Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- A comprehensive study has been launched in the medieval fortress of Carcassonne involving a cooperation between the universities of Umeå and Rennes, and the research institute of IRSTEA of Montpellier. This study aims to combine several spectroscopic techniques in order to resolve archaeological problems related to which raw materials were used during the city wall construction, and also to improve our understanding of the different phases of construction and use of the city walls. This study was also used for elucidating the different qualities and weak points of the applied field methods.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Commercial digital cameras can be converted into a tool for NIR field multivariate imaging. Results obtained using such a tool are far less sophisticated than those obtained by NIR spectrometers or hyperspectral imagers but they may often be useful enough for making quick conclusions during field work.

Myth: Light travels to and from the sample in a fibre-optic cable without problems

Annan publikation (populärvet., debatt m.m.)abstract
- This myth addresses spectral artefacts arising from the use of fibre-optic cables, typically used in multi-point Fourier transform near infrared (FT-NIR), diode-array or dispersive systems. It is tempting to assume that light travels in an optical fibre without challenges and that the fibre acts like a perfect optical element allowing us to focus on the spectrometer, sampling, cells and probes-but unfortunately this is not so.

The RPD myth
- 2014

Annan publikation (populärvet., debatt m.m.)abstract
- For a long time, the Mythbusters have harboured a grudge about the ubiquitous use of and blind reliance on the RPD statistic as a tell-all index regarding the quality of any NIR calibration. This feeling is substantiated by the many reviews we, and many others, have performed for the NIR community and other journals over more than the last decade. There are apparently very few reservations regarding this institution: if only RPD≥3... all is well with prediction performance.
