Beyond the poor man's implementation of unconditionally stable algorithms to solve the time-dependent Maxwell Equations [PDF]
, 2001 For the recently introduced algorithms to solve the time-dependent Maxwell equations (see Phys.Rev.E Vol.64 p.066705 (2001)), we construct a variable grid implementation and an improved spatial discretization implementation that preserve the property of ...

Unconditionally stable algorithms for nonlinear heat conduction [PDF]
Computer Methods in Applied Mechanics and Engineering, 1977 Abstract It is shown that many commonly used one-step algorithms which are unconditionally stable for linear transient heat conduction problems become conditionally stable in the nonlinear regime. Alternative algorithms are proposed which for linear problems are identical to those commonly used, whereas for nonlinear problems the unconditional ...

An Operator-Difference Method for Telegraph Equations Arising in Transmission Lines
Discrete Dynamics in Nature and Society, 2011 A second-order linear hyperbolic equation with time-derivative term subject to appropriate initial and Dirichlet boundary conditions is considered. Second-order unconditionally absolutely stable difference scheme in (Ashyralyev et al.

Applied Sciences, 2021 Although many families of integration methods have been successfully developed with desired numerical properties, such as second order accuracy, unconditional stability and numerical dissipation, they are generally implicit methods.

Unconditionally secure quantum key-distribution with relatively strong signal pulse [PDF]
, 2007 We propose an unconditionally secure quantum key distribution (QKD) protocol, which uses a relatively strong signal pulse. While our protocol shares similar security bases as the Bennett 1992 protocol with a strong reference pulse (B92), our scheme uses ...

Unconditionally Stable Shock Filters for Image and Geometry Processing [PDF]
Computer Graphics Forum, 2015 AbstractThis work revisits the Shock Filters of Osher and Rudin [OR90] and shows how the proposed filtering process can be interpreted as the advection of image values along flow‐lines. Using this interpretation, we obtain an efficient implementation that only requires tracing flow‐lines and re‐sampling the image.

A Truly Second-Order and Unconditionally Stable Thermal Lattice Boltzmann Method
Applied Sciences, 2017 An unconditionally stable thermal lattice Boltzmann method (USTLBM) is proposed in this paper for simulating incompressible thermal flows. In USTLBM, solutions to the macroscopic governing equations that are recovered from lattice Boltzmann equation (LBE)
