Catalytic filters should possess the following properties: 1) high thermal, chemical, and mechanical stability; 2) high dust separation efficiency attained by cake filtration (no penetration of particulates into the filter structure); 3) low cost; 4) high catalytic activity (operation at high superficial velocities); and 5) low pressure drop. Saracco et al. tested several filter types and catalysts, and reported their best filter to be a candle filter made from porous -Al2O3 with an average pore size of 15 m and a catalytically active surface coating of V2O5 and TiO2 (anatase) [6]. This functions as a cake filter for fly-ash removal with periodic cleaning by countercurrent jet pulsing and as a catalyst for the abatement of gaseous pollutants (NOx, VOCs). The group proposed a flue-gas treatment comprising the following sequence: The first process step is dry scrubbing of the hot flue gas with Ca(OH)2, which reacts with SO2 to CaSO4. Then, NH3 is added to the flue gas, which reacts in the second process step with NOx on the surface of the catalytic filter. The catalytic filter also removes the solid CaSO4. In the last process step, a pre-heater transfers residual heat from the flue gas to the inlet air for the combustion process (Fig. 15.2). The theoretical advantages of this integrated system seem to be challenged by real world problems related to ash removal from the surface of the catalytic filter. Alvin et al. reported field experiences of the company Westinghouse Electric in 1998 [9]. Failure and performance limitations resulted from ash-related issues such as bridging, filter bowing, inner wall blinding, inner pore plugging, wedging of fines between the ceramic filter flange and metal holder mount, auto-ignition of char, and membrane debonding in alkali-laden systems. Nevertheless, in 2003 laboratory tests for

As Red Hat continues to work out the kinks in SELinux, there has been a tendency for users to see SELinux failures and just disable the entire SELinux service. However, a better course is to find out if SELinux is really stopping you from doing something that is unsafe. If it turns out to be a bug with SELinux, file a bug report and help make the service better. If you are enabling FTP, Web (HTTPD), DNS, NFS, NIS, or Samba services on your Fedora or RHEL system, you should consider leaving SELinux enabled and working with the settings from the Security Level Configuration window to configure those services. For information on SELinux that is specific Fedora, refer to this site:

To add a report title, follow these steps: 1. Right-click the left margin of the report and select Page Header to show the page header section. Be aware that once you have added content to a report section, the content is lost if you toggle that section off. 2. Add a textbox to the header from the Toolbox. 3. Type the report title and format the textbox. You may want the title to be dynamic based on the report content or parameters selected. This can be achieved by using an expression. Nearly all visual aspects of the textbox permit expressions too.

Now you have a new challenge to solve. Your script must create the individual month and day directories automatically, and know that if they already exist, they don t need to be created. As it turns out, this isn t as hard as it sounds! If you peruse the command line options for the mkdir command (see 3), you ll nd the -p command line option. This option allows you to create directories and subdirectories in a single command, plus the added bene t in that it doesn t produce an error message if the directory already exists. Perfect! We re now ready to create the archhourly script. Here s what it looks like:

(6.3-14)

public class DOMCheck { static public void main(String[] arg) { String filename = null; boolean validate = false; if(arg.length == 1) { filename = arg[0]; } else if(arg.length == 2) { if(!arg[0].equals("-v")) usage(); validate = true; filename = arg[1]; } else { usage(); } // Create a new factory to create parsers that will // be aware of namespaces and will validate or // not according to the flag setting. DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); dbf.setValidating(validate); dbf.setNamespaceAware(true); // Use the factory to create a parser (builder) and use // it to parse the document. try { DocumentBuilder builder = dbf.newDocumentBuilder(); builder.setErrorHandler(new MyErrorHandler()); InputSource is = new InputSource(filename); Document doc = builder.parse(is); } catch (SAXException e) { System.exit(1); } catch (ParserConfigurationException e) { System.err.println(e); System.exit(1); } catch (IOException e) { System.err.println(e); System.exit(1); } } private static void usage() { System.err.println("Usage: DOMCheck [-v] <filename>"); System.exit(1); } }

For the incorrect path, the corresponding metric is given by (14.86) with xi(n) , i = 1, 2 and (n) replaced by xi(n) , i = 1, 2, and (n) , respectively. Conditioned on a realization of the channel over the entire N -block observation, the PEP is given by P (X X|C) = Pr m (Y, X) > m Y, X |C = Pr m (Y, X) m Y, X > 0|C (14.87)
