Strategic Environmental Assessment in the Application of Preventive Protection for Wind Farm Noise—Case Study: Maestrale Ring Wind Farm
Determining the spatial position of wind turbines is the initial and most important phase in the development of a wind farm project. In this sensitive phase, all potential problems that may arise in the later stages of project development should be prevented by means of spatial and urban planning instruments. This makes it possible to achieve maximum use of the potential of wind in a particular space and, thus, fulfil the technical and economic requirements of the project while ...Energija,energetski inženjering i elektroenergetska tehnologija,obnovljivi izvori energije, održivost i životna sredina,električni i elektronski inženjering,kontrola i optimizacija,inženjering... to the Criteria from Table 2.) of the Impact Explanation Unit 1-Čantavir east (46 wind turbines) T o r ed u ce e xp o su re o f th e p o p u la ti o n t o i n cr ea se d n o is e le v el s 0 In units 1 and 2 no increase in the level of noise above LVNI is expected ...

The series of Fe3−xYxO4 (x=0.00, 0.042 and 0.084, labeled as Y00, Y05 and Y10, respectively) was synthesized using co-precipitation followed by microwave-hydrothermal treatment (MW) at 200°C. With increase of yttrium content(xvalue), both the morphological inhomogeneity of the samples and the fraction of spinel nanorods as compared to spinel pseudospherical particles increased.

Definisanje strukturnih odnosa primenom postupka horizontalni gradijent
Različiti postupci matematičkih transformacija se mogu primeniti na gravimetrijskim i magne tometrijskim podacima, kako bi se na istražnom terenu definisali strukturno-tektonski odnosi. U radu su prikazani rezultati dobijeni korišćenjem postupka horizontalni gradijent i ukupni horizontalni gradijent na gravimetrisjkim podacima. Navedeni postupci su pomogli da se detektuju kontakti sa velikim padnim uglom (vertikalni ili subvertikalni kontakti), koji se mogu interpretirati kao rasedi.

Uticaj starosti i sastava komunalnog otpada na zbijanje
Bez obzira na mogućnost da se komunalni otpad koristi kao sirovina, u Srbiji je i dalje osnovni vid odlaganja na komunalne deponije. Iako je odlaganje na deponije prema hijerarhiji otpada najnepovoljnije rešenje, u odnosu na ranije formirana smetilišta i neuređene deponije, ipak se sistemski dolazi do prikupljanja podataka, što se može smatrati poboljšanjem prakse.

Machine Learning and Deep Neural Network-Based Lemmatization and Morphosyntactic Tagging for Serbian
The training of new tagger models for Serbian is primarily motivated by the enhancement of the existing tagset with the grammatical category of a gender. The harmonization of resources that were manually annotated within different projects over a long period of time was an important task, enabled by the development of tools that support partial automation. The supporting tools take into account different taggers and tagsets.

Damage quantification of built stone on Dark Gate (Belgrade, Serbia): sample of damage index application for decay rate evaluation
The Dark Gate is the monument of culture, part of the cultural and historical complex of the Belgrade Fortress. It is constructed of limestone blocks that after 270 years of exposure to environmental conditions and different anthropogenic influences show wide ranges of decay forms. During 2007, detail registration of all built limestone microfacies and weathering forms was done using tools of monument mapping.

INVENTS: a hybrid system for subsurface ventilation analysis
Ventilation system analysis is a complex process based on the calculation and analysis of numerous parameters. These problems can be successfully solved by the SimVent numerical package, but a full understanding and use of the obtained results require the involvement of an experienced specialist in the ventilation field. The solution was found in the creation of a hybrid system INVENTS, whose knowledge base represents a formalization of the expert knowledge in the mine ventilation field. In this paper we ......

A WordNet Ontology in Improving Searches of Digital Dialect Dictionary
In this paper, we present a method for automatic generation of a digital resource, which connects all indirect synonyms of a dialect term to all indirect synonyms of a corresponding term in the standard language, aiming to improve the search of a digital dialect dictionary. The method uses SWRL rules defined in the Serbian WordNet ontology to identify sets of synonymous words. It also uses e-dictionaries to produce correct lemmas in standard language that users usually employ in searches. ...... to the observed one. odobriti (grant) < ч“оћч(“ вупогу“ “ i ; dozvoliti (allovv) / uvesti (let in) .'/– 1 i 1 7 1 7 ! verb_group и и риз т (admit) _/' – д Qo__/ „ 1 ~ пИ imati poverenja (trust) : 7 . „ : р и _ Р и а зупо“ ашогпгоман (ашћог ге) dozvoliti (permit, let) — а /5„ ...

Opremanje bušotine X zavojnom pumpom
Milan Filipović (2024)Ovaj rad se bavi osnovnim pojmovima i karakteristikama zavojnih pumpi.Prikazan je sklop zavojnih pumpi i njena prateća oprema. Objašnjen je princip rada zavojnih pumpi kao i uloga svakog mašinskog elementa koji se nalazi u pumpi. Razmotrene su prednosti i nedostaci primene ovih primarnih mehaničkih metoda eksploatacije ugljovodonika. Dat je uvid u inovativna rešenja problematike primene zavojnih pumpi. Na konkretnom primeru bušotine X su prikazani problemi kao i rešenja primene ovih primarnih mehaničkih metoda u praksi. Napravljena je detaljna analiza ...... pumpe, jeste I sprečavanje nekontrolisanog izlivanja kroz spoj bušotinske glave i glatke šipke.
