Solving time-varying linear equations is a com-mon challenge encountered in engineering and science. The development of neural dynamic systems has led to the creation of various feedback neural nets that effectively solve continuous time-varying linear equations. In this context, reciprocal Zhang neural net (RZNN) was developed, which is focused by this work, providing an explicit inverse-free continuous model for solving time-varying linear equations. However, the continuous model often struggle with noise interference, e.g., Gaussian noise, during the solving process. This paper enhances RZNN model with an integral reinforcement term to improve robustness of the explicit continuous models with noisy conditions. Furthermore, we optimize the RZNN solving process, making it easier for implementation in circuit systems and numerical simulations. © 2024 IEEE.

This study proposes an approach for robust localization with low computational cost in autonomous vehicles. We introduce EKF localization that combines NDT and DR. To estimate the uncertainty due to the real environment of NDT, we utilize multiple searches from many initial positions. Because multiple searches increase processing time, we limit the arrangement of initial positions based on the Hessian matrix of the NDT score function. The initial position arrangement according to the Hessian matrix is based on the direction in which error is likely to occur. This allows us to achieve real-time uncertainty estimation within a LiDAR period of 10Hz. Moreover, we propose hybrid correspondence NDT (HC-NDT) to reduce the computational cost of each search. HC-NDT reduces unnecessary correspondences between query points and ND voxel in neighbor search. In the convergence evaluation, HC-NDT reduced the processing time and maintained the accuracy compared to NDT with multiple correspondences. In the localization evaluation, our EKF localization with HC-NDT and our real-time uncertainty estimation suppressed errors within 0.3 m in challenging environments for NDT. The execution time of our uncertainty estimation with HC-NDT was reduced by up to 50 % compared to conventional NDT. © 2024 IEEE.

In previous studies, we have proposed the attacker's touch detection method in fingerprint authentication using high-frequency intra-body propagation characteristics to detect attacks in that an attacker holds the user's finger/wrist and presses the user's finger to a fingerprint scanner. However, the previous method used a wide range of frequency bands from 300 kHz to 10 MHz, and this caused problems in the circuit scale, cost, and size of the device in development for practical use. Therefore, we searched effective frequency bands and applied K-nearest neighbor with data augmentation in this study. As results, we achieved a 99.1 % touch detection rate with a single frequency and a 99.9 % touch detection rate with a combination of two frequencies. We achieved a significant reduction in the frequency bandwidth of the propagation characteristics. © 2023 IEEE.

Conventional power generation methods have led to adverse environmental impacts. Thus, the need for a strategic transition to alternative energy sources arises. This study presents a comprehensive approach to sustainable solar energy deployment using multi-criteria decision-making (MCDM) techniques. The research aims to identify suitable sites for utility-scale solar photovoltaic (PV) installations, estimate potential energy output, and assess solar PV deployment’s environmental and economic impacts. The methodology integrates analytic hierarchy process (AHP), fuzzy logic, and geographic information systems (GIS) to evaluate land suitability across four scenarios. The analysis considers technical, economic, environmental, and social factors, including solar radiation, proximity to infrastructure, land use, topography, and stakeholder opinions. Results reveal that Scenario 1 analytic hierarchy process multi-criteria-decision-making (AHP-MCDM) identified 2824.1 km2 of suitable land, while the combined approach in Scenario 3 yielded 666.9 km2. The study estimates potential annual energy generation ranging from 19.69 to 109.15 GWh/km2/year, depending on the scenario and solar PV technology used. Environmental impact assessments indicate potential annual CO2 emission reductions of up to 51,365.84 tons, with associated cost savings of US $3.28 million. The research provides valuable insights for policymakers and investors, highlighting 16 optimal sites for utility-scale solar farm development across Jamaica, with the most promising in the Westmoreland, Manchester, and St. Mary parishes. These findings contribute to Jamaica’s renewable energy goals and offer a replicable, sustainable solar energy planning framework in similar geographical contexts. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.

The objective of this paper is to develop a robot system that can transmit the video taken by the drone to the computer in real time, use YOLO to recognize the image of pedestrians, and enable the ground robot to plan the path to avoid pedestrians. External sensors, such as laser range finders (LRF) and CCD cameras, are often used on mobile robots. As we all know, these sensors are susceptible to occlusion. Therefore, even if the mobile robot avoids the pedestrian in front of it, it is likely to collide with other pedestrians that cannot be detected due to occlusion. In this study, we used a drone to shoot videos at high altitudes, transferred the videos to a computer, used YOLO on the computer to perform image recognition of pedestrians around the robot, and passed the recognition results to ROS, which enabled it to plan a path to avoid pedestrians around it. As a result, showed that the videos shot at high altitudes could effectively identify pedestrians around the robot after being recognized by YOLO. © 2025 IEEE.

DNS over HTTPS (DoH) enhances user privacy by encrypting DNS communications over HTTPS instead of plaintext. When all DNS messages are sent in plaintext, DNS queries can be examined and domain filtering applied if the queried domain name is identified as a phishing site or other such undesirable site. However, if DNS messages are encrypted over HTTPS, it can create many problems for network administrators. This paper proposes a method for detecting DoH communications from only non-encrypted information on a middlebox between user and resolvers by exploiting the fact that users always send a DNS query before they access a new domain. The middlebox can also identify the destination of the detected DoH traffic so that network administrators can recommend users to send DNS messages to a local DoH resolver with domain filtering instead of sending them to an open DoH resolver. In experiments to detect DoH communications during real communication from a web browser we achieved detection accuracy rates reaching 100% under certain parameters when the number of access IP addresses exceeded 350. To confirm the accuracy and generalizability of our experiments, the proposed method was also applied to captured HTTPS traffic data involving different web browsers and different DoH resolvers with an almost identical level of detection accuracy. © 2023 IEEE.

Due to the recent expansion in the generations of the communications systems, it is utmost priority to transmit a large amount of data over a wideband frequency spectrum. For this single ultra-wideband (UWB) antennas are the prime choice as compared to the multiple narrow band antennas. A modified pentagonal fractal patch antenna with a modified ground plane covering ultra-wideband has been proposed. The antenna has a compact size of 25 mm × 25 mm × 1.6 mm with peak gain of 2.2 dB. The UWB coverage of the design is achieved by implementing modified co-planar ground, modified fractal geometry and coplanar feed. The proposed design possesses the significant resonance and radiation performance with very compact size on low-cost substrate while covering the whole UWB. Finally, the simulated resonating and radiation characteristics have been validated with the measured characteristics of the fabricated prototype and the results are quite promising. © 2024 Informa UK Limited, trading as Taylor & Francis Group.

The manipulation of deformable linear objects (DLOs) by robots is challenging because of the complexity of modeling DLO dynamics. Although previous studies generally employed physical models and data-driven approaches to simulate DLO deformations, only a few studies have considered the contact of DLOs with the environment. In this study, we propose a framework integrating differentiable simulations with neural networks (NNs) to generate manipulation trajectories that avoid contact and achieve the goal shape. First, we implement a differentiable simulation to simulate the deformation and interaction of DLOs via position-based dynamics. Thereafter, we utilize the backpropagation of losses from the differentiable simulation to optimize the parameters affecting the deformation of DLOs in the simulator and explore an ideal manipulation trajectory for the task via an NN controller. The simulation and real-world experimental results reveal that the proposed method can generate valid manipulation trajectories from offline learning, which can also function well in real-world applications using the optimized parameters. © 2023 IEEE.
