In this study, the problem of energy-efficient power allocation (EEPA) for secrecy wireless information and power transfer in a massive multiple-input multiple-output relay aided secure communication system is well addressed. The relay forwards the signal sent from a source to a legitimate destination with the harvested energy based on a decode-and-forward relaying protocol, while a passive eavesdropper...
DC-DC boost converter in PWM switch mode is attractive for high power white LED constant current driver. The occurrence of uncertainty and coil magnetic saturation in DC-DC power converters makes their analysis and control difficult. A fuzzy logic controller (FLC) is then utilized to ensure current regulation over a wide range of parameters, which is perceived as an optimization problem. A robust...
For the speed control of film winding system, the pseudo-derivative feedback (PDF) controller is first selected. Controller parameters tuning then becomes a nonlinear constrained optimization problem with nonlinearity and load variations of film winding system. To avoid the selection of penalty parameters in constraint handling, NSGA-II is utilized by converting the nonlinear constrained optimization...
Kernel approach has been employed to solve classification problem with complex distribution by mapping the input space to higher dimensional feature space. However, one of the crucial factors in the kernel approach is the choosing of kernel parameters which highly affect the performance and stability of the kernel-based learning methods. In view of this limitation, this paper adopts the eigenvalue...
This paper has proposed and implemented a new optimized and adaptive error-resilient coding based on statistical parity pair embedding (SPPE). The SPPE can locate errors in the compressed I-frame bit stream and this system design can be applied to the MPEG2 wireless video applications. The SPPE is based on the information hiding technique. This SPPE algorithm is proven to have better performance than...
