Example: "The desired outcome can be achieved by decreasing the amount of waste produced during the manufacturing process."
Alternatives: "attained through reduction" or "realized by lowering".
A sustainable recovery can only be achieved by decreasing inequality.
This reduction could be achieved by decreasing calorie intake, increasing physical activity, or both.
This is achieved by decreasing the bulk velocity and the diameter of the fuel nozzle with increasing pressure.
In Abu Dhabi, Boston, and Singapore, efficient operation is achieved by decreasing the arch truss depth and height to reduce the interior conditioned volume and the envelope surface area — a change that also reduces structural efficiency.
An additional order of magnitude increase of PG/DNA assay sensitivity (~ 1 pg/ml) can be achieved by decreasing the PG concentration.
Increasing the CS proportion (i.e., at the expense of AS) in the diet was achieved by decreasing the corn grain proportion and increasing that of soybean meal.
This is achieved by decreasing the actions that a node needs to perform at the start of every communication period and by incorporating a variable radio-on operation.
Particularly, the significant increase of the thrust, which is achieved by decreasing the number of the primary coil turns, occurs at low velocities.
An improvement of system performance can also be achieved by decreasing either the thermofluid's Fourier number or the bed's Biot number.
Finally, a case study for the diameter of the reactor tube showed that a higher conversion could be achieved by decreasing the size of the reactor tube.
In medium urbanization areas, the same increases in TD and AGB could be more effectively achieved by decreasing the IJI and Area-Weighted Mean Contiguity (CONTIG-MN).
