Where [F.sub.LA] is the

modulation factor from the luminance adaptation, [F.sub.M] is another

modulation factor from the contrast masking, [T.sub.B] refers the base threshold.

The

modulation factor behaves like the amplification factor.

The modulation factor (MF) was used to evaluate the modulating effects of compounds on MICs of antibiotics according to the following formula: MF = MIC antibiotic/MIC antibiotic + modulator.

Table 1 Minimum inhibitory concentration (MIC), modulation factor (MF), and fractional inhibitory concentration (FIC) values of antibiotics and ethidium bromide alone and in combination with compounds 1-13, for S.

The symbols [[sigma].sub.init], [[sigma].sub.fin] represent, respectively, initial and final values of the standard deviation, whereas m is a nonlinear modulation factor. Taking into account that the distance between plants can be interpreted as the number of transformations of the parent individual, value computed by the normal distribution generator is rounded to the nearest integer value.

From the Fourier transform of (6), the

modulation factor loss K in a harmonic radar case can be obtained as

The section S2 is switched off from the myocardial contractility circuit, thereby decreasing the

modulation factor from 1 to 0.17.

Any offset between [T.sub.sky] and [T.sub.ref] "can be balanced before differencing either by a variable back-end gain stage with a feedback scheme to maintain the output power as close as possible to zero, or by multiplying in software one of the two signals by a so-called gain

modulation factor" [47].

The NFU's outright rejection of the

modulation factor - which is seen as robbing Peter to pay Paul - is understandable.

is the

modulation factor. The elementary frequency variation g(t) results from a convolution between the rectangle function rect(t) that define the digital pattern and the unit pulse response of the Gaussian filter h(t)

Over the years Denzil signed up to Tir Mynydd, the old hill land compensatory scheme with flock and suckler cow payments; then Tir Gofal, which worked around a points system for conservation issues and now Tir Cynnal, which is concerned with the environment and is intended to work around

modulation factors.
