Automated Fixture Design For A Rapid Machining Process, Wutthigrai Boonsuk, Matthew C. Frank
Automated Fixture Design For A Rapid Machining Process, Wutthigrai Boonsuk, Matthew C. Frank
Faculty Research & Creative Activity
Rapid prototyping techniques for CNC machining have been developed in an effort to produce functional prototypes in appropriate materials. One of the major challenges for rapid machining is to develop an automatic fixturing system for securing the part during the machining process. The method proposed in this paper is the use of sacrificial fixturing, similar to the support structures in existing rapid processes like Stereolithography. During the machining process, sacrificial supports emerge incrementally and, at the end of the process, are the only entities connecting the part to the stock material. This paper presents methodologies for the design of sacrificial …

Algorithms To Automate Estimation Of Time Codes For Captioning Digital Media, Daniel P. Harvey Ii, Peter Ping Liu
Algorithms To Automate Estimation Of Time Codes For Captioning Digital Media, Daniel P. Harvey Ii, Peter Ping Liu
Peter Ping Liu
Procedures were developed to partially automate the captioning process by estimating caption time codes using plain-text transcripts and audio recordings. Signal analysis is performed on the audio to measure pause location and duration, zero crossing rate (ZCR), and obtain frequency domain data. Algorithms were developed to match pauses in the audio to the ends of sentences in the transcript based on the observation that pause durations are greater at ends of sentences than within sentences. We have observed that ZCR peaks correspond to consonants in speech and that continuous wavelet transforms (CWT) work well for distinguishing between groups of consonants. …
