The requirement given as Eq. (15) in ISO 16505 2015 is an expansion of the above equation to nominal resolution requirement given for the required minimum field of view to the monitor defined size of Wmonitor/hor, where the first factor (Wmonitor/hor/Wmonitor/hor/min) IS the sizc Compensation factor to expand the evaluation window from Wmonitor/hor/min to Wj onitor/hor- Considering the dependency of the nominal value to the measured image size, the same Eq. (15) is denoted as shown by the following Eq. (3)... [Pg.110]

When evaluating a CMS of class VI, a large deviation to the assumption given in Eq. (4) may occur especially if the monitor defined size is expanded to an extreme wide angle. CMS exhibiting large peripheral distortion is likely be affected. It is therefore advised to determine the requirement value in the smallest possible monitor defined size, preferably near or equal to the required minimum field of view. [Pg.111]

To visuahze the requirement, let us assume that the black and white parallel bar in Fig. 3 is an image of a chart filled with parallel bars of a spatial frequency representing resolution (MTF) minimum requirement with a modulation of exactly 10 %. The horizontal resolution if measured in the applicant declared monitor defined size of will be hd l Fl0miN(1 l)/hor0 monitor/hor) — [LW/PH]. [Pg.113]

The resolution (MTF) or sharpness is measured in the centre and in the four corner region of the image within the area defined as monitor defined size. Each... [Pg.124]

Finally, the concentrated localized AE events are represented on the monitor in the form of a histogram "number of localized AE events vs axial coordinate", which is automatically updated at user-defined time intervals. [Pg.69]

Figure 5 provides an example of AE monitoring data from 22.01.1997 to 03,03.1997, in terms of time history of the main plant parameters (fig.Sa), as well as of the AE RMS values (fig. 5b). Normally, very little or no events were recorded, with the exception of the above period, in which an AE activity, very much concentrated in time and space, could be observed a sharp step in cumulative AE events takes place in a short, well defined time interval. A smaller sharp step in EA events had been observed a few days earlier, in the same position. [Pg.78]

To operate the MPI or LPI equipment at stable and reprodncable inspection conditions modern units are equipped with a monitoring and control system called "Quality Assurance Package" (termed QAP). The QAP System is ba.sed on an industrial PC with a bus system and field sensors. It ensures that process parameters important for the reproducability of the MPI or LPI are controlled an held between defined limits by a central computer system. It can be adapted to any old system, as well as integrated into new systems. [Pg.628]

In order that the data acquisition system can obtain information about the spatial location and orientation of the probe, a four-channel incremental encoder interface board is installed. Three channels are used to define position in three-dimensional space, while the fourth monitors the skew of the probe (skew is defined as rotation about an axis normal to the probe face). Although six measurements are required to completely define the location and orientation, it is assumed that the probe remains in contact with the inspection surface. [Pg.768]

In figure A3.3.9 the early-time results of the interface fonnation are shown for = 0.48. The classical spinodal corresponds to 0.58. Interface motion can be simply monitored by defining the domain boundary as the location where i = 0. Surface tension smooths the domain boundaries as time increases. Large interconnected clusters begin to break apart into small circular droplets around t = 160. This is because the quadratic nonlinearity eventually outpaces the cubic one when off-criticality is large, as is the case here. [Pg.743]

As a increases, a critical value " i-.iiiis reached each time the th layer of target atoms moves out of the shadow cone allowing for large-angle backscattering (BS) or small-/i collisions as shown in figure Bl.23.3. If the BS intensity 1, is monitored as a fimction of a, steep rises [36] witli well defined maxima are observed when the... [Pg.1813]

Perturbation or relaxation techniques are applied to chemical reaction systems with a well-defined equilibrium. An instantaneous change of one or several state fiinctions causes the system to relax into its new equilibrium [29]. In gas-phase kmetics, the perturbations typically exploit the temperature (r-jump) and pressure (P-jump) dependence of chemical equilibria [6]. The relaxation kinetics are monitored by spectroscopic methods. [Pg.2118]

In order to compare the efficiency of the SISM with the standard LFV method, we compared computational performance for the same level of accuracy. To study the error accumulation and numerical stability we monitored the error in total energy, AE, defined as... [Pg.342]

Example Yon can monitor improper torsion angles to determine wh ich side of a substrate m olecn le faces the active site of a protein. Select three atoms on the substrate molecule and a fourth in the active site. These atom s define an improper torsion angle. Save th is selection as a named selection. Then observe a plot of this improper torsion angle (in the Molecular Dynam ics Results dialog... [Pg.87]

To find the end point we monitor some property of the titration reaction that has a well-defined value at the equivalence point. Eor example, the equivalence point for a titration of ITCl with NaOlT occurs at a plT of 7.0. We can find the end point. [Pg.275]

Although not commonly used, thermometric titrations have one distinct advantage over methods based on the direct or indirect monitoring of plT. As discussed earlier, visual indicators and potentiometric titration curves are limited by the magnitude of the relevant equilibrium constants. For example, the titration of boric acid, ITaBOa, for which is 5.8 X 10 °, yields a poorly defined equivalence point (Figure 9.15a). The enthalpy of neutralization for boric acid with NaOlT, however, is only 23% less than that for a strong acid (-42.7 kj/mol... [Pg.294]

The term aquifer is used to denote an extensive region of saturated material. There are many types of aquifers. The primary distinction between types involves the boundaries that define the aquifer. An unconfined aquifer, also known as a phraetic or water table aquifer, is assumed to have an upper boundary of saturated soil at a pressure of zero gauge, or atmospheric pressure. A confined aquifer has a low permeabiUty upper boundary that maintains the interstitial water within the aquifer at pressures greater than atmospheric. For both types of aquifers, the lower boundary is frequendy a low permeabihty soil or rock formation. Further distinctions exist. An artesian aquifer is a confined aquifer for which the interstitial water pressure is sufficient to allow the aquifer water entering the monitoring well to rise above the local ground surface. Figure 1 identifies the primary types of aquifers. [Pg.401]

Because of the large number of samples and repetitive nature of environmental analysis, automation is very important. Autosamplers are used for sample injection with gc and Ic systems, and data analysis is often handled automatically by user-defined macros in the data system. The high demand for the analysis of environmental samples has led to the estabUshment of contract laboratories which are supported purely by profits from the analysis. On-site monitoring of pollutants is also possible using small quadmpole ms systems fitted into mobile laboratories. [Pg.548]

Pubhc concerns about pesticides in the diet of infants and children resulted in an expert committee convened by the U.S. National Academy of Sciences which devoted four years to the review of all available data. A consensus report was issued in 1993 (80). A number of recommendations for further work to more precisely define what constitutes the diet of infants and children were made. No risk could be estimated. The residue data reviewed by the panel were mainly from monitoring studies conducted by the PDA using multiresidue methods to analyze fresh produce and market basket samples collected from various geographic areas (81,82). These and other rehable scientific studies have demonstrated that relatively few food samples contain detectable residues. Most residues are far below estabhshed tolerances which are set above the maximum residue found in treated raw agricultural... [Pg.150]
