Abstract Kinetic inductance travelling wave parametric amplifiers (KI-TWPAs) have been simulated using Keysight’s Advanced Design System. A lumped element representation of a superconducting transmission line has developed nonlinear inductor elements to represent the current dependency intrinsic kinetic inductance. This provides fast, simple and easily modifiable method for analysing processes ...

the modified surface of typha latifolia l. root (mstl), as an alternative economical adsorbent, wasused for the removal of ni (ii) and cd(ii) ions from aqueous solutions. the effect of initial ph, initialconcentration of metal ion, and contact time was investigated in a batch system at room temperature.the kinetics data could be fitted well by pseudo-second-order model with correlation coeffici...

The Exergetic Port-Hamiltonian Systems modeling language combines a graphical syntax inspired by bond graphs with port-Hamiltonian semantics akin to the GENERIC formalism. enables modular and hierarchical specification of composition pattern lumped distributed-parameter models. reflects first second law thermodynamics as structural properties. Interconnected hierarchically defined models multip...

the kinetic of photo oxidative decolorization of c.i. acid yellow 23 (ay23) was investigated in uv/ process. the semi-logarithmic of the concentrations of ay23 versus irradiation time were linear, suggesting pseudo-first order reaction. a simple kinetic model is proposed which confirms pseudo- first order reaction. the results indicate that the apparent reaction rate constant is a function of l...

in many flood control projects, watershed management and water resources development, calculation of the river flow discharge is of the paramount importance which requires a comprehensive hydrological modeling of the region of interest. in this respect, lack of the existence of hydrometric and meteorology measuring stations in most of watersheds, has caused numerous problems in development and ...

Mathematical modeling in the biofiltration of volatile organic compounds is a valuable tool for performance prediction and in scaling up. Majority of the published models include parameters obtained from fitting experimental data, thus masking their real influence as they are lumped generally. The present work aims to evaluate experimentally some of the most relevant parameters including kineti...
