  • Automation is the use of control systems (such as numerical control, programmable logic control, and other industrial control systems), in concert with other applications of information technology (such as computer-aided technologies [CAD, CAM, CAx]), to control industrial machinery and processes, reducing the need for human intervention. In the scope of industrialization, automation is a step beyond mechanization.

  • A PLC or programmable controller is a computer based solid state device that controls industrial equipment and processes. Initially designed to perform the logic functions executed by relays, drum switches and mechanical timer/counters, it has been extended to analog control as well. A typical PLC system consists of a processor and an input/output system all mounted in a rack like system. The PLC system is a cost effective solution for applications with a high ratio of digital to analog points in a system.

  • Morphology change at tidal influent estuary is controlled by the net sediment transport rate of river and tidal transport, and variations in features (bathymetry, structures, etc.) where scour and shoaling take place. To examine river and tidal exchange sediment transport in a systematic way, we investigated sediment transportation at the Bach Dang estuary with a coupled tide, wave and sediment transport-morphology change numerical modeling system. Five simulations consisting of

  • This work contains numerous arguments, sketches, views, and theories and not all are central to the main thesis. I have tried to make the model of intellectual and intangible property presented in these pages accessible while maintaining a fair amount of rigor and depth. I thus skirt the line of boring the expert and overwhelming the novice. My hope is that I have done neither.

  • The time is gone when machines, controls, and drives were ‘‘add-ons,’’ as shown in Figure 1. Early machines used add-on drives. These drives had one thing in common: There was no interaction among the control, drive, and machine. To a large extent these machines were open loop. Today’s numerically controlled machines are tightly integrated machine systems. There is a great deal of interaction between the machine, drive, and control. It is this interaction that results in problems with stability, surface finish on the work part, and accuracy.
