Abstract. This paper analyses the use of BIM in heritage buildings, assessing state-of-the-art and finding paths for further development. Specifically, this work is part a broader project, which final aim to support stakeholders through BIM. Given that humidity one major causes weathering, being able detect, depict forecast it, key task. A model building – enhanced with integration weathering forecasting will be give detailed information on possible degradation patterns, when they happen....

Abstract Plasticiser loss is a topic frequently mentioned in discussions on the degradation of plastic artefacts museum collections, particularly for plasticised poly (vinyl chloride) and cellulose acetate. Plasticisers may migrate to plastic’s surface remain as deposit, or volatilise into surrounding environment, both presenting an aesthetic issue impacting future stability plastic. This paper draws work conservation science, materials degradation, indoor air quality/emissions studies,...

Abstract Crowdsourced images hold information could potentially be used to remotely monitor heritage sites, and reduce human capital resources devoted on-site inspections. This article proposes a combination of semantic image segmentation photogrammetry changes in built sites. In particular, this focuses on segmenting damaging plants from the surrounding stone masonry other elements. The method compares different backend models two model architectures: (i) one-stage that segments seven...

The use of VOC analysis to diagnose degradation in modern polymeric museum artefacts is reported. Volatile organic compound (VOC) a successful method for diagnosing medical conditions but date has found little application museums. Modern polymers are increasingly collections pose serious conservation difficulties owing unstable and widely varying formulations. Solid-phase microextraction gas chromatography/mass spectrometry linear discriminant were used classify samples according the length...

Abstract The impacts of climate change on heritage collections in Mediterranean museums are serious and lead to accelerated material degradation, loss value, increasing conservation costs climatisation. Climate scenarios simulation models have been developed predict the extreme average future environmental conditions assess long-term risks caused by global warming for museum buildings their countries, with Egypt being particularly at risk. This paper presents results risk analysis indoor...

Abstract Historic objects made of cellulose acetate are potential sources indoor pollution in heritage collections. As these degrade, volatile organic compounds, including acetic acid, produced and emitted. High concentrations acid can increase the degradation rate both inorganic stored nearby. In this study, micro-invasive sampling ion chromatography were used to quantify emission rates from acetate, 3D photographic negatives. It was observed that some degrading emit at high rates, even...

In this work we explore the chemical effects of particulate matter on paper. We exposed paper made pure cellulose to environment in different locations central London, outdoors (in sheltered conditions) and indoors, for a period up 6 months. monitored (PM) deposition by counting particles deposited every month with scanning electron microscope. analysed elemental composition using inductively coupled plasma mass spectrometry. After accelerated degradation samples, determined degree...

Abstract Since the introduction of Oddy test in 1973, many museums and cultural institutions have put method use, developing their own versions protocols. Currently 3-in-1 version, temperature at 60 ºC 2 g tested material are set as common practice; however, other variables not standardized. The purpose this study is to examine current test, identify differences results derived from variations procedures, ultimately raising awareness within conservation community work together towards a...

This review addresses the use of computational fluid dynamics for interpretation and preservation heritage. Fluid dynamic simulations in heritage field focus mostly on slow air movement indoor spaces they usually involve temperature humidity. Simulations have different roles: may be exploratory, used to support preventive conservation occasionally aid historical or archaeological interpretation. The research questions rarely testing development new mathematical formulations; instead,...

Abstract Archival boxes are used as a preventive measure to control the microenvironment in museums and archives storages. However, their efficiency protecting valuable artefacts from fluctuations relative humidity (RH) is not yet fully understood. In this study, environmental performance of different archival with configurations (size, design, presence holes/paper material, cardboard types, surface modification) was included evaluation internal environment (RH). The effectiveness on...

Abstract This research assesses the precision, repeatability, and accuracy of crowdsourced scientific measurements, whether their quality is sufficient to provide usable results. Measurements colour area were chosen because possibility producing them with smartphone cameras. The measurements was estimated experimentally by comparing data contributed anonymous participants in heritage sites reference known precision. Participants performed taking photographs smartphones, from which...

This study examines methods of geographic features recognition from historic maps using CNN and OBIA. These two are compared to reveal which one is most suitable be applied the dataset Banda Islands, Indonesia. The characteristics cartographic images become main challenge in this study. divided into buildings, coastline, fortress. results show that superior OBIA terms statistical performance. Buildings coastline give excellent for analysis, while fortress harder interpreted by model. On...

Abstract The COVID-19 pandemic has had a profound impact on almost all aspects of society. Cultural heritage sites, which are deeply intertwined with the tourism industry, no exception. direct impacts virus population, as well indirect impacts, such government-mandated measures including social distancing, face coverings, and frequent temporary closures have greatly impacted visitor experiences at sites. To quantitatively evaluate these from perspective visitors, we collected 1.4 millions...

Abstract The Oddy test is an accelerated ageing used to determine whether a material appropriate for the storage, transport, or display of museum objects. levels corrosion seen on coupons silver, copper, and lead indicate material’s safety use. Although conducted in heritage institutions around world, it often critiqued lack repeatability. Determining level manual subjective process, which outcomes are affected by differences individuals’ perceptions practices. This paper proposes that more...

For the last 30 years, cultural heritage sector has undertaken research into pesticide residues in museum objects. However, quantitative studies of volatile remain scarce. This presents an active air sampling methodology to obtain qualitative and data for naphthalene as most common found sampled The procedure comprises placing contaminated objects inside a chamber fitted with sorbent tube filled TENAX, then connected via tubing calibrated pump. sample is desorbed analysed using automated...

This paper proposes citizen heritage science as an effective method to gather reliable data for monitoring and documenting sites. For large organisations the documentation of sites in their care presents considerable challenges; continual smaller, unstaffed, more remote is often not practical. However, are popular destinations that receive high levels visitors who carry increasingly sophisticated mobile phones. It seems logical capitalise on using visitors' images record monitor We compare...
