R-parameter: a local truncation error based adaptive framework for finite volume compressible flow solvers. Comput Fluids 2009;38(9):1799-822.N. Ganesh, Nikhil V. Shende, and N. Balakrishnan, R-Parameter: A Local Truncation Error Based Adaptive Framework for Finite Volume Compressible Flow ...
High-order methods inspired by the multi-step Adams methods are proposed for systems of fractional differential equations. The schemes are based on an expansion in a weighted L2 space. To obtain the schemes this expansion is terminated after P+1 terms. We study the local truncation error and ...
A transport-level error has occurred when receiving results from the server. (provider: Shared Memory Provider, error: 0 - The pipe has been ended.) A truncation occurred during evaluation of the expression Acces to the path is denied when trying to save a SSIS item Access CSV file from an...
In this situation, the standard fourth order compact scheme can be applied, with the possibility of modifying the finite difference formula A fourth order compact scheme Let us assume that the 2D square domain in question is discretized with unequal meshsize in different coordinate directions. In ...

By the fractional Poincaré type inequality (see, e.g., Proposition 5.1, Formula (6.3) in [20]) and the assumption in (2.1) for K we get⨍Br|v−(v)Br|pdx≤crsp−n∫Br∫BrK(x,y)|v(x)−v(y)|pdxdy with a constant c≡c(n,p,s,λ,Λ). Now observe that v is a tr...
After obtaining the gain region, the relevant idea of error correction method is used, as shown in (7) In the formula, BLgain is the average gray value of the gray image gain area; K is the gain coefficient. Cor is the correction amount obtained by introducing the error correction metho...
which allows for capturing both global and local structural information. The inclusion of luminance, contrast, and structure components in the formula makes SSI a useful metric for evaluating the perceptual quality of images, which is particularly important in applications like image compression, image ...
