Numerical solution of the dielectrophoretic and travelling wave forces for interdigitated electrode arrays using the finite element method [PDF]

open access: yes, 2002
AC electrokinetics is the study of the movement of polarisable particles under the influence of AC electric fields. The fields are applied to a suspension of particles by planar microelectrode structures and one particular design, the interdigitated bar ...

Flow Separation Control in a Curved Diffuser with Rigid Traveling Wave Wall and Its Mechanism

open access: yesEnergies, 2019
Traveling wave wall is a useful method to suppress flow separation. However, the interaction between the traveling wave wall and unsteady separation flow is complex, which causes difficulty in discovering the corresponding mechanism.

Flow Separation in Rocket Nozzles, a Simple Criteria [PDF]

open access: yes, 2005
Cold and hot flow tests were conducted to investigate the flow separation in rocket nozzles. The results are presented. A separation data base including a wide range of literature data is established to evaluate the influence of propellant combination ...

Latent Variable Analysis and Signal Separation [PDF]

open access: yes, 2022
We assume a second-order source separation model where the observed multivariate time series is a linear mixture of latent, temporally uncorrelated time series with some components pure white noise.

The design and modeling of a lateral acoustic particle manipulator exhibiting quarter-wave operation [PDF]

open access: yes, 2008
Prior work [Petersson et al., 2004] has demonstrated the operation of a half-wave acoustic particle manipulator, whose forces act in the plane of a silicon substrate. In a half-wave device particles are directed to the centre of a channel. Devices acting

Large-eddy simulation of low-frequency unsteadiness in a turbulent shock-induced separation bubble [PDF]

open access: yes, 2009
The need for better understanding of the low-frequency unsteadiness observed in shock wave/turbulent boundary layer interactions has been driving research in this area for several decades.

P8.2 ARTERIAL WAVE REFLECTIONS: LOOKING BEYOND THE FIRST HARMONIC AND PRESSURE INFLECTION POINTS TO ASSESS LATE-SYSTOLIC VENTRICULAR LOADING

open access: yesArtery Research, 2015
Background: Late-systolic ventricular loading is associated with impaired relaxation and adverse remodeling. Standard indices of relative wave reflections such as augmentation index (AIx) and reflection magnitude (RM) from wave separation analysis blend ...

Mode Separation for Multimodal Ultrasonic Lamb Waves Using Dispersion Compensation and Independent Component Analysis of Forth-Order Cumulant

open access: yesApplied Sciences, 2019
Ultrasonic Lamb wave testing has been successfully applied in nondestructive testing. However, because of Lamb wave multimodal and dispersion characteristics, the received signals are often multimodal and overlapping, which makes them very complicated ...
