Fuzzy expert analysis of the severity of mining machinery failure
Mining machinery failure is almost an everyday occurrence. Usually the failures bare certain consequences, which require additional financial costs to repair and restore the system to its operational state. The consequences are viewed through negative and damaging effects a failure has on the machine, health and safety of the employees, work environment, and on the environment. The removal of the consequences of the failure requires additional financial investment, which has a negative impact on the company’s business. In order ...Dejan V.

Geotermalni potencijal pliocensko-kvartarnih sedimenata na teritoriji opštine Zemun
Matija Zorić (2024)Grad Beograd se nalazi na području koje je izuzetno bogato podzemnim vodama i hidrogeotermalnim resursima. Najveće količine podzemnih voda akumulirane su u okviru aluvijalnih peskovito-šljunkovitih sedimenata i krečnjaka tortonsko-sarmatske starosti. Opština Zemun ima najveći geotermalni potencijal od svih Beogradskih opština, čak 57.7% od ukupnog potencijala celog grada Beograda. Master rad je fokusiran na istraživanju i analizi poznatih tehničkih sistema, kao i termotehničkih sistema koji su u upotrebi na teritoriji opštine Zemun.

Geotechnical effects of municipal solid waste destruction with different compaction methods
Jovana M Janković Pantić, Dragoslav R Rakić, Irena G Basarić Ikodinović, Tina D Đurić, Gordana Hadži-Niković (2022)Disposal of waste in municipal solid waste landfills is the only way of waste disposal in Serbia, with daily compaction and covering with soil material. Due to less space for the construction of new landfills, it is necessary to use their maximum capacity. Well-compacted municipal solid waste takes up less volume and enables safer storage, so it is useful to previously determine the compaction parameters in the laboratory: maximum dry unit weight (γdmax) and optimal water content (wopt). In ...Jovana M Janković Pantić, Dragoslav R Rakić, Irena G Basarić Ikodinović, Tina D Đurić, Gordana Hadži-Niković.

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 ...... documents that were not retrieved. During the evaluation ranked responses were offered to users, and the measures P and R were calculated for sets containing the first i choices of- fered, where i ∈ [1, 120] [8]. In this way, curves showing the dependency between precision and recall for all 10 queries were ...
... ‘(gold OR Au) AND (Bor OR Bor district)’. For evaluation standard measures were used, namely Precision P = tp/(tp+ fp), Recall R = tp/(tp+ fn), and F- measure F = 2 ·P ·R/(P +R), where tp – true positive is the number of relevant documents retrieved, fp – false positive is the number of non-relevant documents ...

On the compatibility of lexical resources for NooJ
Lexical resources for many languages are provided for the NooJ linguistic development environment. Meta-data descriptions of morphosyntactic and semantic properties of these languages and their resources are a mandatory part of each language module. In this paper we analyze how well the meta-data actually describe resources for a chosen subset of languages and to what extent are they compatible across languages to support multilingual processing. We show that there is place for improvement in both directions.... d+IMP+AO+AO2+PDR+PDT+IMT+GPS+GP P+s+p+1+2+3+m+f+n+np+cp+sp Bg s+p+0+d+h+l+o+v+c+f+m+n+y+z+i+a+t+1+2+3+b+w+x+A+B+C+K+ P+F+M+N+R+E+D+I+Y+Z+X+W+Q Sr m+f+n+1+2+3+4+5+6+7+s+p+w+v+q+g+i+a+b+c+d+k+W+P+A+I+Y +G+T+F+S+X+x+y+z+h Table 4.

Tamara Đorđević, Ljiljana Karanović (2018)During systematic research on the mineral-related synthetic arsenates, with particular focus on their structural and spectroscopic classification, three new Sr-containing arsenates Sr2Mg(AsO4)2· 2H2O (1), Sr2Zn4(AsO4)4·H2O (2) and Sr2Cu7(AsO4)6 (3) have been synthesized under low-temperature hydrothermal conditions in the system SrO MO As2O5 H2O (M 2þ = Mg, Zn, Cu). Their crystal structures were determined using room-temperature single-crystal X-ray diffraction data and refined to the following R-values: 1– R1 = 0.025; 2– R1 = 0.030; 3– R1 = 0.035.
