Modelación del fenómeno de vibración forzada formulando una analogía eléctrica con el programa de elementos finitos Ansys : Modeling of forced vibration phenomenon by making an electrical analogy with ANSYS finite element software
Designing mechanical systems which are submitted to vibration requires calculation methods which are very different to those used in other disciplines because, when this occurs, the magnitude of the forces becomes secondary ...
Estimation of the Population Total using the Generalized Difference Estimator and Wilcoxon Ranks : Estimación del total poblacional usando el estimador de diferencia generalizada y los rangos de Wilcoxon
This paper presents a new regression estimator for the total of a population created by means of the minimization of a measure of dispersion and the use of the Wilcoxon scores. The use of a particular nonparametric model ...
Comparación entre dos métodos de reducción de dimensionalidad en series de tiempo : Comparison between Two Dimensionality Reduction Methods in Time Series
Two methods of dimensionality reduction of multivariate stationary time series are analyzed: Peña-Box’s methodology in the time domain and Brillinger’s methodology in the frequency domain. Two failures of Peña-Box’s ...
Morphological description and clinical implications of myocardial bridges: an anatomical study in Colombians
Background: Myocardial bridges represent a hotly debated research topic. Myocardial bridges are considered to be a vascular heart variation due to its intermittent or enduring reducing of the arterial lumen, with a possible ...
Effect of potential shape on the density of the impurity states in nanotube
We analyze the effect of the potential shape on the ground state energy of the off-axis neutral donor in GaAs/Ga1−xAlxAs cylindrical nanotube in the presence of the uniform magnetic field applied along the symmetry axis. ...
