Compared to feature extraction-based methods, the proposed method reduces processing time by approximately 60 %, achieving a stitching time of 42 s for high-resolution images. The proposed method also achieves superior image quality, with information entropy of 6.7, an average gradient of 1.8, and a spatial frequency of 5.0. Additionally, a quantitative evaluation reveals that the proposed method achieves a stitching quality score of 64, surpassing the feature extraction-based method's score of 63, with fewer distortions and improved clarity.

The cross-regional collaborative CDW governance ecological compensation evolutionary game system has four evolutionary stable strategies. Different ecological compensation fees encourage recycling enterprises to actively participate in collaborative governance, but discourage local governments in different regions. Moreover, different ecological compensation fee amounts have heterogeneous effects on the collaborative governance behaviors of the government and recycling enterprises. Further, the synergy coefficients positively affect the cross-regional collaborative governance behaviors of local governments and recycling enterprises. Thus, this study offers new evidence regarding ecological compensation in cross-regional synergistic CDW governance and provides a reference for local governments in formulating effective ecological compensation policies.</div></div>","PeriodicalId":34137,"journal":{"name":"Developments in the Built Environment","volume":"22 ","pages":"Article 100679"},"PeriodicalIF":6.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analytical models are developed to estimate the degradation on compressive strength and elastic modulus with temperature and validated against experimental data.

While various initiatives proposed different LogBook data models, there are still drawbacks, such as heterogeneity and consensus about elements and categories (group of elements), lack of identifying the key DBL elements, lack of effectively incorporating the main elements of EPC, and providing data dictionaries. The main contribution of this ongoing research is to compare the current DBL and EPC data models through a semi-automatic and knowledge-based approach. As a result, a list of matched and unmatched elements per category was created. The comparison list provided information on the available and common elements, most representative categories and elements, and correlation between models.

Currently, rock wool and glass wool are widely used as insulation materials in the building stock across Europe, while in multiple countries are still landfilled at their end-of-life. Within a recent research project, mineral wool waste has proved to be recyclable as a precursor in an alternative binder to carbon-intensive conventional cement, such as alkali-activated materials (AAMs). This open-loop recycling of mineral wool in AAMs is associated with the creation of new value chains within the circular economy that can trigger symbiotic relationships between urban areas and industries. Stakeholders who produce mineral wool waste–based alkali-activated construction materials at a pilot scale in 5 European countries were interviewed to evaluate their environmental, economic and social performance using selected circular economy indicators. Strengths, weaknesses, opportunities, and threats (SWOT) analysis was applied to identify common trends across pilot-scale productions and potential industrial up-scales. While common barriers include limited economic viability at the pilot scale, which can be addressed through industrial upscaling with optimised supply chains, there is also variability in consumer acceptance of waste-based materials across countries. Finally, potential solutions to the identified barriers along each step of the value chain are proposed. The results show that combined actions of industry, cities, and policymakers are required to overcome barriers and nudge the transition towards a circular economy. This can be achieved by using economic incentives to enhance the cost-competitiveness of alternative construction materials, promoting green public procurement, and raising public awareness.</div></div>","PeriodicalId":34137,"journal":{"name":"Developments in the Built Environment","volume":"22 ","pages":"Article 100662"},"PeriodicalIF":6.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143850497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
