High experiments

Microfiltration and ultrafiltration have recently been introduced for the removal of particles down to any desired size. Their capital cost is relatively high. Experience with them is limited, and a short trial with a small-scale pilot element is advisable. Prediction of full-scale performance from such trials is normally quite reliable. 

Breaking of the N-O bond by the surface of rhodium is the most essential step in the catalytic reduction of NO. Although rhodium is sufficiently reactive to achieve this (even without promoters), dissociation can nevertheless be severely impeded if the surface coverage is too high. Experiments using static secondary ion mass spectrometry have clearly demonstrated this [52]. 

This type of reaction scheme is fairly common in organic synthesis. If the second reaction is faster than the first reaction ( i< 2)j h is difficult to stop the reaction at the first stage. P2 is formed as a major product. If the first reaction is faster than the second reaction ki > 2) there is a chance to obtain PI selectively. When one equivalent of A relative to B is used, PI should be obtained selectively. In other words, when the stoichiometric ratio of two reaction components is approximately unity (A/B = 1), the selectivity for the primary product PI should be high. Experiments,... 

High experience level with plants and methods. 

In addition, if your company bids for jobs, a high experience rating can cost you contract work if, as part of the bid, the company requests information about your experience modifier. If it s too high, it may see your employees as a high risk, and you could lose the bid because of the following ... 

There is no sharp dividing line between "slightly" supercritical and "highly" supercritical. Experience has shown, however, that for most practical purposes the dividing line is in the region T/T, 1.8. Using this criterion as a guide, it... 

Our experiences with the software developed within the ANDES project have shown that CBR is a helpful methodology for use in the interpretation of NDT data from field inspections. Because CBR systems can adapt to new situations they can cope with inspection of varying constructions in varying conditions. However, because CBR systems learn from classifications made by the operator this means that they will not be very useful for completely automatic interpretation. Fortunately, most of the NDT inspection requires the presence of an operator because of the required high reliability. 

Eddy-current non-destructive evaluation is widely used in the aerospace and nuclear power industries for the detection and characterisation of defects in metal components. The ability to predict the probe response to various types of defect is highly valuable since it enables the influence of particular parameters to be studied without recourse to costly and time consuming experiments. The solution of forward problems is also essential in the process of inverting experimental data. 

As probes must be manufactured individually for each different tube type, the probe development is an important factor for the economic use of the method. The classical procedure of probe development is a combination of experience and experiment. The new probe design is based on the experience with already manufactured probes. For an evaluation of the new design the probe must be manufactured. If the probe design is complicated, for example due to dual exciter coil arrangement or segmented differential detector coil systems, the costs of the development can be very high. Therefore a method for the pre-calculation of the probe performance is extremely useful. 

During the past few years radioscopy has established itself in many fields that demand instant evaluation and a high degree of automation, as is the case in serial inspection. Furthermore, user experience has clearly shown that inspection costs can be considerably reduced by this technique. 

High-current betatrons experiments confirm the wide practical possibilities of use of these installations for radiative control of the articles and materials with big thickness. 

A tube manufacturer wanted to investigate the possibility for on-line measurement, calculation and presentation of eccentricity values on aluminum tubes when drawn at high velocities. Based on our experience from development of tube inspection systems [1, 2] for off-line inspection of precision tubes, a project was formulated. The main specifications for the tube manufacturing are summarized below ... 

Critical to the successtlil completion of this process are the software tools required to store and analyse the inspection and related data. This is a major task and to achieve this OIS has produced, in conjunction with a major specialist technical software provider, the Asset Condition Evaluation Tool (Acet). Acet is a comprehensive suite of programs which draws on the extensive experience of engineers working in this field for many years, to provide a readily usable and highly auditable package for this application. 

The numerical illustration given above is so highly idealized that any agreement with experiment could hardly be more than coincidental. A number of caveats have been mentioned, including the inadequacies of theoretical calculations, the various surface distortions and reconstructions expected, surface...
