A Modified Steffensen Iterative Method with Fourth-order Convergence

open access: yesJournal of Harbin University of Science and Technology, 2017
A new fourth-order convergent iterative method formed by Newton’s method and Steffensen method is presented to solve nonlinear equations in this paper. The new iteration formula uses derivative of quadratic interpolation as substitute for derivative of

Analogy of Weber's Electrodynamics Formula for Gravitation may Explain Dark Matter, Dark Energy, Hubble’s Law and Pioneer Anomaly

open access: yes, 2022
  Weber's electrodynamics formula for the force of interaction between movingcharged particles, which is a modification of Coulomb's law, may solve many of the paradoxes and puzzles in classical and relativistic electromagnetism. In this paper we propose

Abstract model power field electromagnetic type building. Part 1

open access: yesНаука. Инновации. Технологии, 2022
It is shown that the classical model of the magnetic field allows the violation of Newton's third law, eliminates interference elements coaxial conductors with currents, does not provide for the existence of moments of forces acting on the elements of ...

On the Expansion of the Remainder in the Newton-Cotes Formula [PDF]

open access: yesTransactions of the American Mathematical Society, 1935
1. In Newton's method for approximate evaluation of definite integrals the interval of integration, say (0, 1), is divided into a certain number n of equal parts and the integral of a given function f(x) is assumed to be approximately equal to the integral of the interpolation polynomial of degree n which at the points of subdivision has the same ...

Collapse of n Point Vortices, Formation of the Vortex Sheets and Transport of Passive Markers

open access: yesEnergies, 2021
In this paper, the motion of the n-vortex system as it collapses to a point in finite time is studied. The motion of vortices is described by the set of ordinary differential equations that we are able to solve analytically.

A Gravity Tensor and Gauge Equations for Newtonian Dynamics

open access: yesAxioms
It is revealed that the material derivative of a variable in gravity field is its directional derivative, from which and energy/complementary-energy conservations with exterior derivatives, two sets of gauge equations of Newton’s dynamic gravity field ...

Measuring Butt Log and Middle Log Volume of Eucalyptus Camaldulensis Using Different Methods in Erbil Province

open access: yesZanco Journal of Pure and Applied Sciences, 2022
The volume of each butt log and middle log of an individual tree at a 5-meter log length was calculated by using five different formulas (Newton`s, Smalian`s, Huber`s, Hossfeld`s, and Centroid method).
