Synthesis of Optical Filters Using Sagnac Interferometer in Ring Resonator
(11/12/2007)
We propose a new synthesis method for the implementation of infinite impulse response filters, using a Sagnac interferometer within a ring resonator. This structure permits the synthesis of second-order optical functions ...
Clinically low-risk prostate cancer: evaluation with transrectal doppler ultrasound and functional magnetic resonance imaging
(Faculdade de Medicina / USP, 2011)
OBJECTIVES: To evaluate transrectal ultrasound, amplitude Doppler ultrasound, conventional T2-weighted magnetic resonance imaging, spectroscopy and dynamic contrast-enhanced magnetic resonance imaging in localizing and ...
c ̂-Axis resistivity in graphite-AlCl3 as found by CESR measurements
(Elsevier B.V., 1990-06-01)
We report the absolute values of the c ̂-axis resistivity obtained from conduction electron spin resonance (CESR) experiments at various temperatures for a graphite-AlCl3 stage 2 compound. The agreement with d.c. measurements ...

Impaired reconversion of bone marrow in nuclear magnetic resonance in patients with chronic renal disease
(2021)
BACKGROUND: Anemia is one of the main consequences of Chronic Kidney Disease (CKD), which causes a bone marrow response determined by Magnetic Resonance Imaging. OBJECTIVE: The objective of this study was to identify Bone ...
Micro-inverter for integrated grid-tie photovoltaic module using resonant controller
(Wiley-Blackwell, 2014-05-01)
Two-stage isolated converters for photovoltaic (PV) applications commonly employ a high-frequency transformer (HFT) on the DC-DC side, submitting the DC-AC inverter switches to high voltages and forcing the use of ...

Estudo comparativo dos métodos de ultra-sonografia, tomografia computadorizada e ressonância magnética no estadiamento e invasão das estruturas adjacentes por tumores renais.
(2001-07-01)
BACKGROUND: Ultrasonography (US), Computed Tomography (CT), and Magnetic Resonance imaging (MR) were compared for the staging of renal tumors. The differences between these imaging techniques were also studied for their ...
