Martinez Bas	On the Challenges of Longitudinal, Multi-Modal, Ubiquitous Sensing Studies	2022		.txt	text/plain	502	19	47	In this thesis, we present a thorough analysis of the problem of data quality in ubiquitous sensing studies and suggest methods to increase participant compliance. Additionally, we show to what extent heart rate variability from wearables can be a predictor of stress in real life settings.	cache/b2773t97c36.txt	txt/b2773t97c36.txt
