... As discussed in systematic errors, astronomers, like physicists, show their error components in two additive terms; statistical error + systematic error. To explain such decomposition and to make error analysis statistically rigorous, the law of total variance (LTV) seems indispensable. ... MADS] Law of Total Variance?

... Optical Science Laboratory, Department of Physics and Astronomy, University College London, London, WC1E 6BT, U.K. љ The simplex method, a data fitting method to any type of function, is refined by eliminating a redundant process. The refined method is applied to Zernike polynomials in Cartesian coordinates, which describe an optical surface or wavefront in terms of aberrations. ... Data fitting to Zernike polynomials has mainly been done by the least-squares method (Malacara et al. ...

... From about ten specimens of each, she has established `chronologies' for four species growing within ten miles of the Observatory, namely: Ash, Beech, Oak and Scots Pine. A preliminary principal component analysis using a technique developed by Dr Ed Cook has given very promising results with about 30% of the variance for Ash and Beech explained by sunshine and temperature and a similar variance for Pine and Oak explained by rainfall. ...
This module provides an environment variable with a unique identifier for each request. ... The unique identifier is even unique across multiple machines in a properly configured cluster of machines. ... On Unix machines, Apache creates several children, the children process requests one at a time. ... To distinguish time we will use a Unix timestamp (seconds since January 1, 1970 UTC), and a 16-bit counter. ... The actual ordering of the encoding is: time stamp, IP address, pid, counter. ...
