Accurate and online Energy Expenditure Estimation (EEE) utilizing small wearable sensors is a difficult task with most existing schemes. In this work, we focus on accurate EEE for tracking ambulatory activities of a common smartphone user. We used existing smartphone sensors (accelerometer and barometer sensor), sampled at low frequency, to accurately detect EEE. Using Artificial Neural Network...
This paper introduces experiences with mobile positIOning data in the web-based tourism management and monitoring system: "Positium Barometer". The system has been developed for tourism enterprises, public authorities, scientists and planners to obtain statistical overviews and standardized analyses about the space-time movement of tourists. Positium Barometer uses passive mobile positioning da...
Presented here is a gravimetric me thod to calibr a te barometers. The difference in forces exerted on th e pan of a balance is observed for tw o we ll charac terized artifac ts of nearly equ al masses but different volumes. During the weighing, air tempera ture and re lative humidity ar e meas ured; the ambient pressur e is then calculated from an a ir density equation. A barometer correc tion...
