Methods for Extension of Tunability Range in Synthetic Inductance Simulators

open access: yesElektronika ir Elektrotechnika, 2018
Presented work focuses on methods for the extended electronic control in the designs of inductance simulators based on single-loop feedback topology. Implementation is based on diamond transistors as voltage-to-current converters and two voltage-mode ...

Energy consistent discontinuous Galerkin methods for a quasi-incompressible diffuse two phase flow model [PDF]

open access: yes, 2013
We design consistent discontinuous Galerkin finite element schemes for the approximation of a quasi-incompressible two phase flow model of Allen--Cahn/Cahn--Hilliard/Navier--Stokes--Korteweg type which allows for phase transitions.

Synthesis and Optimization of Fractional-Order Elements Using a Genetic Algorithm

open access: yesIEEE Access, 2019
This study proposes a new approach for the optimization of phase and magnitude responses of fractional-order capacitive and inductive elements based on the mixed integer-order genetic algorithm (GA), over a bandwidth of four-decade, and operating up to 1

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Vehicle-bridge dynamic interaction using finite element modelling [PDF]

open access: yes, 2010
First investigations on the dynamic response of bridges due to moving loads were motivated by the collapse of the Chester railway bridge in the UK in the middle of the 19th century.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Cephamycin; A Novel Corrosion Inhibitor for Mild Steel Corrosion in HCl Acid Solution

open access: yesInternational Journal of Electrochemical Science, 2013
The corrosion inhibition properties of cephamycin (CFC) for mild steel corrosion in HCl solution were analysed by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization methods.

Salt Solution Concentration Effects on the Electrochemical Impedance Spectroscopy of Poly(3,4‐ethylenedioxythiophene) (PEDOT)

open access: yesChemElectroChem, 2022
Poly(3,4‐ethylenedioxythiophene) (PEDOT) has become a widely used modifier for biomedical electrodes because of its ability to significantly decrease the impedance at low frequencies (below 1 kHz).

Modeling and simulation of Constant Phase Element for battery Electrochemical Impedance Spectroscopy [PDF]

open access: yes2019 IEEE 5th International forum on Research and Technology for Society and Industry (RTSI), 2019
This paper presents a set of time-domain electrical equivalent circuit models for battery voltage prediction under arbitrary current profiles. The circuit model is composed by passive electrical components like resistance, inductance and capacitance.
