Product development process management plays an important role in concurrent engineering (CE). The integration platform is a useful tool for effectively supporting the software development and integration. Based on the analysis of practical requirements for product development process management for CE, a CORBA-based integration platform of product development process management (IP-PDPM) is designed and developed. The design principles for IP-PDPM are described. The system architecture and functions of the platform are given, the key technologies for the implementation of IP-PDPM are presented, the application integration mechanism and its implementation techniques are also detailed. 展开更多

为给某穿甲爆破(Armor-Piercing High-Explosive,APHE)弹优化设计提供参考,运用ANSYS/LS-DYNA对某小口径火炮穿甲爆破弹以不同着角、不同着速侵彻不同厚度均质钢靶板的过程进行仿真,得到弹丸穿靶过程中的速度变化规律以及穿靶后的形态... 为给某穿甲爆破(Armor-Piercing High-Explosive,APHE)弹优化设计提供参考,运用ANSYS/LS-DYNA对某小口径火炮穿甲爆破弹以不同着角、不同着速侵彻不同厚度均质钢靶板的过程进行仿真,得到弹丸穿靶过程中的速度变化规律以及穿靶后的形态、存速和剩余动能等.仿真结果表明:对弹体头部形状和尺寸进行优化设计可以提高弹丸的穿甲性能,其中将弹体头部改为截锥形,弹丸穿靶后剩余动能提高5.3%;弹体头部形状对弹丸穿甲强度也有影响,其中尖锥形最差,截锥形最优;随着着角的增大,弹丸剩余动能越来越小,当着角达到65°时会出现跳弹现象. 展开更多

When conducting a literature review,medical authors typically search for relevant keywords in bibliographic databases or on search engines like Google.After selecting the most pertinent article based on the title’s relevance and the abstract’s content,they download or purchase the article and cite it in their manuscript.Three major elements influence whether an article will be cited in future manuscripts:the keywords,the title,and the abstract.This indicates that these elements are the“key dissemination tools”for research papers.If these three elements are not determined judiciously by authors,it may adversely affect the manuscript’s retrievability,readability,and citation index,which can negatively impact both the author and the journal.In this article,we share our informed perspective on writing strategies to enhance the searchability and citation of medical articles.These strategies are adopted from the principles of search engine optimization,but they do not aim to cheat or manipulate the search engine.Instead,they adopt a reader-centric content writing methodology that targets well-researched keywords to the readers who are searching for them.Reputable journals,such as Nature and the British Medical Journal,emphasize“online searchability”in their author guidelines.We hope that this article will encourage medical authors to approach manuscript drafting from the perspective of“looking inside-out.”In other words,they should not only draft manuscripts around what they want to convey to fellow researchers but also integrate what the readers want to discover.It is a call-to-action to better understand and engage search engine algorithms,so they yield information in a desired and self-learning manner because the“Cloud”is the new stakeholder. 展开更多

Nonlinear solution of reinforced concrete structures, particularly complete load-deflection response, requires tracing of the equilibrium path and proper treatment of the limit and bifurcation points. In this regard, ordinary solution techniques lead to instability near the limit points and also have problems in case of snap-through and snap-back. Thus they fail to predict the complete load-displacement response. The arc-length method serves the purpose well in principle, received wide acceptance in finite element analysis, and has been used extensively. However modifications to the basic idea are vital to meet the particular needs of the analysis. This paper reviews some of the recent developments of the method in the last two decades, with particular emphasis on nonlinear finite element analysis of reinforced concrete structures. 展开更多
