Emphasis is placed on examining the effects of each constituent component design of the MEA, including catalyst layers, microporous layers and membranes, on each of the three water crossover mechanisms: electro-osmotic drag, diffusion, and convection.
Effects of each component were identified numerically by principal component estimate, and a corresponding linear regression model was obtained.
35, 87 113] have developed a general linearizable kinetic structure which allows the representation of activation and/or inhibition effects of each component in the culture.
Using a component level intercomparison and the piggyback approach, we can discuss the effects of each component separately and obtain knowledge that would improve the parameterization of global scale models or regional models with coarse resolution.
Fe3O4/Fe1−xS@C@MoS2 nanosheets composed of Fe3O4/Fe1−xS nanoparticles inserted in carbon nanosheets and encapsulated by MoS2 were fabricated by Pan et al., and presented excellent electrochemical performance owing to the synergistic effects of each component [33].
For the primary study outcome, we will use a mixed-effects model with a random intercept (to account for repeated measures) to assess the main effects of each component (inclusion of motivational interviewing in the exercises, duration of the intervention, and inclusion of booster sessions) from a full factorial model controlling for baseline activity.
We then present a simulation study that demonstrates that depending on choice of the above components even strong signals can fail to be detected with routine sample sizes and that the effects of each component on statistical power are large and compounded.
In both cases, the net effect exceeds the additive/subtractive effects of each component [ 13, 14].
Table 3 shows the significant P-values for the main effects of each component.
For this reason, the present evaluation could not include an analysis of the effects of each component in the program.
