Space‐Time Boundary Elements on Graded Meshes for 3D Elastodynamics

International Journal for Numerical Methods in Engineering, Volume 126, Issue 20, 30 October 2025.
ABSTRACT The solution to the elastodynamic equations in the exterior of a polygonal or polyhedral domain or a screen exhibits singularities at corners and edges. This paper presents a space‐time boundary element method in 3D on algebraically graded meshes to resolve these singularities, based on recently obtained error estimates for the weakly singular

Robust Mammogram Denoising Under Extreme Impulse Noise via FLBMF‐Selective Median‐TV Hybrid Scheme

Engineering Reports, Volume 7, Issue 10, October 2025.
(a–g) Original, degraded, and denoised DDSM Mammogram A_0042_1.RIGHT_CC.jpg, S, and P noise densities: 10%, 20%, 40%, 60%, 70%, 80%, and 90%. ABSTRACT Critical for the early detection and precise diagnosis of breast cancer, mammogram imaging risks encountering extreme impulse noise which, in some cases, occurs at levels between 60% and 90%.

Forced Convection of Carreau Hybrid Nanofluid in a Modified T‐Shaped Cavity Under Inclined MHD and Radiation Effects

Engineering Reports, Volume 7, Issue 10, October 2025.
The 2D, steady, laminar forced convection of a Carreau hybrid nanofluid (MgO–Ag/water) in a modified T‐shaped cavity with two outlets and a bottom inlet is investigated numerically in current work. The cold nanofluid enters from the inlet at the bottom with Tc$$ {T}_c $$ and velocity uc$$ {u}_c $$, while the vertical L‐shaped walls (W1$$ {W}_1 $$ and ...

Performance Analysis of Pulse Detonation Micro Gas Turbines Under Typical Operating Conditions

Energy Science &Engineering, Volume 13, Issue 10, Page 4690-4703, October 2025.
ABSTRACT Considering the benefits of pulse detonation combustion, including low entropy increase, high cycle thermal efficiency, and self‐pressurization, a performance calculation model for a pulse detonation micro gas turbine was established using methane as fuel. The study primarily investigated the impact of component parameters, ambient conditions,
