The scale type ( M, N) of an ordered relational structure is defined in terms of two properties, called M- point homogeneity and N- point uniqueness, of the automorphism group of the structure. For real structures on an open interval, scale types (1, 1) and (2, 2) correspond to ...

and nasolabial folds.To identify the scale by objective quantitative measurement,skin surface measurements from the Visioscan~ VC98 were used.To test the reliability and validity of our wrinkle scale,a multi-rater consensus method was used.A double-blind,randomized,vehicle-controlled 12-week study ...
In binary classification problems, the first step is to normalize the columns of the measurement matrix A, because in the objective function of the optimization problem (15), all components of the weight vector w are treated equally. In both the data replication and the one vs. all methods,...
A quantitative type of variable can be calculated, measured and/or operated with; it presents particular information on a numerical scale. From a sample of items, quantitative variables relate to the weight of the article, its temperature, its volume, height, income, results of students, or any...

While the measurement of features from spectrograms and waveforms can be expected to be more objective than onomatopoeic or functional naming, the appearance of a spectrogram, and thus the measurements made, depend on characteristics of the recording system, the time and frequency settings of the an...

The statistical classification applies flow-level measurement in the network to identify the statistical characteristics of traffic (Zhang et al., 2015). This technique is also known as rationale-based classification. (Zhang et al., 2015). The duration of the packet, packet inter-arrival time, ...
blood volume within the vessels. Therefore, when light of a constant wavelength illuminates the skin tissue, the energy of the light penetrating the tissue changes correspondingly with the fluctuations in blood volume, thus enabling the measurement of the body's pulse wave signals [30,31,32,33,...
