Tracking of the temporal dependency of fading of the human footprint temperature contrast
In certain situations, it is extremely important to determine the exact time “someone” entered or crossed the forbidden zone of a military or strategic installation, a red zone of radioactive, chemical, or biological contamination, a bank or similar structure. Standard security measures include ordinary video surveillance using cameras that operate in the visible range of the electromagnetic spectrum, as well commercial thermal imaging cameras [1, 2].

Analiza primenjenih metoda za transport parafinske nafte
Dunja Milojević (2024)Sadržaj parafina u nafti ima dominantan uticaj na svojstva parafinskih nafti. Taloženje parafina, odnosno taloženje čvrstih čestica parafinskog voska, predstavlja ozbiljan globalni problem tokom proizvodnje i transporta sirove nafte. Samo taloženje voska zavisi od termodinamičkih faktora, poput temperature, pritiska i sastava nafte. Transport nafte cevovodima je uobičajeni proces transporta u naftnoj industriji. Kada prilikom cevovodnog transporta parafinske sirove nafte, dođe do prekida protoka i hlađenja nafte ispod temperature stinjavanja, parafini će kristalisati, pri čemu će doći do, geliranja celokupne transportovane ......

Production of morphological dictionaries of multi-word units using a multipurpose tool
The development of a comprehensive morphological dictionary of multi-word units for Serbian is a very demanding task, due to the complexity of Serbian morphology. Manual production of such a dictionary proved to be extremely time-consuming. In this paper we present a procedure that automatically produces dictionary lemmas for a given list of multi-word units. To accomplish this task the procedure relies on data in e-dictionaries of Serbian simple words, which are already well developed.

Laboratory testing of fly ash
Fly ash is one of the most common waste materials created by burning of coal. It is composed of smaller particles, consisting mainly of aluminosilicate glass, mullite and quartz, which are collected by electrostatic separators (filter) of gaseous products arising from the combustion of coal.

Energetska tranzicija u domaćinstvima: analiza usaglašenosti Srbije sa paketom „Čista energija za sve Evropljane“ / Energy Transition in Households: Analysis of Serbia’s Compliance with the „Clean Energy for All Europeans“ Package
Zahvaljujući svojoj složenosti i heterogenosti, sektor domaćinstva predstavlja neizostavnu tačku u politikama energetske tranzicije. U Evropskoj uniji, potrošnja energije u domaćinstvima čini oko 26% finalne potrošnje energije, dok u Srbiji ovaj sektor ima najveći udeo u finalnoj potrošnji, što čini oko trećinu finalne potrošnje. Primenom mera energetske efikasnosti moguće je ostvariti značajne energetske uštede, što zajedno sa smanjenjem i supstitucijom upotrebe fosilnih goriva vodi manjem doprinosu klimatskim promenama i značajnom smanjenju zagađenja vazduha.

Моделирање дисперзије прашине у фази одлагања флотацијске јаловине у руднику “Шупља стијена”
Вања Живановић (2024)Рударство, као једна од кључних индустрија у многим земљама света игра важну улогу у стварању економске вредности али истовремено и велики притисак на животну средину. Процеси експлоатације и обраде руде често укључују употребу разних хемикалија, што може изазвати загађење земљишта, воде и ваздуха.

Adaptive neuro-fuzzy prediction of operation of the bucket wheel drive based on wear of cutting elements
The capacity of the rotor excavator depends largely on the operation of the subsystem for digging. There is a great contribution to the correct and sharp teeth when the capacity is the highest. In the function of time, the teeth become clogged due to abrasive wear, or changes in their geometric shape.

Using English Baits to Catch Serbian Multi-Word Terminology
