WebDec 4, 2024 · Brillouin diversity index. The Brillouin index describes a known collection: it does not assume random sampling in an infinite population. Pielou (1975) and Laxton (1978) argues for the use of the Brillouin index in all circumstances, especially in preference to the Shannon index.

WebMar 1, 2024 · Brillouin's index estimated a diversity index of 3.545, with a relative value of high diversity (MacDonald 2003). The three diversity index proved that the LMF has a diversity value of high to very high species diversity, with an evenness index of 0.827 or 83% of species are common or shared among plots within habitat types (Figure 4). WebAcoustic signals or sound waves that impact the fiber cause small changes in the refractive index. These changes can be detected with Rayleigh backscatter when using a coherent optical time-domain reflectometer (COTDR). Standard singlemode optical fiber is typically used. Brillouin backscatter is used for strain and/or temperature measurements.
WebMcIntosh's Index is based on a geometric model: u = (Ni2) e.g., N=7; N1=3, N2=4 u = (Ni2) = (32+ 42) = 5 = length of vector from origin e.g., N=10; N1=2, N2=3, N3=5 u = (Ni2) = (22+ 32+ 52) = 6.1644 From this, McIntosh defined an equitability index: M = N - u An obvious disadvantage is that M = f(N); however, M can be normalized (Peet 1974):
