In the biomedicine domain, a large number of papers are published every day, which is crucial to search for the relevant answers for the user's query. However, documents are not exactly what the users want. Instead, snippets, small segments from the documents, are more proper to meet the requirement of the users. Hence, this paper proposes a biomedical snippet retrieval framework to exactly locate...
Test case is one of the most important part of software testing. Reusing available test cases is an effective means to reduce the cost and improve the efficiency of software testing. In order to efficiently reuse test cases, a unified and standard format to describe test cases is needed. Therefore, this paper presents a reusing method based on ontology. The test case ontology is created by Protégé...
The seasonal fluctuation of AVI has significant impact on economic growth. Based on the methods of Directional Statistics, this paper analyzes AVI in Shaanxi Province between 2006 and 2010. Distribution types are ascertained by using von Mises distribution tests, which is submitting to bimodal von Mises distributions. Correspondingly, the result indicated that the AVI in Shaanxi Province has a character...
A Petri Net is a graphical and mathematical modeling approach used to describe the transition of states for an information system. This paper presents a novel technique to generating test cases using a Colored Petri Net (CPN) model. The state space of a model based on CPN provides a solid basis for test cases generation in a form that can be easily manipulated. This technique is based on three testing...
In order to solve an intra-system interface for chip-to-chip and board-to-board communications and meet the explosive demand for higher bandwidth and more efficient signal processing and data transmission in typical embedded system, here is an active demand that adopting a new system interconnect technology to ensure that bus performance continues to increase. The RapidIO is proposed in the paper...
Global optimization process can often be divided into two subprocesses: exploration and exploitation. The tradeoff between exploration and exploitation (T:Er&Ei) is crucial in search and optimization, having a great effect on global optimization performance, e.g., accuracy and convergence speed of optimization algorithms. In this paper, definitions of exploration and exploitation are first given...
To study the progress risk of IUR commissioned R&D project, this paper identifies progress risk source first, then forecasts the R&D time required in total by constructing GERT network model of R&D flow. In the quantitative analysis, the mason formula is used to compute the transfer function of the GERT, and the moment generating function is used to compute the probability distribution...
