Separation of a sum of chaotic signals corrupted by Gaussian channel noise into the components with a method based on chaotic synchronous response is discussed. In order to establish the response, a procedure of iterating the maps, inverse to the maps that generate the chaotic signals, is proposed. ...

Data in GIPSY is stored in so called sets . A set consists of two components: an image component and a descriptor component. These components are stored in separate files, but in GIPSY they are always used together. The image data is stored in a `crystalline' structure with a virtually unlimited (up to 20) number of dimensions. ... Within a set subsets can be defined. ... The figure below shows the possible subset types in a three-dimensional set, a `` cube '': . ...

Next: Stellar models Up: Introduction Previous: Photometry Contents . In a hierarchical stellar system, the separation between two neighboring stars is always much smaller than the separation of this pair from the next companion in the system, be it another pair or a single star. ... They are also numerically easier to handle than non-hierarchical systems, since each pair can be described with the standard orbital parameters, and each star with a small number of physical parameters. ...

... 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. ...

The notion of ions first arose in chemistry. In the 19th century it was well known that water in which salts were dissolved (or acids, or bases) conducted electricity, and that an electric current could separate such dissolved materials into their components. ... In 1898 Ernest Rutherford noted that the radiation seemed to contain two electrically charged components of opposite signs, steered by a magnet in opposite directions--positive "alpha rays" and negative "beta rays." ...
