Determination of the Anthropometric Measures of the Lips by Age Groups in the Mestiza Population.

Measurements from a certain population may show a similar pattern that allows an alteration to be easily recognized and enable a better surgical approach. In our population, the changes in the anthropometric measurements of the lips are unknown, so our objective is to determine the variations in these measurements by decades of age to achieve a better aesthetic and reconstructive surgical approach. Anthropometric measurements of the lips were taken with a vernier in relation to the previously marked anatomical points.

Wavelet transform and cross-correlation as tools for seizure prediction.

This paper describes the detection of preictal bursting using wavelet transform application and cross-correlation analysis. The wavelet transform is applied to data reduction and signal pre-processing. The extracted features provide simplified signals to process by means of the cross-correlation technique.

Photoluminescence quenching effect on porous silicon films for gas sensors application.

Porous silicon (PS) films were investigated by Raman, and photoluminescence (PL) spectroscopies using different laser excitations: 488.0, 514.5, 632.
