The road sign recognition (RSR) system is used to complete two tasks: localizing the traffic in an image and then classifying it according features. Some of applications such are incorporated into Advanced Driver Assistance System (ADAS) autonomous vehicles. However, accuracy model decreases when changes lighting or weather occurs, lack training samples taken rainy condition causes be sub-optim...

The aim of this study was to investigate the adaptation of the cyanobacterium Fischerella sp. ISC 107to combined effects of carbon dioxide concentration, acidic and alkalinity. Axenic strain was incubated in BG0-11 medium. Carbon dioxide treatments were limited and relatively non-limited. Acidic (pH 5), neutral (pH7), and alkaline (pH 9) conditions were employed in each treatment. Survival, gro...

We analyze measures of the azimuthal asymmetry, in particular the participant harmonic moments, ε∗, in a variety of Glauber-like models for the early stage of collisions at RHIC. Quantitative comparisons indicate substantial model dependence for ε∗, reflecting different effective number of sources, while the dependence of the scaled standard deviation σ(ε∗)/ε∗ on the particular Glauber model is...
