Abstract: Retracted paper: Biologists agree that real-time methodologies are an interesting new topic in the field of electrical engineering, and cryptographers concur. In this paper, we argue the emulation of voice-over-IP, which embodies the typical principles of crypto analysis. We motivate new homogeneous symmetries, which we call Niceness.

Abstract: Text classification has been a hot research in recent years. This text reviewed the history of text classification. It summarized some common classification methods and mainly introduced classification methods based on semantic. Especially, it elaborated the text classification based on ontology, the text classification based on similarity computation and the text classification based on latent semantic indexing.

Abstract: Traditional algorithm for mining association rules need to scan the database many times when mining association rules, which are inefficient and time-wasting. In the light of the defects of traditional algorithm, this paper introduces the improvement of community partition algorithm into the process of association mining and uses the Internet forum users’ data of a university as the object of the new algorithm for mining association rules. The experiment shows that the new algorithm can help optimize the data association rules mining and reduces the times and time of scanning the database, so the mining efficiency is greatly enhanced.

Abstract: Data dispersal mechanism is a group of basic working protocols for oceans of data processing and it plays an important role in enhancing system error correction and avoiding storage device failure. The data recovery availability of the client is the main design goal of data dispersal algorithms. The system storage and computing costs are also important factors for a data dispersal algorithm. In this paper, we discussed how to disperse data with the special properties as well as with acceptable system costs. We developed a universal approach to measure storage node availability based on state variables. After analyzed the existing data processing algorithms, we presented a new hybrid data dispersal algorithm using the above approach in detail evaluation. Two redundancy policies are adapted to storage node with different node availability. According to our analysis, this algorithm has its advantages in system storing and communication bandwidth costs.

Abstract: In this paper, the vehicle scheduling model in pooling pallet distribution was established, and the genetic algorithm for the problem was researched. In the algorithm, the genetic algorithm and the idea of ant colony algorithm are integrated in the proposed two crossover operators, and the appropriate values of parameters were determined by experiments.

Abstract: Retracted paper: In recent years, much research has been devoted to the exploration of write-back caches; however, few have studied the practical unification of local-area networks and Lamport clocks. Given the current status of atomic information, cryptographers clearly desire the exploration of the lookaside buffer. We describe new stable algorithms, which we call Rig .

Abstract: Retracted paper: The construction of linked lists is an unfortunate problem. After years of robust research into Byzantine fault tolerance, we validate the development of the transistor. In this paper we propose a virtual tool for enabling multi-processors (PilousGnu), verifying that active networks and massive multiplayer online role-playing games can interfere to answer this question.

Abstract: In order to meet the users’ demand of knowledge and use knowledge efficiently in the process of knowledge management,this paper adopts modeling methods of multilayer and multidimensional context tree to complete the establishment of the knowledge context tree, build the algorithm of the context entity similarity and realize the knowledge push, so that a kind of very valuable method for pushing knowledge has also been put forward.

Abstract: Spatial data is used to indicate the location, shape, size and its distribution information of the spatial entity in many respects. It can be used to describe the target from the real world, as it has the characteristics of position, qualitative and the relationship between time and space. Position refers to the known coordinates of space target is the only space location. Qualitative refers to the natural attributes of space target with which the location of target. Time refers to the space target which changes over time. Spatial relations are usually expressed using topological relations. Spatial data is a kind of point, line, face and entities such as the basic spatial data structure to represent the people rely on the data of the natural world. And the key technologies of the survey spatial database are the SQL technology, the arcSED technology, storage and indexing.

Abstract: In this paper, the average reprojection geometrical errors on all images of a spatial straight line is taken as the restructuring and optimization target function to ensure the optimal result to be acquired; a spatial straight line is expressed by use of the Plücker coordinates for the proposal of the analytical method of correcting the double linear restriction on the Plücker coordinates of noise-included spatial straight lines; during the optimization process, to ensure parameters that meet double linear restriction, the iteration renewal process is expressed by at least 4 parameters, to increase the precision of restructuring results. Experiments results derived from simulation data and real images have all demonstrated the high efficiency and precision of the algorithm proposed in this paper.
