... In this paper, we present an interactive signal-processing environment called Grid. ... Grid is a graphical interactive multi-threaded signal-processing environment which allows the creation of complex arrays of algorithms (called units within Grid) by simply choosing the desired units from a selection of toolboxes then graphically wiring them together. Figure: Grid's ToolBox window consists of a section which lists the available toolboxes and another showing its associated tools. ...

It could be that SETI signals have arrived at the Earth, but are lower then the noise level, and our receivers cannot detect them. ... Fig. ... It follows that two zones form around the star with civilization X: "Zone Yes", where its SETI signal can be detected, and "Zone No", where its signals are hidden by noise (Fig. ... In practice, it is more efficient to use a time factor, since the problem of SETI contact does not limit the duration of the signal element and semantic text. ...

Next: Imaging Polarimetry with NICMOS Up: NICMOS Data Calibration and Previous: The Photometric Performance of . ... NICMOSlook and Calnic C . ... Extracting spectra from a large number of NICMOS grism images requires a convenient interactive tool which allows a user to manipulate direct/grism image pairs. ... NICMOSlook and Calnic-C are two programs that were designed to take advantage of the fact that the NICMOS grism mode typically consists of taking both a direct and a grism image. ...
