This paper is devoted to the computation of transmission eigenvalues in inverse acoustic scattering theory. problem first reformulated as a two by boundary system integral equations. Next, utilizing Schur complement technique, we develop operator with regularization obtain reduced The Nystrom discretization then used an eigenvalue for matrix. We employ recursive method numerical matrix eigenval...

In this paper, an effective numerical method for the Dirichlet problem connected with Helmholtz equation is proposed. We choose a single-layer potential approach to obtain boundary integral density function, and then we deal weakly singular kernel of via value decomposition Nystrom method. The direct noisy data solved using Tikhonov regularization method, which used filter out errors in conditi...

A semi-spectral Chebyshev method for solving numerically singular integral equations is presented and applied in the quarkonium bound-state problem in momentum space. The integrals containing both, logarithmic and Cauchy singular kernels, can be evaluated without subtractions by dedicated automatic quadratures. By introducing a Chebyshev mesh and using the Nystrom algorithm the singular integra...

In this work, the existence and uniqueness solution of fractional nonlinear mixed integro-differential equation (FrNMIoDE) is guaranteed with a general discontinuous kernel based on position time-space L2Ω×C0,T, T<1. The FrNMIoDE conformed to Volterra-Hammerstein integral (V-HIE) second kind, after applying characteristics integral, in for Hammerstein term continuous time Volterra (VI) term....

Moral judgments are not produced by a unified “moral faculty.” Instead, they are influenced by a combination of automatic emotional responses and controlled cognitive processes with distinctive cognitive profiles (Cushman, Young, & Hauser, 2006; Greene, Morelli, Lowenberg, Nystrom, & Cohen, 2008; Moore, Clark, & Kane, 2008; Paxton, Ungar, & Greene, 2011) and neural substrates (Greene, Sommervil...

We introduce a fast algorithm for computing volume potentials that is, the convolution of a translation invariant, free-space Green’s function with a compactly supported source distribution defined on a uniform grid. The algorithm relies on regularizing the Fourier transform of the Green’s function by cutting off the interaction in physical space beyond the domain of interest. This permits the ...

a r t i c l e i n f o Managers construct organizational façades that mislead external stakeholders, organizational members, auditors, researchers, other managers, and even themselves (Nystrom & Starbuck, 1984). Very little empirical research has been conducted on how managers build these façades since Nystrom & Starbuck's first influential article. This paper reports on the creation of an organ...
