The compressed-air foam spray nozzle is a novel end-release device that, due to its high efficiency and excellent suppression effect on oil-based fires, has been increasingly applied in UHV substations. This study is based on a self-developed experimental platform for compressed-air foam firefighting systems. To meet practical engineering needs, the longitudinal maximum of the contour line at the threshold of 12 L/(min·m²) was selected as the spray range. The study systematically explored the factors influencing the spray range of the spray nozzle. Experimental results revealed that when the hole elevation angle was 60°, the average spray range increased by 59 % compared to 0°. When the nozzle aperture was 10 mm and the outlet pressure was 0.15 MPa, the spray range improved by 17 %. Additionally, as the outlet pressure increased, the foam spray range grew significantly, with a 35.2 % increase at 0.3 MPa compared to 0.1 MPa, indicating that the outlet pressure had a substantial effect on the spray range. To predict the spray range increase, an empirical model is developed for the outlet pressure versus the spray range. After analyzing the above three influencing factors, all the data of various working conditions were integrated into a single dataset, a prediction model of the spray range was established, and the importance of the factors affecting the range was ranked.

The model yields an 86.3 % accuracy in predicting outcomes for the two extreme levels of corruption risk. The findings indicate that the “high risk” state of corruption can significantly hinder progress on the “good health and well-being,” “zero hunger”, and “peace, justice and strong institutions” SDGs. Conversely, the “low risk” state of corruption can significantly enhance performance on the “sustainable cities and communities”, “zero hunger”, and “no poverty” SDGs.

This study presents a comprehensive comparative analysis of the bibliometric patterns and methodological trends in flood mitigation research over the past two decades, identifies prevailing gaps, and proposes future research directions to enhance the effectiveness of flood mitigation strategies. Using data from the Scopus database, 441 publications were objectively selected and subjected to metadata analysis. The study identifies top authors, contributing institutions, nations, and the distribution of contributions across different fields and methodologies. The findings emphasize the need for an integrated and interdisciplinary approach to flood reduction research, considering the complex interplay of social, ecological, and physical dimensions in flood risk management. The study reveals the predominance of modeling and simulation approaches, geographic information systems (GIS) remote sensing approaches, and statistical and data-driven approaches as the most widely employed methodologies. Furthermore, it highlights the growing diversity of approaches, with increasing interest in machine learning algorithms and combined methods. Also, this study provides valuable recommendations for future research, emphasizing the importance of developing effective flood-mitigating strategies to enhance community resilience. It advocates for a multidisciplinary and integrated approach, leveraging geospatial technologies, machine learning algorithms, and collaborative methodologies to advance flood mitigation research and practice. Future research should consider exploring additional databases, including Web of Science, EBSCO, IEEE, and Google Scholar, to conduct a more comprehensive review of the available literature.

With advancements in technology and growing societal needs, modern airports are evolving toward smarter and more integrated systems. While transportation engineers and planners aim to bolster resilience in subsystems and transport management with new technologies and diverse strategies for effective risk management, the growing complexity of disaster-inducing factors and fire dynamics in airport systems somewhat diminishes the accuracy of existing risk vulnerability analyses. It drives the demand for enhanced firefighting resilience. This study discusses assessment and improvement strategies for enhancing the resilience of airport firefighting systems in the context of smart airports. Specifically, we analyze the resilience characteristics of airport firefighting systems, which can be subdivided into four dimensions: stability capability, resistance capability, recovery capability, and adaptability capability. Furthermore, by integrating human, mechanical, environmental, and managerial elements, a comprehensive resilience evaluation indicator system is constructed. We propose a modified composite weight calculation framework that innovatively introduces genetic algorithm (GA) in the weight combination process to simplify the model into a constrained minimization problem from a mathematical perspective, thus making the ranking results reflect ordinal and intensity information. The findings highlight the significance of technological advancements, emergency response capabilities, expertise in fire management, cross-departmental collaborative responses, personnel psychological quality, and accident investigation skills in enhancing the resilience of airport firefighting systems. Although the comprehensive evaluation model based on expert knowledge still focuses primarily on resistance, the criterion of adaptation capability has a more pronounced increasing trend in weight under correction, highlighting its significant role and potential in future airport firefighting resilience indicators.

While many effective spatiotemporal crime prediction methods have been proposed, most overlook this issue, reducing their ability to generalize. In this paper, we introduce a novel deep learning-based model, adaptive-GCNLSTM (Ada-GCNLSTM). Specifically, in the spatial feature extraction module, we enhance the model's ability to capture crime spatial distributions by leveraging graph convolutional networks to model spatial dependencies in conjunction with the maximum mean discrepancy to extract the universal features of crime data. We then incorporate a memory network based on long short-term memory network to capture the underlying relationships between temporal features.

The goal of this research was to systematically characterize the vulnerability of industrial critical infrastructures (ICIs) to various hazards in their territories. A multi-scale procedure was implemented in the Italian context as a case study, where spatial analyses were developed using open data. Starting from the Italian national inventory, the MHIs were clustered in industrial macro-sectors and represented nationally by regions, relating their distribution to meteorological or geophysical data of interest. At the regional scale, the MHIs of the Piedmont Region were represented as punctual elements, associating the population within potential damage zones by province. At the municipal scale, a previously validated multi-hazard tool for vulnerability assessment was then tailored to a reduced scale for specific applications in an industrial context. This adaptation, which considers the two-way interaction between an energetic critical infrastructure and various hazards in its surroundings, delivers a spatial vulnerability profile that may complement the probabilistic analysis of industrial incidental scenarios. In summary, this framework may raise the stakeholders awareness at various levels and with different interests within the industrial accident control decision-making chain, from operators to competent authorities.</div></div>","PeriodicalId":62710,"journal":{"name":"安全科学与韧性(英文)","volume":"6 2","pages":"Pages 297-315"},"PeriodicalIF":3.7,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
