Keywords: Inclusive Digital Education; Universal Design; Assistive Technologies; Web Content Accessibility Guidelines; Universal Design for Learning
The prevalence of technology in all aspects of society, education, and work presents new opportunities to overcome challenges associated with vulnerable participants' inclusion. The proliferation of digital technologies in education, encompassing diverse technology-enhanced learning implementations like blended learning, online courses, simulations, virtual classrooms, and mobile learning, necessitates a paradigm shift based on the effective application of inclusive design principles and frameworks towards ensuring the learning environments, teaching materials, and educational services that are universally usable by all students, to the maximum extent possible. Researchers and experts in education and instructional design discuss and experiment with many proactive methodologies and instructional design approaches that prioritize the needs of a heterogeneous user base in digital learning environment development. The current paper presents some results and findings of a study that investigates globally recognized methodologies, principles, and frameworks for the design and development of inclusive digital learning environments carried out within the Erasmus+ project „Inclusive Digital Learning (Dig-2-Inc, 2022-1-FI01-KA220-HED-000090147).

Keywords: Tetrahedral amorphous Carbon, ta-C; Pulsed arc deposition; Doped ta-C
Hydrogen-free tetrahedral bonded amorphous Carbon films (ta-C), W doped, and B doped ta-C were deposited by a special pulsed arc technique based on a non-equilibrium process. Their structure is mainly determined by the energy of the impinging the substrate Carbon ions and the following relaxation effect linked with the temperature of the coating during deposition. In addition, the implantation depth is heavily influenced by the angle of incidence of the ions. Furthermore, the deposition rate was checked for various pulse architectures, and for Boron (B) and Tungsten (W) doped C targets. There is a clear effect that a deposition rate above a certain threshold value negatively influences the hardness.

The physical properties of deposited Carbon-based films are strongly dependent on the ratio of sp2 (graphite-like) to sp3 (diamond-like) bonds. In the “Subplantation model” of Lifshitz et al. and of Robertson, incident ions of sufficient energy penetrate the surface of the growing film, enter interstitial subsurface and increase the local density. The ions with lower energy will not be able to penetrate the surface and will form sp2 bonds. Thus, the structure of the deposited films is mainly determined by the energy of the impinging the substrate Carbon ions and the following relaxation effect linked with the temperature during deposition. For this study films were deposited using pulsed arc technic. There are clear facts how deposition rate influences the nano-hardness and roughness of the coatings. It was also found that dopants can significantly increase the deposition rates.

Keywords: Renewable energy; SCADA; power systems; security.
SCADA systems are one of the industrial control systems that are used to automate and control multiple processes and operations. Nowadays, SCADA systems are applied in various large-scale fields such as energy, as well as oil, gas and water transportation. The components of the system are geographically distributed over a very large distance and must be possible to be centrally monitored and managed.

Keywords: Artificial intelligence; robots; successful people; productivity; positive psychology; resources; theories; development; success.
The aim of the study is to analyze the way in which artificial intelligence and robots support the development of people defined as successful from the perspective of the psychological theories of Abraham Maslow, Martin Seligman and Mihaly Csikszentmihalyi. Additionally, the methods that contribute to achieving success in personal and career development are discussed, as well as the possibility of including artificial intelligence and robots in favor of success. The way in which robots benefit humans and complement their resources and success is also presented.

Keywords: EMF; extremely low frequency magnetic fields (ELF-MF); energy system
In the modern power system, transformers play a key role in converting voltages for efficient transmission and distribution of electricity. The study of electromagnetic fields around these transformers is essential to ensure their safe and reliable operation as well as safe living conditions. This article provides a detailed analysis of the electromagnetic field of a medium/low voltage transformer carried out using specialized simulation software. This type of research is also particularly important for those living in buildings with built- in transformers, as strong electromagnetic fields can pose a health risk. Through simulations, a better understanding and management of electromagnetic emissions is achieved, providing a safer and more comfortable environment for the occupants.
