illustrates two ways that a named iterator can be used to obtain elements. One enumerates a range of elements given the endpoints. The other enumerates the elements beginning at the start of the sequence and ending at the specified stopping point.

it should be obvious that a well-maintained system would give us fewer problems when activating the reverse system. 7.231 One of the simplest and most valuable tests is a system endlevel test. To use such a test program, ground-level test points should be installed by running a drop from a tap connected near the last line extender (LE) ampli er at one of the system ends. If the cable system has a skeleton plant diagram, the end points where tests should be performed will be obvious. A sample of such a diagram is shown in Figure 7-13. Systems using long cascades of trunk ampli ers can exhibit poor system atness responses due to the ampli ers characteristic signature. A slight dip, for example, in the mid-band can develop to a deep valley down the cascade. In the past, the ampli er manufacturers did not manufacture the ampli ers to tight tolerances, so the dips and small peaks varied differently, causing the effects to cancel. End-level tests on the system s carriers spaced throughout the spectrum will indicate any atness problems before they become critical. Some systems elect to take end-level tests monthly and some bimonthly. Tracking the measured values through the seasons provides information on how well the thermal compensation and automatic gain circuits (AGC) are operating. These measurements are easily made with most present state-of-the-art signal-level meters with a keypad channel entry. Some enable the instrument to step through the programmed channels to be tested by the touch of a button. Analyzing the data can be made easier by having the data recorded on a disk and having analysis software provide graphical plots on histogram charts of signallevel variations. 7.232 Leakage testing is the other required maintenance program. A good leakage program aids a system in keeping the plant tight, keeping leakage, ingress, and noise to a minimum. Often a system will nd connector problems before upstream data service problems develop. Although the FCC requires leakage tests to be made using a test dipole, leakage test equipment sets made for nding system leaks are more accurate, easier, and faster to use. A calibrated leak can be made near the maintenance department and activated when the install and service trucks are leaving in the morning. White lines indicating the 10-ft distance and the drive-through lane can be painted on the parking lot. The trucks passing through can activate their equipment and check instrument calibration on their way out to work. After leaving, the equipment generating the calibration leak signal can be turned off. Continual testing for leaks

NPN transistor. Transistors are usually explained in terms of electrons and holes. I prefer a water analogy, which will serve our purposes well enough. Figure 14.1 shows the three terminals of the NPN transistor: base, collector, and emitter. The small arrows show the direction of current ow in the leads: IB, IC and IE. Note that the arrow in the emitter lead serves the same purposes and distinguishes the NPN from the PNP transistor. The transistor is constructed like a pair of diodes connected back-to-back. Current IB will ow from the base to the emitter, in the direction shown, whenever the base is at a higher voltage than the emitter. Now the analogy the base acts like a valve in the collector-to-emitter waterpipe. A small change in IB results in a large change in IC and IE. The ratio of current changes is called the forward current gain:

strOp = so.RemoveSpaces; str = strOp("This is a test."); Console.WriteLine("Resulting string: " + str); Console.WriteLine(); strOp = so.Reverse; str = strOp("This is a test."); Console.WriteLine("Resulting string: " + str); } }

Organizations increasingly operate globally. As a result, their overseas activities, international business partners, and foreign customers may be subject to different laws and regulations. These organizations need to make certain that they are in full compliance with these non-U.S. legal norms, such as laws of a foreign nation-state or an institutional framework such as the European Union. These international law considerations are all the more important for organizations managing, processing, and using information across national boundaries. They are discussed in the following sections, with special attention given to the European Union (E.U.) Privacy Directive.

Although we often correlate complexity with the number of users, even small deployments can be complex in nature, and thus benefit from XenApp. Here are some typical challenges the administrator of a complex environment face: The need to provide instant, easy, and secure access to applications across the organization Meeting the end-user demand for a consistent access experience to information
