Post-processing of PIV (particle image velocimetry) data typically contains three following stages: validation of the raw data, replacement of spurious and missing vectors, and some smoothing. A robust post-processing technique that carries out these steps simultaneously is proposed. The new all-in-one method (DCT-PLS), based on a penalized least squares approach (PLS), combines the use of the ...

In this paper we describe several network security protocols used by various components of CryptoNET architecture. The protocols are based on the concept of generic security objects and on wellestablished security standards and technologies. Distinctive features of our security protocols are: (1) they are complete in terms of their functionality, (2) they are easy to integrate with applications...

Particle image velocimetry (PIV) is a method used to measure the velocity field of a fluid flow. Traditionally, cross correlation algorithms are used to retrieve the flow velocity. Recently, a new method for PIV based on the L optimal mass transportation problem (OT-PIV), is introduced and analyzed in [Saumier, Khouider and Agueh, Optimal Transport for Particle Image Velocimetry, Comm. Math. Sc...

The strategic recombination of preformed coordination clusters in the presence of polymodal bridging ligands has successfully led to the characterisation of five new compounds of structural and magnetic interest. Indeed using the dinuclear complex [M2(H2O)(piv)4(Hpiv)4] (M = Co, Ni; Hpiv = pivalic acid) as starting material and reacting it with phenylhydroxamic acid (H2pha) has yielded the four...

Inadequate catheter securement is an underrecognized patient safety issue that contributes significantly to catheter-related complications, including dislodgment, occlusion, infiltration, and infection. Pooled data from prospective product trials at 83 hospitals compared tape to a standard peripheral intravenous (PIV) securement method with a PIV-specific catheter-stabilizing device (StatLock)....

The super-resolution PIV based on the recursive division of interrogation window has attracted interest recently. This approach needs careful error checks because results are largely affected by the pre-step displacements obtained by large interrogation windows. Hart (2000 Experiments in Fluids Vol.29-1) proposed the error check method by multiplication between correlation distributions of over...

In neuroscience, phase is assumed to contain more important information about the neural activity than amplitude. However, the most exploited feature in electroencephalogram (EEG) based brain computer interface (BCI) is the amplitude change, phase has been largely ignored, and only phase locking values (PLV) has been introduced in EEG classification recently. In this paper, we define phase inte...

This study is targeted at obtaining fluctuating characteristics of building wakes through measurement of unsteady velocity fields with time-resolved particle image velocimetry (PIV). Proper orthogonal decomposition is applied to the PIV data to identify low-dimensional substructures of the building wake. This leads to a more reliable estimation of the fluctuating ground-level length of the buil...

A method for the simultaneous measurement of velocity and passive scalar concentration fields by means of particle image velocimetry (PIV) and planar laser induced florescence (PLIF) techniques is described here. An application of the combined PIV-PLIF system is demonstrated by performing simultaneous velocity and concentration measurements in the near field of a turbulent jet mixing flow. The ...
