(1998)
New high resolution spectroscopic and medium resolution spectropolarimetric data, complemented with optical broad and narrow band imaging, of the B[e] star HD 87643 are presented. The spectrum of HD 87643 exhibits the ...
A dual GTO current-source converter topology with sinusoidal inputs for high-power applications
(1998)
A dual gate-turn-off thyristor current-source converter topology with sinusoidal inputs is proposed for high-power applications. The sinusoidal input current is realized by using pulsewidth modulation techniques to eliminate ...

Evolutionary tuning method for automatic impedance matching in communication systems
(Institute of Electrical and Electronics Engineers (IEEE), 1998)
An evolutionary tuning method for automatic impedance matching in radio communication systems is developed based on genetic algorithms (GA). A detailed tuning procedure is presented and a software package has been developed. ...
A Connectionist account of Spanish determiner production
(Springer Nature, 1998)
A Connectionist Network that models the production of simple phonologically coded Spanish Noun Phrases is described. The training data uses type/token frequencies taken directly from a Spanish child's linguistic environment. ...
Fully-balanced structures of continuous-time MLF OTA-C filters
(Institute of Electrical and Electronics Engineers (IEEE), 1998)
This paper presents general fully balanced structures of continuous-time OTA-C filters based on multiple loop feedback (MLF) configurations. Both simple all pole and complex arbitrary zero fully balanced implementations ...
