Sound Waves in the Atmosphere Generated by a Small Earthquake

A model of the sound generated by breaking waves

The sound produced from a single bubble, oscillating atits breathing mode frequency, and the bubble size distribution are used to model the sound produced by breaking waves. The data of Medwin and Daniel [$. Acoust. Soc. Am. 88, 408-412 ( 1990} ] is used to evaluate the performance ofthe model. The model generates a damped sinusoidal pulse for every bubble formed, as calculated from the bubble ...

on the teacher-generated v.s. leaner-generated noticing-the-gap activities in language classes

abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
