Computer input

In the analysis of vibration data there is often the need to transform the data from the time domain to the frequency domain or, in other words, to obtain a spectrum analysis of the vibration. The original and inexpensive system to obtain this analysis is the tuneable swept-filter analyzer. Because of inherent limitations of this system, this process, despite the use of automated sweep, is time-consuming when analyzing low frequencies. When the spectra data needs to be digitized for computer inputing, there are further limitations in capability of tuneable filter-analysis systems. 

The control, low-level, and high-level probes provide computer inputs and trigger the appropriate shutdown functions. The level is controlled over a range of about 2 mm. 

To use the ECES Program Builder, the user creates computer input as shown in Figure 1. The input consists of three parts The names of the components in the inlet stream to the flash unit, the names of the species present in all the outlet streams - vapor, aqueous, or solids, and the chemical and/or ionic equilibria of interest. From this input the Program Builder Block using the imbedded thermodynamic framework described earlier writes the model description as given in Figure 2. 

The Optimum Capability at PBR. Twenty-two air particulate samples were analyzed to again evaluate the analysis scheme. The total time for sample analysis averaged 4.5 hrs/sample. Two hrs of the total were used to check computer input and results. Up to 56 elements were reported. At this point an initial goal had been achieved. We could analyze 12 samples/wk in approximately 54 hrs. 

These values are required in this form for direct computer input. 

The computer input for such a conformational calculation consists of (1) the set of atomic coordinates, (2) the bonds about which rotation...

Time-Temperature Shift Characteristics. Temperature is a major environmental influence on viscoelastic pavement response. The VESYS IIM program can handle material properties as a function of temperature variations. The computer input command BETA relates the time-temperature shift factor, au to the temperature variable for the pavement materials. This relationship is given by ... 

The design must ensure that records generated by computer systems conform to their specified content. Records covering computer inputs, outputs, and data must be accurate. The computer system should also include built-in checks of the correctness of data that are entered and processed. Manual entry of critical data should be subjected to a confirmation check within the design that may be either manual or automatic. 

Table I gives the basic computer input data for the nine runs which were presented. Equilibrium moisture for AljOj and coke was taken as 0.04 and ceramics was taken as 0.01. The sphericity of the coke and ceramics was taken as 0.866.

In this example there are 5 species, 3 components, and 5 — 3=2 independent equations (mass laws). If equilibrium problems are solved by computer programs, the tableau often corresponds to the computer input (e.g., MICROQL see Westall, 1986). 

Individual responsible direct computer input identified at time of data input. 

There is no actual distinction being made between manually recorded data and data generated as direct computer input in IT systems, as has already been elaborated in section 7.3 (see page 195). Also the requirement that a study should be conducted in accordance with the study plan is self-evident and deserves no further discussion, especially since the measures to be taken if the study plan cannot be followed, the documenting of deviations and the issue of amendments, have been already described in full detail (see section 2.8, page 88).
