Digitalni dvojček elektronskega sistema

As the market of electrified vehicles is rapidly growing, the requirements for new products are also increasing, meaning the required development and production times are getting increasingly shorter. Therefore, the major interest in current active research is how to optimize the development process. Within this master’s thesis, we developed the base framework for a digital twin for wiring harness development and cross section optimization. It allows engineering teams to develop a digital replica of the desired physical system, which can be the basis for further review and optimization analyses, already at the development stage.Optimizacija razvojnega procesa je trenutno eden izmed glavnih interesov trenutnih raziskav v mnogih industrijah. V okviru tega magistrskega dela smo razvili osnovno programsko okolje za izdelavo digitalnega dvojčka, ki ga lahko uporabimo med razvojem kabelskih snopov in optimizacijo prečnega preseka vodnikov. Ta omogoča inženirskim ekipam, da že v fazi razvoja razvijejo digitalno repliko želenega fizičnega sistema, ki je lahko osnova za nadaljnje preglede in optimizacijske analize

The design of composite concrete bed for cnc machine tool

Magistrsko delo Zasnova kompozitne betonske postelje za CNC-obdelovalni stroj vsebuje zasnovo, potek izdelave in stroškovno analizo kompozitne betonske postelje. Kompozitna betonska postelja je namenjena za obdelovanje aluminija na štiri ali pet osnih CNC-obdelovalni strojih. Zaradi visokih obdelovalnih hitrosti so se pri postelji pojavili določeni problemi kot na primer vibracije in hrup pri obdelavi. Rešitev smo našli v zalivanju profilov z mineralnim betonom in protihrupnimi paneli. Kompozitna betonska postelja je varjena konstrukcija. Izdelana je iz jeklenih profilov, ki so naknadno zaliti z mineralnim betonom.The master\u27s thesis, The Design of a composite concrete bed for a CNC-machining center, contains the design, manufacturing process and cost analysis of a composite concrete bed. The composite concrete bed is intended for processing aluminum on four or five axis CNC-machining machines. Due the high machining speeds, certain problems arose with the bed, such as vibration and machining noise. For that we found a solution, such as pouring profiles with mineral concrete and anti-noise panels. Composite concrete bed is a welded construction, made of steel profiles, which are later filled with mineral concrete

Automation of co2 emptying machine

Diplomsko zaključno delo opisuje potek gradnje avtomatiziranega stroja za praznjenje CO2 jeklenk. Gre za rotacijski stroj, gnan s pomočjo servo pogona, ki s pomočjo pnevmatskih cilindrov izprazni jeklenke ter jih preda polnilnemu stroju. Jeklenke, ki jih stroj ne uspe izprazniti v prvem ciklu, ter ki pridejo v stroj s prenizkim tlakom, se na izhodnem traku s pnevmatskim cilindrom izvržejo. Stroj se dejansko obnaša kot neke vrste stroj inšpektor, saj je tako omogočen ponoven proces visokotlačnega polnjenja s plinom CO2. Izpraznjen CO2 se skozi praznilni ventil in odzračevalni kanal odzrači s pomočjo ventilatorja. Proces je opisan od začetnih pomembnih konstrukcijskih lastnosti pa vse do njegove elektro-programske rešitve.The diploma thesis describes the construction process of an automated CO2 cylinder emptying machine. It is a servo-driven rotary machine that empties the cylinders using pneumatic cylinders and passes them to a filling machine. Cylinders that fail to be emptied in the first cycle and that enter the machine at too low – pressure, are ejected at the pneumatic cylinder outlet conveyor. The machine effectively behaves as a kind of machine inspector, as this allows the high-pressure CO2 filling process to be repeated. The discharged CO2 is vented through the discharge valve and the venting duct by means of a fan. The process is described from the initial important design features to the electrical and software solution of the process

Nanosateliti zaradi kompaktnih dimenzij, nizke mase in stroškovne učinkovitosti postajajo vse bolj dostopni širšemu krogu organizacij in raziskovalcev. Z natančnim merjenjem zemeljskega magnetnega polja prispevajo k raziskovanju geomagnetnih pojavov in nadzoru položaja. Izziv predstavlja vpliv elektromagnetnega polja nanosatelita na odčitek magnetometra. Magistrsko delo opisuje načrtovanje in izdelavo prototipa namestitvenega mehanizma magnetometra v obliki podsistema, skladnega s standardom PC104. Podsistem je mogoče integrirati v strukturo nanosatelitov in omogoča namestitev magnetometra na razdaljo, večjo od 1 m od strukture satelita. Tako zmanjšamo vpliv elektromagnetnega polja satelita na zanemarljivo raven. V delu so predstavljeni rezultati več meritev za ovrednotenje delovanja izdelanega podsistema.Nanosatellites, characterized by compact dimensions, low mass, and cost-effectiveness, are becoming increasingly accessible to a wider range of organizations and researchers.

The thesis presents measurement results evaluating the subsystem\u27s performance

Transportation of railway transport management at Pragersko station

Digitalizacija in avtomatizacija prinašata pomembne spremembe tudi v železniškem prometu, kjer vplivata na organizacijo dela in učinkovitost sistema. Diplomsko delo se osredotoča na primer železniške postaje Pragersko, ki je bila v zadnjih letih celovito modernizirana. Diplomsko delo raziskuje vpliv sprememb pri uvajanju sodobnih informacijskih sistemov ILTIS, GSM-R, SCADE, PIS in ETCS na delo prometnika oziroma progovnega prometnika ter na organizacijo vodenja prometa. Pri tem so bili uporabljeni opisna, primerjalna in analitična metoda, študija primera ter polstrukturirani intervju z zaposlenimi. Rezultati kažejo, da je digitalizacija povečala pretočnost prog in učinkovitost dela glede na prejšnje stanje, obenem pa združila naloge več prometnikov v eno delovno mesto progovnega prometnika. To pomeni večjo odgovornost, večjo psihično obremenitev in potrebo po višji ravni strokovnega znanja. Kljub avtomatizaciji ostaja človeški dejavnik ključen za zagotavljanje varnosti in zanesljivosti železniškega prometa.Digitalization and automation have introduced significant changes in railway traffic, influencing both work organization and system efficiency. This thesis focuses on the case of Pragersko railway station, which has undergone extensive modernization in recent years. The research analyses the impact of modern information systems ILTIS, GSM-R, SCADA, PIS, ETCS, on the work of the dispatcher and line dispatcher, as well as on the organization of traffic management. A descriptive, comparative and analytical method was applied, combined with a case study and structured interviews with employees. The results show that digitalization has increased line capacity and work efficiency to the previous state), while consolidating the tasks of several dispatchers into a single line dispatcher position. This has resulted in greater responsibility, higher psychological workload, and the need for advanced professional expertise. Despite automation, the human factor remains crucial for ensuring the safety and reliability of railway traffic

Simulation of a production process using the open-source software blender

V diplomskem delu smo raziskali, kako se odprtokodni program Blender uporablja za simulacijo proizvodnih procesov z namenom usposabljanja industrijskih delavcev. Glavni cilj dela je bil izdelati 3D-animacijo, ki je ponazarjala realističen proizvodni proces in služila kot učni pripomoček pri uvajanju zaposlenih. S tem smo prikazali, kako lahko digitalne 3D-simulacije prispevajo k učinkovitejšemu, varnejšemu in bolj stroškovno ugodnemu izobraževanju zaposlenih. V teoretičnem delu smo predstavili ključne tehnologije, koncepte in razvoj digitalnih orodij za industrijsko usposabljanje, v praktičnem delu pa smo v programu Blender zasnovali in izdelali 3D-model proizvodne linije z animacijo ključnih korakov sestave. Animacija omogoča jasno vizualizacijo posameznih postopkov in varno učenje brez fizične izpostavljenosti strojem ali nevarnim okoljem. Dodatno smo izvedli raziskavo, s katero smo preverili uporabnost ustvarjene animacije v primerjavi s klasično dokumentacijo. Rezultati so pokazali, da 3D-simulacije pozitivno vplivajo na razumevanje delovnih nalog, povečujejo ohranjeno znanje in zmanjšujejo število napak. Na podlagi ugotovitev smo pripravili priporočila za uvajanje tovrstnih rešitev v industrijsko izobraževanje in smernice za izboljšanje digitalnih vsebin s pomočjo odprtokodnih orodij.In this thesis, we explored how the open-source software Blender was used to simulate manufacturing processes for the purpose of training industrial workers. The main objective of the thesis was to create a 3D animation that represented a realistic production process and served as an educational tool for employee onboarding. Through this, we demonstrated how digital 3D simulations could contribute to more efficient, safer, and more cost-effective employee training. In the theoretical part, we presented key technologies, concepts, and the development of digital tools for industrial training, while in the practical part, we designed and created a 3D model of a production line in Blender, including animations of the key assembly steps. The animation provided a clear visualization of individual procedures and enabled safe learning without physical exposure to machinery or hazardous environments. Additionally, we conducted a study to evaluate the usefulness of the created animation in comparison with traditional documentation. The results showed that 3D simulations had a positive effect on understanding work tasks, increased knowledge retention, and reduced the number of errors. Based on these findings, we prepared recommendations for the implementation of such solutions in industrial education and guidelines for improving digital learning materials using open-source tools

CONNECTION BETWEEN TRUST IN INFLUENCERS AND CUSTUMER PURCHASE DECISIONS

V diplomskem delu preučujemo povezavo med zaupanjem v vplivneže in nakupnimi odločitvami odjemalcev. Družbena omrežja so postala ključna platforma za oglaševanje, vplivneži pa pomembni posredniki med blagovnimi znamkami in odjemalci. Njihova moč temelji na občutku avtentičnosti in bližine, pri čemer je zaupanje odločilen dejavnik uspešnosti priporočil. Diplomsko delo je sestavljeno iz teoretičnega in empiričnega dela. V teoretičnem delu smo opredelili odjemalce, predstavili izbrane teorije njihovega vedenja ter opisali vlogo družbenih omrežij pri oblikovanju potrošniškega vedenja. Poseben poudarek smo namenili vplivnežem in dejavnikom zaupanja, kot so iskrenost, zanesljivost, doslednost, strokovnost in transparentnost, ki bistveno vplivajo na sprejemanje njihovih priporočil. V empiričnem delu smo s spletnim anketnim vprašalnikom analizirali vpliv zaupanja na nakupne odločitve. Rezultati kažejo, da odjemalci, ki bolj zaupajo vplivnežem, pogosteje sledijo njihovim priporočilom in opravijo nakup. Najpomembnejši dejavniki zaupanja so se izkazali zanesljivost, iskrenost in odzivnost vplivnežev. Ugotovljeno je bilo tudi, da so mlajši odjemalci dovzetnejši za vpliv vplivnežev, medtem ko starejši izražajo večjo mero previdnosti. Ugotovitve potrjujejo, da je zaupanje ključni element uspešnega vplivnostnega marketinga, saj neposredno oblikuje odnos med sledilci in blagovno znamko ter vpliva na odjemalčeve odločitve.This thesis examines the relationship between trust in influencers and consumers’ purchasing decisions. Social media has become a key platform for advertising, while influencers serve as important intermediaries between brands and consumers. Their power is based on a sense of authenticity and closeness, with trust being a decisive factor in the effectiveness of their recommendations. The thesis consists of both theoretical and empirical parts. In the theoretical section, we defined consumers, presented selected theories of their behavior, and described the role of social media in shaping consumer behavior. Special attention was given to influencers and the trust factors—such as honesty, reliability, consistency, expertise, and transparency—that significantly affect the acceptance of their recommendations. In the empirical part, the influence of trust on purchasing decisions was analyzed through an online survey questionnaire. The results show that consumers who trust influencers are more likely to follow their recommendations and make purchases. The most important trust factors were found to be the influencers’ reliability, honesty, and responsiveness. It was also observed that younger consumers are more susceptible to influence of influencers, while older consumers tend to exercise greater caution. The findings confirm that trust is a key element of successful influencer marketing, as it directly shapes the relationship between followers and the brand and influences consumer decisions

Prevention of healthcare-associated infections in preterm infants in the incubator

Uvod: Nedonošenčki v inkubatorju imajo zaradi nezrelega imunskega sistema in pogostih invazivnih posegov povečano tveganje za okužbe, povezane z zdravstveno oskrbo. Namen zaključnega dela je proučiti ukrepe, s katerimi zdravstveni delavci zmanjšujejo pojavnost okužb, povezanih z zdravstveno oskrbo, pri nedonošenčkih, nameščenih v inkubatorju. Metode: Izveden je bil pregled znanstvene in strokovne literature, ki smo jo iskali v podatkovnih bazah CINAHL Ultimate, PubMed in ScienceDirect. Potek vključevanja in izključevanja raziskav smo ponazorili s PRISMA diagramom. Izbrane raziskave smo zbrali v evalvacijsko tabelo, jih ovrednotili glede na raven dokazov ter izvedli tematsko analizo. Rezultati: Izmed 436 zadetkov smo jih v končno analizo vključili osem. Rezultati kažejo, da so preventivni ukrepi za preprečevanje okužb, povezanih z zdravstveno oskrbo, pri nedonošenčkih v inkubatorju kompleksen proces, pri katerem imajo ključno vlogo štiri področja: organizacijske ovire pri izvajanju ukrepov, usposabljanje in izobraževanje zdravstvenega osebja, dezinfekcija inkubatorjev, prav tako pa je pomembna vloga staršev in vodstva pri preprečevanju okužb, povezanih z zdravstveno oskrbo. Razprava in zaključek: Okužbe, povezane z zdravstveno oskrbo, povzročajo zaplete, podaljšujejo hospitalizacijo in povečujejo tveganje za smrtnost, raziskave pa potrjujejo, da kljub napredku še vedno predstavljajo velik problem. Prav zato je za varno obravnavo nedonošenčkov v inkubatorju ključnega pomena dosledno izvajanje preventivnih ukrepov.Introduction: Premature infants in incubators are at increased risk of healthcare-associated infections due to their immature immune system and frequent invasive procedures. The purpose of this thesis is to examine the measures healthcare professionals use to reduce the incidence of healthcare-associated infections in premature infants placed in incubators. Methods: A review of scientific and professional literature was conducted, which we searched in the CINAHL Ultimate, PubMed, and ScienceDirect databases. The process of inclusion and exclusion of the virus was illustrated with a PRISMA diagram. We collected the selected studies in an evaluation table, evaluated them according to the level of evidence, and performed a thematic analysis. Results: Of the 436 hits, we included eight in the final analysis. The results show that preventive measures for preventing healthcare-associated infections in incubated preterm infants are a complex process in which four areas play a key role: organizational barriers to implementing measures, training and education of healthcare staff, disinfection of incubators, and the role of parents and management in preventing healthcare-associated infections. Discussion and conclusion: Healthcare-associated infections cause complications, prolong hospitalization, and increase the risk of mortality, and research confirms that despite progress, they still represent a major challenge. Therefore, consistent implementation of preventive measures is crucial for the safe care of premature infants in incubators
