Application of gold complexes in the development of sensors for volatile organic compounds
(World Gold Council, 2007)
Artículo / Artikulua,
Two different kinds of sensors have been developed by using the same kind of vapochromic complexes. The vapochromic materials [Au2Ag2(C6F5)(4)L-2](n) have different colours depending on the ligand L. These materials change, ...
Modelling fibrillation potentials: analysis of time parameters in the muscle intracellular action potential
(IEEE, 2007)
Artículo / Artikulua,
A single fibre action potential (SFAP) can be
modelled as the convolution of a biolectrical source and a filter
impulse response. In the Dimitrov-Dimitrova (D-D)
convolutional model, the first temporal ...
A new muscle architecture model with non-uniform distribution of muscle fiber types
(World Academy of Science, Engineering and Technology, 2007)
Artículo / Artikulua,
According to previous studies, some muscles present
a non-homogeneous spatial distribution of its muscle fiber types
and motor unit types. However, available muscle models only
deal with muscles with homogeneous ...
Signal processing in ocean bottom seismographs for refraction seismology
(IEEE, 2006)
Artículo / Artikulua,
This paper presents some experimental results on the application of signal processing techniques to underwater seismic signals. The novelty of this paper stems from the fact that it is the first paper, to the best of the ...
Motor unit action potential duration, II: a new automatic measurement method based on the wavelet transform
(Lippincott, Williams & Wilkins, 2007)
Artículo / Artikulua,
To present and evaluate a new algorithm, based on the
wavelet transform, for the automatic measurement of motor unit
action potential (MUAP) duration. A total of 240 MUAPs were
studied. The waveform of each MUAP was ...
Independent component analysis as a tool to eliminate artifacts in EEG. A quantitative study
(Lippincott, Williams & Wilkins, 2003)
Artículo / Artikulua,
Independent component analysis (ICA) is a novel technique that calculates
independent components from mixed signals. A hypothetical clinical application is to
remove artifacts in EEG. The goal of this study was to apply ...
Motor unit action potential duration, I: variability of manual and automatic measurements
(Lippincott, Williams & Wilkins, 2007)
Artículo / Artikulua,
To analyze the variability in manual measurements of
motor unit action potential (MUAP) duration and to evaluate the
effectiveness of well-known algorithms for automatic measurement.
Two electromyographists carried out ...
Ultra-wideband metamaterial filter based on electroinductive-wave coupling between microstrips
(EMW Publishing, 2009)
Artículo / Artikulua,
In this work, we analyse the frequency response of
microstrip lines coupled by complementary split ring resonators
(CSRRs) etched on the ground plane supporting electroinductive
waves (EIWs). The single-particle ...
Fiber optic multiple-wavelength filter based on one dimensional photonic bandgap structures with defects
(IEEE, 2004)
Artículo / Artikulua,
In this paper, a theoretical analysis is given of an
optical fiber multiple-wavelength tunable filter based on a onedimensional
(1-D) photonic bandgap (PBG) structure with four
defects. To understand the positioning of ...
Influence in cladding mode distribution of overlay deposition on long-period fiber gratings
(Optical Society of America, 2006)
Artículo / Artikulua,
A thin overlay of higher refractive index than that of the cladding of a long-period fiber grating induces in
cladding modes strong variations in effective index, mode profile, cross-coupling coefficient with the core ...
