A buffer ring is a basic unit for calculating urban land density and nighttime light intensity. The scale effects caused by the differences in the resolution of land use and nighttime light data can be eliminated after calculation. Using Google high-resolution imagery, we define the central ...
Light factors in the study were regulated precisely by LED control system developed by BAAFS. All tested plants were subjected to mixed R (peak at 660 nm) and B (peak at 450 nm) with total PPFD of 200 μmol·m−2·s−1(R:B = 9:1). The light intensity was measured at p...
littorale growth under different temperature and light intensity conditions accompanied with calculation results by model B. Because another evaluation technique was necessary to elucidate the effects between temperature and light intensity on C. littorale growth, the mathematical modeling was examined in ...
Measurements of the intensity (mW) of the LED light source emitting at 660 nm (110 mA CW) were taken with a ph100-si (Gentec-eo, Quebec, Canada) at every centimeter, up to a 10-cm distance away from the light source. This was important to ensure that the proper amount of photons ...
A commercial silver mirror (Thorlabs PF10-03-P01) is used to record the incident light intensity as a reference for reflective spectrum calculation and normalization. For beam bending measurements, the back focal plane (BFP) of the objective lens is imaged to the 100 μm entrance slit of ...
intensity (Supplementary Fig.1a–c). Complete thermal relaxation of CAN back to its dark conformation occurs after 5 min of illumination but also in darkness (Supplementary Fig.1aand Supplementary Note1), indicating that the process is thermally-driven and proceeds efficiently at ambient ...
is proportional to the light intensity, the scattering coefficient and the section length: 光线沿着某个方向传播过程中散射失去的光强与光的本来强度以及传播距离成正比,其公式给出如下: (2) Since scattered amount of light is removed from the initial intensity, light attenuation by out-scattering is give...
As an important parameter on light propagation analysis, a mode is defined as an electromagnetic field pattern that propagates in a waveguide (Large et al., 2008), regardless to its intensity distribution, since optical losses lead to reduction in the magnitude, without changing the distribution ...
