One of the most significant and difficult challenges in solar systems is determining the maximum power point. This process becomes more difficult when the array of solar modules is subjected to non-uniform shade. A unique hybrid maximum power point tracking (MPPT) approach is presented in this research. The suggested approach, cuckoo search–perturb observe, is created by combining the traditional perturb & observe (P&O) and cuckoo search algorithms (CSPO). A hybrid algorithm has been developed to capitalize on the benefits of both algorithms while overcoming their respective disadvantages. The proposed algorithm attempts to incorporate the most prominent aspects of both algorithms while also attempting to address the drawbacks of both algorithms and improving the accuracy of the new approach by resolving the issue of P&O getting stuck on local maxima during non-uniform irradiance and reducing the resource-intensive approach of cuckoo search by limiting its number of iterations. Furthermore, the suggested approach locates the maximum power point using just voltage sensors, decreasing sensor requirements. The simulation findings for maximum power point tracking performance are also presented. © The Institution of Engineers (India) 2024.

The increasing global prevalence of diabetes necessitates the development of accurate, reliable, and miniaturised glucose sensing technologies. Microwave-based sensors offer a promising alternative to conventional electrochemical methods due to their less invasive nature and real-time monitoring capabilities. However, previous microwave glucose sensors have often lacked comprehensive validation, limiting their practical usability. Many existing studies rely on simplified simulations without detailed parametric studies or fail to establish a strong correlation between theoretical models and experimental results, resulting in discrepancies in sensor performance. This study introduces a Cross-Slot Substrate Integrated Waveguide (CSSIW) sensor that overcomes these limitations by implementing a rigorous multi-level validation approach, including analytical modeling, full-wave electromagnetic simulations, and experimental verification. The sensor’s X-slot structure enhances electric field concentration, significantly improving sensitivity while maintaining a compact form factor (13×9 mm). Through eigenmode analysis and parametric studies, the sensor’s resonant frequency shift is optimised to detect glucose concentration variations with high precision. Experimental validation using glucose solutions at physiological concentrations (20–200 mg/dL) demonstrates a sensitivity of 0.563 MHz/(mg/dL), closely aligning with simulated results (0.415 MHz/(mg/dL)), confirming its accuracy and robustness. Compared to previous works, this study addresses prior shortcomings by providing a detailed investigation of field interactions, quality factor evaluation, and environmental dependencies, ensuring a comprehensive understanding of the CSSIW sensor’s performance. The findings confirm that the proposed sensor achieves low insertion loss (1.13 dB), strong impedance matching (-18.7 dB return loss), and full physiological range coverage, making it a promising candidate for next-generation g

Noise and Vibration Worldwide 2023年第2-3期54卷 108-121页

作者： Hasanlu, Mojtaba Siavashi, Mostafa Bagheri, Ahmad Department of Dynamics Control and Vibrations Faculty of Mechanical Engineering University of Guilan Rasht Iran Department of Mechanical Engineering Babol Noshirvani University of Technology Babol Iran

This paper investigates metamaterial functionally graded plates with quasi-zero stiffness resonators. This way, the governing equations of free vibrations and the mode shapes are obtained using the assumed mode method. The free vibrations analysis of the metamaterial functionally graded plates is then performed using finite element analysis. The objective of the current paper is to present an FG metamaterial plate structure to attenuate its mode shapes. Various resonators’ arrangements on the FG plate evaluate the best arrangements. This paper shows that the proposed metamaterial attenuates the corresponding shape modes for the first nine natural frequencies. © The Author(s) 2023.

Czech Technical University in Prague Faculty of Mechanical Engineering Department of Automotive Combustion Engine and Railway Engineering Technicka 4 Prague 6 Czech Republic Czech Technical University in Prague Faculty of Mechanical Engineering Department of Instrumentation and Control Engineering Technicka 4 Prague 6 Czech Republic

The paper deals with the design of a sensor system for the detection of lateral position and angle of attack of wheelsets relative to the track. The goal is to determine the type and placement of sensors mounted on the axle-box so that, with their use, the position of the wheelset towards the track can be contactless detected while the vehicle is running. Such a system can be used during vehicle testing according to EN 14363 and potentially also in active wheelset steering systems. To determine wheelsets’ position is a complex task with several degrees of freedom, because not only the angle of attack and the lateral position of the wheelset changes, but also the vertical position of the sensor above the top of the rail and the shape of the rail head are variable. In the first phase of the project, suitable industrial sensors were selected in terms of dimensions, measured ranges, tolerance to acceleration and other environmental impacts. Three sensors were selected, and their output characteristics were measured depending on the vertical and lateral distance from the rail. Based on the measured characteristics, the type, number, and arrangement of the sensors will be proposed. The paper focuses mainly on the choice of appropriate types of sensors, the description of the test equipment and the measured characteristics of the sensors. © 2024 Kaunas University of Technology.

This paper describes an electronically controllable floating lossless inductance simulator circuit implemented with only off-the-shelf available integrated circuits, namely LT1228 and operational amplifier (OA). The proposed design consists solely of two LT1228s and a single OA. By using an active element named LT1228, the equivalent inductance can be tuned electronically with depended on the externally supplied current applied to LT1228. The proposed simulator imposed just one component matching restriction that required the equality of two transconductances. It is easily attainable with a simple current mirror. The worthiness of the proposed floating inductance simulator has been proven and applied to the construction of the 2nd-order RLC highpass/bandpass filter as an application. PSPICE simulations are used to investigate the characteristics of the proposed simulator and its filter realization. © 2024 IEEE.

This paper presents the development of a sensing module for analyzing the concentration of disinfectant alcohol commercially available in Thailand during the Covid-19 epidemic situation to ensure the ingredients and percentage concentration by focusing on simplicity, low cost with reliable performance. Under the basic physical structure of the capacitance change [1]-[5], it consists of a New Sensor Module developed to fully interface with the small capacitance to DC converter for capacitive sensor [2] model. Inside the sensing structure, there were 2 modules of metal conductors. Each conductor was 3 mm. thick, placed in parallel with a fixed distance between the module of 1 mm. The cross-sectional areas of the plates of those two modules were different in order to compare the efficiency of the detector developed. The cross-sectional areas of the plates of Module A and B were 4 cm2 and 1 cm2, respectively. Experiments were performed with 3 concentrations of alcohol, 65%, 70% and 75%, to enhance the concentration detecting performance of the sensing module developed. The signal conditioning was generated from a small capacitance to DC converter for capacitive detection with a frequency of 100 kHz, which was the most suitable frequency for exciting the capacitance change which was the capacitive reactance of the alcohol used in this study. From experiments, it was found that the sensing module with a small cross-sectional conductive material would provide more accurate results in terms of linearity and repeatability. The errors were less than 2.72% compared to the module with a large cross-sectional conductor material which would have an error up to 4.73%. © 2024 IEEE.
