To do this, we used the FracLa[...]texto impreso
Sijilmassi, Ouafa ; López Alonso, José Manuel ; Río Sevilla, Aurora, del ; Barrio Asensio, María del Carmen | Elsevier | 2020-05-30The aim of this work is to study local changes of fractality in mouse embryonic lens. Embryos were removed from female mice that have been subjected to a diet deficient in folic acid for two and eight weeks. The local change of fractality is stu[...]texto impreso
Photonic crystal microcavities are defined by the spatial arrangement of materials. In the analysis of their spatial temporal mode distributions Finite-Difference Time-Domain (FDTD) methods have proved its validity. The output of the FDTD can be[...]texto impreso
Finite-difference time-domain (FDTD) algorithms are affected by numerical artifacts and noise. In order to obtain better results we propose the use of the principal component analysis based on multivariate statistical techniques. It allows a str[...]texto impreso
