Classification of artificial light sources and estimation of Color Rendering Index using RGB sensors, K Nearest Neighbor and Radial Basis Function

Three types of artificial light sources work with electricity: incandescent, fluorescent and LED. These sources require characterization processes to allow selecting the most suitable for the application, to evaluate their capacity or more recently to tune and adjust their replicability using control algorithms. Therefore, it has been necessary to develop indices that represent these capabilities. The Color Rendering Index (CRI) is a measure used to characterize the color reproducibility of a

treatment facilities (MacRae et al. 1991). In certain cases, the oligotrophs were a predominant population, pointing to efficient purification processes in oil refinery wastewaters (Petrovic et al. 1986; Kolarević et al. 2011). However, there is a lack of study on oligotrophic nitrifiers or denitrifiers microbiome in the sewage treatment ecosystem (STE). The STE is composed of three purification crafts, including grille filtration, constructed rapid infiltration (CRI), and an artificial wetland in turn
