Urban road congestion is increasingly serious, in order to optimize the traffic situation, and improve the efficiency of vehicles, so as to provide service for traveling user. Then analysis four major systems, namely the bus electronic station board system, evaluation system of urban road traffic state, urban traffic guidance system and website demonstration system. Regarding average travel speed,...
With the rapid growth of graphs in different applications, it is inevitable to leverage existing distributed data processing frameworks in managing large graphs. Although these frameworks ease the developing cost, it is still cumbersome and error-prone for developers to implement complex graph analysis tasks in distributed environments. Additionally, developers have to learn the details of these frameworks...
Based on the J. Tinbergen's improved C-D production function and Solow Growth Model, the co-integration test, Chow breakpoint test and constant return to scale test are introduced to measure the progress of science and technology, and the scientific and effective standardized evaluation method is given. According to the 1995–2010 input-output data from Qingdao city, the empirical results show that...
Semantic issues are highly concerned with high-level interpretation in image understanding, which include text-image gap and its own affinity. Concentrating on text-formatting with entities in images, three sophisticated methodologies are roundly reviewed as generative, discriminative and descriptive grammar on the basis of contextual features. The following objective benchmark for visual words is...
On the base of the assumption that the recycled quantity of used products is affected by the interaction of recycling price and sales volume, this paper researches closed-loop supply chain's pricing and coordination, gives system members' optimal pricing and profits in decentralized decision and centralized decision and finds that reverse supply chain itself is in coordination and traditional forward...
In order to reduce the difficulty of applying ZigBee technology to wireless sensor network system, this paper introduces a serial transparent transmission system based on ZigBee protocol, and gives a method of detecting nodes voltage. Using this method can flexibly grasp the electrical quantities of terminal node power supply equipment in network. This system's core hardware is Chipcon's CC2430, and...
