The purpose of this article is to present the application of the sliding mode control and investigate its effectiveness when applied to a three-dimensional robotic manipulator model. The analysis is based on the application of the sliding mode control law for the PUMA 560 model, three degrees of freedom, through the development of a dynamic simulation model. The simulation results show the effectiveness of this proposed method for the automation of industrial applications, such as assembly, machining (deburring, trimming), and surface tracking (polishing). This technique provides a useful insight into the advantages of using sliding mode control laws in robotics applications. © 2023 IEEE.

This article supplies a proposed approach Neuro Fuzzy Controller (NFC)-Adaptive Backstepping Controller (ABC)-Space Vector Modulation (SVM) for a five-level NPC inverter-Double Stator Interior Permanent Magnet Synchronous Motor (DSIPMSM). This paper’s primary objective is to enhance DSIPMSM’s performance by the use of strong control using the proposed approach. Given its benefits—including high torque density, high efficiency, high power density, and minimal maintenance—DSIPMSM, have recently been the focus of much research. Using the input-output linearization approach and Lyapunov stability theory, asymptotically stable trajectory-following dynamics are demonstrated using nonlinear adaptive backstepping control. The use of fuzzy logic and intelligence-based controllers are increasingly being used to enhance traditional control’s performance and output. In addition, the fuzzy logic controller has a lot of flaws that are presently being fixed by the extremely effective NFC tool. The proposed method’s worth was demonstrated by the simulation results in terms of durability, effective tracking dynamics, precision, and good disturbance rejection with little ripple.

Gender identification software is becoming increasingly popular in the age of machine-to-machine interactions, as the need for person-aligned, effective, and ethical systems become more apparent. In this age of machine-to-machine interactions, automated gender identification software is becoming more popular. The bulk of the systems for gender identification that were examined used either textual or audiovisual data as input to determine their gender. Many different approaches to automatically detect gender based on traits gathered from people's bodies and/or behaviors have been suggested, and there are simply too many to include here. The accuracy of automated gender identification, on the other hand, has always been a topic of worry or a source of criticism. Initial face identification is accomplished by the use of the Haar Cascade face detection method, which is based on the Viola-J ones face recognition algorithm. Facial characteristics such as the eyes, mouth, and nose are then identified. Second, using the Viola-Jones face detection algorithm, the faces and facial characteristics such as the eyes, mouth, and nose are recognized, and the results are shown. In order to increase the accuracy of gender identification, adaptive filters are employed to reduce the amount of noise present before the detection process is carried out. The facial qualities that have been gathered are utilized as input or test data for the neural network, which is subsequently trained on these characteristics. It is intended that the neural network acquires the features of the genders and then functions as a classifier when it comes to detecting them. Instead of saying it another way, a neural network known as Keras is used for feature extraction and gender identification, which is free and open-source software. © 2023 IEEE.

In this paper, a compact ultra-wideband patch antenna is presented and discussed. The antenna, printed on Rogers RT5580, consists of leaf-shaped radiating element excited through tapered coplanar waveguide feed line, and semi-elliptical partial ground plane. It covers a frequency range starting from 2.8 to 15.1 GHz. The antenna prototype is fabricated, and a good agreement is obtained between the experimental and simulation results indicating that the proposed structure, having a reasonably compact size of 20x32 mm2 is suitable for a wide variety of applications due to its large operating frequency. © 2022 IEEE.

In this paper, four optical filter topologies based on metal–insulator–metal waveguides are proposed and the designed structures are investigated numerically using finite-difference timedomain method. Triangular-shaped adjunctions have been added to the filter structures to improve their transmission spectrum. These improved structures consist of air as the insulator and silver as the metal. The relative permittivity of metal has been described via the Drude,Drude–Lorentz, and Palik models. The first filter’s transmission spectrum shows an acceptable transmittance. In the second optimized filter, the transmission spectrum has been improved. The transmittance spectrum can be tuned through adjusting the edge of the triangle in these four optimized filters. As a result, the bandwidths of resonance spectra can be adjusted. The theory of such tapered structures will be investigated by the tapered transmission line and will be solved with the transfer matrix method. This method shows a better performance and higher transmission efficiency in comparison with the basic structures. On the other hand, the final filter has been chosen as the best one because of its hexagonal resonator. The main reason for having a better result is due to a longer interaction length in comparison with the circular resonator. This in turn creates much better energy coupling and results in higher transmission.

One-Sided Lipschitz (OSL) fractional order modeling is a top choice for solving the stabilization issue of nonlinear systems. Despite numerous studies on the subject, there remains a gap in understanding when it comes to fractional calculus. By providing a stabilizing strategy for a certain type of OSL fractional order nonlinear systems, this study fills the gap. A numerical example demonstrating the correctness of the suggested approach and demonstrating its efficacy for the tested class.

This paper introduces the concept of reliable nodes in neutrosophic soft graphs by evaluating path-based parameters. A reliable node is defined as one which is least susceptible to changes that are quantized by the indeterminacy and falsity values in a neutrosophic tuple. A new path measure called farness and three novel reliability measures which make use of the same are presented. Farness is defined in terms of a novel score function. The first, proximity reliability of a node, computes the farness of a node to its neighbours. The second, intermediate reliability of a node, computes the fraction of paths of minimal farness that pass through it. The third, crisis reliability of a node, is a hybrid of the two previously defined. It considers the farness of a node to its neighbours taking into account the farness of the neighbours to other nodes in the graph. © 2022. All Rights Reserved.

Negative coupling is widely used in microwave filter design, especially for filters with finite transmission zeros (TZs). Conventionally, negative coupling is physically realized by capacitive irises or electrical probes. When negative coupling is small, the capacitive iris size usually becomes very small or the electrical probes need to be carefully placed, the manufacturing and tuning of filters, as a consequence, is of great challenge. In this paper, a coupling structure based on groove gap waveguide (GGW) is proposed to implement negative coupling and applied to a cascaded quadruplet (CQ) waveguide filter. The simulated and measured results demonstrate that the GGW coupling structure can perfectly replace the capacitive iris to implement the desirable negative coupling while favorably easing manufacturing difficulties caused by small negative couplings and lowering sensitivity to manufacturing tolerance for waveguide filters.

In this work, we theoretically design a series of two-dimensional (2D) materials with eight stacked sublayers AlGeZ2 (or Al2Ge2Z4) (Z= N, P, and As) and explore their structural, vibrational, piezoelectric, electronic, and transport properties via first-principles prediction. It is demonstrated that AlGeZ2 monolayers exhibit high structural stability by analyzing their phonon dispersions and ab initio molecular dynamics tests. Further, we also examine the vibrational characteristics and Raman activity of AlGeZ2 by using the finite displacement technique. At equilibrium, AlGeZ2 monolayers are found to be semiconductors with a moderate bandgap. AlGeZ2 semiconductors exhibit superior mechanical features with 2D in-plane stiffness up to 382.83 N/m (AlGeN2). The piezoelectricity examinations indicate that we can consider AlGeZ2 as piezoelectric semiconductors with in-plane piezoelectric coefficient d11 ranging from −0.22 to −0.44 pm/V. Importantly, AlGeZ2 semiconductors exhibit very high electron mobility, up to 3.71×103 cm2V−1s−1 (AlGeAs2), which is suitable for applications in flexible nanoelectronics. © 2025 Elsevier Ltd and Techna Group S.r.l.
