APPLICATION OF THE METHOD OF LINES FOR SOLVING ONE-DIMENSIONAL EQUATION OF PARABOLIC TYPE UNDER THE BOUBDARY CONDITIONS OF THE SECOND AND FIRS GENERA [PDF]

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2018
In the article an algorithm for solving a one-dimensional inhomogeneous parabolic equation is described under boundary conditions of the second kind at the beginning and of the first kind at the end of the interval. By introduction of a grid with respect

APPROXIMATION MODELS THE FORMATION PRESSURE ACCORDING TO GAS-DYNAMICS SURVEYS OF WELLS

open access: yesВестник Северо-Кавказского федерального университета, 2022
A convenient practical method for approximating of the formation pressure at an arbitrary point inside the reservoir is offered. The method uses measurements in neighboring wells which, unlike the classical methods of Lagrange and Newton, does not ...

A Computational Method with MAPLE for a Piecewise Polynomial Approximation to the Trigonometric Functions

open access: yesMathematical and Computational Applications, 2018
A complete MAPLE procedure is designed to effectively implement an algorithm for approximating trigonometric functions. The algorithm gives a piecewise polynomial approximation on an arbitrary interval, presenting a special partition that we can get its ...

More concerning the anelastic and subseismic approximations for low-frequency modes in stars

open access: yes, 2002
Two approximations, namely the subseismic approximation and the anelastic approximation, are presently used to filter out the acoustic modes when computing low frequency modes of a star (gravity modes or inertial modes).

Spectral Representation and Simulation of Fractional Brownian Motion

open access: yesComputation
This paper gives a new representation for the fractional Brownian motion that can be applied to simulate this self-similar random process in continuous time. Such a representation is based on the spectral form of mathematical description and the spectral

DEVELOPMENT OF A DISCRETE MATHEMATICAL MODEL OF THE HYDROTREATING DIESEL FUEL REACTOR

open access: yesСовременная наука и инновации, 2022
The article gives an example of the transformation of the initial mathematical model of the hydrotreating diesel fuel reactor which is a system of algebraic equations into its discrete analogue, using the method of "nets" (finite difference method).

Approximation of functions with linear positive operators which fix {1, φ} and {1, φ2}

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
In this manuscript, linear and positive operators described on bounded and unbounded intervals that fix the function sets {1, φ} and {1, φ2} such that φ ∈ C[0, 1] are presented. Then we present different types of operators by choosing different functions

Personalizing the Pediatric Hematology/Oncology Fellowship: Adapting Training for the Next Generation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT The pediatric hematology‐oncology fellowship training curriculum has not substantially changed since its inception. The first year of training is clinically focused, and the second and third years are devoted to scholarship. However, this current structure leaves many fellows less competitive in the current job market, resulting in ...

Nutritional and Behavioral Intervention for Long‐Term Childhood Acute Leukemia Survivors With Metabolic Syndrome

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Metabolic syndrome (MetS) is a common complication in survivors of childhood acute lymphoblastic and myeloid leukemia (AL), and a major risk factor for premature cardiovascular disease, type‐2‐diabetes, and metabolic dysfunction‐associated steatotic liver disease (MASLD).
