1. Analysis of synchronous generators’ local mode eigenvalues in modern power systemsJožef Ritonja, Boštjan Polajžer, 2022, izvirni znanstveni članek Opis: New energy sources, storage facilities, power electronics devices, advanced and complex
control concepts, economic operating doctrines, and cost-optimized construction and production of
machines and equipment in power systems adversely affect small-signal stability associated with local
oscillations. The objective of the article is to analyze local oscillations and the causes that affect them in
order to reduce their negative impact. There are no recognized analyses of the oscillations of modern
operating synchronous generators exposed to new conditions in power systems. The basic idea is to
perform a numerical analysis of local oscillations of a large number of synchronous generators in
the power system. The paper represents the local mode data obtained from a systematic analysis of
synchronous generators in the Slovenian power system. Analyzed were 74 synchronous generators
of the Slovenian power system, plus many additional synchronous generators for which data were
accessible in references. The mathematical models convenient for the study of local oscillations
are described first in the paper. Next, the influences of transmission lines, size of the synchronous
generators, operating conditions, and control systems were investigated. The paper’s merit is the
applicable rules that have been defined to help power plant operators avoid stability-problematic
situations. Consequently, boundaries were estimated of the eigenvalues of local modes. Finally,
experiments were performed with a laboratory-size synchronous generator to assess the regularity of
the numerically obtained conclusions. The obtained results enable the prediction of local oscillations’
frequencies and dampings and will be useful in PSS planning.

2. Integrating participatory approaches and fuzzy analytic hierarchy process (FAHP) for barrier analysis and ranking in urban mobility planningUroš Kramar, Marjan Sternad, 2025, izvirni znanstveni članek Opis: This study examines the barriers to implementing sustainable mobility strategies in small municipalities by integrating participatory and multi-criteria decision-making methods. A triangulated approach combines the nominal group technique (NGT), focus groups (FGs), and the fuzzy analytic hierarchy process (FAHP) to systematically identify, refine, and rank key barriers. The NGT enables stakeholders to list and prioritize barriers individually, ensuring balanced participation. FG discussions then refine and contextualize these barriers, addressing qualitative depth. Finally, the FAHP quantitatively ranks the barriers while accounting for uncertainty in stakeholder judgments. The results highlight systemic constraints, such as financial limitations and regulatory inefficiencies, alongside local challenges like inadequate infrastructure and public resistance. Integrating the NGT, FGs, and the FAHP enhances the analytical rigor by merging structured decision-making with participatory engagement. This methodological innovation strengthens the reliability of barrier assessment and offers a replicable framework for urban mobility planning. The findings underscore the need for locally tailored strategies that balance stakeholder inclusion with structured prioritization, contributing to improved governance in sustainable transport planning.

3. Lipid deposition and metabolism in local and modern pig breeds : a reviewKlavdija Poklukar Žnidaršič, Marjeta Čandek-Potokar, Nina Batorek Lukač, Urška Tomažin, Martin Škrlep, 2020, pregledni znanstveni članek Opis: Modern pig breeds, which have been genetically improved to achieve fast growth and a lean meat deposition, differ from local pig breeds with respect to fat deposition, fat specific metabolic characteristics and various other properties. The present review aimed to elucidate the mechanisms underlying the differences between fatty local and modern lean pig breeds in adipose tissue deposition and lipid metabolism, taking into consideration morphological, cellular, biochemical, transcriptomic and proteomic perspectives. Compared to modern breeds, local pig breeds accumulate larger amounts of fat, which generally contains more monounsaturated and saturated fatty acids; they exhibit a higher adipocyte size and higher activity of lipogenic enzymes. Studies using transcriptomic and proteomic approaches highlighted several processes like immune response, fatty-acid turn-over, oxidoreductase activity, mitochondrial function, etc. which differ between local and modern pig breeds.

4. Assessment of concept between rural development challenges and local food systems : A combination between Multi-criteria decision analysis and econometric modelling approachJernej Prišenk, Jernej Turk, 2022, izvirni znanstveni članek Opis: This study investigates the influence of social, economic, and environmental impacts on the promotion and marketing systems of local food products from mountain areas in Slovenia. These impacts were assessed using an econometric modelling approach. Two econometric models were developed (one for production and one for marketing). The case studies of local food products were selected from Slovenian mountain regions, most of which were from less-favored areas (LFAs). A majority of the selected food commodities were of high quality, with or without protected designations. Data collection was carried out via interviews. Due to production limitation on mountain areas in Slovenia and other constraints in LFAs, the socio-economic and environmental impacts on success of production and marketing systems need to be clarified. These relations present a potential impact on the wider socio-economic development in the region. The empirical results, obtained using an econometric modelling approach, clearly show the importance of encouraging the socio-economic and environmental impacts in ensuring the marketing and production potentials of local food products. The result express good relationships, and cooperation between the actors in the food supply chains contributing to a successful marketing system and production system of local food products (small, average, large) is dependent on the available local labour in mountain rural areas.

8. Development of a local event 'Summer in Samobor'Nika Martina Mišić, 2023, diplomsko delo Opis: Events are one of the main factors of tourism development of a destination. Also, local events are one of the biggest factors that influence tourism in every town, city or community, and they are of great importance for a tourist destination. Summer in Samobor is a particularly successful new event that is in the process of development. In the theoretical part of the graduate thesis, the following topics are explained: the significance of the event, the type and size of the event, the planning and realisation of the event and the sustainability of the event. In the first part of our research, we presented
the theoretical knowledge on the subject. Then we presented the event Summer in
Samobor taking into account the following factors: aims and visions of the event, programme of the event, place and time of the event, registrations and permits, financial management, sponsors, media and promotion, food and beverages, and finally the sustainability of the event. As part of our research, we conducted interviews with the representative of the external agency Wanderlust Events and the representative of the Samobor Tourist Board. Using the interviews mentioned, we found out how the event developed, what factors influenced the success of the event and how sustainable the event is. The results of this research show that this event is developing every year and that the quality of the event is constantly being raised. Also, as some of the main success factors of the event Summer in Samobor, the following were emphasized: improvement of socio-cultural awareness, strong promotion of sustainable events, rich and high-quality content,uniqueness, cooperation and support of partners, good organization and creative ideas.

9. Research on vehicle re-identification algorithm based on fusion attention methodPeng Chen, Shuang Liu, Simon Kolmanič, 2023, izvirni znanstveni članek Opis: The specific task of vehicle re-identification is how to quickly and correctly match the same vehicle in different scenarios. In order to solve the problem of inter-class similarity and environmental interference in vehicle images in complex scenes, one fusion attention method is put forward based on the idea of obtaining the distinguishing features of details-the mechanism for the vehicle re-identification method. First, the vehicle image is preprocessed to restore the image's attributes better. Then, the processed image is sent to ResNet50 to extract the features of the second and third layers, respectively. Then, the feature fusion is carried out through the two-layer attention mechanism for a network model. This model can better focus on local detail features, and global features are constructed and named SDLAU-Reid. In the training process, a data augmentation strategy of random erasure is adopted to improve the robustness. The experimental results show that the mAP and rank-k indicators of the model on VeRi-776 and the VehicleID are better than the results of the existing vehicle re-identification algorithms, which verifies the algorithm's effectiveness.

10. Cultural events as tools of developing sustainable tourism in rural areas : the case of Sevnica in SloveniaJasna Potočnik Topler, 2021, izvirni znanstveni članek Opis: The purpose of this article is to identify cultural tourism as one of the best practices that can help in the implementation of the Strategy for Sustainable Growth of Slovenian Tourism (2017 - 2021) and to examine the role of cultural events as tools for the development of sustainable tourism. The latter is one of the main trends in the tourism sector, at least in the European context and also in Slovenia as a member country of the European Union. The challenge of developing sustainable tourism destinations is considerable in rural areas, where local communities must be closely observed and by all means included in the decision-making process on future tourism development. This is of the utmost importance as tourism is much more than an economic activity. Therefore, key decision-makers need to be aware that tourism activities affect all local people and many areas of their life and that the role of tourism in rural areas is to improve the quality of life of the local population. Since at least some form of culture can be found in every village, small (rural) tourist destinations often find important opportunities for sustainable tourism development in organizing cultural events, which lead to greater community visibility, cultural branding of the destination, which is significant and also several business opportunities. On the case of Sevnica, this article aims to demonstrate that there is great potential for further development of cultural tourism and its subtypes in Slovenia by further developing cultural tourism and various tourism products based on rich cultural heritage.
