In attempts to broaden participation in computing, the computer science education community has developed a wide variety of outreach activities to encourage students of different ages to learn computational thinking techniques and to develop an interest in computer science. In their recent surveys of the CSed literature, Decker, McGill, and Settle identify(More)
Computer science, particularly in the United States, continues to suffer from underrepresentation by women and students of color. Increasingly, evidence suggests that we need to approach student perceptions of computer science and self perceptions of "who does computer science" before college, at ages in which students have not yet formed(More)
Piezocomposite materials have significantly improved the performance of ultrasonic testing. When compared to monolithic piezoceramics, the coupling factor is higher and the acoustic impedance is lower. Both of these factors contribute to improved sensitivity and bandwidth. More recently, single-crystal piezoelectric materials are being developed. These new(More)
