Проширивање мреже пловних путева Републике Србије у функцији одбране земље
Мрежу пловних путева Републике Србије чини мрежа међународних и међудржавних пловних путева. Међународне пловне путеве чине реке Дунав, Сава, Колубара, Дрина, Канал Дунав-Тиса-Дунав (Д-Т-Д) „Нови Сад – Савино село“ и Беочински рукавац – канал, док међудржавни пловни пут на коме важи међународни режим пловидбе чини река Тиса. Поред наведених пловних путева који већим делом обухватају територију Аутономне покрајине Војводине, Република Србија има потенцијал проширења мреже пловних путева и у централном делу Србије пре свега у Поморављу.

Punctuated, episodic magmatism and mineralization of the Rogozna skarn-hosted Au-Zn-Pb-Cu deposits revealed through high-precision U-Pb zircon geochronology
The subvolcanic regions of magmatic centers are commonly associated with alteration, mineralization, and economic ore deposits, however the duration and frequency of mineralizing pulses within the overall lifespan of these centers can be poorly defined. Therefore, models for the formation of mineral systems require more highprecision geochronology data to refine their evolutionary models. Rogozna Mountain and its eponymous magmatic complex, located in SW Serbia, hosts multiple base metal deposits associated with variable rock types and structural expressions and serves as a natural laboratory to ...Skarnovska mineralizacija, Magmatsko-hidrothermalni sistemi, Subvulcanske intruzije, geohronologija na cirkonima, CA-ID-TIMSSean P.

Determination of parameters for wet grinding of phosphates in a laboratory ball mill and classification in a hydrocyclone
Компанија Elixir Прахово у свом производном процесу користи суво млевење сировог фосфата за своју производњу. Међутим, због повећане влаге у сировом фосфату која изазива потешкоће у фази сувог млевења, разматра се могућност увођења мокрог млевења у индустријском постројењу у Прахову. Влага улазног сировог фосфата варира од барже до барже, и креће се у границама 5-10% H2O, што је јако високо за процес сувог млевења а ствара одређене проблеме и на транспортном систему (систем редлерских транспортери). За сагледавање могућности мокрог млевења ...Predrag Lazić, Đurica Nikšić, Vladan Živković, Nemanja Todorović.

Serbian ELTeC Sub-Collection in Wikidata
This paper presents an example of integration of Wikidata with digital libraries and external systems, as well as some best practices for speeding up the process of data preparation and import to Wikidata, on the use case of SrpELTeC, Serbian subcollection of the ELTeC multilingual collection (European Literary Text Collection). After preliminary work on the manual Wikidata population with SrpELTeC novels, the goal was to automate the process of preparing and importing information, so different solutions were analysed and ...Milica Ikonić Nešić, Ranka Stanković, Biljana Rujević.

Утицај реактивираних раседа на развој крашког процеса: примери из Карпато-балканида источне Србије
Ана Младеновић (2022)Carpatho-Balkanides represent part of the complex Dinaric-Carpatho-Balkan orogenic system, that geomorphologically dominates the central part of the Balkan peninsula. The existence of this orogenic system is a result of closure of the Neotethys ocean and subsequent convergence of the Adriatic microplate and the Eurasian continent, that has been still active in the recent times. Such geodynamic characteristics conditioned complex tectonic structures, multiply reactivated during Late Cretaceous and Cenozoic. The main aim of this research is to determine impact of ...Ана Младеновић.

History of the development of the hydrodynamic model of the open pit mine “Drmno”, Serbia
With the creation of a hydrodynamic model, the need for it usually ceases until some next moment when the model needs to be updated and used for the set task for the necessary project documentation or dedicated studies. It is relatively rare that almost every year the model is improved and used for forecast calculations.

Analysis and visualization of geophysical well-logging data from closely spaced boreholes
Geophysical logging measurements for determining the condition of the rock mass on the dam profile and locating the predisposed directions of water circulation and loss from the reservoir were conducted in four boreholes distributed at a close distance. The survey was carried out in a typical karst terrain, which is an additional challenge for defining the geological model, especially in terms of water retention. That kind of data set provides an excellent opportunity for a new approach to analysis ...Branislav Sretković, Ivana Vasiljević, Dimitry Sidorov - Biryukov.

Eigensensitivity and structural optimization with accent on the repeated frequencies
Sensitivity analysis is the study of changes in system response with respect to design parameters. It is being used in a variety of engineering disciplines ranging from automatic control theory to the analysis of large-scale physiological systems. Some of areas where sensitivity analysis has been applied include: development of insensitive control systems, use in gradient based mathematical programming methods and approximation of system response to change in a system parameter, assessment of design changes on system performance. Eigensensitivity analysis ...Nataša Trišović, Wei Li, Nikola Mladenović, Olivera Jeremić, Ines Grozdanović, Ana Petrović.
