This essay continues the investigation of an earlier article, also published in this journal, by examining artistic representations of Cuauhtémoc in the post-revolutionary period, and especially after 1940, when the figure of the last Aztec king became widely and variously…

The use of several techniques for non-destructive testing is a common strategy for detecting and classifying flaws in aluminium material. Techniques like multiresolution data analysis and data classifiers are valuable for obtaining as much information as possible from the flaws.…

The present paper shows a single and original measurement circuit, using instantaneous and average readouts of the chaotic dynamic of a Chua's circuit Vc1(X1) signal with binary decryption, synchrony qualification and chaotic sequence applications. The circuit was simulated (Workbench), developed…

This paper presents design hints in CMOS ring oscillators based on NOT gates. The NOT gate is used as vehicle to introduce basics on signal propagation and also to present simple design models. Both simulation and experimental results are presented…

This paper presents a wireless communication protocol based on the Earliest Deadline First policy for wireless body sensor networks. This work advances a previous effort by proposing using an implicit Earliest Deadline First policy to guarantee real-time communication by optimizing…

A brief perspective of the development of the density functional theory of chemical reactivity since the identification of the chemical potential with the electronegativity in 1978 is presented. The reactivity concepts are examined together with the chemical principles associated with…

The effect of 2,5 and 2,6 disubstitution (R = CH3, Cl, C(CH3)3) for 1,4-benzoquinones, in the reorganization energy (λ) for the first electron uptake process was analyzed in acetonitrile solution. Data obtained by cyclic voltammetry suggested differences in λ for…

Electron correlation effects on atomic basin populations of AIM theory and the resulting de/localization of the basin charge and momentum densities, as measured by local Shannon entropies and basin kinetic energies, are discussed for a series of ten- , fourteen-…
