Spatial community detection plays a crucial role in the analysis of spatially embedded networks. However, most existing methods adopt modularity as an objective function, which may fail to detect small spatial communities (i.e. well-known resolution-limit problem). To alleviate this problem, local network structure-based constrained Leiden method was developed. First, weights edges were reset based on structure, facilitated clearer delineation between distinct communities. Second, we extended Leiden, effective method, content by adding constraints. Experiments simulated datasets demonstrated that proposed is superior four state-of-the-art for detecting different sizes. A case study conducted using Shenzhen taxi dataset outperformed revealing urban structures. Notably, detected exhibited marked improvement, nearly doubling comparative study. This presents novel and promising framework modularity.

The global containerisation industry, while significantly advancing international trade, faces persistent challenges related to infrastructure capacity, environmental impact, and operational efficiency. One critical yet under-researched issue is the physical damage that containers endure during handling operations, particularly at port terminals. This paper examines complexities of container handling, focusing on caused by quay crane activities, especially corner hooking. Such compromises integrity, impacts cargo safety, increases costs. To address these concerns, we present Impact Detection Methodology (IDM), a system designed monitor detect in real time, enhancing precision safety. Preliminary studies conducted Klaipeda City demonstrate IDM's effectiveness, though limited data have constrained validation. Our research underscores need for broader experimentation confirm potential mitigating damage. Key findings indicate unsuccessful hooking attempts predominantly occur when are lifted from above-deck positions, influenced spreader oscillations high workloads. also highlights importance integrating sway control systems with existing management technologies assist operators reducing errors. Enhanced monitoring analysis essential improving processes, supporting sustainable growth containerisation, financial risks.
