This investigation addresses the electrical properties of pentacene-based thin film transistors in air, dry air and high vacuum. A potential barrier model was applied to explain the gate dependent field effect mobility behavior. The results show the trap density in air higher than that in a vacuum.

In this study, an intelligent learning style aware diagnosis agent for computer-supported cooperative learning is proposed. Learners are first assigned to heterogeneous groups based on their learning styles questionnaire given right before the beginning of learning activities on the e-learning platform. The proposed diagnosis agent then scrutinizes each learner's learning portfolio on e-learning platform and automatically issues feedback messages in case some learner's behavior that is unfitted to his/her learning styles or devious argument on discussion board or wiki is detected. The Moodle, an open-source software e-learning platform, is used to establish the cooperative learning environment for this study. The experimental results reveal that the proposed learning style aware diagnosis agent indeed boosts the performance of the learners. (C) 2009 Wiley Periodicals, Inc.
