The Norwegian University of Science and Technology (NTNU) is offering a 3-year PhD position in ultrasound and signal processing. The theme is non-destructive testing in pipelines and the project is a collaboration with the industrial company Halfwave, a dynamic young company gathering experts in ultrasound technology.
The project is part of Centre for Innovative Ultrasound Solutions (CIUS) a Centre for Research-based Innovation (SFI) funded for 8 years by the Research Council of Norway. CIUS is a collaborative effort between 11 ultrasound industry companies, 3 universities and a university college, SINTEF, and 5 public health partners. CIUS has large multidisciplinary research environment across geographical locations; at NTNU, Trondheim; The University of Oslo (UiO), Oslo; and the University College of South-East Norway (USN) in Horten.
In this project the candidate will acquire a deep understanding on the propagation of acoustic waves in solid materials (pipelines) and how anomalies such as cracks can influence their propagation. She/he will study aspects of sound propagation to improve the sensitivity of acoustic waves to such defaults. The candidate will use simulation tools such as COMSOL Multiphysics to model the propagation of sound waves in pipes and validate these with experimental data.
The candidate will be affiliated to NTNU in Trondheim and has the main supervisor at NTNU, has day-to-day supervision at UiO in Oslo, all in close collaboration with HalfWave (also located in Oslo).
Workplace: Oslo; at the group for digital signal processing and image analysis at the Faculty of Mathematics and Natural Sciences, UiO. It is also expected that the candidate travels frequently to NTNU in Trondheim and spends time with the corporate partner HalfWave.
Detailed description of the project
Stress corrosion cracking poses a serious threat to pipeline integrity. To mitigate this risk, oil and gas operators spend significant capital in inspection of pipelines. The current tools, however, are reported to have issues with the sensitivity and sizing of small cracks especially for gas pipelines. Halfwave has been using ultrasound and the half-wave resonance in gas pipes to detect surface anomalies for some years now. Recently they observed that the waves generated inside the pipe wall propagated a significant distance along the pipe and were sensitive to material inhomogeneities such as cracks. Preliminary theoretical studies and experiments show promising results for the use of guided waves to detect cracks in the wall of gas pipes. The aim for this PhD project is to bring deeper understanding of the experimental results, conduct new experiments and simulations to foster new concepts, and explore new analysis methods.
The successful candidate holds an MSc degree in acoustics, physics, mathematics, signal processing, electronics, or computer science with an emphasis on wave physics and signal processing. CIUS aims to be a world-leading center for research and innovation in next-generation ultrasound technologies. Candidates for this position will be selected in accordance with this aim and expected to be in the upper segment of their class with respect to academic credentials.
Good analytical and programming skills are essential. It is imperative that the candidate has a proven ability to work in an experimental setting and is willing and interested in doing laboratory work. Besides technical skills, we are looking for a curious, ambitious candidate who is highly motivated to do research and contribute to the work carried out in CIUS. Good communication skills in both oral and written English are expected. We strongly encourage that the application is accompanied by a short cover letter explaining briefly how the applicant's background and education fit the goals and requirements of this project.
Appointments are made in accordance with the regulations in force regarding terms of employment for Ph.D. candidates issued by the Ministry of Education and Research, with relevant parts of the additional guidelines for appointment as a Ph.D. candidate at NTNU.
