In-field Calibration of Low-Cost Sensors through XGBoost Aggregate Sensor Data
Kevin Yin, Julia Gersey, Pei Zhang
Effective large-scale air quality monitoring necessitates distributed sensing due to the pervasive and harmful nature of particulate matter (PM), particularly in urban environments…
ZV-Sim: Probabilistic Simulation Framework for Pre-emergent Novel Zoonose Tracking
Joseph Maffetone, Julia Gersey, Pei Zhang
ZV-Sim is an open-source, modular Python framework for probabilistic simulation and analysis of pre-emergent novel zoonotic diseases using pervasive sensing data. It incorporates c…
Preliminary Characterization of Bio-inspired Dog-Nose Sampler for Aerosol Detection
Yahya Naveed, Julia Gersey, Pei Zhang
Before aerosols can be sensed, sampling technologies must capture the particulate matter of interest. To that end, for systems deployed in open environments where the location of t…
Survey of City-Wide Homelessness Detection Through Environmental Sensing
Julia Gersey, Rose Allegrette, Joshua Lian +2
The growing homelessness crisis in the U.S. presents complex social, economic, and public health challenges, straining shelters, healthcare, and social services while limiting effe…
WeVibe: Weight Change Estimation Through Audio-Induced Shelf Vibrations In Autonomous Stores
Jiale Zhang, Yuyan Wu, Jesse R Codling +5
Weight change estimation is crucial in various applications, particularly for detecting pick-up and put-back actions when people interact with the shelf while shopping in autonomou…
