Deep learning (DL) methods are applied to detect deterioration and damage by automating vision-based monitoring. This study uses the You Only Look Once (YOLO), method to detect deterioration in tiles automatically. To obtain the initial dataset, over 5000 images of damage were collected, including cracks, craters, glaze detachment, and tile lacunae, as well as images with no defects. Additionally, a MobileNet model was used for binary classification of damaged and intact tiles to compare classification and detection approaches. Through the fine-tuning of hyperparameters and updating the dataset, an overall accuracy of over 72% for YOLO (multiple classification) and 97% accuracy for binary classification was achieved, demonstrating the adequacy of the tool for real-world applications.</p></div>","PeriodicalId":15480,"journal":{"name":"Journal of Cultural Heritage","volume":"68 ","pages":"Pages 86-98"},"PeriodicalIF":3.1,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1296207424001067/pdfft?md5=dd50077783083e12e7f3f4ad6600bb0f&pid=1-s2.0-S1296207424001067-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141241039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, on a quarter of all tested materials, we performed a SurveNIR analysis, providing information regarding paper pulp type, lignin, protein and rosin content, degree of polymerization, and mechanical properties. The archival material was grouped into three periods characterising the three milestones in paper production: handmade gelatine-sized rag papers, machine-made rag papers with gelatine and rosin sizing, and papers made from processed wood pulp.</p><p>Regarding the manuscripts’ inks, we used iron and copper tests to determine the presence of Fe², Cu²⁺ and Cu⁺ions, respectively. For the visual characterization and condition rating of the inks, we used the protocols described by the Netherlands Institute for Cultural Heritage.

The inks are not severely corroded, and there is no loss of text, although 20 % of the collection does show signs of iron-gall ink (IGI) corrosion. A limited number of documents, mostly before 1800, would require local antioxidative treatment. Due to the low pH of all the papers and the detection of ink corrosion, the collection should be stored in a cool environment, with low relative humidity.</p><p>After the survey, digitisation priorities were also established.</p></div>","PeriodicalId":15480,"journal":{"name":"Journal of Cultural Heritage","volume":"68 ","pages":"Pages 47-58"},"PeriodicalIF":3.1,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1296207424000992/pdfft?md5=3c0fcf3ab80bf7f8e70968985c60a034&pid=1-s2.0-S1296207424000992-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141243258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the mechanisms at play through systematic experimentation. It was found that humidity cycling enhances the dimensional stability of the mounting by diminishing its hydroexpansivity and irreversible shrinkage. Specifically, humidity cycling induces fiber hornification, which reduces the hydroexpansivity of the mounting.

However, related research, specifically on the transformed compositions and structures of archaeological amber, has been limited due to complexities in deciphering the intricate components. In this research, attenuated total reflection Fourier transform infrared (ATR-FTIR), X-ray fluorescence (XRF), inductively coupled plasma optical emission spectroscopy (ICP-OES) and pyrolysis–gas chromatography/mass spectrometry (Py-GC/MS) were applied on geological and archaeological Baltic amber to find the ageing pathways.
