With the widespread deployment of location-aware mobile devices, a mass of trajectory data is being generated and collected. Mining co-movement patterns of people and vehicles from streaming and massive trajectory data has attracted much attention due to its wide applications in various fields. As a typical co-movement pattern, convoys describe objects moving together in consecutive timestamps. There are two challenges for efficient distributed convoy mining: object clustering and workload balancing. Clustering objects in each time snapshot is a time-consuming operation. In addition, on the basis of practical application scenarios, load balancing is an important consideration for distributed algorithms. To tackle the above challenges, we propose a novel method for distributed convoy mining via sliding window-based indexing and sub-track partitioning, abbreviated SWISP. We offer three major advancements. First, we develop a grid-based DBSCAN clustering algorithm named Grid-DBSCAN for distributed scenarios. It avoids the exhaustive calculation of pairwise distances for neighborhood search and thus improves computational efficiency in the clustering stage. Second, we propose a sliding window-based indexing scheme to filter out sub-tracks with less than $k$ consecutive time snapshots, significantly reducing the number of candidate sub-tracks for convoy mining. Third, we develop a distributed convoy mining algorithm based on sub-track partitioning. It exploits both temporal and spatial information of sub-tracks for data partitioning and solves the data skewness problem caused by uneven data distributions. We conduct extensive experiments on four real-world datasets. The experimental results show that our distributed algorithm can handle large-scale trajectory data and is more efficient than state-of-the-art approaches.

In distributed state estimation for linear systems with multi-sensor networks, the event-triggered fast information consensus filtering algorithm (ET-FICF) is proposed to address the problems of high communication burden and high number of iterations of the information consensus algorithm. The algorithm utilises a distributed fast consensus weighting algorithm based on alternating direction multiplier method (ADMM) to obtain the weight matrix. For the consensus iteration step, a specific trigger mechanism is designed based on hypothesis testing of Gaussian distribution. The proposed ET-FICF algorithm not only effectively reduces the communication burden, but also has a high consensus speed. Finally, the correctness and effectiveness of the proposed algorithm are verified by simulation examples.

This paper introduces an improved Canny edge detection algorithm. The algorithm replaces traditional Gaussian filtering with bilateral filtering, which better preserves edge structures and ensures more precise edge detection in detailed regions. Additionally, the algorithm employs adaptive histogram equalization to enhance the local contrast of the image. At the same time, the adaptive thresholding in the algorithm enhances the detection performance for edges of varying intensities, such as weak and strong edges, particularly in low-contrast areas. During non-maximum suppression, a neighborhood comparison of edge pixels is manually implemented based on gradient direction to ensure that only local maximum edges are retained, increasing the precision in processing gradient directions, particularly for slanted or subtle edges. Finally, the algorithm applies morphological techniques to refine edges. Experimental findings show that the enhanced algorithm boosts the accuracy of object edge detection from 0.717 to 0.750.

In this paper, we propose a practical integrated sensing and communications (ISAC) framework to sense dynamic targets from clutter environment while ensuring users communications quality. We design multiple communications beams that can communicate with users while one rotating sensing beam can scan entire space, and then we propose the supporting beam-forming design and power allocation strategies for such design. Unlike most existing ISAC studies that ignore the interference of static environmental clutter on target sensing, we construct a mixed sensing channel that includes both static environment and dynamic targets. When base station receives echo signals, we first provide a practical clutter filtering method to filter out static environmental clutter. Then dynamic target detection and angle estimation are realized through angle-Doppler spectrum estimation (ADSE) and joint detection over multiple subcarriers (MSJD), while distance and velocity estimation are realized through the extended subspace algorithm. Simulation results are provided to demonstrate the effectiveness of the proposed scheme.

The compensation of inverter nonlinearity is of great significance for improving the control performance of permanent magnet synchronous motor drive systems. In this article, an online inverter nonlinearity compensation method based on the adaptive gain second order generalized integral is proposed for obtaining dq-axis current harmonics caused by inverter nonlinearity. Therefore, the complex offline test of the inverter nonlinearity can be avoided. In addition, considering the phase shift of the second order generalized integral filter and the time delay caused by controllers, a suppression strategy based on self-adjustment a bandwidth method is proposed. Finally, the method is verified on an 11.7kW permanent magnet motor test platform.

Lithium-ion (Li-ion) batteries have gained significant attention in applications such as electric vehicles and hybrid vehicles and vessels. An important variable of the battery pack is the state-of-charge (SoC), which is not deterministic and cannot be measured accurately using the currently available methods, but it requires estimation. The Kalman filter algorithm has proven to be reliable in estimating the charging level of Li-ion batteries. In this paper, we compare the performance of two different Kalman-based algorithms in terms of robustness and accuracy, also distinct in the nonlinearity scheme. A polynomial curve fitting method is customized to estimate the essential Li-ion battery parameters based on its Thevenin equivalent circuit model. Then, the output of these parameter estimations is propagated through two Kalman filters: extended Kalman filter (EKF) and the unscented Kalman filter (UKF). The implemented filter algorithms are validated using realistic data collected from a functional hybrid vessel operating between the Nordic countries. Further validation for the battery parameters is done using laboratory experiments on battery packs. The SoC estimation results show that both filters EKF and UKF converge robustly and reliably. However, UKF is further recommended as it outperforms EKF in terms of battery SoC estimation accuracy with an advantage of 0.05% error, hence, making UKF more suitable for real-time Li-ion battery-based applications.

Attaining high angular resolutions through compact designs is a preferred approach for vehicles with increasingly dense packaging, aiming to achieve higher levels of automation. Hence, the motion of the MIMO radar platform has been exploited to obtain higher cross-range resolution in off-boresight through forward-looking (FL) MIMO-SAR, but no improvements have been made in boresight which is the most crucial direction for path planning. In this paper, we propose use of Burg algorithm (BA) with FL MIMO-SAR technique to enhance the cross-range resolution in boresight and to achieve further enhanced the resolution off-boresight. Here backprojection (BP) is used to obtain SAR images. BA is applied either before or after BP image formation and the performance of both methods is compared based on the analysis of achieved resolution, background level and computational resources required. The proposed methods are validated through both simulation and real-world experiment conducted at 77 GHz.

Dynamic ridesharing has garnered significant attention in recent years due to its numerous benefits. Existing ridesharing algorithms often employ a “filter-and-refine” frame-work, where a large set of candidate vehicles is initially selected for each ride order, followed by computationally intensive route planning for each candidate. However, this process can lead to significant response delays and limit system efficiency. To address this challenge, we propose an order-vehicle pre-matching recommendation approach (PreMR) that refines the candidate set before route planning. PreMR leverages spatial-temporal intervals and a self-attention mechanism to encode diverse order and vehicle information into uniform and informative representations, enabling it to accurately identify the most suitable vehicles for each order. Extensive experiments using real-world datasets and four representative ridesharing algorithms demonstrate that PreMR significantly reduces order response time (by 46.78% on average) while maintaining high service quality, with a slight trade-off in the order completion rate.

In order to solve the problems such as low efficiency of cloud manufacturing resource allocation and unreasonable selection of manufacturing services, this project intends to study the resource-oriented cloud manufacturing resource allocation strategy based on user demand. By introducing the methods of data warehouse, online analysis and processing, and data mining, the functional model of ERP data analysis is established. The dual-track mechanism of case base and model base is applied to the process design of model intelligent decision support system (IDSS) and the corresponding algorithm is proposed. A multi-index optimization modeling method for cloud manufacturing based on time-expense-quality-of-service and customer satisfaction was constructed. In this project, Chebyshev filter is combined with second-order vibration to solve the problem of early convergence of particle swarm. The variation factor is added to the subjective weight to reflect the contrast strength of the target data. The numerical simulation shows that the new algorithm has a wide range of solutions and good convergence performance, and also proves the correctness of the proposed theory and decision method.

As power electronics move to high switching frequency, electromagnetic interference (EMI) is receiving increasing attention. The application of digital active EMI filters (DAEF) effectively reduces the size of passive filters and improves the applicability of AEF. However, the characteristics of noise sources change with the changing working conditions, which requires greater adaptability. Therefore, this paper designs an adaptive DAEF based on the LMS algorithm. A delay compensation algorithm is also proposed to address the delay issue introduced by the system's secondary path.
