  • Testing the energy value of different types of coal by the method of active thermography

    Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Predrag Jovančić, Dragutin Jovković (2020)
    In this paper, coal thermograms are presented and analyzed in order to determine their energy value. Two types of coal of different categories, brown and lignite, were selected for active thermographic imaging. The tested coal samples were processed before measurement so that they are similar in dimensions and have two plane-parallel smooth surfaces. The test samples were "primarily" heated under the same conditions and the process of their cooling was monitored by a thermal camera. "Then" they were cooled ...

  • Primena termografije u rudarstvu

    Stevan Đenadić, Vesna Damnjanović, Predrag Jovančić, Dragan Ignjatović, Dragutin Jovković, Filip Miletić (2019)
    Danas, gotovo da nema oblasti u nauci i tehnici u kojoj se Infracrvena termografija ne primenjuje kao metoda za lociranje i praćenje zagrejanih objekata ili tela, beskontaktnu procenu temperature površina, i nedestruktivno ispitivanje materijala. U radu su prikazane mogućnosti i perspektive primene ove metode u oblasti rudarstva.

  • Mogućnost infracrvene termografije pri detekciji štetnih gasova

    Stevan Đenadić, Vesna Damnjanović, Predrag Jovančić, Dragutin Jovković (2021)
    Curenje pojedinih gasova je opasnost koja može da izazove velike nezgode. Često je praćeno požarima i eksplozijama koji za posledicu mogu da imaju kako ljudske povrede, tako i štetan uticaj na ekologiju i ekonomiju. Da bi se izbegle takve situacije, preventivna inspekcija je od presudne važnosti. Curenje većine gasova se ne može uočiti golim okom a za otkrivanje i procenu stepena curenja može se koristiti tehnologija toplotnog snimanja (infracrvena termografija). U datom radu predstavljene su mogućnosti i ograničenja primene ...

  • Analiza uporednog praćenja temperature površine ohlađenih materijala pri njihovom zagrevanju do ambijentalne temperature

    Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Katarina Nestorović (2021)
    U datom eksperimentalnom radu su termografskim metodama ispitivane termofizičke karakteristike različitih materijala. Za ispitivanja su izabrani mesingani niovčić, ugalj i pelet, jer imaju različita termoizolaciona svojstava i različito stanje površine. Uzorci su najpre hlađeni, a zatim je njihovo zagrevanje na sobnoj temperaturi praćeno termalnom kamerom. U drugom delu eksperimenta, korišćena je impulsna termografija, a zagrevanje površine uzoraka vršeno je svetlosnom pobudom.

  • Tracking of the temporal dependency of fading of the human footprint temperature contrast

    Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Darko Vasiljević, Danica Pavlović (2021)
    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]. The paper presents the results of experiments that suggest another possible use of ...
