Planning Fixed to Flexgrid Gradual Migration: Drivers and Open Issues

Flexgrid technology has recently been presented as the most promising option for upgrading the currently operating fixed grid optical networks and extending their capacity to be able to deal with the massive traffic volumes forecast for the next decade. Although the current traffic is successfully supported on fixed grid networks, flexgrid technology brings features that are not offered by the fix

Clustering ECG complexes using Hermite functions and self-organizing maps

An integrated method for clustering of QRS complexes is presented which includes basis function representation and self-organizing neural networks (NN's). Each QRS complex is decomposed into Hermite basis functions and the resulting coefficients and width parameter are used to represent the complex. By means of this representation, unsupervised self-organizing NNs are employed to cluster the data

Genetic structure and eco-geographical adaptation of garlic landraces (Allium sativum L.) in Iran

In this study we present the genetic analysis of freshly collected garlic landraces (Allium sativum L.) along an eco-geographical transect from northeastern to western Iran covering seven different provinces using ISSR and RAPD markers. A total of 52 polymorphic loci were detected among 31 landrace populations. The percentage of polymorphic bands, the mean effective number of alleles, and the mean

The effect of foam surface properties on postural stability assessment while standing.

A common assessment of postural control often involves subjects standing on a compliant surface, such as a foam block, to make balance tests more challenging. However, the physical properties of the foam block used by different researchers can vary considerably. The objective of this study was to provide an initial approach for investigating whether two of the foam properties, i.e. density and ela
