The existing route planning algorithms are directly applied to the remote text{TF}/text{TA} route planning of large and medium-sized fixed wing aircraft, and cannot simultaneously meet the requirements of efficiency, route consistency, and optimality. To deal with the problem, a motion dynamics RRT * algorithm is proposed. Firstly, the characteristic of ellipses is utilized to effectively reduce the planning space in order to improve search efficiency;Next, in order to reduce the randomness of the RRT algorithm, a motion dynamics model of the aircraft is established and the state transition mode of nodes based on this model is designed;Finally, a cost function was designed to penalize the detour distance, climb altitude, and unsafe flight path. The experimental results on real DEM data show that the proposed algorithm can simultaneously meet the requirements of high efficiency, route consistency, and optimality for long-distance TF/TA route planning of large and medium-sized fixed wing aircraft. © 2023 IEEE.

In the design of nuclear magnetic resonance gyroscopes, the closed-loop control of the excitation magnetic field is crucial. Among various control methods, the phase-locked loop (PLL) is widely used to enhance the dynamic characteristics and stability of the gyroscope. This research employs the Second-Order Generalized Integrator (SOGI) as the phase detector, with the loop filter utilizing PI control. However, the system, being of type 2, cannot track acceleration signals without a static error. To address this limitation, we propose a loop filter design based on an Extended State Observer (ESO) integrated with PI control, effectively transforming the system into ESOPI-PLL, which is a type of Type3-PLL. Compared to the traditional SOGI-PLL system, simulation results demonstrate that our proposed scheme extends the gyroscope range to 2000 °/s, with a bandwidth of 30Hz, and achieves zero static error tracking. This advancement presents significant application potential for nuclear magnetic resonance gyroscopes. © 2024 IEEE.

The complex permeability of magnetic cores acts as a vital factor in electromagnetic interference (EMI) filtering choke design and optimization. Many efforts have been reported for toroid cores, but fewer target those with other shapes, such as EE, EI, UU, and UI cores. Owing to their commonly used in planar EMI filters, determining the complex permeability of them is of significance. Targeting EE cores, this paper presents a flexible printed circuit board (PCB)-based fixture adapter tailored designed for performing the measurement, while the corresponding core permeability can be calculated through magnetic flux path length analysis. The experiments validate the effectiveness and accuracy of the proposed methods, spanning a wide frequency range up to 120 MHz. ©2024 IEEE.

This paper introduces an innovative approach for the description and mapping of applications in the smart grid domain. By utilizing a skill-based engineering approach, not only flexibility and changeability will increase, but also the need for describing the same application multiple times for different grids decays. As a first use-case, Fault Location, Isolation, and Service Restauration (FLISR) as an example application and a real-world grid in Vietnam have been chosen. By showing how this novel approach could be applied to these two entities, its potential is demonstrated. The IEC 61850-based approach uses a two-step procedure for the mapping. After defining the application's requirements, a mapping algorithm can check if the application can be deployed to a specific grid. In the second step, the actual mapping is described to deploy the application to the devices in the field automatically. Having the requirement description, a recommender system can suggest possible adaptions to the grid in case the check fails.

In this article, we propose an updated version of our previously developed model for predicting drug-side effect associations, applied to two case studies: long QT syndrome and asthma. The classifier accepts the name of a specific drug side effect as input and outputs a list of drugs potentially associated with this side effect. By simulating how drug effects propagate within the interactome using the Random Walk with Restart algorithm, the classifier identifies genes potentially associated with the onset of the side effect. Based on the rationale that the more a drug perturbs these genes, the more likely it is to cause the side effect, the model identifies drugs potentially linked to the onset of the side effect. Moreover, the model enables the categorization of drugs into chemical subclasses using the ClassyFire schema, facilitating the analysis of complex side effects, such as asthma, through more specific mechanisms. The results show that the model identifies both drugs known to be associated with certain side effects, as well as drugs not officially reported by the FDA, demonstrating its generalizability and practical relevance. This method is also adaptable for analyzing other side effects. © 2024 IEEE.

The battery management system ensures the safe operation of electric vehicles (EVs) by detecting abnormalities in the battery energy storage system. However, the extensive and widely dispersed data in EV battery data, along with the presence of users’ private details, raise a demand for effective anomaly detection and privacy protection. To tackle those two challenges, we propose Fed-Autoformer, a distributed anomaly detection architecture based on real vehicle charging data to detect battery anomalies and protect privacy. Thus, we first propose a novel anomaly detection model for EV charging data based on the Autoformer encoder architecture. In particular, it enables an autocorrelation attention mechanism to extract and consider the intrinsic correlation of battery data features (e.g., voltage, current, state of charge (SOC), etc.) for anomaly detection. In addition, we introduce a federated learning architecture to protect the privacy of battery charging data and improve the federated learning training process based on the differences between vehicle batteries in charging stations to ensure detection accuracy while protecting the privacy of EV charging data. Finally, we comprehensively analyze the feasibility and effectiveness of our proposed architecture using a real EV charging dataset. Our proposed federated learning approach for EV battery anomaly detection not only effectively protects privacy through federated learning but also improves the accuracy by 3.2% compared to most mainstream time series anomaly detection models. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.
