We present StreamMapReduce, a data processing approach that combines ideas from the popular MapReduce paradigm and recent developments in Event Stream Processing. We adopted the simple and scalable programming model of MapReduce and added continuous, low-latency data processing capabilities previously found only in Event Stream Processing systems. This combination leads to a system that is efficient...
The planning and scheduling problem of distributed guidance system (DGS) is investigated. A distributed planning and scheduling approach for DGS is proposed based on negotiation of Multiple Agent System (MAS). A distributed architecture of MAS for DGS is designed, and the functions of agents for different layers are presented elaborately. A contract-net-based coordinate protocol between launching...
This article proposes an agent-based real-time monitoring system for large scale peer-to-peer video streaming platforms which provides traffic, user receiving quality and system information through web-based presentation. The information is useful for helping service providers to assess the system performance as well as the quality of the streaming service. The monitored information is also stored...
Collecting and analyzing real-time data of a distributed wireless sensor network system is very challenging since it combines a series of processes to continuously monitor and respond to a wide variety of events. This paper presents an event-driven, real-time data collection system architecture for an independent living spaces monitoring system. A service-replacement-based timestamp matching structure...
We present a scale-invariant face detection approach based on boosted cascade classifiers using range images as input. The detector was developed to be employed as a preliminary stage for any real-time 3D face recognition system. The required computation time for this task was considerably reduced by eliminating the need for scanning an input image in multiple scales. Our experiments were performed...
The Botnet command and control (C&C) behavior becomes more and more dynamic and rapid so that information security analyst is difficult to capture the Botnet behavior in real time. In this work, we proposed a Botnet C&C behavior tracing system (naming C&C Tracer) for capturing the Botnet C&C behavior. The C&C Tracer consists of three components, such as: C&C active behavior...
In recent years, disastrous earthquake assault the human frequently. The evaluation and estimate of the loss and damage in seismic disaster is an important factor for earthquake emergence and post-earthquake reconstruction decision-making. This paper synthetically designs a set of disaster real-time evaluation system based on the seismic networking of things. This paper firstly collects real-time...
Road transport is one of the most important parts of logistics carry. In order to improve efficiency and quality of logistics carry, It is required that diagnose and maintain remote trouble carry vehicle rapidly. This paper researched the Remote fault Maintenance Support System of Logistics carry Vehicle based on network. Some techniques including embedded computer, wireless communication, network...
Supervisory Control and Data Acquisition(SCADA) systems are deeply ingrained in the fabric of critical infrastructure sectors. These computerized real-time process control systems, over geographically dispersed continuous distribution operations, are increasingly subject to serious damage and disruption by cyber means due to their standardization and connectivity to other networks. However, SCADA...
This paper used middleware technology, using the network as the carrier of information, integrated the three-layers C/S software structure model into the manageable multi-layer software architecture, and used this architecture to construct a communication network real-time monitoring system that has good real-time performance, stability, and scalability.
The existence of wireless technology and the emergence of mobile devices enable a simple yet powerful infrastructure for business application. Some early efforts have been made to utilize both technologies in food ordering system implementations. However, the food ordering systems that have been proposed earlier exhibit limitations, primarily in cost effectiveness, allowing customizations and supporting...
Nowadays, to avoid over-speed and parking violation, repair vehicles are commonly monitored and positioned under monitoring and dispatching system by most of local-level power supply enterprises. With the development of electric utilities, power supply enterprises are urged to improve their response speed to power troubles. In such a situation, electrical repair vehicles must be under a status of...
The thesis introduces the overall structure of the electric power monitoring system. In ord to solve slow speed and poor real-time of the current system, the thesis focuses on designing the real-time database of the power monitoring system and implements the real-time database of SCADA by referencing to the ideas of Hibernate, and then completes the design.
State-of-the-art local feature descriptors like SIFT or SURF require a significant amount of computational power which prevents their usage in applications with real time constraints. Despite recent efforts to simplify the calculation of feature descriptors, a faster computation comes often to the disadvantage of weakening the invariance to rotation or scale. Recently, Tola et al. introduced DAISY,...
At present, the level of heat treating is relatively low. With the development of production technology, how to improve the level of information of heat treating industry is becoming increasingly urgent. Heat treating is an important part of the manufacturing industry. The reliable and real-time data are supported by RFID technology which is an advanced means for data collection and acquisition in...

The project has been in use in water supply system of Xi'an Xianyang International Airport. It indicates by operation that the design project is practical and stable.
Next-generation gaming systems enable users to interact with the consoles without the need to touch a game controller. To achieve a more interesting game for two players, we present an interactive boxing game system using motion sensing and analysis. Our system can be described in twofold: (1) Hardware structure, and (2) Software flowchart, which integrate image and video processing techniques for...
This essay introduces a specific speed timing system used in cycling, which was built by the skill of electrommunication, network communication and database technology. In this system, a wireless real-time timer technique was adopted and communication master station was used. As a result, timing data can be real-time transmitted, stored and analyzed. Owing to the special-used hardware and software,...
Nowadays, it's an age of information. The information technology based on computers is developing rapidly, which provides basis and possibilities for digital learning. Now network environment has developed perfectly, the computer technology foundation is almost mature, and the information resources are very rich. Above these, it is very meaningful to develop a digital learning environment to support...
In this paper, one dynamic configurable channel (DCC) algorithm was proposed to conform the need of realtime and dynamic bus channel allocation of CAN bus. The channel configuration of CAN bus was dynamic changeable at system runtime in this algorithm. A backend channel configuration database(CCD) for dyanamic channel mapping was presented to ensure the requirment of bus allocation at runtime. Bus...
