We study the probability of error optimization problem in collaborative spectrum sensing (CSS) with limited time resources in cognitive radio (CR) networks. The frame structures for sensing and data transmission, if the spectrum is identified as vacant, are both assumed fixed. This implies that the time resource dedicated for CSS is limited and shared(More)
We study a collaborative spectrum sensing (CSS) problem with limited time and energy resources in cognitive radio (CR) network. Time duration of sensing and data transmission, if the spectrum is identified as vacant, are both supposed to be fixed. This implies that the time resource dedicated for CSS is limited and shared between results reporting time(More)
Acceptance control charts are one of the effective tools for monitoring capable processes, where the fraction of produced non-conforming items is very low. Due to high capability of the process, in these charts, controlled changes in the process mean are allowed. Although acceptance control charts are widely used in practice, it is often designed without(More)
The present research has been conducted with the aim of assessment of the impact of corrective exercises on the change of power and balance of adolescent girls suffering from scoliosis. For this purpose 30 students among those referred to Corrective Exercise Center of Tehran Dist. 4 Education Board within the age range of 13-16 years were selected.(More)
We study the probability of error optimization problem in collaborative spectrum sensing (CSS) with limited time and energy resources in energy harvesting cognitive radio (CR) networks. The frame structures for sensing and data transmission, if the spectrum is identified as vacant, are both supposed to be fixed. This implies that the time resource dedicated(More)
