The idea of decomposition is becoming increasingly successful and popular in evolutionary multi-objective optimization. An efficient cone decomposition approach was further developed in the conical area evolutionary algorithm (CAEA). This approach improves the runtime efficiency and population diversity of decomposition-based algorithms effectively for bi-objective optimization in practice. In this...
Realization of automatically extracting the role relation from massive unstructured data facilitates the deep semantics of mining big data. Nowadays, methods for network construction are mainly either based on structured data, or based on a single view. Therefore social network construction of role relation in unstructured data based on multi-view is still a challenge. In this paper, a method is proposed...
With the popularity of the Internet, online news media are pouring numerous of news reports into the Internet every day. People get lost in the information explosion. Although the existing methods are able to extract news reports according to key words, and aggregate news reports into stories or events, they just list the related reports or events in order. Moreover, they are unable to provide the...
This paper proposes a dynamic channel utilization method to minimize transmission delay by considering radio interference and wireless link rate for software defined multi-channel wireless mesh networks (SD-WMN). The OpenFlow technology, which enables us to control flows by programming, is employed to effectively utilize multiple channels in SD-WMN for traffic balancing. Existing methods assume fixed...
Community question answering(CQA) websites such as Quora and StackOverflow provide a new way of asking and answering questions which are not well served by general web search engines. With the huge volume and ever-increasing number of users and questions, effective strategies of ranking experts for different questions need to be proposed. In this paper, we first make some analysis on the network structure...
The majority of real-world networks are directed, weighted and dynamic. Aiming at the problem of node role analysis in directed weighted network, in this paper, we introduce topological potential to network analysis and propose a novel node role analysis method based on directed topological potential, which can divide nodes into four kinds of roles based on their behavior pattern and local influence...
With the development of ARM (Advanced RISC Machines) microprocessor embedded system, a method of graphical programming software development is more and more important. The system consists of PC graphical programming software, USB program transmitter and ARM development platform. It is mainly used for developing of graphic software. It can program conveniently through the graphical way, and can perform...
In this paper, an automatic measurement system of leaky Lamb waves dispersion curves based on Lab VIEW is developed. In this system, the PVDF line-focus transducer is controlled to defocus through the movement of the linear stage, and the NI PXI-5154 digitizer is controlled to acquire echo signals, then the calculation program is called to process the echo signals for calculating phase velocities...
SaaS(Software as a Service) has recently made a great impact on the software industry and changed the traditional lifetime of software. To obtain the benefit of SaaS, more and more software products have been converted into SaaS model, including business workflow management systems (BWfMS). Compared with the traditional BWfMSs, SaaS oriented BWfMSs introduce a new set of features which demand a new...
The reforms of the agricultural irrigation management become the important content of the construction of the conservation-minded society and new socialist countryside, however, the traditional management of client/server mode can't meet the requirements. Consequently, the optimization of the irrigation management is inevitable according to the development of the irrigation facilities and the complication...
With the system functions growing rich and the design growing difficulty, using ECU in-loop simulation as development platform of entire system can test the rationality and reliability of the control system design step by step in advance. Thus it greatly enhances the development quality of control system, reduces risk and increases the success rate of the design. Engine ECU hardware in-loop simulation...
Virtual Home Library (VHL) is an integrated IT system that utilizes virtual reality technology and an IPTV set-top box (STB) to virtually construct a 'library' and the relevant reading environment on televisions in people's home. Unlike the online e-book reading applications, Virtual Home Library system can be applied on televisions - the world's most convenient and most efficient communication tool...
Ultrasonic system was developed for detecting channel defects embedded in bonded 2-sheet flexible packages film. This hardware system consisted of spherically focused 22.66-MHz ultrasonic transducer, four-axis precision positioning system, NI PXI-bus embedded controller and ultrasonic pulser-receiver. The software system was designed based on the modularization, realized the echo signal on-line processing...
