However, most of the optimal techniques follow computationally demanding, time consuming, iterative procedures that usually result in non-robustly stable models with poor frequency response resemblance to the original high order model in some frequency ranges.
The removal of sites with poor frequency estimates (| F E | > 0.1 in at least two populations) results in a marked change in the distribution of H, with a significant drop in the frequency of sites with large H and a shift in the distribution toward lower values.
Service planning guidelines often encourage coverage, but the result in low density areas is bus kilometres are spread thinly over a large area with poor frequencies.
These results are thus consistent with the good features of the novel enzyme-immunoassay and with a poor frequency of naturally induced specific anti-microbe antibodies in children and in adults despite the presence on recurrent respiratory infections in their clinical history.
Metal-in-metal (MIM) devices have been reported to achieve up to 35 nF/mm2[14] and more recently near 1,000 nF/mm2[12], but with poor operating frequency.
However, the mutant is also associated with poor germination frequency, low seed viability, and high pollen sterility.
In addition to capital investment, electrification is necessary for solving Caltrain's problem of poor frequency.
For example, in [8], an ANC system using a loudspeaker with poor low-frequency response was stabilized in the FFT domain by zeroing out the low-frequency components, preventing adaptation at those frequencies.
On the other hand, it is known that frequency-domain adaptive filters do not suffer from these problems despite being (nearly) equivalent to subband adaptive filters, be it with "poor" filter banks (modulated sinc frequency responses).
Second, we observed that the presence of elafin-positive cells, even at low frequency, correlated with poor outcome and clinicopathological markers of aggressive tumor behavior.
However, the presence of elafin-positive cells in invasive breast tumors, even at low frequency, correlated with poor recurrence-free survival (RFS), reduced overall survival (OS), and clinicopathological markers of aggressive tumor behavior.
