4. Simple but accurate periodic solutions for the nonlinear pendulum equation
Abstract Despite its elementary structure, the simple pendulum oscillations are described by a nonlinear differential equation whose exact solution for the angular displacement from vertical as a function of time cannot be expressed in terms of an elementary function, so either a numerical treatment or some analytical approximation is ultimately demanded. Su

5. Comprobación de la uniformidad de resultados de un equipo de ensayos simultáneos de termofluencia
ABSTRACT The phenomenon of creep occurs in materials that operate under high temperatures and mechanical stresses, causing changes in their structures; such changes are evidenced by a progressive loss of mechanical strength. The characterization of this phenomenon should be performed with appropriate test machines, which are usually dependent on expensive te

8. ILITIA: telehealth architecture for high-risk gestation classification
Abstract Introduction According to the World Health Organization, about 9.2% of the 28 million newborns worldwide are stillborn. Besides, about 358,000 women died due to complications related to pregnancy in 2015. Part of these deaths could have been avoided with improving prenatal care agility to recognize problems during pregnancy. Based on that, many eff

11. An Improved Method for Acquisition of the Parameters of Jiles-Atherton Hysteresis Scalar Model Using Integral Calculus
Abstract An accurate modeling of materials is essential to obtain reliable results in fields calculation. The Jiles-Atherton approach is widely used for modeling the magnetic hysteresis and depends on its set of five parameters to properly represent material. In this article is proposed an original methodology for obtaining this set of parameters avoiding th
