Dimensioning operating system

This paper describes the development of a novel system for improving the quality of information provided by manual ultrasonic examination of welds, while retaining the flexibility of the human operator to apply the techniques to components of a wide range of geometries and dimensions. The system, known as CamuS (Computer Aided Manual UltraSonics) provides assistance to the manual operator in two separate areas ... 

The oranges were washed, chopped in a meat mincer and homogenised by a Fryma mill. Water (0.6 volumes) were added before the slurry was heat treated by steam injection at 100°C for 2 minutes. The enzyme treatment was carried out for 1 hour at 40°C with 10 lU/g slurry of PME and 25 pg enzyme protein/g slurry of the other enzymes for each of the enzymes. The gelated orange slurry were treated at 85°C for 3 minutes to inactivate the enzymes before the strength of the gel was measured by a SMS TeJrture Analyser TA-XT2 (Stable Micro Systems, XT. RA Dimensions, Operations Manual versions) by compression analysis using a flat cylinder (20 mm dia.) with a speed of 2 mm/s. The force to provide a 20% compression was recorded. 

In the heart-cutting mode of operation, one or several discrete zones are collected from the first-dimension column and reinjected into the second-dimension separation system. The resulting data are one or more individual one-dimensional datasets and are useful for resolving fused peaks from specific region(s) of the fust-dimension separation system. An example of zone reinjection is shown in Fig. 5.1 clearly, the second column provides the selectivity for the three peaks that the first column did not have. 

Another study (Bedani et al., 2006) starts from the multidimensional sampling theory (Murphy et al., 1998a), which is discussed in Chapter 2. This sampling theory states that one needs to sample the first dimension separation system at least three to four times per peak width for maximum resolution. Bedani et al. then equate the second-dimension total analysis time to the first-dimension narrowest peak standard deviation. This defines the second-dimension operational parameters. All other parameters can be derived from this balance and Bedani s study goes through this and discusses how the rest of these variables are obtained. 

Others have examined the necessary parameters that should be optimized to make the two-dimensional separation operate within the context of the columns that are chosen for the unique separation applications that are being developed. This is true for most of the applications shown in this book. However, one of the common themes here is that it is often necessary to slow down the first-dimension separation system in a 2DLC system. If one does not slow down the first dimension, another approach is to speed up the second dimension so that the whole analysis is not gated by the time of the second dimension. Recently, this has been the motivation behind the very fast second-dimension systems, such as Carr and coworker s fast gradient reversed-phase liquid chromatography (RPLC) second dimension systems, which operate at elevated temperatures (Stoll et al., 2006, 2007). Having a fast second dimension makes CE an attractive technique, especially with fast gating methods, which are discussed in Chapter 5. However, these are specialized for specific applications and may require method development techniques specific to CE. 

Most of the frequently used comprehensive 2D LC systems employ a microbore HPLC column in the first dimension, operated at low flow rate, both under isocratic and gradient conditions. This enables the transfer of fractions of small volume via the multiport valve equipped with two identical... 

Suppose that two sintering systems, S and B, are identical in all aspects except their size.15 Each length dimension of system B is A times as large as the corresponding dimension of system S. Under identical conditions and provided that the same sintering mechanism is operative, the ratio of sintering rates can be determined from the relative sizes of the specimens. 

The software for the model 900 SECM runs on the Windows operating system with a Pentium class machine. The software provides all the controls necessary for positioning the probe in three dimensions and setting parameters for electrochemical experiments. The software also supports a wide range of electrochemical experiments, graphical displays, data processing,...

It has to be emphasized that the operating systems of a plant are dimensioned by the same procedure with both approaches. Requirements for the systems are specified, for example, the quantity of heat to be extracted from a reactor for an exothermal reaction. The corresponding calculations are performed using mathematical models reflecting the underlying laws of nature. Results in this case may be, for example, the power of the coolant pump, the necessary surface for heat transfer, or the pipe diameter. This procedure is called deterministic. 

In the course of the Phase B shared-cost action (SCAs) exercise for the dimensioning of Phebus-FP /1,2/ it became clear that while a wide variety of source term codes are in use in Europe, intercomparison of their predictions is rendered difficult by the different environments in which they run, meaning different computers, different operating systems, different input and output formats etc. The codes and modules nevertheless represent the state of the art in source term predictions, and... 

Templates for each of the joint configurations are stored within the system. The operator selects one of the templates, and is provided with a visual representation, as shown in Figure 3, on which he can alter the Joint dimensions and weld geometry to match those of the item to be examined any ae-cess restrictions can also be defined. Using information from a database of available probes, along with the examination level required, ProcGen then calculates the set of scans required (see Figure 4). 

The coin-tap test is a widely used teclinique on thin filament winded beams for detection of disbonded and delaminated areas. However, since the sensitivity of this teclinique depends not only on the operator but also on the thickness of the inspected component, the coin-tap testing technique is most sensitive to defects positioned near the surface of the laminate. Therefore, it was decided to constructed a new scaimer for automated ultrasonic inspection of filament winded beams. A complete test rig illustrated in figure 6 was constructed in order to reduce the scanning time. While the beam rotates the probe is moved from one end to the other of the beam. When the scarming is complete it is saved on diskette and can then be evaluated on a PC. The scanner is controlled by the P-scan system, which enables the results to be presented in three dimensions (Top, Side and End view).
