Data Analysis

The NMR spectrum of a sample can be considered an object in a multidimensional set of metabolic coordinates, the values of which are the spectral intensities at each data point. Similarity or differences between samples can then be evaluated using multivariate statistical methods or other pattern-recognition (PR) approaches.[7]

The general aim of PR is to classify an object based on identification of patterns in a set of experimental measurements or descriptors. It can also be used for reducing the dimensionality of data sets, e.g., using 2-D or 3-D mapping procedures, to enable easy visualization of any clustering of the samples. Data can be modeled using PR techniques so that the class of separate samples (a ''validation set'') can be predicted based on a series of mathematical models derived from original data or ''training set.''

Getting Started With Dumbbells

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
