Next, we describe how to determine the system sensitivity. We then describe the ways in which you can determine the exposure time required for a given observation and the signal to noise that will be achieved; examples are provided. ... We also describe how to calculate signal to noise ratios and exposure times by hand for NICMOS. ...

This module provides for user authentication using MD5 Digest Authentication. Status: Experimental . ... Module Identifier: digest_auth_module . Compatibility: Available in Apache 1.3.8 and later. ... If you use this module, you must make sure to not use mod_digest (because they share some of the same configuration directives). ...

... This page describes the format of the skin template files (.tmpl) that are used to create PmWiki skins . ... Each skin must include a template file that provides the skeleton for displaying a PmWiki page. A template file is basically an HTML file that also contains variable substitutions (indicated by '$') and special directives embedded in HTML comments. ... When PmWiki displays a page, it replaces the directives and variable substitutions with the values appropriate to the current page. ...

... grep -s keith > /dev/null then echo keith is logged in else echo keith not available fi . This lists who is currently logged on to the sytem and pipes the output through grep to search for the username keith . The -s option causes grep to work silently and any error messages are directed to the file /dev/null instead of the standard output . If the command is succesful i.e. the username keith is found in the list of users currently logged in then the message keith is logged on . ...

This diagram shows the six superimposed "layers" of the CSS table model. This diagram illustrates the algorithm for calculating a cell's final background. ... The diagram shows how, looking down on the six rectangles, one may compute the background color of each cell. ... A cell without a background color in the top layer is depicted as a "window" onto the lower layers, which give its final background color. ...

... Microlocal Analysis is a theory of Pseudo-Differential Operators and Fourier Integral Operators (PDOs and FIOs). ... Microlocal analysis comes in few flavors. ... We will consider semi-classical PDOs and FIOs: one can always get from there to standard PDOs and FIOs but semi-classical theory has more applications. Less formal description of (semi-classical) microlocal analysis is ``a semi-classical limit of quantum mechanics'' or ``high-frequency limit of electrodynamics'' (etc). ...

For the last few decades InformChaos Lab of the Institute of Radio Engineering and Electronics of Russian Academy of Sciences studies chaos and complex dynamics of nonlinear systems. In 2000 as a result of these studies we proposed a concept of Direct Chaotic Communications (DCC) . Testbeds of wireless communication systems demonstrated transmission of information with rates up to 200 Mbps. Chaotic (noise-like ) oscillations of deterministic systems are used as information carriers in DCC. ...
