Nowadays, mental-insulator-metal (MIM) waveguides are widely used in the design of optical plasmonic waveguides due to their superior ability to confine surface plasmons up to sub wavelength scale. This research proposes the design of series and parallel circuits using cascaded plasmonic Mach-Zehnder interferometers (PMZIs). Each PMZI employs a nonlinear arm to switch light across the output port via the insertion of the nonlinear Kerr material poly(2-methoxy-5-(28-ethylhexyloxy)-PPV). The proposed design is having footprint of 104 μm × 11 μm. The finite-difference time-domain method is used to study, design, and analysis all optical series and parallel circuit proposals. © 2022 Walter de Gruyter GmbH, Berlin/Boston.

In this paper, we propose a novel keyframe extraction extraction method based on the gray wolf optimization (GWO) algorithm, addressing the challenge of information loss in traditional methods due to redundant and similar frames. The proposed method GWOKConvLSTM prioritizes speed, accuracy, and compression efficiency while preserving semantic information. Inspired by wolf behavior, we construct a fitness function that minimizes reconstruction error and achieves optimal compression ratios below 8%. Compared to traditional methods, our GWO method achieves the lowest reconstruction error for a given compression rate, providing a concise and visually coherent summary of keyframes while maintaining consistency across similar motions. Additionally, we propose a template-based method for video classification tasks, achieving the highest accuracy when combined with pre-trained CNNs and ConvLSTM. Our method effectively prevents dynamic background noise from affecting keyframe selection, leading to significantly improve video classification performance using deep neural networks. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2024.

Multifunctional Carbon-Basalt hybrid composites against bird strike

引用

Materials Today: Proceedings 2023年 74卷 736-743页

作者： Joshi, Sarang Maharshi, Kumar Goyal, Nikunj Patel, Shivdayal Panwar, Ravi Department of Mechanical Engineering PDPM Indian Institute of Information Technology Design and Manufacturing Jabalpur Jabalpur India Department of Electronics and Communication Engineering PDPM Indian Institute of Information Technology Design and Manufacturing Jabalpur Jabalpur India

A bird strike is a common occurrence during an aircraft's takeoff and landing and is classified as a high-velocity impact, which can cause severe damage, a decrease in aerodynamic efficiency, and may lead to catastrophic failure. High strength composite materials are used in the wing structure to resist the bird strike. Stealth is an important factor for military aircraft, as it reduces the detectability range of the target. The current aircraft wing structure incorporates different systems to perform various functions, so a composite wing capable of performing multiple functions of providing stealth while retaining its existing properties is required. The need for sustainable green materials has shifted the focus to natural materials, and hybridization is the way to improve the properties. The current study proposes a multifunctional hybrid carbon-basalt-polyaniline composite for aircraft wing skin that can absorb electromagnetic (EM) waves while maintaining its mechanical properties. A polyaniline with 5 % weight was found to be optimal, as the prepared sample has a dielectric loss tangent of 2.1396. The hybrid composite was simulated against a bird strike and a maximum deflection of −48.54 mm was observed for a thickness of 1.2 mm. The deflection behavior of the prepared composite was compared to several works, and a thickness of 3.6 mm was found to be optimal for a deflection of −28.97 mm. For a curved leading-edge profile, the observed deflection for 1.488 mm thickness was 580 mm. An all-composite wing model was designed and proposed having two ribs, one spar, and two stringers all modelled in carbon-basalt-PANI composite showing the maximum center point deflection of 450 mm. The prepared multifunctional hybrid composite has a high potential for use in aircraft wing skins due to its reasonable mechanical properties, good EM wave absorption, and ability to withstand bird strike. © 2022

Differential Evolution (DE) is a potent stochastic evolutionary optimization algorithm garnering increasing research attention. Over the years, it has been found applicable in solving diverse real-world problems. DE employs mutation, crossover, and selection operators to guide populations toward optimal or nearly optimal solutions. However, the standard DE mutation strategies have found limitations in balancing exploration and exploitation effectively, thus prompting research into possible improvements. This study introduces a novel mutation strategy named Chebyshev Infused Chaos Mutation Strategy (CICMS). where a chaotic sequence partially guides the process of donor vector generation. Rigorous evaluations were conducted, comparing our modified DE against the standard DE and seven other metaheuristic algorithms, including Genetic Algorithm, Particle Swarm Optimization and Gravitational Search Algorithm. Experiments were performed using the challenging CEC 2014 benchmark functions, consisting of 30 objective functions. Results indicate substantial improvements in convergence speed and solution quality, highlighting the potential of our novel mutation strategy to enhance DE’s practicality in addressing complex optimization problems. This research contributes valuable insights to the dynamic field of optimization algorithms with implications for a wide range of applications. © 2024, Taiwan Ubiquitous information CO LTD.

IEEE Journal on Flexible Electronics 2025年第12期3卷 526-532页

作者： Zhang, Hanbo Lou, Yuqing Zhang, Zhihang Li, Yongfu Rokhan, Fakhrul Wang, Guoxing Zhao, Jian Shanghai Jiao Tong University School of Electronic Information and Electrical Engineering Shanghai200240 China Universiti Putra Malaysia Faculty of Engineering Department of Computer and Communication System Engineering Selangor Serdang43400 Malaysia

This paper proposed a fully LTPS-TFT-based bi-directional biomedical pixel interface with integrated a high linearity stimulator and a high-performance bio-potential sensing front-end circuit to amplify and digitize biological signals for high robustness data transmission. All circuits are designed and manufactured under a 3-μm LTPS process. We demonstrated the experiment in saline using the stimulator circuit to simulate stimulation inside the organism, achieving stimulation with different average currents under different duty cycles. The proposed front-end circuit has a gain of 40 dB. The referred input voltage noise of the entire signal chain is 86.2 μV/√Hz, and the ENOB is 9.13 bits at an input of 0.5 mVPP. Simultaneously conducting statistical testing on 20 chips has achieved a 1.05 dB SNDR standard deviation. Finally, we use a function signal generator to simulate the input signals of ECoG, ECG, and EOG, then use front-end circuits to read and reconstruct them to demonstrate that the proposed pixel interface can correctly read common biomedical signals for healthcare applications. © 2022 IEEE.
