基于在线开放课程实践混合式教学模式的研究——以高职“报关业务”课程为例

近年来,受国家政策与信息时代潮流的影响,各高等院校纷纷建设与实施在线开放课程等信息化教学手段,混合式教学模式得以广泛流行。从高职院校“报关业务”课程建设在线开放课程的实践出发,讲述了在混合式教学模式探索方面的得失,认为此模式虽然没有解决所有问题,但注重个性化学习、能够调动学生的学习积极性,从而有效提升教学效果,是值得高职教师认真实践探索的教学模式。

Plasmonic evolution of atomically size-selected Au clusters by electron energy loss spectrum

The plasmonic response of gold clusters with atom number (N) = 100–70 000 was investigated using scanning transmission electron microscopy-electron energy loss spectroscopy. For decreasing N, the bulk plasmon remains unchanged above N = 887 but then disappears, while the surface plasmon firstly redshifts from 2.4 to 2.3 eV above N = 887 before blueshifting towards 2.6 eV down to N = 300, and finally splitting into three fine features. The surface plasmon''s excitation ratio is found to follow N^0.669, which is essentially R². An atomically precise evolution picture of plasmon physics is thus demonstrated according to three regimes: classical plasmon (N = 887–70 000), quantum confinement corrected plasmon (N = 300–887) and molecule related plasmon (N < 300).     

Finite-time consensus of neutrally stable multi-agent systems in the presence of input saturation

The problem of finite-time consensus of linear multi-agent systems subject to input saturation is investigated and two control protocols are presented for leaderless and leader-following cases, respectively. The leaderless multi-agent systems with proposed non-smooth protocol can achieve consensus in finite time. The consensus protocol designed for leader-following case with directed topology can solve the finite-time consensus problem, where a priori constraint is adopted to deal with input saturation. Furthermore, the settling time is explicitly derived using finite-time Lyapunov theory. Finally, the effectiveness of the theoretical results is illustrated with several numerical simulations.     

Fixed-time stabilization of general linear systems with input delay

In this paper, the fixed-time stabilization control problem for general linear systems with input delay is addressed. In addition to the Artstein–Kwon–Pearson reduction transformation, a pre-compensation control structure is established first to convert the original system into a single input delay-free linear system. Then, we show that the origin of the transformed system is fixed-time stabilizable by an additional homogeneous control design if the original system is controllable. Finally, an example is used to validate the proposed method via simulation results.

《寒夜》、《外套》主人公悲剧命运之比较

巴金先生是我国现代文学史上的巨匠,果戈理是俄国批判现实主义文学“自然派”的奠基人。巴金先生年青时就深受俄罗斯文学的影响,非常欣赏俄罗斯作家的创作风格。将巴金的《寒夜》与果戈理的《外套》相比较,两部作品有一定的相似之处。
