Deviating from the deterministic convention, this paper offers a stochastic-based approach to efficiently compute discrete Fourier transform (DFT) with reconfigurable digital fabric. This is made possible by leveraging a well-known probabilistic principle and exploiting the convolution theorem. The resulting hardware implementation demonstrates significant advantages in both hardware usage and energy...
This Electromagnetic Core Imperfection Detection (ELCID) has been widely used on generators and large motors in detecting inter-laminar insulation failure in stator cores. Comparing to traditional detecting method, the requirements of ELCID are much more easier to obtain, so it is necessary to analyze the results of ELCID in engineering application. On the one hand, the validity of ELCID in detecting...
In this paper, the traditional power minimization problem under some QoS constraints in a SISO cellular network is considered. However, the research is distinguished by two points. (1) The association relationship between base stations (BS) and users is no longer known and fixed. (2) When the QoS constraints are not satisfied, instead of simply claiming the problem is infeasible, the network tries...
For achieving the compensation method which is used for balancing the three-phase unbalanced load by TCR, unbalance factor, phase angle difference of positive and negative sequence component of three-phase voltage should be detected. Accuracy and rapidity of detection is the key factors which affects three-phase unbalance compensation effect. This paper proposes a calculating method of unbalance factor,...
This paper presents an adaptive image enhancement algorithm based on the vector closed operations, aiming at distinguishing features from impulse noise and salt & pepper noise, and solving the problem of the inconvenience in interactively modifying the parameter to adjust the contrast. According to the characteristic that grey level values arising from noise are normally weakly correlated and...
