The intense advancements in aerospace, industrial automation, and marine applications have underscored the need for compact, high-power density, and intensively efficient motors. This study addresses the impact of rotor yoke thickness on torque production by exploring distinct Halbach Array (HA) permanent magnet configuration in Axial Flux Permanent Magnet (AFPM) motor. Based on finite-element analysis (FEA), a comparative study between three different HA configuration is carried out to nominate the model having high torque. Although the unique magnetic orientation in each magnet segment of HA can enhance torque utilizing less rotor yoke thickness, the traditional manufacturing technique is not suitable for mass production. Therefore, to overcome this issue, a novel magnetizer consisting of magnetizing teeth including coil placed in a slot is designed. This innovative approach provides a cost-effective and efficient solution for commercialization of HA permanent magnet. © 2024 The Institute of electrical Engineers of Japan.

Inverter topologies for integrating a rooftop photovoltaic (PV) unit into a microgrid are becoming increasingly complex. This paper proposes a high-voltage boosting transformerless inverter (HVBTI) topology for enhancing such applications. The coupled inductor-based high voltage gain feature of the HVBTI configuration allows power to be delivered into the grid from a lower voltage PV source without using higher duties. In addition, HVBTI suppresses leakage current as the common connection shared between the -ve terminal of the PV source and the grid neutral point. In comparison to existing topologies, the HVBTI topology uses a compact pulse width modulation strategy to control only six controllable switching devices. Again, using lower-rated switching devices is more cost-effective while increasing reliability and efficiency. In a laboratory prototype of a 1 kVA grid integrated system, the proposed HVBTI configuration is validated, and the maximum efficiency of the HVBTI is estimated at approximately 95%. © 1972-2012 IEEE.

The maximal coding rate reduction (MCR2) objective for learning structured and compact deep representations is drawing increasing attention, especially after its recent usage in the derivation of fully explainable and highly effective deep network architectures. However, it lacks a complete theoretical justification: only the properties of its global optima are known, and its global landscape has not been studied. In this work, we give a complete characterization of the properties of all its local and global optima, as well as other types of critical points. Specifically, we show that each (local or global) maximizer of the MCR2 problem corresponds to a low-dimensional, discriminative, and diverse representation, and furthermore, each critical point of the objective is either a local maximizer or a strict saddle point. Such a favorable landscape makes MCR2 a natural choice of objective for learning diverse and discriminative representations via first-order optimization methods. To validate our theoretical findings, we conduct extensive experiments on both synthetic and real data sets. Copyright 2024 by the author(s)

Protecting equipment and objects from fire in warehouses and industry premises is essential due to a high number of people present, valuable equipment or inventory and possibly dangerous goods. It is mostly often conducted by using smoke and fire sensors along with extinguishing systems. Still, in facilities with valuable inventory and equipment, it is also necessary to protect equipment from damage caused by water. This paper proposes a multi-agent robotic fire extinguishing model consisted of autonomous robots divided into two groups: Patrol Robots and Fire Extinguishing (FE) robots, called PR-FER model. The main methodology of the PR-FER model is using small patrol autonomous robots as a surveillance robots that will first map the surveillance area, determine the patrol paths, and conduct surveillance according to the predefined schedule. They are equipped with the devices for detecting fire and high temperatures such as RGB, IR and Thermal Imaging cameras and various sensors. Furthermore, they will have high capacity batteries which will enable them a long autonomy. In case of a detection of too high temperatures and fire, patrol robots would map the dangerous location and call FE robots to extinguish it. The FE robots are more robust and heavier robots equipped with fire extinguishers. During the fire extinguishing procedure the patrol robots would notify the fire department and enable them a video streaming in order to get an early awareness of the situation on the field. © 2023 IEEE.

In recent years, relevant policies of rehabilitation medical care have been released successively, and the development of the medical industry and the construction of rehabilitation medical service system have been vigorously promoted from the macro policy level. However, there is still a large shortage of rehabilitation therapists at this stage, and there is obviously a shortage of supply in the rehabilitation medical industry. This research focuses on the current social problem of insufficient professional guidance in the rehabilitation medical industry, mainly for the lack of professional guidance in home rehabilitation training, using computer vision recognition technology, with the help of home computer equipment, to develop a set of suitable for community rehabilitation services and home rehabilitation training, operation easy recovery system. At the same time, the system design achieves the three goals of "low cost, high efficiency, and easy operation". While solving the social problems of difficult home rehabilitation training, it also reduces the treatment cost and space constraints of rehabilitation patients, so that home rehabilitation patients can receive professional and accurate rehabilitation training guidance at any time. © 2024, Taiwan Ubiquitous information CO LTD.

Smart Grids (SG) rely on Home Area Networks (HAN) and Neighborhood Area Networks (NAN) to ensure efficient power distribution, real-time monitoring, and seamless communication between smart devices. Despite these advantages, the use of public communication channels in HAN and NAN networks introduces critical challenges, such as vulnerability to impersonation, physical tampering, and scalability issues in resource-constrained environments. These issues compromise the stability, reliability, and security of SG environments. Existing protocols often fail to adequately address these challenges, particularly in ensuring resistance to physical tampering of supply lines and impersonation attacks. Additionally, they struggle to minimize the computation, communication, and energy costs associated with securing a resource-constrained SG environment. Therefore, we propose a robust key exchange and tamper-resistant protocol for HAN and NAN networks to address these limitations. The proposed protocol leverages the Physical Unclonable Function (PUF) mechanism to offer physical tampering resistance to smart meters. We validate our protocol formally using the Random or Real (RoR) model, which confirms its security robustness. Additionally, our informal security analysis highlights the protocol's resilience against impersonation, physical tampering attacks, etc. We analyze and compare the performance of the proposed protocol, which further demonstrates our protocol's effectiveness and security compared to competing protocols. Moreover, the proposed protocol achieves resource efficiency with 45.99% and 58.85% substantial reductions in computation overhead and energy overhead, respectively, compared to competing protocols. These results showcase the protocol's enhanced security and practicality for resource-constrained SG environments. © 2014 IEEE.

Aggregate planning is a crucial stage in the production process because it supports other processes. Careless production planning may cause production costs to spike sharply that hurts the company financially. This study explores the novel usage of particle swarm optimization (PSO) to discover a set of solutions among the objective of a multioptimization problem in aggregate production planning. The study uses a small home textile industry with complex production processes of school uniforms as a case study. The results show that the production cost difference between actual data and the proposed method is IDR330,670,000. Thus, PSO can solve the multi-site aggregate planning by reducing the company production cost. Copyright © Journal of engineering, Project, and Production Management (EPPM-Journal).
