in this paper we establish several polynomials similar to bernstein's polynomials and several refinements of  hermite-hadamard inequality for convex functions.

A robust technique is presented for parametric identification of linear time-invariant systems in the time domain. Based on a Sanathanan-Koerner iteration, the transfer function coefficients are calculated iteratively by minimizing a weighted linear cost function. The time-domain equivalent of the Muntz-Laguerre basis is used to improve the numerical conditioning of the associated system equati...

The output of simulations (e.g., global circulation models) can run into terabytes. The computational cost as well as the cost of storing and retrieving model data can be quite high. Recently there have been some e orts to develop on-line visualization capabilities that can be used, for example, to monitor whether the model is behaving properly. There are however, many other uses for on-line da...

Az alábbiakban két, eddig ismeretlen, 16. század eleji nyomtatványt mutatunk be, melyek 2021 tavaszán kerültek elő a szombathelyi Smidt Múzeum1 muzeális könyveinek feldolgozása során. Noha Erzsébet, múzeum korábbi igazgatója tollából több tanulmány is született az itt található nyomtatványok néhány kiemelkedő darabjáról, száz kötetes gyűjtemény szisztematikus, részletes csak napjainkban vette k...

A recent study has shown that the minimum separable angle of visual acuity of Octopus pallidus and O. australis lies between 4-4' and 9-7' when vertical and horizontal gratings are used as test objects (Muntz & Gwyther, 1988). In view of other observations the horizontal rectangular shape of octopus pupils, the pronounced astigmatism of the lens of Eledone cirrhosa (Sroczynski & Muntz, 1985), t...

In the paper, the authors view some ordinary differential equations and their solutions from the angle of (the generalized) derivative polynomials and simplify some known identities for the Bernoulli numbers and polynomials, the Frobenius-Euler polynomials, the Euler numbers and polynomials, in terms of the Stirling numbers of the first and second kinds.

Formulae expressing explicitly the coefficients of an expansion of double Jacobi polynomials which has been partially differentiated an arbitrary number of times with respect to its variables in terms of the coefficients of the original expansion are stated and proved. Extension to expansion of triple Jacobi polynomials is given. The results for the special cases of double and triple ultraspher...
