This paper presents a novel method to estimate displacement of a moving object based on model calibration in a weak feedback laser diode self-mixing system. A hybrid genetic algorithm is employed to locate the global minimum for the cost function which is constructed as the discrepancy between theoretically calculated system output and the experimental data. In turn, displacement measurement is achieved...
Dynamic sensor nodes selection strategy refers to the optimization for achieving the tradeoff between energy consumption and effective coverage rate, enhancing energy efficiency, enlarging the effective coverage rate and prolonging the lifetime of wireless sensor networks (WSN). This paper proposes a dynamic sensor nodes selection strategy, so-called HN-GA, which uses the genetic algorithm (GA) to...
This article presents the audio watermarking using multiple image-based watermarks based on genetic algorithms (GA) in the discrete wavelet transforms is proposed. Rather than using one watermark into a whole length of audio, we select appropriate watermarks in order to embed it into selected parts. It is robust against watermarking attacks, which are commonly employed in literature. In addition,...
Multiple-objective problems are a challenge for evolutionary algorithms. The requirement to improve the quality of the solution and at the same time maintain good candidates which may have different and conflicting objectives is a difficult one. This work proposes to apply the concept of building blocks to improve evolutionary algorithms to tackle such problems. Building block identification algorithm...
