Image quality evaluation of chest for computed radiography
(2013-04-16)
The daily-to-day of medical practice is marked by a constant search for an accurate diagnosis and therapeutic assessment. For this purpose the doctor serves up a wide variety of imaging techniques, however, the methods ...
Modulation of Functional Features in Electron Transferring Metalloproteins
(Centro de Estudios sobre Ciencia, Desarrollo y Educación Superior, 2020-03)
Electron transferring metalloproteins are typically implicated in shuttling electrons between energy transduction chains membrane complexes, such as in (aerobic and anaerobic) respiration and photosynthesis, among other ...
Identification of fractional-order transfer functions using exponentially modulated signals with arbitrary excitation waveforms
(2020-08-01)
This paper proposes a new identification method based on an exponential modulation scheme for the determination of the coefficients and exponents of a fractional-order transfer function. The proposed approach has a broader ...
Wavefront analysis and modulation transfer function of three multifocal intraocular lenses
(ALL INDIA OPHTHALMOLOGICAL SOC, 2010)
Purpose: To evaluate wavefront performance and modulation transfer function (MTF) in the human eye aft er the implantation of diffractive or refractive multifocal intraocular lenses (IOLs). Materials and Methods: This was ...
A contralateral eye study comparing apodized diffrative and full diffrative lenses: wavefront analysis and distance and near uncorrected visual acuity
(Faculdade de Medicina / USP, 2009)
PURPOSE: To evaluate intraindividual visual acuity, wavefront errors and modulation transfer functions in patients implanted with two diffractive multifocal intraocular lenses. METHODS: This prospective study examined 40 ...

Micro-inverter for integrated grid-tie PV module using resonant controller
(2012-12-11)
Two-stage isolated converters for photovoltaic (PV) applications commonly employ a high-frequency transformer on the DC-DC side, submitting the DC-AC inverter switches to high voltages and forcing the use of IGBTs instead ...
