This paper presents a new non-linear formulation of the classical Vortex Lattice Method （VLM） approach for calculating the aerodynamic properties of lifting surfaces. The method accounts for the effects of viscosity, and due to its low computational cost, it represents a very good tool to perform rapid and accurate wing design and optimization procedures. The mathematical model is constructed by using two-dimensional viscous analyses of the wing span-wise sections, according to strip theory, and then coupling the strip viscous forces with the forces generated by the vortex rings distributed on the wing camber surface, calculated with a fully three-dimensional vortex lifting law. The numerical results obtained with the proposed method are validated with experimental data and show good agreement in predicting both the lift and pitching moment, as well as in predicting the wing drag. The method is applied to modifying the wing of an Unmanned Aerial System to increase its aerodynamic efficiency and to calculate the drag reductions obtained by an upper surface morphing technique for an adaptable regional aircraft wing.

One of the difficulties in creating a blood substitute on the basis of human haemoglobin(Hb) is the toxic nature of Hb when it is outside the safe environment of the red blood *** plasma protein haptoglobin(Hp) takes care of the Hb physiologically leaked into the plasma-it binds Hb and makes it much less toxic while retaining the Hb’s high oxygen transporting *** used Electron Paramagnetic Resonance(EPR) spectroscopy to show that the protein bound radical induced by H2O2 in Hb and Hp-Hb complex is formed on the same tyrosine residue(s),but,in the complex,the radical is found in a more hydrophobic environment and decays slower than in unbound Hb,thus mitigating its oxidative *** data obtained in this study might set new directions in engineering blood substitutes for transfusion that would have the oxygen transporting efficiency typical of Hb,but which would be non-toxic.

随着电动自行车用户及行人数量的增加,行人和电动自行车用户的安全受到广泛关注。由于该类出行者与机动车共用道路,容易诱发交通事故,导致出行者遭受严重伤害,此类伤害程度远高于机动车与机动车之间的碰撞。因此有必要针对影响行人交通事故的因素开展深入研究,以降低或消除该类交通事故的发生,保障出行安全。本文基于湖南省2014年至2016年发生的8172交通的事故数据,筛选影响事故的主要因素,包括车辆违规驾驶行为(闯红灯,超度、疲劳、逆向和酒驾等;行人违规(行人在机动车道上行走)和环境因素(能见度,照明条件和事故发生的时间等),研究分析影响骑行者的伤害严重性和撞车事故中行人受伤的核心因素。主要研究内容及结论主要包括以下两个方面:(1)结合K-Means聚类分析法和多项式Logistic回归模型(MNLR)方法,解析事故因素对死亡,重伤和轻伤三种不同行人碰撞伤害严重程度的影响。研究结果表明:驾驶员的疲劳、酒驾、闯红灯、逆向违规驾驶行为、行人在车道上行走,能见度,行人年龄(65岁以上),天气条件和道路类型对行人的伤害严重程度具有显著影响。(2)提出了分类树和逻辑回归模型的组合方法,以获取不同群体的电动自行车驾手遭受严重伤害的潜在风险因素。回归树分析研究表明,城市地区55岁以上的非职业驾驶员遭受严重伤害的可能性更高;回归分析结果表明,高度道路等危险因素对不同组的伤害具有显著影响,而主要因素仅对特定组具有显著影响。
