—Automatic Eating Detection (AED) provides an important tool to help users regulate their dietary behavior for many health applications, such as weight management. In this paper we propose an AED solution using a head-mount and a wrist-worn accelerometers that are commonly available in commercial wearable devices. Experimental results, using Google Glass(More)
In this work we study the feasibility and usability of an assistive food journaling system that sends users just-in-time reminders when unique hand gestures during food consumption are detected using a smartwatch. Our study shows that participants were able to sustain food logging throughout a 2-week period with the help of our eating detection system, as(More)
The single greatest opportunity to improve health and reduce premature death lies in personal behavior. While technology-based behavior intervention has been around for many years, the emerging smartphone and wearable sensing technology brings great promise to push health behavior change further by inferring and predicting real-time behavior occurrence and(More)
Despite the continued technology advances for smartphones, there are still few tools available to end users for understanding the causes of the network problems when encountered. The users often have to rely on the signal bars, which unfortunately is a poor indicator of real network issues that may arise even when the signal is good. In this paper, we(More)

This paper proposes another technique to forecast Chinese mobile user based on the ARIMA model. There are two major premises to use ARIMA model in mobile user prediction: mobile market is mature and still has big space for development. On the basis of the historical incremental mobile user number from 2002q1 to 2009q4, through model identification and(More)
A method of genetic algorithms is briefly introduced in research of handwritten digit recognition in this paper. Considering the features of handwritten digit, genetic algorithm is elaborately designed to cluster the digit samples, so as to implement the handwritten digit recognition. And the experiment shows that genetic algorithm is effective in(More)
In satellite network the nodes are far from the terrestrial station, so the transmission delay between the satellite and the terrestrial station is long, furthermore the nodes mobility is intensive. Based on those characteristics an new network management architecture was build for the satellites network. The method that disposing a local policy decision(More)
