Discrete indicators

Two types of diffraction patterns are encountered in practice in the first, the reflections are discrete indicating that the internal structure of the particle is crystalline, in the second, there is a continuous distribution of intensity along discrete layer lines indicating that the particle is helical. In a particle containing helices arranged on a crystalline lattice the diffraction pattern will of course be of the first type. In the present description we limit consideration to cases where the natural breadth of reflections or layer lines from individual particles does not lead to significant overlap. 

Discrete indicators are tracked by looking at their success rate. For the appearance indicator in our example, we are interested in the number of passes, considering the total number of observations or survey responses. 

Discrete indicators, such as appearance, will typically have a target value of none or 0 we would always want our test to pass. For example, customers might be asked if the appearance of a product pleases them or not. They can answer yes (pass) or no (fail) on a questionnaire. 

Note that search is a serial sequential process, terminating upon successful detection of a discrete indication (such as a surface scratch) caU a target in visual search. Because of its sequentieil nature, it is a resource-hmited rather than data-fimited process (Wickens 1991). As such, the probability of detection increases with time spent searching in a manner dependent upon the search plan. 

Indication of safety valve leakage is provided by the Acoustic Leak Monitoring System (ALMS). The signal from the accelerometer sensor is monitored continuously, along with the RMS value of the signal computed. These signals are compared to a pre-established baseline value and alarmed in the main control room via the Nuplex 80+ Data Processing System (DPS) and Discrete Indication and Alarm System (DIAS) displays (See Section 7.7). 

Instrument and computer applications of these discrete devices include indicator lamps, numeric and alphanumeric displays, and LED backlighting of liquid crystal displays. Higher performance LEDs are often used for the backlighting application. Consumer electronics applications (audio equipment, home appliances, clocks, radios, toys, etc.) include discrete indicator lamps and numeric and alphanumeric displays. 

Processing System (DPS), and the Discrete Indication and Alarm System (DIAS). These display systems have been designed and configured (as described in CESSAR-DC Sections 7.7.1.4, 7.7.1.5, and 7.7.1.7) such that the loss of any one of them does not result in a total loss of necessary information. 

The Nuplex 80+ CRTs are driven by the Data Processing System (DPS) described in CESSAR-DC Section 7.7.1.7. The DPS is a computer-based system that provides plant data and status information to the operator, derived or processed from plant sensors including the Post Accident Monitoring Instrumentation sensors. The information is available on both a real-time and historical basis. SPDS and other information necessary for the handling of emergency plant conditions and assessment of their consequences is also provided by the DPS to the TSC and EOF when they are activated and manned, as described in CESSAR-DC Sections 13.3.3.1 and 13.3.3.2 respectively. Key parameter values processed by the DPS are also indicated directly via the Discrete Indication and Alarm System (CESSAR-DC Section 7.7.1.4) on discrete indicators located on the main control room and remote shutdown panels. 

ICC monitoring information is provided to the operator through the Discrete Indication and Alarm System (DIAS) Channel N and the Data Processing System (DPS) displays in the main control room. A complete description of the inadequate core cooling monitoring instrumentation is provided in CESSAR-DC, Sections 7.5.1.1.7 and 7.7.1.1.0. 

Od are just the names of the points of the continuum, the Poincar invariant Lagrange-(or Gauss-) coordinates. A system of N discrete mass points is described by an invariant time parameter t and N discrete indices z (t,i) = zJ (t), i = 1,...N. A string... 

The physical interpretation of what happens in forming a chemical bond has been the subject of much controversy (see, in particular, Ruedenberg (1962) what is beyond dispute, however, is that the only attractions (i.e. negative terms in the energy) are contained in The term matrix is in some ways unfortunate. It arises because p(x x ) is analogous to a matrix element in which the discrete indices r, s have been replaced by continuous variables x, x. ... 

It has been noted (footnote on p.l24) that p(xi xl) formally resembles a matrix element, in which Xi andxj play the part of (continuous) row and column indices in this sense it provides a particular representation of p. We now note that, on introducing any orthonormal set i/ r(JCi) > the array of coefficients appearing in (6.4.1) simply provides a true matrix representation of the operator p, in which Xj, x[ are replaced by the discrete indices r, s. This follows easily from the definition of the matrix elements of an operator since, using the orthonormality property,...
