Утечњени природни гас (УПГ) – технологија производње и регасификације
Јована Милетић (2024)У овом раду истраживање је обухватило сагледавање карактеристика утечњеног природног гаса као извора енергије и његове улоге у савременој расподели потрошње енергије на глобалном и европском нивоу. Проучени су елементи тржишта утечњеног природног гаса, сектори коришћења, транс-портне руте и количине испорука. Сагледан је пут природног гаса од лежишта до корисника преко утечњавања и транспорта у резервоарима, са посебним акцентом на технологијама производње и регасификације. Објашњено је пречишћавање сировог природног гаса ради уласка у процес утечњавања, процеси утешњавања и настојања ...утечњени природни гас, технологија производње и рега- сификације, транспорт, директно коришћење УПГ-а, могућност коришћења УПГ-а у Србији... va p- B I a J l j w u vp u I Z I k o u g g o l r m m v Z k i „ va j- 2 B I G G E D - · w r E m Ho r- : N I _ d a S — — _ m m ne u2 : N I I I K C I I H d i _ _ _ _ _ _ _ _ _ _ U M |L J a _ _ _ _ _ _ _ L I — MI Ocrano Cauka 2.1 – Cekmopu Kopuunetba ...

Towards Automatic Definition Extraction for Serbian
U radu su prikazani preliminarni rezultati automatske ekstrakcije kandidata za definicije rečnika iz nestrukturiranih tekstova na srpskom jeziku u cilju ubrzanja razvoja rečnika. Definicije u rečniku Srpske akademije nauka i umetnosti (SANU) korišćene su za modelovanje različitih tipova definicija (opisnih, gramatičkih, referentnih i sinonimskih) koje imaju različite sintaksičke i leksičke karakteristike. Korpus istraživanja sastoji se od 61.213 definicija imenica, koje su analizirane korišćenjem morfoloških e-rečnika i lokalnih gramatika implementiranih kao pretvarači konačnih stanja u paketu za obradu korpusa otvorenog ......

Fuzzy Model for Risk Assessment of Machinery Failures
The main goal of this research was the development of an algorithm for the implementation of negative risk parameters in a synthesis model for a risk level assessment for a specific machine used in the mining industry. Fuzzy sets and fuzzy logic theory, in combination with statistical methods, were applied to analyze the time picture state of the observed machine. Fuzzy logic is presented through fuzzy proposition and a fuzzy composition module. Using these tools, the symmetric position of the ...... taken for further analysis, µS,O,D j=1, . . . , 10 ,0, j = 1, . . . , 10. These combinations are identified as O, where O∈C.

Understanding the effect of synthesis and sintering temperature on the functional properties of barium titanate/cobalt ferrite composites
Marija Šuljagić, Aleksandar Kremenović, Ivan Petronijević, Adis Džunuzović, Miljana Mirković, Vladimir Pavlović, Ljubica Anđelković (2023)To investigate the effect of synthesis procedure and sintering temperature on the functional properties of perovskite/spinel ceramics, BaTiO3/CoFe2O4 composites were prepared by thermal decomposition, coprecipitation, and microemulsion method, and sintered at 1150°C and 1300°C. The phase composition and morphology of as-prepared powders as well as sintered ceramics were thoroughly examined by X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS). The dielectric and ferroelectric measurements were performed in detail.

Machine learning based landslide assessment of the Belgrade metropolitan area: Pixel resolution effects and a cross-scaling concept
Improvements of Machine Learning-based landslide prediction models can be made by optimizing scale, customizing training samples to provide sets with the best examples, feature selection, etc. Herein, a novel approach, named Cross-Scaling, is proposed that includes the mixing of training and testing set resolutions. Hypothetically, training on a coarser resolution dataset and testing the model on a finer resolution should help the algorithm to better generalize ambiguous examples of landslide classes and yield fewer over/underestimations in the model.

A Description of Morphological Features of Serbian: a Revision using Feature System Declaration
In this paper we discuss some well-known morphological descriptions used in various projects and applications (most notably MULTEXT-East and Unitex) and illustrate the encountered problems on Serbian. We have spotted four groups of problems: the lack of a value for an existing category, the lack of a category, the interdependence of values and categories lacking some description, and the lack of a support for some types of categories. At the same time, various descriptions often describe exactly the same ...... case depends on the animacy of the corresponding noun; for all other combinations of values for gender, number and case animacy is of no importance.

Selection of Artificial Lift Methods: A Brief Review and New Model Based on Fuzzy Logic
Miroslav Crnogorac, Miloš Tanasijević, Dušan Danilović, Vesna Karović Maričić, Branko Leković (2020)Artificial lift methods have applications in oil wells where oil production is no longer possible due to natural reservoir energy, so this necessary energy is added by introducing lift methods. In order to achieve optimum production, the selection of an artificial lift method is very important.
