SSL VPN system depends on TUN device on Linux host. Without TUN device, it can't be deployed on Linux hosts. In order to overcome this limitation, a new kind of SSL VPN system is developed. This system is based on simulated virtual NIC based on loopback interface. With the help of simulated virtual NIC, SSL VPN client can be deployed on Linux hosts without TUN devices. Thus a Linux host without TUN...
Cross equalization is the core step of time-lapse seismic data processing, it can effectively eliminate the influence which is due to the inconsistent of acquisition, data processing and tube processing parameter. As the amount of data and processing of time-lapse seismic data increasing, it becomes the inevitable trend for seismic data to array on massively parallel processes. It deal with the time-lapse...
Sentiment classification is a way to analyze the subjective information in the text and then mine the opinion. We focus on the sentence-level sentiment classification. On the systematically analyzing the importance and difficulties of the sentence-level sentiment classification, this paper proposes a syntax tree pruning and tree kernel-based approach to sentiment classification. In our method, the...
Support vector machine (SVM) is discussed to use for recognizing cucumber leaf diseases in this paper. Considering that it is a small number of samples, a new experimental program has been proposed which takes each spot of leaves as a sample instead of taking each leaf as a sample. In the experiments Radial Basis Function (RBF), polynomial and Sigmoid kernel function were also used to carry out comparative...
Based on radial basis function (RBF) kernel, a new self-adaptive method to optimize the least squares support vector machines (LS-SVM) parameters, the width of kernel parameter sigma and the LS-SVM regularization parameter gamma are proposed. Detailed methodology steps of this algorithm method are presented. Compared with back propagation neural networks (BPNN), various simulation experiments for...
In order to make the operating system in education easier to understand and practice, we advise to introduce a kind of nanokernel to the beginner because the concept of nanokernel was to reduce the kernel to basic schedular, interrupt and timer, and let others reside in user space in forms of normal processes. XtratuM as a special nanokernel is a part of OCERA(Open Components for Embedded Real-time...
The paper introduces a method of Embedded Wireless Video monitoring System based on GPRS (General Packet Radio Service). First the S3C2410 platform is given based on the Embedded Linux, and the develop software environment on the platform. And then describe how to achieve the image collection on the platform, introduce the program of video capture, accomplish the JPEG (Joint Photographic Experts Group)...
