Development and evaluation of image-series for portion size estimation in dietary assessment among adults
2021
AbstractPortion size images are advantageous in dietary assessment. The aim of the present study was to develop and validate new culturally specific image-series for portion size estimation to be used in a new Norwegian version of a British web-based dietary assessment tool (myfood24). Twenty-three image-series of different foods, each containing seven portion size images, were created and validated in a group of adults (n41, 58 % female) aged 19–44 (median 23), out of which 63 % had higher (tertiary) education. The participants compared 46 portions of pre-weighed foods to the portion size images (1886 comparisons in total). Portion size estimations were either classified as correct, adjace…

The total uncertainty covariance matrix for the average relative $p_T$ per jet $p_T$ bin. The covariance matrix is the sum of the covariance matrices for each source of systematic and statistical uncertainty. Note that the overall sign for the systematic uncertainty covariances is arbitrary.

The total uncertainty covariance matrix for the fragmentation function. The first half of the bins on a given axis correspond to the more central jet while the second half correspond to the more forward jet. See Fig. 4 in the paper for more information about the binning. The covariance matrix is the sum of the covariance matrices for each source of systematic and statistical uncertainty. Note that the overall sign for the systematic uncertainty covariances is arbitrary.
