The phrase "active index" is not correct in standard English; it likely refers to "refractive index." You can use it in contexts related to optics or physics when discussing the property of a material that affects how light travels through it.
Example: "The refractive index of the glass determines how much light bends when it enters the material."
Alternatives: "refractive index" or "optical index."
For each x ∈ X, let T ( x ) be the active index set of system (3.1), that is, T ( x ) : = { t ∈ T : f t ( x ) − g t ( x ) = 0 }.
The solid mixing behaviour was estimated based on the dispersion coefficient of particles, the active index (AI), and the distribution of particle residence time within the entire bed.
The density calculated by the NRLMSISE-00 model without using the geomagnetic active index as input is taken as a reference on top of which the storm-time changes are added.
I is nonempty and the family of rows a i, i ∈ I of the matrix A is linearly independent, there is some y ∈ P such that I is contained in the active index set I ( y ) at y, that is, a i y = b i, i ∈ I ; A I is the submatrix of A consisting of the rows a i, i ∈ I, and A I T is its transpose.
These qualitative responses were converted into nominal categories ranging from 0 to 4. The active indicator index was then calculated (problem solving + student presentations)/(problem solving + student presentations + lecture).
The MA-based sparsity detection described in Section 4.1 relies on searching for active channel indices and terminates when all the active indices have been identified.
So, the set of all feasible solutions and the set of constraint active indices for either (CVP) or (G-CVP) are denoted by E and J ( x ¯ ), respectively.
Furthermore, urinary tumor necrosis factor-like weak inducer of apoptosis (TWEAK) levels were correlated with all active indexes of LN, suggesting its potential role as a novel biomarker of active LN [80].
Active (physical activity index = 1) was defined as recreational activity 1 2 times/week, >20 minutes/time or >2 times/week but <20 minutes/time.
active power performance index and reactive power performance index are computed for a large power system using a special code written in MATLAB environment.
A high activity index signifies active yet reversible disease, whereas the chronicity index shows irreversible damage.
