... the 2DOF controller. Therefore, the vital control are robotics, conveyor belts, printing robustness and tracking performances may not be precisely presses/printers, textiles, antenna positioning, metal cutting guaranteed [12] -[ 14]. Sensorless speed control in the whole and metal forming machines speed range based on high frequency ...

... For application in these cases we develop an measurements of the electromagnetic field. Otherwise the optoelectronic telemetry system, for measurements, of the ELF sensor must be an antenna with extreme long dimensions. electric and magnetic fields, with small sensors in the So the limits are given in electric or magnetic field values measurement point and ...

... by the electric equipment and Another reason for the choice of the 50Ω characteristic conducted on the supply lines can be checked using a line impedance value is that monopole antennas have impedance stabilization network and a spectrum approximately the same characteristic impedance value, analyzer/EMC receiver. which guaranties an optimum match to the cable.- ...

... idle, it will do the transmission of RTS packet for the unicast flow. If the medium is busy, the node waits for d0= Reference distance for antenna far field random time and senses the carrier again. This happens till Typical value for d0= 1 to 10m in indoor environment. the packet gets transmitted ...

... is a correspondence In order to measure the power of the internal noise we between the parameters of the radiometer (W, T) and those have replaced the antenna of the measurement system with of the spectrum analyser. Thus, the measurement bandwidth an impedance of 50Ω. Figure III presents the results of the of the ...

... Volume 12, Number 3, 2012 ‚ Pure software receiver, in which the amplified and baseband sampling processes the complex signal and thus filtered signal received by the antenna is directly the two-channel ADC is needed. digitized by the ADC and then processed digitally. The described front-ends do not affect (distort) the signal There ...

... . We employ the two ray ground congestion detection threshold 1 € 1, i.e., the node starts reflection model [22], and a single omni-directional antenna adjusting its contention window when there are packets in at each sensor node. We load packets through a constant bit its buffer, and 2 € 3Qmax ...

... ]. The spatial diversity is still the fading, a solution would be using multiple transmit and accomplished under the influence of non-Gaussian noise [9 ], receive antennas [1 ], or alternative techniques, called the cooperative relaying being significantly better than cooperative diversity or cooperative communication [2]. direct transmission for low ...
