Compared to related traditional majors, the Internet of Things engineering major has greater integration and its own characteristics especially the extension characteristic. As for the industry hierarchy for Internet of Things, standardizations are still lacking for its layers. Hence, e-learning on Internet of Things engineering major is challenging with the development of related technologies. This...
Anonymization of the medical document provides effective protection of patient privacy so as to promote the development of anonymization of electronic medical records in China. However, traditional methods which identify patient privacy manually are not only inefficient with frequent errors and omissions but also labor-consuming. To solve this problem, this paper introduces an algorithm which has...
In recent researches, wind speed model of single wind farm has been used to study the traditional wind farms modeling, ignoring the correlation between series of multiple wind speeds. Based on Copula function and ARMA model, a dependent model for multivariate wind speed series is proposed. Firstly, Copula multivariate distribution model is used to capture spatial dependencies, and then ARMA model...
The modernization process of Global Navigation Satellite System(GNSS) is based on Binary Offset Carrier (BOC) modulation. BOC signals have a better multipath mitigation performance than the legacy BPSK signals. Even though, the position accuracy of GNSS based on BOC signals could not satisfy the requirements of high-precision positioning when multipath signal exists. In this paper, we propose a novel...
540 female were measured by using photo and manual measuring methods. Among these people there are 317 young and 223 elder. By using the Matlab program, female's frontal and sided pictures were extracted and the outlines were got, from which the relevant height, thickness and width values could be drawn. Then construct the fitted equation of circumference by linear regression equation in two unknowns,...
With rapid development of computer networks, users need a new solution for network security management, aiming at integration. This paper focuses on context-aware alert analysis, which is one of its key functionalities. A practical and efficient approach to guarantee unified representation of context information, background knowledge and attack knowledge for security alerts is still lacking these...
One common and traditional method of detecting stored-grain deterioration is by measuring grain temperature. The key to stored-grain temperature measurement by acoustic method is acoustic travel-time measurement. In this paper, a phase transform generalized cross correlation with wavelet transform (WT-PHAT-GCC) method for acoustic travel-time measurement is proposed. An experimental system of acoustic...
In this paper, for the problem of spatial correlation and frequency correlation of targets echoes in receiving channels of diversity MIMO radar, based on two-dimensional scatter model in polar coordination system, correlation coefficient and independent condition of radar target echoes in spatial and frequency diversity receiving channels are developed, indicating that for round shaped scatter model...
These days, IDS has been widely deployed and is beginning to gain acceptance as a worthwhile investment. However, at least three disadvantages, which are very high alert rate, fairly high false positives and quite limited ability for detecting distributed and collaborative attacks, hinder its further development. In order to overcome these weaknesses and resolve the conflict with current network security...
