The lattice of fitting classes which are right extensible by soluble groups
(Universidad Autónoma de Barcelona, Departamento de Matemáticas, 2005)
Artículo / Artikulua,
In this paper we study the set of fitting classes which are right extensible by soluble groups ordered by the inclusion relation. The consideration of the associated lattices gives rise to new fitting classes and it allows ...
Design of low-cost smart accelerometers
(Universitat Politècnica de Catalunya, 2005)
Contribución a congreso / Biltzarrerako ekarpena,
The goal of this project is to design a low-cost smart accelerometer, making use of a piezoelectric
element as basic sensing material, and adding a
mixed-mode conditioning circuit.
Computation of greatest common divisor for the blind deconvolution of transient impulsive signals
(Universitat Politècnica de Catalunya, 2005)
Contribución a congreso / Biltzarrerako ekarpena,
We propose a new blind deconvolution method for transient impulsive signals in a single input
– multiple output (SIMO) system. The method
exploits the data redundancy inherent to SIMO
multichannel systems to obtain an ...
Semicontinuous planar total preorders on non-separable metric spaces
(The Korean Mathematical Society, 2009)
info:eu-repo/semantics/article,
We prove that every non-separable connected metric space
can be endowed with a total preorder that is order-isomorphic to a nonrepresentable
subset of the lexicographic plane and semicontinuous with
respect to the metric topology.
Chaos in the libration motion of an asymmetric non-rigid spacecraft
(2004)
info:eu-repo/semantics/conferenceObject,
We study the libration motion dynamics of an asymmetric spacecraft in circular orbit under the influence of a gravity gradient torque
The Tsirelson space tau (p) has a unique unconditional basis up to permutation for 0 < p < 1
(Hindawi Publishing Corporation, 2009)
Artículo / Artikulua,
We show that the p-convexified Tsirelson space tau((p)) for 0 < p < 1 and all its complemented subspaces with unconditional basis have unique unconditional basis up to permutation. The techniques involved in the proof are ...
On perfectly homogeneous bases in quasi-Banach spaces
(Hindawi Publishing Corporation, 2009)
Artículo / Artikulua,
For 0 < p < infinity the unit vector basis of l(p) has the property of perfect homogeneity: it is equivalent to all its normalized block basic sequences, that is, perfectly homogeneous bases are a special case of symmetric ...
Valoración de la capacidad funcional en el ámbito domiciliario y en la clínica. Nuevas posibilidades de aplicación de la acelerometría para la valoración de la marcha, equilibrio y potencia muscular en personas mayores
(Gobierno de Navarra, 2008)
Artículo / Artikulua,
Dentro de cualquier población de individuos mayores de 65 años, una proporción sustancial (entre el 6% y el 25%) sufre diferentes síntomas del síndrome de fragilidad. A pesar de la complejidad del termino fragilidad y de ...
