Behaviour of displacement, cast-in-place piles on collapsible soil
(Fourteenth International Conference on Soil Mechanics and Foundation Engineering, Vol 2, 1997-01-01) [Trabalho apresentado em evento]
The paper presents the results of instrumented compression load tests carried out in three uncased cast-in-place piles (pounded piles, called apiloadas in Brazil) which is largely used in interior part of the state of São ...
DISAGGREGATABILITY OF INDURATED SOILS IN SOUTHEASTERN BRAZIL
(Geotechnical Engineering of Hard Soils - Soft Rocks, Vol 1, 1993-01-01) [Trabalho apresentado em evento]
Nonlinear optimization using a modified Hopfield model
(IEEE World Congress on Computational Intelligence, 1998-01-01) [Trabalho apresentado em evento]
Systems based on artificial neural networks have high computational rates due to the use of a massive number of simple processing elements. Neural networks with feedback connections provide a computing model capable of ...
The asynchronous motor one-dimensional analysis
(1997 IEEE International Electric Machines and Drives Conference Record, 1997-01-01) [Trabalho apresentado em evento]
An application of the linear machine one-dimensional analysis method to the modeling of a conventional asynchronous induction motor, considered as a particular case of linear and sectorial machines, is described. A ...
New approach of induction machine drive using an adaptive digital PID controller with gain planning based on artificial neural networks
(Proceedings of the American Control Conference, 1999-12-01) [Trabalho apresentado em evento]
The present work introduces a new strategy of induction machines speed adjustment using an adaptive PID (Proportional Integral Derivative) digital controller with gain planning based on the artificial neural networks. This ...
Harmonics filtering and detection of disturbances using wavelets
(IEEE International Symposium on Industrial Electronics, 1999-12-01) [Trabalho apresentado em evento]
Traditional mathematical tools, like Fourier Analysis, have proven to be efficient when analyzing steady-state distortions; however, the growing utilization of electronically controlled loads and the generation of a new ...
