In this study, the efficiencies of seed priming with electromagnetic field (0, 2, 4, and 6 mT; 30 minutes daily for 3 days) were investigated in Salvia nemorosa. The exposure to electromagnetic filed led to significant increases in biomass accumulation (mean=53.6 %). Electromagnetic filed treatments significantly increased K, Ca, Mg, and Fe contents in leaves by mean 39.5 %. The electromagnetic...

Electromagnetic forming (EMF) is a kind of high-speed technology that can be useful for materials like aluminum. EMF helps to overcome the limitations traditional forming. Due this ability, use in automotive applications has risen recent years. The application finite element software packages such as ANSYS 22 gives numerical modelling capabilities simulate process and design process. Hence, aim...

We generate simulated (I)SAR imagery of a number of ground vehicles with the program Spectre [1] and validate these against turntable (I)SAR imagery from trials. Spectre employs a Physical Optics / Geometrical Optics (PO-GO) or shooting-bouncing-ray high frequency physics model. This approach is employed as standard for high-frequency electromagnetic scattering calculations from large complex b...
