Wired-program computers

This problem can be partially resolved by using a digital computer in which integration is performed after the spectrum is stored in the memory. Some careful base-line correction can be made before trial integration. The Fabri-tek 1070 instrument computers are hard-wired programmed for such operation, and a thorough examination performed in our laboratory indicated that a normal integration uncertainty of less than 1% can be obtained with this computer. [Pg.47]

In between the computational capabilities of the minicomputer and the rigidity of the hard-wired controller lies the microprocessor. These instruments emulate the hard-wired programs of the controller via a read-only memory (ROM). This memory is preprogrammed by the manufacturer rather than the operator. To gain some... [Pg.248]

The numerical method of solving the model using computer tools does not require the explicit form of the differential equation to be used except to understand the terms which need to be entered into the program. The heater and the barrel were modeled as layers of materials with varying thermal characteristics. The energy supplied was represented as a heat generation term qg) in a resistance wire material. Equation 1... [Pg.493]

Massive quantities of wiring documentation describing the connections to the RTU s were transposed into configuration data files available to the computer. Before CPC start-up, a detailed system checkout procedure was implemented to conflrm the accuracy of the data files. A preventive maintenance program was initiated as soon as the system was operational to check metering for proper calibration and reliability on a routine basis. [Pg.54]

Subject Update on progress Dr. B This week, I programmed the computer to automaticaily calculate aH the relevant physical data for my reactions. I ve assembled a template to create a virtual notebook page, complete with structures, tables, references, and a system that automatically y suitable for pubUcat based on output parai I ve wired the laboratd directly to the departn LAN arKi written a c retrieval/trs... [Pg.4]

At some point a company may decide that a more automated system is desired and this is usually a call-out type system. This system typically consists of a computer which is wired either into each chamber s integral alarm system or equipped with its own independent probes. A list of phone numbers is programmed into the computer and when a chamber exceeds its tolerance for a given period of time, the computer automatically starts calling these numbers. The phone numbers might be those of a third party contractor or internal employees. This type of system promotes the quickest response to a chamber excursion. Some of these systems will allow you to call in to check on the chamber conditions. These systems should undergo then-own qualification when installed. [Pg.295]

Consider next the finite x infinite array shown in Fig. 1.2. It consists, like the infinite x infinite case in Fig. 1.1, of columns that are infinite in the Z direction, however, there is only a finite number of these columns in the X direction. Such arrays have been investigated by numerous researchers [4-23]—in particular, by Usoff, who wrote the computer program SPLAT (Scattering fi om a Periodic Linear Array of Thin wire elements) as part of his doctoral dissertation in 1993 [24, 25]. [Pg.1]

The finite array will be modeled by a finite number of infinitely long column arrays (also called stick arrays see Fig. 4.1). This approach has been widely used by several researchers [74-80]. One of them, Usoff, wrote as part of his dissertation [24] the computer program Scattering fi om a Periodic Array of Thin Wire Elements (SPLAT). The excitation can be either in the form of an incident plane wave propagating in the direction 5 = + ysy + zsz (passive case). Or... [Pg.85]

Game Programming and Animation. Basic and integral parts of both the video game and the motion-picture industry are described by the terms polygon, wire frame, motion capture, and computer-generated imagery (CGI). Motion capture uses a series of reference points attached to an actor s body. The... [Pg.906]
