Building integrated microgrids (BIMs) present a promising step towards a more efficient, decentralized and sustainable power system. Many buildings already have various renewable energy sources (RES) integrated, but the next step is adding energy storage (ES) systems, or proactive loads such as electric vehicles (EVs) to an already established system. However, ensuring the resilience of the system to accept these new elements presents a challenge in terms of stability, efficiency, and operational capability. This paper focuses on size optimized BIM simulated on Typhoon Hardware-in-the-Loop (HIL) platform using real measured load and PV production data. A rule-based energy management system (EMS) is proposed and its effective-ness is analyzed through testing resilience of the system under consideration. Performance analysis is conducted by adding an EV and assessing system response in several scenarios of load and EV use profiles. Through Typhoon HIL simulations the power profiles of system elements are analyzed, leading to conclusions on BIM performance.

The consumers with building integrated photovoltaic (PV) systems have become prosumers, and their profit depends on network regulations, especially in the treatment of surplus electricity. Net-metering and feed-in tariff are the most common remuneration mechanisms for prosumers. Increasing the number of prosumers can cause various technical problems in the grid, therefore the distribution system operator sometimes imposes legal/regulatory and technical restrictions that are reflected in zero energy export. Integration of the energy storage systems can help with problems arising from these restrictions, but will make the initial investment significantly more expensive. This may negatively affect the profitability of investment. The main aim of this paper is analysis of different regulatory policies and their impact on building integrated PV system profitability. Two profitability metric factors were calculated for the purpose of better policy comparison. For the presented analysis, real data sets of a load demand and PV energy production were used. As an example, the integrated PV system installed at the Faculty of EE University of Sarajevo is analyzed.

A fast-paced policy context is characteristic of energy and climate research, which strives to develop solutions to wicked problems such as climate change. Funding agencies in the European Union recognize the importance of linking research and policy in climate and energy research. This calls for an increased understanding of how stakeholder engagement can effectively be used to co-design research questions that include stakeholders'concerns. This paper reviews the current literature on stakeholder engagement, from which we create a set of criteria. These are used to critically assess recent and relevant papers on stakeholder engagement in climate and energy projects. We obtained the papers from a scoping review of stakeholder engagement through workshops in EU climate and energy research. With insights from the literature and current EU climate and energy projects, we developed a workshop programme for stakeholder engagement. This programme was applied to the European Climate and Energy Modelling Forum project, aiming to co-design the most pressing and urgent research questions according to European stakeholders. The outcomes include 82 co-designed and ranked research questions for nine specific climate and energy research themes. Findings from the scoping review indicate that papers rarely define the term'stakeholder'. Additionally, the concepts of co-creation, co-design, and co-production are used interchangeably and often without definition. We propose that workshop planners use stakeholder identification and selection methods from the broader stakeholder engagement literature.

Flavor deconstruction refers to non-universal gauge extensions where the original gauge symmetry is deconstructed into separate copies, one for each family. A hierarchical chain of symmetry breaking provides an attractive low-scale solution to the flavor puzzle, consistent with flavor-changing neutral currents and finite naturalness. Although successful in explaining the origin of flavor hierarchies in the quark and charged lepton sectors, existing models have struggled with the large and seemingly anarchic mixing observed in neutrino oscillations. This letter identifies conditions under which neutrino anarchy may arise from flavor deconstruction in generic models with right-handed neutrinos. When deconstruction is applied to carefully chosen subgroups of the extended gauge symmetry, hierarchies in the seesaw formula cancel out.

Background: Most human movements are supported by its functional capabilities of the anaerobic type, which is dominated by submaximal and maximal sports activities performed in a short time. Functional capabilities of the anaerobic type of man participate in most of his movement activities. Conditioned on adequate and extremely good interaction and functioning of the cardiovascular and respiratory systems, morphological status, metabolic processes, muscle structure, nutritional status, physical activity, etc. Purpose: The research was conducted in the conditions of the so-called field testing with the primary goal of assessing the acute state of anaerobic abilities of physical and sports students, by calculating the fatigue index (FI). Methods: The sample included 80 students of Physical and Sports Education, different geographical regions, average weight 77.88±8.49kg, age 20-23 years. The Running Anaerobic Sprint Test (RAST) was used to assess FI, and the basic statistical parameters were calculated. Results: The average value of the student's leg power is 573.89 watts (378.42 watts vs. 817.99watts), and the recorded average (FI) of 8.35 watts/sec (3.97watts/sec. vs. 16.93watts/sec.). Conclusions: The obtained results confirmed the average values of anaerobic capacity which are suitable for the examined population of subjects, while the maximal the value of FI suggests a weaker state of the anaerobic capacity of the individuals (less tolerance to lactates).

We prove that $J(R_e)=R_e\cap J(R),$ where $S$ is a cancellative partial groupoid with idempotent $e,$ $R=\bigoplus_{s\in S}R_s$ an Artinian $S$-graded ring inducing $S,$ $J(R)$ the Jacobson radical of $R$ and $J(R_e)$ the Jacobson radical of $R_e.$ We also prove that $J(R)$ is nil if $J(R_e)$ is nil under certain assumptions.

Independent of the respective NFC (near field communication) application the specific NFC device has to be tested for standard compliance. In the present work we propose a hybrid surrogate-model based synthesis strategy which enables the incorporation of standard compliance tests in the synthesis process. While the surrogate model is used in early optimization phases applying a stochastic optimization strategy, the highfidelity model is applied in the final deterministic optimization part. The high fidelity model is based on a thin wire partial element equivalent circuit method.

Abstract Digital technology has become inseparable from all core and supportive processes because of the intensive use of different digital tools. The paper aimed to determine teachers’ views on the impact of digital technology on business processes in higher education institutions - whether they recognize the impact and how they evaluate it. The survey was conducted among the teachers of the public University in Bosnia and Herzegovina. The results show that digital technology has a positive and mostly strong or medium impact on business processes in higher education institutions. The work on international research and educational projects and the teaching process are the most influenced by digital technology. It has a stronger impact on the core processes than on supportive activities. Teachers recognize the influence of digital transformation on all processes at universities, both core and supporting. The influence is stronger with core processes.

Abstract This literature review focuses on concepts related to the role of information technology (IT) capabilities and managerial support in the context of advancing digital transformation and improving internal audit in the institutional environment. Through the synthesis of relevant academic sources, it is investigated how IT capacities and strategic management support influence the organizational ability to adapt to digital innovations. Special emphasis is placed on the complex dynamics that shape the interactions between these factors and their impact on institutional responsibility and performance. The results of the literature review illustrate the key mechanisms that support the digital transformation process, including the integration of technological systems, the development of digital competencies, and the role of management in providing resources and support. Further, a deeper understanding of the complexity of these interactions serves as a basis for further research in the field of digital transformation management and internal audit in an institutional context.

Physical literacy (PL) is the foundation for lifelong participation in physical activity. Most previous research concentrated on PL examinations in younger groups, while such research is scarce in the adult population. This study aimed to determine the PL levels of the Croatian adult population. Also, the aim was to investigate whether individuals with longer participation in organized physical activity have higher PL levels and do males and females differ in PL levels. The sample comprised 561 individuals (321 females, 240 males) aged 27.65±12.13 years. PL levels were assessed by the Croatian version of the Perceived Physical Activity Questionnaire (PPLQ-Cro). Demographic characteristics included age, gender, and years of involvement in organized physical activity. Gender differences were calculated using the Mann-Whitney U test and effect sizes. Spearman correlation coefficients were used to determine associations between study variables. Males had significantly higher PL levels compared to females (83.10±16.17 for males and 74.27±20.07 for females, Z=-6.88, p=0.001). Years of organized physical activity were associated with PL levels (R=0.48, p=0.001) in the total sample as well in males (R=0.55, p<0.001) and females (R=0.24, p<0.01) separately. The finding that years of organized physical activity are associated with total PL supports the theory that PL is the cornerstone for participating in lifetime physical activity. The results of this study emphasize the importance of introducing the concept of PL in numerous institutions and organizations connected with organized physical activity.

Factors associated with doping in sports are frequently studied, but sport specific, gender-stratified investigations are rare. This study aimed to evaluate sociodemographic and sport factors associated with doping tendency (DT) in professional handball players. The participants were handball professionals from Croatia and Bosnia and Herzegovina (n=173; 22.12±3.11 years of age, 64 females and 109 males) who were tested on sociodemographic variables (gender, age, education), sport factors (experience in sport, achievement at the junior and senior level), and doping factors (personal opinion on the problem of doping, doping knowledge, and personal DT). Logistic regressions with sociodemographic- and sport-factors as predictors were calculated for binarized outcome (positive DT vs. negative DT). A greater likelihood of having a positive DT was found for males than for females (OR=1.60, 95% CI: 1.16-2.12) and for those who achieved success at the junior level (OR=1.21, 95% CI: 1.02- 1.95). Among females, positive DT increased with experience in handball (OR=1.31, 95% CI: 1.11-1.55). Male players who achieved better competitive/sport results at a younger age were more prone to doping (OR=1.50, 95% CI: 1.21-1.83). While a greater tendency toward doping in males might be expected due to sociocultural factors, the gender-specific associations indicated specific factors that must be noted in the development of anti-doping strategies in this sport.

One strategy for utilizing ammonia as an energy vector is to replace conventional hydrocarbons with hydrogen-enriched ammonia in existing or retrofitted combustors. However, the strong differential diffusion effect of hydrogen can significantly alter the combustion properties and cause challenges in combustor operability. Therefore, this numerical study performs a systematic investigation on the effect of differential diffusion on fundamental combustion properties of ammonia/hydrogen fuel blends. The investigated combustion properties span from the initiation of combustion, i
