2. Monte Carlo study of a single SST-1M prototype for the Cherenkov Telescope ArrayJ. Juryšek, Christopher Eckner, Gašper Kukec Mezek, Samo Stanič, Serguei Vorobiov, Lili Yang, Gabrijela Zaharijas, Danilo Zavrtanik, Marko Zavrtanik, Lukas Zehrer, 2019, objavljeni znanstveni prispevek na konferenci Opis: The SST-1M telescope was developed as a prototype of a Small-Size-Telescope for the Cherenkov Telescope Array observatory and it has been extensively tested in Krakow since 2017. In this contribution we present validation of the Monte Carlo model of the prototype and expected
performance in Krakow conditions. We focus on gamma/hadron separation and mono reconstruction of energy and gamma photon arrival direction using Machine learning methods.

3. BLUE YE WINDElizabeta Sitņikova, Inga Šlangena, Eliza Cipruse, druga izvedena dela Opis: Inspired by Rosi Braidotti's posthumanist theory, this collective artwork, born from a blend of human and non-human creative forces, ventures beyond the human subject. It reveals unexpected artistic materializations where machines, like invasive species, permeate the natural environment. As the workshop particpants resonated with the disenfranchised maritime landscapes, they now take the audience along to question the boundaries between their nature and the blue expanse. Through sensory engagement that deprioritizes the visual, the audience is invited to reframe their perception and interaction with the sea, and their consistency of and with water.

4. Non-oxidative calcination enhances the methane dry reforming performance of ▫$Ni/CeO_{2−x}$▫ catalysts under thermal and photo-thermal conditionsKristijan Lorber, Vasyl Shvalya, Janez Zavašnik, Damjan Vengust, Iztok Arčon, Matej Huš, Andraž Pavlišič, Janvit Teržan, Uroš Cvelbar, Blaž Likozar, Petar Djinović, 2024, izvirni znanstveni članek Opis: We analyzed the effect of the calcination atmosphere and visible-light contribution to an accelerated
reaction rate and improved H2 selectivity over 2 wt% Ni/CeO2−x nanorod catalysts. Spectroscopic and
structural characterization was performed by operando DRIFTS, in situ Raman, UV-vis and XAS
techniques, which were complemented by DFT calculations. Calcination in an argon or H2 atmosphere
yields 15% more active catalysts in the thermally driven reaction, which are also more susceptible to
light-induced rate acceleration compared to the catalyst calcined in air. The most active 2Ni/CeO2
catalyst calcined in hydrogen converts methane with a rate of 7.5 mmol (gcat min)−1 and produces a H2/
CO ratio of 0.6 at 460 °C when stimulated by a combination of visible light and thermal energy. In the
absence of visible light illumination and at an identical catalyst temperature, the achieved methane rate
was 4.2 mmol (gcat min)−1 and the H2/CO ratio was 0.49. The non-oxidative calcination improves nickel
dispersion and the formation of subnanometer sized Ni clusters, together with a higher abundance of
surface and bulk oxygen vacancies in ceria nanorods. The Ni–Ov–Ce3+components constitute the
catalytically active sites under visible light illumination, which enable the DRM reaction to proceed with
an Ea value of 20 kJ mol−1. Visible light also induces the following changes in the 2Ni/CeO2−x catalyst
during the DRM reaction: (1) decomposition and desorption of carbonates from the nickel–ceria
interface sites, (2) reduced population of nickel surface with carbonyl species and (3) promoted
adsorption and dissociation of methane.

5. Defining worst-performing buildings in Slovenia based on EPCsMarjana Šijanec-Zavrl, Henrik Gjerkeš, 2023, objavljeni znanstveni prispevek na konferenci Opis: The 2021 EC proposal for EPBD recast planned inter alia the harmonization of energy performance certificates (EPCs) across EU and definition of minimum energy performance (MEP) standards to support the renovation of worst-performing buildings. Rescaling of EPCs to a common EU ranking and consequently setting MEP standards is a task for the near future, but current planning of building renovation to meet decarbonization by 2050 may only relay on data in Slovenian EPCs from 2013-2022 data base. The paper presents the analysis of energy related indicators in existing Slovenian EPCs in order to demonstrate that existing EPCs issued in last decade can be used to define 15% of worst-performing buildings prioritized for deep and NZEB renovation, if combined with other indicators, like heat demand.

6. Implementation of the EPBD in Slovenia – Status in 2020Marjana Šijanec Zavrl, Miha Tomšič, Henrik Gjerkeš, Erik Potočar, 2021, končno poročilo o rezultatih raziskav Opis: The Concerted Action EPBD (CA EPBD) addresses the Energy Performance of Buildings Directive (EPBD). It aims to contribute to the reduction of energy use in European buildings, through the exchange of knowledge and best practices in the field of energy efficiency and energy savings between all 28 EU Member States plus Norway.
The CA EPBD is a joint initiative between the EU Member States and the European Commission. It involves representatives of national ministries or their affiliated institutions who are in charge of preparing the technical, legal and administrative framework for the Energy Performance of Buildings Directive in each EU Member State, plus Norway. The objective is to enhance the sharing of information and experiences from national adoption and implementation of this important European legislation.
The transposition of the EPBD in Slovenia is the overall responsibility of the Ministry of Infrastructure and was primarily transposed by the Energy Act (EZ-1), covering the topics of NZEB, energy performance certification, inspection of heating and AC systems and energy efficiency information programmes. The Act on Energy Efficiency (ZURE) integrates the EZ-1 articles related to the EPBD.
The revision of the building codes (PURES) is still in progress and planned for publication in late 2021. It will contain detailed technical requirements for NZEB based on the technical definition given in the national NZEB action plan, and the revision of the calculation methodology according to a new set of CEN EPBD standards.
Important recent steps in EPBD implementation are the application of the central national electronic register of EPCs and associated software, the independent control system for EPCs, first steps in the cross-linking of e-registries for EPCs, inspections and public buildings, as well as wide information activities implemented by the Eco Fund concerning financial instruments available for the energy renovation of buildings.

7. Unlearning tabooPeter Purg, 2023, umetniško delo Opis: Along the TTT 2023 programme, the performer selected and remixed fragments of both
artworks (installations and performances) as well as discursive contributions in a
way that corresponds to the principles of Bertolt Brecht’s “Lehrstücke,” the so-called
learning or teaching pieces that deconstruct and expose the mechanisms of (power)
relationships inherent to the (media/art) system in question.
Provoking both rational and irrational perspectives, possibilities of (un)learning through
acting, playing roles, adopting postures etc. was explored, dissolving (or at least
questioning) the divide between authors and audiences, both invited (in Brechtian terms)
to acquire attitudes rather than to consume an entertainment.
Ključne besede: unlearning, deconstruction, roleplay, participative performance, transgressive formats

9. Comparison of Effectiveness between Traditional and Digital Marketing in a Selected CompanyVeronika Stoilkovska, 2022, diplomsko delo Opis: The thesis contains the differences between traditional and digital marketing, a
comparison between the advantages and disadvantages for both marketing methods,
types of channels they have, methods of calculating the effectiveness of both methods
and research to show how theory can be put into application in the real world, and
what kind of results come out.
The research is based on data from a selected company, Bolton Adriatic d.o.o., where
there are consumer brands from three types of industries: house cleaning brand, food
brand, and personal care brand. These brands are introduced by traditional ways of
marketing, digital ways of marketing, and both marketing ways. The goal of the
research is to show the performance of different channels in the year of 2020.
The approach to the research is secondary based. Quantitative data was gathered from
archives and analysed further into descriptive representation.
Ključne besede: Traditional marketing, digital marketing, effectiveness, data, performance, comparison, metrics, key performance indicators, advantages and disadvantages
