This paper proposes a new variable gain robust state observer for a class of uncertain nonlinear systems. The variable gain robust state observer proposed in this paper consists of fixed observer gain matrices and nonlinear modification functions which are determined by appropriate updating rules. It is shown that sufficient conditions for the existence of the proposed variable gain robust state observer can be reduced to solvability of Linear Matrix Inequalities (LMIs). Finally, we give a simple numerical example. © 2024 IEEE.

State of health (SOH) estimation is foundational for effective health prognosis and management of lithium-ion batteries. However, conventional data-driven approaches struggle to ensure robust generalisability when training data lacks sufficient SOH labels. In this work, we explore the potential utility of ageing information, gathered from routine operational data beyond the standard input collection region, as proxy labels (PLs) to establish nonlinear mappings between a short charging segment and SOH. To achieve this, we develop a multi-task learning (MTL) framework for battery health monitoring, which comprises two critical components: (1) a deep MTL model, and (2) a multivariate Gaussian process regression (GPR) model. The deep MTL model is designed with four distinct tasks, each with a specific goal to exploit data under different labelling conditions, facilitating the extraction of domain-invariant and target-specific features for PL estimation. Using the estimated PLs, the GPR model is employed to provide precise mappings to SOH. Validations are conducted on batteries with diverse chemistries and cycling temperatures, particularly under severe label scarcity below 5%. The results confirm the effectiveness of the proposed method, outperforming baseline methods and achieving a mean absolute error of less than 1.3% in all case studies. © 1986-2012 IEEE.

The health of the lungs is significant importance to human well-being. As a vital respiratory organ, lung diseases have a high incidence and mortality rate worldwide. Accurate segmentation of the lung airways, including the trachea and bronchi, is crucial for the diagnosis of lung diseases. The recent coronavirus has further shown the importance of accurately distinguishing the lung airways from the lung parenchyma to assist in diagnosis. Therefore, developing an automated segmentation method that can accurately segment the lung airways from lung CT images is essential. Despite extensive research in this field, challenges remain. The unique tree-like structure of the lung airways and the fine-grained details at the terminal bronchioles pose difficulties for achieving precise segmentation using existing methods. In this study, we propose a novel dual-encoder network for accurate lung airways segmentation. Our method can efficient capture the local and global features using the combination of Convolutional Neural Networks (CNNs) and Transformer network. We evaluate our method on a lung CT dataset provided by Shandong University and demonstrate its superiority over existing methods. © 2023 IEEE.

This paper proposes a non-iterative LMI-based design strategy for guaranteed cost static output feedback controllers for linear systems. The proposed design approach is based on the well-known necessary and sufficient condition for the existence of the static output feedback stabilizing control for linear systems. In this paper, for linear systems we show the non-iterative LMI-based design procedure for static output feedback controllers which minimize the upper bound of a given quadratic cost function, and the effectiveness of the proposed static output feedback controller with guaranteed cost is presented through a simple numerical example. © 2023 IEEE.

Clustering algorithms are crucial in uncovering hidden patterns and structures within datasets. Among the density-based clustering algorithms, DBSCAN (Density-Based Spatial Clustering of Applications with Noise) has gained considerable attention for its effectiveness in various applications. However, determining appropriate parameter values for this algorithm remains a challenging task. This paper presents a novel methodology for eps parameter estimation for an improved DBSCAN, namely SS-DBSCAN. The experimental results across nine datasets demonstrate the efficacy of our proposed method in accurately determining clusters with eps value from SS-DBSCAN algorithm. The clusters identified using estimated eps values by SS-DBSCAN align well with the inherent structure of the datasets, yielding better cluster results than the manually set parameters and other methods used for automatic estimations of the eps for DBSCAN. Our approach adapted well to the peculiarities of each dataset, whether dealing with different scales, dimensions, or densities;it proved the versatility and robustness across various datasets, thereby emphasizing its generalizability and potential for broader applications. © 2023 IEEE.

Energy-Free Sensing and Context Recognition Using Photovoltaic Cells

引用

IEEE Sensors Journal 2025年第9期25卷 15598-15611页

作者： Shintani, Kaede Rizk, Hamada Yamaguchi, Hirozumi Osaka University Graduate School of Information Science and Technology Department of Information Networking Suita565-0871 Japan Tanta University Tanta31733 Egypt RIKEN Center for Computational Science Kobe650-0047 Japan RIKEN Center for Computational Science Department of Computer and Control Engineering Kobe650-0047 Japan

The field of energy-free sensing and context recognition has recently gained significant attention as it allows operating systems without external power sources. Photovoltaic cells can convert light energy into electrical energy to power sensing devices, but their power may not be sufficient to ensure energy-free sensing due to the varying power needs of sensors and high computational demands. In this article, we propose the use of photovoltaic cells as a standalone sensor for the recognition of different contexts, including user identification, step counting, and location tracking. The system utilizes the photocurrent readings generated by the photovoltaic cells to capture the unique mobility patterns of different users. By analyzing these patterns, the system can accurately identify the user, count the number of steps taken, and track the user’s location. We propose a computationally efficient dynamic time warping (DTW) to match the variable length sequences of photocurrent readings to a database of known patterns and identify the closest subject and location matches. The system was rigorously evaluated in a realistic environment, and the results indicate that it can accurately estimate step count, identify subjects, and localize them with an accuracy of 88%, 90%, and 43 cm, respectively. This is achieved while the proposed system is nonintrusive and can operate without external power sources, making it a promising technology for energy-free sensing and context recognition. © 2001-2012 IEEE.

Collection Responsibility Choice for Competing E-Tailing Supply Chains With Consumer Returns

引用

IEEE Transactions on engineering Management 2024年 71卷 283-295页

For implementing consumer returns policy in e-tailing, to whom consumers should return their purchases is a crucial operations decision. We develop game models of competing e-tailing supply chains to study how price competition, channel structure of competitor, and consumer returns policy affect collection responsibility scenario. There are two collection responsibility scenarios: manufacturer collection and electronic retailer (e-tailer) collection. We find that in the common e-tailer setting, the channel collection efficiency and existence of the fixed cost are important for the manufacturer to decide whether to accept the e-tailer's transfer of collection responsibility;if manufacturer collection is optimal for a manufacturer, then it is a win-win scenario for both the manufacturer and the e-tailer, i.e., they are better off using manufacturer collection. If e-tailer collection has higher channel efficiency than manufacturer collection, then e-tailer collection is chosen;otherwise, in the presence of fixed cost, we show that 1) both manufacturers collect returned products if market scale is large, the e-tailer collects them if market scale is small;otherwise, different collection responsibility scenarios are used;2) price competition accounts for the coexistence of different scenarios and reduces the range of manufacturer collection;3) the channel structure of competitor can reverse the effect of price competition degree on collection responsibility;and 4) the manufacturer with higher restocking fee has a smaller incentive to collect returns products. © 1988-2012 IEEE.
