This paper proposes a high-boost power converter for renewable energy systems. The suggested converter exhibits a simplified structure by replacing a diode in the switched-inductor cell with an active power switch to reduce the total voltage stress on the semiconductor device, get cost reduction, and improve efficiency. Additionally, the common ground feature inherent in the introduced topology expands its potential for renewable energy applications. Finally, the simulation verifications are performed using PSIM software to confirm the effectiveness of the suggested approach, and a detailed comparison study between the basic switched-inductor converter and the suggested converter is also presented.

Although its advantages of handling input uncertainties and noises, Type-2 Fuzzy controller faces the challenge of the trial-and-error process for evaluating so many control parameters. To overcome this issue, an Elman neural network with the adaptation laws was proposed to make a hybrid model that leverages the expressive power of Type-2 Fuzzy Logic and the predictive capability of Elman Neural Networks to capture temporal dependencies. The adaptation laws employ the gradient descent method to dynamically update network parameters in realtime. To demonstrate the effectiveness and practical utility of the proposed control system, numerical simulation results are presented, specifically on its performance in trajectory tracking control for cart inverted pendulum systems.

The bottleneck networks of the progression of vehicular traffic need an exhaustive cognizance and bits of knowledge of the factors that cause congestion, which characterizes the second and spot of traffic breakdown. The organization becomes clogged because of the rising number of vehicles out and about. Many exploration studies have been directed to resolve the issues. Functional examination, specifically the plan, investigation, and the board of the traffic stream dynamic, appears to esteem re-enactment and demonstrating to the connected difficulties. To reduce gridlock for a smooth and low-thickness traffic stream framework, this work focused on a reproduction model for vehicular traffic stream. In this review, a congestion-mindful message (CAM) in view of vehicle ID is introduced for guide signals in a vehicle setting. The overhauled vehicle ID-based investigation model is introduced at first at the Macintosh convention of the vehicle climate. The model loads the randomized back-off numbers chosen by the autos taking part in the back-off strategy utilizing the vehicle ID implanted in every one of their one-of-a-kind CAMs. Because of the indistinguishable back-off number, this outcome in the recognizable proof of a vehicle ID-based randomized ease-off code, which brings down the gamble of a crash. In this review, traffic thickness-based congestion the board calculation (TDCCA) using machine learning is proposed. While only one-fourth of the congestion window is utilized in the trial, the better numerical method beats the prior work's general parcel dormancy. To expand the viability of the model boundaries, the exploration utilizes the congestion the board method that changes the pace of CAM broadcast across the host controller.

Progressive multifocal lens is a typical optical free-form surface element. Compared with the traditional spherical lens, the diopter of the far-view area and the near-view area of the progressive multifocal lens are different, and the diopter gradually changes smoothly in the intermediate transition area. The wearer can continuously and clearly see objects at different distances. However, due to the complex surface structure of the progressive multifocal lens, the machining cost is high, so its application is limited. In this study, a new machining method named single-point diamond ultra-precision turning technology based on fast tool servo (FTS) is proposed, which can achieve the fabrication of progressive multifocal lens with high finished surface quality and low manufacturing cost. In this paper, the three-dimensional geometric model of progressive multifocal lens surface is converted into equidistant spiral line according to the principle of turning non-rotational symmetric curved surface. In addition, the effect of spindle speed, feed rate and cutting depth on the finished surface quality of the progressive multifocal lens are investigated. The experimental results show that the proposed method is feasible for the sustainable and high-efficiency fabrication of progressive multifocal lens.

Flexible sensor array has attracted widespread attention and brought many opportunities in future applications, such as electronic skin, human–machine interactions, and healthcare monitoring. In this study, we report the flexible triboelectric sensor array (TSA) with cross bar configurated sensing units for human-machine interaction. Bead-on-string sacrificial structure is fabricated by 3D printing directly and optimized based on experimental and numerical studies, and therefore affords excellent performance in constructing the electrode lines for TSA. With the especially patterning design and optimization, the number of data channels in TSA is reduced, and high output performance can be achieved effectively. Meanwhile, TSA platform exhibits excellent durability, reliability, waterproofness, and presents the ability in real-time sensing and locating of keystroke position and trajectory tracking. For application scenarios, a TSA-based intelligent digital controller is established for importer identification based on temporal perceiver network. We use this controller in robot manipulation to control gestures of both rigid manipulator and soft pneumatic actuator conveniently. The proposed TSA in this work opens a new route in promising applications in security identification, robot manipulation and artificial intelligence. © 2023, The Authors. All rights reserved.

In this paper, an experimental study on the effects of the hydraulic diameter on heat transfer and fluid flow characteristics in fully developed turbulent flow in a rectangular channel with one wall (upper) exposed to the heat flux is presented. The hydraulic diameter of the channel was varied by using a wooden block mounted on the bottom wall of the channel. The block to channel height ratio, Hb/H was kept at 0.6, the block to channel length ratio Lb/L was kept at 1, and the block to channel width ratio, Bb/B was varied from 0 to 0.6. Four cases were investigated in this study for Reynolds number ranging from 6, 000 to 20, 000. The results of this investigation demonstrate that, the pressure drop is increased with decreasing hydraulic diameter and heat transfer coefficient is decreased with decreasing hydraulic diameter. © 2020 IEEE.

Producing high-quality surfaces from hard and brittle metals presents a formidable challenge that calls for a meticulous machining strategy and an effective cutting tool. The mechanism of tool failure, chip formation behavior, and micro-morphology of the machined surface are crucial factors in determining a correlation between the used parameters and the machined surface quality. Among the metrics employed to assess the effectiveness of the tool. However, the determination of optimum machining parameters requires the repetition of precise experimental investigations with every change in the cutting conditions. The current research work proposes a set of suggestions for choosing the optimal tool parameters based on the micro-morphological characteristics of the tool and the machining performance indicators. A WC-Co ball end mill tool was used for the machining of an H13 tool steel workpiece to establish the relationship between changes in tool geometrical parameters and the machining performance indicators. Tool geometry with a rake angle of 3°, a clearance angle of 10°, and a helix angle of 32° was found to have the least wear band length at 56 μm. Moreover, the impact of tool geometry on the quality of the surface produced through machining was also investigated. © 2023 The Authors

For the dynamic reconfiguration of the distribution network when distributed generation are connected to the distribution network, a dynamic reconfiguration model of distribution network with on-load tap-changing transformer and static var compensator is proposed. First, Monte Carlo simulation method is used to form curve of wind/photovoltaic power output. Then, a dynamic grid reconfiguration model is established with the goal of minimizing power loss and voltage distribution. And, an improved NSGA-II algorithm integrated with constraint handling technique is proposed to solve the model. Finally, take the IEEE 33-bus system as an example for simulation, and the results show that the model can reduce system operating costs while improving system power quality. © 2020 IEEE.

There has been substantial scientific experimental research undertaken with the aim of determining factors that contribute to club-head speed while few on effects of club-head speed on drives, irons shot and putts in the game of golf. However, analysis of club-head velocity for an effective greenside bunker shot has not, and identification of associated key features for evaluation to obtain performance index relative to professional golfers (PG). Data from twenty-two (22) golfing subjects were analyzed through mathematical model that was applied at club-head peak velocity. For an effective greenside bunker shot, results indicated that PG delivered very high club-head speed at impact, low handicap golfers (LHG) delivered high club-head speed while novice golfers (NG) had low club-head speed. Result also showed that optimized performance index (OPI) value increased as the golfer's handicap index increased dramatically relative to PG golfers. The result of this study may serve as a novelty to the scientific analysis of an effective greenside bunker shot peak velocity and identification of golfer's performance index for skills enhancement through proper training guidelines. © 2020 IEEE.
