Proper orthogonal decomposition (POD) method has been successfully used in the reduced-order modeling of complex systems. In this paper, we extend the applications of POD method, i.e., combine the classical finite volume element (FVE) method with the POD method to obtain a reduced-order FVE formulation with lower dimensions and sufficiently high accuracy for two-dimensional solute transport pro...

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...

Stomatal density of pods and leaves were determined for six commercial snap bean cultivars (Phaseolus vulgaris L. ‘Evergreen’, ‘Hystyle’, Labrador’, ‘Tenderlake’, ‘Top Crop’, and ‘Venture’) grown at three planting dates, in an attempt to find morphological traits that could be related to cultivar differences in pod Ca concentration. Snap beans were planted three times at ≈1-week intervals begin...

This report focuses on improving the stability as well as the approximation properties of Reduced Order Models (ROM) based on Proper Orthogonal Decomposition (POD). The ROM is obtained by seeking a solution belonging to the POD subspace and that at the same time minimizes the Navier-Stokes residuals. We propose a modified ROM that directly incorporates the pressure term in the model. The ROM is...

Zusammenfassung Die vorliegende Masterarbeit behandelt die numerische Lösung linear-quadratischer Optimalsteuerungsprobleme mittels " optimality system POD " (OSPOD) und POD a-posteriori Fehlerschätzer. Ausgangspunkt ist die Modellreduktion mit einem klassischen POD Galerkin Ansatz, wobei die Güte des reduzierten Modells durch den a-posteriori Fehler in der Steuerung sehr gut geschätzt werden k...

Introduction: Obesity is rapidly becoming a worldwide problem affecting the reproductive system. Some studies have shown the relationship between obesity and infertility, but until now it remains controversial. The present study was undertaken to investigate the effects of a specific high-fat diet on the male rat reproductive performances. Materials and Methods: Male Wistar rats were fed either...

BACKGROUND Transient hypocalcemia is one of the postoperative complications of thyroidectomy for thyroid nodules, and intraoperative and postoperative intact parathyroid hormone (iPTH) assays are used to predict postoperative hypocalcemia. OBJECTIVES The current study was conducted to evaluate a single serum iPTH measurement on postoperative day 1 (POD 1) as a means to predict hypocalcemia oc...
