Sistem poslovne inteligencije za upravljanje zaštitom na radu u rudarskoj industriji
Ljiljana R. Kolonja (2016-09-23)Postojeća organizacija zaštite na radu na površinskim kopovima uglja često nije umogućnosti da blagovremeno i tačno ukaže na nedostatke, koji mogu u bližoj ilidaljoj budućnosti da budu uzrok narušavanja bezbednosti radnika, ali i uzrokoštećenja materijalnih dobara rudnika. Nemogućnost donošenja pravovremenihodluka je moguće izbeći uvođenjem softverski podržanih sistema za praćenje ianalizu bezbednosti i zaštite na radu.Osnovni cilj ove doktorske disertacije je definisanje metodologije i razvoj modelasistema upravljanja zaštitom na radu, koji će omogućiti savremen, adekvatan isveobuhvatan način praćenja i analize ...... ons of the ACM, 54, 88‐98.

Modeliranje buke u urbanoj sredini u okolini Doma zdravlja u Pančevu
Stefan Mandić (2024)Prisustvujemo epohi gde buka predstavlja veoma rasprostranjen i moderan fenomen koji možemo deklarisati kao problem. Svedoci smo toga da moderni problemi zahtevaju malo drugačiji pristup nego u prošlosti, odnosno zahtevaju moderna rešenja. Samim tim, vremenom je došlo do modernizacije alata,u ovom slučaju došlo je do razvoja modela za rasprostiranje buke koji su se vremenom unapređivali pa tako danas imamo jedno moćno sredstvo za borbu protiv buke u vidu kompjuterskog softvera.Ovaј master rad, pod nazivom „Modeliranje buke u urbanoj sredini ...... and mitigate the impact of noise on people and the environment.

Marija Ilić, Franz-Hubert Haegel, Aleksandar Lolić, Zoran Nedić, Tomislav Tosti, Ivana Sredović Ignjatović, Andreas Linden, Nicolai D. Jablonowski, Heinrich Hartmann (2022)The knowledge ofthe structural and chemical properties of biochars is decisive for their application as technical products. For this reason, methods for the characterization of biochars that are generally applicable and allow quality control are highly desired. Several methods that have shown potential in other studies were used to investigate two activated carbons and seven biochars from different processes and feedstock.

Uticaj raspadanja na stabilnost kosina u mekoj stenskoj masi
Anđela Despotov (2024)U radu je opisano ponašanje mekih stenskih masa koje su izložene porecesu raspadanja tokom određenog vremenskog perioda. Meke stenske predstavljaju kritične vrste stenskih masa pošto izazivaju različite probleme tokom izvođenja građevinskih radova. Meke stene mogu biti sedimentne stene, raspadnute metamorfne i magmatske stene. Odlikuju se niskim vrednostima čvrstoće, visokom deformabilnošću, visokom plastičnošću, podložne su dezintegraciji i fizičko-hemijskom raspadanju, odnosno ubrzanom dejstvu površinskog raspadanja usled atmosferskih uticaja.Za klasifikaciju mekih stenskih masa koriste se modifikovane verzije već postojećih klasifikacionih sistema.

Старење бунара у алувијалним срединама различитог степена оксичности
Brankica Majkić (2013-09-27)Старење бунара настаје као последица процеса корозије и колмирања. Процесекорозије могуће је спречити уградњом филтерских конструкција од материјалаотпорних на корозију. Колмирање може да настане без обзира на врсту материјалаод кога се праве бунарске конструкције, а процесом може бити захваћенаприфилтарска зона па и зона саме водоносне средине.

Effectiveness Analysis of Different Bucket-wheel Excavators
Coal production in open-pit lignite mines in the Republic of Serbia is performed with continuous work systems. In addition to coal production, the same systems are used for the exploitation of large quantities of overburden. According to the reliability concept, continuous systems are in linear connection. If the failure occurs in one part of the system, that will produce a downtime of the entire system. The initial and most important factor of continuous systems is the bucket-wheel excavator.
