Particle Swarm Hybridized with Differential Evolution: Black-Box Optimization Benchmarking for Noisy Functions
(ACM Digital Library, 2009)
In this work we evaluate a Particle Swarm Optimizer hy- bridized with Di®erential Evolution and apply it to the Black- Box Optimization Benchmarking for noisy functions (BBOB 2009). We have performed the complete procedure ...

Search for E(5) symmetry in nuclei: The Ru isotopes
(American Physical Society, 2002-01-01)
We carry out an interacting boson model study of the Ru isotopes using a U(5)-SO(6) transitional Hamiltonian with fixed parameters, where the variation is due only to the change in boson number N. Transitional behavior ...

Homogenization of non-uniformly bounded periodic diffusion energies in dimension two
(IOP Publishing, 2009)
This paper deals with the homogenization of two-dimensional oscillating convex functionals, the densities of which are equicoercive but not uniformly bounded from above. Using a uniform-convergence result for the minimizers, ...

On the Specification of Non-functional Properties of Systems by Observation
(Springer, 2009)
Domain specific languages play a cornerstone role in Model-Driven Engineering (MDE) for representing models and metamodels. So far, most of the MDE community efforts have focused on the specification of the functional ...

The S-phase checkpoint is required to respond to R-loops accumulated in THO mutants
(American Society for Microbiology, 2009)
Cotranscriptional R-loops are formed in yeast mutants of the THO complex, which functions at the interface between transcription and mRNA export. Despite the relevance of R-loops in transcription-associated recombination, the ...

Experimental verification of extraordinary transmission without surface plasmons
(American Institute of Physics, 2009)
This letter provides an experimental demonstration of extraordinary transmission in a closed waveguide system loaded with an electrically small diaphragm. This is a situation where the standard surface plasmon polariton ...

Solitons for the cubic-quintic nonlinear Schrödinger equation with time and space modulated coefficients
(2009)
In this paper, we construct, by means of similarity transformations, explicit solutions to the cubic–quintic nonlinear Schrödinger equation with potentials and nonlinearities depending on both time and spatial coordinates. ...

Online motions recognition method using mobile phone accelerometer
(Universidad de Sevilla, 2009-06)
Accelerometers can obtain data about the movements of sorne person. Ihe continued study of this information can help to a doctor to establish a correct diagnosis or a rehabilitation plan for a person with mobility problems. ...

A test for the Riemann hypotesis
(Adam Mickiewicz University, 2008-09)
We prove that the Riemann Hypothesis holds if and only if I = Z +∞ 1 ˘ Π(x) − Li(x) ¯2 x −2 dx < +∞ with I = J, where J is some definite, computable real number (1.266 < J < 1.273). This provides us with a numerical test ...

Experimental Characterization of IdleTones in Second-Order Bandpass ΣΔ Modulators
(2000)
This paper analyses the tonal behaviour of the quantization noise in second-order bandpass ΣΔ modulators. The analysis performed for lowpass modulators is extended to the bandpass case. As a result, closed form expressions ...
