Several leading partners saw softening of the pipeline and she believes "there is a step function lower" in demand for Oracle, the analyst said.
While saying that 'it's not a step function right away,' Lachica noted that the fabrication of space-grade components will be a new sector for the semiconductor and electronic industry that would spur growth.
The model considering a 6th-order LP for additive genetic effect, a 5th-order LP for permanent environmental effect and a step function with 10 heterogeneous classes for residual variances (Leg65_10) is more appropriate.
If f : [a, b] [right arrow] X is a step function, then for every g : [a, b] [right arrow] Y, the integral (HS) [[integral].sup.b.sub.a] B(f, dg) exists.
From Figure 10, the velocity of the platform increases rapidly from 0 to expected value in the X, Z direction within 0.2 s, consistent with the variation trend of the defined STEP function. Then the velocity values in the X, Z direction fluctuate within a certain range.

Finally, the Heaviside step function [THETA](t - t') in (1) reflects causality and ensures that the spin density at time t is only influenced by the magnetic field at times t' < t, if the dynamic spin susceptibility is interpreted as the linear spin-density response function by means of Kubo's formula.
In this case, the shape of fragility curve also can be formulated by connecting the necessity measure at the center of bin instead of using step function that has the same value in a PGA interval (bin).

Residual variance were considered homogenous (hom) or heterogeneous (het) were modeled by step function with 7 (20 to 35, 36 to 50, 51 to 70, 71 to 85, 86 to 99, 100 to 120, and 121 to 140 months of age) and 10 (20 to 32, 33 to 44, 45 to 56, 57 to 69, 70 to 81, 82 to 93, 94 to 105, 106 to 117, 118 to 129, and 130 to 140 months of age) classes in total parities.
Figure 1 plots these streak sequences for the 1972 Phillies as a step function, stepping up each time a new streak starts.
When the initial distribution is relatively wide compared to [E.sub.w], the total integrand is initially following the shape of the initial distribution function, but as time proceeds, it is progressively truncated from the left by the step function, DExp.
