In tropical synoptic analysis, a locus of maximum streamline curvature in an easterly wave; used primarily in the analysis of waves that span the equatorial trough (equatorial waves); a positive axis corresponds to a trough line in the Northern Hemisphere and a ridge line in the Southern Hemisphere.

The limiting cases are thus for r a point at the origin as r [right arrow] 0, and for [theta] a line along positive axis z as [theta] [right arrow] 0 and along negative axis z as [theta] [right arrow] [pi].
Biplots between PC 1 and PC 2 scores showed that the soils collected from S1 clustered to the negative axis of PC 1 throughout the three sampling periods; however, soils collected from S2 and S3 clustered to the positive axis of PC 1 on the first sampling period (Fig.
However, in biplots between PC 2 and PC 3 scores, only soils collected from S3 on D1 were located on the positive axis of PC 2 (Fig.
tigerina is situated in the positive axis but also extends slightly to the negative axis while the other two is almost uniformly distributed towards zero suggesting a much closer resemblance to the mean shape.
bengalensis draw towards the positive axis, while C.
with [theta] measured anticlockwise from the positive axis Ox.
Note also that because the argument must always be measured anticlockwise from the positive axis Ox, then in this case [theta] = 298.
Then A is commutative if and only if there exists a convex function on the positive axis I = [0, [infinity]) which is not a 2-convex function f but an A-convex function.
Conversely, suppose that there exists a convex function on the positive axis I = [0, [infinity]) which is not 2-convex function fbut an A-convex function.
The multivalent term' discipline' is examined by various contributors, giving due attention to both the nexus of control and punishment and to the essentially more positive axis of being a disciple.
10] m along positive axis z; a nodal surface of zero amplitude, of paraboloidal shape, exists between a large positive lobe, extending mostly along positive axis z, and a small negative lobe, extending along negative axis z.
1,0,0] across the plane z = 0: a small positive lobe hence extends along positive axis z and a large negative lobe along negative axis z; the centre of the surface of [[psi].
