Software-Defined Networking (SDN) opens the configuring interfaces for the data plane to improve its flexibility[1]. In the data plane, the switches are partitioned into multiple domains. Each domain is dynamically configured by its controller. The domains are physically connected via the border switches. In the control plane, each controller supports multiple services. Each service runs the same...
Software industry as a soul and core of the information industry plays a vital role in the development of the world economy. China's present judicial situation of protection of intellectual property rights to software did not achieve the desired effect and piracy of software is prevalent. New Regulations on Computer Software Protection has narrowed the scope of fair use of original “Regulations” to...
This paper proposes an integrated approach to the VNE problem, in which different virtual nodes of a virtual network could be assigned to a physical node as long as this node's available resources can satisfy the total resource requirements of these virtual nodes. We carry out extensive simulations to investigate the benefits of sharing physical nodes. The simulation results demonstrate that (1) Compared...
Hyperspectral imagery contains hundreds of spectral bands, which generates a rather large amount of data, so band selection is often adopted for hyperspectral image analysis. This paper presents a novel approach for unsupervised band selection by transforming the hyperspectral data into complex networks and analyzing the corresponding topological characteristics. The networks' statistical properties...
Use optimized indigenous microbial flora biotechnology to conduct repair experimental research on oil contaminated groundwater in loess area of north Shaanxi. The selected optimized flora include Pseudomonas, Micrococcus, Actinomayces, Penicillium, Aspergillus. During experiment process, add 1.5%'s optimized flora preparation into the polluted waters with oil content of 182.0mg/862.5mg/1 and 1695...
Meteorology is one of the main application areas of high performance computing (HPC) technologies, it is impossible for efficient and accurate weather forecasting and meteorological services without the support of HPC resources. As a kind of networked HPC application environment, meteorological computational Grid makes an integration of diverse computing resources using the Grid technology, providing...
In this short paper, we present a preliminary design of a behavior profiling system in wireless home network (WHN) for network security monitoring. Figure 1 illustrates a schematic architecture of the behavior profiling system that is deployed in a typical wireless home network. The goals of the proposed behavior profiling system are to i) actively learn the traffic patterns of wireless home networks,...
With airlines as background and combining design theory and framework of data warehouse, this paper points out the design and realization process of airlines revenue management decision support system based on data warehouse, and also probe into data acquisition, ETL design, logic model, realization methods and technologies of data warehouse.
Recently, more and more Chinese students begin to learn Japanese as their second language, for the close connections between Japanese and their mother language. However, it turns out that Chinese students feel difficult to learn Japanese, especially Katakana words. They have to listen to the words repeatedly, and it is hard for them to recognize their special sounds and to distinguish the length of...
To manage the knowledge of product development period efficiently, a PDM-based product design knowledge management model was proposed. According to the different characters of tacit knowledge and explicit knowledge, a design knowledge classification and related-representation method were introduced. The integration model between PDM and product design knowledge flow which is the key part of the design...
The data security is one of the biggest problems which inhibit the further application of the ASP platform. This paper put forward an ASP-based security system strategy which includes infrastructure security, safeguard security boundary and computing environment protection. An ASP-oriented intrusion detection model was also proposed, and the intrusion detection subsystem function was analyzed in detail...
Artificial intelligence (AI) techniques have played increasingly important role in antivirus detection. At present, some principal artificial intelligence techniques applied in antivirus detection are proposed, including heuristic technique, data mining, agent technique, artificial immune, and artificial neural network. It believes that it will improve the performance of antivirus detection systems,...
In many multimedia SOC (System on Chip), application software and data are stored either in on-chip memory or in Cache for efficient execution. Therefore, large amounts of on-chip memory increase the area and power dissipation of the whole chip. In order to reduce memory size and its power dissipation, parts of programs and data are stored in off-chip memory, and are loaded into on-chip memory while...
