Abstract: Automatic testing is very important for agile software development. There are some testing tasks can be finished by automatic tools, but most of them can not meet the actual needs of enterprises which is the direct reason of building an agile automatic testing framework named as Agilework. The structure, operation principle and building steps of the Agilework are descripted in details. The Agilework is a scalable framework which has high efficiency and flexibility. It can meet the requirements of the automatic testing in agile software development.

Abstract: Based on the discrete mathematics model, this paper analyzes and studies the artificial intelligence virtual technology of computer and verifies the feasibility and reliability of the model through the virtual numerical experiment of computers simulation. The first part of the article describes the key of computers artificial intelligence virtual process and virtual technology and discusses the analog signal and conversion process of digital signal and the visualization process. Base on this, this paper establishes the discrete mathematical model of computers logic. This model can determine the signal and issue digital signal and control instruction. At last, this paper designs a virtual computers simulation and verifies the reliability of the model through the successful control of multi-freedom of virtual human. It also has been extended to piano playing process and concluded the time visualization chart of the pianos frequency response event which provides a technical reference for the study of vocal performance process simulation.

Abstract: Based on the virtual computing principle of computers feature and compatible MCU logic unit of full asynchronous microprocessor, this paper designs computer simulation platform of ideological and political education. The platform has data mining and analysis module. In order to verify the reliability of the platform, we design the data analysis simulation experiment of ideological and political education. Through the calculation, we can get the MCU integration curve. According to the impact of ideological and political education on users, we use computational analysis module to draw thinking fluctuation curve of political ideological education. We also can get thinking step characteristics of Political and ideological education which has high reference value for the research of the ideological and political education.

Abstract: It is significant to develop a method to realize efficient broadcast transmission in wireless networks. Network coding is a promising technique in this scenario. In this paper, a multicast constellation design scheme using combination network coding (CNC) is proposed. This scheme employs CNC to guide the constellation design, under multi-objective such as multicast throughput and coverage performance. Through the analysis and simulation results, the design result can completely meet the design requirement.

Through the numerical simulation we obtain the curve of oil tank temperature and pressure with time. And through comparison of virtual computing results and experiment results, it verifies the reliability of the algorithm. At the end of this paper, we apply the multimedia virtual simulation technology to the basketball match, and analyze the technical parameters of the match. It provides the technical reference for the training of basketball players.

Abstract: Aircraft training simulator has integrated combat training ability not only needs to simulate the aircraft flight and radar, inertial navigation and avionics equipment, but also to generate realistic battlefield environment and visual effects, and to simulate the interaction between the system and the complex interaction. In the realization of the simulator, using HLA/RTI as its architecture and the supporting platform, make the device emulator is to achieve interoperability, can improve the system's flexibility and scalability. [ The target and the electromagnetic reflection characteristics of ground data and radar detection model based on the dynamic radar image generation. The blackboard model is based on the virtual machine technology, which is easy to modify and evolution of CGF system. [Combat aircraft is the main weapon platform in modern war, and aircrew training level is an important factor which affects the combat effectiveness of an aircraft. Research on the domestic and abroad aircrew training methods and training methods with simulate system, develops advanced technology, which can achieve close to actual combat to training effect and save a lot of training funds.

Abstract: ZigBee protocol is widely used in the internet of things. In process of related equipment development, the ZigBee protocol debugging is an important part, and ZigBee protocol analyzer is a vital tool for debugging. For the existing protocol analyzer cannot deal with the wrong frame well and cannot locate a specific field quickly, this paper designs a ZigBee protocol analyzer and implement it by using the technology of quick rollback and partial repainting, the main features of this system are as follows: lower computer supports a variety of ways to connect to superior computer; it can collect data packets for 16 channels of 2.4GHz band; it can significantly identify the wrong frame; also, it can present a specific field which debugger are interested. Test results show that this system is better able to deal with the wrong frame and locate the specific field quickly.

Abstract: To analyses networks, technologies of network protocol analysis are usually used. A new approach of protocols analysis is presented based on the combination mode of walsh function. It consists of three parts, such as the protocol structure characterization method, the hierarchical protocol analysis and the self-learning combination modes. After discussing the analysis process, an experiment shows the efficiency of presented approach.

Abstract: The rapid growth of application for low-cost, low power sensor nodes based on WSN brings its own challenges. SimpliciTI is a simple low-power RF network protocol that with open Source, flexibility, and low-cost, short development cycle and so on. Aiming at the blindness problem of channel migration when this specific frequency is noisy, We presented PSCP-FA(periodic synchronism and channel prediction Frequency agility) which accomplish the channel agility predictable. Furthermore, we evaluated the impact of energy of efficiency compared with S-MAC and FA. Our simulation results show that PSCP-FA performs better than S-MAC and FA.
