SQL attack prevention measures are a hotspot of network security research in recent years. In this paper, the principle and characteristics was introduced firstly, then SQL attacks and preventive measures were given. After the concept of prevention model structure and model built, the prevention work process of the model was summarized.

As a special type of mobile ad hoc networks (MANETs), vehicular ad hoc networks (VANETs) are expected to support vehicle to vehicle communication and vehicle to infrastructure communication. The conventional relay selection scheme proposed for MANETs may perform poorly in VANETs due to the unique characteristics of VANETs, including highly dynamic network topology, unstable link status and multiple...
An investigation of joint source channel decoding (JSCD) methods using BPSK modulation applied to a vector quantization of compressed sub band coded source in Communication Network is presented. The proposed decoding scheme designed a feedback algorithm using error-detected source information to improve the error correction capability of the Turbo Log-MAP decoder without changing its constituent decoder...
In order to improve the traditional injection technology and equipment, the totally electrical screw-rotated injection equipment and method are proposed. This paper points out structure of this new equipment, working principle, and key problems need to be solved when using screw-rotated injection. This new equipment makes several breakthroughs and expands the application space for injection technology.
Culture medium's entrying and sterilizing process has the characteristics of nonlinearity, long time lag, big inertia, with lots of influencing factors and control complexity. So it is very difficult for the conventional PID controller to control the process. In most ferment factories, the process was controlled manually. It has the disadvantages of high labor intensity and low accuracy of temperature...
