Истраживањe могућности коришћења нискотемпературних извора топлоте за одрживи развој енергетике градова
Miodrag M. Grujić (2014-06-04)Одрживост је континуиран процес балансирања између животне средине, економске исоцијалне димензије, који се односи на системска побољшања животног окружења.Енергија се налази међу покретачима одрживог развоја везано за потребу за повећањесоцијалног благостања, његову кључну улогу у економском развоју и утицај на животнусредину. Урбане зоне, као центри потреба за енергијом и емисија угљеника, пружајузначајне могућности за промоцију одрживости енергетског система заједнице.Планирање нових енергетских капацитета, у складу са принципима одрживог развоја,обухвата спровођење политике повећања енергетске ефикасности и увођења обновљивихизвора енергије.

Đorđije M. Božović (2023)Predmet istraživanja doktorske disertacije su bunari sa horizontalnim drenovima beogradskog izvorišta podzemnih voda, drugog najvećeg izvorišta ovog tipa na svetu, čiji je režim rada opterećen procesima intenzivnog starenja prisutnog od samog početka formiranja izvorišta, početkom 1950‒ih godina. Istraživanja sprovedena u okviru izrade disertacije su imala za cilj definisanje nove metodologije izučavanja procesa mehaničkog i biohemijskog kolmiranja drenova izradom detaljnih 3D numeričkih hidrodinamičkih modela, upotrebom postojećih, dostupnih i široko rasprostranjenih računarskih programa.

On the distribution modulo 1 of the sum of powers of a Salem number
Dragan Stankov (2016)It is well known that the sequence of powers of a Salem number θ, modulo 1, is dense in the unit interval, but is not uniformly distributed. Generalizing a result of Dupain, we determine, explicitly, the repartition function of the sequence , where P is a polynomial with integer coefficients and θ is quartic. Also, we consider some examples to illustrate the method of determination.Algebraic integer, the house of algebraic integer, maximal modulus, reciprocal polynomial, primitive polynomial, Schinzel-Zassenhaus conjecture, Mahler measure, method of least squares, cyclotomic polynomialsDragan Stankov.

A Knowledge-Based Approach to Mine Ventilation Planning in Yugoslav Mining Practice
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.

Numerical modeling of Selanac debris flow propagation using SPH code
The Selanac debris flow is a very huge event triggered after extreme rainfall caused by Cyclone Tamara activity in the Republic of Serbia in May 2014. The Selanac case study was already modelling in different programs using Voellmy rheology assumptions like RAMMS software. In this paper research are focusing particularly on the process of debris flowing from initiation zone to main deposition area using Geoflow SPH two-phase model considering frictional rheology law. Main rheological parameters are back-calculated using also ...... B. and Samardžić-Petrović, M.

A fuzzy-based decision support model for effectiveness evaluation - a case study of examination of bulldozers
Effectiveness evaluation is one of the basic components of engineering asset management and maintenance engineering in general. Effectiveness is an overall concept representing a measurement of quality of service level for the analyzed engineering system. This concept contains a series of partial indicators relating to time in operation and time for maintenance activities, as well as functional properties of the system. This article describes the analysis and structuring of partial indicators, as well as the development of a model ...Miloš Tanasijević, Predrag Jovančić, Dejan Ivezić, Uglješa Bugarić, Radiša Đurić.

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.... S+p m+f En Hu PL Pl S+p mo+mr+mz+f+n Hr S+p m+f+n Bg S+p m+f+n Sr S+p+w m+f+n Table 2.

Одређивање резерви нафтног лежишта „Х“ методом материјал баланса
Александра Петровић (2024)Метода материјалног баланса је кључна техника у процени резерви нафте и гаса у лежиштима која омогућава системско прорачунавање доступних резерви. Циљ ове методе је да се прецизно израчунају количине флуида у лежишту на основу доступних PVT података, података о лежишту и производњи. Резултати примене методе материјалног баланса показују да је она ефикасна у пружању кавнтитативних процена, међутим њена тачност зависи од квалитета улазних података. Метода материјалног баланса пружа основу за процену резерви, али може бити подложна грешкама због непрецизности ......
