Stable computations by discrete mollification
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2004)
The discrete mollification method is a data smoothing procedure, based on convolution, that is appropriate for the stabilization of explicit schemes for the numerical solution of partial differential equations and the ...
Retrofitting do controle e implementação do quarto e quinto eixos em uma fresadora CNC didática de pequeno porte
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrotécnica, 2013-12-03)
This project proposes the development and implementation of CNC mechanical axis control of the fourth and fifth on a three-axis CNC milling machine. From all the rotary axis, it has been used the fourth axis of the milling ...
A low-voltage triode-MOSFET four-quadrant multiplier with optimized current-efficiency
(2001-01-01)
A low-voltage, low-power four-quadrant analog multiplier with optimized current-efficiency is presented. Its core corresponds to a pseudodifferential cascode, gain-boosting triode-transconductor. According to a low-voltage ...
