Inspection Sequence

The virtual transducer can be placed in a specific location on the test object surface, it can be moved along a path (e.g. a robot scanning path generated off-line or a path resulting from a real inspection sequence) or it can be moved along the surface, dynamically updating the ultrasonic sound propagation in the material. [Pg.871]

It is difficult to check all items after each manufacturing process. Therefore, an appropriate inspection sequence in the total manufacturing flow should be designed. [Pg.1591]

The selection and sequence of tubes to be inspected are known at the start of a measurement campaign. After a tube has been measured, the reference is transmitted to the pre-fetching module. This latest can, through an anticipation window, copies a certain number of records on the hard disk. [Pg.1025]

Generalizing on [12], we construct a loop by using a sequence of three elementary reactions. It is emphasized that the reactions comprising the loop must be elementary ones There should not be any other spin pairing combination that connects two anchors. This ensures that the loop in question is indeed the smallest possible one. Inspection of the loops depicted in Figure 4 shows that the H3 and H4 systems are entirely analogous. We include the H3 system in order to introduce the coordinates spanning the plane in which the loop lies, and as a prototype of all three-electron systems. [Pg.337]

Inspection of the values for the structure elements and their contribution to the heats of formation again allows interpretation The B-terms correspond to the energies to break these bonds, and a sequence of three carbon atoms introduces stabihty into an alkane whereas the arrangement of three carbon atoms around a central carbon atom leads to the destabilization of an alkane. [Pg.324]

The review should emphasize developing an understanding of the processing sequence, the equipment, the equipment plot, the operating conditions, instrument and sample locations, the control decisions, and the operators perspectives. Wmle the preparation effort may be less for those who have been responsible for the unit for a long period of time, the purpose of the test requires that the types and locations of the measurements be different from those typically recorded and typically used. The condition of these locations must be inspected. Operating specifications may be different. Therefore, refreshment is always necessaiy... [Pg.2552]

The relationships between the importance measures is based on the assumption that the systems are not reconfigured in response to a component outage. If this is done, the basic definition of the importance measure is still valid but there is not such a simple relationship. Disregarding this complication, some interpretations of the importances may be made. The Bimbaum Importance is the risk that results when the i-th system has failed (i.e., it is the A, term in Equation 2.8-9). Inspection Importance and RRWI are the risk due to accident sequences containing the i-th system. Fussell- Vesely Importance is similar except it is divided by the risk so may be interpreted as the fraction of the total risk that is in the sequences contains the Q-th system. The Risk Achievement Worth Ratio (RAWR) is the ratio of the risk with system 1 failed to the total risk and is necessarily greater than one. The Risk Achievement Worth Increment (RAWI) is the incremental risk increase if system 1 fails and the Risk Reduction Worth Ratio (RRWR) is the fraction by which the risk is reduced if system 1 were infallible. [Pg.64]

In this case, the operations within a sequence are further defined according to various criteria such as whether they involve reception or transition of information, storage of information, manual control responses, inspections, and decisions. However, some other dimensions of an operation may require particular emphasis such as whether information is transmitted electronically, by external communication etc. A type of vertical axis can still be used to represent sequential order and if required this can incorporate the same timing information as temporal OSDs. [Pg.175]

In Section 21.4 tlie effects of the release of toxic vapors were considered in connection witli an accident sequence initiated by the failure of a plant programmable automatic controller. In tliis study, event tree analysis and fault tree analysis led to identification of tlie glycol cooling system circulation pumps as components meriting high priority for inspection. [Pg.634]

Inspection of models show that the interaction between the non-bonded atoms is different in an isotactic and a syndiotactic sequence. A somewhat naive calculation based on van der Waals repulsions between the nonbonded atoms, suggests that for nonpolar vinyl monomers the syndiotactic sequence may be favored by a few tenths of a kcal/mole, and this difference might increase to... [Pg.164]

Inspecting and maintaining the interlock system is a vital function. It is required to ensure general safety and to avoid risks of boiler explosion. Interlocks provide for the safe sequence of boiler startup and shutdown procedures. [Pg.121]

Preparing a boiler for inspection requires the operator to first follow a sequence of specific boiler shutdown procedures, including cooling the boiler slowly to prevent undue stress to the metal and refractory. The primary purpose of the inspection process is to ensure continued boiler safety, and therefore a thorough inspection of all appurtenances is mandatory. [Pg.124]

Ion exchange plant should be put into regeneration and inspected for correct sequence timing, backwash rate, regenerant draw, rinse times, and slippage from the service valve. [Pg.615]

At this time, more then thirty channel DNAs have been cloned and characterized from various sources, predominantly from Drosophila melanogaster, mouse, rat and human cDNA/genomic libraries [6-31]. Inspection of the derived primary K channel protein sequences indicates that voltage-gated channels belong to a... [Pg.297]

When one inspects the multiple channel protein sequences that have been derived, one readily recognizes that they have related primary sequences. This suggests that they have similar three-dimensional structures. The primary sequences can be subdivided into an amino-terminal, a core and a carboxy-terminal domain (see Fig. 5). Each domain seems to contribute separately to the structure and function of a given channel [49]. Following this hypothesis, it has been possible to carry out domain swapping experiments between Sh and RCK proteins [49] as well as between... [Pg.308]

The program must require the vendors to measure a number of reference samples and/or duplicates submitted in a planned sequence. It should require prompt measurement and reporting of these data and should maintain the results in a control chart format. Prompt feedback and follow-up of any apparent data discrepancies and reconciliation of the results with control charts maintained by the vendors are required to minimize the length of uncertain performance. The quality assurance plan should include random sampling of the vendors data for their validity and conformance with quality assurance requirements. If quality assurance is properly practiced at all levels, an inspection of 5 percent of the total data output should be adequate. [Pg.106]
