ALGEBRAIC NONLINEARITY IN VOLTERRA-HAMMERSTEIN EQUATIONS [PDF]
Here a posteriori error estimate for the numerical solution of nonlinear Voltena- Hammerstein equations is given. We present an error upper bound for nonlinear Voltena-Hammastein integral equations, in which the form of nonlinearity is algebraic and ...

We consider a time-fractional diffusion equation for an inverse problem to determine an unknown source term, whereby the input data is obtained at a certain time. In general, the inverse problems are ill-posed in the sense of Hadamard. Therefore, in this

cgMSI: pathogen detection within species from nanopore metagenomic sequencing data
Background Metagenomic sequencing is an unbiased approach that can potentially detect all the known and unidentified strains in pathogen detection. Recently, nanopore sequencing has been emerging as a highly potential tool for rapid pathogen detection ...

A Posteriori Error Estimates for Axisymmetric and Nonlinear Problems
Suppose \(x_1\), \(x_2\), \(x_3\) denote the cylidrical coordinates in \(\mathbb{R}^3\). The authors first study the axisymmetric solution of \[ -\sum^3_{i=1} {\partial\over\partial x_i} \Biggl(A_i{\partial U\over\partial x_i}\Biggr)= F, \] in a rotation body with mixed Dirichlet and Neumann boundary conditions in order to establish a posteriori ...

This paper presents a study on the influence of the extrinsic information scaling coefficient value (eic) on the bit and frame error rate (BER/FER), for single and double binary turbo codes (S/DBTC) decoded with maximum a posteriori (MAP) and maximum ...

Nodal auxiliary a posteriori error estimates
We introduce and explain key relations between a posteriori error estimates and subspace correction methods viewed as preconditioners for problems in infinite dimensional Hilbert spaces. We set the stage using the Finite Element Exterior Calculus and Nodal Auxiliary Space Preconditioning.

Singular Cauchy Problem for a Nonlinear Fractional Differential Equation
The paper studies a nonlinear equation including both fractional and ordinary derivatives. The singular Cauchy problem is considered. The theorem of the existence of uniqueness of a solution in the neighborhood of a fixed singular point of algebraic type

divand-1.0: n-dimensional variational data analysis for ocean observations [PDF]
A tool for multidimensional variational analysis (divand) is presented. It allows the interpolation and analysis of observations on curvilinear orthogonal grids in an arbitrary high dimensional space by minimizing a cost function.
