Indexing of textual databases based on lexical resources: A case study for Serbian
In this paper we describe an approach to improvement of information retrieval results for large textual databases by pre-indexing documents using bag-of-words and Named Entity Recognition. The approach was applied on a database of geological projects financed by the Republic of Serbia in the last half century. Each document within this database is described by metadata, consisting of several fields such as title, domain, keywords, abstract, geographical location and the like. A bag of words was produced from these ...... Mitrović, J., Krstev, C.: Developing and Maintaining a WordNet: Procedures and Tools. In: Orav, H., Felbaum, C., Vossen, P. (eds.)

Ograničenja primene optimizacionih algoritama u slučaju kopova
Proces optimizacije površinskih kopova, kao sastavni deo strateškog planiranja, veoma je važan sa stanovišta ostvarivanja maksimalnih efekata proizvodnje. To je složen zadatak koji vrlo često podleže vrlo strogim geometrijskim i drugim praktičnim rudarskim ograničenjima. Ova ograničenja u posebno su izražena na površinskim kopovima uglja, te u značajnoj meri mogu povećati stepen neizvesnosti rudarskog projekta, odnosno izazvati neželjena dejstva u pogledu profitabilnosti poslovanja. Iz tog razloga, veoma je važna primena savremenih optimizacionih alata, koji u značajnoj meri mogu olakšati celokupan ...... povećava ukupan broj blokova u modelu.

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.

Improving efficiency of thermal power plants through mine coal quality planning and control
Главни циљ контроле квалитета угља у рудницима лигнита је снабдевање термоелектрана угљем чији квалитет мора да се креће унутар одређених квалитативних ограничења. Карактеристике угља могу да утичу на ефикасност, поузданост и расположивост како котла тако и јединица за контролу емисије. У овом раду аутори су презентовали интегрисану симулацију рударског процеса као нови приступ у истраживању променљивости калоричне вредности угља приликом експлоатације комплексног лежишта лигнита.

Testing the energy value of different types of coal by the method of active thermography
In this paper, coal thermograms are presented and analyzed in order to determine their energy value. Two types of coal of different categories, brown and lignite, were selected for active thermographic imaging. The tested coal samples were processed before measurement so that they are similar in dimensions and have two plane-parallel smooth surfaces. The test samples were "primarily" heated under the same conditions and the process of their cooling was monitored by a thermal camera. "Then" they were cooled ...Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Predrag Jovančić, Dragutin Jovković.

Availability as a dimension of energy security in the Republic of Serbia
Boban Pavlović, Dejan Ivezić (2016)There is a range of modern approaches and models in literature for the evaluation and determination of energy security, which are based on different parameters and indicators. For most of them, a common characteristic is emphasizing the avail ability of energy, as an important dimension for ensuring energy security. In this paper, concise overview of Serbian energy sectors is given and appropriate energy indicators are defined and determined. Selected indicators provide insight into the main components that characterize availability ...... as valuable tool to quantify diversity in a community and describe its numerical structure [16]. The index is calculated as the proportion of individual energy sources, n, relative to the total number of energy sources, N: ( ) 1 ln , n i i i i n H P P P N= = − =∑ (11) The higher value of ...
