Tony Davies Column

The Tony Davies Column alternates between chemometrics and data handling and standards, as well as a wide range of EU and other initiatives across the whole of spectroscopy.

Tony-DaviesTony (A.N.) Davies has been a columnist for Spectroscopy Europe since its inception. Together with Tony (A.M.C.) Davies he has produced the “Tony Davies” column until Tony’s retirement in 2014. Tony (A.N.) is Lead Scientist with AkzoNobel RD&I Expert Capability Group in Measurement and Analytical Science in Deventer, The Netherlands and is Professor of Analytical Science at the University of South Wales in the UK.

 

The last furlong (2) Data Compression by wavelets

TD-25-4-F1-sNow that Tony understands wavelets, he is in the perfect position to explain them to the rest of us! Whilst wavelet compression is an interesting and popular method, it is worth confirming that there is a real benefit in using them compared to FT compression, especially for near infrared spectra where there are few regions of flat baseline.

GHz NMR

TD-25_3-F1-sTony (A.N.) Davies is getting excited by GHz NMR. These new high fields offer tantalising new areas of research but at a cost that generally requires their purchase by Government-funded centres of excellence. He argues that continued funding of such projects is essential, especially in difficult economic times.

The last furlong: 1. Data compression

TD-25_2-F3-sTony (A.M.C.) Davies starts a review of the chemometric ideas that have most excited him over the last 30 years. In this column, he looks at the use of Fourier transformation for data compression. FT can also provide the side benefit of reducing high-frequency noise.

COAST

TD-25-1-sTony (A.N.) and Henk-Jan van Manen introduce us to the COmprehensive Analytical Science and Technology (COAST) initiative, a funding effort to counteract what was seen by industry and academia as a decline in fundamental analytical research in the Netherlands and the associated problems around producing high quality researchers and technicians.

Variable selection for regression analysis: an up-date on an old problem

TD-24-6-F7-sTony (A.M.C.) Davies and Tom Fearn describe an enhancement of the popular partial least squares (PLS) technique, powered partial least squares (PPLS),  that has shown significantly better results.
