Due to the prevalence of Multi-set high-dimensional data in the era of big data, visualization and visual analysis of multiple sets of high-dimensional data are critical to the discovery of data patterns. Parallel Coordinates Plot (PCP) is mainly used for visual analysis of different attributes of the same set. The classic method for visualization on multi-set high-dimensional data is to use a conventional...
The wisdom tourism is the important development direction of tourism which will realize the refinement and personalized of tourism. The wisdom tourism needs support of the data flow processing platform and framework because tourism data is dynamic, large number and multi-dimensions. This paper describes a two-stage modular data flow processing framework based on data view and data service. Taking...
With the rapid development of radio service and monitoring facilities, radio monitoring application steps into big data era. Big data analysis technology can help us get valuable information through dealing with massive monitoring data, which offer guidance to wireless spectrum resource management, abnormal signal detection, etc. In this paper, we adopt association rule mining algorithm to realize...
Monitoring public safety and emergency require equipment that detects the occurrence of emergencies immediately and creates an exact and detailed information about the situation and location of the emergency. Such tools may assist to alleviate desolation under harsh conditions related to natural or human-made disasters by quickly and semi-automatically identifying the type, extent location, intensity,...
The conventional methods of data analytics for flight safety monitoring have met many bottlenecks. This paper analyzes the insufficiencies of the preliminary business process of an airline. For the purpose of meeting requirements of efficiency and accuracy and avoiding the drawbacks encountered before, the architectural framework of the flight safety monitoring platform utilizing big data technology...
The identity authentication system is based on multi-attribute and identity in broadcasting monitoring system. The scheme mainly uses the multi-attribute encryption Attribute-Based Encryption (ABE) as the core, draws Identity-Based Encryption (IBE) to generate the global unified Global Identifier (GID), and proposes the GID-Attribute-Based Encryption (GABE) encoded technology. The method is mainly...
The paper puts forward new ideas for the establishment of distributed price monitoring system on based on the Multi-Agent theory, in order to make the price monitoring process intelligent, the fault diagnosis of real-time price intelligent and conflict resolution intelligent. Price monitoring intelligent system based on Multi-Agent, which realize the intelligent operation, control and supervision...
In this paper, it discussed the process of completing a “Seawater COD Analyzer” engineering prototype based in the On-site Analytical Technology of Chemical Oxygen Demand(COD). The internal structure of the prototype consisits of a photoelectric signal collector, a reaction chamber, an ozone generator, a water sample heating tank, various liquid or air pumps and valve body required by the system,...
