FLOreS - Fractional order loop shaping MATLAB toolbox

Autor: van Duist, Lennart, van der Gugten, Gijs, Toten, Daan, Saikumar, Niranjan, HosseinNia, Hassan

A novel toolbox named FLOreS is presented for intuitive design of fractional order controllers (FOC) using industry standard loop shaping technique. This will allow control engineers to use frequency response data (FRD) of the plant to design FOCs by

Continuous reference intervals for pediatric testosterone, sex hormone binding globulin and free testosterone using quantile regression

Autor: Daniel T. Holmes, J Grace van der Gugten, Benjamin Jung, Christopher R. McCudden

Publikováno v: Journal of Mass Spectrometry and Advances in the Clinical Lab, Vol 22, Iss , Pp 64-70 (2021)

Testosterone (T), sex hormone binding globulin (SHBG), free testosterone (FT) and bioavailable testosterone (BAT) are commonly employed tests in pediatric endocrinology and all require age-dependent reference intervals for interpretation. The common
