Electrical Impedance Response of Gamma Irradiated Gelatin based Solid Polymer Electrolytes Analyzed Using a Generalized Calculus Formalism
TL;DR: In this paper, the electrical impedance response of Gelatin based solid polymer electrolyte to gamma irradiation is investigated by impedance spectroscopy using an analysis based on Poisson-Nernstst-Plank model, incorporating fractional time derivatives.
Journal ArticleDOI
Unstable crack propagation in LAPONITE® gels: selection of a sinusoidal mode in an electric field
Somasri Hazra,Sudeshna Sircar,Tajkera Khatun,Moutushi Dutta Choudhury,Abhra Giri,Sanat Karmakar,Tapati Dutta,Shantanu Das,Sujata Tarafdar +8 more
TL;DR: In this paper, the authors observed wavy cracks and naturally patterned fracture surfaces in drying LAPONITE® paste and provided an insight into the mechanism of wavelength selection under an electric field of sufficient strength.
Proceedings ArticleDOI
Genetic Algorithm Based Improved Sub-Optimal Model Reduction in Nyquist Plane for Optimal Tuning Rule Extraction of PID and PIlambdaDi Controllers via Genetic Programming
TL;DR: From the Pareto optimal front which is a trade-off between the complexity of the formulae and control performance, an efficient set of tuning rules has been generated for time domain optimal PID and PIeDi controllers.
Proceedings ArticleDOI
Investigation of fractional dynamics and design of ultracapacitor based very low frequency oscillators
TL;DR: In this article, the authors address possible application of ultracapacitors for the design of very low frequency (VLF) oscillators and propose an approach that allows design of oscillators for a set of low frequency specifications.
Journal ArticleDOI
Effect of random parameter switching on commensurate fractional order chaotic systems
TL;DR: In this paper, the effect of random parameter switching in a fractional order (FO) unified chaotic system was investigated. And the authors showed that a noise-like random variation in the key parameter along with a gradual decrease in the commensurate FO is capable of suppressing the chaotic fluctuations much earlier than that with the fixed parameter one.
