To eliminate such abnormal efficient points, there are many papers to introduce various concepts of proper efficiency; see [1 8].
The Na//Na0.67[Ni0.4Co0.2Mn0.4]O2 cell delivers a reversible capacity of 167 mA h g−1 and exhibits excellent cycling and rate performances without abnormal initial coulombic efficiency.
The second is the line-drawing problem" Schwarthe line-drawingcomes in two related guises: how we are to reference classes and how we can distinguish between normal and abnormal levels of functional efficiency.
For instance, a merit of SFA is that particularly high observed efficiency values (abnormal values) are obtained compared to other samples and the stochastic production frontier can absorb a significant part of the impact of these abnormal values, symmetrically, in the error term.
Additionally, for a sample with particularly high observed efficiency values (abnormal values) compared to other samples, in DEA, the efficiency frontier is determined to include these observed values as a technically completely efficient sample, since a negative deviation from the frontier is not allowed.
Although the Separase mutation induced similar mitotic defect in male and female PGCs, the above results indicated that there was an apparent sex-specific difference in the efficiency of abnormal PGC depletion.
Small size of nanorods makes them potentially useful for drug delivery and gene therapy, hence, provides drug delivery system with lower cytotoxicity towards normal cell and increased chemotherapeutic efficiency towards abnormal cancer cell [ 71].
Regarding the productive stages, the perturbation in seed development under drought stress may produce shrunken seeds, which contain low protein and starch content, reducing the germination efficiency and causing abnormal seedling development (Wood et al. 1977; Guo et al. 2012).
In order to obtain high volumetric efficiency and eliminate abnormal combustion modes such as preignition and backfire, in-cylinder direct injection (DI) of hydrogen is considered preferable for a future generation of hydrogen IC engines.
Careful attention to the display of the information could increase physician attention to abnormal results without decreasing their efficiency [ 19].
