Importance of the genetic algorithms (GA) usage in the investigation of an ultrashort pulse peak voltage in a printed circuit board (PCB) bus of autonomous navigation system (ANS) is highlighted. Trapezoidal ultrashort pulse propagation along the conductors of the PCB bus was simulated. Using GA an optimization of the 10 parameters for loads at the ends of the bus conductors was made. The optimization...
Importance of genetic algorithms (GA) usage in the investigation of an ultrashort pulse peak voltage in multiconductor structures of printed circuit boards (PCB) is highlighted. Trapezoidal ultrashort pulse propagation along the conductors of real PCB multiconductor bus was simulated. With the usage of GA, an optimization of the rise, top and fall durations of the ultrashort pulse was made by criteria...
Importance of research on specific aspects of ultrashort pulse propagation and voltage peak values localization along printed circuit board (PCB) multiconductor bus is highlighted. Simulation of a trapezoidal ultrashort pulse propagating along the conductors of the spacecraft autonomous navigation system bus with a different number of excited conductors and a variation of the whole ultrashort pulse...
Importance of the genetic algorithms (GA) usage in the investigation of an ultrashort pulse peak voltage in multiconductor structures of printed circuit boards (PCB) is highlighted. Trapezoidal ultrashort pulse propagation along the conductors of a real PCB multiconductor bus was simulated. Using GA an optimization of the whole ultrashort pulse duration and separately of the rise, top and fall durations...
Importance of research on specific aspects of ultrashort pulse propagation and signal maximum localization along the coupled lines is highlighted. Simulation of trapezoidal ultrashort pulse propagating in the turn of meander line with variation of its geometrical parameters: separation between conductors and their length has been done. Also the printed circuit board (PCB) bus of spacecraft autonomous...
The results of field experiments on the influence of application of phosphorite, glauconite, and zeolite to a leached chernozem demonstrated a decrease in exchangeable acidity of the soil, an increase in the contents of available phosphates of the first and second groups (Ca–P1 and Ca–P2) and water-soluble and exchangeable potassium, as well as the enhanced microflora activity in the rhizosphere,...
