Long-term monitoring of electrocardiogram (ECG) requires a portable inspection system that can offer both high energy efficiency and good signal quality. To manage challenges caused by this requirement, this brief presents an ASIC design for both ECG recording and R-peak detection. By supporting data compression and using a dual-ping-pong-memory architecture, this design leads to a large reduction...
Software security has drawn much attention recently. As an effective approach to detect software vulnerabilities and improve software security, dynamic taint analysis has been frequently researched in the last few years. In this paper, we implement a dynamic taint tracking system LTTS. In order to address the efficiency problem which exists in many of the current taint tracking systems, we also propose...
In order to overcome the defect of physic-chemical monitoring system and enhance the intelligence of biological monitoring technology, an online monitoring system of fish behavior is proposed in this paper. The main contributions of this system are as follows: 1) adaptive background updating algorithm (ABU); 2) automatic camshift tracking algorithm (ACT) with twice searching; 3) particle filter tracking...
The study of a landside site involves many aspects of data collection and data analysis activities. Among the data to be collected are the site location, the landside orientation, the soil profile, and the vegetation cover. Although these data (such as the topography and the distribution of trees) are 3-dimensional in nature, they are usually collected and examined in a 2-D fashion to simplify the...
