Napoved mehanskih lastnosti jekel pri kaljenju na osnovi akustične emisije
Bor Mojškerc, Janez Grum, Tomaž Kek
Doktorska disertacija
Oznake: neporušne preiskave;akustična emisija;analiza signalov;kaljenje;mehanske lastnosti;
Direktno potopno kaljenje se uporablja za izboljšanje mehanskih lastnosti različnih jeklenih strojnih delov. Postopek poteka na način, da se obdelovance segreje na temperaturo avstenitizacije in nato ohladi z gašenjem v gasilnem sredstvu. V okviru disertacije je razvita neporušna metoda nadzora kalj ...

Experimental characterisation of laser surface remelting via acoustic emission wavelet decomposition
Bor Mojškerc, Dunja Ravnikar, Roman Šturm
Izvirni znanstveni članek
Oznake: lasers;surface remelting;acoustic emission;signal processing;wavelet;
This paper presents a novel technique of monitoring laser surface remelting (LSR) via measurements of process generated acoustic emission (AE). The LSR conditions include a variable laser power level and an ambient air or argon 5.0 inert gas atmosphere. The microstructure and microhardness of the re ...

Investigation of laser surface remelting supported by acoustic emission analysis and machine learning
Dunja Ravnikar, Bor Mojškerc, Roman Šturm
Izvirni znanstveni članek
Oznake: laser surface remelting;microstructure;acoustic emission;machine learning;
In the present work, laser surface remelting (LSR) was carried out on C45 carbon steel using an Nd:YAG pulse laser. The effect of process parameters, such as different laser pulse durations and the absence or presence of a graphite absorber, on the microstructure, remelting depth, and microhardness ...

Fatigue and wear performance of bioepoxy vacuum-infused and autoclave-cured E-glass fiber reinforced polymer composite gears in mesh with a steel pinion
Bor Mojškerc, Zoran Bergant, Roman Šturm, Nikola Vukašinović
Izvirni znanstveni članek
Oznake: composites;glass fibers;gears;fatigue;wear;
Polymer composite gears are under investigation as a promising solution to mitigate the performance gap between polymer and metal gears. The study presented in this paper evaluates the fatigue and wear performance of E-glass fiber reinforced polymer composite gears. The E-glass fibers are vacuum inf ...

Oznake: polimerni zobniki;utrujanje;lom;odpoved;razpoka;
V sklopu raziskave so bili analizirani različni parametri, ki vplivajo na rast razpoke v korenu zoba in posledično na življenjsko dobo zobnika. V prvem koraku je bila z uporabo metode končnih elementov preverjena ustreznost metode 30° tangente, ki jo za določanje kritičnega prereza zoba uporablja st ...

Image-based monitoring of material emissions for wear characterization of laminated polymer composite gears
Aleš Durjava, Bor Mojškerc, Zoran Bergant, Nikola Vukašinović
Izvirni znanstveni članek
Oznake: wear;gears;composites;microplastics;particles;image analysis;
This work presents a computer vision image-based methodology for quantitative wear particle diagnostics in polymer composite gear systems. Conventional monitoring techniques typically provide limited information on the morphology and size distribution of the particles, restricting their diagnostic c ...

ǂAn ǂopen-label randomized controlled trial comparing the efficacy and safety of a 7-day triple therapy with bismuth versus 14-day standard triple therapy for Helicobacter pylori eradication in children and adolescents
Anja Šterbenc, Bor Vratanar, Eva Miler Mojškerc, Matjaž Homan
Izvirni znanstveni članek
Oznake: Helicobacter pylori;bismuth;children;eradication;treatment;
Background: To achieve eradication rates > 90%, the ESPGHAN/NASPGHAN guidelines for pediatric Helicobacter pylori in-fection recommend tailored antimicrobial therapy using sufficiently high doses over 10–14 days. However, prolonged treatmentoften leads to suboptimal compliance in children, which is ...
