The Darwinian Particle Swarm Optimization (DPSO) is an evolutionary algorithm that extends the Particle Swarm Optimization using natural selection to enhance the ability to escape from sub-optimal solutions. An extension of the DPSO to multi-robot applications has been recently proposed and denoted as Robotic Darwinian PSO (RDPSO), benefiting from the dynamical partitioning of the whole populat...

Varicella is a common viral infection that occasionally results in scar. Despite a number of measurements taken to combat this infection, they have all been either impractical or limited.The current study presents a 28-year-old woman diagnosed with varicella 10 years ago which caused her to have several depressed skin scars over the face. She was subjected to sequential treatment of punch eleva...

effects of formulation parameters on the fractional release profile of diclofenac sodium from matrices having the manufacturing formulation ingredients are studied. as a content of cetyl alcohol (rate controlling agent) in the matrix increases, the fractional release decreases. the fractional release increases either by increasing sucrose content outside the granule or by decreasing sucrose con...

In this paper‎, ‎a modern method is presented to solve a class of fractional optimal control problems (FOCPs) indirectly‎. ‎First‎, ‎the necessary optimality conditions for the FOCP are obtained in the form of two fractional differential equations (FDEs)‎. ‎Then‎, ‎the unknown functions are approximated by the hybrid functions‎, ‎including Bernoulli polynomials and Block-pulse functions based o...

A universal approach by Laplace transform to the variational iteration method for fractional derivatives with the nonsingular kernel is presented; in particular, the Caputo-Fabrizio fractional derivative and the Atangana-Baleanu fractional derivative with the non-singular kernel is considered. The analysis elaborated for both non-singular kernel derivatives is shown the necessity of considering...

We propose an adaptive reversible data hiding method with superior visual quality and capacity in which an adaptive generalized difference expansion (AGDE) method is applied to an integer-to-integer subband transform (I2I-ST). I2I-ST performs the reversible subband transform and the AGDE method is a state-of-the-art method of reversible data hiding. The results of experiments we performed objec...

This paper describes and compares techniques for registering an image with respect to a template image when one or both are partially occluded. These techniques can be used to build correlation-based image registration (alignment of similar images) and image search (finding a sub-image within a larger image) algorithms. Binary masks as developed by Stone and Shamoon [18], and extended by Stone ...

In the paper, a programmable phase-locked loop (PLL) based ISM band fractional-N frequency synthesizer, commonly used in wireless communication system, is presented. The third order error-feedback Delta-Sigma modulator and high linearity offset phase frequency detector (PFD)/ Charge Pump (CP) are adopted to reduce close-in phase noise due to ∆Σ quantization noise folding. Automatic calibration ...

Sub-wavelength traffic grooming in optical networks has gained significant importance in recent years due to the prevailing fractional wavelength traffic requirement of end-users. Dynamic routing schemes improve the performance of WDM grooming networks compared to static routing as they can adapt to changes in the network state. In this paper, the significance of dynamic routing of fractional w...
