Against the problems existing in the collective running projects, such as not-reasonable-enough monitoring means, not-scientific-enough assessment tools, and so on, an overseeing and evaluating system of running training was designed and implemented based on the radio frequency identification(RFID), which has the advantages of high precision, comprehensive and real-time positioning. The system provides...
Cloud computing is one of the most popular Internet concepts, and many large companies provide cloud services to users. These large companies have built their own data centers to support upper layers of cloud services. To save cost and increase flexibility, SDN and virtualization technologies are widely used in data centers. Open vSwitch is an open source virtual switch that supports the OpenFlow...
Until now intelligent video analysis comprises a set of hardware, software and theoretical foundation, all intertwined for targets identification, location, tracking and even behavior forecasting from a scene with almost no human intervention, so as to facilitate people's daily management and resolve exceptional situations in good time. The moving objects detection is a fundamental process in an intelligent...
In access-network-chip testing and verification, problems occur mostly on I2C control interface because of its complicated protocol and high requirement on reliability, using an automated testing tool with simple operation and high testing coverage could ensure the quality of chip as well as shorten the chip development cycle. The paper designs an automated system based on 5SGXEA7N2F45C2 FPGA chip...
seL4 is formally verified for its functional correctness and its kernel modules provide strong support to achieve interprocess communication mechanism. In recent years, some scholars designed Interprocess Communication Systems with library-based architecture. This design abandons Message-Passing technique that most of microkernels adhere to. The present research still insists on the Message-Passing...
The reliability of conditional probability systems refers to the fact that a system operates properly in timeframe [0, t1] provided that it was healthy at the beginning of the timeframe. Enhancing the reliability of the operations of computer systems is possible by implementing fault tolerability. Fault tolerability in a digital system can be obtained through redundancy in hardware, software, information,...
The Internet of Things (IoT) technology, based on the wireless sensor network, is developing rapidly and permeating into agriculture including livestock farming. Our research focuses on the problem that current industrial IoT system for livestock farming is tightly coupled, hard to expand, and with poor network performance. In this paper we proposed an integrated framework of smart livestock farming...
For the widely existing document and relation mixed-type data, this paper proposes a system of storage and query for associated mixed-type data based on the distributed middleware. It adopts distributed middleware as technological tools to integrate databases of different types, which achieves adaptive and efficient data storage performance for document and relation type data. Furthermore, the hybrid...
