Developing RFID library systems in the direction of integration into the global identification system EPC [PDF]

open access: yesarXiv, 2018
The possibility of modification of the regulatory framework of RFID library systems in the direction of integration into the EPCglobal Network, based on existing harmonized standards of RFID technology. It is shown that this approach to the formation of the regulatory framework will improve the availability of RFID technology for libraries and ...

Hemodynamics in Cerebral Aneurysms and Parent Arteries With Incompletely Expanded Flow Diverter Stents

open access: yesInternational Journal for Numerical Methods in Biomedical Engineering, Volume 41, Issue 4, April 2025.
Incomplete stent expansion (IncompSE) during flow diverter stent (FDS) deployment may lead to unfavorable hemodynamic changes, increasing risks of complications and incomplete aneurysm occlusion. Using computational fluid dynamics (CFD), we analyzed three basic aneurysm models under various incompSEs. IncompSE resulted in higher volume flow, wall shear

Local solutions for a Timoshenko system in noncylindrical domains

open access: yesPortugaliae Mathematica, 2008
In this paper we study a Timoshenko system modeling transverse vibrations of thin elastic beams in a moving boundary domain. Existence and uniqueness of a local solution is proved by using Faedo–Galerkin approximation.

A New Method to Assess the Possibility of Brittle Failure of Rock Induced by Deep Excavations

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 6, Page 1725-1746, 25 April 2025.
ABSTRACT Spalling and rockburst are severe criticalities that can emerge while excavating deep tunnels in rock masses under heavy natural stress states. Here, rock brittle failure can induce massive releases of the energy stored during the excavation and dangerous projections of rock blocks into the opening.

Exponential Decay in a Timoshenko-type System of Thermoelasticity of Type III with Frictional versus Viscoelatic Damping and Delay [PDF]

open access: yesarXiv, 2018
In this work, a Timoshenko system of type III of thermoelasticity with frictional versus viscoelastic under Dirichlet-Dirichlet-Neumann boundary conditions was considered. By exploiting energy method to produce a suitable Lyapunov functional, we establish the global existence, exponential decay of Type-III case.

Multiobjective QFT Control as Enabler for Wind Turbines With Soft‐Soft Towers

open access: yesWind Energy, Volume 28, Issue 4, April 2025.
ABSTRACT Wind energy tendency towards larger rotors and higher hub heights reach a limit when wind turbine pitch controller bandwidth is constrained by the first tower fore‐aft bending moment. While most manufacturers try to find a workaround with alternative nonstandard tower designs, this paper presents a control solution based on quantitative ...

A size‐dependent model of strain gradient elastic laminated micro‐beams with a weak adhesive layer

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 4, April 2025.
Abstract A size‐dependent model for a laminated micro‐beam with a soft adhesive is developed in the framework of strain gradient elasticity theory. The layered beam is constituted by two Euler–Bernoulli strain gradient elastic isotropic beams, joined through a strain gradient spring‐type contact law at the adhesive level.
