In this article, we propose an adaptive grid based on mesh equidistribution principle for two-parameter convection-diffusion boundary value problems with continuous and discontinuous data. A numerical algorithm based on an upwind finite difference operator and an appropriate adaptive grid is constructed. Truncation errors are derived for both continuous and discontinuous problems. Parameter uni...

Ideal integrating nephelometers integrate light scattered by particles over all directions. However, real nephelometers truncate light scattered in near-forward and near-backward directions below a certain truncation angle ~typically 7°!. This results in truncation errors, with the forward truncation error becoming important for large particles. Truncation errors are commonly calculated using M...

Consider the model φ(S(z|X)) = β(z)t ~ X, where φ is a known link function, S(·|X) is the survival function of a response Y given a covariate X, ~ X = (1,X,X2, . . . ,Xp) and β(z) = (β0(z), . . . , βp(z)) t is an unknown vector of time-dependent regression coefficients. The response is subject to left truncation and right censoring. Under this model, which reduces for special choices of φ to e....

This comparison paper scrutinizes image compression using Block Truncation Coding. Many algorithms were selected likely the original Block Truncation coding, Absolute Moment Block Truncation Coding, a comparison survey was executed. These above techniques are divided image into non overlapping blocks. They distinguish in the direction of choosing the quantization level in order to remove redund...

Hamiltonian truncation is a non-perturbative numerical method for calculating observables of quantum field theory. The starting point this to truncate the interacting finite-dimensional space states spanned by eigenvectors free $H_0$ with eigenvalues below some energy cutoff $E_\text{max}$. In work, we show how treat systematically using effective theory methodology. We define integrating out a...
