Multifocus Image Fusion Combined Multiwavelet with Contourlet
Yuelin Zou,You Guo,Liang Tian
Research Journal of Applied Sciences, Engineering and Technology , 2012,
Abstract: In this study, we propose a new image fusion method by combining Multiwavelet with Contourlet transform. Firstly, transform the source multifocus images successively by Multiwavelet and Conotourlet. Secondly, we employ the LEM rule to fuse the lowpass coefficients and PCCN rule to fuse the hightpass coefficients. Finally, inversely transform the fused coefficients successively by Contourlet and Multiwavelet. This algorithm is obviously better than Multiwavelet or Contourlet method in the fusion effect and the objective criterion of MI and QAB/F.
LED Digital Image Design and Production in Large Stage Performance—Take “Shanghai Science and Technology Festival” Series of Performances for Example  [PDF]
Yuelin Hu
Art and Design Review (ADR) , 2018, DOI: 10.4236/adr.2018.63015
Abstract: In recent years, LED digital image design and production in large stage performance is taken more seriously. It not only provides the background atmosphere for the performance, but also becomes part of the stage performance in close combination with the performance. The subject summarizes the work flow of LED digital image design and production in stage performance and introduces the design and production methods of stage LED video through taking series of performances of Shanghai Science and Technology Festival for instance. LED digital image design and production in large stage performance is a new study field that integrates video clipping, special effect production and 3D synthesis technology which enrich the stage performance style and improve the visual effect of stage performance.
On the Objective Orientation of Young Students’ Legal Idea Cultivation-Reflection on Legal Education for Chinese Young Students
Yuelin Zhao
Journal of Politics and Law , 2009, DOI: 10.5539/jpl.v2n3p71
Abstract: Legal idea, as a kind of rational cognitive state, is the spiritual core of national laws. Traditional article- remembering legal education is either necessary or meaningful in practice. The cultivation of young students’ scientific legal idea is vital for the success of national law modernization. In practice, to cultivate young students’ scientific legal ideas, we should strengthen the recognition to the citizen nature of laws and the social functions, pay attention to people’s desire, and emphasize on citizen rights’ actualization and protection, especially the actualization of citizens’ private rights.
Comment on "How to Realize Uniform Three-Dimensional Ellipsoidal Electron Bunches"
Yuelin Li
Physics , 2008,
Abstract: Via systematic numerical simulation we found that the recently propose 'Pancake' scheme [O. J. Luiten et al., Phys. Rev. Lett. 93, 094802 (2004)] does not generate a beam desired for low emittance, even when compared with the more traditionally accepted cylindrical beam geometry.
"Fractal Expression" in Chinese Calligraphy

Physics , 2008,
Abstract: We show that from historical record and mathematic analysis, "fractal expressions" may have been a conscious pursuit at least one thousand years ago as an element of beauty in ancient Chinese calligraphy.
Multiobjective Differential Evolution Algorithm with Multiple Trial Vectors
Yuelin Gao,Junmei Liu
Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/172041
Abstract: This paper presents a multiobjective differential evolution algorithm with multiple trial vectors. For each individual in the population, three trial individuals are produced by the mutation operator. The offspring is produced by using the crossover operator on the three trial individuals. Good individuals are selected from the parent and the offspring and then are put in the intermediate population. Finally, the intermediate population is sorted according to the Pareto dominance relations and the crowding distance, and then the outstanding individuals are selected as the next evolutionary population. Comparing with the classical multiobjective optimization algorithm NSGA-II, the proposed algorithm has better convergence, and the obtained Pareto optimal solutions have better diversity.
The Performance of Synchronization Algorithm in Real-time OFDM—PON System
Yuelin Du,Jingxian Zhang
TELKOMNIKA : Indonesian Journal of Electrical Engineering , 2012, DOI: 10.11591/telkomnika.v10i7.1576
Abstract: In OFDM-PON system, the synchronization signal is very important. We use synchronization signal to get a whole OFDM signal. Due to the real-time system, we need to get the fast change signal. So get a true signal is very important and very hard. That is to say, we need to design an excellent algorithm to get finish this demand. This is another point of this project. In the paper, the author designed a new algorithm to solve the problems. we use some simulations to compare the performances of different algorithms to get the further understanding. In the experiment, we use more detail algorithms to estimate if it is useful in real-time OFDM-PON system. When the SNR is 10, we can get the synchronization signal correctly.
Price Performance and Liquidity Effects of Index Additions and Deletions: Evidence from Chinese Equity Markets
Yuelin Li,Mehdi Sadeghi
Asian Journal of Finance & Accounting , 2010, DOI: 10.5296/ajfa.v1i2.193
Abstract: We investigate the impacts of index revisions on the return and liquidity of Chinese equities, using a sample of 69 stocks added to or deleted from the S&P/CITIC 300 index over the period October 2004-August 2007. Our findings show that stock prices respond positively to index additions, and negatively to index deletions. Furthermore, our study provides evidence in support of a long-term improvement in liquidity for both stock additions and stock deletions. Overall, the results are largely consistent with prior empirical findings, and also appear to be in line with the predictions of some behavioral finance models. Keywords: Chinese equity market, index addition and deletion, event study, abnormal returns, liquidity changes. JEL Classifications: G14, G15
Men's values-based factors on prostate cancer risk genetic testing: A telephone survey
David J Doukas, Yuelin Li
BMC Medical Genetics , 2004, DOI: 10.1186/1471-2350-5-28
Abstract: Telephone computer-assisted interviews of 400 men were conducted in a large metropolitan East-coast city, with subsequent development of psychometric scales and their correlation with intention to receive testing.Approximately 82% of men interviewed expressed that they "probably" or "definitely" would get genetic testing for prostate cancer risk if offered now. Factor analysis revealed four distinct, meaningful factors for intention to receive genetic testing for prostate cancer risk. These factors reflected attitudes toward testing and were labeled "motivation to get testing," "consequences and actions after knowing the test result," "psychological distress," and "beliefs of favorable outcomes if tested" (α = 0.89, 0.73, 0.73, and 0.60, respectively). These factors accounted for 70% of the total variability. The domains of motivation (directly), consequences (inversely), distress (inversely), and positive expectations (directly) all correlated with intention to receive genetic testing (p < 0.001).Men have strong attitudes favoring genetic testing for prostate cancer risk. The factors most associated with testing intention include those noted in past cancer genetics studies, and also highlights the relevance in considering one's motivation and perception of positive outcomes in genetic decision-making.There are several factors to consider in undergoing genetic testing for cancer risk: potential benefits, possible risks, psychological distress, and the uncertainty in subsequent decision-making about prophylactic interventions [1-9]. While the health professional's assessment of the potential benefits and harms frames the disclosure of informed consent, the patients' values and expectations are intrinsic on the decision-making process. Current understanding of these values and expectations has been primarily derived from patients considering genetic testing for breast and colorectal cancers [10]. It remains unclear how these same factors may influence men's decision m
The Power of Assumptions  [PDF]
Yongchen Zou
Modern Economy (ME) , 2011, DOI: 10.4236/me.2011.24056
Abstract: This paper examines computational merits provided by assumptions made in scientific modeling, especially regression, by trying to exhibit abstractly a model deprived of those assumptions. It shows that the principle of Occam’s Razor has been mistakenly used as model developers’ justification to keep scientific models “as simple as possible”, and that the cost of inflating computability is truncation of model robustness.
