PhD scholarship within the use of machine learning for CT-scanning of wood
Apply for this job
About the position
Faculty of Environmental Sciences and Natural Resource Management at Norwegian University of Life Sciences (NMBU) has a vacant 3-year PhD–position related to the use of artificial intelligence for CT-scanning of wood.
Industrial computer tomography (CT) scanning of logs is becoming a more widespread tool in sawmills and has proven to considerably increase the volume of high-value sawn timber. CT-scanning of logs provides information on the interior structure of the logs before sawing, and this information can be used when optimising the yield of sawn timber.
Wood is a natural material, and the properties depend on growth and development of the trees in the forests. This applies in particular to knot properties, which are highly dependent on the crown development of the trees. Size of knots and whether knots are sound or dead are important factors for the quality of sawn timber products. These properties can be detected with CT-scanning, but the current technology provides only limited accuracy in cases with low contrast in the CT-images.
We seek a PhD candidate who will apply machine learning techniques to detect knots from CT-images of logs. Datasets containing information about knot properties, forestry data and CT-scanning images will be recorded. The candidate will investigate whether the algorithms for knot detection by CT-scanning can be improved by using machine learning, and by combining data from the forest with data obtained from CT-scanning. By following these goals the PhD candidate will help us develop an artificial intelligence framework to improve the sawmilling industry’s ability to utilise the forests’ natural resources more efficiently and more sustainably.
The position is part of the project «Wood Artifcial Intelligence —Knot Modelling by Computed Tomography», which is a cooperation between Sweden, Germany and Norway. Some of the work might be done at Luleå University of Technology in Skellefteå, Sweden.
The applicant is made aware that an application for a PhD position at NMBU is at the same time an application for admission to a PhD program at the institution. The documentation that is necessary to ensure that the admission requirements are met must be uploaded as an attachment.
- Procure data on knot properties to be used for statistical modelling and for training of machine learning models
- Develop models describing knot diameter and distribution of sound and dead knots in Norway spruce and Scots pine
- Develop machine learning models for the detection of knot properties from CT-scanning
The successful candidate is expected to enter a plan for the progress of the work towards a PhD degree during the first months of the appointment, with a view to completing a doctorate within the PhD scholarship period.
