In this paper, I provide an analysis of Tohono O'odham vowel devoicing with respect to physiological explanation. There are three points in this paper. First, this paper provides data of devoicing (consonants and vowels) in Tohono O'odham. Second, analysis of devoicing in terms of subglottal pressure drop is provided. Third, the devoicing is accounted for(More)
This paper studies the relation between AC surface flashover voltages (FOVs) of an epoxy insulator and the surface resistivity in arc-decomposed SF<sub>6</sub> gas. It was found that as lowering the surface resistivity the FOV decreased and approached a constant value below the surface resistivity 109 ohm/square. The FOV characteristics and the discharge(More)
In this paper, we propose a Multimedia Scripting System (MSS) to support endangered language learning. With the use of advanced multimedia techniques and web 2.0 technology, MSS provides a user friendly environment to ensure that general users (without strong technical backgrounds) in an on-line community can effectively and collectively create multimedia(More)
