Vehicle-to-everything (V2X) perception is an innovative technology that enhances vehicle perception accuracy, thereby elevating the security and reliability of autonomous systems. However, existing V2X perception methods exhibit limitations at traffic intersections due to a failure to account for effective collaboration between dynamic vehicles and stable Roadside Unit (RSU) in adapting to traffic environments. To harness the use of RSU and adapt V2X perception models to dynamic scenes, we propose an Adaptive Road-to-Vehicle Perception (AR2VP) approach, building V2X perception based on road-to-vehicle visual information. In AR2VP, we leverage RSU to offer stable, wide-range sensing capabilities and serve as communication hubs. AR2VP is devised to tackle both intra-scene and inter-scene changes. For the intra-scene changes, we construct a Dynamic Perception Representation (DPR) module, which effectively integrates vehicle perceptions, enabling vehicles to capture a more comprehensive range of dynamic factors within the scene. Moreover, we introduce a Road-to-Vehicle Perception Compensating (R2VPC) module, aiming at preserving the maximized RSU perception information in the presence of intra-scene changes. For the inter-scene changes, we implement a Prompt-Replay mechanism leveraging the RSU's limited storage capacity to retain a subset of typical historical scene samples, maintaining model robustness in response to inter-scene changes. We conduct comprehensive experiments on 3D object detection and segmentation, and the results show that AR2VP excels in both performance-bandwidth trade-offs and adaptability within dynamic environments.

Considering the directional characteristics of communication topology due to heterogeneity in distance, power, and so on, a fully distributed consensus-based low-carbon economic dispatch method with directed topology is investigated in this paper. First, a low-carbon economic dispatching model is established with the consideration of dual goals of maximizing economic benefits and reducing carbon emissions, which employs quadratic functions to calculate operation and maintenance costs of subsystems along with carbon trading costs and introduces the Lagrange multiplier method to solve the optimization problem. Second, a fully distributed dispatching algorithm is proposed for large-scale and complex power networks. Our proposed algorithm treats incremental costs as consensus variables based on consensus theory, which realizes distributed dispatching through iterative computation. Third, the algorithm's applicability under random directed communication topology is thoroughly investigated. With the introduction of a surplus variable, the effectiveness and convergence of the algorithm have been confirmed through the analysis of communication topology and adjacency weights. Finally, some numerical experiments under the IEEE-14 power system are carried out to show the effectiveness of our proposed method. © 2024 Technical Committee on Control Theory, Chinese Association of Automation.

Multi-label class-incremental learning (MLCIL) is essential for real-world multi-label applications, allowing models to learn new labels while retaining previously learned knowledge continuously. However, recent MLCIL approaches can only achieve suboptimal performance due to the oversight of the positive-negative imbalance problem, which manifests at both the label and loss levels because of the task-level partial label issue. The imbalance at the label level arises from the substantial absence of negative labels, while the imbalance at the loss level stems from the asymmetric contributions of the positive and negative loss parts to the optimization. To address the issue above, we propose a Rebalance framework for both the Loss and Label levels (RebLL), which integrates two key modules: asymmetric knowledge distillation (AKD) and online relabeling (OR). AKD is proposed to rebalance at the loss level by emphasizing the negative label learning in classification loss and down-weighting the contribution of overconfident predictions in distillation loss. OR is designed for label rebalance, which restores the original class distribution in memory by online relabeling the missing classes. Our comprehensive experiments on the PASCAL VOC and MS-COCO datasets demonstrate that this rebalancing strategy significantly improves performance, achieving new state-of-the-art results even with a vanilla CNN backbone.

Global warming is a serious threat common to all countries. The technological revolution and sustainable development of energy have become the international consensus. While ensuring economic benefits, promoting low carbon environmental protection of comprehensive energy system has become a top priority. Therefore, this paper designs a low-carbon economic scheduling system based on consistency theory. First, the importance of user demand response should be considered in the integrated energy system to ensure the economy of scheduling. Secondly, the improved step-step carbon trading mechanism is used in the algorithm to improve the low carbon performance of scheduling. Then, the distributed consistency algorithm is used to schedule the integrated energy system to realize the most energy output of each unit. In addition, a noise function is added to the algorithm for encryption and desensitization to prevent user privacy leakage. Finally, the effectiveness of the proposed economic scheduling method. © 2024 Institute of Physics Publishing. All rights reserved.

Aimed at the existing problems, such as the improving requirements on privacy, and the low quality of collected data in mobile crowd sensing, one online Quality-based Privacy-preserving Task Allocation (QPTA) mechanism is considered in this paper. First, a travel budget-related polynomial is designed to measure the influence of candidate tasks on the whole task quality, and an online task quality-based allocation model is designed to maximize the total task quality when both the budget and time constraints can be satisfied simultaneously. Second, when the perceived data of task participants and requesters are encrypted values, with the introduction of typical Paillier homomorphic encryption technology, the division, the square root, and the Euclidean distance calculations of the encrypted values are then designed. In this way, the encrypt calculations of the task allocation algorithm are solved, and the data privacy of the task allocation system is thus preserved. Then, the bilateral privacy analysis of the proposed method is illustrated, and some simulations are carried out to show the effectiveness of the proposed method. Simulation results show that the proposed method can allocate tasks effectively while guaranteeing the privacies of both the participants and requesters. It outperforms the most related methods in terms of average perceived quality. © 2024, The Authors. All rights reserved.

Building shadow ratio is an essential indicator in the design of the thermal environment of residential areas in hot and humid regions, and a reasonable quantification of building shadows can accurately assess the shading status of the residential areas. The study analysed the relationship between building shadow ratio (gBSR), sky view factor (SVF), temperature (ground surface, air, and mean radiant temperatures), and thermal comfort index (UTCI). The results show that (1) there is a strong negative correlation between gBSR and SVF;(2) there is also a strong correlation between gBSR, SVF, and temperature and thermal comfort, but gBSR is stronger explanatory for UTCI than SVF;and (3) as SVF increases, or gBSR decreases, AT rises almost throughout the daytime, whereas GST, mRT, and UTCI are all on the rise during the daytime and then will gradually decrease. The study provides new methods for optimising the thermal environment of settlements from the perspective of building shadow. © ASCE.
