Interface electronics for an RF resonance-based displacement sensor
(IOP Publishing LTD, 2013)
We propose, design, and test an electronic interface for a new standalone, affordable and compact displacement transducer based on resonant cavities. The operation of the interface establishes a self-resonance in the ...
Defects structure characterization of NiMnGa alloys by PALS
(IOP Publishing, 2013)
We have studied the behaviour of defects in off-stoichiometric Ni-Mn-Ga ferromagnetic shape memory alloys by means of positron lifetime spectroscopy. The measurements presented in this work have been performed in six ternary ...
Query-by-Example Spoken Term Detection ALBAYZIN 2012 evaluation: overview, systems, results, and discussion
(Springer, 2013-09)
Query-by-Example Spoken Term Detection (QbE STD) aims at retrieving data from a speech data repository given an acoustic query containing the term of interest as input. Nowadays, it has been receiving much interest due to ...
Exchange biased FeNi/FeMn bilayers with coercivity and switching field enhanced by FeMn surface oxidation
(AIP Publishing, 2013-09)
FeNi/FeMn bilayers were grown in a magnetic field and subjected to heat treatments at temperatures of 50 to 350 degrees C in vacuum or in a gas mixture containing oxygen. In the as-deposited state, the hysteresis loop of ...
Some Results on Fixed and Best Proximity Points of Precyclic Self-Mappings
(Hindawi Publishing Corporation, 2013)
This paper is devoted to investigating the limit properties of distances and the existence and uniqueness of fixed points, best proximity points and existence, and uniqueness of limit cycles, to which the iterated sequences ...
On Bounded Strictly Positive Operators of Closed Range and Some Applications to Asymptotic Hyperstability of Dynamic Systems
(Hindawi, 2013)
The problem discussed is the stability of two input-output feedforward and feedback relations, under an integral-type constraint defining an admissible class of feedback controllers. Sufficiency-type conditions are given ...
Some Results on Fixed and Best Proximity Points of Multivalued
(Hindawi Publishing Corporation, 2013)
This paper is devoted to investigate the fixed points and best proximity points of multivalued cyclic self-mappings on a set of subsets of complete metric spaces endowed with a partial order under a generalized contractive ...
Fixed Points of Closed and Compact Composite Sequences of Operators and Projectors in a Class of Banach Spaces
(Hindawi Publishing Corporation, 2013)
Some results on fixed points related to the contractive compositions of bounded operators in a class of complete metric spaces which can be also considered as Banach's spaces are discussed through the paper. The class of ...
On Best Proximity Point Theorems and Fixed Point Theorems for p-Cyclic Hybrid Self-Mappings in Banach Spaces
(Hindawi Publishing Corporation, 2013)
This paper relies on the study of fixed points and best proximity points of a class of so-called generalized point-dependent (K-Lambda)hybrid p-cyclic self-mappings relative to a Bregman distance Df, associated with a ...
Asymptotic Hyperstability of a Class of Linear Systems under Impulsive Controls Subject to an Integral Popovian Constraint
(Hindawi Publishing Corporation, 2013)
This paper is focused on the study of the important property of the asymptotic hyperstability of a class of continuous-time dynamic systems. The presence of a parallel connection of a strictly stable subsystem to an ...
