Flexgrid optical networks are attracting huge interest due to their higher spectrum efficiency and flexibility in comparison with traditional wavelength switched optical networks based on the wavelength division multiplexing technology. To properly analyze, design, plan, and operate flexible and elastic networks, efficient methods are required for the(More)
—Elastic flexgrid optical networks (FG-ON) are considered a very promising solution for next-generation optical networks. In this article we focus on lightpath adaptation under variable traffic demands in FG-ON. Specifically, we explore the elastic spectrum allocation (SA) capability of FG-ON and, in this context, we study the effectiveness of three(More)
In this paper we present a framework to define transfer functions from a target distribution provided by the user. A target distribution can reflect the data importance, or highly relevant data value interval, or spatial segmentation. Our approach is based on a communication channel between a set of viewpoints and a set of bins of a volume data set, and it(More)
Obscurances, from which ambient occlusion is a particular case, is a technology that produces natural-looking lighting effects in a faster way than global illumination. Its application in volume visualization is of special interest since it permits us to generate a high quality rendering at a low cost. In this paper, we propose an obscurance-based framework(More)
Various biochemical strategies are followed for the prenatal diagnosis of glutaric aciduria type I (GA I). However, since the description of patients with normal excretion of glutarate and significant residual activity, the difficulties of prenatal biochemical diagnosis are obvious. The characterization of the glutaryl-CoA dehydrogenase (GCDH) gene has(More)
X-linked adrenoleukodystrophy (X-ALD) is a neurodegenerative disorder caused by an impairment in peroxisomal beta-oxidation of very long straight-chain fatty acids (VLCFAs). Six clinical phenotypes have been delineated: childhood cerebral (CCALD), adolescent cerebral (AdolCALD), adult cerebral (ACALD), adrenomyeloneuropathy (AMN), Addison-only (AO), and(More)
In this work it is presented the study and the obtained results when applying elasticity in flexible optical networks using flexgrid technology and with objective to evaluate a future line of work that helps to solve the routing and spectrum allocation within next-generation optical networks. For this project, a set of elasticity schemes is proposed and(More)
BACKGROUND A. baumannii outbreaks are difficult to control because of the relative ease with which this microorganism spreads and persists in hospital settings. Successive papers reported increased resistance in clinical isolates of A. baumannii, currently resistant to most antibiotics. The purpose of this study was to characterize the epidemiological(More)
