Polymer Dispersity Determination by Diffusion‐Ordered Spectroscopy (DOSY)

open access: yesMacromolecular Rapid Communications, EarlyView.
The use of DOSY‐NMR to determine the dispersity of polymer molar mass distributions is explored and correlations between NMR and size exclusion chromatography are determined. ABSTRACT The dispersity (Ð) of a polymer is one of its most important characteristics.

On the analyzing of bifurcation properties of the one‐dimensional Mackey–Glass model by using a generalized approach

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.

A highly accurate numerical method for solving boundary value problem of generalized Bagley‐Torvik equation

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Abstract Boundary Delay Systems and Application to Network Flow

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper investigates the well‐posedness and positivity of solutions to a class of delayed transport equations on a network. The material flow is delayed at the vertices and along the edges. The problem is reformulated as an abstract boundary delay equation, and well‐posedness is proved by using the Staffans–Weiss theory.

An Inverse Source Technique as a Preliminary Tool to Localize Persons in Indoor Spaces

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper considers an inverse heat source localization problem with applications to indoor person localization from temperature measurements. In particular, this inverse problem consists in the reconstruction of the intensity and position of heat sources from observed temperature data.
