This paper describes the use of artificial lights (Super Bright LEDs) for crop Hydroponics. To compare the growth of plants grown in natural light. The experiments are carried out in a closed dark enclosure, the control of the lights (LEDs) are ON for 16 hours a day. The Temperature was maintained at less than or equal to 30oC using an air pump cycling on and off, the run time on being 30 minut...

Studies of wild populations have provided important insights into the effects of artificial light at night on organisms, populations and ecosystems. However, in most studies the exact amount of light at night individuals are exposed to remains unknown. Individuals can potentially control their nighttime light exposure by seeking dark spots within illuminated areas. This uncertainty makes it dif...

This paper investigates the underwater optical image restoration method under background of target detection based on vision in AUVs. The light source used for AUV is different when operates depths. natural shallow water and artificial deep water. these two conditions. Aiming at problem blurring images, traditional scattering model can obtain satisfactory performance However, it cannot same res...

Abstract Artificial light at night (ALAN) and its associated biological impacts have regularly been characterized as predominantly urban issues. Although far from trivial, this would imply that these only affect ecosystems are already heavily modified by humans relatively limited in their spatial extent, least compared with some key anthropogenic pressures on the environment attract much more s...
