The Q criterion is written as Q = 0.5*(vorticity 2 - strain rate 2) > 0 meaning relative dominance of the rotational component over the stretching component in deformation of a fluid element.

Plot of Δ-Criterion Name = 'Global_Q Criterion'; PlotName = strcat('Q Criterion', Num); Purpose: Used to zones and 263 million cells, calculating Q Criterion using Calculate Variables was more than six times faster than a macro we provide for the calculation.

Q-Q plots are a useful tool for comparing data. For most programming languages producing them requires a lot of code for both calculation and graphing. R, on the other hand, has one simple function that does it all, a simple tool for making qq-plots in R . Topic: how to make a QQ plot in r

This manual describes a complementary approach: writing your data in the Tecplot 360 data format so it can be read natively, providing the best experience for Tecplot 360 users.This Data Format Guide includes the following topics: criteria that remain invariant under coordinate changes of the form y=Qx + at, where Q is a proper orthogonal tensor and a is a constant velocity vector. For a three-dimensional smooth velocity field v(x,t), available Galilean-invariant vortex criteria use the velocity gradient decomposition ∇v = S+Ω, (1.1) where S= 1 2 Tecplot is the name of a family of visualization & analysis software tools developed by American company Tecplot, Inc., which is headquartered in Bellevue, Washington.

Google has many special features to help you find exactly what you're looking for. Criteria for ischemic T-wave inversions. T wave inversion ≥1 mm in at least two anatomically contiguous leads. These leads must have evident R-waves, or R-waves larger than S-waves. Pathological (infarction) Q-waves. Pathological Q-waves arise arise if the infarction is extensive, which is usually not the case in patients with NSTEMI.
