for calculation the limit and a numerical method for its approximation. If P2n is the sum of a fixed number of monomials we determine the central coefficients such that the ratio has the minimal limit. ...Algebraic integer, the house of algebraic integer, maximal modulus, reciprocal polynomial, primitive polynomial, Schinzel-Zassenhaus conjecture, Mahler measure, method of least squares, cyclotomic polynomials...
