Combined Method Of Sight Reduction [PDF]

open access: yesTransNav, 2021
As ships and maritime transport have evolved, knowledge of navigation methods has also evolved, reaching today modern means that require less of the skills and time of navigators to determine the position of the ship on sees and oceans. However, the IMO

Analysis of the stress-strain state of a radially inhomogeneous transversely isotropic sphere with a fixed side surface

open access: yesAdvanced Engineering Research, 2022
Introduction. The paper considers an axisymmetric problem of elasticity theory for a radially inhomogeneous transversally isotopic nonclosed sphere containing none of the 0 and 𝜋 poles.

Separable reduction theorems by the method of elementary submodels [PDF]

open access: yes, 2011
We introduce an interesting method of proving separable reduction theorems - the method of elementary submodels. We are studying whether it is true that a set (function) has given property if and only if it has this property with respect to a special ...

Resonant semilinear Robin problems with a general potential

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
We consider a semilinear Robin problem driven by the Laplacian plus an indefinite and unbounded potential. The reaction term is a Carath\'eodory function which is resonant with respect to any nonprincipal eigenvalue both at $\pm \infty$ and 0.

Mulatu Numbers Which Are Concatenation of Two Fibonacci Numbers

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2023
Let (M_k) be the sequence of Mulatu numbers defined by M_0=4, M_1=1, M_k=M_(k-1)+M_(k-2) and (F_k) be the Fibonacci sequence given by the recurrence F_k=F_(k-1)+F_(k-2) with the initial conditions F_0=0, F_1=1 for k≥2.

A general reduction method for one-loop N-point integrals [PDF]

open access: yes, 2000
In order to calculate cross sections with a large number of particles/jets in the final state at next-to-leading order, one has to reduce the occurring scalar and tensor one-loop integrals to a small set of known integrals.

Curious Generalized Fibonacci Numbers

open access: yesMathematics, 2021
A generalization of the well-known Fibonacci sequence is the k−Fibonacci sequence whose first k terms are 0,…,0,1 and each term afterwards is the sum of the preceding k terms. In this paper, we find all k-Fibonacci numbers that are curious numbers (i.e.,

New symmetry reduction method for (1+1)-dimensional differential-difference equations

open access: yesFrontiers in Physics, 2023
We propose a new symmetry reduction method for (1+1)-dimensional differential-difference equations (DDEs), namely, the λ-symmetry reduction method of solving ordinary differential equations is generalized to DDEs.
