On Convolved Generalized Fibonacci and Lucas Polynomials [PDF]

open access: yes, 2013
We define the convolved h(x)-Fibonacci polynomials as an extension of the classical convolved Fibonacci numbers. Then we give some combinatorial formulas involving the h(x)-Fibonacci and h(x)-Lucas polynomials.

An adaptive block‐wise prediction error‐based (AdaBPE) reversible data hiding in encrypted images for medical image transmission

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract Life expectancy has improved with new‐age technologies and advancements in the healthcare sector. Though artificial intelligence (AI) and the Internet of Things (IoT) are revolutionising smart healthcare systems, security of the healthcare data is always a concern.

Some properties and extended Binet’s formula for the class of bifurcating Fibonacci sequence

open access: yesRatio Mathematica
One of the generalizations of Fibonacci sequence is a -Fibonacci sequence, which is further generalized in several other ways, some by conserving the initial conditions and others by conserving the related recurrence relation.

On Quaternion-Gaussian Fibonacci Numbers and Their Properties

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021
We study properties of Gaussian Fibonacci numbers. We start with some basic identities. Thereafter, we focus on properties of the quaternions that accept gaussian Fibonacci numbers as coefficients.

Fibonacci numbers and words

open access: yesDiscrete Mathematics, 1997
AbstractLet Φ be the golden ratio (√5 + 1)/2, fn the nth Fibonacci finite word and f the Fibonacci infinite word. Let r be a rational number greater than (2 + Φ)/2 and u a nondashempty word. If ur is a factor of f, then there exists n ⩾ 1 such that u is a conjugate of fn and, moreover, each occurrence of ur is contained in a maximal one of (fn)s for ...

Neural Two‐Level Monte Carlo Real‐Time Rendering

open access: yesComputer Graphics Forum, EarlyView.
Abstract We introduce an efficient Two‐Level Monte Carlo (subset of Multi‐Level Monte Carlo, MLMC) estimator for real‐time rendering of scenes with global illumination. Using MLMC we split the shading integral into two parts: the radiance cache integral and the residual error integral that compensates for the bias of the first one.

Factorizations of the Fibonacci Infinite Word [PDF]

open access: yes, 2015
The aim of this note is to survey the factorizations of the Fibonacci infinite word that make use of the Fibonacci words and other related words, and to show that all these factorizations can be easily derived in sequence starting from elementary ...

From Genes to Shapes: Exploring Local Adaptation in Carpathian Ox‐Eye Daisies

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim Historical processes have shaped the Carpathian biogeography, yet ongoing evolutionary forces continue to drive population differentiation. We aimed to test whether local adaptation in the Carpathian subendemic Leucanthemum rotundifolium correlates with genetic, morphological and environmental factors, and to assess how these patterns ...

On Chebyshev Polynomials, Fibonacci Polynomials, and Their Derivatives

open access: yesJournal of Applied Mathematics, 2014
We study the relationship of the Chebyshev polynomials, Fibonacci polynomials, and their rth derivatives. We get the formulas for the rth derivatives of Chebyshev polynomials being represented by Chebyshev polynomials and Fibonacci polynomials.
