The "other" cities: urban planning and architecture for tourism: the case of the Spanish Mediterranean (1945-1975)

There we analyce the first touristic nucleus arouse in the Spanish Mediterranean coast between World War II and the Petroleum Crisis (1945-75). Special attention is payed to the characteristics of these new villages: the relation of their urban frame with nature -original or artificial- and the lack of industry. We make a distintion of three types: cluster nucleus (La Manga and El Saler), tridimentional urbanism (Playa de San Juan y Urbanova) and extreme typologies (Campoamor and Benidorm). With them the cities for vacations are discovered, mainly for second home purpouse (vacation home/holiday home). The panorama after the current crisis is a lineal chain of small urban settlements on the coast. Finally, Finally, we can see how these "secondary cities" without industry and specialized in leisure, are developing to our days until become new cities of services, doubling the existing ones; now they are "the other cities".

Spectral BRDF-based determination of proper measurement geometries to characterize color shift of special effect coatings

A reduced set of measurement geometries allows the spectral reflectance of special effect coatings to be predicted for any other geometry. A physical model based on flake-related parameters has been used to determine nonredundant measurement geometries for the complete description of the spectral bidirectional reflectance distribution function (BRDF). The analysis of experimental spectral BRDF was carried out by means of principal component analysis. From this analysis, a set of nine measurement geometries was proposed to characterize special effect coatings. It was shown that, for two different special effect coatings, these geometries provide a good prediction of their complete color shift.

Global color estimation of special-effect coatings from measurements by commercially available portable multiangle spectrophotometers

Colors of special-effect coatings have strong dependence on illumination/viewing geometry and an appealing appearance. An open question is to ask about the minimum number of measurement geometries required to completely characterize their observed color shift. A recently published principal components analysis (PCA)-based procedure to estimate the color of special-effect coatings at any geometry from measurements at a reduced set of geometries was tested in this work by using the measurement geometries of commercial portable multiangle spectrophotometers X-Rite MA98, Datacolor FX10, and BYK-mac as reduced sets. The performance of the proposed PCA procedure for the color-shift estimation for these commercial geometries has been examined for 15 special-effect coatings. Our results suggest that for rendering the color appearance of 3D objects covered with special-effect coatings, the color accuracy obtained with this procedure may be sufficient. This is the case especially if geometries of X-Rite MA98 or Datacolor FX10 are used.
