Investigating natural-inspired applications is a perennially appealing subject for scientists. The current increase in the speed of natural-origin structure growth may be linked to their superior mechanical properties and environmental resilience. Biological composite structures with helicoidal schemes and designs have remarkable capacities to absorb impact energy and withstand damage. However, there is a dearth of extensive study on the influence of fiber redirection and reorientation inside the matrix of a helicoid structure on its mechanical performance and reactivity. The present study aimed to explore the static and transient responses of a bio-inspired helicoid laminated composite(B-iHLC) shell under the influence of an explosive load using an isomorphic method. The structural integrity of the shell is maintained by a viscoelastic basis known as the Pasternak foundation, which encompasses two coefficients of stiffness and one coefficient of damping. The equilibrium equations governing shell dynamics are obtained by using Hamilton's principle and including the modified first-order shear theory,therefore obviating the need to employ a shear correction factor. The paper's model and approach are validated by doing numerical comparisons with respected publications. The findings of this study may be used in the construction of military and civilian infrastructure in situations when the structure is subjected to severe stresses that might potentially result in catastrophic collapse. The findings of this paper serve as the foundation for several other issues, including geometric optimization and the dynamic response of similar mechanical structures.

Random forest classifier combined with feature selection for breast cancer diagnosis and prognostic

引用

Journal of Biomedical Science and Engineering 2013年第5期6卷 551-560页

作者： Cuong nguyen Yong Wang Ha nam nguyen College of Technology Vietnam National University Hanoi Vietnam School of Business and Administration Chongqing University Chongqing China

As the incidence of this disease has increased significantly in the recent years, expert systems and machine learning techniques to this problem have also taken a great attention from many scholars. This study aims at diagnosing and prognosticating breast cancer with a machine learning method based on random forest classifier and feature selection technique. By weighting, keeping useful features and removing redundant features in datasets, the method was obtained to solve diagnosis problems via classifying Wisconsin Breast Cancer Diagnosis Dataset and to solve prognosis problem via classifying Wisconsin Breast Cancer Prognostic Dataset. On these datasets we obtained classification accuracy of 100% in the best case and of around 99.8% on average. This is very promising compared to the previously reported results. This result is for Wisconsin Breast Cancer Dataset but it states that this method can be used confidently for other breast cancer diagnosis problems, too.

Supply Chain Management Practices, Competitive Advantages and Firm Performance： A Case of Small and Medium Enterprises （SMEs） in Vietnam

引用

Journal of Modern Accounting and Auditing 2018年第3期14卷 136-146页

作者： Duong Vu Xuan Quynh nguyen hoang Huy International University-Vietnam National University Ho Chi Minh City Vietnam

The perception of supply chain management （SCM） first appeared in 1982 and the very first papers on SCM were published in the mid 1980s （Houlihan, 1985）. However, this term is still fresh in Vietnam, especially the subject of SCM practices and their impacts on firm performance of small and medium enterprises （SMEs）. Therefore, the research was conducted to study the impact of supply chain management practices （SCMPs） on firm performance of SMEs through firm competitive advantages. Data were collected by surveying SMEs located in Ho Chi Minh City. The research findings showed that customer relationship （CR） and quality of information sharing （IQ） impact on firm performance at 0.01% significance level while the level of information sharing impacts on firm performance at 10% significance level, and strategic supplier partnership impacts on firm performance insignificantly. Moreover, we also found that customer relationship and quality of information sharing influence firm competitive advantage at 0.01% significance level, while strategic supplier partnership and the quality of information sharing impact on firm competitive advantage at 5% significance level. Competitive advantages impact significantly positively on firm performance at significance level of 0.001%. The findings imply that SMEs in Vietnam should manage customer relationship well and increase the level of information quality to improve competitive advantage in order to gain high performance.
