The phrase "achievable ideal" is correct and usable in written English.
It can be used when discussing a goal or standard that is realistic and attainable within certain constraints.
Example: "While perfection may be out of reach, we can strive for an achievable ideal in our project outcomes."
Alternatives: "realistic goal" or "attainable standard".
The original Erice Declaration of 1997 was a visionary statement of the achievable ideals for drug safety communication at the time, much of which remains potent and relevant today.
Furthermore, the effective efficiency of such refrigerators is far below that achievable under ideal (e.g. optimal-load; minimum access) operation.
[Though] not universally achievable, the ideal, best environment for children is within a two‐parent family based on the principle of marriage between one man and one woman.
■ Coverage 1 and Coverage 2 denote the upper bounds for coverage for screening and vaccination, respectively; these are selected to represent either readily achievable or ideal values.
The upper bound is achievable only for ideal channels, and the CLD approaches the upper bound by an amount proportional to the given channel quality.
This simple network model assumes an ideal achievable transmission rate per hertz through the Shannon's law, and that the base station has ideal knowledge of the user's Signal-to-Interference Ratio (SIR).
This makes ideal security achievable, but it is clearly not practical in real-time applications as the resulting data communication cost would be high, especially if only a small portion of the data is queried.
If this structure is turned into a truncated cone with 250 nm top diameter, the short circuit current density can be further increased by 9.4% to 15.2 mA/cm 2. In general, the achievable enhancement or the ideal geometry depends strongly on all geometric factors like diameter, length, and pitch influencing again the tradeoff between volume and effective index of refraction.
In both cases, defenders argued that the failure to conduct such research constitutes greater harm by depriving disadvantaged populations of the benefits of achievable albeit less than ideal improvements in health (Buchanan and Miller 2006).
