abstract this study was mainly conducted due to importance of plant manna and their production process regarding pharmaceutical use. therefore, the behaviourial characteristics of spittlebug poophilus nebulosus leth on alhagi persarum boiss & buhse camel thron plant in torbate jam region, khorasan razavi state were assessed during 2006 and 2007. the bug’s discharge after feeding on the camel th...

A simple numerical procedure has been implemented as a Matlab script to allow straightforward design of high speed, resistor loaded, differential amplifiers in modern CMOS processes. The amplifier, shown in Figure 1, exhibits device characteristics that dramatically depart from traditional square law characterisitics making designs based on hand calculations grossly inaccurate. The analytical f...

In this paper, a novel dual-polarized microstrip array antenna is proposed and its characterisitics are investigated. general, antennas have complicated element excitation methods feeding circuits. Both-sided microwave-integrated circuit (MIC) technology such as magic-T can simplify the structure. As integrates magic-Ts, elements two orthogonal feed circuits be arrenged on single-layer substrat...

The topic of this lecture is dimensionality reduction. Many problems have been efficiently solved in low dimensions, but very often the solution to low-dimensional spaces are impractical for high dimensional spaces because either space or running time is exponential in dimension. In order to address the curse of dimensionality, one technique is to map a set of points in a high dimensional space...
