En el documento se presenta una clasificación de diferentes tipos de gestos de la mano por medio de señales mioeléctricas (EMG), las cuales serán procesadas por un filtro tipo Kernel Gaussiano, para su posterior clasificación utilizando del método de Polinomios Anidados. Se tiene como resultados del proceso de clasificación la correcta identificaci...
This paper presents a set of generalized iterative algorithms to find the inverse position kinematics of n-degree-of-freedom kinematic chains with revolute joints. As a first approach, an iterative algorithm is developed using the gradient descent method in Quaternion Algebra to find both the inverse position and velocity kinematics solution in red...
In this work, by reformulating screw theory (generalization of quaternions) in the conformal geometric algebra framework, we address the interpolation, virtual reality, graphics engineering, haptics. We derive intuitive geometric equations to handle surface operations like in kidney surgery. The interpolation can handle the interpolation and dilati...
This work presents a new type of Spike Neural Networks (SNN) developed in the quaternion algebra framework. This new neural structure based on SNN is developed using the quaternion algebra. The training algorithm was extended adjusting the weights according to the quaternion multiplication rule, which allows accurate results with a decreased networ...

... En comparación con las matrices de rotación, son más eficientes y más estables numéricamente. Los cuaterniones sonútiles en aplicaciones de gráficos por computadora, robótica, navegación y mecánica orbital satelital Goldman (2010); Lechuga-Gutiérrez et al. (2018); Yu et al. (2011). Un cuaternión se puede expresar como el conjunto: ...

... Otras aplicaciones tienen que ver con el desarrollo de prótesis de la mano para la representación de movimientos e implantación en pacientes con amputación como en (Villamil and Sanchez, 2018), (Miguel et al., 2016) y (J..Brazeiro et al., 2015). Por otro lado, se cuenta con estudios relacionados con el procesamiento y caracterización de las señales EMG para una posterior manipulación de diferentes dispositivos como en (J..Brazeiro et al., 2015), (Guachamin, 2017) y (Gutierrez et al., 2018). Se han aplicado otras implementaciones para detección de gestos nuevos como en (Chimal, 2017); los cuales son utilizados en algunos dispositivos robóticos. ...
... In this subsection, we show the use of the quadratic Study interpolation algorithm to interpolate geometric entities and to guide the suture of a kidney wound, see [20] for more details about this interpolation. ...
