2. Principal Components Analysis
... Among the objectives of Principal Components Analysis are the following. dimensionality reduction; љ . the determining of linear combinations of variables; љ . ... identification of groups of objects or of outliers. ... Finding a set of principal axes allows the objects to be adequately characterised on a smaller number of (artificial) variables. ... Reduction of dimensionality is practicable if the first new axes account for approximately 75 % or more of the variance. ...

3. A Computer-Based Technique for Automatic Description and Classification of
... A technique allowing automatic representation by a relatively small number of independent parameters based on the principal component analysis of data sequences is presented. ... In recent years the spectrum of observed astronomical data can be characterized as greatly varied. ... In this instance, the problem of initial description and classification of newly-observed data becomes most urgent, especially if there is a lack of preliminary observational material and theoretical expectations. ...

5. Constraints on the model components:
... The fitting procedure will only converge to a unique solution if the components are linearly independent. ... The task calculates for each pair of component images and fails with an error if any is greater than 0.99. ... Hence components may be linearly independent in masked pixels yet still fail the test within the task. ... Finally, since the Poisson image values are necessarily all , negative values are not allowed in the model components. ...

10. An Ultraviolet-to-Radio Broadband Spectral Atlas of Nearby Galaxies
The ultraviolet-to-radio continuum spectral energy distributions are presented for all 75 galaxies in the Spitzer Infrared Nearby Galaxies Survey (SINGS). ... These results suggest that the star formation history may be the dominant regulator of the broadband spectral variations between galaxies. Finally, a new discovery shows that the 24 ЮМm morphology can be a useful tool for parameterizing the global dust temperature and ultraviolet extinction in nearby galaxies. ...

14. Detection of radio pulsar pairs
... According to modern views on the evolution and origin of stars, most of the stars are members of binary systems. ... After the second explosion, the pairs tend to break up and neutron stars and/or black holes fly apart. High velocities of radio pulsars are apparently largely due to this effect. ... For all possible pairs the probability of trajectory approach at small distances for the epoch, corresponding to the age of the younger pulsar have been evaluated. ... Pulsars J0543+2329 and J0528+2200. ...
