The method of ensemble averaging (EA), commonly used to improve signal-to-noise ratio (SNR) in evoked potential measurements, loses potentially useful information regarding response variability across trials. Due to the usually low SNR, it is difficult to extract the response from individual trials. The present paper describes an adaptive signal enhancer(More)
A B S T R A C T New computing platforms have greatly increased the demand for programmers , but learning to program remains a big challenge. Program synthesis techniques have the potential to revolutionize programming by making it more accessible. In this dissertation, I present three systems , AutoProf, FlashFill, and Storyboard Programming Tool (Spt),(More)
Data Structure is a core course for students majored in Computer Science, and experiment of Data Structure is an important process for learning basic Computer Science concepts. To mastering it better, a visible experimental Data Structure framework was designed for that purpose; students who make uses of this framework could complete the visible Data(More)
The maximum length sequence (MLS) technique is applied to improve data collection of a clinically important long latency visual potential. Given a limited time for measuring the response and with low number of stimulus presentation, the MLS technique exceeded the conventional method of ensemble averaging in attaining a higher signal-to-noise ratio (SNR).(More)
A biomembrane was developed from pig peritoneum treated with 0.65% glutaraldehyde. This was evaluated for use as a dural substitute in an animal model and in a patient population. After being treated with the glutaraldehyde solution, the biomembrane lost its antigenicity while its collagen underwent an irreversible cross-linking reaction, causing it to(More)
