Decay rates for solutions of semilinear wave equations with a memory condition at the boundary

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2002
In this paper, we study the stability of solutions for semilinear wave equations whoseboundary condition includes a integral that represents the memory effect.

The relaxation effect of prolonged expiratory breathing

open access: yesMental Illness, 2018
This study was performed to confirm that autonomic nervous activity is affected by breathing speed. I hypothesized that prolonged expiratory breathing would promote parasympathetic dominance, whereas rapid breathing would promote sympathetic dominance ...

Simulation of Inhomogeneous Refractive Index Fields Induced by Hot Tailored Forming Components

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a simulation model for simulating inhomogeneous refractive index fields (IRIF) in hot‐forged components, accounting for thermal influences and complex geometries. Through this simulation, a priori knowledge about the propagation of the IRIF can be obtained, allowing for the positioning of the component or an optical measurement ...

A blow-up result for a viscoelastic system in $R^n

open access: yesElectronic Journal of Differential Equations, 2007
In this paper we consider a coupled system of nonlinear viscoelastic equations. Under suitable conditions on the initial data and the relaxation functions, we prove a finite-time blow-up result.

Current Trends and Future Perspective for Cold Spray Metal‐Ceramic Composites

open access: yesAdvanced Engineering Materials, EarlyView.
The use of cold spray (CS) technology for creating cermet deposits, combining ceramic and metallic components, is advancing rapidly. Cermets offer excellent temperature handling and erosion resistance for diverse applications. This review outlines the current state of the art, focusing on the deposition dynamics and strategies to optimize the ...

Cyclooxygenase-2 inhibition restored endothelium-mediated relaxation in old obese Zucker rat mesenteric arteries

open access: yesFrontiers in Physiology, 2010
Metabolic syndrome is associated with reduced endothelial vasodilator function. It is also associated with the induction of cyclooxygenase-2 (COX2), which produces vasoactive prostanoids.

Static and Dynamic Behavior of Novel Y‐Shaped Sandwich Beams Subjected to Compressive Loadings: Integration of Supervised Learning and Experimentation

open access: yesAdvanced Engineering Materials, EarlyView.
In this study, the mechanical response of Y‐shaped core sandwich beams under compressive loading is investigated, using deep feed‐forward neural networks (DFNNs) for predictive modeling. The DFNN model accurately captures stress–strain behavior, influenced by design parameters and loading rates.

Energy decay in a Timoshenko-type system for thermoelasticity of type III with distributed delay and past history

open access: yesElectronic Journal of Differential Equations, 2018
In this work, we consider a one-dimensional Timoshenko system of thermoelasticity of type III with past history and distributive delay. It is known that an arbitrarily small delay may be the source of instability.

Relaxation of convex functionals: the gap problem

open access: yesAnnales de l'Institut Henri Poincaré C, Analyse non linéaire, 2003
It is shown that the relaxed energy \mathcal{F}\left(u,A\right): = \inf \Big\{ \lim\!\! \inf_{n\rightarrow + \infty }\!\int \limits_{A}\! f(x,\nabla u_{n})dx:\{u_{n}\} \subset W_{\text{loc}}^{1,\beta }(A;\mathbb{R}^{d}),\, u_{n}\!\rightarrow\! u \text{ in }L^{1}(A;\mathbb{R}^{d}) \Big\},
