Fractional-order inverting and non-inverting filters based on CFOA

This paper introduces a study to generalize the design of a continuous time filters into the fractional order domain. The study involves inverting and non-inverting filters based on CFOA where three responses are extracted which are high-pass, band-pass and low-pass responses. The proposed study introduces the generalized formulas for the transfer function of each response with different

Fractional-order synchronization of two neurons using Fitzhugh-Nagumo neuron model

This paper studies the synchronization of two coupled neurons using Fitzhugh-Nagumo model in the fractional-order domain. In general, studying systems in the fractional-order domain provides a wider scope view of their behavior. When the neuron is generalized into the fractional-order domain, the normal behaviors displayed in the integer case change. Furthermore, two neurons display various

Comparative study of fractional filters for Alzheimer disease detection on MRI images

This paper presents a comparative study of four fractional order filters used for edge detection. The noise performance of these filters is analyzed upon the addition of random Gaussian noise, as well as the addition of salt and pepper noise. The peak signal to noise ratio (PSNR) of the detected images is numerically compared. The mean square error (MSE) of the detected images as well as the

Novel permutation measures for image encryption algorithms

This paper proposes two measures for the evaluation of permutation techniques used in image encryption. First, a general mathematical framework for describing the permutation phase used in image encryption is presented. Using this framework, six different permutation techniques, based on chaotic and non-chaotic generators, are described. The two new measures are, then, introduced to evaluate the

Parameterized test patterns methodology for layout design rule checking verification

Design rules verification is an essential stage in the Process Design Kit (PDK) release for any fab. Since achieving high yield is the target of any fab, the design rules should ensure this. Design rules violations happening after fabrication lead to disastrous results on the mask sets as well as increased cost and delayed schedules. Here comes the importance of verifying these design rules and
