Determining the Groundwater Balance and Radius of Influence Using Hydrodynamic Modeling: the Case Study of the Groundwater Source “Šumice” (Kikinda, Serbia)
A groundwater flow model was developed to simulate groundwater extraction from the public water supply source of the City of Kikinda. The hydrodynamic model includes the municipal groundwater source of Kikinda (Šumice and the Jezero Well), but also an extended area where there are groundwater sources that provide water supply to three factories: (MSK, TM and LŽT - Kikinda). Hydrodynamic modeling, based on the numerical method of finite differences will show the groundwater balance of the sources in the ...... org/10.1111/j.1745-6584.1980.tb03649.x 25.

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.

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. This paper uses fuzzy logic as a mathematical and conceptual model for selection of the optimal artificial lift method. The outcome or IF-THEN rules, as the central part of the model, is based ...... . , µA j, . . . , µA n); B = (µB 1, . . . , µB j, . . . , µB n); C = (µC 1, . . . , µC j, . . . , µC n); (2) M assessment is obtained in the form: µM = (MAXj=1, . . . , MAXj=10) = (µM 1, . . . , µM 10) where: MAXj = max{MINo}, for every j and MINo = min{µA j = 1, . . . , 10, µB j = 1, . . ...

Analiza pouzdanosti dozera angažovanih na površinskim kopovima RB Kolubara
U radu je izvršena uporedna analiza pouzdanosti transportnih sistema dozera koji rade na površinskim kopovima Rudarskog basena Kolubara. Period za koji je vršena analiza je prvih deset godina eksploatacije. Efikasnost tehnološkog procesa na otkopavanju korisne mineralne sirovine i otkrivke u velikoj meri zavisi od rada dozera. Iskorišćene su matematičke metode za aproksimaciju i identifikaciju zabeleženih vremena u radu, kako bi se dobili analitički pokazatelji pouzdanosti.
