From the classical antenna theory, characteristics of receiving can be analyzed by Thévenin equivalent circuit, but this circuit has limitations in determining dissipated power for a lossy antenna. In paper, Poynting streamline method is used to directly model as receiver where flow field energy around represented generating streamlines vector field. This provides better understanding true phys...

A method for solving the saturation equation for two-phase ow is presented. The method may be viewed as an operator splitting method or as an Eulerian-Lagrangian backtracking procedure or as a modiied method of characteristics. For each time step, the method consists of an advection step and a diiusion step. The advection step requires the tracking of streamlines locally around certain integrat...

Methanol limited fed-batch cultivation was applied for production of a plant derived beta-glucosidase by Pichia pastoris. The beta-glucosidase was recovered by expanded bed adsorption chromatography applied to the whole culture broth. The new Streamline Direct HST1 adsorbent was compared with Streamline SP. Higher bead density made it possible to operate at two times higher feedstock concentrat...

The investigation of the climate system is one of the most exciting areas of scientific research today. In the climate system, oceanic and atmospheric flows play a critical role. Because these flows are very complex in the span of temporal and spatial scales, effective computer visualization techniques are crucial to the analysis and understanding of the flows. However, the existing techniques ...

Abstract. The present study adresses the turbulent flow over a wavy surface by direct numerical simulation (DNS). Compared to classical channel flow the wavy surface structure adds a degree of complexity to the flow by inducing streamline curvature, flow separation and flow reattachment, thus leading to flow situations which are often present in relevant technical and geophysical applications. ...
