This paper demonstrates an additional application of CT data sets. We namely show how the data can be processed and converted to interactive, computer-animated models embedded in web applications to bring back the historical objects to novel virtual life. This opens up a new way for museum visitors to interact with the virtual objects in both on-site and online exhibitions. The use of freely accessible software at all stages ensures that the involved costs remain accessible to public institutions. The approach is demonstrated using three technical instruments of historical significance spanning three centuries of maritime navigation: a pocket sundial, a maritime chronometer, and a pocket barometer manufactured in the 18th, 19th and early 20th centuries. Each object presents its own attributes and characteristics that require different approaches and solutions along the data process chains. The outcomes of these chains are interactive applications demonstrating the functionalities of the old instruments. This contributes to a better understanding of their modes of operation, and can focus the attention of the visitors to individual technical details, material composition and appearance, or other attributes of historical significance. The accessibility and appeal of the virtual objects results in a more immersive interaction experience facilitating a better transfer of knowledge to the visitors.</div></div>","PeriodicalId":15480,"journal":{"name":"Journal of Cultural Heritage","volume":"76 ","pages":"Pages 100-110"},"PeriodicalIF":3.3,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145155848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, we proposed a data augmentation framework based on the Wasserstein Generative Adversarial Network with Gradient Penalty (WGAN-GP) to extend the NIR spectral data of WAW and associated physico-mechanical parameters - maximum water content (MWC), basic density (BD), modulus of rupture (MOR), and fracture strain (FS). Tree-based ensemble learning models (LGBM and Multi-Scale Derivative Enhanced Gradient Boosting Machine, MSDE-GBM) were built using the data generated by WGAN-GP, and the effect of extended dataset size on model performance was systematically investigated. The results showed significant correlations among the four physico-mechanical parameters of WAW, validating the feasibility of a multi-target generation mechanism to simultaneously synthesize spectral data corresponding to MWC, BD, MOR, and FS. Analysis of the generated data revealed that the WGAN-GP-generated spectral data exhibited significant noise during the initial training epochs; however, the morphology and smoothness of the synthetic spectra progressively approximated the real data with increasing training cycles, improving both diversity and authenticity. Further experiments identified optimal training epochs for different augmented dataset sizes: 4000 epochs for datasets expanded to 300 and 900 samples, and 6000 epochs for the 600-sample dataset. Subsequent modeling using data generated at these optimal epochs confirmed that WGAN-GP augmented datasets significantly improved the performance of LGBM and MSDE-GBM in predicting MWC and BD. Compared to the original dataset, the optimal models achieved RMSE reductions of 47.9 % (LGBM) and 59.9 % (MSDE-GBM) for MWC, 29.2 % (LGBM) and 13.3 % (MSDE-GBM) for BD. In contrast, the lower prediction accuracy for MOR and FS (R²&lt; 0.7) highlighted the complex mapping relationships between micro-scale mechanical parameters (tested via thermomechanical analysis, TMA) and NIR spectral data.

This study employed confocal Raman spectroscopy, SEM, and EDS to analyze three corrosion samples from the iron oxen group. The objectives were to characterize the compositional profiles of corrosion products and elucidate the corrosion-mineralization interplay. The results demonstrate that low-mineralization corrosion samples predominantly contain α-FeOOH (goethite), β-FeOOH (akaganéite), γ-FeOOH (lepidocrocite), and uncorroded ternary phosphide eutectic structures, with significant graphite aggregates observed within the rust layers. The distribution of β-FeOOH exhibits a certain correlation with that of chlorine (Cl), as expected given its chloride-incorporating nature. High-mineralization corrosion samples are dominated by α-FeOOH and Fe₂O₃ (hematite), where the Fe₂O₃ content decreases with increasing corrosion depth. The phosphorus eutectic structures (steadite) suggests that under alkaline conditions, steadite could form a passivation film, thereby halting further corrosion progression. The non-ferrous minerals are primarily composed of silica (SiO₂), albite (NaAlSi₃O₈), and calcite (CaCO₃), with silica predominantly distributed within highly mineralized porous rust layers and macroscopic fissures. Their formation mechanisms potentially reflect early-stage geochemical processes—specifically albitization, silicification, and calcification—during geological sedimentation.

The research aims (1) to clarify how the notion of value is defined and to map the recognised value typologies and those for which the definition exists, as well as (2) to identify the main approaches to cultural heritage preservation and their relationship to the notion of value. A comprehensive content analysis was conducted on a curated sample of 34 seminal documents sourced from UNESCO, ICOMOS, ICCROM, the Council of Europe, and the Architects’ Council of Europe, all of which explicitly define “value” in the context of cultural heritage. The results systematically highlight the complexity of the notion of value – its meaning and scope, as well as the representation of the previously identified main approaches to cultural heritage preservation within the analysed seminal documents. The results reveal substantial variation and evolution in the definition and understanding of the notion of value, with over 151 distinct value typologies identified; however, only a handful—cultural, historical, social, and aesthetic values—predominate across the analysed sources. Furthermore, the study identifies four main approaches to cultural heritage preservation: material-based, value-based, living heritage, and historic urban landscape. The findings demonstrate that the evolution of these approaches corresponds directly to changes in how values are conceptualised and operationalised, particularly regarding the balance between tangible and intangible values and the expanding role of different stakeholder groups. The study highlights a persistent lack of consensus regarding the definition of the notion of value and classification of values in cultural heritage preservation discourse. This multiplicity raises critical questions about the coherence, inclusivity, and cultural adaptability of current valuation practices. Rather than proposing a unified model, the paper offers a critical reflection on the institutional and epistemological frameworks – foundational sources published by renowned international organisations that still serve as a global guideline for identifying and preserving values of cultural heritage in practice. Moreover, the identification and examination of the ideas and principles of the four main approaches to cultural heritage preservation serve as a starting point for further, more context-based analysis of the notion of value. These insights aim to inform future discussions on redefining the notion of value – its meaning and scope in cultural heritage policy documents - moving beyond rigid typologies toward more dynamic, contextually sensitive, and inclusive approaches.</div></div>","PeriodicalId":15480,"journal":{"name":"Journal of Cultural Heritage","volume":"76 ","pages":"Pages 52-64"},"PeriodicalIF":3.3,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145107157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate the performance, we compared the methodology with five state-of-the-art models on the created datasets, which contained 4888 samples. A comprehensive evaluation of diverse X-ray images from various artworks demonstrates the effectiveness of our approach in practical applications. The newly developed ForgAnoNet achieves an accuracy of 98.08 %, significantly outperforming all other models in the study.
