Graphics hard copy

Operator control stations. These typically consist of color graphics monitors with special keyboards, in addition to a conventional alphanumeric keyboard, containing keys to perform dedicated functions. Operators may supervise and control processes from these stations. A control station may contain a number of printers for alarm logging, report printing, or hard-copying process graphics. 

CADD, a part of CAD, is the computer-assisted generation of working drawings and other documents. The CADD user generates graphics by interactive communication with the computer. The graphics are displayed on a video terminal and can be converted into hard copy by a printer or plotter.

Proposals often include full-color graphics to elucidate important concepts. Color graphics should also make sense in gray scale, in case reviewers print out a hard copy. 

In addition MOLY contains a large number of utility programs which allow for efficient molecular storage, retrieval, orientation and display. The system is written entirely in FORTRAN and executes on an IBM 370/158 under the MVS operating system and the TSO time-sharing system. User interaction is via a Tektronix 4006 or 4010 graphics terminal. Hard copy capabilities are provided via Tektronix photocopiers as well as a Calcomp digital plotter. 

Two monitors are used to visually examine the spectrum in real time as it is collected and a graphics terminal is used to examine the spectrum once it has been subjected to image processing. A digital plotter provides hard copies of processed spectra. 

When the reaction mechanism is completely entered, ChLI has all the information needed to create a symbolic matrix to pass along to MLI, as well as a molecule and atom list for mass balance calculation, graphic or printed identification, etc. In particular, it can create a text-processor e.g. TROFF, T jX) representation for hard copy output and documentation. The reaction matrix is also available to other modules, in particular the display module, for the creation of flowcharts and other designs for the most effective presentation of results.

Because of the complexity and scope of the problem, trilateral graphic analysis was selected as a method to document the artifact and to evaluate potential consolidations. Three-dimensional mapping was digitized for hard copy and electronic manipulation (Figure 25). 

Without convenient terminals and hard-copy devices, the situation for the chemist would be little better than the early days of chemical graphics, when even the largest of companies would only invest in a few expensive workstations and chemists would have to leave their laboratories to run a search. The real turning point that made the computer revolution happen was that systems were beginning to be hardware-independent and prices were continually decreasing in the competitive computer market. 

Meters with calibrated scales were used for readout in early AA instruments. Nowadays, digital displays and graphical presentation of signals on the screen of video display units are used. Analytical results can be made as a hard copy on a chart recorder, a printer, or a plotter. A typical hard copy of the analytical results is shown in Figure 27. 

This chapter was not written for (the few) experts in the field of organometaiiic thermochemistry. The contents selected for this overview had in mind those chemists who need to use thermochemical values to predict stability or reactivity and may welcome some clear guidelines about the appropriate use of data. Another important choice was concerned with the amount of data to be included in the form of tables or graphic representations. Hard copy databases, of any sort, are clearly old-fashioned resources. They have been gradually replaced by electronic databases, enabling much faster searches and allowing to keep the contents permanently updated (which is particularly important for thermochemical databases see below). It was, therefore, decided to include a minimum of data and use the available space to review concepts, experimental methodologies, available databases, empirical estimation schemes, and to discuss some important applications. 

The library of known 3-D structures is on a VAXll/750 which did not even have a fioating point accelerator at first. The dynamic graphical system uses a PS300 with hard copy facilities (laser printer and Tektronix plotter). 

The objective of this task Is to develop a comprehensive computer data base containing the experimental data on properties of ceramic materials generated In the overall effort, This computer system is intended to provide a convenient and efficient mechanism for the compilation and dissemination of the large amounts of data involved. The data base will be made available In electronic form to all project participants. In addition, periodic hard copy summaries of the data, Including graphical representation and tabulation of raw data, will be Issued to provide convenient information sources for project participants. 

Accompanying this text is a Solutions Manual written by Catherine E. Housecroft, and there is an accompanying Website with multiple choice questions and rotatable structures based on the graphics in the hard-copy text. The site can be accessed from www.pearsoned.co.uk/housecroft. 

If a graphical display is reqnired as a function of a measurement system, a factor that must be considered is whether the record can be temporary or if it must be permanent. If the latter is required, either photographic techniques or some form of hard-copy writing system must be used. The filing of quantities of recorded data can create reference and storage problems, hence the use of temporary records is often desirable. Examples of this are virtual instalments (Fig. 11) and the storage oscilloscope (Section III.B).
