Γ形框架对初始缺陷敏感性的非线性屈曲分析

结合工程实例,利用ANSYS有限元软件,对优化设计后的Γ形框架进行非线性屈曲分析。计算五种工况,得出重要结论:该种结构屈曲后性能不稳定,对初始缺陷敏感,跨中初始负位移有利于屈曲后承载力上升,跨中初始正位移导致屈曲后承载力急剧下降,在工程设计及安装施工中应予以足够的重视。     

Recent Advances in Application of Computer-Aided Drug Design in Anti-Influenza A Virus Drug Discovery

Influenza A is an acute respiratory infectious disease caused by the influenza A virus, which seriously threatens global human health and causes substantial economic losses every year. With the emergence of new viral strains, anti-influenza drugs remain the most effective treatment for influenza A. Research on traditional, innovative small-molecule drugs faces many challenges, while computer-aided drug design (CADD) offers opportunities for the rapid and effective development of innovative drugs. This literature review describes the general process of CADD, the viral proteins that play an essential role in the life cycle of the influenza A virus and can be used as therapeutic targets for anti-influenza drugs, and examples of drug screening of viral target proteins by applying the CADD approach. Finally, the main limitations of current CADD strategies in anti-influenza drug discovery and the field’s future directions are discussed.     

基于有限样本的大气偏振模式生成方法

大气偏振模式在导航等领域具有广阔的应用前景,但是由于受到大气偏振信息采集装置物理特性的限制,在同一时刻只能获得局部的、不连续的偏振信息,对实际应用产生影响。针对此问题,本文通过挖掘大气偏振模式分布的连续性,提出一种大气偏振模式生成方法,从局部的偏振信息生成全天域的大气偏振模式。此外,偏振信息往往受到不同的天气条件、地理环境等因素的影响,而这些偏振数据在真实环境中难以采集。针对此问题,本文挖掘不同天气、地理条件下有限样本数据之间的多样性关系,以此关系将生成的大气偏振模式泛化到不同的条件下。本论文在仿真数据和实测数据上进行了实验,并与其它最新方法进行对比,实验结果证明了本文方法的优越性和鲁棒性。

提高水旱灾害防御能力 为汉川跨越式发展提供有力保障

湖北省汉川市地处江汉平原腹地,有长江最大支流汉江横贯全境,是一个襟江带湖的平原水网地区;境内地势低洼,河渠纵横,素有＂水袋子＂和＂千里汉江,险在汉川＂之称,是一个洪涝灾害频发的地方。     

An Information Hiding Algorithm Based on Bitmap Resource of Portable Executable File

An information hiding algorithm is proposed, which hides information by embedding secret data into the palette of bitmap resources of portable executable （PE） files. This algorithm has higher security than some traditional ones because of integrating secret data and bitmap resources together. Through analyzing the principle of bitmap resources parsing in an operating system and the layer of resource data in PE files, a safe and useful solution is presented to solve two problems that bitmap resources are incorrectly analyzed and other resources data are confused in the process of data embedding. The feasibility and effectiveness of the proposed algorithm are confirmed through computer experiments.
