	Experimental study on formability of bulk metallic glass as mold for microstructure replication (EI CONFERENCE) 会议论文 OAI收割作者: Liu J.; Lin J.; Huang Y.; Liu J.; Liu J. 收藏 \| 浏览/下载：51/0 \| 提交时间：2013/03/25 La62Al14Cu12Ni12BMG is introduced as a substitute for silicon which was widely used as mold material for nanofabrication. For the purpose of precise microstructure replication and complete filling effects of various imprint parameters including imprint temperature imprint time and compression load on formability of La 62Al14Cu12Ni12BMG are studied and discussed. Scanning electron microscope images and results of thermal analysis are used to characterize the filling effect of La62Al 14Cu12Ni12BMG. In particular correlations between time and thermodynamic properties are presented. Despite of its high viscosity at crystallization temperature and its narrow supercooled liquid region La62Al14Cu12Ni12BMG is proved to be a durable and promising material which can precisely replicate the patterns of silicon mold and then transfer its own patterns on Ce 69Al10Cu20Co1BMG and PMMA. 2012 Elsevier B.V.

	A parallel algorithm for medical images registration based on B-splines (EI CONFERENCE) 会议论文 OAI收割 4th International Congress on Image and Signal Processing, CISP 2011, October 15, 2011 - October 17, 2011, Shanghai, China 作者: Zhang T. 收藏 \| 浏览/下载：26/0 \| 提交时间：2013/03/25 Cubic B-splines is widely applied in non-rigid registration because of its approximation performance and fast computational characteristics. However a small scale non-rigid deformation is needed to characterize by a large number of control points. Moreover an iterative optimization strategy of the non-rigid registration algorithm and the normalized mutual information (NMI) cost a great quantity calculation. So the process of the non-rigid registration is slowed by calculations of NMI in a iterative optimization strategy. In this paper a parallel optimization algorithm based on cubic B-splines functions is proposed to parallelize the optimization algorithm of the nonrigid registration and the calculations of normalize mutual information. In practice a fast algorithm of cubic B-splines is used and the control points are only distributed on the targets. Experiments show that the use of the fast algorithm and the parallel optimization strategy improves the non-rigid registration process of medical images. 2011 IEEE.
	Transmission properties of multiband fss based on fractal elements (EI CONFERENCE) 会议论文 OAI收割 2010 9th International Symposium on Antennas Propagation and EM Theory, ISAPE 2010, November 29, 2010 - December 2, 2010, Guangzhou, China 作者: Gao J. 收藏 \| 浏览/下载：25/0 \| 提交时间：2013/03/25 Self-similar fractal elements that has multiband properties can be advantageously exploited to design simple multiband FSS on single screen. In this paper fractal Y aperture FSS has been designed using recursive technology and the periodic method of moments(PMoM) is employed to characterize the transmission properties of FSS as band-pass filters. The frequency response to the structure parameters when electromagnetic wave incident with different angles and polarizations is discussed and the numerical analysis show good correlation to the measured results. 2010 IEEE.
