On Convergence of Quadrature Methods for the Lipschitz-Continuous Functions [PDF]

, 2000
In this article we present a new approach to quadrature methods where any quadrature formula is generated by a discontinuous function whose jumps are quadrature weights.

Explicit Methods for Inverse Source Identification in Transient Diffusion via Truncated Eigenfunction Regularization of Temperature Measurements

Heat Transfer, EarlyView.
ABSTRACT This work presents and compares two explicit approaches for estimating space‐ and time‐dependent source terms in parabolic diffusion equations, derived from analytical solutions obtained through the Classical Integral Transform Technique (CITT).

Differential quadrature for multi-dimensional problems

, 1984
The technique of differential quadrature for the solution of partial differential equations, introduced by Bellman et al., is extended and generalized to encompass partial differential equations involving multiple space variables.

Design and Performance Analysis of Differential Chaos Shift Keying System With Dual-Index Modulation

IEEE Access, 2019
In order to sufficiently utilize the time slot resources of the recently proposed pulse-position-modulation differential chaos shift keying (PPM-DCSK), we apply dual-index modulation to differential chaos shift keying and then present two differential ...

MRI Proton Density Fat Fraction as a Biomarker of Marrow Recovery Following Organ‐Sparing Total Marrow Irradiation in Sickle Cell Disease

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Noninvasive quantitative assessment of marrow recovery after curative therapies such as total marrow irradiation (TMI) and bone marrow transplantation (BMT) remain poorly defined, particularly in sickle cell disease (SCD). Purpose To evaluate MRI‐derived proton density fat fraction (PDFF) as a biomarker of marrow recovery following ...

Design of quadrature rules for Müntz and Müntz-logarithmic polynomials using monomial transformation [PDF]

, 2009
A method for constructing the exact quadratures for Müntz and Müntz-logarithmic polynomials is presented. The algorithm does permit to anticipate the precision (machine precision) of the numerical integration of Müntz-logarithmic polynomials in terms of ...

A Modified Generalized Laguerre-Gauss Collocation Method for Fractional Neutral Functional-Differential Equations on the Half-Line

Abstract and Applied Analysis, 2014
The modified generalized Laguerre-Gauss collocation (MGLC) method is applied to obtain an approximate solution of fractional neutral functional-differential equations with proportional delays on the half-line.

Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

Journal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...

A high-accuracy differential quadrature method with optimized spline basis for Burgers’ equation

Mathematical and Computer Modelling of Dynamical Systems
In this study, a new numerical approach is presented by combining the differential quadrature method with particle swarm optimization for an efficient solution of nonlinear partial differential equations. The proposed methodology is illustrated using the
