Acoustic wave propagation due to the breakage or slippage of reinforced wire in water-filled prestressed concrete cylinder pipe (PCCP) attracts interest in non-destructive pipe testing. Current practice of acoustic emission (AE) detection and wire-break related events (WRE) recognition ... En savoir plus
The experience of the eruption in Montserrat in 1997 has shown that the resistance of openings of buildings represents a crucial factor in the evaluation of vulnerability to the stresses caused by pyroclastic flows, although the static nature of the building itself is not compromised. ...

The mitral valve apparatus is a complex and refined mechanism located between the left atrium and the left ventricle of the heart which can manifest various kinds of pathologies. In order to support identification of potentially critical conditions resulting from some typical ... En savoir plus
Condenser microphones will have an electrical output for any displacement of the membrane relative to the back plate, which is usually bound to the microphone housing. For the typical use case, a pressure input will create a pressure difference across the membrane, which causes a ... En savoir plus
Valves are widely used to control fluid flow in various engineering applications. It’s crucial to study the flow characteristics inside the valve and the fluid-structure interaction between the fluid and valve’s sleeve for design, optimization and improvement of valves. However, because ... En savoir plus
The expression <em>adaptive optics</em> was initially termed for the technology used in the telescopes to deform the mirrors to allow for phase correction of the incoming light. Soon, the adaptive optics was also implemented in microscopes, optical communication systems and ... En savoir plus
This study creates a 2D fluid-structure interaction (FSI) model to study the effect of magnetic field and particle aspect ratio on the period of rotation and symmetry of ellipsoidal paramagnetic particles. The results show that the magnetic field strength has a significant effect on the ... En savoir plus
Flexible and semi-rigid polyurethane foams are widely used as noise and vibration damping materials. Their porous random microstructure is composed of a visco-elastic frame structure with an interstitial fluid, normally air, filling the voids. The viscoelasticity of the foams is due to ...

As a general definition, the presence of any repeated motion after a regular interval of time is known as vibrations. The basic theory of vibrations is described by the system of forces acting on a moveable and deformable body. The natural phenomena existing in the universe such as ... En savoir plus
Solenoid valves control fluid flow by using the passage of an electric current to produce a magnetic field that controls the displacement of a pre-tensioned plunger. As the electric current increases, the induced force causes the plunger to move upward against the force exerted by a ... En savoir plus
