Fianoniella stenognatha sp. n. from the Columbretes Islands (Castellón, Spain) is described and illustrated. The new species is distinguished by its longer and narrower mandibles with parallel or divergent rims in the apical half, wider clypeus, hind ocelli more separated…

We propose a new algorithm to obtain the color matching functions of any digital camera, with correct weights and white balance, from the relative scaling of their complete (3-D) spectral sensitivities obtained from real spectroradiometric data. Thanks to this algorithm,…

This paper analyzes the efforts made by the Telefonica Group (the main Spanish firm in the telecommunications sector) to evolve from a bureaucratic culture to another oriented towards total quality and the customer. The need for this change came as…

The precipitation of gypsum during the intrusion of seawater in a coastal aquifer is shown to be a possible cause of the decrease of the sulphate concentration with respect to the conservative freshwater / seawater mixing observed in many field…

Prediction capacity of three main shoot population dynamics methods (age structure, net shoot recruitment per plagiotropic rhizome and shoot census) have been tested for a period of four years (2002–2006) on a Posidonia oceanica meadow. Accuracy of each method was…

Technological innovation requires a technical preparation in material, financial and human resources. However, without a clear corporate culture, the technical side of technological innovation will hardly develop in a satisfactory manner.
In this light, we analyze the origin of a…

The analytical approximate technique developed by Wu et al. for conservative oscillators with odd nonlinearity is used to construct approximate frequency-amplitude relations and periodic solutions to the relativistic oscillator. By combining Newton's method with the method of harmonic balance, analytical…

We study stability properties of a proximal point algorithm for solving the inclusion 0 ∈ T (x) when T
is a set-valued mapping that is not necessarily monotone. More precisely we show that the convergence of
our algorithm is uniform,…

In this work we present a reactive autonomous robot navigation system based only on omnidirectional vision. It does not rely on any prior knowledge about the environment apart from assuming a structured one, like indoor corridors or outdoor avenues. The…

We document variation among 13 populations of distinct species of the lizard genus Xenosaurus in four key reproductive traits: minimum size at maturity, litter size, size at birth, and relative clutch mass (RCM). Despite a common flattened morphology, considerable variation…
