An ARINC429 bus testing system is designed based on FFT processor, which aims at the technology of ARINC429 bus data communication. It controls tested module by controlling bus. In other words, the performance of ARINC 429 bus is tested by testing address bus and data bus. The testing system is based on ARINC429 bus specification and adopts universal ARINC429 special component DEI1016 and BD429 to...
In this paper, an iterative algorithm is established for solving a class of matrix equations with complex unknowns. By using the hierarchical identification principle, the gradient-based iterative algorithms are constructed to solve the equation AXB + CXHD = F and the coupled equations A1XB1 + A2XHB2 = F1 and C1XD1 + C2XHD2 = F2. The the convergence factor is presented to guarantee that the iterative...
As software and hardware have grown in functionality and complexity, the existing computer systems are confronting serious challenges with safety, dependability and reliability. Being one of the primary causes with responsibility for these challenges, the software-hardware interaction is advanced and widely studied in recent years. Unfortunately, none of the state-of-art researches has achieved widespread...
The main difficulty of Amazons games is the huge branch factor. Traditional NegaMax Search and Alpha-Beta Search can only search a few layers and can't improve the games effectively. Monte-Carlo Algorithm can improve the games but it needs a huge amount of computing. This paper studies applying UCT algorithm to the Amazons games to overcome this problem in order to balance the search efficiency and...
This paper introduces the present development and situation of computer games, especially in connect6. Through the regulations of computer games in connect6, it is described that main technologies and principles are existing in the connnect6 game. According to the algorithm and application of other mature computer games, the five steps of connect6 method and skill is improved to be advanced and modified...
This paper introduces the Chinese chess recognition algorithm based on computer vision and image processing. In order to simplify processing and enhance efficiency, the images of chessboard and chessman need preprocessing in advance. The steps of preprocessing include of transformation from color images to gray images, images filtering with mean filter or median filter, and binaryzation of the gray...

The UAV Air-Combat Decision problem has become one of the research focuses of the military field in the world. Firstly, this paper analyzes the specific process of the UAV Air-Combat Decision and...
The game of NoGo needs to be optimized its theoretical system and evaluation methods since it is been proposed in recent years. At present, most of the programs of NoGo are based on Monte-Carlo Tree Search (MCTS), but its programs are rarely based on static evaluation algorithm. In this paper, according to the rules and characteristics of NoGo, a static evaluation method has been put forward. In the...
Recent years, Monte Carlo and UCT (Upper bound Confidence for Tree) have been widely used in algorithms of computer games, and considerably improved computer Go programs. Phantom Go is a game with incomplete information and different with Go. The study of Phantom Go is just beginning. Most algorithms of Phantom Go applying Monte Carlo or UCT directly, but results are not quite satisfactory. In this...
The valuation of game situation was experimentally studied according to the characteristics of Einstein würfelt nicht!(EWN), and a reasonable evaluation method is obtained in this paper. In addition, this paper presents an optimized Monte Carlo algorithm based on the valuation of game. Finally, the optimized Monte Carlo algorithm played chess respectively with the Mini-Max algorithm and Monte Carlo...
Computational complexity is a branch of the theory of computation. It is used to measure how hard a problem is solved and the common measures include time and space. The classes of time complexity generally include: P, NP, NP-hard, NP-complete and EXPTIME; the classes of space complexity generally include: PSPACE, NPSPACE, PSPACE-hard and PSPACE-complete. Researching computational complexity of a...
In order to let information path selection in small world theory solidify, a path selection algorithm based on AHP(Analytic Hierarchy Process) for small world with three-weight is proposed in this paper. First, the small world model with three-weight which contain distance, connections and density between vertexes is established. Then we use AHP to set up a three-level hierarchy and use it to analyze...
Computer game, a new field of artificial intelligence, as the name suggests, is to make the computer learn to think and play chess games like human beings. As one of the important research field of the artificial intelligence, computer game, which is considered as the touchstone of the artificial intelligence, has brought many important methods and theories to the field. Connect6, is a newly introduced...
Computer game is an important search field of artificial intelligence. Dou Dizhu is a confrontational sports with cards in China. It is an incomplete information game. We analyze the process of Dou Dizhu and describe its computer game model in participator set, history set, participants function, information space, natural distribution, participant preference. This game model will be used to research...
Surakarta chess is one of Computer Olympiad chesses. Its Chessboard is irregular. The logical structure of Surakarta chess is studied. A new storage structure of realizing the computer game program of Surakarta chess is presented. Representation of chessboard and chessman are presented by using the new storage structure. It is quite easy to judge the position relation of chess pieces with the storage...
Image segmentation is a fundamental process in computer vision applications. This paper presents a novel method to deal with the issue of image segmentation. Each image is first segmented coarsely, and represented as a graph model. Then, a semi-supervised algorithm is utilized to estimate the relevance between labeled nodes and unlabeled nodes to construct a relevance matrix. Finally, a normalized...
Conventional control interfaces such as joystick, keyboard, and mouse are widely used in teleoperation. However, they are not operated by some users such as who have disabled hands. This paper proposed an eye gaze tracking system for teleoperation. The eye gaze tracking system is based on non-intrusive, visible light, iris center corneal reflection (ICCR) and 2-D mapping-based gaze estimation. In...

On the basis of reverse search technology, the software and hardware...
According to the continuity and monotonicity of industrial real time data, an auto regression compression method (for short ARCM) is proposed. Firstly, the auto regression model of a group of sampled sequence is established. Secondly, the next sampled data can be predicted by the model. If the error between the actual data and the predictive data is in the allowable range, we save the parameters of...
