Pilot tone aided measurements to extend the bandwidth of radio frequency applications
(Elsevier B.V., 2016)
A technique to extend the effective measurement bandwidth of a non-coherent vector receiver is presented. This bandwidth extension technique relies on the use of a pilot signal (known a priori), which is added on the signal ...
Multivariate control charts based on net analyte signal (NAS) and Raman spectroscopy for quality control of carbamazepine
(Elsevier Science BvAmsterdamHolanda, 2011)
Determination and Validation of Nimesulide in Pharmaceutical Formulation by Near Infrared Spectroscopy

Analytical model of signal generation for radio over fiber systems
(Universidad Nacional de Colombia Sede Medellín, 2014-12-15)
This paper presents an analytical model that describes the elements involved in the signal generation feasible to be used in radio over fiber systems for the transport of information. In these systems, the radio frequency ...
Utilization of Fourier transform filter for noise minimization in analytical signals.

Validation of models of multivariate calibration: An application in the determination of polymorphic purity of carbamazepine by near infrared spectroscopy.
(Soc Brasileira QuimicaSao PauloBrasil, 2004)
Multi-energy calibration applied to atomic spectrometry
(2017-08-22)
Multi-energy calibration (MEC) is a novel strategy that explores the capacity of several analytes of generating analytical signals at many different wavelengths (transition energies). Contrasting with traditional methods, ...
Analytical relation between b-value and electromagnetic signals in pre-macroscopic failure of rocks: insights into the microdynamics' physics prior to earthquakes
(2023)
Field measurements in subduction regions have revealed the presence of non-seismic pre-earthquake signals such as electromagnetic or acoustic emission, gas liberation, changes in Earth's surface temperature, changes at the ...
Selective determination of Cr (VI) by on-line solid phase extraction FI-SPE-FAAS using an ion exchanger resin as sorbent: An improvement treatment of the analytical signal
(Elsevier Science, 2017-01)
A flow injection (FI) technique based on an on-line solid phase extraction (SPE) coupled with flame atomic absorption spectroscopy (FAAS) to selectively quantify chromium (VI) in the presence of chromium (III) was developed. ...
