Fountain codes are widely employed to improve reliability and efficiency in wireless communication systems due their simple coding mechanisms. In this letter, we propose an opportunistic decoding recoding mechanism with coordinative routing algorithm for fountain the expected transmission counts (ETX) performance reduce computational complexity of at each relay multi-hop sensor networks. The fu...

Abstract The relationship between thresholds of free radical generation and atomization under ultrasound exposure was investigated to elucidate the mechanisms ultrasonic atomization. In experiments gradually increase transducer driving voltage, generation, a quick transition water surface shape from protuberance fountain, had same threshold. using acoustic loading conditions with different shap...
