Integrisanje heterogenih leksičkih resursa
Osnovna aktivnost Grupe za obradu prirodnih jezika na Matematičkom fakulteta Univeziteta u Beogradu je usmerena na razvoj različitih resursa za obradu srpskog jezika. Među njima su posebno značajni sistem morfoloških rečnika srpskog jezika razvijenih u okviru mreže RELEX [1] i semantička mreža (tipa wordnet) za srpski jezik razvijena u okviru međunarodnog projekta Balkanet. Radi se o dva heterogena leksička resursa, razvijena na osnovu sasvim različitih modela, koji samim tim sadrže i različite vrste leksičkih informacija.

Specific electrical conductivity in epikarst groundwater of the eastern Suva Planina mt.
Branislav Petrović (2022)The epikarst is a part of the karst outcrop that is located within the unsaturated zone and represents a complex point of contact and mixing of unconsolidated material from the terrain surface. The correct and complete perception of epikarst, its degree of development and the presence on the limestone terrain can be achieved with a multidisciplinary approach.

Effect of natural gas composition on methane number: A case of gas reservoirs in Serbia
Natural gas is considered as the most environmentally acceptable fossil fuel, thus it is an alternative to petroleum derivate, dominantly used in internal combustion engines. Physical properties of a fuel as well as behavior during combustion process are affected by its composition. This article presents analysis of effect of natural gas composition on methane number (MN), conducted for natural gas deposits in Serbia.

Употреба веб платформе Омека за дигиталне библиотеке из домена рударства
У овом раду биће представљена Омека, веб платформа за приказивање дигиталних колекциjа и систем за управљање њиховим садржаjем. Њену примену у области техничких наука, а конкретно у области рударства, приказаћемо на примеру дигиталне библиотеке ROmeka@RGF. За Омеку смо се определили првенствено због чињенице да jе jедноставна за коришћење, има обимну пратећу документациjу и не захтева уско специфичне информатичке вештине што jе чини приступачном за већину корисника, а нарочито за рударске инжењере, коjима jе ова дигитална библиотека првенствено намењена.

Karst groundwater quantity assessment and sustainability: the approach appropriate for river basin management plans
Veljko Marinović, Zoran Stevanović (2019)As a result of the fact that karstified rocks can accumulate large amounts of high-quality groundwater, karst aquifer is considered, throughout the world, one of the most important types of aquifers. Due to their high permeability, but also vulnerability to pollution, these precious groundwater resources need to be properly evaluated and protected. Taking into account heterogeneity and complexity of the karst environment, it is difficult to propose a uniform algorithm for managing karst groundwater, which causes the necessity to ...Upravljanje karstnim podzemnim vodama, Pritisci na kvantitet voda, Plan upravljanja vodnim resursima, Bosna i Hercegovina, SrbijaVeljko Marinović, Zoran Stevanović.

Ecological status of the Lim river alluvium in Serbia
Amel Kurbegović, Boris Vakanjac, Vesna Ristić Vakanjac, Mirjana Bartula, Zorana Naunović, Nikola Milovanović, Jovan Kovačević (2022)Three countries share the catchment of the Lim River and they have been engaged in an eco-logical struggle for years, to conserve the river, its tributaries, and biodiversity. Honoring international conventions and declarations, along with active involvement of the civil society and support of Eu-ropean Union agencies, major efforts are being made to draw attention to the degradation of nature, especially water, which is essential for life on the planet Earth.

Fluid inclusion study in quartz of the Rudnik Pb-Zn-Cu-Ag skarn deposit, Serbia
Six types of fluid inclusions were identified in three growth zones of hydrothermal quartz from the Rudnik skarn deposit. In the core zone, primary two-phase fluid inclusions of high (type 1) and moderate salinity (type 2) homogenized to liquid between 350-430 °C and 340-420 °C, respectively. Raman analysis revealed that the vapour phases are a CO2-CH4 gas mixture, with a predominance of CO2.

A proposal for the landslide damage questionnaire in suburban areas
Landslides are one of the most often natural disasters that have an extensive impact on society including loss of life, destruction of infrastructure and properties, damage to land and loss of natural resources. Landslide losses can significantly vary and they depend on a variety of different criteria such as the size and type of landslide, lithological setting of terrain, the terrain slope gradient, the quality of materials used for construction, and the construction typology.

Imputing missing data using grey system theory and the biplot method to forecast groundwater levels and yields
Groundwater management is one of today’s important tasks. It has become necessary to seek out increasingly reliable methods to conserve groundwater resources. Dependable forecasting of the amounts of groundwater that can be abstracted in a sustainable manner requires longterm monitoring of the groundwater regime (rate of abstraction and groundwater levels). Monitoring of the groundwater source for the town of Bečej, Serbia had been disrupted for multiple years. The objective of the paper is to assess the possibility of reinterpreting ...Jelena Ratković, Dušan Polomčić, Zoran Gligorić, Dragoljub Bajić.

Uporedni prikaz proizvodnje električne energije iz uglja zemalja Evrope sa najvećim udelom: politika i projekcija proizvodnje
Energetski razvoj zemalja Evrope decenijama je bio baziran na uglju. Instalisana snaga svih energetskih kapaciteta koji su zasnovani na uglju je preko 2000 GW. Ugalj je i dalje od bitnog značaja za dobijanje električne energije u Evropi. I pored toga što postoji veliki potencijal uglja, trend je smanjenja proizvodnje električne energije iz uglja do 2050. godine. Imajući u vidu Zelenu agendu i politiku EU, zemlje Evrope se okreću obnovljivim izvorima energije.
