With the growth of the aeronautical industry worldwide, it is important task for the next generation of air traffic control systems generating technologies that reduce risks and maintain a constant monitoring of atmospheric meteorological phenomena. Many meteorological phenomena generate risks and delays in air operations. An objective here is to provide an overview of the main meteorological processes...
This paper evaluates the accuracy of different characterization methods for the automatic detection of multiple speech disorders. The speech impairments considered include dysphonia in people with Parkinson's disease (PD), dysphonia diagnosed in patients with different laryngeal pathologies (LP), and hypernasality in children with cleft lip and palate (CLP). Four different methods are applied to analyze...
The color is a feature derived from perceptual light that is reflected on objects, as such, represents a physical property. However, progress has been made in building mathematical models to define it more clearly. Light sources play an important role in the perception of colors and one of the measures to characterize their effect is the Correlated Color Temperature (CCT). The CCT is a measure used...
This paper presents a study of biometric identification using a methodology based on complexity measures. The identification system designed, implemented and evaluated uses nonlinear dynamic techniques such as Lempel-Ziv Complexity, the Largest Lyapunov Exponent, Hurst Exponent, Correlation Dimension, Shannon Entropy and Kolmogorov Entropy to characterize the process and capture the intrinsic dynamics...
