The phrase "are considered as efficient" is not correct in standard written English.
It is typically used when discussing the efficiency of methods, processes, or systems, but the word "as" is unnecessary.
Example: "These new algorithms are considered efficient in processing large datasets."
Alternatives: "are regarded as efficient" or "are deemed efficient."
Aqueous two-phase systems (ATPS) are considered as efficient downstream processing techniques in the production and purification of enzymes, since they can be considered harmless to biomolecules due to their high water content and due to the possibility of maintaining a neutral pH value in the medium.
Then, many image segmentation algorithms based on the fuzzy theory are widely studied and are considered as efficient ways because they can describe the fuzzy uncertainty of images excellently [39].
Members of the Bacillus genus are considered as efficient microbial factories for the large scale production of such type of bioactive molecules [ 4, 5].
Global optimization methods can be considered as efficient tools to face this problem.
Interference study and performances show that SPE-cyclam could be considered as efficient sensors for environmental analysis.
The obtained results show that a series of recently synthesized azafluoranthene dyes may be considered as efficient green fluorescent emitters for electroluminescent applications.
The roller nano-imprint technology is considered as efficient and low cost method for the large scale micro-pitch grating fabrication.
If wetland water consumption is considered as efficient use, this fraction of the irrigation water loss becomes efficient use, which will increase the system efficiency proportionally by the percentage of wetland water consumption.
The energy barriers obtained for these reactions show that these systems can be considered as efficient olefin polymerisation catalysts, but less active than their metallocene counterparts, in agreement with experimental findings.
Data warehouses (DW) are being considered as efficient components of decision support systems [7].
In this sense, the sort done by the tracking system cannot be considered as efficient.
