1. Software self-hosting : a systematic review of quantitative research☆Luka Hrgarek, Lili Nemec Zlatolas, 2025, izvirni znanstveni članek Opis: In an era marked by heightened concerns surrounding personal privacy and data security, software self-hosting has gained significance as a means for individuals and organizations to reclaim control over their digital assets. This systematic review aims to identify relevant research gaps in the quantitative analysis of self-hosting, primarily focusing on studies employing Structural Equation Modeling (SEM) and regression techniques. Employing a refined version of the Systematic Mapping Process, we analyzed 49 quantitative research papers whose concepts were grouped into 12 substantive groups. The findings reveal a predominant concentration on constructs related to the Technology Acceptance Model (TAM), with limited exploration of self-hosting specifically, overshadowed by an emphasis on cloud computing, the Internet of Things (IoT), and privacy aspects. Our review provides a comprehensive overview of the existing literature and highlights the need for more focused research on self-hosting itself. This systematic review serves as a foundational resource for researchers and practitioners aimed at advancing the discourse on self-hosting.

2. A product quality impacts of a mobile software product line : an empirical studyLuka Pavlič, Tina Beranič, Marjan Heričko, 2021, izvirni znanstveni članek Opis: Background: The software product lines (SPL) enable development teams to fully address a systematic reuse of shared assets to deliver a family of similar software products. Mobile applications are an obvious candidate for employing an SPL approach. This paper presents our research outcomes, based on empirical data from an industry-level development project. Two development teams were confronted with the same functionalities set to be delivered through a family of native mobile applications for Android and iOS.
Methods: Empirical data was gathered before, during and after a year of full-time development. The data demonstrate the impact of a SPL approach by comparing the SPL and non-SPL multiple edition development. One family of products (Android apps) was developed using an SPL approach, while another (iOS apps), functionally the same, was developed without employing an SPL approach. The project generated a volume of raw and aggregated empirical data to support our research questions.
Results: The paper reports a positive impact of an SPL approach on product quality (internal and external) and feature output per week. As data shows, it also increases the delivery of functionalities (240% in 6 more editions), while investing the same amount of effort needed for a single-edition development. As a result of system-supported separation of development and production code, developers had a high confidence in further development. On the other hand, the second team delivered less new functionalities, only two new application editions, and lower software quality than the team that manages multi-edition development by employing an SPL approach.

5. Optimizacija postopka kalibracije jeklenih kotnikov : magistrsko deloLuka Štelcer, 2025, magistrsko delo Opis: V magistrski nalogi smo se osredotočili na optimizacijo postopka kalibracije jeklenih kotnikov s pomočjo koordinatne merilne naprave, s čimer smo skrajšali čas kalibracije ter razbremenili kader laboratorija. Za izdelavo univerzalnega programa smo uporabili programski paket PC-DMIS. Izračunali smo merilno negotovost novega postopka, ki je bila primerljiva klasičnemu procesu umerjanja. Z uporabo univerzalnega programa lahko izvajamo kalibracije za različno velike kotnike ter tipe le–teh, prav tako pa lahko podajamo pravokotnost zunanjega kraka na notranjo referenčno ploskev ter pravokotnost notranjega kraka na zunanjo referenčno ploskev.

7. Medijska pismenost z metodo časopisnega gledališča : magistrsko deloLuka Kristić, 2025, magistrsko delo Opis: V magistrskem delu obravnavamo časopisno gledališče kot inovativno metodo za poučevanje medijske pismenosti. S kvalitativno analizo intervjujev s strokovnjaki tega področja smo ugotovili, da se s časopisnim gledališčem lahko poučuje medijsko pismenost. Metoda spodbuja kritično mišljenje, analiziranje, preizpraševanje in ustvarjanje (medijskih) vsebin. Ključne značilnosti so opolnomočenje, kreativni pedagoški pristop, kulturni kontekst in humor. Rezultati tudi kažejo, da časopisno gledališče spodbuja kritično medijsko pismenost in ponuja kreativno orodje ter družbeno ozaveščanje. Priporočena so nadaljnja raziskovanja na večjem vzorcu, kakor tudi raziskovanja o dolgoročnem vplivu metode na učence in občinstvo.

8. Biaxial structures of localized deformations and line-like distortions in effectively 2D nematic filmsLuka Mesarec, Samo Kralj, Aleš Iglič, 2024, izvirni znanstveni članek Opis: We numerically studied localized elastic distortions in curved, effectively two-dimensional nematic shells. We used a mesoscopic Landau-de Gennes-type approach, in which the orientational order is theoretically considered by introducing the appropriate tensor nematic order parameter, while the three-dimensional shell shape is described by the curvature tensor. We limited our theoretical consideration to axially symmetric shapes of nematic shells. It was shown that in the surface regions of stomatocyte-class nematic shell shapes with large enough magnitudes of extrinsic (deviatoric) curvature, the direction of the in-plane orientational ordering can be mutually perpendicular above and below the narrow neck region. We demonstrate that such line-like nematic distortion configurations may run along the parallels (i.e., along the circular lines of constant latitude) located in the narrow neck regions of stomatocyte-like nematic shells. It was shown that nematic distortions are enabled by the order reconstruction mechanism. We propose that the regions of nematic shells that are strongly elastically deformed, i.e., topological defects and line-like distortions, may attract appropriately surface-decorated nanoparticles (NPs), which could potentially be useful for the controlled assembly of NPs.

9. Models of privacy and disclosure on social networking sites: a systematic literature reviewLili Nemec Zlatolas, Luka Hrgarek, Tatjana Welzer-Družovec, Marko Hölbl, 2022, izvirni znanstveni članek Opis: Social networking sites (SNSs) are used widely, raising new issues in terms of privacy and
disclosure. Although users are often concerned about their privacy, they often publish information
on social networking sites willingly. Due to the growing number of users of social networking sites,
substantial research has been conducted in recent years. In this paper, we conducted a systematic
review of papers that included structural equations models (SEM), or other statistical models with
privacy and disclosure constructs. A total of 98 such papers were found and included in the analysis.
In this paper, we evaluated the presentation of results of the models containing privacy and disclosure
constructs. We carried out an analysis of which background theories are used in such studies and
have also found that the studies have not been carried out worldwide. Extending the research to
other countries could help with better user awareness of the privacy and self-disclosure of users
on SNSs.

10. Opazovalnik temperature spoja močnostnega modula : magistrsko deloRadoslav Pantić, 2025, magistrsko delo Opis: Namen magistrskega dela je zagotoviti bolj natančno oceno temperature spoja MOSFET-tranzistorja v primerjavi z obstoječim pristopom, kar bo omogočilo izboljšanje zmogljivosti motorskega krmilnika. Ta temperatura predstavlja ključno, vendar nedostopno stanje, ki ga ni mogoče neposredno izmeriti. Zato smo razvili predikcijski algoritem, imenovan opazovalnik, ki na podlagi meritev vhodov oziroma faznega toka in temperature na dostopni točki sistema ocenjuje temperaturo spoja MOSFET-tranzistorja. V ta namen smo načrtali termalni model krmilnika, predstavljen kot ekvivalentno električno vezje, in ga nato validirali z uporabo termalnih simulacij v časovni domeni in meritvami.
Ključne besede: predikcijski algoritem, MOSFET, termalni model, motorni krmilnik, prostor stanj
