Design criteria reflection

The reflection coefficient and return loss are, in general, a function of the frequency. A typical design criterion requires that the reflection coefficient satisfies r = 5ii < —10 dB, for fi less than 10% of the power injected at the antenna terminals may be reflected, over the frequency band fL,fH -...

Both discovery and discrimination in screens hinge on the decision criterion that is used to determine if activity has or has not been detected. How sharply such a criterion is defined and how well it reflects the working of a screening system are two of the critical factors driving screen design. 

Paper walling is only one method among many available, but it cannot stand alone. The operation of an existing as well as a streamlined operation may be illustrated in many ways, inspired by formalized information and logistic architecture methods. The main objective of ensuring a lean and streamlined operation will have to be translated into system requirements and in turn a system design that enables the actual system to be built. A key success criterion is how well the outcome in the computer system design reflects a user-friendly and streamlined flow of operation and information in the paperless facility. 

A common metric to determine the optimal photoresponse is the photocurrent density under 1 sun illumination (1,000 W/m ). To be able to compare the photocurrent for different samples, two criteria should be fulfilled. The main one is that the measured data reflect the properties of the sample, as opposed to artifacts or limitations caused by the measurement setup. For example, mass transport limitations should be avoided by careful design of the electrochemical cell, and Ohmic losses and pH fluctuations can be avoided by choosing a suitable electrolyte. For a meaningful comparison of performance numbers reported by different laboratories one should also fulfill the second criterion, which is that the measurements must be...
