These systems can provide personalized support by continuously assessing the user’s state and optimizing intervention strategies. Physiological data acquisition through advanced sensors enables objective and real-time workload estimation, offering a more reliable alternative to self-reported measures. Despite the growing interest in workload estimation, existing literature reviews are often domain-specific or focus on cognitive workload only, without providing a comprehensive analysis of methodologies for estimating both physical and cognitive workload across different applications. To address this gap, this systematic review analyzes 35 studies on multimodal physiological monitoring, examining feature extraction methodologies and supervised learning models used for workload estimation. The review identifies key challenges, including the need for standardized protocols, improved generalization across real-world scenarios, and the integration of adaptive artificial intelligence models. It underscores the role of sensor-based workload estimation in healthcare, rehabilitation, and assistive technologies, positioning it as a fundamental component for developing intelligent, user-centered, and adaptive human–machine interaction systems.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 18","pages":"34298-34310"},"PeriodicalIF":4.3,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11126940","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To mitigate this issue, a study has been conducted to explore the factors influencing armature levitation force in the EICL. This scholarly work presents a mathematical model of levitation force, developed using current filament methods, and substantiates its accuracy through rigorous validation. A methodology has been proposed to assess the levitation force of the armature in EICL, focusing on two key aspects: the peak value of the levitation force and the time required to achieve this peak. By altering one or multiple system parameters of the EICL, an analysis of the levitation force variation patterns has been performed. A comprehensive synthesis has been conducted to elucidate the impact of systemic parameter variations on the armature levitation force in electromagnetic induction coil systems. The application of dynamic and electromagnetic coupling levitation simulation has been extended to the EICL, offering guidance for subsequent design principles related to emission control, as well as armature and tube structures.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 9","pages":"2428-2439"},"PeriodicalIF":1.5,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145061843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The time-varying characteristics of spark resistance significantly impact voltage rise time and energy transfer efficiency. However, accurately measuring spark resistance in underdamped discharge circuits is challenged by current oscillations. To address this, this article proposes a Simulink-based method for reconstructing experimentally measured spark currents to calculate spark resistance. An improved computational model is established by incorporating a spark resistance recovery function term into the Rompe–Weizel (R–W) resistance formula. The model’s accuracy is validated through spark discharge experiments with a 2-mm electrode gap. Furthermore, the influence of discharge voltage and gap length on the temporal evolution of spark resistance is analyzed. Results demonstrate that spark resistance rapidly decreases from a high-impedance state (<inline-formula> <tex-math>$1times 10^{5}~Omega $ </tex-math></inline-formula>) to a low-impedance state (<inline-formula> <tex-math>$lt 1~Omega $ </tex-math></inline-formula>) within tens of nanoseconds after discharge initiation, followed by a gradual recovery until the gap regains its insulating properties. Quantitative analysis reveals spark resistance is inversely proportional to the discharge voltage and directly proportional to the electrode gap distance.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 9","pages":"2284-2291"},"PeriodicalIF":1.5,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in complex environments such as urban canyons and tunnels, the global positioning system (GPS) signals are often blocked or interrupted, resulting in decreased or invalid positioning accuracy. To meet the demand for accurate vehicle positioning in complex environments of urban roads, this article proposes a deep learning model for GPS pseudo-range and Doppler shift prediction based on the fusion of the animated oat optimization (AOO), a convolutional neural network (CNN), a bidirectional gated recurrent unit (BiGRU), and an attention mechanism. CNN is applied to capture spatiotemporal features from the input sequence, while BiGRU explores the long-term dependencies in the data. The attention assigns varying weights according to the importance of input data, enabling the model to focus more effectively on critical parts. To improve predictive accuracy, the AOO algorithm is employed for hyperparameter optimization. Then, the predicted GPS pseudo-range and Doppler shift are used for GPS/ultrawide band (UWB) tightly coupled cooperative positioning by utilizing the characteristics of UWB technology that can provide high-precision ranging information. The results of the experiment show that the proposed fusion model improves the relative positioning accuracy by 13%, 29%, 33%, and 50% over CNN-BiGRU-Attention, CNN-BiGRU, BiGRU, and GRU models, respectively, during a GPS signal loss-of-lock environment, which significantly enhances the stability of vehicle positioning in complex environments.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 18","pages":"35312-35322"},"PeriodicalIF":4.3,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073166","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}

In this work, the effects of electron irradiation and thermal cycles on SiC MOSFET devices were studied. The experimental and simulation results show that the electron irradiation makes oxide capture a large number of positive charges, which leads to the negative drift of threshold voltage. When the irradiation dose is 1Mrad, the threshold voltage is reduced by 17%. The thermal cycling induced stress concentration at the SiC/SiO2 interface results in lattice dislocation and mismatch at the interface, which increases the amount of charge. After 120 cycles, the threshold voltage of the devices is reduced by 32.75%. On this basis, the same device was subjected to electron irradiation and thermal cycling in turn. The experimental results show that thermal cycling can further aggravate the threshold voltage drift induced by electron irradiation.","PeriodicalId":448,"journal":{"name":"IEEE Transactions on Device and Materials Reliability","volume":"25 3","pages":"684-691"},"PeriodicalIF":2.3,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145027942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
