Defect units

Hq there are no significant differences, in number of defective units, between workers... 

The expectation numbers were computed as follows For the Poisson distribution, X = E(x) therefore, an estimate of X is the average number of defective units per worker, i.e., X = (l/52)(0 x3-l-lx7-l---1-9x1) = 3.23. Given this... 

To irionitor the health of i capacitor unit it is tidvisable to provide an ammeter in each phase. When it is fotmd. that there is an tmbalance not caused by oltage unbalance then further investigations may be conducted to replace the defective unit(s) before a majoi fault occurs. 

The Kang and Eyring model too, features a structural defect unit upon which the entire 3-D lattice is constructed. On the basis of structural analysis carried out on the lower oxides of Ce, Pr and Tb. the following underlying principles governing... 

EXAMPLE 27-2 If the incidence of defective units coming from a production line is 2% and a random sample of 10,000 units is drawn, what is the expected number of defective units in the sample, and what is the standard deviation ... 

Diffusion of solutions of Cr, Co and Mn ions through a PTFE membrane allows for separation of Cr from the remaining ions. Thermal stability of polymeric materials is a significant consideration in many poly(phosphazene) applications. The kinetics of the thermal degradation of PTFE are best fit with a model requiring a two step initiation for depolymerization. These steps involve formation of defect units, such as =P(0)NH- and =P(0)N(CH2CFj)-, which become active centers for depolymerization. Mixed...

Acceptable quality level (AQL) inspection acceptance criteria are applied to the inspections. Visible foreign particulate matter is considered a critical defect. Thus, AQL levels (the greatest percentage of defective units still acceptable for release) are 0.25-1.0% of the lot size. Consult the American National Standards Institute/American Society for Quality Z1.4 guideline for more detailed information on AQL sampling. The drawbacks of manual inspection are that it is prone to human error and is subjective. 

X. is the concentration of the chain molecules with j defect units. 

Tj is the number of distinguishable conformational isomers in a chain molecule with j defect units. 

L is the maximum number of defect units that a chain molecule can accommodate. 

Accordingly the qualitative behavior of the ideal system is very similar to that of the two-level system represented by Eqs. (2.4-2.8). If the chain molecule is divided into L nonoverlapping segments, each of which can be occupied by a single defect unit. 

This is identical to the fundamental Eq. (2.4) for the two-level system if the specific energies f and Up are expressed in terms of the mass of the segments that can accommodate a defect unit and not the mass of the whole clmin molecule. 

An ideal system of liiKar chain molecule is certainly only fictitious. In reality, the intermolecular foicra exert an important influence on tte defect concentration and energetics. Since chain molecules with j and k defect units may assume entirely different conformations (cf Fig. 2.3), the pair concentrations x would haw to be split up into a sum, viz.
