Data storage and processing unit

The data storage and processing unit is placed at the roadside and in a protective cabinet. This unit is connected to the weight sensors, the vehicle classification sensor and the vehicle identification sensor. With the aid of software, it has the ability to present brief and analytical results. The data storage and processing unit also powers the WIM system the power is supplied by mains, rechargeable electric or solar batteries.

Even though the data storage and processing unit provides the user with all the information needed, there is usually a communication link with the user for data recovery/downloading from the storage/processing unit. The communication link may be a particularly designed data recovery device, a personal computer or a modem with a telemetry link. In the latter case, the data are sent and stored into an offsite user unit.

In addition to a powerful central processing unit, sufficient memory for program execution and raw data storage and manipulation is required. In order to acquire data from the detector, an analogue-to-digital converter... 

Highest quality in CTD salinity can be obtained only if the CTD is operated together with a rosette sampler (Fig. 3-5) for in situ calibration (see Section 3.6.3 for the calibration procedure and Section 3.6.4 for data processing). In these cases, a one-conductor cable serves to transfer CTD data from the underwater unit to the deck unit and a personal computer, and to control bottle closures by the operator. Recently, some manufacturers started to offer combined CTD-rosette sampler systems that have internal CTD data storage and that close bottles at prescribed pressure levels. Closing the bottles is controlled using the CTD s pressure sensor signal. 

If we define molecular computation as computation using molecules as data storage and/or processing units, the field is not limited to biomolecules. Indeed, the young science called supramolecular chemistry, which studies complex systems composed of synthetic molecules associated by weak interactions, has already produced some devices such as molecular switches, which may prove useful for future developments in computation, as we will see in Sect. 2.3. 

To determine maximum individual risk, generic frequency data are required for explosion events for Process Units 1 and 2. For Process Unit 1, incident data were available from the unit licenser identifying three explosions in approximately 15,000 operating years, for an explosion frequency of 2.0 x 10-4 per year. For Process Unit 2, a fault tree analysis of the nitrogen vessel brittle fracture event had been conducted as part of an unrelated project. That study concluded that the frequency of brittle fracture failure of the nitrogen vapor storage vessel was 5x10"4 per year. 

Figure 3.2 shows the flowsheet for the illustrative example. The data for the example is given in Table 3.1, where i, fc, and is are consecutive processing units, while d2,3 is a dedicated intermediate storage vessel between processing units and is. The time horizon of interest in this example is 9 h. 

According to TRI92 (1994), an estimated total of 250 pounds of di-ra-octylphthalate, amounting to about 2% of the total environmental release, was discharged to soils from manufacturing and processing facilities in the United States in 1992 (see Table 5-1). An estimated total additional 239,134 pounds were transferred to off-site waste treatment, storage, and disposal facilities. The TRI data listed in Table 5-1 should be used with caution since only certain types of facilities are required to report. This is not an exhaustive list. Furthermore, as noted above, the precise chemical identity of the reported releases is questionable. 

Some extensions are not essential for CC, but greatly improve its capabilities. Interfaces to a data storage device and to a hard copy unit are valuable. Some facility for data processing afterwards (baseline correction and peak area determination) is desirable.
