Underwater Pipeline Oil Spill Detection Based on Structure of Root and Branch Cells

Journal of Marine Science and Engineering (2020)

Huajun Song Jie Song Peng Ren

The existing oil spill detection methods mainly rely on physical sensors or numerical models cannot locate the spill position accurately and in time. To solve this problem, combining with underwater image processing technology, an unsupervised detection algorithm for oil spill in underwater pipelines is proposed for the first time. First, the oil spill region to be detected is regarded as the moving target, and the foreground detection algorithm is applied to the processed images. Then, the HSV (Hue, Saturation, Value) color space of the image is used to screen the oil spill region meeting the threshold requirements. Next, the bitwise of foreground mask and HSV mask into cells are divided. Finally, according to the characteristics of the oil spill image, false detection is eliminated by classifying cells three times. After qualitative and quantitative analysis, it is proved that the proposed algorithm can detect oil spill region accurately.

Intraluminal bubble dynamics induced by lithotripsy shock wave

Journal of Physics D Applied Physics (2016)

Jie Song Jiaming Bai Yufeng Zhou

Extracorporeal shock wave lithotripsy (ESWL) has been the first option in the treatment of calculi in the upper urinary tract since its introduction. ESWL-induced renal injury is also found after treatment and is assumed to associate with intraluminal bubble dynamics. To further understand the interaction of bubble expansion and collapse with the vessel wall, the finite element method (FEM) was used to simulate intraluminal bubble dynamics and calculate the distribution of stress in the vessel wall and surrounding soft tissue during cavitation. The effects of peak pressure, vessel size, and stiffness of soft tissue were investigated. Significant dilation on the vessel wall occurs after contacting with rapid and large bubble expansion, and then vessel deformation propagates in the axial direction. During bubble collapse, large shear stress is found to be applied to the vessel wall at a clinical lithotripter setting (i.e. 40 MPa peak pressure), which may be the mechanism of ESWL-induced vessel rupture. The decrease of vessel size and viscosity of soft tissue would enhance vessel deformation and, consequently, increase the generated shear stress and normal stresses. Meanwhile, a significantly asymmetric bubble boundary is also found due to faster axial bubble expansion and shrinkage than in radial direction, and deformation of the vessel wall may result in the formation of microjets in the axial direction. Therefore, this numerical work would illustrate the mechanism of ESWL-induced tissue injury in order to develop appropriate counteractive strategies for reduced adverse effects.

A review of the current status of small-scale seawater reverse osmosis desalination

Water International (2017)

Jie Song Tian Li Lucía Wright-Contreras Adrian Wing‐Keung Law

The current status of small-scale desalination (produced water capacity 100 m3/day or less) is reviewed to provide an overview of the market segment. The use of energy-recovery devices in this market segment is also reviewed. We find that the Middle East accounts for the largest market share worldwide at present, and reverse osmosis is overwhelmingly dominant among the desalination technologies adopted. Implementation of energy-recovery devices at small scale is rare, which leads to relatively high energy consumption for small-scale seawater reverse osmosis desalination systems.

An Experimental and Engineering Application of an Active Snow-Melting System for Highways Based on Heat-Pipe Technology

Journal of Physics Conference Series (2020)

Jie Song Yufeng Bi Shang Liu Guoqiang Zhong Chao Wang

Abstract Major traffic accidents caused by snow cover and ice on pavements are responsible for large numbers of casualties and extensive property losses each year around the globe. A full-scale heat-pipe-based active snow-melting test system for outdoor asphalt roads was constructed to study and analyze its working performance on in-service asphalt highways. Based on long-term monitoring data, the active snow-melting system was analyzed to determine the temperature-field distribution pattern and relevant influencing factors as well as its performance on asphalt pavements. The research results show that: (1) the system exhibited excellent performance. Three natural snowfall events occurred on the full-scale test platform. In each event, the snow-melting system was able to effectively melt the snow. (2) Under long-term low-temperature conditions in winter, the active snow-melting system was able to increase the pavement temperature by approximately 10 °C. (3) In winter, the underground soil temperature decreased by approximately 4 °C as a result of heat extraction by the underground heat pipes and gradually recovered to its previous level as the outdoor ambient temperature gradually increased. This finding suggests that underground soil can provide heat to the snow-melting system for an extended period of time and continuously ensure its pavement snow-melting performance. The engineering application on the G18 Highway further demonstrates the effectiveness and reliability of active snow-melting systems based on heat-pipe technology.

<title>Multiservice control framework based on pricing and charging</title>

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2001)

Jie Song Bu‐Sung Lee

Providing predictable and stable Quality of Service (QoS) to the network end users is one of the goals of the next generation Internet. To solve different problems related to QoS, the Internet pricing has been researched. This paper proposed a multi-service control framework based on pricing and charging technologies. It consists of three fundamental blocks: intelligent agent (IA), pricing broker (PB) and local pricing agent (LPA). The intelligent agent provides the TCP-like pricing based traffic control at the end users. The local pricing agent is used to implement hybrid-pricing algorithm to make the service price as an indicator of the network status. At the network edge node, it also contains traffic classification mechanisms to provide service differentiation. But the pricing broker controls the policies. It is also responsible to maintain and exchange the price information for the end users and neighbor domains. A simulation has been done in a simple prototype with the hybrid-pricing algorithm and the price based classification. Simulation results show that it can provide service differentiation and maintain the service quality as well. Therefore, the proposed framework provides a simple, flexible way to support multi-service control and improve QoS over the networks via pricing technology.
