Direct Ink Writing of Carbon‐Based Electrofluids for Soft Electrical Component Manufacturing

Advanced Materials Technologies, Volume 10, Issue 16, August 21, 2025.
This work explores the manufacturing of Electrofluids (EFs), conductive particle suspensions that flow while maintaining conductivity, for soft electrical components. Using Direct Ink Writing (DIW), patterned EFs achieve enhanced performance, including a 800% sensitivity boost in strain gauges. Through rheological studies, a printability map is created

Analysis of the contact problem functionally graded layer placed on a Pasternak foundation

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 8, August 2025.
Abstract This paper uses analytical and numerical methods to investigate the frictionless receding contact problem of two layers, one functionally graded (FG), loaded by a circular rigid block and resting on a Pasternak foundation. The upper layer loaded by the circular punch has homogeneous properties and contains a single shear modulus, while the ...

Context-Aware Gossip-Based Protocol for Internet of Things Applications

Sensors, 2018
This paper proposes a gossip-based protocol that utilises a multi-factor weighting function (MFWF) that takes several parameters into account: residual energy, Chebyshev distances to neighbouring nodes and the sink node, node density, and message ...

A novel approach for solving weakly singular fractional integro-differential equations

Partial Differential Equations in Applied Mathematics
In this essay, we introduce a novel idea to tackle the challenges of fractional integro-differential equations (FIDEs) featuring weakly singular kernels (WSKs). New idea leverages B-splines for solving such equations, offering a robust numerical solution

Two Schemes Based on the Collocation Method Using Müntz–Legendre Wavelets for Solving the Fractional Bratu Equation

Axioms
Our goal in this work is to solve the fractional Bratu equation, where the fractional derivative is of the Caputo type. As we know, the nonlinearity and derivative of the fractional type are two challenging subjects in solving various equations.

Internality of Two-Measure-Based Generalized Gauss Quadrature Rules for Modified Chebyshev Measures II

Mathematics
Gaussian quadrature rules are commonly used to approximate integrals with respect to a non-negative measure dσ^. It is important to be able to estimate the quadrature error in the Gaussian rule used.
