Mean room surface exitance (MRSE) is a metric proposed to assess lighting quantity within new design methodology focused on ambient and target illumination. This research builds upon findings from previous examining the suitability of MRSE as for assessing illumination brightness levels adequacy offices. An experiment was conducted investigate finding studies that linear relationship existed be...

In this paper, we use the elementary methods and properties of classical Gauss sums to study calculation problems some mean values character special polynomials, obtained several interesting formulae for them. As an application, give a criterion determining that 2 is cubic residue any odd prime p.
