Tsunami Early Warning, Yao Li Aug 2021

Tsunami Early Warning, Yao Li

Undergraduate Student Research Internships Conference

This study uses both the traditional attributes, which are earthquake magnitude and location and pluses the tsunami height collected by detecting stations to estimate the height of a tsunami on the coast. The resulting accuracy indicates the tsunami height data collected by the off-shore stations could be used to estimate reliable and robust tsunami source models for tsunami warning purposes.

A Transformer-Based Classification System For Volcanic Seismic Signals, Cristian Bravo Roman, Cindy Mora Stock, Alexander James Hemming

Undergraduate Student Research Internships Conference

Volcanic seismic signals are a key element in volcano monitoring to assess the state of unrest and a possible eruption style and timing. Different sources such as brittle fracture (volcano-tectonic - VT) or fluid movement (long period - LP) generate signals with distinct characteristics in frequency content and shape, but site effects such as attenuation or background noise make their determination difficult to the untrained eye. In cases of unrest or an eminent eruption, the amount of data would require a fast and reliable source of pre-classification to classify and catalogue to aid in the job usually done by a …


Monitoring At-Home Care Patients Through A Scalar Polar Plot Visualization Of Motion Sensor Data, Michael Mcgavin Aug 2021

Monitoring At-Home Care Patients Through A Scalar Polar Plot Visualization Of Motion Sensor Data, Michael Mcgavin

Undergraduate Student Research Internships Conference

In Canada, approximately 18 percent (6.6 million) of the total population are age 65 or older, and 88 percent of people over age 65 want to stay in their residence for as long as possible. This older demographic is a group that is dependent on proactive and preventative healthcare. Using motion sensor data collected from a local company providing home-care services to this demographic, a data visualization was constructed to assist users in observing patient behavior and improving their quality of life while maintaining their independence. However, since the collected data is time-based, it results in a dataset that is …
