Negative bias temperature instability (NBTI) has deleterious impact on threshold voltage and drive current of PMOS transistor. In this paper, a support vector machine (SVM)-based surrogate model (SM) for NBTI phenomenon is developed within the framework of the HSPICE MOSFET reliability analysis (MOSRA) model for gain and slew rate of a differential amplifier. Feasibility space identification and adaptive...
In this paper, a cognitive classification and parameter estimation technique for the UWB through-wall propagation channel is proposed. For an investigated channel, a closed-loop cognitive radio system is proposed and the membership degree of each hypothesis channel is obtained for the channel classification and parameter estimation. The system contains an adaptive wave design technique in the transmitter,...
We consider the problem of failure detection in networks with energy and communication constraints. Most of current implementations of unreliable failure detectors (FD) use mechanisms to notify process failures in fully connected networks with reliable communication links. This assumption is not applicable to lossy networks. Furthermore, such implementations do not consider resource limitations in...
The design of adaptive test paper composition algorithm based on the item response theory is proposed and the ultimate goal of adaptive test is to measure the candidates' potential accurately. According to the item response theory, candidates' testing behavior is the reflection of their potential language ability and a potential of a candidate can be estimated directly by his/her item response together...
