Aim: To assess which modality (POD – 2 removal Vs POD -4 removal of catheter) has overall benefits for the patient undergoing TURP. Methodology: we performed this prospective study on 68 patients From January 2011 to January 2014, The patients were divided into two groups. Group I included patients in whom the catheter was removed on POD – 2 and Group – II included patients in whom catheters we...

In this article, a coupled computational framework is presented for the numerical simulation of mass transfer under the effects of natural convection phenomena in a field contains water-copper Nano-fluid. This CFD model is build up based on accurate algorithms for spatial derivatives and time integration. The spatial derivatives have been calculated using first order upwind and second order cen...

Preview measurements of the inflow by turbine-mounted lidar systems can be used to optimise wind turbine performance or alleviate structural loads. However, nacelle-mounted lidars suffer data losses due unfavourable environmental conditions and laser beam obstruction rotating blades. Here, we apply proper orthogonal decomposition (POD) simulated line-of-sight speed a scanning obtained from two ...

Isogeometric Analysis (IGA) is used in combination with proper orthogonal decomposition (POD) for model order reduction of the time parameterized acoustic wave equations. We propose a fully discrete IGA-Newmark-POD approximation and we analyze the associated numerical error, which features three components due to spatial discretization by IGA, time discretization with the Newmark scheme, and mo...

This paper presents a method for inviscid airfoil analysis and design optimization that uses reduced order models to reduce the cost of computation. Strong emphasis is placed on obtaining reasonably accurate solutions to the Euler equations with computational costs which are far lower than those required by traditional Computational Fluid Dynamics (CFD) techniques. The design procedure presente...

The POD makes possible to reduce the complete highdimensional acoustic field to a low-dimensional subspace where different modes are identified and let reconstruct in a simple way a high percentage of the variance of the field. Rotating modes are instabilities which are commonly observed in swirling flows. Such modes can appear under both cold and reacting conditions but that they have differen...

Proper orthogonal decompositons (POD) have been used to systematically extract the most energetic modes while centroidal Voronoi tessellations has been used to systematically extract best representatives. We combine the ideas of CVT and POD into a hybird method for model reduction. The optimality of such an approach and various practical implementation strategies are discussed.
