Abstract: The concept of ideals play an important role in Hilbert Algebras in BCK-algebras, so here we will give some relationships between ideal, fuzzy ideal, commutative fuzzy ideal and weak ideal.

Abstract: According to the principle of the digital camera’s forming image, we measure the distance between the points on the target and digital camera respectively, then we construct the limited equation, and calculate the position relation between target and digital camera through this limited equation, then by using the coordinate’s transformation, we transform the coordinate which takes digital camera as original points into the coordinate which takes target as original points. After that step, we could fix the coordinate which compare to the target. Finally, we finish the fixation task of the doubled-sight digital camera.

Abstract: Let E be a real q-uniformly smooth and uniformly convex Banach space and K a nonempty closed convex subset of E. Let Ti : K ! K, i = 1; 2; : : : ;N be ki-strictly asymptotically pseudocon- tractive mappings with \N i=1F (Ti) 6= ;, where F(Ti) = fx 2 K : Tix = xg. Let fxng be the sequence generated by xn+1 = (1 ¡ ®n)xn + ®nTn [n]xn; where f®ng is a sequence in [0,1] satisfying certain conditions and Tn [n] = Ti n; i = n(modN). Weak and strong convergence theorems for the iterative approximation of common ¯xed points of the family fTigN i=1 are proved.

Abstract: With rapid growth of national economy, infrastructure construction maintains its vigorous development, but there are some serious problems in this field, for example, construction unit and supervision unit may conspire together to swindle governmental capital. This paper introduces some background which exists in construction project management system, analyses relation and benefit of project’s tripartite main body, and establishes conspiracy game’s utility matrix of construction unit and supervision unit by introducing game theory. By establishing conspiracy game model between construction unit and supervision unit, the paper mainly discusses conspiracy action which may occur between construction unit and supervision unit (rent-seeking and rent-creating), gets equilibrium probabilities of seeking rent and creating rent, and make some further analysis.

Abstract: In this paper, we study the infinite time interval backward stochastic differential equations (BSDEs) driven by a Lévy process. A existence and uniqueness theorem for solution of the BSDEs is established, which can be considered a generalization of existence and uniqueness theorem of BSDEs. A continuous dependence theorem for solutions of the BSDEs is also given.

Abstract: Because no commercial EMR system in the field of orthodontics is suitable for orthodontist’s purposes now, we study orthodontist’s daily workflow, analyze the requirements, and finally develop the EMR system, Decision-Support and Orthodontist Management for Peking University School of Stomatology. We adopt advanced Rich Internet Application (RIA), such as Flex, to implement business process, human-computer interaction and data visualization on the client-side according to orthodontist’s workflow; SSH (Struts, Spring, Hibernate), three popular Web design frameworks based on Java EE, to implement orthodontist’s business logic and data persistence on the server-side so as to develop low-coupling codes. And the EMR system is integrated with existing Resister, Ward and Drugstore information systems. The practice shows that the EMR system can fit seamlessly into orthodontist’s daily workflow and effectively replace current paper medical records.

Abstract: According to the imagery coordinate’s mapping relation between the three points’(A,C,E) geometric limited condition on target surface ( length, perpendicular) and the image’s coordinate on the imagery plane surface to construct non- lineable equation models, we make use of the method of abstracting the center of a circle to get the coordinates of the three points 、 、 .In order to improve the precision and decrease the quantity of operation, we take the accelerateNewton Newton iterative method to evaluate the original numerical value by adding its repeating times to increase the precision of model, then to solve out the numerical value of coordinates of the three points A,C,E on the target’s surface, on the basis of this numerical value, we can fix the solution of the target’s surface’s equation. Try to assure the precision of the constructed model through these erroneous values, meanwhile, to make out the concrete analysis about the model’s stability.
