BACKGROUND Health is associated with amount of daily physical activity. Recently, the identification of sedentary time as an independent factor, has gained interest. A valid and easy to use activity monitor is needed to objectively investigate the relationship between physical activity, sedentary time and health. We compared validity and reproducibility of physical activity measurement and post...

Current WPSM research is focused on developing a set of wearable, minimally-invasive sensors that monitor and collect raw data on five elements of a warfighter’s physical and mental function: core body temperature, hydration, cognition, injury, and life signs (heart, respiratory, and activity rates). Sensors would also collect data on variables that affect physical and mental function, such as ...

Patients' functional recovery at home following surgery may be evaluated by monitoring their activities of daily living. Existing tools for assessing these activities are labor-intensive to administer and rely heavily on recall. This study describes the use of a wireless ear-worn activity recognition sensor to monitor postoperative activity levels continuously using a Bayesian activity classifi...

In the last years, there has been increasing interest in quantitative features of the specification and analysis of systems. Such quantitative aspects include the consumption of a certain resource or the output of a benefit. Both weighted automata and weighted logics [7] are means to achieve this quantitative description of systems. They can be employed for both finite and infinite input. Very ...
