This paper presented a fast algorithm which could measure similarity between two meshes interactively. The algorithm was based on CUDA (Compute Unified Device Architecture) technology. In order to fully utilize the computing power of GPU, we developed parallel method to construct uniform grid for fast space indexing of triangles. Special data structure was designed on device end to overcome the disadvantage...
The platform and community of social network have become a major trend of people's work and life, and collaborative filtering is the most popular method currently. This paper analyzed the disadvantages of the traditional collaborative filtering, and proposed an improved algorithm of personalized recommendation based on collaborative filtering in SNS, which increase the efficiency of the recommendation...
Due to the developing of network technology, the increasing size of enterprises, the rising of cloud computing, the monitoring of large scale distributed computing is more and more important. The studies of Distributed Monitoring on resources, programs, services, home and abroad, are lack of user-configurable and run-time management. This paper proposed an ECA rule-based configurable monitor frame...
We have developed a design-support system which enhances design ideas by activating divergent thinking and convergent thinking of a designer, and offers a natural user interface that does not interrupt the thinking of a designer using the faculty of a computer. The system is composed of three user interfaces (UI)-a historical-view UI which analyzes partitions and branches of a design process automatically...
Traditional approaches to apply tabu search method typically require formulating an algorithmic structure for each individual problem. Based on algebraic specifications, the paper presents a unified and mechanical framework for implementing tabu search algorithms for combinatorial optimization problems. We define a generalized specification using high-order functions to describe search strategies,...
Radio Frequency Identification (RFID) and Electronic Product Code (EPC) have received great attention in recent years. The EPCglobal Network uses the Internet to transmit EPC data gathered from RFID tags. Although EPC Network is used to capture and share EPC-related data within a supply chain, the information discovery mechanism is still to be determined so far. In this paper we propose a novel RFID...
This paper presents a new technique for decomposing a binary shape which provides a hierarchical description of the shape. Associated to the decomposition, a hierarchical reconstruction procedure enables to recover the general aspect of the object as well as its exact original shape. A mathematical modeling of the procedure allows us to demonstrate that the reconstruction is exact. Simulation results...
With the rapid development of new media, such as computer and Internet, extract valuable entity attribute information from Web text can be significant. Aiming at this problem, this paper puts forward SALmap, this model calls seed method at first, which will create common candidate attribute label sets by defining data format rules. Then we construct the mapping relationship between the attributes...
Although static typing provides early type error detection, better legibility and abstraction, and more opportunities for compiler optimizations, dynamic typing supplies a high degree of runtime adaptiveness, providing an agile and interactive development suitable for rapid prototyping. In this article, the minimal core type system of a programming language which main aim is to provide the benefits...
In the real world, uncertain data exist exoterically, as in many area of application, it is impossible to express data with uncertainty of one hundred percents. The uncertainty is inherent in these systems due to measurement and sampling errors, and resource limitations. The flexibility of XML data model allows a more natural representation of uncertain data compared with the relational model. The...
The popularity of stroke-based image/video appearance editing is increasing in image processing field because of the intuitive, easy-to-control interactive interface. In this paper, we propose a new approach to editing natural image that adopts a stroke-based workflow. In our framework, the user paints a few simple brush strokes on region of interest and specifies edit value on each region. These...
General-purpose computation on graphics processing units (GPGPU) has become a popular field of study. Due to its high computing capacity and relatively low price, GPU has been an ideal processing unit for many scientific applications, among which is N-body simulation. According to the published papers, a simple O(N^2) algorithm of N-body simulation has achieved some enhancements, but tree-algorithm...
MP4 is a popular kind of multimedia container format. Most of multimedia players can play MP4 files. Since multimedia player is an embedded system with limited CPU and memory, it is very important to improve the efficiency of parsing MP4 metadata. In this paper we provide an optimized method for parsing metadata. The experimental result shows that the optimized method can obviously lower down the...
We present a new method for handling data skews in the database operation, relation joins. Recently, Graphics Processing Units (GPU) has become popular among high performance computing research and is used to accelerate the execution of database operations. Various parallel algorithms are developed in the past years with emerging of multi -core processors. Coordinate Module Distribution (CMD) is originally...
Logistics industry is becoming a more and more important field needed to be concentrated for all kinds of enterprises to reduce their own operation cost, and shorten their delivery time and so on. How to change the complicated logistics problem into abstract network model is elucidated here. Firstly, a directed graph G = (V, E) is used to describe the general logistics problem with some common restrictions...
In order to describe the dependence structure of the two relief factors of debris flow of main channel length and drainage height difference, this paper provides an ordinal sum of a class of Copulas, such that its concordance measures of Kendall's τ and Spearman's ρ being suitable for the data. The parameters in Copulas are calculated to get some specific Copulas, which can be better fitting to the...
In this paper, an active RFID real time location system based on fingerprint algorithm was founded. Two typical scenarios were chosen including ideal environment and complex environment to test the performance of the location system. Certain parameters were considered while evaluate the performance of the location system. Finally, the result shows the performance in different conditions.
As an advanced on-board data transmission protocol, Avionics Full Duplex Ethernet (AFDX) was initiated by Airbus in the evolution of its A380 Aircraft. In this paper, we deduce several properties of an AFDX network and present an AFDX System Integration Algorithm (ASIA) to guide the topology design of an AFDX network as well as Virtual Link (VL) parameters determination. We also propose an Integrity...
This paper introduces “population migration” idea and proposes an improved multi-population genetic algorithm based on population migration, which differed from tradition multi-population genetic algorithms that only improve the crossover and mutation operator. The new algorithm provides a population adjusting strategy based on population migration to adjust the population size automatically. Firstly,...
