This study examines the relevance of environmental management as a source of competitive advantage for hotels. The relationship between the environmental proactivity of hotels located in the province of Alicante (Spain) and their economic performance levels was studied, and three…

The aim of this study is to develop a color visualization system for multispectral images in the near-infrared region (NIR, 800–1000 nm). Samples with the same color or appearance in the visible region, which are therefore indistinguishable to the human

An approximation scheme to obtain the period for large amplitude oscillations of a simple pendulum is analysed and discussed. The analytical approximate formula for the period is the same as that suggested by Hite (2005 Phys. Teach. 43 290), but…

There is considerable interest in real-world formation-maintenance tasks, where robots move together while maintaining a geometric shape. This interest is motivated by promise of robustly and efficiently moving multiple robots along a path, guided by a human operator. This paper…

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 dynamically shifted oscillator. This nonlinear oscillator is described by an equation of motion…

Fecal samples from the Siberian tiger (Panthera tigris altaica)
and the Amur cat (Felis bengalensis euptilurus) from Far Eastern
Russia, were examined for parasites. A natural sedimentation methodology
was used and a complete examination of all the sediment was
performed.…

We present a systematic algorithm capable of searching for optimal colors for any lightness L* (between 0 and
100), any illuminant (D65, F2, F7, F11, etc.), and any light source reported by CIE. Color solids are graphed in
some color…

Bleached holograms are one of the most interesting techniques used to produce phase holograms of high quality on photographic emulsions. Of particular interest is the method of fixation-free rehalogenating bleaching. In this paper we will study the influence of the…

Evaluations are provided of 21 descriptors of Posidonia oceanica meadows along the coast of Valencia, Spain, with a view to using these in implementing the European Water Framework Directive (WFD). The descriptors selected are known to respond to a variety…

This paper introduces the development of an infrastructure to study highly complex systems of Ambient Intelligence (AmI) which involve a large number of users. The key ideas about the development of a multi-agent based simulation (MABS) for such purposes, Ubik,…
