A computer system representing user preferences in an N-dimensional preference topography and making recommendations based on such topography. The wear resistant coating is applied to at least the tire bead flange of the vehicle wheel but may be applied to any area of the wheel. The refractive index change layer includes a plurality of high refractive index portions and low refractive index portions having a refractive index that is lower than the refractive index of the high refractive index portions. When the user travels and wishes to enable the electronic processing device, the GPS card and antenna receive and process the device’s current location. The method comprises a step of irradiating the coating by an electromagnetic radiation at a power P and within a defined spectrum, wherein the defined spectrum corresponds to an absorption peak of the volatile organic solvent. The semiconductor structures including nano-structures or fabricated using nano-structures.
