According to the requirement of reliability simulation technology development, and on the basis of summarizing the research results of reliability simulation technology, a framework of reliability interactive simulation (RIS) based on high layer architecture (HLA) is proposed. The framework which is mainly structured on HLA, combines the interactive simulation technology with reliability analysis...
This paper introduces a hybrid SVD-Krylov technique based on the balanced truncation - proper orthogonal decomposition (BT-POD). The method combines the best features of the two categories, namely offers error controls and indicators while preserving the efficiency of Krylov MOR. The most time consuming step related to the POD sampling is embarrassingly parallel, making the method suitable for multi-core...
Current propagation models used in network simulations neglect obstacles of a propagation environment and employ over-simplified assumptions that the received signal strength is a simple function of distance and the transmission area of a node is circular. These assumptions are in contradiction with the actual tests and the measurement results. To run reasonable simulations for evaluating the performance...
The Technical Barriers to Trade (TBT) is an important problem faced to the export of China. Based on the number differences of TBT notifications between countries, we propose the concept and computational method of the technical barrier coefficient. By means of price-production and price-demand functions, a trade model with a developed country and an under-developing country is designed. The available...
Reconfigurable system provides both flexibility of software and performance of hardware. It is a significant trend in embedded application domain. Some new reconfigurable technologies and technology-dependent tools have been developed, but the whole design flow for run-time reconfigurable systems with real-time operating system support is not proposed. RTOS plays an important role in the system and...
By analyzing the topological relationships between network elements, this paper extends a turn-based algorithm for the network loading of logit type, which has a structure similar to Dial's algorithm. Based on the conservation of flows on links, the algorithm computes directly the link flow and turn flow pattern that not only agrees with the logit path-choice process but also takes into account the...
The paper develops and discusses a conceptual model for a mixed reality-based remote collaborative system (MR-Collab) based on motivated learning agents. The proposed MR-Collab system is described in details as well to help better understand this model. Self-development agent based on previous work is an intelligent agent, which not only receives information from sensors in the environment, but also...
Event evolvement and topic shifting can affect the accuracy of event tracking. A dual-center event model is proposed to improve the event tracking process by adjust the some attributes of event dynamically. The detail of maintenance of the model is given. The experiment results show that the dual-center event can improve event tracking effectively under the condition of event evolvement and topic...
The problem of ranking has recently gained attention in data learning. The goal ranking is to learn a real-valued ranking function that induces a ranking or ordering over an instance space. In this paper, we apply popular Bayesian techniques on ranking support vector machine. We propose a novel differentiable loss function called trigonometric loss function with the desirable characteristic of natural...
The characteristic of high precise and real-time simulation of satellite navigation observation was analyzed in this paper. And the principle, function composing and high fidelity mathematical models used in observation simulation were studied. Because of the different time constrains to realize different models, the architecture of simulation system was mainly divided into three parts: namely non...
With the steady development of WiMAX based broadband wireless access networks, complete and accurate simulation studies become crucial. In an effort to further improve our ns-2 simulation model for mobile WiMAX, we have implemented a selective repeat automatic retransmission request (SR-ARQ) mechanism into our model and evaluated its performance and accuracy. In this paper, we present the design and...
The traditional language model takes the multi-topics document corpus as the research target. In order to avoid the interference brought by the multi-topics problem, this paper focuses on the domain specific Information Retrieval (IR). In domain specific IR, different terms are considered to take different contribution degrees to the final query result. So the terms in a document can be divided into...
The paper analyzed key problems about the model and framework of urban emergency response system. It aims to present a new model and framework of urban emergency response system. The new model is based on decision-system. And in the framework, it includes the procedure of creating contingency plan. In this paper, it expatiates on emergency affairs, layers and functions and framework of the platform...
The World Wide Web is a major source of the news now. The news analysis play more and more important roles in the political decision, financial analysis, invest decision, market forecast and so on. This paper proposes a news analysis system based on the hall for workshop of metasynthetic engineering. In this system, in order to analyses online news, the news articles are active fetched, and being...
In practical, there exists a problem in traditional maximum likelihood estimation (TMLE) that is the great computational burden. Based on the decorrelation property of discrete wavelet transform (DWT), we propose and evaluate multi-scale maximum likelihoods estimation (MMLE), and apply it to a kind of long memory processes with broad application background. Simulation results show that under some...
