About the Project

Smooth running of machines are vital in all sectors of manufacturing. In recent years much emphasis are put on the development of artificial intelligence techniques to solve issues related to machine condition diagnosis and prognosis. This is now very much in the heart of smart manufacturing. To avoid the burden of much storage requirements and processing time, compressive sampling with correlated principal and discriminant components for bearing faults diagnosis based on compressed measurements has been proposed. The project will review existing techniques and develop new and improved ones. Aims are to achieve high classification accuracies, reduced computation time, and storage requirement, with fewer measurements.
This project will involve programming, signal processing, machine learning, mathematical analysis, and good writing ability for presentation of technical work. An ideal candidate will have a very good Master degree or a First Class Bachelor degree.

Funding Notes

Brunel offers a number of funding options to research students that help cover the cost of their tuition fees, contribute to living expenses or both. See more information here: https://www.brunel.ac.uk/research/Research-degrees/Research-degree-funding. Recently the UK Government made available the Doctoral Student Loans of up to £25,000 for UK and EU students and there is some funding available through the Research Councils. Many of our international students benefit from funding provided by their governments or employers. Brunel alumni enjoy tuition fee discounts of 15%.)
