Dynamic DNS (DDNS) enables a Windows Server 2008 DNS server to automatically update resource records for clients if their host names or IP addresses change. Host name changes can occur when the remote computer changes computer name or becomes a member of another domain (which implicitly changes its FQDN). The use of DHCP is another argument for DDNS. As DHCP leases expire, a client computer s address can, and is likely to, change. This makes maintaining accurate DNS records for hosts on the network that use DHCP for address allocation dif cult. DDNS resolves the problem. DDNS functions through a client-server mechanism. Windows 2000, 2003, and XP DHCP clients support DDNS and can directly request that a Windows Server 2008 DNS server update their host resource (A) records whenever the clients IP addresses or host names change. Windows Server 2008 DHCP servers can also submit requests on behalf of clients, although a DHCP server can request an update to both the clients host and pointer (PTR) records. A Windows Server 2008 DHCP server also can act as a proxy for non-DDNS-capable DHCP clients to perform dynamic DNS updates. A Windows Server 2008 DHCP server can, for example, perform updates for Windows 9x and Windows NT clients, which do not natively support Dynamic DNS and, therefore, cannot submit requests to either the DHCP server or DNS server to update their resource records. Figure 5-12 shows how DHCP and DNS interact.

where R = E{u uT } is the correlation matrix of the received signal, and p = E{u ci } the crossi i i correlation between the received signal and the transmit signal. Considering the frequency domain, concatenation of the noise-whitening lter with the equalizer E(z) has the transfer function: E(z) = 1 (z) +

There are other options available for sending faxes from your computer. We like eFax, by j2 Global Communications (www.efax.com), as a fax service. This is both a free and fee-based service. If you use the free service, you are assigned a fax number and can receive faxes in either an image or PDF format. When someone faxes you, you receive an e-mail with the fax as a file attachment. The free service allows a limited number of incoming fax pages. If you opt for the fee-based service like we do, you can pick your fax number from virtually anywhere in the world. You can receive faxes, but you can also send faxes from either a desktop application or through the eFax Web site. This service has been very reliable for us, especially when doing business outside of the United States. If you are a SOHO user, you may want to consider this very cost-effective option!

An AMPS Overhead Parameter message (OPM) consists of several words. Figure 12.4-1 shows the most important OPM words [6]. All messages include parameter words PW1 and PW2. The other words are included only when necessary. In all OPM words, the type eld (T1T2) is set to 11. This distinguishes these words from words of mobile control messages on FOCC. The overhead (OHD) eld identi es the word type: OPM Word Type First parameter word Second parameter word Acronym PW1 PW2 OHD 110 111

space between the pole-pieces for other applications needing high tilt or an exotic specimen holder and resolution. Ultra-high-resolution microscopes can now safely be tted with an EDX system. Besides hardware re nements, the 1970s and 1980s were also rich in software developments, not least in the eld of quantitative X-ray microanalysis. It is probably fair to say that by the end of the 1980s EDX had matured into a relatively easy-touse technique, compatible with most commercially available TEMs. Single point analysis, line scans and X-ray maps were by then relatively straightforward to obtain. If one criticism is to be voiced, it is the fact that commercially available software packages are clearly derived from their counterparts developed for scanning electron microscopy analysing bulk samples instead of thin specimens. Apart from the sometimes-erroneous terminology, many non-expert users have been misled by the quantitative analysis outputs that industry wide are given with an incredible precision of two digits after the decimal point of atomic or weight percentages. Systematic errors and ill-de ned correction schemes for absorption and uorescence have led to erroneous results. The 1990s have not really addressed this issue but at the same time a clear shift from quantitative analysis back to qualitative analysis was noticeable albeit in a totally different ballgame than in the early days.

Doing so produces a pop-up menu like the one shown in Figure 10-17.

The result of using this function means you have much more data at your fingertips, but it takes much more math and logic to build. The result is shown in Listing 20.5.
