Capacity-building programmes in Latin America

We review how capacity building in space sciences has developed in several Latin American countries, the state of development of some current programs and the role that space activities and space information play and can play in the future. We stress the need to educate educators, in order to increase the public awareness about the benefits of space research and, more importantly, attract the next generation of professionals that will be required in the coming decades.     

Toward a new cosmic consciousness: Psychoeducational aspects of contact with extraterrestrial civilizations

This study presents a new approach to the concept of cosmic consciousness integrated in current neuroscience knowledge and discusses implications for the search for extraterrestrial intelligence. It also examines different aspects related to consciousness and how it may play a key role in the understanding of the search for extraterrestrial intelligence and life in the Universe and its implications. Subjects (n=116) were college students from Spain, the United States, and Italy. Subjects responded to a questionnaire comprising five different sections: (A) religious beliefs, (B) environment and general opinion, (C) astronomy, (D) contact, and (E) attention and perception. The results showed the importance of several modular aspects that affect Space awareness in humans. Preliminary results are discussed with regard to current neuroscience, factor analysis, and possible implications for the understanding of contact with extraterrestrial intelligence. The roles of education, new search strategies, and possible contact scenarios are also discussed.     

转变法律教育观念培养合格法律人才

法律是科学的观念长期以来给法律教学模式带来深刻影响。当今社会发展，这种理念使法律教育弊端重重并与现实生活格格不入。法律非科学，法律是技术与艺术的结合，应当成为我们转变法律教育观念和法律教育模式改革的方向。

Shape preserving topology optimization for structural radar cross section control

The purpose of this paper is to present a shape preserving topology optimization method to prevent the adverse effects of the mechanical deformation on the Radar Cross Section(RCS).The optimization will suppress the variation of RCS on the perfect conductor surface by structural design. On the one hand, the physical optics method is utilized to calculate the structural RCS,which is based on the surface displacement field obtained from the finite element analysis of the structure. The correspondi...     

卫星多轴指向姿态控制全物理仿真实验研究

具有大型天线和大面积太阳帆板的多体卫星多轴指向控制技术是航天器控制的关键技术之一,针对这一问题,设计了“前馈+变结构”方案控制卫星本体,天线指向控制根据任务要求结合本体姿态产生,形成本体与天线多轴指向控制方案。基于常用的“飞轮—喷气”执行机构模式,考虑了控制精度和喷气消耗量问题。利用带有大型挠性板与程控天线系统的单轴气浮台物理仿真实验系统,成功地进行了卫星多轴指向控制物理仿真实验,本体姿态控制精度达到0.020,天线指向精度达到0.50。该研究对多轴指向卫星控制系统设计具有实际参考价值。     

挠性航天器振动抑制的自适应方法及实验研究

挠性航天器在平衡位置的小幅度振动对航天器的姿态控制精度具有严重影响,并且难以控制。现介绍了一种带有非线性阻尼器的自适应控制方法。该方法在黄金分割自适应控制方法的基础上,通过引入振动能量阻尼项得到了比较理想的振动抑制效果。该方法能够快速地抑制挠性航天器的低频振动,并且具有很好的过渡过程品质和稳态精度。文章最后通过物理仿真对比实验验证了这种方法的有效性。在相同条件下,其振动抑制的时间较传统方法减少了70％。此外,该控制方法对航天器的挠性振动频率的变化具有很好的适应能力。
