The paper presents time, frequency, and real-time properties of a fractional-order PID controller (FOPID) implemented at STM 32 platform. implementation uses CFE approximation discrete version Grünwald–Letnikov operator (FOBD). For these implementations, experimental step responses Bode frequency were measured. Real-time the approximations are also examined analyzed. Results tests show that use...

INTRODUCTION The present study was carried out from March to May 2008, with the aim of evaluating the effectiveness of different techniques for diagnosing Blastocystis hominis in a sample of the population attended at the Biomedicine Laboratory of Feevale University, Novo Hamburgo, Rio Grande do Sul. METHODS On hundred feces samples from children and adults were evaluated. After collection, t...

Primary amoebic meningoencephalitis (PAM) is a fatal infection in most cases, caused by the amoeba flagellate Naegleria fowleri. This report describes the first cases of PAM in Algeria, in a cow and a ewe from Batna, north-eastern Algeria. The death of both ruminants occurred a week after the first clinical manifestations. The cerebrospinal fluid, after staining with May-Grünwald-Giemsa, showed...

J. Bacteriol. 84:1330-1337. 1962.-Three strains of the atypical pneumonia agent were adapted to grow in continuous cell cultures of human amnion or human embryonic lung, with production of initial in...

This paper proposes a generic FPGA realization of an IP core for fractional-order integration and differentiation based on the Grünwald–Letnikov approximation. All dependent terms are approximated to simpler relations using curve fitting enable efficient hardware realization. Compared previous works, proposed design introduces enhancements in range covering both differentiation. An error analys...
