However, accelerometer readings from AAVs in flight encompass both gravitational and external accelerations (EAs). The presence of EAs impacts the accuracy of attitude estimation. To enhance AAVs attitude estimation accuracy, this article proposes a two-stage extended Kalman filter (EKF) that incorporates constraints from aerodynamic forces and gravitational acceleration. In the first stage, an EA model based on aerodynamic force constraints is developed to calculate the <italic>y</i>- and <italic>z</i>-axis components of gravitational acceleration. Since low-cost AAVs do not have thrust sensors installed, the second stage employs gravitational acceleration constraints to compute the <italic>x</i>-axis component of gravitational acceleration. After acquiring the gravitational acceleration, optimal attitude estimation can be performed. To validate the performance of the proposed algorithm, a fixed-wing AAV experimental platform was established and subjected to flight-testing. The results indicate that the proposed algorithm achieves greater estimation accuracy compared to alternative algorithms during extended flights and high-dynamic or large-maneuvering conditions.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 9","pages":"14860-14874"},"PeriodicalIF":4.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143900447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional maintenance methods, relying on periodic inspections and reactive maintenance, often result in delayed fault detection, which increases safety risks. In order to address this challenge, this study proposes an innovative intelligent fault diagnosis approach that significantly enhances early fault detection and predictive maintenance without requiring structural modifications to the valve. The main contributions of this work are: 1) the development of a novel time-frequency analysis-based feature extraction method for current and pressure signals, which improves fault signature reliability and distinguishes fault patterns more effectively; and 2) the application of long short-term memory (LSTM) networks optimized using an improved particle swarm optimization (IPSO) algorithm, achieving 100% diagnostic accuracy for both solenoid valve and mechanical faults. Experimental results demonstrate the superiority of the proposed approach, with field tests successfully detecting torque anomalies and identifying risks related to solenoid valve power-off logic. This approach provides a robust solution for transitioning from preventive to predictive maintenance, significantly improving operational safety and pipeline reliability.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 9","pages":"16124-16139"},"PeriodicalIF":4.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work aims to enhance the temperature measurement sensitivity of distributed cascaded fiber Fabry-Perot interferometers (FPIs) based on the optical carrier-based microwave interferometry (OCMI) by utilizing the virtual Vernier effect. Considering that the magnification factor of the virtual traditional Vernier effect is constrained by the frequency scanning range, a novel virtual enhanced harmonic Vernier effect is proposed, wherein the two virtual reference FPIs and the sensing FPI form Vernier effects with frequency shifts in opposite directions, thereby achieving an enhanced Vernier effect. By designing the length differences between the two reference FPIs and the sensing FPI, which are twice plus a small detuning, the harmonic Vernier effect is constructed. The virtual enhanced harmonic Vernier effect achieves a sensitivity of 3322.54 kHz/°C and a magnification factor of 130.43, surpassing the sensitivity of the traditional and same-order harmonic Vernier effects. Additionally, the virtual Vernier effect allows for arbitrary adjustments to the length of the reference FPI, demonstrating the applicability of the proposed Vernier effect in distributed sensors composed of cascaded FPIs.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 9","pages":"15761-15769"},"PeriodicalIF":4.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To tackle this problem, we study the multiautonomous aerial vehicle (AAV)-assisted WSN, where AAVs provide relay services for the remote control communication from the base station (BS) to SNs and the transmission of D2D pairs under the proposed time switching nonorthogonal multiple access (TS-NOMA) protocols. We formulate the total throughput maximization problem by jointly optimizing the relay selection, time allocation, and relay deployment, subject to the quality-of-service (QoS) constraint. As the relay selection and time allocation could hardly be solved separately due to the information causality between them, we divide the formulated problem into the relay selection and time allocation subproblem, and relay deployment subproblem, and solve it by solving the two subproblems alternately. For the first subproblem, we propose a stochastic learning-based relay selection and greedy time allocation (SRSGTA) algorithm with strong global search capability. For the second subproblem, we propose an improved whale optimization (IWO) algorithm with advantages in both convergence speed and global search capability.

This work assumes that there are <italic>N</i> subsystems, and the DoS attacker can only target <italic>M</i> out of <italic>N</i> communication channels due to energy constraints. The attacker’s goal is to determine the optimal strategy to degrade the performance of remote state estimation. Two attack scenarios are considered: a model-based scenario where the attacker has knowledge of the overall dynamics and parameters of the system and a model-free scenario where the attacker lacks access to the wireless channel model. The problem is formulated as a Markov decision process (MDP) with an infinite time horizon. In addition, the optimal attack strategies corresponding to different importance function forms under various scenarios are considered, and solutions for some specific cases are provided.

E-noses mimic the olfactory sense of mammals to detect odors. Sensor drift, which refers to the change in sensor outputs over time, poses a significant challenge to the reliability of E-noses. MDCN utilizes metric learning and few-shot learning (FSL) within a metric learning framework to enhance stability against drift. Its advantage lies in maintaining good classification performance even when there are few samples in the target domain or when new categories emerge in the target domain. We evaluated the performance of MDCN in scenarios of category symmetry (where the source and target domains share the same categories) and category asymmetry (where there are fewer categories in the source domain) on two datasets: the pure gas dataset and the mixed gas dataset. In category symmetry scenarios, MDCN outperformed traditional and advanced methods, demonstrating high accuracy with a minimal number of reference samples. In category asymmetry scenarios, it also showed strong generalization capabilities and high accuracy. Comprehensive ablation experiments were also conducted to prove the rationality of the model architecture and its nondependence on a large number of target domain samples.
