The G619A Aa-nat gene polymorphism does not contribute to sleep time variation in the brazilian population
(Springer, 2007-07-01)
Genes involved in melatonin synthesis, such as Aa-nat, may be important for our understanding of diurnal preference and circadian rhythm disturbances in humans. in Japan, Hohjoh et al. reported increased allelic frequencies ...
Sensoreamento e controle de conversores estáticos com a utilização de FPGA
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2016-12-22)
The work introduced next looks to implement voltage and current measures on static power converters and implement a control law using VHDL and implementing it using FPGA. For case study, it was considered a elevator converter ...
PC-DSPs-based signal processing and control system for MST radars
(Instituto Geofísico del Perú, 1996)
This paper describes a signal processing and control system, designed and built for the Peruvian MST radar installed in the "Machu-Picchu" Scientific Station, Antarctica (62 º05'5 S, 58º28' W). System architecture, based ...
Embedded DSP-Based Compact Fuzzy System and Its Application for Induction-Motor V/f Speed Control
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
This paper presents a compact embedded fuzzy system for three-phase induction-motor scalar speed control. The control strategy consists in keeping constant the voltage-frequency ratio of the induction-motor supply source. ...
