During shortcut biological nitrogen removal in a polluted river, total nitrogen, ammonia nitrogen and nitrite nitrogen were quantified by near infrared spectroscopy and the synergy interval partial least squares (siPLS) algorithm. Spectral data of 138 water samples were obtained with a near infrared spectrometer. In addition, the real values of total nitrogen, ammonia nitrogen and nitrite nitrogen...
Carbon productivity is a special indicator that coordinates economic development and climate resource protection. Similar to carbon productivity, electricity carbon productivity (ECP) is defined and researched in our paper since it is an effective way for China’s power industry to realize the low-carbon development path. In this work we have applied the multi-dimensional decomposition method to ECP...
