This was fine when the aircraft was flying at 15000 feet or more and the ground return was at about the maximum useful range, but meant that interceptions at lower altitudes offered increasingly shorter range.
This source of noise ultimately limits the maximum useful signal amplification that can be provided by a receiver.
Let δ G be the maximum useful chemical work that the growth (biosynthesis) of a phytoplankton cell can perform.
Regarding the phytoplankton as a single averaged species, in the chemostat in the steady state the rate of cell growth is D P S. One may suppose the maximum useful work per cell to be K I, where I is the light energy absorbed per cell and K is the efficiency.
The maximum useful range of the traditional Arabian bow was about 150 m.
The maximum useful magnification of an image is usually set at ∼1000 times.
In the μ′ s = 3.6 mm−1 phantom, the maximum useful signal from the 1.0 mm solid-core fiber is 808 counts/ms, compared with only 0.420 counts/ms from the fiber bundle.
Light microscopes have a usual magnification factor of 1000 × and a maximum useful magnification of approximately 2000 ×.
At their steady state, two apparently opposed principles for their rate of entropy production have been proposed: the minimum entropy production rate and the maximum entropy production, useful in the analysis of dissipation and irreversibility of different processes in physics, chemistry, biology and engineering.
St . Judeinvestigators found that the modeled exchange rate of contrast agent between plasma and tumor extracellular fluid space, designated kep, and the dynamic vector magnitude (DVM), which incorporates the initial rate of contrast uptake and the maximum enhancement, are useful measures of osteosarcoma viability.
Three indictors, namely, number of occupational injuries, number of employees and ratio of maximum useful hours over useful hour per month are considered as inputs.
