A set of N-heteroquinones, deriving from oligoacenes, have been recently proposed as n-type organic semiconductors with high electron mobilities in thin-film transistors. Generally speaking, this class of compounds self-assembles in neighboring π-stacks linked by weak hydrogen bonds. We aim at…

The research presented in this paper approaches the issue of indoor localization using the fuzzy logic framework for modeling and dealing with the uncertainty of the position measurements. Fuzzy logic presents properties that make it suitable tool to represent and…

The main step in the production of carbon nanofilaments is the catalytic nucleation and lengthening of the filament. An undesired parallel step in
the production of carbon nanofilaments is their thickening by pyrolitic carbon vapor deposition consisting in an ordered…

Two styrene–bTwo styrene–butadiene–styrene block rubbers, one with 10wt% calcium carbonate filler (S6C), and one without (S6) were surface treated with UV radiation. The resulting surface modifications and adhesion properties with polyurethane adhesive were studied. The surface modifications produced on these…

Silver halide sensitized gelatin (SHSG) is one of the most promising techniques for the fabrication of transmission holographic optical elements, achieving relatively high sensitivity of photographic material with the low scattering and high light stability of dichromated gelatin. In this…

Numerical calculation of Fresnel patterns through fast Fourier transforms usually requires an extremely large number of samples in order to fulfil the Nyquist sampling condition. In many applications, the cut-off frequency of the system is much below the limit fixed…

This study has pursued to find the efficacy values in the playing micro-situations with or without ball possession present in Water polo and to analyze the relation between these and the condition of winner or loser, among winning teams, among…

The aim of the present work was to compare the cardiorespiratory response of two high level groups of triathletes of different age during a simulation of a cycling-running succession. The two groups, G1 (n=6; age 23.8 ± 5.6 years; weight…

Existen muy pocos estudios sobre la biomecánica de la gimnasia rítmica. El presente estudio analiza
cuatro saltos de una experimentada gimnasta rítmica de alto nivel (competición nacional) de 16 años de
edad, 175 cm de altura y 50 kg de…

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…
