Monitoring data in coal mine is essentially data stream. With the change of environment, coal mine monitoring data stream implied concept drifts. Coal mine safety evaluation can be seen as concept drifting data stream classification. The method proposed in this paper is based on random decision tree model, and it uses Hoeffding Bounds inequality and information entropy instead of random selection...
Technology for enabling drug delivery with precise control is strongly demanded by patients with diabetes or other chronic diseases. More intelligent functions such as drug loading and delivery in controllable manner without requiring electrical power will make low-cost drug delivery patches come true. One of the promising candidates is triboelectric technology which has been deployed as nanogenerators...
Propeller ventilation is one of the main reasons for the widespread mechanical failures of thrusters, with costly repairs and increased vessel down-time. Most of existing ventilation detection methods have been designed based on the dynamics/control modelling of water and the propeller, and they generally require information or accurate estimates of vessel specific parameters. The main challenges...
Marine operations face the major challenge of increased complexity. Much more data are being collected for diagnostic and monitoring purposes with sensors on board a vessel. However, due to the lack of easy data presentation and interaction, the crew members are overwhelmed by the large volume of information and alert messages, causing serious information overload problems. In this paper, we explore...
Complexity and specificity of monitoring sensor data from marine operations brought a majority of challenges of how to evaluate the visualizations of such sensor data. It's urgently needed to develop and implement new evaluation methods to assess the visualization of maritime data. In this paper, we explore both quantitative and qualitative evaluation approaches to define evaluative metrics of our...
A smart grid is a modernized power grid. Many novel technologies have been used to smart grids. One of the technologies is the wireless sensor network. In this study, a novel backbone communication network is proposed, which combines two different wireless technologies (the ZigBee and Wi-Fi protocol), to form a communication network between the transmission towers in a power grid. The gateway in the...
This research develops a honeybee behavior monitoring system. The proposed system monitors honeybees' daily activities of getting in and coming out their beehive. It provides a new way to observe honeybee behavior and replace the methods of human observation. Specifically, it automatically records environmental parameters near and in the beehive. The information collected by the system is used for...
In Web service composition, operating environment information and user requirement information change constantly. To better adapt these dynamic changes, this paper provides adaptive mechanism of service composition. An adaptive Web service composition framework is presented. The main function modules of this framework including Execution Engine, Monitor, Analyzer and Planner are implemented using...
Network virtualization has been regarded as a core attribute of Future Internet. To improve the quality of virtual network, it is important to diagnose the faulty components quickly and accurately. Recently more and more researches focus on end-user fault diagnosis, which can fit incomplete knowledge and dynamic challenges. In this paper, we present a fault diagnosis system called DiaEO in virtual...
An advanced three-dimensional finite-element S-parameter-simulation tool for microwave tubes is designed. This simulator is based on the second order hierarchical vector finite element method and the proposed combining p-type multigrid and multifrontal block incomplete Cholesky preconditioner. This simulator has shown the high available accuracy and the high-efficiency computational performance for...
Located in the inland arid regions of northwest China, Malian River Basin suffers an intensive conflict of supply and demand of water resources. And it encounters an even worse situation because of its brackish water which affects the utilization of the water. The feasibility of desalination of the brackish water is analyzed and then a new harnessing strategy is proposed, based on a longtime monitoring...
Water vapor is an important kind of greenhouse gas in the atmosphere whose spatial distribution is extremely uneven and time variation is also very fast. It is not only the main driving force of weather and climate change, but also an important formation and evolution reason for disastrous weather, especially meso-small scale disastrous weather. Along with the development of GPS meteorology, people...
• Production line balance is important. — Enhance productivity and reduce cycle time — Get more wafers output • Well-arranged preventive maintenance (PM) is needed — Automatically optimize PM control system for maximum productivity
To study the characteristics of landslide deformation as well as engineering stress state after treatment, establishing reasonable remediation evaluation system, we used inclinometer, the stress meter cable project to establish three-dimensional landslide monitoring system. Through analysed three years monitoring data, we found that different cable force changing with time showed different patterns,...
This paper reports a new microfluidic chip capable of measuring and counting CD3/CD4 T helper cells. A T-cell count was essential for diagnosis of immunodeficiency and lymphocytic diseases. To achieve the measurement and counting of T helper cells, a new microfluidic device comprising a micro incubation and a micro flow cytometer module was presented in this study for sample pretreatment, measuring,...
This paper describes an on-line monitor system based on wireless sensor networks, which could test the ingredients of vehicles' off-gases, and also introduces the design of the hardware and software in details, and transplants the Zigbee protocol on the system at last. With the character of portability and the high precision gas sensors, the system could monitor the off-gases and distinguish the ingredients...
This paper presents the development of a real-time system for monitoring the security of commercial vehicles in road networks. Embedded in the security monitoring system is a commercial vehicle tracking and incident detection algorithm which relies on a combination of vehicle telemetry data obtained from Global Positioning Systems and on-board sensors to continuously monitor the route choice and car-following...
Modern software model checkers are usually used to find safety violations. However, checking liveness properties can offer a more natural and effective way to detect errors, particularly in complex concurrent and distributed e-business systems. Specifying global liveness properties which should always eventually be true proves to be more desirable, but it is hard for existing software model checkers...
To catch up with today's fast changing business markets, web services has never slowed down its paces for evolution. As a consequence, service consumers have to employ in-time upgrades to guarantee continuous business integrity and avoid unnecessary runtime errors in their IT systems. However, a new web service release can involve hundreds of changes, and thus it is non-trivial for the service consumer...
Due to the dynamic nature of virtual organization (VO), it is necessary that multi-agent system aimed to form and operate VO should be robust in cooperating process. We present a model of flexible exception handling facilitated by polices and contracts, in which the flexible evolvement process of exception handling is divided into three phases: exception analysis, plan generation, and plan deployment...
