Due to the existence of nonlinear, multi-variable coupled of internal mismatch and wind of external disturbances, the Extension control is designed to fulfill the auto-tuning of control parameters for pitch, roll and yaw angle. Building Matlab simulation model to verify the control effect of the Extension controller, and programming GUI monitoring interface on three-dimensional trace and attitude...
Wave buoy has been more widely applied in the ocean measuring field, and the bidirectional communication between the wave buoy and the data center has become a hot area of research. The communication system transmits signal securely and effectively to the upper computer system for our references, and concurrently, accurately executes commands from upper computer system on lower computer system. Based...
It is a great idea to make many normal computers together to get a super computer, and this computer can do a lot of things. This is the concept of cloud computing. Cloud computing is an emerging model of business computing. And it is becoming a development trend. This article compares cloud computing and grid computing. Internet has connected all the computers in the world. Grid computing has been...
As a practical and efficient technique to access XML data, keyword query approaches should address two main problems: enable users to express their query intentions accurately and provide matching algorithms to realize users' query intentions faithfully. Most of the existing researches concentrate on the second problem and the first one is always neglected. In this paper, we propose a novel XML keyword...
With the development of computer network, the Internet culture generated based on Internet interaction has been increasingly paid attention to In the process of Internet cultural transmission, the transmission of Internet symbols is one of the important elements. The Internet world has rapid means of transmission with barrier-free transmission range, and these factors play a crucial role in the rapid...
With the development of parallel computing, distributed computing, grid computing, a new computing model appeared. The concept of computing comes from grid, public computing and SaaS. It is a new method that shares basic framework. The basic principles of cloud computing is to make the computing be assigned in a great number of distributed computers, rather then local computer or remoter server. The...
