even by electrolyte stratification (the tendency of the heavier sulfuric acid to sink to the lower part of the cell) causing premature aging of the plates in that part. The only cure for these differences is to use a controlled overcharge, equalizing the characteristics of the cells by raising the charging voltage even higher after the battery is fully charged, and maintaining it at this level for several hours until the different cells again test identical. Obviously, this produces substantial gassing, so the precautions of a wellventilated area and no smoking definitely apply.

Imagine a solid object situated as in Fig. 8.2. Observe the axes in the diagram, and imagine that we slice the gure with slices that are vertical (i.e., that rise out of the x-y plane) and that are perpendicular to the x-axis (and parallel to the y-axis). Look at Fig. 8.3. Notice, in the gure, that the gure extends from x = a to x = b.

When fiber was first being used in the communications area, the technology was still developing. Multi mode fiber was used as a means of carrying communications signals on the glass more reliably. Multi mode, as the name implies, has multiple paths where the light can reach the end of the fiber. Single mode fiber, on the other hand, has only one path that the light can travel to get to the other end. Using a large piece (chunk) of pure glass, the developers extruded the fiber into much thinner glass strands. The multi mode fiber is the thicker glass by today s standards. The multi mode was developed in two different types, step index and graded index, both operating differently. Figure 28-3 is a representation of the multi mode fiber, using a step index mode. In this case, the glass is very thick at the center core (approximately 120 400 microns). The thickness of the glass is crucial to the passage of the light and the path used to get from one end to another. The step index is the thickest form of fiber; using the core of 120 400 microns thick, the light is both refracted and reflected inside the encased fiber. Because of the density of the glass, the center core refracts the light in different angles. At the same time, there is an outer cladding on the glass used to reflect the light into the center of the glass. This combination of refraction and reflection of the light, along with the density of the glass causes the light to take different paths (or bounces) to the end of the cable. Different light beams inserted into the fiber will take different lengths of path and therefore different timing periods to get to the end of the cable.

Here, absval will be assigned the value of val if val is zero or greater. If val is negative, then absval will be assigned the negative of that value (which yields a positive value). The same code written using the if-else structure would look like this:

execute. So it may take up to just under 2 minutes for a license to, once again, be available for check-out. In the previous example, a license was checked in at 21:01:05 with a linger time of 1 second. Its linger time should have expired at 21:01:06. Finally, at 21:01:40, the license server returned the license to the system. Now, no more licenses are checked out with identifier [ec26edf8].

Troubleshooting on the cloud is a different animal than in a traditional IT environment. Conventional troubleshooting tools and processes were developed around the hub-andspoke concept, with remote applications being the spokes to the centralized datacenter being the hub. But applications delivered from an off-site provider s datacenter defy traditional monitoring and require a different way to troubleshoot. At your organization, you have local visibility and control of applications. That control is much more limited with SaaS applications. In particular, it is difficult to distinguish SaaS traffic from other Internet usage going in and coming out of remote locations. IT staff do not have the local ability to determine whether the service is running or if the client has connectivity to the hosted application. Deep packet inspection (DPI) can deliver this granularity, but this technology is expensive to deploy throughout the enterprise.

If using direct mode connections to the data store, ODBC connectivity is required for proper operation of the IMA service. If ODBC issues are suspected, try the following: Verify that the database server is online. Verify the name of the DSN file the IMA service is using by looking in the registry at: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\IMA\DataSourceName. Attempt to connect to the database using the DSN file with an ODBC Test Utility (such as Oracle ODBC Test, DB2 Client Configuration Assistant test, or SQL Server ODBC Test).
