Abstract: To enhance human interaction with machines, research interest is growing to develop a Brain-Computer Interface (BCI), which allows communication of a human with a machine only by use of brain signals. In this paper, one type of android RPG game was designed for application of brain computer interfaces.

Abstract: In this paper, network layer is based on ZigBee standard. Network establishment and routing of wireless sensor network have been detailed in ZigBee network transmission. It has described data in tree topology and routing in mesh topology network respectively. It has provided with an example. There is no corresponding route in its routing table information, when the source device needs to send a message to the destination device. Source network layer initiates route discovery process. The programming examples are verified on this basis of the theory.

Abstract: Wavelet decomposition is a commonly used tool, signal analysis using the wavelet decomposition, can put the source according to their demand is decomposed into different frequency signals, so as to provide convenience for the feature extraction and identification in this paper, the EEG signals, using the theory of wavelet decomposition is calculated, look from the calculation results, the wavelet decomposition can be used for feature extraction of EEG signals as well.

Abstract: Based on the RGBD sensor, this passage suggested a method named ‘Control-right Management’ to reduce the Interaction Information in order to bring better communication efficiency of an Analog Digital Television System. This system was base on fingertip, dynamic and static hand gesture recognition,and it can be controlled by person in the mid-air. And then split and recombination of different operation elements as “Complex Group Gesture” to improve the system’s availability and users experience. According to the Goals Operators Methods Selection Rules(GOMS) model we analyzed the operation step by step and found the redundant process, then reduce the operation time and steps to give the users better availability and users experience. Calculated by the formula of interaction efficiency, the changed operation showed more efficient than before.Finally we take some experiments of our methods and propose several specialize quantitative evaluation methods that can be used in the field of Digital Television System.

Abstract: For scientifically distributing paths of relay protection services for power optical-fiber channel, ensuring the security of each path, meanwhile, reducing the amount of links that carry too many services, the improved Dijkstra algorithm is offered. As a preparation for path selection, the security are mapped to the weights of nodes and links; to avoid some links overloading, modify link weight by a dynamic weight update function during the search process; and the degree of security risk equalization is proposed to assess the security status of the whole network.

Abstract: The link of bidding is the key to large quantities of goods and materials purchasing of the railway. To meet the requirements of the procurement bidding, both sides are required to complete the process of bidding, consultation, and evaluation within the set time online synchronously. This paper introduces the real-time bidding based on MooTools without page refreshed.

Abstract: Without the railway material supplies, the rail traffic construction cannot make rapid development. Online material procurement bidding saves more time and cost for the personnel than on the site ever before. This paper introduces the interactive consultation based on MooTools long polling technology.

Abstract: Workflow is a kind of automatic execution of business process partly or fully, according to a series of rules, documents, information or tasks which can be transferred and executed in different executor such in Data center. Modeling process workflow management model on ontology is divided into following steps based on: Determine professional field and category of Ontology; Important terms and concepts; Definition of class and class hierarchy; Define class attributes and surface properties, Because user demand always changes according to the development of economic, In workflow management system, user demand migration prediction system can give some help. There are two subsystems: Data Mining subsystem and migration of recommendation subsystem.

Abstract: Chroma Keying is a common method of Keying, Adobe Ultra which as known as Virtual Studio software is a common software that using Chroma Keying. This paper describes the principle and method of Chroma Keying in Adobe Ultra, the application in several different cases and comparison of several common Chroma Keying software.

Abstract: The .NET platform is a very important commercial software platform, so understanding its protection and crack becomes very necessary. In the introduction, this article briefly introduces the platform, analyses the status quo of platform crack at home and abroad and what technology need to crack. Detailed descriptions of the crack .NET assembly principles and analytical methods for cracking tools are also described. Based on the existing methods, it provides an analogical method of crack, and it worked on a famous commercial software well.
