Multiple traits are used in this approach to examine (a) similar or (b) dissimilar traits (), in order to establish convergent and discriminant validity between traits. . Similarly, multiple methods are used in this approach to examine the differential effects (or lack thereof) caused by method specific va
Modifications that greatly enhance computational efficiency and memory scalability of mesh partitioning for parallel calculations. New constant lift mode. Specify a target lift coefficient rather than a fixed angle of attack. Upgrades to the CGNS mesh reader for further support of mixed-element meshes. General bug fixes and maintenance.
Multimethodology or multimethod research includes the use of more than one method of data collection or research in a research study or set of related studies.Mixed methods research is more specific in that it includes the mixing of qualitative and quantitative data, methods, methodologies, and/or paradigms in a research study or set of related studies.
Rather than studying particular individuals across that whole period of time (e.g. 20–60 years) as in a longitudinal design, or multiple individuals of different ages at one time (e.g. 20, 25, 30, 35, 40, 45, 50, 55, and 60 years) as in a cross-sectional design, the researcher chooses a smaller time window (e.g. 20 years) to study multiple ...
The conjugate gradient method can be derived from several different perspectives, including specialization of the conjugate direction method for optimization, and variation of the Arnoldi/Lanczos iteration for eigenvalue problems. Despite differences in their approaches, these derivations share a common topic—proving the orthogonality of the ...
Parallel metaheuristic is a class of techniques that are capable of reducing both the numerical effort [clarification needed] and the run time of a metaheuristic. To this end, concepts and technologies from the field of parallelism in computer science are used to enhance and even completely modify the behavior of existing metaheuristics.
Convergent evolution—the repeated evolution of similar traits in multiple lineages which all ancestrally lack the trait—is rife in nature, as illustrated by the examples below. The ultimate cause of convergence is usually a similar evolutionary biome , as similar environments will select for similar traits in any species occupying the same ...
Han et al. described a method that made it possible to keep the advantages of both the high efficiency of S&P synthesis and that of a homogeneous media in the chemical reactions. [13] In their method polyethyleneglycol (PEG) was used as soluble support in S&P synthesis of peptide libraries. MeO-CH 2-CH 2-O-(CH 2-CH 2-O)n-CH 2-CH 2-OH
