... original data point (boolean algebra) (see Ta ble 1 ). 5. CONCLUSION As a result we can draw the conclusion that the transforma- tion of an IEC 61131- based control system to an IEC 61499- based ... represent an average value calculator for one data point, but the left is IEC 61131 based, and the other, at the right side, is IEC 61499 based. Both of them have the same dat...

... order to acquire information about the whole matrix G at each AP, a feedback channel is usually needed to transmit the channel estimations from MTs to APs. With this information, each AP can solve ... comparing the average total network rate instead of the instantaneous total network rate. We de no te by u(M, N) the average total network rate for a M transmitters and N receivers...

... square of the detector area. This is because the numerator is always proportional to the square of the detector area and the shot noise variance is always proportional to the detector area. Hence, ... of them into a certain shape. For example, configuration B and C have the same spatial distributions as configuration A except that they have different arrangement of azimuth angles. As s...
