CODYRUN is a software for computational aeraulic and thermal simulation in buildings developed by the Laboratory of Building Physics and Systems (L.P.B.S). Numerical simulation codes of artificial lighting have been introduced to extend the tool capacity. These calculation codes are able to predict the amount of light received by any point of a given working plane and from one or more sources i...

Six of the seven Technical Committees of CIE Division 8 met in Scottsdale, AZ in conjunction with the recent IS&T 10th Color Imaging Conference. In addition, Todd Newman, Director of CIE Division 8, presented a Division 8 update as part of the conference. Therefore, it seems appropriate to make CIE Division 8, Image Technology, the focus of this Standards Update. My appreciation to Todd for all...

We address the problem of finding harmonic colors, this problem has many applications, from fashion to industrial design. The proposed approach enables to evaluate and generate color combinations incrementally. In order to solve this problem we consider that colors follow normal distributions in tone (chroma and lightness) and hue. The proposed approach relies in the CIE standard for representi...

The development of a Microsoft Excel spreadsheet is described, for the accurate calculation of CIE (Commission Internationale de l’Eclairage) 1931 xy chromaticity coordinates and luminance data from visible region absorption spectra recorded in transmission mode. Using firmly established CIE principles, absorbance-wavelength data from visible spectra recorded using a Hewlett Packard 8452A diode...

The knowledge of the luminance coefficient q or of the reduced luminance coefficient r of road surface is an unavoidable requirement for designing road lighting installations able to assure adequate road luminance for visual conditions, energy consumption and traffic safety according to standard requirements. Unfortunately q available data refers to measurements made during the seventies with n...

Haematite and haematite bearing rocks is a common raw material in Palaeolithic. Widespread in nature, it occurrs either in isolated oucrops or in privileged litostratigraphic formations (in Central Europe these are Lower Devonian, Lower Permian, Lower Triassic and Upper Triassic rocks). All must have provoked an interest of Palaeolithic people so we have searched for a fingerprint for all. So f...
