摘要：随着电推进技术的不断成熟和持续应用,电推进以其高比冲优势正在成为深空探测任务的空间推进优选。其中,离子和Hall推力器作为主推进装置,已得到广泛应用。作为离子和Hall推力器的核心部件,空心阴极羽流等离子体放电不稳定引发的高能离子溅射,加剧了其腐蚀失效及性能恶化,最终导致推力器无法正常点火工作。因此,为了保证电推力器具备长寿命和高可靠性能,深入研究了空心阴极的稳态放电特性以及羽流振荡特性,归纳分析了主要影响因素,通过调节阴极组件设计参数、放电参数和供气模式及磁场位形等因素,可有效规避羽流振荡现象,减缓阴极组件的溅射腐蚀问题,延长阴极工作寿命,确保推力器能够长寿命、高可靠地稳定运行。

摘要：Nowadays, the development of cloud computing has given power to the resource-constrained network control system （NCS） to out-source heavy computations to the cloud server. However, the development of Cloud Computing produced many security challenges regarding the cyber-physical connection between the cloud and control system. The connection between the control system and cloud server can be subjected to distributed denial of service （DDoS） attack by an attacker to destabilize the NCS. In this paper, we will address this issue by building a secure mechanism for such systems. We will design a detection approach and a mitigation approach for better stable performance of NCS. To ensure the stability of NCS at the time of DDoS attack, we will also design a switching mechanism （SM） for cloud control system （CCS） when there are no more real time solutions available from the cloud. Finally, we will apply the proposed mechanism to an unmanned arial vehicle （UAV）. Our simulation results show that the mechanism works well in stability and protection of NCS under DDoS attack.

摘要：Smart morphing wing, which is equipped with smart materials and able to change structural geometry adaptively, can further improve aerodynamic efficiency of aircraft. This paper presents a new integrated layout and topology optimization design for morphing wing driven by shape memory alloys(SMAs). By simultaneously optimizing the layout of smart actuators and topology of wing substrate, the ultimately determined configuration can achieve smooth, continuous and accurate geometric shape changes. In addition, aerodynamic analysis is carried out to compare smart morphing wing with traditional hinged airfoil. Finally, the optimized smart wing structure is constructed and tested to demonstrate and verify the morphing functionality. Application setbacks are also pointed out for further investigation.

摘要：In this paper, the problems of chaos and chaos control for a class of susceptible-infected- removed （SIR） epidemic model with seasonal fluctuation are investigated. The season- ality in outbreak is natural among infectious diseases, as the common influenza, A type H1N1 influenza and so on. It is shown that there exist chaotic phenomena in the epidemic model. Furthermore, the tracking control method is used to control chaotic motions in the epidemic model. A feedback controller is designed to achieve tracking of an ideal out- put. Thus, the density of infected individuals can converge to zero, in other words, thedisease can be disappeared. Finally, numerical simulations illustrate that the controller is effective.

摘要：Six plant MARs isolated from tobacco and Arabdiposis were investigated for their ARS activity in yeast. The results showed that among the six plant MARs, only TM1 and AM4 had strong ARS activity which was almost the same as that of ARS from yeast chromosome. In order to further identify the core region of the two MARs for the ARS activity, a series of subclones were created by PCR strategy, and the corresponding subclones were designated as TM1-1, TM1-2, TM1-3, AM4-1, AM4-2 and AM4-3, respectively. Our studies revealed that TMI-3 and AM4-3 not only had higher ARS activity, but also displayed higher transformation frequency, plasmid stability and growth rate compared to their intact MARs, TM1 and AM4. These data present an important clue for further elucidating the relationship between MAR and ARS.
