Developing Academic Vocabulary Independently (DAVI): A usability study

Second language (L2) learners preparing for academic study in English-speaking universities face major challenges in acquiring needed vocabulary that classroom study cannot fully overcome. According to recent second language vocabulary acquisition (SLVA) research, learners must deeply process target vocabulary in comprehensible contexts appropriately spaced over time. However, effective materials facilitating such encounters outside the classroom are rare. This paper reports the results of a usability study for the researcher\u27s learning system called DAVI (Developing Academic Vocabulary Independently), a system designed in light of the SLVA literature to help students independently acquire Academic Word List (AWL) vocabulary. DAVI uses Microsoft Excel-based vocabulary study pages that seek to encourage learners to manipulate target vocabulary in meaningful tasks, including Google searches within learner-friendly websites. Chinese students studying in an intensive English program at the high-intermediate level used a pilot version of DAVI during fall 2009, providing data to the teacher-researcher by such means as her observation of participants\u27 use of the system, learners\u27 DAVI assignment uploads, and a final questionnaire. These data were used to determine whether students thought DAVI benefited their vocabulary acquisition, how the way in which they used DAVI may have affected their vocabulary acquisition, and what vocabulary study methods they prefer. Results suggest that the present version of DAVI was too technologically challenging for participants and violated their preferences for more traditional methods of vocabulary study. Results also indicated web-based vocabulary development resources for students at this level are inadequate, suggesting that a Learner-Comprehensible corpus be built specifically to support AWL acquisition

Energy harvesting from vibrations with a nonlinear oscillator

In this paper we present a nonlinear electromagnetic energy harvesting device that has a broadly resonant response. The nonlinearity is generated by a particular arrangement of magnets in conjunction with an iron-cored stator. We show the resonant response of the system to both pure-tone excitation and narrow-band random excitation. In addition to the primary resonance, the super-harmonic resonances of the harvester are also investigated and we show that the corresponding mechanical up-conversion of the excitation frequency may be useful for energy harvesting. The harvester is modeled using a Duffing-type equation and the results compared to the experimental data.</jats:p

Application of antiresonance theory to helicopters

Antiresonance theory is the principle underlying nonresonant nodes in a structure, and covers both nonresonant nodes occurring naturally and those introduced by devices such as dynamic absorbers and antiresonant isolators. The dynamic antiresonant vibration isolator (DAVI) and the nodale module are examples of the applications of transfer antiresonances. It is shown that antiresonances are eigenvalues, and that they can be determined by matrix iteration. Applications of antiresonance theory to helicopter engineering problems, using the antiresonant eigenvalue equation are suggested
