<https://data.amerigeoss.org/dataset/4f2ee3c5-756b-4424-b4cd-1513ea380cb7> a dcat:Dataset ;
    dct:description "Dataset and scripts supporting the article \"D-to-A_eff converter\", a proceeding presented at the NCSLI Workshop & Symposium 2022, Grapevine TX.The dataset consists of two main parts:  dimensional measurements and conversion scripts.  The dataset and scripts produce an estimate for the effective area and distortion coefficient of the piston-cylinder assembly PCA2062 based on the 2020 dimensional characterization.The dimensional measurements of straightness, roundness, and two-point diameter for the piston and cylinder are in the text files:  \"straightnessPis.txt\", \"straightnessCyl.txt\", \"roundnessPis.txt\", \"roundnessCyl.txt\", \"radiusPis.txt\", \"radiusCyl.txt\"The main conversion script is:  \"CalcAeff2062.py\"This calls two other scripts to find the generatrixes of the piston and cylinder:  \"findGcyl2062.py\" and \"findGpis2062.py\"The conversion also relies on finite-element calculation.  These scripts are in the directory /fea.  All scripts and data from the /fea directory are controlled by the main conversion script CalcAeff2062.py.  To run the finite-element software will require a software license." ;
