There is going to be a feeling that the program is running in parallel, even if it is being run on a single-processor machine.I demonstrate how to perform an eigenvalue Monte Carlo simulation (a.k.a., parallel analysis in the behavioural sciences) using Brian O'Connor's SPSS syntax,...
In a series RLC circuit there becomes a frequency point were the inductive reactance of the inductor becomes equal in value to the capacitive reactance of the capacitor. In other words, XL = XC. The point at which this occurs is called the Resonant Frequency point, ( ƒr ) of the circuit, and as we are analysing a series RLC circuit this ...
Parallel diodes can be forced to share current by connecting a very small resistor in series with each diode. In Figure 3, the current-sharing resistor R establishes values of ID1 and ID2 that are nearly equal. Although current sharing is very effective, the power loss in the resistor is very high. Furthermore, it causes an increase in voltage ...Exploratory mediation analysis. The fundamental goal of mediation analysis is to determine the process by which a variable X influences another variable Y (MacKinnon, Lockwood, & Williams, Citation 2004).Exploratory mediation analysis (EMA) in particular is used to explore a dataset for potential mediating variables (MacKinnon, Citation 2008).In other words, EMA pertains to determining among ...
Parallel Analysis (PA) was applied for each PCA/FA found in the literature. Of 39 analy ses (in 22 articles), 29 (74.4 %) considered no threshold rule, presumably retaining interpretable components. According to the PA results, 26 (66.7 %) overextracted components.chance. Although the parallel analysis approach appears to do well at identifying the correct number of factors (Fabrigar & Wegener, 2002), it is not widely available in software packages. I recommend the scree plot approach (or the Cattell-Nelson-Gorsuch modified scree test thatDong et al31 propose a prediction and analysis tool named ProteinSPA, which employs a specific protein structure prediction workflow designed to be executed in grid environments that integrates several bioinformatics tools in parallel.
