By the early 7th century BC, Megara had likely reached its maximum intramural size of approximately 60 hectares. This study focuses on that formative phase to evaluate whether the community possessed the resources to undertake two key construction projects: the first city fortification and residential expansion. <b>Methods:</b> Archaeological evidence shows that residential structures spread across the Southern Plateau and toward the Archaic West Gate by the early 7th century BC. This urban spread correlates with the construction of the city's earliest defensive structure, an \"agger-wall\". The article investigates the feasibility of these projects using two case studies: the agger-wall and the house on plot 113W4. Using data from stratigraphic excavation, 3D modelling, Building Information Modelling (BIM), and architectural energetics, the study estimates construction time and labour requirements. <b>Results</b> The aforementioned methods allowed us to estimate the construction of the agger-wall defence line at 11478 p-d (person-day) and the building of the house on plot 113W4 at 187-196 p-d. These figures then need to be put into perspective with an estimated population of 404-538 individuals in the first quarter of the 7th century BC, of whom roughly half are considered fit for construction work and available for it for five to six months per year. <b>Conclusions:</b> In evaluating the feasibility of early construction projects at Megara Hyblaia, findings suggest that the second-generation population could have built both the fortifications and sufficient housing within a year, without disrupting agriculture or essential tasks.

Real-time data collection plays a critical role in effective flood risk management and decision-making, ultimately enhancing infrastructure resilience. The EU-funded RAMOBRIS (Risk Assessment and Monitoring for Bridges under Scour Hazard) project investigated cost-effective monitoring approaches to develop a novel, multidisciplinary strategy for assessing the risk of critical bridges exposed to scour. This manuscript outlines the monitoring strategy developed during the project, with a focus on the application of cost-effective sensors for hydraulic monitoring. The adopted methodology employs an indirect approach using low-cost remote sensing sensors to assess hydraulic properties and estimate scour depth through advanced formulas. Two pilot case studies were conducted on high-risk masonry bridges over the River Nith in Scotland. Various sensors were installed to evaluate their effectiveness in capturing hydraulic data and monitoring scour dynamics. Data from low-cost sensors were evaluated against data collected from higher-cost sensors or other available datasets. The results showed that low-cost sensors for measuring water levels provided accuracy comparable to high-cost radar systems, while being more cost-effective and easier to install. Video data from solar cameras enabled extensive measurements of surface velocity and discharge, improving the understanding of flow dynamics. The study confirmed the feasibility of using image velocimetry techniques for long-term estimation of river velocity and discharge, although further validation is required.

Artificial Intelligence (AI) and Big Data (BD) have altered several industrial sectors providing novel and affordable solutions that facilitate and improve existing operations in these sectors. Hence, the combination of the CCAM paradigm with AI methodologies based on BD could ever increase the potential benefits of CCAM in the contemporary society. For this reason, three CCAM services, which are based on AI and BD, are introduced in the current research work in order to tackle three well-known issues of mobility such as i) the estimated time of arrival, ii) the passenger demand prediction and iii) the mobility patterns identification. The proposed CCAM services were tested on various pilot sites of the EU-funded SHOW project, thus demonstrating the potential of BD and AI in future mobility services.</p>","PeriodicalId":74359,"journal":{"name":"Open research Europe","volume":"5 ","pages":"24"},"PeriodicalIF":0.0,"publicationDate":"2025-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12744199/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145859606","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}
