In this paper, a hybrid parallel computing framework is proposed for video understanding and retrieval. It is a unified computing architecture based on the Map-Reduce programming model, which supports multi-core and GPU architectures. A key task scheduler is designed for the parallelization of computation tasks. The SVM method is used to train models for video understanding purposes. To effectively...
Soil erosion prediction information system is a powerful tool to analyze and process the information of soil erosion and quantitatively forecast erosion. The logical structure and function of Daqinghe Basin soil erosion prediction information system were discussed by comprehensive analysis of system requirements based on a variety of spatial scales in Daqinghe Basin, which will lay the foundation...
Situation assessment (SA) is one of the important processes in military decision. As a component of battlefield data fusion and decision support, SA is not easy to be realized ideally by using one particular technology in practice. Like any other complex military process, it requires the cooperation of lots of information processing technology. This paper describe a mechanism for constructing probabilistic...
We combined a cylinder with deformation and accomplished the visualization for creating animation of the growth of fruit from opening flower to yield fruit. The beginning model is a cylinder that simulate plant stem, and adds perturbation function to the cylinder surface in the direction of the unit surface normal. We may distort a cylinder to the geometry shape of flower and fruit. The perturbation...
Embedded vector processor is a kind of high-performance parallel processor. Pipeline design is a key technology in embedded vector microprocessors. This paper proposes a new modeling method for vector processor pipeline using open queueing network by instruction set feature of vector processor. According to instruction set distribution of vector processor in the practical projects and owing in the...
Most ID-based AKA protocols require that all parties are members of the same domain. In this paper, we present a new ID-based AKA protocol between members of distinct domains, which makes use of a new technique called twin Diffie-Hellman problem proposed by Cash, Kiltz and Shoup. It is inspired on a new ID-based two-party authenticated key exchange protocol proposed by Hai Huang and Zhenfu Cao. We...
Wikis are proven to be simple yet efficient tools for asynchronous collaboration where multiple users can collaboratively edit shared web documents. While desktop users are comfortable with text-based wikis, the latest developments of 3G networks and smart phones begs the question what is the appropriate model for wiki collaboration on mobile devices which can accommodate mobile user behavior? The...
This paper describes the workflow authorization model for workflow management system, which integrates RTBAC and multilevel security model, and presents authorization model for a multilevel security workflow in the multilevel secure environments. The model adds the presentation of security level and task dependence and reforms the authorization rule for the improved model. At last, analyses the model,...
Sticker model was a popular computing in the area of DNA computing. The separate operation was one of the important operation in this model. Adleman-Lipton DNA computing model was belong to sticker model, but, it was not convenient to use separate and multi-separate operation in Adleman-Lipton model. In order to solve this problem, extended separate technology and extended multi-separate technology...
This paper demonstrates the linkage between logistics system simulation and teaching mode, and explores new teaching methods and teaching ideas. It puts emphasis on analyzing the application of logistics simulation technology in the logistics system and exploring appropriate teaching modes of logistics system simulation. We make a point of the application of logistics system theory knowledge and the...
We propose a novel resource demand model and a BFS-based algorithm for multi-domain L1VPN. The proposed model and algorithm are implemented on AMSON testbed by combining PCE and service plane, and verified by experiment results.
In this paper, we present a distributed execution control framework (DECF) for seismic processing. The DECF framework employs a coarse-grained data-parallel execution model within a cluster environment and achieves high throughput. The DECF schedules processing modules written as sequential programs to run simultaneously on multiple computers, or multiple CPU cores. The DECF hides the messy details...
Aiming at the problem that self-learning ability of the current system usually appears weak during service discovery, a novel artificial immune system (AIS) based service match model is proposed, which is based on the reference to the principles of cellpsilas mutation, evaluation and the quadratic response abilities, as well as simulation on the antibody-antigen identification mechanism. Theoretical...
We propose a simple and effective modeling method for creating animation opening flowers. Because the detailed geometry of flower petals is defined by a base shape deformation, we simulate the development of petal based on deformation and emulate its growth by change the deformation parameters. The structural arrangement of flower petals is established by the L-system that produces natural looking...
Machine transliteration is to translate the proper nouns in the source language according to its pronunciation into the target language. Recent orthographical based approach has improved the performance of machine translation significantly. Focusing on the transliteration unit alignment that provides a fundamental parameter for the model, this paper adopts a semi-supervised EMD approach-applying discriminative...
Markerless human motion capture has received much attention in computer vision and computer graphics communities. A hierarchical skeleton template is frequently used to model the human body in literature, because it simplifies markerless human motion capture as a problem of estimating the human body shape and joint angle parameters. The proposed work establishes a skeleton based markerless human motion...
Timed asynchronous circuits are efficient in performance and power consumption. Traditional performance analysis method can not analyze timed circuits efficiently. In this paper, we model timed circuits using timed Petri net and digraph. We studied the mean cycle time of timed Petri net model. The upper bound and lower bound of mean cycle time were given. Then we proposed an algorithm for timed circuits...

Security trust model is an important research topic for the P2P application. This paper firstly analyzes the existing P2P network security trust models, and then puts forward a new P2P recommendation trust model based on the network of social relationships. The model provides different types of services to show the userpsilas interest in different areas, and gives recommendation based on the interested...
Along with the development of wireless technology and especially 3Gpsilas throw into commercial, the mobile value-added services gradually popular used, such as mobile automatic question and answer (Q/A) system. But the current mobile Q/A system mainly based on FAQ database, the question and answer can not be validated and updated by itself. So this paper attempts to implement a p2p based model updatable...
