Keyword-Based Search on Bilingual Digital Libraries
This paper outlines the main features of Biblisha, a tool that offers various possibilities of enhancing queries submitted to large collections of aligned parallel text residing in bilingual digital library. Biblishsa supports keyword queries as an intuitive way of specifying information needs. The keyword queries initiated, in Serbian or English, can be expanded, both semantically, morphologically and in other language, using different supporting monolingual and bilingual resources. Terminological and lexical resources are of various types, such as wordnets, electronic ...Ranka Stanković, Cvetana Krstev, Duško Vitas, Nikola Vulović, Olivera Kitanović.

The Usage of Various Lexical Resources and Tools to Improve the Performance of Web Search Engines
In this paper we present how resources and tools developed within the Human Language Technology Group at the University of Belgrade can be used for tuning queries before submitting them to a web search engine. We argue that the selection of words chosen for a query, which are of paramount importance for the quality of results obtained by the query, can be substantially improved by using various lexical resources, such as morphological dictionaries and wordnets. These dictionaries enable semantic ...LR web services, MultiWord Expressions & Collocations, Information Extraction, Information Retrieval... phrase structure is also based on the frequencies of compound structures that we have obtained from our existing dictionary of compounds.

A Fuzzy Expert Model for Availability Evaluation
Each technical system within itself carries the great potential danger of possible occurrence of failure and damages. Mining machines are characteristic by great investment values, costs of unplanned shutdowns, complex working conditions, and environment and workers hazards. Systematic monitoring of the mining machinery is of great importance for the management of the mining companies. Availability is the overall concept of quality of service. Includes information regard to operating state, an idle state, a standby state and shut down. The ......

Model inteligentnog sistema adaptivnog upravljanja procesom prerade rude
Ivana M. Jovanović (2016-01-13)U oblasti procesa prerade rude, flotacijska koncentracija predstavlja jednu od najznačajnijih i najčešće primenjivanih metoda separacije korisnih od nekorisnih minerala. Samim tim, veoma je važno osigurati uspešan rad flotacijskog postrojenja kroz dostizanje zadovoljavajućih tehno-ekonomskih pokazatelja. Cilj upravljanja procesom flotacijske koncentracije je upravo optimizacija kvaliteta i iskorišćenja korisne komponente u koncentratu uz maksimizaciju profita. Shodno tome, istraživanja na polju modelovanja i upravljanja ovim procesom zauzimaju značajno mesto u praksi kontolnog inženjenringa.Teorijska istraživanja u okviru doktorske disertacije obuhvatila su analizu položaja ...flotacijska koncentracija, modelovanje, upravljanje, inteligentni sistem, soft kompjuting, fazi logika, veštačke neuronske mreže...

Mikrobiološki diverzitet kiselog jezera Robule i uticaj jezerske vode na oksidaciju sulfidnih minerala
Srđan B. Stanković (2016-09-11)Jezero Robule, formirano u podnožju rudničke raskrivke Oštreljski planir (Rudnik bakra Bor), je nastalo kao posledica rudarskih aktivnosti. Mikrobiološki diverzitet ekstremno kiselog jezera Robule ispitivan je primenom kako klasičnih mikrobioloških metoda (svetlosna mikroskopija i kultivacija na selektivnim podlogama) tako i primenom savremene metode molekularne biologije (analiza polimorfizama terminalnih restrikcionih fragmenata; T-RFLP). Takođe, ispitivan je i potencijal i efikasnost jezerske vode u biološkom luženju mineralnog koncentrata, kao i u bioluženju uzoraka stare flotacijske jalovine Rudnika bakra Bor.Na osnovu dobijenih rezultata ...... 121 polymorphism (T-RFLP) analysis of 16S rRNA genes to characterise microbial communities, Applied Microbiology and Biotechnology 80: 365-380 97.
