Determination of the Optimum formula for Composite Motor Gasoline Octane Number Blending Enhancer
Journal of Engineering, 2019 To decrease the dependency of producing high octane number gasoline on the catalytic processes in petroleum refineries and to increase the gasoline pool, the effect of adding a suggested formula of composite blending octane number enhancer to motor ...

Composite functional metasurfaces for multispectral achromatic optics [PDF]
Nature Communications, 2016 Nanostructured metasurfaces offer unique capabilities for subwavelength control of optical waves. Based on this potential, a large number of metasurfaces have been proposed recently as alternatives to standard optical elements.

Approximation numbers of weighted composition operators [PDF]
Journal of Functional Analysis, 2018 We study the approximation numbers of weighted composition operators $f\mapsto w\cdot(f\circ )$ on the Hardy space $H^2$ on the unit disc. For general classes of such operators, upper and lower bounds on their approximation numbers are derived. For the special class of weighted lens map composition operators with specific weights, we show how much the

Approximation and entropy numbers of composition operators [PDF]
Concrete Operators, 2020 Abstract We give a survey on approximation numbers of composition operators on the Hardy space, on the disk and on the polydisk, and add corresponding new results on their entropy numbers, revealing how they are different.

Narayana numbers and Schur–Szegő composition [PDF]
Journal of Approximation Theory, 2009 AbstractIn the present paper we find a new interpretation of Narayana polynomials Nn(x) which are the generating polynomials for the Narayana numbers Nn,k=1nCnk−1Cnk where Cji stands for the usual binomial coefficient, i.e. Cji=j!i!(j−i)!. They count Dyck paths of length n and with exactly k peaks, see e.g. [R.A. Sulanke, The Narayana distribution, in:

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Distribution of Composite Numbers and Determination of Prime Numbers
, 2021 Integer is either a composite number or a prime number. Therefore, detecting composite numbers is important for solving prime numbers. The study of prime numbers, apart from satisfying human curiosity, can be very important. In this article, the order of composite numbers has been detected. And explained with a simple method and a simple function. And,
