In order to preserve indigenous and locally adapted breeds through development programs for sustainable egg and meat production, it is necessary to have more data on the potential of these breeds in different production conditions. Accordingly, the objective of the study was to determine and compare the reproductive potential, production performance and egg quality of two indigenous poultry breeds: the Banat Naked Neck (BNN) and the Svrljig Hen (SH), in improved growing conditions (nutrition,...

This study employs a novel physics-informed neural networks (PINN) approach, standard explicit finite difference method (EFDM) and Chen-Charpentier et al.’s finite difference method (CCFDM) to tackle the one-dimensional Sine-Gordon equation (SGE). Two test problems with known analytical solutions are investigated to demonstrate the effectiveness of these techniques. While the three employed approaches demonstrate strong agreement, our analysis reveals that the EFDM results are in the best agr...

One of the barriers to the rapid transition of societies toward a more sustainable future is a scarcity of field experts. Members of scientific and professional communities believe that this obstacle could be overcome by supplementing the decisions of non-experts with artificial intelligence. To examine this opportunity, this study examines the viability of GPT-3.5 as an expert adviser in the energy management of kindergartens. Thus, field experts investigated the deductive and inductive reas...

In the era of digitization, small and medium-sized enterprises (SMEs) face significant challenges due to the obsolescence of production equipment that cannot meet modern business requirements. Enterprises engaged in mechanical processing of metal, wood and other materials are characterized by a significant share of older generation equipment, which is considered to be unusable from the aspect of modern trends in the field of production. The aim of this paper is to consider the possibility of ...

To encourage proper waste management for electrical and electronic devices (e-waste), it is necessary to invest heavily in the development of recycling technologies. One way to improve the process is to automate separating the shredded parts of e-waste using a robot. This paper’s literature review, utilizing the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) framework, showcases potential robotic technologies for e-waste separation. However, the intricate design o...

Computerized compliance of Personal Protective Equipment (PPE) is an emerging topic in academic literature that aims to enhance workplace safety through the automation of compliance and prevention of PPE misuse (which currently relies on manual employee supervision and reporting). Although trends in the scientific literature indicate a high potential for solving the compliance problem by employing computer vision (CV) techniques, the practice has revealed a series of barriers that limit their...

The CNC dry turning of Inconel 625 alloy was investigated in this study. Turning was performed using different feeds, corner radii, and insert types. The dimensions and the arithmetic mean surface roughness were measured before and after turning. The influence of the input parameters and the process modelling were evaluated using a full factorial design of experiments. Prediction models were developed, and process optimization was carried out to simultaneously maximize dimensional accuracy an...

There is a great need for the unification and integration of several technologies and services into one product suitable for helping e-government and other public-sector services as well as private company administration to support advanced search services. For corporate operations in the Serbian speaking region and surrounding areas (Serbian and similar languages), the authors suggest a framework that will be an extension of the previously proposed SEFRA framework. Along with updating ...

This project proposes the integration of version control and revision history functionalities into the online document management system. Users will be able to track changes made to documents, view previous versions, and revert to earlier iterations. The system will allow users to leave comments or annotations on specific versions, facilitating collaboration and feedback processes. AI will advance the mentioned functions while the usage of blockchain will reduce the risk of unexpected...
