Figures 12.11 and 12.12 show for an open-track spring-loaded system a plot of the maximum windup ratio bm versus h, with Qm as a varying parameter for the harmonic cam curve and for the cycloidal cam curve, respectively. Qm is a measure of the degree of severity of the drive shaft windup. For Qm = 0, there is no windup in the drive train since the drive train vibration is caused by the accelerating and decelerating torques required to move the follower mass through its rise. Thus, the greater Qm, the greater is this forcing function. The jump line indicates the limiting condition in which the vibration model is invalid. From these gures, one can see that increasing the value of the frequency ratio h and decreasing the value of the re ected inertia ratio Qm imply stiffer systems, thus reducing the drive system windup effect. Furthermore, the harmonic rise produces lower drive shaft windup than the cycloidal curve cam. 12.4.2.2 Closed-Track Cam System. Next let us consider the closed-track cam follower system, Fig. 12.13. This system has special physical phenomena when compared to the open-track system presented earlier. In the closed-track system we see The torsional vibration and the response frequency are two times the basic speed of the input. The follower and cam are constrained together and re ect and exchange their rotation energy throughout the whole cycle. Equation (12.14) is modi ed by the elimination of the term, krxx = 0, since there is no return spring that gives the second-degree vibration equation for the closed-track camfollower system ( Ic + mx 2 )q c + mx x q c2 + ksq c = ksq i (t ).

This program displays the number 100. While the preceding example is trivial in fact, no one would actually use the this pointer in this way the following section shows one reason why the this pointer is so important.

The ICollection interface is the foundation upon which all non-generic collections are built. It declares the core methods and properties that all non-generic collections will have. It also inherits the IEnumerable interface. ICollection defines the following properties:

You should be familiar with the PDU terms used at the various OSI Reference Model layers: segment: transport; packet or datagram: network; frame: data link; and bits: physical. Also be able to describe how devices communicate with others at the various layers: what layer 2 or layer 3 addresses are used between various devices from the source to the destination. Remember that MAC addresses can change from link to link, but layer 3 addresses, such as TCP/IP addresses, typically do not.

The Obsolete attribute, which is short for System.ObsoleteAttribute, lets you mark a program element as obsolete. It has this general form: [Obsolete( message )] Here, message is displayed when that program element is compiled. Here is a short example:

With SNMP-based systems, the agent processes events and sends messages with little to no filtering or processing on the local system. This is acceptable because SNMP messages are typically small and not likely to flood the network. In systems with more intelligent agents, where much more detailed information can be collected, the agent has the added task of collating or summarizing the data before sending it to the manager. Otherwise, the added traffic caused by unsummarized messages could cause a bandwidth utilization problem.

When working with complex drawings, the View Manager provides a quick way of saving and recalling views.

When separations are selected to print, the ink colors used in your document are listed at the bottom of the Separations tab. Each ink includes options for choosing if and how they will be printed. You ll see a series of columns that show how each ink color is set to print, with its color reference, ink color name, screen frequency, screen angle, and overprint options. The inks will ultimately print in order from top to bottom as you see them on the list. First, don t change the frequency or line angle unless you re a professional the default values are standard among the printing community. To change the Frequency and/or Angle of a specific ink color, click directly on the value and then enter a new value. To change overprinting properties of a specific ink color, click directly on the overprint symbols for text and/or graphic objects to toggle their state. The following list explains what each of these options controls:
