As one of the most popular platforms for processing big data, Hadoop has low costs, convenience, and fast speed. However, it is also a significant target of data leakage attacks, as a growing number of businesses and individuals store and process their private data in it. How to investigate data leakage attacks in Hadoop is an important but long-neglected issue. This article first presents some possible...
A new low-power wrist-worn miniature device used for real-time wireless heart rate (HR) monitoring and fall detection is presented here. This device consists of sensors, signal condition circuits, microcontroller, and system communication module. Power management and algorithms are applied to achieve low power function. Using PASW Statistics 18.0(SPSS Statistics) software to analyze the 54 HR date...
With the rapid development of transportation industry, more and more attention was paid to its management. The construction and development of low-carbon transportation system is so important a task. Based on the existing problems in the transportation system, as well as the actual situation in Xinjiang, the paper proposed an idea of low-carbon in transportation system. It makes full use of ASP (Active...
The objective of load identification is to manage power consumption by the determination of the operation schedule of individual appliances. We applied fuzzy clustering analysis and fuzzy pattern recognition algorithm to load identification in this paper. In the method, the most ideal state is to treat each household appliance as a classification, then cluster them, and get a clustering result about...
Dust generated in coal production brings a great potential hazard to safe production and the health of production workers. According to requirements of the system for water supply, this paper designs a downhole high-pressure dust reduction and water supply system monitor device based on PIC18F4580 singlechip, including realtime monitoring of water tank level of water supply system, water outlet pressure...
Accurately estimating the deformation of rock mass is a very important work for surveyors. Aiming at the limitation of the conventional grey GM (1, 1) model, we propose that the structure methods of background value and the initial condition in grey GM(1, 1) model have an important influence on this model's precision and adaptableility. From this point of view, an optimized grey model is developed...
