The compensating choke plays an important role in many high-power industrial applications with reactive power compensation. Due to the high number of devices installed every year and EU’s efforts reduce energy demands our society, it is advisable maximize efficiency these devices. non-linearity magnetic core, requirement a linear operating characteristic, presence distributed air gap, this diff...

We consider the problem of providing a fair bandwidth allocation to each of n flows that share an outgoing link at a congested router. The buffer at the outgoing link is a simple FIFO, commonly shared by packets belonging to the n flows. We devise a simple packet dropping scheme, CHOKe, that discriminates against the flows which submit more packets/sec than is allowed by their fair share. By do...

The presence of a reasonable flowback system after fracturing is necessary condition for the high production shale gas wells. At present, optimization lacks relevant theoretical basis. Due to this lack, study established new method evaluating conductivity artificial fractures in shale, which can quantitatively characterize backflow, embedment, and fragmentation proppant during process. Then, me...

We are developing a small synthetic aperture radar (SAR) that is compatible with 100kg class satellite. A constellation of such small SAR satellites is promising for shot revisit time of earth observations. The SAR antenna is a deployable honeycomb panel antenna with slot array, that can be stowed compactly. RF instruments are on a satellite structure and feed through waveguides. RF signal feed...
