About the position

For a position as a PhD Candidate, the goal is a completed doctoral education up to an obtained doctoral degree.

We are looking for a PhD candidate for one of 13 PhD positions in Marie Sklodowska-Curie Action (MSCA) CHARM (Conservation of Heritage Architecture, buildings and sites by Resilient Methods: hydro-climate factors) project. The main objective of CHARM MSCA Doctoral Network project is to develop new sustainable conservation and restoration solutions, adapted to the current and future climate conditions, designed in a circular economy philosophy, having a low environmental footprint and high handprint. CHARM also responds to socio-economical requirements of wellbeing and proposes conservation/restoration solutions economically acceptable and respecting the cultural value of buildings.

CHARM proposes a holistic approach including:

• Site observation and data collection
• Data preparation to be used by AI, models, etc
• Methods for understanding and modelling past and future degradation of architectural heritage
• Sustainable conservation solutions to several observed problems
• Assessment of the impact of architectural conservation on the environment and of the environment (past, present and future) on architectural heritage
• Bidirectional interactions with society proposing risk management plans but also taking into account the society wills and needs

The vision of CHARM MSCA project is to educate young and talented scientists towards a combined high-level experimental and data driven approach for the early-stage accurate, precise detection of hydro-climate impact on cultural heritage, to answer to recruitment needs in time of climate change and natural hazards impact about research and innovation in the sector of cultural heritage conservation and restoration. 

CHARM network gathers excellent academic centers that have decennial experience in the field of risk assessment, adaptation and mitigation solutions to the climate change impact, conservation of cultural heritage and restoration, documented by scientific papers published in high impact-factor journals, and by previous EU funded research projects. CHARM puts together researchers from universities and research organisms, national and local organizations in charge of Cultural Heritage conservation, Small and Midsize Enterprises, industrial producer of building materials, and Non-Governmental Organization, from 9 European and 1 South American countries.

Description of DC2 PhD position

Project title: Understanding conservation condition and rehabilitation needs at district scale in time of energy saving and climate change via machine learning driven method

Topic in brief:

The aim is to implement an approach based on artificial intelligence (AI) in the form of CNN to automatically detect cracks and morphological indices in order to manage the large amount of data obtained from Synchrotron and SEM images. This automatic tool will allow the analysis of a large number of samples to statically quantify the indices characterizing healthy and pathological bones. The AI-tool permits to classify the physio-pathological conditions, as an aid in the clinical diagnosis.

Objectives:

This doctoral project aims to develop deep learning neural networks to investigate data in available database (e.g., EU building stock observatory and other similar database) to

1. classify building stock at district scale more prone to decay based on buildings construction year, location, main constitutive material, exposure, use and
2. to predict potential maintenance and restoration priority based on (i) and existing energy retrofit directive and/or risk maps 

Expected results:

(i)to build high-quality dataset highlighting the façade that is more prone to decay at district/city level from existing raw database; 

(ii) to apply deep learning neural networks (e.g., convolutional neural network) to perform semi-automatic decay pattern segmentation and associated mapping; 

(iii) to correlate the maintenance of buildings at district/city level with decay patterns/features at district scale to prioritize large scale intervention; and 

(iv) to optimize the maintenance activities by leveraging these correlations learned by machine-learning based approaches. 

Supervisory Committee:

• Main supervisor: Full prof. Chiara Bertolin, Norwegian University of Science and Technology (NTNU), Department of Mechanical and Industrial Engineering (MTP) (Academic)
• Co-supervisor: Associate prof. Chao Gao, Norwegian University of Science and Technology (NTNU), Department of Mechanical and Industrial Engineering (MTP) (Academic)
• Mentor: Dr. Marie Louise Anker, Department Director at Nidaros Cathedral Restoration Works. (Non.Academic)
