This application controls a certain aspect of an automotive powertrain system. Due to the real-time control nature of this application and the number of concurrent timing operations, the synthesized version of the chip was implemented with ten concurrent processes. A generic diagram illustrating the flavor of the interprocess communication on this chip is shown in Figure 4, and the synthesized chip layout is shown in Figure 5. [Pg.320]

Since the motor s fixed parameters can now be varied to suit a particular load requirement, there is no need to pre-match a motor with the load. Now any motor can be set to achieve the required characteristics to match with the load and its process needs. Full-rated torque (TJ at zero speed (during start) should be able to pick up most of the loads smoothly and softly. Where, however, a higher 7 s, than is necessary, a voltage boost can also be provided during a start to meet this requirement. (See also Section 6.16.1 on soft starting.) The application of phasor (vector) control in the speed control of an a.c. motor is shown in a block diagram in Figure 6.12. [Pg.108]

Operational sequence diagrams are flcw-charting techniques that represent any sequence of control movements and information collection activities that are executed in order to perform a task. Various activities in the diagram are represented with a symbolic notation, supported where necessary by a text description. For the majority of simple applications, OSDs assume a linear flow drawn from top to bottom with a limited degree of branching and looping. The symbols used are usually tailored to fit the type of task being studied and its level of analysis. [Pg.172]

Over the years the original Evans diagrams have been modified by various workers who have replaced the linear E-I curves by curves that provide a more fundamental representation of the electrode kinetics of the anodic and cathodic processes constituting a corrosion reaction (see Fig. 1.26). This has been possible partly by the application of electrochemical theory and partly by the development of newer experimental techniques. Thus the cathodic curve is plotted so that it shows whether activation-controlled charge transfer (equation 1.70) or mass transfer (equation 1.74) is rate determining. In addition, the potentiostat (see Section 20.2) has provided... [Pg.94]

The complexity of the systems to be protected and the variety of techniques available for cathodic protection are in direct contrast to the simplicity of the principles involved, and, at present the application of this method of corrosion control remains more of an art than a science. However, as shown by the potential-pH diagrams, the lowering of the potential of a metal into the region of immunity is one of the two fundamental methods of corrosion control. [Pg.199]

Figure 9 shows a typical application of a block diagram to identify the operation of a temperature control system for lubricating oil. (A) in Figure 9 shows a schematic diagram of the lube oil cooler and its associated temperature control system. [Pg.118]

It is also necessary for a number of heat treatments (annealing, quenching, etc.) which have possibly to be defined according to the aspect of the phase diagram of the materials involved. A variety of methods and instruments are used in order to achieve and control the selected temperatures. A selection of these will be presented in the following, either directly or through their applications. [Pg.532]

A final caveat that must be applied to phase diagrams determined using DFT calculations (or any other method) is that not all physically interesting phenomena occur at equilibrium. In situations where chemical reactions occur in an open system, as is the case in practical applications of catalysis, it is possible to have systems that are at steady state but are not at thermodynamic equilibrium. To perform any detailed analysis of this kind of situation, information must be collected on the rates of the microscopic processes that control the system. The Further Reading section gives a recent example of combining DFT calculations and kinetic Monte Carlo calculations to tackle this issue. [Pg.175]

A further step in the "activation" of the chemical species present might result in the active migration of silica in solution. Then a diagram such as that of Figure 46c would be applicable. In this system the pH is still controlled by the mineral species present, all of which are stable at some a-alkali, a-Si values. A further intensive variable can be conceived as being due to the dissociation of H O and considering the activity of the H+.ion in solution. This is the most commonly used type of representation, as mentioned previously. Here only one-phase... [Pg.166]
