An explicit unconditionally stable scheme: application to diffusive Covid-19 epidemic model [PDF]

open access: yesAdvances in Difference Equations, 2021
An explicit unconditionally stable scheme is proposed for solving time-dependent partial differential equations. The application of the proposed scheme is given to solve the COVID-19 epidemic model.

Nanoscale radiofrequency impedance sensors with unconditionally stable tuning. [PDF]

open access: yesJ Appl Phys, 2009
Impedance sensors perform an important role in a number of biosensing applications, including particle counting, sizing, and velocimetry. Detection of nanoparticles, or changes in, e.g., the interfacial Debye–Hückel layer, can also be performed using nanoscale impedance sensors.

An Unconditionally Stable, Positivity-Preserving Splitting Scheme for Nonlinear Black-Scholes Equation with Transaction Costs [PDF]

open access: yesThe Scientific World Journal, 2014
This paper deals with the numerical analysis of nonlinear Black-Scholes equation with transaction costs. An unconditionally stable and monotone splitting method, ensuring positive numerical solution and avoiding unstable oscillations, is proposed.

Controlling the accuracy of unconditionally stable algorithms in Cahn-Hilliard Equation [PDF]

open access: yesPhysical Review E, 2006
Given an unconditionally stable algorithm for solving the Cahn-Hilliard equation, we present a general calculation for an analytic time step $\d \tau$ in terms of an algorithmic time step $\dt$.

Analyzing the dynamic patterns of COVID-19 through nonstandard finite difference scheme [PDF]

open access: yesScientific Reports
This paper presents a novel approach to analyzing the dynamics of COVID-19 using nonstandard finite difference (NSFD) schemes. Our model incorporates both asymptomatic and symptomatic infected individuals, allowing for a more comprehensive understanding ...

Semi-explicit Unconditionally Stable Time Integration method based on Generalized-α technique [PDF]

open access: yesمهندسی عمران شریف, 2022
In structural dynamic analysis, various time integration techniques have been proposed. Generally, these algorithms discretize the time domain into a finite number of intervals and approximate the displacements, velocities, and accelerations via ...

An unconditionally stable Voltage Regulator [PDF]

open access: yes2010 IEEE Asia Pacific Conference on Circuits and Systems, 2010
This paper describes a CMOS implementation of a Linear Voltage Regulator (LVR) used to power implanted systems. The topology is based on a classical structure of a Low Dropout Regulator (LDO) and receives his activation energy from a RF link characterizing a passive RFID tag. The LVR was designed to achieve important features like low power consumption,

Numerical Stability of Brusselator System [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2011
The numerical stability analysis of Brusselator system has been done in one and two dimensional space. For one dimension we studied the numerical stability for explicit and implicit (Crank- Nicolson) methods and we found that explicit method for solving ...

Flume Tests to Investigate the Initiation Mechanism of Loess Mudflows on the Chinese Loess Plateau

open access: yesFrontiers in Earth Science, 2021
Loess has a strong water sensitivity, so loess landslides often transform into loess mudflows when water is added on the Chinese Loess Plateau, which results in high casualties and property loss of the Chinese government. In this study, a series of flume
