Abstract This study introduces a time dependent fuzzy multi-objective reliability redundancy allocation problem (TF-MORRAP) for the $n$-stage (level) series parallel system. System maximization and system cost minimization according to by optimizing redundant components counting at every stage of is main objective this study. optimization done satisfying entropy constraints with limited in whole The component are represented as triangular numbers (TFN) handle uncertainty input information...
This paper introduced a reversible data hiding method based on pixel value ordering with the prediction-error expansion technique and average of end pixels'.A host image is first segmented into non-overlapping sub-blocks three pixels ordered them as ascending order.For each subblock maximum minimum predicted by middle also values.Then using expansions, we can embed secret bits these two bit every sub-block.All be recovered restored cover completely from watermarked image.Experimental result...
This paper presents a novel reversible data hiding method based on pixel value blocking and prediction-error expansion.A cover image is divided into non-overlapping sub-blocks of two pixels.Watermark bits are embedded in phases.In Phase-I, for each sub-block, second predicted by the first depending within threshold limit secret bit pixel.Also just adjusting location map without effecting value.Then another compressed used to indicate overflow/underflow or outer limit.Again Phase-II,...
This paper presents a better reversible data hiding method depending on pixel value ordering and prediction-error expansion technique.A host image is first segmented into non-overlapping sub-blocks of adjacent three pixels ordered them as ascending order.For each sub-block, the maximum predicted by second value.Then minimum or using expansions, we can insert one two secret bits every sub-block also recover hidden restore cover fully from watermarked image.Experimental results this...
In this work, we propose a new detector function based on wavelet transform to discriminate between turbulent and non-turbulent regions in an intermittent velocity signal. The derivative-based function, which is commonly used intermittency calculation schemes, shows large fluctuations within parts of the signal requires averaging over certain ``smoothing period'' remove fake drop-outs, introducing subjectivity calculating intermittency. proposed here obtained by ``pre-multiplied energy''...
