Science and Engineering Fair
They would serve as a “risk barometer” by monitoring the emotional state of a household in real time. As such, domes- tic violence could be detected in its early phases. Ms. Liu developed a tiered neural network architecture based on nontext prosodic, acoustic, statistical, and spectral features of speech and then evaluated her algorithms using a library of spoken speech with emotion. The project abstract is avail- able at bit.ly/2NQkCsb. Ms Liu also received the Samvid Education Foundation’s Geno Third Place Award.
Honorable mention went to Rohan Ahluwalia (Biomedical Engineering Category), also from Westview High School and also mentored by teacher Debbie Cooper. Mr. Ahluwa- lia’s project was “A Fully Functional Closed- Loop System Using Ultrasound Imaging to Automatically Detect Lipo-
hypertrophy in People with Insulin-Dependent Diabetes.” Lipohypertrophy is an accumulation of fat under the skin that occurs in diabetics who self-administer multiple daily injections. Early detection is key to preventing a much more painful and unsightly condition. Mr. Ahluwalia developed an edge-detection algorithm that can discern early-stage lipo- hypertrophy using ultrasound images that cannot be other- wise detected by sight or feel. Using a database of ultrasound images, his algorithm was determined to be correct 85% of the time. Human trials of his device also proved successful. Mr. Ahluwalia abstract is available at bit.ly/2wPbRHF.
The judges look forward to the many great accomplishments and leadership from the many talented youth who partici- pated in the Intel ISEF.
Become a Member of the Acoustical Society of America
The Acoustical Society of America (ASA) invites individuals with a strong interest in any aspect of acoustics including (but not limited to) physical, engineering, oceanographic, biological, psychological, structural, and architectural, to apply for membership. This very broad diversity of inter- ests, along with the opportunities provided for the ex- change of knowledge and points of view, has become one
of the Society's unique and strongest assets. From its be- ginning in 1929, ASA has sought to serve the widespread interests of its members and the acoustics community in all branches of acoustics, both theoretical and applied. ASA publishes the premier journal in the field and annu- ally holds two exciting meetings that bring together col- leagues from around the world.
