The system's operation framework and design rules ensure effective implementation. To address ethical concerns in complex scenarios, IDES includes a reversion mechanism that switches dynamic signs back to conventional static signs when necessary. The system's effectiveness is demonstrated through prototyping in a lab-scale tunnel model, assessing both the dynamic patterns and hardware reliability.

However, compared with single-hazard, multiple disasters confront the challenges of complexity, diversity, and demand urgency. To improve the efficiency of emergency material distribution under multiple disasters, this study first divided multiple disasters into three categories: independent scenario, sequential scenario, and coupling scenario. A set of evaluation index systems for multiple disasters was established to quantify the urgency of demand. The routing optimization model of emergency vehicles for multiple disasters was proposed by combining demand urgency and road damage, and the non-dominated sorting genetic algorithm II (NSGA-II) was used to simulate and validate the model. A coupling scenario considering two typical disasters of hurricanes and epidemics was selected as a validation example, and sensitivity analysis was also performed for different algorithms, scenarios, and constraints. The results demonstrated that the proposed model could effectively address the vehicle routing problem of emergency materials in the context of multiple disasters. Compared to the NSGA, the NSGA-II was used to reduce the total delivery time, cost, and penalty cost by 15.98%, 13.60%, and 16.14%, respectively. Compared with the independent scenario, the coupling scenario increased the total delivery time and cost by 186.28% and 132.48% during the epidemic. However, it reduced the total delivery time by 4.00% and increased the delivery cost by 23.55% compared with the hurricane. Compared with the model without consideration, the model considering demand urgency and road damage reduced the total delivery time and cost by 17.88% and 8.73%, respectively. The model constructed in this study addressed the vehicle routing problem considering the demand urgency and road damage in the optimization process, particularly in the context of multiple disasters.</div></div>","PeriodicalId":62710,"journal":{"name":"安全科学与韧性(英文)","volume":"6 2","pages":"Pages 196-211"},"PeriodicalIF":3.7,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143829389","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}

To achieve this objective, two key objectives have been identified: (1) reducing unserved loads, and (2) implementing cost-effective resource allocation strategies.

This model is based on the conceptual design of a campus microgrid facility, which is slated for commissioning at UL Lafayette in close collaboration with a local power utility. The study examines the microgrid’s performance under different configurations, including both stationary battery and mobile battery storage options. To ensure the realism of the scenarios, real solar data from specific days following the occurrence of three major hurricanes in Louisiana is utilized. The analysis includes an assessment of unserved loads under various scenarios, as well as an investigation into the resilience impact of investment decisions and the planning and operation of mobile storage systems. The results indicate the proposed planning and operation will improve resilience while staying within the profitable range. The resilience is quantified and compared with other scenarios providing an insightful planning framework for decision-makers.</div></div>","PeriodicalId":62710,"journal":{"name":"安全科学与韧性(英文)","volume":"6 2","pages":"Pages 163-174"},"PeriodicalIF":3.7,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143792727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fire evacuation scenarios for children's cultural centers, it is necessary to create appropriate evacuation conditions. In this work, fire safety was analyzed over total evacuation time within occupant-based fire evacuation simulations of a children's cultural center located in Istanbul. The effect of the children's theatre hall located on the top floor on a building's total evacuation time has been studied. The effectiveness of alternative fire escape routes on evacuation time through different evacuation scenarios has been analyzed, and safe evacuation strategies for children's cultural centers have been revealed. As a result of this study, recommendations were presented within performance-based fire evacuation strategies in the design of children's cultural centers.

The VSL measures the monetary value the public assigns to reducing mortality due to a specific risk (e.g., dying from an earthquake) over a given period. In the absence of appropriate models to estimate the context-specific VSL for a given community, past studies have resorted to approaches such as using the VSL estimated for other purposes (e.g., transportation and environmental safety) or other countries (e.g., the US). This can lead to under- or over-estimation of VSL, misappropriation of the funds for seismic vulnerability reduction programs, and adverse economic, political, and social consequences. This study proposes a methodology that follows the stated preference binary choice approach to estimate the willingness to pay (WTP) to reduce the risk of earthquake-induced mortalities. The proposed method, which is applied to quantify VSL in Iran, involves using a questionnaire to collect the needed information about people's choices when investing in various risk reduction measures. It uses a test containing positivity and proportionality components to check the responses’ consistency.

Increasing payload capacity often reduces stego image quality and security. However, maintaining high-quality stego audio with high imperceptibility requires compromising payload capacity. Therefore, achieving a balanced trade-off between payload capacity and stego audio quality has become essential but increasingly challenging. Current methods often lack adaptiveness, potentially compromising both embedding capacity and stego audio quality. To address these limitations, this study offers valuable insights to guide researchers in developing high-performing audio steganography models. The proposed method seeks to improve stego audio quality by implementing a smoothing-based technique and optimizing the sample space through linear interpolation, followed by a multi-layering process. Comprehensive experiments are conducted on common audio datasets to benchmark the method against state-of-the-art techniques. The results demonstrate peak signal-to-noise ratio (PSNR) values ranging from 105.14 to 126.34 dB, indicating substantial fidelity preservation compared to existing methods with PSNR values ranging from 120.55 decibel (dB) for 1 kb to 100.57 dB for 100 kb. These findings confirm the effectiveness of the model in maintaining audio quality while concealing data.
