Abstract In this research article, we examined the Darcy-Forchheimer 3D in bioconvection Casson nanofluid flow light of a whirling disk with Arrhenius Activation Energy and thermal Radiation. The governing equations are converted to similarity solved afterward by utilizing Homotopy Analysis Method on behalf several controlling parameters. findings from study show, that radial velocity tangentia...

Future Unmanned Air Vehicles (UAV) and Micro Air Vehicles (MAV) will fly in urban areas and very close to obstacles. We built a miniature (35 cm, 0.840 kg) electrically-powered aircraft which uses a motion-sensing visual system to follow terrain and avoid obstacles. Signals from the 20-photoreceptor onboard eye are processed by 19 custom Elementary Motion Detection (EMD) circuits which are deri...

Abstract The moiré engineering of two-dimensional magnets opens unprecedented opportunities to design novel magnetic states with promises for spintronic device applications. possibility stabilizing skyrmions in these materials without chiral spin-orbit couplings or dipolar interactions is yet be explored. Here, we investigate the formation and control ground state topological spin textures (TST...
