Realistic mathematical models are of great importance for studying the optical performance of the human eye. Light propagation algorithms provide robust methods to calculate field distributions inside a homogeneous medium, and thus they can be applied to the study of…

This paper considers the task reallocation problem, where k robots are to be extracted from a coordinated group of N robots in order to perform a new task. The interaction between the team members and the cost associated with this…

The intra- and interspecific variability in the West Palaearctic tibialis-group species of the subgenus Pandasyopthalmus (Diptera: Syrphidae: Paragus) was analysed. Novel immature and molecular characters were studied and the traditionally used adult characters reviewed with the aim of establishing the…

Theodore Motzkin proved, in 1936, that any polyhedral convex set can be expressed as the (Minkowski) sum of a polytope and a polyhedral convex cone. This paper provides five characterizations of the larger class of closed convex sets in finite…

Background: Education is a basic prerequisite for d/Deaf people’s health. Deaf education varies considerably from country to country and we still know very little about the reasons for such variation. Objective: To identify international megatrends that influence the current Deaf…

The authors have developed a simple method to compare the colour gamuts of
different industries (printing, textiles, plastics, etc.) based on representing the reproduced
colours in constant lightness L* and hue hab* planes. This method allows the analysis of those

We examined distribution and breeding success of semi-colonial Montagu’s Harriers (Circus pygargus) in relation to habitat in Castellón province (eastern Spain). Breeding areas used by harriers at a 1-km2 scale were characterised by having intermediate percentages of scrub cover, their…

Purpose – The idea that knowledge management can be a potential source of competitive advantage has gained strength in the last few years. However, a number of business actions are needed to generate an appropriate environment and infrastructure for knowledge…

An easy method to synthesize Pt nanoparticles supported on conductive polymers has been explored. The synthesis was carried out under “soft” conditions, i.e., at low temperatures and without using strong reducing agent. The optimal synthesis conditions have been established. Thus,…

The aim of this paper is to analyse the Spanish verb acostarse, following the theoretical tools established by Geeraerts (1997). From the perspective of Cognitive Semantics, linguistic categories evolve from prototypic to new meanings as a result of metonymic or…
