it should be kept for a while, i.e. a few msec which corresponds to 1 million cycles when it comes to 1GHz clock. Therefore, the change of supply voltage must guarantee that it is enough to support the workload of next, let’s say 1 million cycles. The prediction of future workload is one of open res[r]

We must estimate the weather condition far before necessity while, with the use of electromagnetic waves, there is no need to an exact prediction of weather condition. Regarding these advantages, it seems that this method can find a suitable place among the other methods in anti-freezing application[r]
