The liquid sloshing introduces time-varying parameters that challenge the design of anti-rollover controllers. In response to this, this paper proposes an event-triggered, tube-based model predictive anti-rollover control strategy for liquid tank trucks that accounts for time-varying parameters. Firstly, to capture the time-varying characteristics resulting from liquid sloshing, this paper establishes a linear parameter-varying model. After analyzing the influence of liquid sloshing and time-varying parameters on rollover, a time-varying rollover index of the liquid tank truck is obtained using a parameter-state joint estimator for estimating difficult-to-obtain states and time-varying parameters. Then, this paper proposes a tube-based model predictive anti-rollover control strategy, which enhances the robustness of the control strategy to time-varying parameters in liquid tank trucks by incorporating system time-varying parameters within the tube. Furthermore, due to the limited bandwidth of the chassis CAN communication, an event-triggered mechanism is introduced to reduce communication resource consumption. Finally, this paper developed a hardware-in-the-loop anti-rollover test platform to validate the proposed strategy. The test results demonstrate that, under the proposed control strategy, the rollover angle of the liquid tank truck decreased by 35 %, and the lateral acceleration was reduced by 50 %. Additionally, the communication resource occupancy decreased by 39 %. The proposed anti-rollover control strategy effectively reduces the rollover risk and enhances the driving safety of liquid tank trucks.</div></div>","PeriodicalId":50615,"journal":{"name":"Control Engineering Practice","volume":"164 ","pages":"Article 106499"},"PeriodicalIF":5.4,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144703672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing solutions focus on modeling item representations as fixed embedding vectors within the discriminative learning paradigm, which fail to accurately capture the diverse preferences that user exhibit during dynamic decision-making. We argue that users in the anonymous environment can fundamentally be regarded as a <strong>normative implicit group</strong>, exhibiting both <strong>homogeneous preference</strong> and <strong>heterogeneous preference</strong> when selecting items. To tackle this, we propose a Diffusion Model for Session-based Recommendation (DiffSBR). Specifically, we first model the aforementioned user diverse preferences from both local and global views. Next, we introduce a cluster-aware diffusion model, which directly represents heterogeneous preference clusters as distribution through forward and reverse processes, while indirectly influencing homogeneous preference via the attention mechanism in the final prediction stage, thereby improving the learning of item and session representations and enhancing the next-item recommendation. Experimental results show that DiffSBR outperforms the strong baseline, demonstrating that this sampling-allocation approach accurately reflects the uncertainty and variability in user preferences.</div></div>","PeriodicalId":50365,"journal":{"name":"Information Processing & Management","volume":"63 1","pages":"Article 104284"},"PeriodicalIF":7.4,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144703791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this paper is to design an efficient task offloading mechanism to maximize group efficiency in vehicle computing. Considering that sensing data inherently support multi-user sharing, we introduce a resource-sharing model in which multiple users share sensing resources. To provide a scalable service, we propose auction-based dynamic pricing. To achieve a balance between quality and efficiency, the efficient task offloading mechanism proposed in this study is based on dwarf mongoose optimization. The initialization algorithm generates random, best-fit, and greedy allocations based on probability. Convergence characteristics are improved using a new scouting algorithm and a new babysitter algorithm, both of which also contribute to maintaining population diversity. We demonstrate that the proposed mechanism achieves strategy-proofness, group strategy-proofness, individual rationality, budget balance, and consumer sovereignty. The novelty consists in our showing how to design the strategy-proof mechanism based on swarm optimization. Furthermore, the approximate ratio of the proposed mechanism is analyzed.
