Daniel Arnold, 14 from San Diego, has been working on a new type of model for train tracks. According to his experiment, using the modified spring switch track (which incorporates an extra spring from the existing model already used worldwide today) would prevent train derailments almost entirely.
Vighnesh Shiv, 17 from Portland, Ore., developed a platform that automatically analyzes music and can idenfity the instrument and individual notes. This technology, he says, could also be used for other sounds to extract information. For example, it could be used for healthcare purposes to classify electrocardio analysis.
