Different Variants of Bernstein Kantorovich Operators and Their Applications in Sciences and Engineering Field by Sumit Kaur Bhatia, Parveen Bawa, Neha Bhardwaj

“…Using chaos theory complexity is also reduced as in approximation theory. Thus in order to reduce complexity and to have better understanding of images in sciences and engineering field, sampling Kantorovich operators of approximation theory are widely used in this regard for enhancement of images. …”

A High Order Theory for Linear Thermoelastic Shells: Comparison with Classical Theories by V. V. Zozulya

“…Then in the same way as in the 3D theories system of differential equations in terms of displacements and boundary conditions for Fourier coefficients has been obtained. First approximation theory is considered in more detail. The obtained equations for the first approximation theory are compared with the corresponding equations for Timoshenko's and Kirchhoff-Love's theories. …”

On Sequences of J. P. King-Type Operators by Tuncer Acar, Mirella Cappelletti Montano, Pedro Garrancho, Vita Leonessa

“…In this paper we try to take stock of the situation and highlight the state of the art, hoping that this will be a useful tool for all people who intend to extend King’s approach to some new contents within Approximation Theory. In particular, we recall the main results concerning certain King-type modifications of two well known sequences of positive linear operators, the Bernstein operators and the Szász-Mirakyan operators.…”
