A Teacher’S Journey Integrating Engineering In A Middle School Science Classroom And The Effects On Student Attitudes (Rtp), Christie Jilek, Noah Salzman

Electrical and Computer Engineering Faculty Publications and Presentations

As teachers are encouraged to help students become problem solvers, incorporating engineering methods into the classroom has become an important theme of conversation. The purpose of this paper is to explore the change in student attitudes when integrating engineering instruction within a middle school science classroom. This study involves 8th grade students located within a single science teacher’s classroom exploring the integration of engineering activities and content for the first time. We assessed student attitudes using a survey constructed by the Friday Institute¹ aimed measuring perception toward STEM related fields and study. Surveys were administered before and after engineering …

Connecting Hardware And Software In A Middle School Engineering Outreach Effort-Rtp, Noah Salzman, Sin Ming Loo

Electrical and Computer Engineering Faculty Publications and Presentations

Recent years have seen tremendous growth in outreach programs aimed at bringing computer programming to children and young adults via in-class and extracurricular coding activities. Programs such as the Hour of Code and Girls who Code have introduced millions of young people to programming around the world. For this study, we explored how combining programming with interactive electronics hardware can create a more engaging and dynamic learning environment for some students than what programming alone can achieve.

In this paper, we describe an electrical engineering outreach effort in collaboration with the technology and engineering teacher at a local middle school. …

Head Wave Correlations In Ambient Noise, John Thomas Gebbie, Martin Siderius

Electrical and Computer Engineering Faculty Publications and Presentations

Ambient ocean noise is processed with a vertical line array to reveal coherent time-separated arrivals suggesting the presence of head wave multipath propagation. Head waves, which are critically propagating water waves created by seabed waves traveling parallel to the water-sediment interface, can propagate faster than water-only waves. Such eigenrays are much weaker than water-only eigenrays, and are often completely overshadowed by them. Surface-generated noise is different whereby it amplifies the coherence between head waves and critically propagating water-only waves, which is measured by cross-correlating critically steered beams. This phenomenon is demonstrated both experimentally and with a full wave simulation.

A Brief Review Of Speaker Recognition Technology, Clark D. Shaver, John M. Acken

Electrical and Computer Engineering Faculty Publications and Presentations

This paper reviews the development of speaker recognition systems from pre-computing days to current trends. Advances in various sciences which have allowed autonomous speaker recognition systems to become a practical means of identity authentication are also reviewed.
