Factor analysis — is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved, uncorrelated variables called factors. In other words, it is possible, for example, that variations in … Wikipedia
True RMS converter — When measuring the value of an alternating current signal it is often necessary to convert the signal into a direct current signal of equivalent value (known as the RMS, root mean square, value). This process can be quite complex (see root mean… … Wikipedia
Power factor — For other uses, see Power factor (pistol). The power factor of an AC electric power system is defined as the ratio of the real power flowing to the load over the apparent power in the circuit,[1][2] and is a dimensionless number between 0 and 1… … Wikipedia
Impact factor — The impact factor, often abbreviated IF, is a measure of the citations to science and social science journals. It is frequently used as a proxy for the importance of a journal to its field.OverviewThe Impact factor was devised by Eugene Garfield … Wikipedia
Distortion power factor — The distortion power factor is used in power electronics to describe how the harmonic distortion of a load current decreases the average power transferred to the load. Distortion power factor is an important factor in the calculation of true… … Wikipedia
Architectural design values — make up an important part of what influences an architect and designer when they make their design decisions. However, architects and designers are not always influenced by the same values and intentions. Value and intentions differ between… … Wikipedia
D-factor — The difference between the values of “time altitude minus pressure altitude” taken at two different times in flight. It is the difference between indicated height and true height when an aircraft is flying over the sea. Also called D value … Aviation dictionary
Principal component analysis — PCA of a multivariate Gaussian distribution centered at (1,3) with a standard deviation of 3 in roughly the (0.878, 0.478) direction and of 1 in the orthogonal direction. The vectors shown are the eigenvectors of the covariance matrix scaled by… … Wikipedia
Principal components analysis — Principal component analysis (PCA) is a vector space transform often used to reduce multidimensional data sets to lower dimensions for analysis. Depending on the field of application, it is also named the discrete Karhunen Loève transform (KLT),… … Wikipedia
Independent set problem — In mathematics, the independent set problem (IS) is a well known problem in graph theory and combinatorics. The independent set problem is known to be NP complete. It is almost identical to the clique problem. Description Given a graph G , an… … Wikipedia
APX — For other uses, see APX (disambiguation). In complexity theory the class APX (an abbreviation of approximable ) is the set of NP optimization problems that allow polynomial time approximation algorithms with approximation ratio bounded by a… … Wikipedia
