The computer may cause information leakage when working. It has become an extremely urgent question studied now. The electromagnetic leakage principle of the computer video signal was analyzed in this paper because the video cable that connects a host to a monitor is thought as a main electromagnetic radiation part on the base of the working principle of a VDU. The information leakage approach, the...
Leaf blight is a common Camellia oleifera disease caused by Pestalotiopsis microspora. The damaged young leaves show blight symptom, resulting in yield reduction. This study was to isolate antagonistic bacteria from Camellia oleifera tissue for control of the leaf blight. Antagonistic bacteria was screened from 175 endophytic bacterias by confront culture method. The results of the study showed that...
3S (Remote Sensing System, Global Position System, and Geographical Information System) provides an entirely new kind of data source for estimating OD matrices. In this paper, we go over our recent works in this field and address the following points: how to pre-process the 3S data collected? How to apply the 3S data for estimating OD matrices without surveys? How to test the results? Finally, the...
In a large scale sensor network for traffic surveillance, the data to be transmitted is huge, which leads to high cost of communication. When sensor nodes are connected wirelessly, the situation will be worse. So it's necessary to reduce the data amount before data packets are transmitted. In this paper, we propose a distributed algorithm base on FCM (fuzzy c-means clustering). Parameters in the algorithm...
The paper applies non-equilibrium statistical mechanics to evaluating the competitiveness of service industry as an evolutionary complex system. And then the evolutionary patterns of eight cities in China are simulated by the SOM. The comprehensive competitiveness of each city is analyzed from the pattern values.
The article introduces the authors'research of an optimum method on the cultivation conditions of a flocculant- producing Strain. Using single factor experiments and orthogonal test, the influence of temperature, PH value and rotational speed on synthesis of microbial flocculants, and optimized culture conditions were studied; 16S gene of the strain was amplified and sequenced.The sequencing was BLAST...
K-means algorithm is one of the most famous unsupervised clustering algorithms. Many theoretical improvements for the performance of original algorithms have been put forward, while almost all of them are based on single instruction single data (SISD) architecture processors (GPUs), which partly ignored the inherent paralleled characteristic of the algorithms. In this paper, a novel single instruction...
Geospatial computing today is highly manual requiring large amounts of human capital. The systems used for processing were designed for stand-alone environments, are inappropriate for modern distributed, heterogeneous network environments as Internet due to their closed architecture, and their lack of interoperability, reusability, and flexibility. The need of an intelligent architecture that can...
