Wang, S. (author), Zhu, Xiaoning (author), Shang, Pan (author), Lin, X. (author), Yang, Liya (author), Tavasszy, Lorant (author)The considerable increase in parcel deliveries has negatively impacted the accessibility and livability of cities. One solution strategy is to decouple short-distance from long-distance shipping so that last-mile transport can be performed with low-footprint vehicles. Such solutions are referred to in the literature as multi-echelon...journal article 2024

Zhu, R. (author), Yang, M. (author), Wang, Q. (author)Federated Learning (FL) has emerged as a privacy-preserving paradigm for collaborative deep learning model training across distributed data silos. Despite its importance, FL faces challenges such as high latency and less effective global models. In this paper, we propose ShuffleFL, an innovative framework stemming from the hierarchical FL, which...journal article 2024

Plastic particles affect N2O release via altering core microbial metabolisms in constructed wetlandsYang, X. (author), Chen, Yi (author), Liu, Tao (author), Zhang, Lu (author), Wang, Hui (author), Chen, Mengli (author), He, Qiang (author), Liu, G. (author), Ju, Feng (author)Constructed wetlands (CWs) have been proven to effectively immobilize plastic particles. However, little is known about the differences in the impact of varying sized plastic particles on nitrous oxide (N<sub>2</sub>O) release, as well as the intervention mechanisms in CWs. Here, we built a lab-scale wetland model and introduced plastic...journal article 2024

Ricci, Federica (author), Yang, M. (author), Reniers, G.L.L.M.E. (author), Cozzani, Valerio (author)Emergency response is a procedural safety barrier of paramount importance for the mitigation of fire scenarios and the prevention of escalation. However, in Natech scenarios, emergency response may be affected by the natural event impacting the site. Indeed, when contrasting Natech accidents, emergency responders have to face both the natural...journal article 2024

Sun, Hao (author), Wang, Haiqing (author), Yang, M. (author), Reniers, G.L.L.M.E. (author)To maintain continuous production, chemical plant operators may ignore faults or handle faults online rather than shutting down process systems. However, interaction and interdependence links between components in a digitalized process system are substantial. Thus, faults will be propagated to downstream nodes, potentially leading to risk...journal article 2024

Ji, C. (author), Hu, Jiqiang (author), Alderliesten, R.C. (author), Yang, Jinchuan (author), Zhou, Zhengong (author), Sun, Yuguo (author), Wang, Bing (author)This paper aims to illustrate the effect of the impact damage on fatigue behavior of CF/PEEK-titanium hybrid laminates. To achieve this end, a fatigue life model was proposed to predict the S–N curves of the laminates at various initial impact energy levels and stress ratios based on the energy dissipation approach. The energy dissipation...journal article 2024

General Optimal Trajectory Planning: Enabling Autonomous Vehicles with the Principle of Least ActionHuang, H. (author), Liu, Yicong (author), Liu, Jinxin (author), Yang, Q. (author), Wang, Jianqiang (author), Abbink, David (author), Zgonnikov, A. (author)This study presents a general optimal trajectory planning (GOTP) framework for autonomous vehicles (AVs) that can effectively avoid obstacles and guide AVs to complete driving tasks safely and efficiently. Firstly, we employ the fifth-order Bezier curve to generate and smooth the reference path along the road centerline. Cartesian coordinates...journal article 2024

Sun, H. (author), Yang, M. (author), Wang, Haiqing (author)Chemical process systems are becoming more automated and complex, which leads to increased interaction and interdependence between the human and technical elements of process systems. This urges the need for updating the safety assessment method by treating “safety” as an emergent property of a system. Uncertainty comes together with...journal article 2024
