Digital analyses of cartometric Fruska Gora guidelines

Modern geo morphological topography research have been using quantity statistic and cartographic methods for topographic relief features, mutual relief features, mutual connection analyses on the grounds of good quality numeric parameters etc. Topographic features are important for topographic activities are important for important natural activities. Important morphological characteristics are precisely at the angle of topography, hypsometry, and topography exposition and so on. Small yet unknown relief slants can deeply affect land configuration, hypsometry, topographic exposition etc. Expositions modify the light and heat of interconnected phenomena: soil and air temperature, soil disintegration, the length of vegetation period, the complexity of photosynthesis, the fruitfulness of agricultural crops, the height of snow limit etc. [Projekat Ministarstva nauke Republike Srbije, br. 176008 i br.

Digital topographic modelling in case with higher flood in the municipality Obrenovac

The town of Obrenovac is situated near the banks of three rivers, the Sava River, the Kolubara River and the Tamnava River. It looks like a modern town, though it has often developed in an unplanned manner. This causes huge problems as it thrives in a rough terrain, without a plan, which the communal infrastructure cannot follow. Today's needs in terms of spatial planning, envisaging projects and keeping track of a different kind of information on space demand that new technologies be applied since they make it possible for procuring efficient and reliable information as well as connecting and interconnecting various sorts of data. Also with advanced numerical GIS data and relief analysis we were successfully calculated consequence of the last big flood in 2014

The probability of flooding wave occurrence and the vulnerability of the Kosovo territory settlements

The work displays the presumed laws of flooding waves which would occur if the 1976 situation when the great floods in Kosovo happened reoccurred again. On a 1:300000 multilayer map of Kosovo and Metohia, there are areas which would have been flooded in case of a maximum flooding wave, and what is also shown is the areas which were covered in water as the average was measured, including the areas used as projects of minimal flooding wave value. There is a layer showing the points with regular flood defense, including the places where protection needs to establish. The map includes the ratio of 1:300000, whilst the areas are calculated with the help of processing their dynamic static’s, as well as using the formulae Gumbel Distribution and Weibull Formula. The data have been calculated with their maximum value, including the average and the minimum of flooding period embracing the time of 40 years. [Projekat Ministarstva nauke Republike Srbije, br.

New evidence for prehistoric copper metallurgy in the vicinity of Bor

The last three years of archaeological investigations at the site Ru`ana in Banjsko Polje, in the immediate vicinity of Bor, have provided new evidence regarding the role of non-ferrous metallurgy in the economy of the prehistoric communities of north-eastern Serbia. The remains of metallurgical furnaces and a large amount of metallic slags at two neighbouring sites in the mentioned settlement reveal that locations with many installations for the thermal processing of copper ore existed in the Bronze Age. We believe, judging by the finds of material culture, that metallurgical activities in this area also continued into the Iron Age and, possibly, into the 4th century AD

Numerical study of transient three-dimensional heat conduction problem with a moving heat source

A numerical study of transient three-dimensional heat conduction problem with a moving source is presented. For numerical solution Douglas-Gunn alternating direction implicit method is applied and for the moving heat source flux distribution Gaussian function is used. An influence on numerical solution of input parameters figuring in flux boundary conditions is examined. This include parameters appearing in Gaussian function and heat transfer coefficient from free convection boundaries. Sensitivity of cooling time from 800 to 500°C with respect to input parameters is also tested
