Industry 5.0 is a new industrial strategy which increase interest in academia and professional in the last few years. The main difference according to the well-known Industry 4.0 is that Industry 5.0 is a human-centric strategy. Industry 5.0 gathers three basic concepts: people-oriented, environment-oriented, and resilience-oriented. However, many different studies show this concept in their own way. According to this literature gap, the aim of this study is to investigate the bibliographic analysis on the topic of Industry 5.0. The paper shows results on the most productive authors, the most relevant journals, the main keywords, and the most productive countries in the field of Industry 5.0.

Adjustable speed drives (ASDs) comprised of inverter-driven induction machines are now widely used in many applications. Design and analysis of such systems require accurate and efficient models of induction machines (IM) and voltage source inverters (VSI). Such studies are often done in real-time or offline multiple times for tuning/optimizing controller parameters. Usually, simulations of such systems are carried out using detailed switching models of VSI and qd IM models, which are readily available as built-in library components in many electromagnetic transient (EMT) simulation programs. However, detailed switching models of converters with qd IM models typically require interfacing snubbers and small time steps, making them computationally expensive. As an alternative, this paper extends the prior work and presents an efficient simulation method using the average-value model of VSI and decoupled constant-parameter voltage-behind-reactance (DCPVBR) model of IM. Simulation studies carried out using MATLAB-Simulink and real-time OPALRT5700 simulator demonstrate the computational advantages of the proposed method over existing approaches.

The article presents the results of experimental studies of erosive wear of selected steel grades depending on the angle of incidence of the abrasive stream. The following high wear resistance steels were selected for testing: Hardox 500, NC6 (1.2063) and 40HM (1.7225). NC6 (1.2063) and 40HM (1.7225) steels were subjected to heat treatment (hardening). The tests were carried out on a self-constructed stand, which allowed the impact of the abrasive stream on the sample at the indicated angle and under the specified pressure. A wide range of angles were tested: 10, 15, 30, 45, 60 and 90 degrees. The analysis of the obtained results allowed to indicate the material with the highest resistance to abrasive wear and to recommend it as the best material for working elements of mills and other devices exposed to intense erosive wear.

Widespread demand for product customization has led to the expansion of utilizing product configurators. Greater flexibility in product design and manufacturing are one of the main parts of the production process that could be impacted with this approach. Mass customization represent a manufacturing approach that combines the adaptability and customization of products with the rational costs of mass production. The aim of the paper is to demonstrate potential mass customization applications using product configurators while outlining benefits and limitations that could occur. Product configurators enable organizations to produce numerous customized items while simultaneously maintaining control over the design and manufacturing processes. On the other hand, customers have an opportunity to select from a variety of features to design a product that is adjusted to their requirements.

This paper presents the hardware implementation of a stable wireless adaptive remote control point-to-point link, based on the nRF24L01+ PA/LNA transceiver module. On the transmitter and receiver side, a microcontroller integrated circuit STM32F103C8T6 has been used to implement appropriate adaptive algorithms that enable a synchronized change of the communication channel in case of interferences. The link stability has been verified experimentally in real conditions, in the presence of random interferences. The presented experimental results show how interferences affect the stability and range of the presented communication link.

We present a theoretical prediction of a novel, nonEIT, mechanism for the achievement of a transparency window. It relies on an intrinsically nonlinear (soliton type) mechanism which may be exploited for the production of slow light, which may appear in a photonic band-gap structure: the infinite coupled cavity array (CCA), filled with two-level systems - qubits. Each cavity contains a single qubit. The most important prediction is substantial dependence of the pulse transparency on its width. In particular, the medium is opaque for very short pulses with carrier wave frequency below the photonic gap. When the pulse width exceeds the critical one, a twin transparency window separated by a finite band gap appears in the SIT pulse dispersion law. Both low-frequency TW and the SIT pulse band gap lie entirely within the polaritonic band gap.

Deep learning models for image classification are typically trained under the "closed-world" assumption with a predefined set of image classes. However, when the models are deployed they may be faced with input images not belonging to the classes encountered during training. This type of scenario is common in remote sensing image classification where images come from different geographic areas, sensors, and imaging conditions. In this paper we deal with the problem of detecting remote sensing images coming from a different distribution compared to the training data – out of distribution images. We propose a benchmark for out of distribution detection in remote sensing scene classification and evaluate detectors based on maximum softmax probability and nearest neighbors. The experimental results show convincing advantages of the method based on nearest neighbors.

With the progress of technology and mankind, demand for different job positions has emerged. Reports indicating various new job types in the last decade are continuously published, giving us perspective on where we were a decade ago and where we are now. Most of the jobs are created around new technologies, yet not exclusively as jobs within technology production or usage (e.g., machine learning engineers, data scientists, app developers, etc.), but also as a type of jobs built atop of new technologies (e.g., social media manager, podcast producer, content moderator, etc.). With new job types, there is a gap between qualified employees and employers demands created. Taking into consideration trends that we have seen in the last years, more and more new job types will be created, and we can predict that this gap will become larger as time passes.

This paper presents an analytical method for designing controllers within a modified parallel cascade control structure for stable, integrating, and unstable primary processes considering robustness and the sensitivity to measurement noise. The secondary process is assumed to be described by the stable, non-integrating first-order plus dead-time (FOPDT) model. In the proposed design procedure, using the complementary sensitivity approach, the secondary controller H2(s) is first designed, which is then decomposed into two controllers C2(s) and F2(s). Then, the primary controller H1(s) is determined and further decomposed into two controllers C1(s) and F1(s). Finally, the high-order/non-rational transfer function of the controller C1(s) is suitably approximated to obtain a low-order controller. Alternatively, for stable primary processes with dominant time delay, the realization of the full controller C1(s) without any approximation is proposed. The trade-off between performance and robustness of the closed-loop system is achieved by two user-specified parameters λ and β for the secondary and primary control loops, respectively. The effectiveness of the proposed design method is analyzed by simulations on typical representatives of industrial processes.
