The purpose of this paper is to estimate an index that can reflect public emotions towards environmental status based on micro-blog data. We first analyze the micro-blog data by emotion classification and sentiment analysis techniques to obtain people's positive/negative emotional level about their surrounding environmental conditions. Afterwards, the correlation between an emotional index and the...
It's very important to detect the leakage of oil pipeline timely and accurately in order to reduce the losses and ensure the smooth operation of oil pipeline. However, the leakage monitoring of the pipeline is difficult because normally the pipeline is very long and is often buried underground or underwater. Brillouin optical time domain reflectometry (BOTDR), which can distributedly measure the temperature...
The explosive growth of Internet-connected consumer devices in the digital home has made home networks one of the important emerging topics in networking research. A rich body of research efforts have been made to study broadband performance and home network management, little is known about network traffic that are exchanged within home networks or between Internet-connected devices in home networks...
Modern research equipment such as telescopes, particle colliders, and supercomputers is generating so large amounts of data. Consequently, many scientists worry that they will not be able to keep pace with the deluge. The extremely large data volumes have brought great challenge to retrieve the relatively small percentage of records which are essential for further research. The main index technologies...
Wireless sensor networks have been widely suggested to be used in Cyber-Physical Systems for Structural Health Monitoring. However, for nowadays high-rise structures (e.g., the Guangzhou New TV Tower, peaking at 600m above ground), the extensive vertical dimension creates enormous challenges toward sensor data collection, beyond those addressed in state-of-the-art mote-like systems. One example is...
The rapid growth of broadband connections and home networks has created new application opportunities such as video streaming and remote health care. However, managing and securing the increasingly complicated home networks has remained a serious challenge for most home users who have little technical expertise to manage their home networks and connected devices. Towards this end, we will demonstrate...
Recent years have witnessed rapid growth of innovative and disruptive Internet services such as video streaming and peer-to-peer applications. As network traffic of these applications continues to grow, it has become a challenging task to understand their communication patterns and traffic behavior of end hosts engaging in these applications. This paper presents a novel approach based on behavioral...
Scientific workflow system (SWFs) is a tool which is used in scientific research. SWFs is a useful tool that brings remote data access and management under distributed infrastructures to the desktop. Because the Scientific workflow is highly data-centric naturally, it makes the scientific data management, analysis, simulation on distributed infrastructures challenging. When scientist use a SWFs to...
The system is the carrying water intelligent robot based on C8051F410. A C8051F410 MCU is adopted as the main controller to control the motor driver module L293, the motion control module, LCD, automatic water storage module and automatic alarm module. The black and white line are detected through the infrared photoelectric sensor module ST178H. The robot goes forward along the black line and transports...
This paper presents a novel approach for designing the portable wireless ECG monitoring terminal for use in mobile application in a personal healthcare scenario. For portable application purposes, an ultra-low power 16-bit micro controller acts as the core unit of the terminal. The ECG signal measurement module, storage module and Bluetooth wireless communication module are assembled to construct...
Multiple path dissemination is recognized as an important feature to improve the reliability and efficiency of networks. However, most multipath routing proposals focus only on disseminating additional routes to increase the reliability of the Internet, and do not concern the security issues that the additional routes bring to the table. In this paper, we attempt to understand the feasibility of utilizing...
Recently wireless sensor networks have been widely suggested for Structural Health Monitoring. In such applications, diverse sensor nodes are deployed in a building structure, collecting ambient data such as temperature and strain from various locations and reporting them to a central base station for processing and diagnosing. For today's high-rise structures (e.g., the Guangzhou New TV Tower, a...
Because the all factors of interference in R wave of normal ECG signals are few except for respiration, this algorithm uses R peak and position information to extract respiration signals (EDR) {ECG derived respiration signals }. The algorithm firstly get the correct R peak and position information from ECG, then interpolation should be done to keep the sample number the same as the original sample...
The 2D axisymmetric, real gas model was developed to calculate the ejector in the ejector cooling system. The calculation of the real gas model occupies more computer resources, but its result can be more authentic. The CFD model was validated with available experimental data. Predictions at the operating conditions in the ejector cooling system were discussed. The aim of the prediction is to obtain...
Wireless sensor networks (WSNs) have been increasingly deployed for both civil and military applications under harsh, unpredictable or open environments. Such environments create opportunities for the intruders to launch a variety of attacks on multiple protocol layers in WSNs. This paper proposes a behavior monitoring and analysis framework for large scale WSNs. Within this framework, we address...
Intrusion Detection System (IDS) is the key technology to ensure the security of dynamic systems. We employ a sequential pattern mining approach to discover significant system call sequences to prevent malicious attacks. To reduce the computing time of generating meaningful rules, we design a weighted suffix tree structure to detect intrusive events on the fly. The experimental results show our method...

Then it determines the strategy and specific task in the near future and in the long-range view. After that, it designs logistic system and plans function in logistic garden, and designs...
To guarantee the grain’s safe storage, it’s necessary to strictly control the stored-grain’s internal and external influence factors such as temperature, moisture, humidity and pests. The application of information fusion techniques on monitoring and controlling system of stored-grain condition is a useful consideration. In this paper, a new method based on multi-parameter and two stage information...
