The research paper explores the feasibility of employing the Prony parametric approximation technique for predicting time series data, with a particular emphasis on Earth rotation parameters. These parameters encompass the angular displacement of the Earth's pole axis, which are pivotal for comprehending and forecasting the Earth's rotation. The study utilizes a dataset that includes these specific parameters to evaluate the Prony method's effectiveness in forecasting. The outcomes of this method's application, which vary based on the algorithm's parameters, are thoroughly examined. This examination not only illuminates the method's predictive capabilities but also investigates how different parameter settings impact forecast accuracy. The findings underscore the Prony method's potential as a valuable instrument in the realm of time series forecasting, especially in the context of Earth rotation studies. This investigation contributes to a deeper understanding of time series analysis techniques and their applications in geophysics and related fields. The paper further discusses the implications of these findings for both theoretical and practical applications in Earth sciences. The research also highlights the importance of further studies to optimize the Prony method's parameters for maximum forecast accuracy. This could pave the way for more precise predictions in geophysical phenomena, benefiting a wide range of scientific and technological endeavors. © 2024 IEEE.

Uninterruptible power supply devices are widely used in protection facilities. It is necessary to ensure stable operation without power supply during design or redevelopment of the system. At the same time, there is no generally accepted algorithm for calculating battery parameters that are optimal in terms of the ratio of cost and discharge time. This problem is usually solved by using additional batteries, which increases the cost of the system. We suggest using the results of battery tests to optimize their amount in an uninterruptible power supply device. A test bench has been developed that allows you to adjust the load current. Three 12V rechargeable batteries with a Capacity of 12, 17 and 26 Ah were tested. The results showed that when the load current is increased by 20% and 30%, the battery life with Capacity 12 Ah is reduced by 50%. Batteries with a Capacity of 17 Ah and 26 Ah are reduced by 20% and 10%, respectively. It is concluded that when using batteries with a Capacity of 17 and 26 Ah, it is possible to increase the load current. The results obtained make it possible to more accurately calculate the required battery capacity for an uninterruptible power supply device and optimize their amount. © 2024 IEEE.

Phase-Shift Algorithm for Two Nonorthogonal Interferograms 3

Phase-Shift Algorithm for Two Nonorthogonal Interferograms

引用

3rd IEEE International Conference on Problems of Informatics, Electronics and Radio engineering, PIERE 2024

The phase step method is widely used to analyze interferograms and extract the phase distribution from them. Its limitation is the large number of interferograms required for this purpose. The minimum number is three interferograms. This paper describes a general analysis algorithm that requires only two interferograms, the phase shifts between which may not be orthogonal. The idea of the paper is to obtain an additional interferogram by transforming a two-dimensional elliptical cross section that is formed by the two interferograms into a threedimensional cross section with respect to the base of some spatial cylinder. After determining the parameters of the ellipse, a projection vector parallel to the center axis of the cylinder is found. Then the two-dimensional section is projected onto a three-dimensional plane perpendicular to the center axis of the cylinder. Each of the projections of this plane onto the coordinate planes forms one of the interferograms. After obtaining three interferograms, phase demodulation was performed using a three-point algorithm. The RMS error of the phase calculation was 0.015 radians. © 2024 IEEE.

Unsafe behaviour is a leading cause of death or injury in the workplace, including many accidents. Despite regular safety inspections in workplaces, many accidents occur as a result of breaches of occupational health and safety protocols. In these environments, despite efforts to prevent accidents and losses in hazardous environments, human error cannot be completely eliminated. In particular, in computer-based solutions, automated behaviour detection has low accuracy, is very costly, not real-time and requires a lot of time. In this study, we propose Unsafe-Net, a hybrid computer vision approach using deep learning models for real-time classification of unsafe behaviours in workplace. For the Unsafe-Net, a dataset is first specifically created by capturing 39 days of video footage from a factory. Using this dataset, YOLO v4 and ConvLSTM methods are combined for object detection and video understanding to achieve fast and accurate results. In the experimental studies, the classification accuracy of unsafe behaviours using the proposed Unsafe-Net method is 95.81% and the average time for action recognition from videos is 0.14 s. In addition, the Unsafe-Net has increased the real-time detection speed by reducing the average video duration to 1.87 s. In addition, the system is installed in a real-time working environment in the factory and employees are immediately alerted by the system, both audibly and visually, when unsafe behaviour occurs. As a result of the installation of the system in the factory environment, it has been determined that the recurrence rate of unsafe behaviour has been reduced by approximately 75%. © The Author(s) 2024.

Early diagnosis of psychological disorders is very important for patients to regain their health. Research shows that many patients do not realize that they have a psychological disorder or apply to different departments for treatment. The detection of hidden psychological disorders in patients will both increase the quality of life of patients and reduce the traffic of patients who apply to the wrong department. This study aimed to determine whether patients who consult a physician for any reason need psychological treatment. For this purpose, the relationships, and similarities between the sentences of previous psychiatric patients and the sentences of newly arrived patients were analyzed. Domain-based trained ELECTRA language model was used to detect sentence similarities semantically. In the study, the dialogues of patients with physicians in 92 different specialties were analyzed using the MedDialog dataset, which consists of online physician applications, and the DAIC-WOZ dataset. As a result of the experiments, 90.49% success was achieved for the MedDialog dataset and 89.36% for the DAIC-WOZ dataset. With the proposed model, patients in need of psychological treatment were identified and the medical departments where psychological problems were revealed the most were determined. These divisions are Neurology, Sexology, Cardiology, and Plastic Surgery, respectively. With the findings obtained, complications caused by psychological problems and types of diseases that are precursors to psychological disorders were determined. To the best of our knowledge, this article is the first study that aims to analyze all psychological illness instead of focusing on any of the psychological problems (depression, OCD, schizophrenia, etc.) and validated by electronic health records. © The Author(s) 2024.

FSIW Cavity-Based Self-Packaging Filtering Slot Antennas with Wide-Stopband and High Frequency Selectivity

This article proposes a novel design approach for miniaturized, highly selective, self-packaged, and wide-stopband filtering slot antennas based on C- and T-type folded substrate integrated waveguide (C-/T-FSIW) cavities. Firstly, two forms of FSIW cavity are explored and analyzed. A new coupled C-type half-mode FSIW (C-HMFSIW) cavities are developed. A filtering antenna is proposed, employing a C-HMFSIW cavity for feeding and a slot-loaded C-FSIW cavity for radiation. By introducing cross-coupling between different resonators, a radiation null (RN) is achieved. To further enhance bandwidth and frequency selectivity, a new antenna configuration is developed using a C-HMFSIW cavity for feeding and a slot-loaded T-FSIW cavity for radiation. After loading the radiation slot, the T-FSIW cavity serves as two parts: one as the main radiator and the other as a parasitic radiator opposite to it. This configuration increases antenna bandwidth and generates an additional RN. Interestingly, adjusting the position of the radiation slot allows the RN to switch between the upper and lower stopbands. The antennas proposed in this work exhibit good stopband performance and compact size. Three filtering antenna prototypes are designed, fabricated, and measured, showing consistent results between measurements and simulations. © 1963-2012 IEEE.

We present a solution for locating the source, or maximum, of an unknown scalar field using a swarm of mobile robots. Unlike relying on the traditional gradient information, the swarm determines an ascending direction to approach the source with arbitrary precision. The ascending direction is calculated from field strength measurements at the robot locations and their relative positions concerning the swarm centroid. Rather than focusing on individual robots, we focus the analysis on the density of robots per unit area to guarantee a more resilient swarm, i.e., the functionality remains even if individuals go missing or are misplaced during the mission. We reinforce the algorithm's robustness by providing sufficient conditions for the swarm shape so that the ascending direction is almost parallel to the gradient. The swarm can respond to an unexpected environment by morphing its shape and exploiting the existence of multiple ascending directions. Finally, we validate our approach numerically with hundreds of robots. The fact that a large number of robots with a generic formation always calculate an ascending direction compensates for the potential loss of individuals. © 2024 IEEE.

The pulp and paper industry faces significant en-vironmental challenges, such as air pollution, greenhouse gas emissions, and wastewater discharge, requiring smarter and more sustainable operations. Regulatory bodies are imposing stringent measures to mitigate these impacts, prompting the industry to adopt sustainable practices and technologies. Life Cycle Assessment (LCA) models are crucial in this effort, pro-viding a comprehensive evaluation of environmental impacts and aiding decision making for sustainable manufacturing. However, organisations prioritise the confidentiality of their sensitive data, which can hinder collaborative efforts and LCA calculations. This paper addresses organisational requirements for improving confidentiality, tamper-proof data transfer, and ensuring data sovereignty. The ongoing proof-of-concept introduces a novel approach in LCA, employing Secure Multiparty Computation (SMPC) and data spaces to enable confidentiality-preserving LCA. Our solution ensures data sovereignty and accurate LCA calculations, promoting sustainable practices across the value chain. This paper lays the foundation for a collaborative data platform that meets the critical needs of confidentiality, security, and sustainability in the process manufacturing industry. © 2024 IEEE.
