Data analysis software provides a profile of the separation, precisely calculates the sizes of the fragments, and determines the microsatellite alleles present in the sample (Figure 2). Figure 2. Electropherogram in fragment analysis.The electropherogram is a ...
Clustering is an unsupervised learning method that organizes your data in groups with similar characteristics. Explore videos, examples, and documentation.
Spectrometer is an umbrella term which describes an instrument that separates and measures spectral components of a physical characteristic.
number of bands, each associated with a vibrational mode. The spectrum is unique to the material and enables you to identify it. Some researchers aim to fully understand each Raman band and how it relates to vibrational modes. However, most analysts simply identify samples using aspectral ...
To interpret these observations, we used the SEM2DPACK spectral element code (Ampuero, 2012) to simulate colliding ruptures in a 2D in-plane geometry. A linear slip-weakening friction law with uniform properties is assumed along the contact interface. A uniform initial normal stress was applied,...

A summary of most of the state of the art before Guth-Maynard may be found in Table 2 of this recent paper of Trudgian and Yang; it is complicated, but it is easy enough to get a computer to illustrate it with a plot: (For an explanation of what is going on under the assumption...
