Earing is often undesirable in the production of deep drawn containers because it results in a nonuniform cup height. A finite element model for earring analysis is developed considering only the flange area of the sheet. It was found that the draw-in depth of the flange increases with the increase of the r value, and it remains invariable when r value is larger than 2. With the increase of the r value, the max thickness decreases and the min thickness increases. If △r>0, four earings are formed. If △r =0, the material characteristics in all the planar directions are same. The flange uniformly flows into the die cavity, no earing is formed. If △r<0, four earings are formed. The earing distribution is dominated by r0, r45 and r90. Both r and △r have much effect on the earing distribution. © (2011) Trans Tech Publications.

Driving System, which is programmed by C#, is a car driving manipulation to simulate the real car driving movement, obtain sense of simulation system. Obviously, Driving System has a lot of advantages as a driving system for fatigue detecting monitor. In driving system, there are three parts, which are the driving Environment, Data acquisition and Data analysis. Driving System can fulfill the interactivity and real time effectively, and has been used successfully in the drowsiness of driving, which can be familiarly analyzed with arithmetic of EEG. © (2011) Trans Tech Publications, Switzerland.

Brain control the behavior of human, When someone thinks of something, there is thinking movements in someone's brain. Collecting the brain electric wave through Neroscan, Inspecting the feature of the C3,CZ,C4 of Brain electric wave, which apply for the Com Component and analyze the Com principle deeply. Adhibition of control signal to control the virtue of the movement of tractor, At last, Computing the exactitude of control of brain electric wave, The result of experiment is perfect. © (2011) Trans Tech Publications.

In the information era, information security becomes more important, the use of EEG as identification tool become more and more. In this paper, we used the subjects' photos as stimulation. In order to obtain the Identification classifier of different subjects, we used AR model to convert the EEG signals from time domain into the frequency domain, used Fisher' distance to extract the feature. Finally, we calculated the feature by using BP neural network. Through the analysis of the correct recognition rate, error recognition rate and false recognition rate, we achieved the purpose of using EEG as identification tool.

What happens when a firm does not want to be vertically integrated? Within a buyer-supplier relationship, and in a context of specific investments, we analyze firm interactions when they decide to cooperate instead of becoming vertically integrated. We develop two systems to monitor the way that presents an alternative to vertical integration with firms that cooperate with each other under incomplete contracts. The contribution of our approach is twofold: first, a mathematical component, where single game is monitor the man to computer, and the double theory is monitor the man to man to deciding, and at last we implement them with C# technology and the result is recorded in EEG system. ©2010 IEEE.

This paper focuses on the person authentication problem based on EEG signals. Many features extracted from EEG recordings have proved to be unique enough between subjects for biometric application. However, different features show different discriminative power for different subjects. Here an authentication system was presented, which makes use of feature combination architecture. The results demonstrate to improve the system performance. Depending on the security level, different thresholds can be applied. The influence of different thresholds on system performance is discussed. © 2010 IEEE.

Hibernate is a object relational mapping framework of open source code, which conducts light-weighted object encapsulation of JDBC to let Java programmers use the concept of object-oriented programming to manipulate database at will. The appearence of the concept of Ajax (asynchronous JavaScript and XML technology) begins the time prelude of page partial refresh so that developers can develop web application programs with stronger interaction. The paper illustrates the concrete application of Ajax and Hibernate to the development of E-shop in details and adopts them to design to divide the entire program code into relatively independent parts which can cooperate with one another as well. In this way, it is easier for the entire program to maintain and expand. © 2012 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

In order to embody the reuse significance of software reuse framework fully, this paper will analyze in detail about the single object model mentioned in the article "The overall design of software reuse framework" and induce them as add and delete and modify mode, check mode, and search and scroll and display integrated mode. Three modes correspond to their own interface design template, class and database design concept. The modelling idea helps developers clear their minds and speed up. Even laymen can complete the development task easily. © 2012 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
