## square root:

see rootroot,
in mathematics, number or quantity r for which an equation f(r)=0 holds true, where f is some function. If f is a polynomial, r is called a root of f; for example, r=3 and r

The derivative action of the Atan and Sqrt schemes is bounded, while that for the proposed hyperbolictype control is linear, demanding the effect of damping injection as needed.
[V.sub.t](s) = int [min (sqrt (2as), [V.sub.y])], (7)
Because the CLSI was positively skewed (skewness = 1.13, p < .01) while the BAPC-AR was negatively skewed (skewness = -.61, p < .05), square root transformations (SQRTs) were conducted to approximate normality for these variables.
For example, sqrt 4 may yield 2 or -2, and we do not know or care which.
The F and p values for the electrodermal lability main effect were: SQRT maximum SCR F(1,22) = 5.43, p = .03, MSE = 0.24; SQRT total SCR F(1,22) = 5.09, p = .03, MSE = 0.27; SCR count F(1,22) = 3.33, p = .08, MSE = .098; indicating generally more electrodermal activity in the labile participants than the stabile ones.
It then processes the arguments to the sqrt, specializing the multiplications to COMPUTE-SQUARES, and the addition to COMPUTE-SUM-OF-SQUARES.
The structure of the proposed 16-b SQRT CSLA using BEC for RCA with cin = 1 is to optimize the area and power.
Plots of measured and predicted values for sqrt_OC, sqrt_POC, sqrt HOC and sqrt ROC and selected statistics (slope, offset, [R.sup.2], RMSE and R+PD) are presented in Fig.
As we can see, the BPTrust could normally infer a rational value for node 1 while the multiplication needs a SQRT function.
Accordingly, the distance between terms [t.sub.2]&[t.sub.3] is given by disf([t.sub.2],[t.sub.3])= sqrt ([(35-20).sup.2] + [(20-30).sup.2] + [(4-6).sup.2] + [(14-12).sup.2] + [(0-0).sup.2]) =18.248 when the term is represented as vector of frequencies.
[I.sub.[beta]] = sqrt (3)/3* ([i.sub.1] +2* [i.sub.2]);
Microstrip Unbalanced Stripline Differential Impedance Differential Impedance (for traces routed (for traces embedded on an outer layer) between planes) Zo = 87 / Sqrt (Er + 1.41) * Zo = 80 / Sqrt Er * ln (1.9 (2H + (ln (5.98H / (0.8W + T)) T) / (0.8W + T)) * (1 - (H / 4 (H + C + T))) Zdiff = 2 * Zo (1 - 0.48 Zdiff = 2 * Zo (1 - 0.347 [e.sup.-0.96D / H]) [e.sup.-2.9D / B]) where W = trace width T = trace thickness H = distance to nearest reference plane Er = dielectric constant D = trace edge to edge spacing C = signal layer separation B = reference plane separation
