Strathclyde Open Access research that creates ripples...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of research papers by University of Strathclyde researchers, including by Strathclyde physicists involved in observing gravitational waves and black hole mergers as part of the Laser Interferometer Gravitational-Wave Observatory (LIGO) - but also other internationally significant research from the Department of Physics. Discover why Strathclyde's physics research is making ripples...

Strathprints also exposes world leading research from the Faculties of Science, Engineering, Humanities & Social Sciences, and from the Strathclyde Business School.

Abstract

The online measurement of basis weight in paper production is hampered by excessive noise, and the zig-zagging motion of the scanner transversing the sheet. Decoupling variations in the direction of production form variations across the sheet and visa-versa. An algorithm is presented that attempts to reconstruct this two-dimensional data from the single scanner.
