abstract area-reduction method is one of the most common experimental methods that determines the sediment distribution in reservoirs. in this method, reservoirs are geometrically divided into four types. for all reservoir types, parameters are achieved based on a limited number of reservoirs which leads to large scale errors for prediction of this method. so suitable parameters can be achieved...

Maximum power feed efficiency of MIMO antenna with intensive mutual coupling on handset is achieved not by match or conjugate match source impedance configuration, but by the source impedance that introduces small reflection between the sources and the antenna network to reduce the power transmitted from the one source and absorbed by other sources. A novel model for calculating the absorbed po...

introduction: human resources information management as one of the valuable and modern achievement is the biggest challenge that managers are faced with and there is a deep believe on application and practical execution of modern managerial approaches in human resource area such as european foundation for quality management (efqm) model can cause performance improvement and organizational effic...

a floating polymer-supported photocatalyst based on polystyrene impregnated with titaniumdioxide particles was developed using a facile solvent-cast method at ambient temperature. the preparedphotocatalysts were characterized by x-ray diffraction, scanning electron microscopy and fourier transforminfrared spectroscopy. the photocatalytic activity of the developed photocatalysts was investigated...

Using mariculture data from China’s nine coastal provinces from 2003 to 2015, this paper first evaluates the technical efficiency through data envelopment analysis (DEA). Then, this paper analyses the spatial spillover effect of technical efficiency and its influencing factors with a spatial panel Durbin model (SDM). The results indicate that there are obvious regional differences in the techni...
