To control the flow separation in the compressors, a novel pulsed jet concept without external energy injection is proposed. The new concept designs a slot in the middle of the blade and sets a micro device to switch the slot periodically. Such a structure is expected to generate a pulsed jet by the pressure difference between the pressure side and the suction side of the blade. In order to ana...

A high speed 3-D flow visualization system is synchronized with a 2-D particle image velocimetry (PIV) system to simultaneously capture instantaneous 3-D images with a 2-D PIV slice through the center of the measurement volume. Trials were performed on a zero pressure gradient (ZPG) turbulent boundary layer (Reθ ~ 4900) on the wall of a 2 ft x 2 ft open circuit wind tunnel. The experimental set...

This paper addresses the problem of identifying different flow environments from sparse data collected by wing strain sensors. Insects regularly perform this feat using a sparse ensemble of noisy strain sensors on their wing. First, we obtain strain data from numerical simulation of a Manduca sexta hawkmoth wing undergoing different flow environments. Our data-driven method learns low-dimension...

to low CSF levels and inability to meet pharmacokinetic/ pharmacodynamic targets, the patient was switched to levofloxacin on POD 17. Levofloxacin levels were determined on POD 20 and higher CSF levels were achieved. TDM results are shown in Table 1. The patient responded to therapy with slow neurological progress. The EVD was removed on POD 24, the catheter tip was not cultured and CSF culture...

A novel model-order reduction technique for the solution of the fine-scale equilibrium problem appearing in computational homogenization is presented. The reduced set of empirical shape functions is obtained using a partitioned version —that accounts for the elastic/inelastic character of the solution— of the Proper Orthogonal Decomposition (POD). On the other hand, it is shown that the standar...

In this paper we investigate the optimal control approach for the active control of the circular cylinder wake flow considered in the laminar regime (Re = 200). The objective is the minimization of the mean total drag where the control function is the time harmonic angular velocity of the rotating cylinder. When the Navier-Stokes equations are used as state equations, the discretization of the ...

REASONS FOR PERFORMING STUDY Palmar/plantar osteochondral disease (POD) is a common, debilitating condition in Thoroughbred racehorses; however, training- and racing-related factors associated with this disease are unknown. OBJECTIVES To determine horse-, racing- and training-related risk factors for POD. The general hypotheses were that early training and racing, and increased intensity of r...

Proper orthogonal decomposition (POD) has been widely realized as a tool for compressing fluctuating building pressure data in wind-engineering area. Modes are determined by eigen decomposition of data covariance matrix, and then truncation is applied to retain only the modes with the highest energy. However, as observed by S. Kho, C. Baker, R. Hoxey [Pod/arma reconstruction of the surface pres...

Establishment of anterior-posterior (a-p) polarity in the Caenorhabditis elegans embryo depends on filamentous (F-) actin. Previously, we isolated an F-actin-binding protein that was enriched in the anterior cortex of the one-cell embryo and was hypothesized to link developmental polarity to the actin cytoskeleton. Here, we identify this protein, POD-1, as a new member of the coronin family of ...
