The most familiar display is a television or visual display unit associated with a computer. Both are based on the mature cathode ray tube (CRT) technology, whereby an electron beam selectively activates red, green, and blue (RGB) inorganic phosphors. It is an emissive technology and therefore produces bright images. 

Results can be delivered by means of a large variety of peripherals fitted to the computer output. The commonest of such peripherals Is no doubt the visual display unit (VDU), usually a cathode ray tube (CRT) similar to a TV set, indirectly linked to the keyboard to receive the information typed in. Printers and plotters are probably the most important result display devices with a view to automation as the results, whether numbers, text or graphs, are permanently printed on paper and are recorded after each analysis without the need for the operator s presence. 

Digital read-out devices also are used in atomic absorption spectroscopy. The digital voltmeter frequently uses a nixie tube display. These devices call for the operator to record a visually displayed number. 

Liquid crystals, commonly referred to as the fourth state of matter, are materials which are intermediate in character between the solid and liquid states. Unlike normal isotropic liquids, they show some time-averaged positional orientation of the molecules, but they retain many of the properties of liquids, such as the ability to flow. In recent decades, liquid crystals have played an increasingly important part in our lives. Probably their most familiar application is in the information displays which provide the visual interface with microprocessor-controlled instrumentation. Liquid crystal displays have superseded more traditional display technology, such as light-emitting diodes and cathode ray tubes, for many appliances principally because of the advantages of visual appeal, low power consumption, and their ability to facilitate the miniaturisation of devices into which they are incorporated. They are encoun-... 

The pump is switched on (without flow) and the instrument (pump head, displays, etc.) as well as the connecting fittings and tubes are checked visually. In the case of complaint the necessary measures are planned and documented. 

Flat panel displays are a necessary prerequisite for the full visual availability of information. After development of passive matrix displays used in digital watches, calculators [160] and portable computers, intensive work started in the development of large-area, full colour active matrix liquid crystal displays with high resolution. At the present time, LCDs are a major market force rivaling cathode ray tubes [157a],... 

Now you are ready to submit the molecule for geometry optimization via calc-queue-add and to visualize the results in the results calc-result section, as described above. To be able to determine which conformer was optimized, you may choose the wireframe or tubes render options, which you will find in molecule-views-view-render, you may also want to deactivate the display of hydrogen atoms in molecule-views. 

Zone Temperature Monitoring Systems were Installed under Project OCI-666 at the six old reactors to provide safety circuit action for "hotspot control. This system Is composed of RTD s (resistance temperature detectors) controllers, and a visual readout display. The RTD s measure the temperature of the outlet water from the center process tube of a 3 by 3 tube cell or zone. A special wye fitting was installed between the spiral connector and the Parker fitting to house the RTD. 

Based on this elueidation, an energy-minimized moleeular model ean be ealeulated. Fig. 11 displays the tube, ball-and-stiek and the spaee-filling model of aeanthifolin obtained as a result of this ealeulation by means of eommereial software in order to visualize the angle relations and shape of the moleeule.
