Explicit models for perverse sheaves
(European Mathematical Society, 2003)
We consider categories of generalized perverse sheaves, with relaxed constructibility conditions, by means of the process of gluing t-structures and we exhibit explicit abelian categories defined in terms of standard sheaves ...

Exact procedures for solving the discrete ordered median problem
(Elsevier, 2006-11)
The Discrete Ordered Median Problem (DOMP) generalizes classical discrete location problems, such as the N-median, N-center and Uncapacitated Facility Location problems. It was introduced by Nickel [S. Nickel. Discrete ...

Rotenone selectively occludes sensitivity to hypoxia in rat carotid body glomus cells
(Wiley-Blackwell Publishing Ltd., 2003)
Carotid body glomus cells release transmitters in response to hypoxia due to the increase of excitability resulting from inhibition of O2 -regulated K+ channels. However, the mechanisms involved in the detection of changes ...

Complexity Classes in Cellular Computing with Membranes
(2003)
In this paper we introduce the complexity class PMC∗ F of all decision problems solvable in polynomial time by a family of P systems belonging to a prefixed class of recognizer membrane systems, F.

Towards developing generic solutions with aspects
(2004)
Software industry has to face up to continuous and fast changes of technology as well as varying customer’s requirements. In order to adapt software for these new platforms and technologies at a minimum cost some proposals ...

A Precise Electrical Disturbance Generator for Neural Network Training with Real Level Output
(Springer, 2007)
Power Quality is defined as the study of the quality of electric power lines. The detection and classification of the different disturbances which cause power quality problems is a difficult task which requires a high ...

Normal-mode linear analysis and initial conditions of capillary jets
(Cambridge University Press, 2008-04-25)
The normal-mode linear analysis of an axisymmetric infinite capillary jet is generalized to account for arbitrary initial conditions. An exhaustive study of the dispersion relation reveals the parametric behaviour of all ...

A model for two coupled turbulent fluids. Part II: numerical analysis of a spectral discretization
(Society for Industrial and Applied Mathematics, 2002)
We consider a system of equations that models the stationary flow of two immiscible turbulentfluids on adjacentsubdomains. The equations are coupled by nonlinear boundary conditions on the interface which is here a fixed ...

N doping of TiO 2(110) Photoemission and density-functional studies
(AIP Publishing, 2006-09)
The electronic properties of N-doped rutile TiO2(110) have been investigated using synchrotron-based photoemission and density-functional calculations. The doping via N+2 ion bombardment leads to the implantation of N atoms ...
