Teaching general concepts about sensors and transfer functions with a voltage divider
(2011)
This work proposes the use of a simple voltage divider circuit composed by one potentiometer and one resistor to simulate the behavior of the electrical output signal of linear and nonlinear sensors. It is a low cost way ...
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 ...
The relevance of market prices for the design of transfer programs in response to food insecurity
(Elsevier B.V., 2017-11)
This paper focuses on the use of market prices as discriminatory factors for the selection of strategies in response to conditions of food insecurity according to the comparative efficiency of different strategies. A ...
High-Pass Filter Characteristics of the Baroreflex - A Comparison of Frequency Domain and Pharmacological Methods
(Public Library Of Science, 2013-11)
Pharmacological methods to assess baroreflex sensitivity evoke supra-physiological blood pressure changes whereas computational methods use spontaneous fluctuations of blood pressure. The relationships among the different ...
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 ...
Laterally transferred genomic islands in Xanthomonadales related to pathogenicity and primary metabolism
(BLACKWELL PUBLISHING, 2008)
Lateral gene transfer (LGT) is considered as one of the drivers in bacterial genome evolution, usually associated with increased fitness and/or changes in behavior, especially if one considers pathogenic vs. non-pathogenic ...
Piezoelectric mirror shifter transfer function measurement, modelling, and analysis using feedback based synthetic-heterodyne Michelson interferometry
(2020-12-15)
Laser vibrometry has many applications in non-contact dynamic displacement and vibration measurement. A test beam reflected from a target and a reference beam are combined and detected by a photodiode; the photodetected ...
Using a newly developed chironomid transfer function for reconstructing mean annual air temperature at Lake Potrok Aike, Patagonia, Argentina
(Elsevier, 2013-01)
In the Southern Hemisphere, the lack of quantitative temperature records hampers the understanding of climate change since the Last Glaciation and refrains the comparison with the Northern Hemisphere records. To provide ...
