semi‐implicit Euler methodspectral collocation methodstochastic partial differential equationIn this paper we investigate the numerical solution of stochastic partial differential equations (SPDEs) for a wider class of stochastic equations. We focus on non-diagonal colored noise instead of the usual space...
The thermal conductivity of the samples was measured with the modulated hot-wire sensor (HW), which is based on a hot-wire thermal probe with alternating current excitation and 3ωlock-in detection [29]. In the 3ωHW method, the hot wire on the probe is immersed in the fluid sample. ...
The implicit Euler method is shown to have excellent stability and rate of convergence. The relationship between the implicit Euler method and the NR method is elucidated, and it is shown that in the limit of infinite step-size, the implicit Euler method reduces to the NR method.doi:10.1080/...

A(k-1) and A(k) are the solutions for A at times t(k-1) and t(k). Thus the difference A(k) - A(k-1) is an indicator on how much the solution changes with time (so something like A'(t(k))*dt), but not an error in the Eul...
