CT image quality parameters were evaluated with two different software resources, CTQA_cp and Catphan QA (Image Owl, Inc., Greenwich, NY, USA), in order to cross-check the obtained results and validate CTQA_cp results with a reference.
The designer can modify the design condition interactively by checking the obtained diagram.
The authors are aware of the fact that there are many other optimization methods, like the cascade optimization or the ideal point discriminant analysis [1], and have indeed checked the obtained results using some of the mentioned methods, obtaining similar results.
In all renal biopsies performed by radiologists, a nephrology fellow has observed the whole process of the procedure and checked the obtained specimens with naked eye.
Moreover, we also emphasize the fact that this study evaluation was conducted by peer review, analysing discrepancies and seeking agreement, despite this method entailed, in some cases, double-checking the obtained information from the colonoscopy requests, and from the electronic medical records.
In order to check the results obtained with the microarray, the archaeal community structure of the same digester was analysed by 16S rRNA gene cloning and sequencing.
This process would allow considering the three vector field components, some global scale regularization to be introduced if needed, and to double check the model obtained by the fast spherical transform.
Remark 1 In Theorem 2, we can easily check the condition obtained by using the new method if the dynamic system is given and the positive constant m is well chosen.
In order to reconfirm and cross check the results obtained from FA we also perform a Hierarchical Cluster Analysis (HCA) [40], which has similar concepts of grouping of variables with underlying common behavior.
