To satisfy the stringent requirement of ocean monitoring in Marine Intelligent Transportation System, Marine Sensor Networks (MSNs) is envisioned as one of the most effective solutions. In this paper, we study the Heterogeneous and Double Paths MSNs (HDPM) architecture with Sensors (SNs) in view of the reliability of the networks. And we propose a generic integer linear programming (ILP) model to...
An approach using morphological filter technique is proposed to determine the respiratory rhythm from the photoplethysmographic (PPG) signal. As the structuring elements of morphological filter have a decisive effect on the analysis result, in the study the structuring elements are determined by the individual heart rate adaptively. The procedure was tested on a group of healthy subjects. Compared...
The development of modern education technology has promoted the changes of teaching pattern and examination pattern, the appearing of online examination system (OES) is the best embodiment of these reforms, and the monitoring system is designed to ensure the fairness and impartiality of the OES. The paper provides the structure and function of OES and monitoring system, discusses the key problems...
Under the background of the increasingly serious global energy crisis and environmental problems, governments and enterprises around the world have paid more attention to the development of a new generation of sustainable energy. The fuel cell bus has become an ideal choice for new energy vehicles due to its zero emission, high efficiency as well as long endurance. A fuel cell bus consists of various...
In this paper, we propose an intelligent surveillance system which can detect human, recognize certain postures and activities, and send out informing SMS messages when abnormal activities are detected. Nine static postures can be recognized using universal eigenspace technique and projection histogram matching method. After recognizing static postures, Hidden Markov Models are used to recognize human...
