Longitudinal minimum safety distance (LMSD) is a key indicator to determinate the probability of longitudinal vehicular collision. A novel LMSD model based on fuzzy reasoning was designed with consideration of driver's intention and driving circumstance. The model simulation was realized in MATLAB/Simulink and the experimental tests were performed under various driver's intentions, weather conditions...
Memory optimization, energy conservation and fault tolerance are the essential research topics in the wireless sensor network (WSN). In this paper, a real-time, memory-efficient, energy-efficient and fault-tolerant WSN system LiveOS is designed and implemented. Compared to the other systems, LiveOS has several typical features. On the one hand, the optimized Rate-Monotonic Scheduling (RMS) mechanism...
In this paper, linear quadratic stochastic zero-sum differential games for discrete-time Markov jump systems are discussed. It is shown that the existence condition of finite horizon stochastic zero-sum games is equivalent to the solvability of the associated difference Riccati equations, and that of infinite horizon stochastic zero-sum games is equivalent to the solvability of the associated algebraic...
Inflammatory responses to lung injuries are mediated through enhanced production of reactive oxygen species (ROS). We describe the use of activatable NIR fluorescent agents with high sensitivity to ROS to image the lung during conditions of high inflammation.
Wireless sensor networks (WSNs) will play a significant role in precision agriculture to support sustainable development. Since it's a more economic and practical solution to deploy reprogrammable sensor nodes than non-reprogrammable ones, sensor node reprogramming technique becomes a key issue. Currently, the challenge of sensor node reprogramming mainly results from the resource constraint and diverse...
Wireless Sensor Network (WSN) is one of the key technologies of 21st century, while it is a very active and challenging research area. It seems that in the next coming year, thanks to 6LoWPAN, these wireless micro-sensors will be embedded in everywhere, because 6LoWPAN enables P2P connection between wireless nodes over IPv6. Nowadays different implementations of 6LoWPAN stacks are available so it...
Nowadays the Ad hoc network and WSN technologies are getting more and more public attentions and their applications increase rapidly and broadly. In this paper we present a mobile wireless network integration platform based on ARM9 and Linux OS which realizes the interconnection between WSN, ad-hoc network and TCP/IP network. The final results show that this platform realizes the expected goals and...
Researches on efficient wireless routing protocols have attracted a lot of attention recently. The classic wireless routing protocols, such as AODV and DSR, are distance-driven and table-driven, which are rarely addressing the energy consumption issue. Therefore, it is necessary to develop a new network protocol that can provide higher energy efficiency and achieve longer network lifetime. Considering...
This paper focuses on the On-Line Transaction Processing (OLTP) performance evaluation methods for high performance fault-tolerant (HPFT) computers. By analyzing transaction features of Bank intermediary business (BIB), we design the BIBmodel, the database model and the transaction/frame model of bank intermediary business, and develop the BIB benchmark (BIBbench) as the performance testing suite...
In ground explosion test, due to the high temperature and pressure as well as the high shock wave current, it is required to be assisted by multiple robots to collect the data and survey the dangerous environment. A method making use of robot sensors to survey the test ground environment data and tracking propagation of shock wave through mobile robots is presented. Besides, an approach of multiple...
The dominant position of High-Performance Fault-Tolerant (HPFT) computers in security and economics has advanced the studies on the performance benchmarks on the HPFT computers in the specific field, such as bank finance and telecommunication etc. Although TPC (Transaction Processing Council) has proposed some benchmarks models for different OLTP (On-Line Transaction Processing) complex business,...
Natural scenic image representation is a very active and promising research domain both in images visual perception, understand, modeling and in image retrieval. A hierarchical organization and representation approach for conceptualized scene images is proposed. Based on scenic image semantic learning, a semantic representation vector for a scenic category is formed so that three level codes hierarchy...
This paper describes a cooperative MANET protocol dedicated to intelligent transportation systems and its new experiment results in mobile scenarios. The protocol is named CIVIC (Communication Inter Veacutehicule Intelligente et Coopeacuterative). It is an auto-configuration inter-vehicle communication protocol, which supports ad-hoc and infrastructure networks, contains reactive and proactive routing...
A multiscale mathematical model was developed to distinguish responses of external and cellular respiration to exercise of moderate intensity. The simulation shows that the characteristic MRTs of external and cellular respiration are similar even when a transit delay exists between the tissue cells and the lungs. The results of our model show that the O2 transport processes from lungs to muscle are...
Cardiac arrhythmia is a class of serious heart diseases that threatens many people. Current arrhythmias diagnostic techniques seem to be partially efficient due to the application limitations either in time or in space. The paper presents a real-time continuous arrhythmias detection system (RECAD) platform based on the wireless sensor network technology. This system provides long-term real-time surveillance...
