The phrase "a proved efficient technique" is not correct in standard written English.
The correct term is "a proven efficient technique," which is used to describe a method that has been tested and shown to be effective.
Example: "The researchers implemented a proven efficient technique to improve the accuracy of their results."
Alternatives: "a validated efficient technique" or "an established efficient technique."
This paper presents a more efficient approach consisting of a flatting pre-processing technique, a proved efficient ordering heuristic and a bottom-up generation algorithm.
This strengthening technique proved efficient with respect to ultimate and serviceability states.
Importantly, a MSP3 based vaccine proved efficient in a phase 1b vaccine trial [ 21].
The color measured by diffuse reflectance spectroscopy proved efficient to indicate variations among the ADEs, proving to be an innovative technique, efficient and promising for indirect quantification of soil characteristics in a simple and low cost manner.
The interior proved efficient.
RSM method, proved as an efficient technique for optimizing process conditions which resulted in 110% increase in SK production, 2352 IU/mL, than for unoptimized conditions.
To quantify the magnitudes of these forces in saltation we used high-speed multi-flash photography to observe the movement of saltating sand grains in a wind tunnel; this proved to be an efficient technique for determining the movement and rotational velocities of grains of natural sand with grain sizes ranging from 0.2 to 0.3 mm and shear velocities (u⁎) of 0.67, 0.83, and 0.87 m s− 1.
These techniques have been economically sustainable and also proven efficient in natural product discovery.
As a complementary approach, the cDNA-AFLP analysis proved to be an efficient technique for the isolation of differentially expressed transcripts without any sequence similarity assumption.
Though proven efficient in many studies, this method has a number of drawbacks.
