We apply the Proper Orthogonal Decomposition (POD) method for efficient simulation of several scenarios undergone by Micro-Electro-Mechanical-Systems, involving nonlinearites geometric and electrostatic nature. The former type nonlinearity, associated to large displacements devices, leads polynomial terms up cubic order that are reduced through exact projection onto a low-dimensional subspace s...

Controlling flow in an unsteady separating flow requires accurate information about the surface forces and the effect that vortical structures in the flow field have on those surface forces. A correlation between vortex passage and surface pressure is defined to determine appropriate locations for sensors on the surface of a square cylinder for control feedback. Data are generated using a large...

We study the viscous spatial linear stability characteristics of the time-averaged flow in turbulent subsonic jets issuing from serrated (chevroned) nozzles, and compare them to analogous round jet results. Linear parabolized stability equations (PSE) are used in the calculations to account for the non-parallel base flow. By exploiting the symmetries of the mean flow due to the regular arrangem...

In this paper, we introduce a reduced order model (ROM) for the propagation of nonlinear multi-directional ocean wave-fields. The ROM relies on Galerkin projection Zakharov equations embedded in high-order spectral (HOS) method, which describes evolution waves. dominant flow features wave are computed from proper orthogonal decomposition (POD) and these modes used projection. HOS scheme to comp...

OBJECTIVES The purpose of this study was to investigate the incidence, predictive factors, and effect of post-operative delirium (POD) among patients treated by transcatheter aortic valve replacement (TAVR). BACKGROUND Patients undergoing operations that involve valve replacement appear at higher risk of POD than patients subjected to coronary artery bypass surgery alone. In patients with sev...

this paper presents new sensitivity-based methods for detection of structural damage using incomplete noisy modal data. these methods are based on the first-order derivative of modal parameters. changes of natural frequency do not usually provide spatial information on the structural damage. they are also not sensitive to the local damage. in this paper, a new sensitivity function is proposed u...

Electrophotographic printers are required to provide photograph quality printing with the rapid implementation of color in an office environment and meet the needs for POD*1). The printing quality of conventional color electrophotographic printers is no longer capable of adequately satisfying the needs of customers. Furthermore, printing systems with a high resolution are used in the pre-press ...

The production of the H(2)O(2)-generating enzyme pyranose oxidase (POD) (EC 1.1.3.10) (synonym, glucose 2-oxidase), two ligninolytic peroxidases, and laccase in wood decayed by three white rot fungi was investigated by correlated biochemical, immunological, and transmission electron microscopic techniques. Enzyme activities were assayed in extracts from decayed birch wood blocks obtained by a n...

BACKGROUND Hospital-acquired pneumonia (HAP) is a common complication after abdominal surgery. The aim of this study was to evaluate the role of procalcitonin (PCT) and C-reactive protein (CRP) as early biomarkers for the diagnosis of postoperative HAP after abdominal surgery. METHODS This study was conducted on 100 patients undergoing abdominal surgery. White blood cell counts, highest body ...
