The Internet application faces a world revolution from Web1.0 to Web2.0. The motives which cause this revolution are the internet application already the evolution arrive acculturation stage. The customer of internet has the demand of the characteristic and acculturation. This article on the basis of analysis and research to the Web2.0 related key technology AJAX, RSS, builts a personalized website...
A new template matching algorithm is proposed to improve rotation invariance of mean absolute difference method. The matching function is composed of two sub functions. The first sub-function matches the gray difference between template image and object image, and the second sub-function matches the edge intensity difference between them. The template image and object image are arranged into circle...
In this article, a laser launching and receiving device is designed, it can judge whether a vehicle is ultrahigh or not. This device includes pre-judge system, signal processing circuits, vehicle location determine circuits and warning system. It can determine accurately whether a vehicle running in multi-lane road is ultra-high, and give warning in time, to ensure the safety of vehicles and its crew...
According to the requirement of Multimedia Network and the users' sensitivity for packet drop and delay, the paper puts forward a new protocol IRUDP(Improved Reliable UDP) based on traditional UDP. The paper suggests detecting network congestion according to virtual receiving rate and actual receiving rate and packet drop rate and then responding to it. Simulation results show that IRUDP do not chang...
Personal identity recognition is vital to information society. Multimodal biometric is proved to be a promising authentication technique. The fusion recognition algorithms were studied based on three biometric traits, hand vein, iris and fingerprint. The independent feature extraction and matching modules were designed for each unimodal biometric to output matching scores. The fusion operation was...
Improving the reference [1], give a new scrambling algorithm based on noncom mutative wavelets domain. The statistic characteristic and energy distribution of coefficients was analyzed. The result of experiment shows that we can get better scrambling degree by the algorithm in this paper.
During the process of digital campus construction, there emerged many problems, such as, the rapid rise of the servers in DC (Data Center) and the power consumption, various failure of single point. In order to solve these problems, the author proposes virtual server based on virtual software to improve the efficiency of equipment and reduce the energy consumption and thus reducing operating costs.
In this paper two linear algorithms, the multiple signal classification (MUSIC) algorithm combined with time reversal imaging and the synthetic aperture focussing technique (SAFT), are applied to reconstruct two complicated targets. One target is in an anechoic chamber from experimental microwave data and the other is immersed in water from the experimental elastic wave data. Inversion results from...
A wireless remote monitoring system of water supply based on GPRS had been designed and realized, and it has the advantage of low cost, easy to realize and convenient to maintain, etc. Firstly, the terminal system concentrated the correlative information of sensors by theRS485 line, then through the GPRS and Internet network the relative information of water level, pressure and flux woukl be sent...
Among all categories of modern art, including displaying design, interior and exterior environmental design, packaging design, industrial modeling design and other specialized fields, form construction is the foundation of teaching. This paper gives an in-depth analysis of form construction and its application in practice. Form construction lays a solid foundation for design with its irreplaceable...
The ultrasonic positioning system based on wireless LAN is an important part of real environment digital games. In this paper, based on the battle system of the model tanks, we design a set of indoor ultrasonic positioning system, to achieve the real-time tracking of the model tanks. Through the special design of wireless control technology, the positioning accuracy of the model tanks can reach the...
Traditional PID control algorithm has made an extraordinary contribution for excellent mach inability of NC machine. Along with the increasing of the machining precision and rising of exterior disturbance, traditional PID control algorithm could not meet the needs of requirement for mach inability because of its fixed-parameter. A mathematical model of cutting system was established, and the simulation...
