This article studies a paper cutting platform in a comprehensive approach to folk art, folklore, communication, computer and information science focusing on paper-cut in Hebei China. The main content includes: 1) the data collecting and recording of the scattered Chinese folk paper-cut work in Hebei, 2) the digitization, optimization, compression, classification, icon and pattern extraction, vectorization...
To improve the network active defense ability with intelligence defense, prevention, and authentication methods in campus network. the concept of intelligent active defense system is proposed based on web access control and 802.1X admission control, the two technologies have their own disadvantages whatever web technology or 802.1X access control, but if we develop their own advantages of web and...
The disaster information mapping templates developed according to the distribution of the earthquake and the secondary disasters can improve the thematic mapping efficiency. It can also provide accurate disaster information of disaster and affected body quickly. First, Disaster special subject sign database should be designed, including disaster category symbols, loss assessment category symbols,...
Analysis the limitation of existing search engines and the current user's individual needs, base on user profile, take a research on Personalized Meta Search Engine on the method and key technology.
This paper presents a Trojan-detection system model based on behavior analysis. Through the abstract description of the Trojan's behavior, according to certain rules to establish a behavior feature database, and combining the heuristic analyzer to further analysis and judge whether the program is the Trojans, then do the appropriate processing at last. The experiments show this method is effective...
At present, there are a lot of language sources that can be used in natural language process (NLP), which include corpus, dictionaries, databases and so on. However, because of the large number of the language sources and the lack of the national standards, the marks, formats and other aspects are different in these language sources. This forms the gaps in language resources and causes inconvenience...
Lightning location information is the message on lightning received from lightning monitoring net. It contains lightning time, latitude, longitude, intensity, as well as steepness, positioning errors and other critical information. There're some differences in the information caused by the diversity of lightning positioning system models. This paper introduces a kind of methods on extracting the lightning...
This paper is based on the software product for DengFeng city cement plant and DengFeng ZhongLian cement Limited company. This software system consists of server-side software, client-side software and handheld programmer software. Key technologies used in system contain non-contact IC card and car license recognition etc. The paper elaborated system requirements. Software functions and software implement...
In this paper, "RS", "GIS" and "GPS" are integrated as the "3S" technology, which is widely applied to the construction of the dynamic monitoring system of soil erosion. This system is used to monitor the soil erosion in watershed and pre-warn possible problems hidden in the process of land cultivation, so that measures can be taken to prevent or solve such...
Nowadays natural disasters especial earthquakes frequently occur all over the world. Thus rapid mapping of remote sensing system has practical significance. In this paper, based on the methods of disastrous expression of multi-scale geographic maps and remote sensing images, processes of fast mapping were proposed and researched. It includes quick match of base map database and disastrous thematic...
With the development of digital technology, while digital publishing provide convenience for people to access to information it also influences the management mode of traditional copyrights and challenges current copyrights system. In this context, how to protect digital copyrights and promote the healthy development of digital publishing industry through the creation, management, protection and application...
In this paper, a new topology discovery algorithm is proposed for Mobile Ad Hoc network and its application is developed on Linux system. With a mixing usage of mobile agents and data collection, the algorithm aims to solve the topology discovery issue in hierarchical Ad Hoc network scenarios instead of flat ones. The algorithm is implemented under Linux system and the test result shows that our algorithm...
It is generally a few hundred to several thousand kilometers of long distance oil pipeline, and modern oil pipeline often adopt the close-line oil transportation, so the whole pipeline is a unified set of hydraulic system. Once the disturbance occurs in somewhere along the line, which will sweep the whole line, and propagation velocity is much faster than manual response capability making a high demand...
Begin with the application requirement of parking guidance system, the paper analyzes the causes of parking problem in big cities and put forwards the basic ideas about parking guidance. The major contents of the parking guidance system including the preparation for system basic data, on-site management of parking spaces, dynamic prediction about the change in parking capacity, route selection, graded...
Tile caching technology can significantly improve the efficiency of WebGIS systems. However, the current tile caching only works well on data that is never or seldom updated. Hence, traditional tile caching could not be applied to editable WebGIS. This paper proposes a dynamic tile caching method (D-TileCaching), by which tile caches can be updated in real time and thus are applicable for editable...
Based on the Qt application framework, using the object-oriented technology, the GIS map projection transformation system which can be used cross-platform and independently is designed and implemented by programming. Referred to the specifications of map projection transformation that OpenGIS Association released, inverse transform method which is suit to be realized by programming is adopted, common...
Take the relational database as the data model, in analyzes several kinds already in the data encryption technology base which has, studies the database data to save and to establish the corresponding database confirmation mechanism by the scrambled text way. Proposes based on the connection sub-key production algorithm as well as based on the user information key management technology and the field...
Recently, data de-duplication, the hot emerging technology, has received a broad attention from both academia and industry. Some researches focus on the approach by which to reduce more redundant data. And the others investigate how to do de-duplication at high speed. In this paper, we aim at reducing the time and space requirement for data de-duplication. We describe a clustering architecture with...
