Phonetics attempts to describe and understand how speech is produced and perceived; phonology attempts to understand the patterning—in general, the behavior—of speech sounds in particular languages and in all languages. Is phonetics part of phonology? This straightforward question has received various answers at different points in the history of linguistics. In this paper I attempt to document...

in order to establish the appropriate methane fermentation technology for low strength wastewater, a 2.0 l egsb reactor was operated at 20â°c with 0.3 - 0.4 g cod/l of sucrose-based synthetic wastewater for 500 days. at the start up period, the reactor was operated in egsb mode with a 5 m/h up flow velocity by continuous effluent recirculation. however, the egsb reactor exhibited insufficient c...

background: the aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one ct dataset. materials and methods: for each of six patients with different thorax sizes, two sets of ct images were obtained in single-breath-hold inhale and exhale stages in the supine position. the ct images were then analyzed ...

Intermittent instability is commonly observed in switching power supplies during the design and development phase. It manifests as symmetrical period-doubling bifurcation in the time domain with long intermittent periods. Such intermittent operation is considered undesirable in practice and is usually avoided by appropriate adjustments of circuit parameters. This paper explores the mechanism an...
