Mining frequent patterns plays an important role in mining association rules, correlation, multi-dimensional patterns, etc. Since any nonempty subset of a maximal frequent itemsets also is frequent, it is sufficient to mine only the set of maximal frequent itemsets. In this paper, we still base on the FP-tree and propose an optimized algorithm to mine maximal frequent itemsets. By analyzing the data...
This paper investigates some properties of two-way alternating pushdown automata with only existential (universal) states which have inkdots and sublogarithmic space. We show, for example, that for sublogarithmic space-bounded computations, multi-inkdot two-way alternating pushdown automata with only existential states are incomparable with the ones with only universal states, and the classes of sets...
In this paper, we analyze MIPS instruction format-, instruction data path-, decoder module function and design theory basend on RISC CPUT instruction set. Furthermore, we design instruction fetch (ZF) module of 32-bit CPU based on RISC CPU instruction set. Function of IF module mainly includes fetch instruction and latch module -, address arithmetic module-, check validity of instruction module-,...
This paper analyses structure and algorithm of floating-point ALU, and implements multiplication and division operation in the homo-hardware circuit. The floating-point multiplication and division ALU supports floating-point number according with IEEE-754 standard. This ALU adopts 4-level pipelining structure: '0' operation number check, exponent addition and subtraction operation, fraction multiplication...
Kalman filter is introduced into the neuro-fuzzy deducing system (NFDS) operation to attenuate disturbances in measurement data. Both of Lidar and infrared radar data sets will be engaged into data fusion, because there will exist defective data points within both of which owing to the respectively distinct running mechanism. Data confidence estimator of NFDS derived from contextual information (CI)...
It is recognized within data fusion domain that the main challenge in devising gradient order fusion algorithm is to provide a feasible architecture in fusion system, which will comprise concerned entities in diverse subject-specific fusion model, besides, the characteristics, fusion situations and interrelations among system components have been demonstrated the key factors in the decomposition in...
An elaborately designed software architecture is put forward based on fuzzy sets theory (FST), which is specialized in multiple sensor fusion and mechanism failure diagnosis. Besides, when confronted with multiple fault signals, fusion parameters can be dynamically adapted based on principles of fuzzy soft clustering so as to promote immune ability in artificially mechanical systems. The key point...
The exterior of Environmental resources decide that the Energy consumption and reducing pollutant emissions can restrict and improve the way of Production and life by means of energy and environmental control policy. Because the existing environmental policy can not restrain the over-consumption of energy and deteriorating environmental situation phenomenon fundamentally, we establish a BP neural...
Construction enterprises win the project by construction project bidding .In present system of biding ,the threshold bidding cost directly impacts on bidding for quotation price of winning the tender, so it is very critical to design reasonable cost threshold in completive-bidding .There are many factors that influence the construction cost, which make construction cost to have the character of the...
Construction project bidding is a kind of transaction way of construction project the most widely used ,the bidding is a closed price auction, the game among the bidders and the tenders belongs to a kind of non-cooperation and incomplete static game and so does it among the tenders. According to the special rules of bidding, the game theory is put into construction project bidding ,the game model...
The paper focuses on examining the moderating effect of environment dynamism on the relationship of interlocking directorates and the firmpsilas output.The results indicate that in a highly dynamic environment the output of the firms in the center of the social networks constituted by interlocking directorates would be negatively affected.Such a study should shed light on our understanding of Chinese...
In this paper, a filled function approach for constrained global optimization (FFACGO) is proposed. It is a combination of the idea of filled function method in unconstrained global optimization with the concept of penalty function in constrained optimization. Moreover, this FFACGO can be easily actualized with a process that aims at successively finding better optimizer. The performance of the FFACGO...
By the theory of measure and linear algebra, this paper shows that the following property holds for almost all 2-player finite simultaneous games: for any Nash equilibrium, the numbers of pure strategies assigned positive probability by two players are equal. Moreover, if all the equilibria of the game are quasi-strong, the number of equilibria of the game is finite and odd.
This paper presented an accounting and charging system based open grid services architecture (OGSA), which developed with an emphasis on a consistent data model and easy integration into existing scheduling at a few independent resources providers to use under various grid environment. This accounting and charging system mainly addresses to resolve the problem of accounting and charging of resources...
An improved Fish-Search algorithm was proposed for airplane route planning of a class of Plane-Missile cooperation. The mathematical description of this class of cooperation was introduced. Comprehensively considered such key factors of the cooperation as inter-visibility, threat, maximum distance and relative orientation, the constraint conditions and evaluation index were constructed. According...
