A stopband filter design using a 1-D non-periodic defected ground structure
(Wiley, 2003)
Artículo / Artikulua,
The one-dimensional (1-D) defected ground structure is used to control the cutoff frequency characteristic. In this paper three non-periodic filters are built, in order to show the versatility of the DGS. Five unit cells ...
Ultra-wide band corrugated profiled horn antenna design
(IEEE, 2002)
Artículo / Artikulua,
Nowadays, an increasing number of applications need stable radiation patterns
with low sidelobes and low crosspolar levels in a very wide bandwidth. Gaussian Profiled
Horn Antennas (GPHA’s) have demonstrated its feasibility ...
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 ...
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 ...
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 ...
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 ...
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 ...
Strategies for fabrication of hydrogen peroxide sensors based on electrostatic self-assembly (ESA) method
(Elsevier, 2004)
Artículo / Artikulua,
An optical fiber sensor has been fabricated for detection of 5 M–0.1mM concentrations of hydrogen peroxide with a linear response. The
deposition method used is electrostatic self-assembly (ESA) of polymer cationic and ...
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 ...
Spectral evolution with incremental nanocoating of long period fiber gratings
(Optical Society of America, 2006)
Artículo / Artikulua,
The incremental deposition of a thin overlay on the cladding of a
long-period fiber grating (LPFG) induces important resonance wavelength
shifts in the transmission spectrum. The phenomenon is proved theoretically
with ...
