Influence of DEM resolution on numerical modelling of debris flows in RAMMS - Selanac case study
Debris flows induced by intensive rainfall represent very hazardous phenomena in many parts of the World. Methods for prediction of runout distance of flow like mass movements are different and depending on the input data, rheology, and available or appropriate numerical solution. However, sometimes it is not easy to obtain pre event and post event high-resolution data in the rural or mountainous area. Thus, the topology of terrain is the most important input parameter for the every real case ...... for a more quickly moving flow (Bartelt et al., 2013). Figure 1 The topography Z(X, Y) is given in the Cartesian framework, X and Y being the horizontal coordinates. The surface induces a local coordinate system x, y, z (Christen et al., 2010a) . It is discretized such that its projection onto ...

Using gravity data to define structural correlation affecting the formation of Neogene basins
A gravity survey can help to define the structural correlation in the study area. The structures that have influenced the development of Neogene basins can be defined using gravity data. By applying mathematical transformations to gravity data, the geological structures (faults, nappes, etc.) that impacted the formation of Neogene basins can be defined. We have taken the part of the Dinarides as the test region. The paper presents the results obtained using the procedure residual, vertical gradient, and total ...Snežana Ignjatović, Ivana Vasiljević, Branisav Sretković, Milanka Negovanović.

Prognoza operativne efikasnosti aktivnog podzemnog rudnika zasnovana na teoriji sivih sistema
Svetlana M. Štrbac-Savić (2016-06-10)Efikasnost predstavlja preduslov za opstanak svake rudarske kompanije, posebno u uslovima izuzetno konkurentnog trţišnog okruţenja kao što je to rudarska industrija. Efikasnost oznaĉava sposobnost kompanije da ispuni svoje kratkoroĉne ili dugoroĉne ciljeve. Operativna efikasnost se definiše kao odnos izmeĊu ulaznih parametara potrebnih za odvijanje proizvodnje i pokazatelja dobijenih proizvodnjom. U kontekstu rudarskog poslovanja, operativna efikasnost se odnosi na vreme potrebno da se mineralno dobro transformiše u novĉana sredstva.

Selection of Artificial Lift Methods: A Brief Review and New Model Based on Fuzzy Logic
Miroslav Crnogorac, Miloš Tanasijević, Dušan Danilović, Vesna Karović Maričić, Branko Leković (2020)Artificial lift methods have applications in oil wells where oil production is no longer possible due to natural reservoir energy, so this necessary energy is added by introducing lift methods. In order to achieve optimum production, the selection of an artificial lift method is very important.

... corresponding to different values of threshold V,,. The graph demonstrates that (S),, ~ Ts/r in a broad range of thresholds, and that the power-law exponent ¥z,; varies with threshold. As can be seen in inset, when the threshold increases, the exponent 75;r decreases (from the value 1.77 for very low thresholds ...Sanja Janićević, Dragutin Jovković, Lasse Laurson, Đorđe Spasojević.
