With over 100 degrees of freedom, the minimum sample size was 132 to achieve a power of.80.
This converter is used as PFC due to its capability to achieve a power factor close to unity.
Our goal was to achieve a power of 80%% for a 0.05 significance level (alpha error) using a two-tailed unpaired t test.
With a group distribution of 3/1 and a type-1 error risk of 0.05, the inclusion of 56 patients was necessary to achieve a power of 80%.
A power factor correction function is incorporated in the shunt active filter to achieve a power factor that is near to unity.
We conclude that, with the price of slightly increased complexity, the proposed systems could be an effective solution to achieve a power saving and better average BER performance for WBAN applications without sacrificing the data rate.
Each cluster is assigned a normalized amplitude A i that is computed from the tabulated cluster powers P i as A i = P i ∑ i = 1 I P i (49). in order to achieve a power normalization.
Proposed PEH works at non-resonance and its resistive impedance matching is reduced to half, to 250 kΩ by connecting the two beams in parallel and to achieve a power output of 4 mW.
To achieve a power of 80% to detect superiority between regimens, mouse relapse studies with 20 animals per group require an absolute difference of 40% in relapse rates between regimens [26], [27].
To achieve a power of 80% to demonstrate non-inferiority with an acceptable non-inferiority margin, the numbers of mice required in each group are much higher than those used in the current study.
To achieve a power of 80%, 11 patients would be required.
