English as Foreign Language (EFL) learners frequently encounter difficulties in applying disparate strategies or techniques in order to recall the unfamiliar vocabularies. Language learners use vocabulary as a mean of reception and expression to acquire and convey meaning. Therefore, being able to remember new and unfamiliar words is outstanding for their success. Allen (1999) states that ldquo;vocabulary instruction is one of those educational arenas in which research and best practice are ...

As novel construction materials become more economically and technically available throughout theglobe, the structures become more complex. Therefore, an unexpected failure of these structures causescatastrophic economical and fatal losses. Over the past decades, a number of vibration based damagedetection techniques have been developed to avoid unexpected failure in structures. These damagedetection methods identify presence, location and magnitude of developed damage in the ...
This paper presents the application of a novel vibration-based technique for detecting fatiguecracks in structures. The method utilizes the empirical mode decomposition method (EMD) toestablish an effective energy-based damage index. To investigate the feasibility of the method,fatigue cracks of different sizes were introduced in an aluminum beam subjected to a cyclic loadunder a three-point bending configuration. The vibration signals corresponding to the healthyand the damaged states of the ...
