Comparing apples and oranges? A critical look at research on learning from statics versus animations
(Pergamon-Elsevier Science, 2016-11)
Many of the studies that have compared the instructional effectiveness of static with dynamic images have not controlled all the moderating variables involved. This problem is present not only in instructional pictures ...
Hot Brownian carriers in the Langevin picture: Application to a simple model for the Gunn effect in GaAs
(2013-09-23)
We consider a charged Brownian gas under the influence of external, static and uniform electric and magnetic fields, immersed in a uniform bath temperature. We obtain the solution for the associated Langevin equation, and ...

Dynamic multiple-image encryption based on chirp z-transform
(IOP Publishing, 2019-02)
It is demonstrated a dynamic encryption scheme based on chirp − z transform (CZT). The novel design of this setup allows to protect multiple images in a multiplexed format and fully recover them without the influence of ...
Chaos in transit systems
(UniandesDoctorado en IngenieríaFacultad de Ingeniería, 2010)
We present two traffic models based on the same idea: that of a single vehicle interacting with traffic lights. The vehicle is capable of accelerating, traveling at constant speed, and braking. Braking takes place when the ...
Habilidades de leitura de legendas de filmes em escolares do ensino fundamental
(Pró-Fono Produtos Especializados para Fonoaudiologia Ltda., 2010)
TEMA: as habilidades de leitura de textos fixos em escolares são amplamente conhecidas, no entanto ainda não se sabe como os escolares realizam a leitura de textos móveis e quais habilidades são necessárias para este tipo ...
Vortex lattice mobility and effective pinning potentials in the peak effect region in YBCO crystals
(Indian Academy of Sciences, 2006-12)
The peak effect (PE) in the critical current density in both low and high temperature superconductors has been the subject of a large amount of experimental and theoretical work in the last few/several years. In the case ...
Formation of the competitive potential of the agricultural territories

DESCRIPCIÓN DE UN SISTEMA PARA LA MEDICIÓN DE LAS PRESIONES PLANTARES POR MEDIO DEL PROCESAMIENTO DE IMÁGENES FASE I
(Fondo Editorial EIA - Universidad EIA, 2013-10-09)
La medida de la presión plantar es fundamental para conocer la distribución de las fuerzas en la planta del pie. Estos valores son importantes para el diagnóstico y tratamiento de diferentes patologías como úlceras diabéticas ...
