But we can do it using computer-generated holograms (CGH). The principle and design of the CGH have been discussed in the paper. Take the cubic suface as an example  The order separation of the CGH is analyzed theoretically and the simulation result of the order separation is given in the paper. We develop the binary process of the continuous CGH phase function and get the sample of the amplitude CGH. A CGH for testing a cubic phase plate with duty cycle 0.5 is fabricated by using e-beam lithographic techniques. In this situation  the contrast of the interference fringe pattern can achieve a level of 99.4% by calculation. 2012 IEEE.   Search for large extra dimensions in dimuon and dielectron events in pp collisions at root s=7 TeV 期刊论文  OAI收割 PHYSICS LETTERS B, 2012, 卷号: 711, 期号: 1, 页码: 15-34 作者:  CMS Collaboration 收藏  |  浏览/下载：351/0  |  提交时间：2015/12/02 FERMION-PAIR PRODUCTION  TO-LEADING ORDER  CONTACT INTERACTIONS  E(+)E(-) COLLISIONS  QCD CORRECTIONS  CROSS-SECTION  SCALE GRAVITY  LEP  HERA  DISTRIBUTIONS   Topography of funneled landscapes determines the thermodynamics and kinetics of protein folding 期刊论文  OAI收割 proceedings of the national academy of sciences of the united states of america, 2012, 卷号: 109, 期号: 39, 页码: 15763-15768 Wang J; Oliveira RJ; Chu XK; Whitford PC; Chahine J; Han W; Wang EK; Onuchic JN; Leite VBP 收藏  |  浏览/下载：25/0  |  提交时间：2013/10/09 ROUGH ENERGY LANDSCAPES  SINGLE-DOMAIN PROTEINS  TRANSITION-STATE  CONTACT ORDER  STATISTICAL-MECHANICS  STRUCTURE-PREDICTION  GLOBULAR-PROTEINS  MINIMAL MODELS  LATTICE MODELS  CHAIN-LENGTH   The parallel computation in one-way hash function designing (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China 作者:  Yang H. 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/25 In order to put the parallel one-way hash function into engineering  two designing models based on pipeline technology are proposed in this paper. The definition of one-way hash function is shown first  and the structure and limitation of the current hash functions are discussed afterward. By analyzing the difference between parallel computation on different platforms and classifying one-way hash functions on application basis  the possibility and method of parallel one-way hash function designing on different hardware platforms are described  two designing models are constructed for the parallel one-way hash function designing. Finally  some attentions for designing are proposed from the engineering angle. The pipeline models that proposed in this paper contact the theoretical rationality and the engineering application of parallel one-way hash function together  which can improve the practicality of parallel one-way hash function to a great extent. 2010 IEEE.   A real-time two-dimensional correlation speed measurement based on image (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China 作者:  Yu L. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 In order to implement two-dimensional moving object's non-contact and real-time speed measurement  in this paper  wc proposed a new method which was based on the characteristic of FPGA and a real-time two-dimensional correlation speed measurement was proposed on image processing using high speed CMOS shown in figure 1. Experimental installation was shown in figure 2  a cardboard with images which was fixed in electric control movement device was moving to simulate moving object  the CMOS image sensor gathered image signals of the cardboard and the image signals was output to FPGA after a serials pretreatment such as binaryzation etc. Logical operation insteaded mathematical operation on FPGA to implement two frames image's cross-correlation operations as the formula (10) in this paper  and finally calculate the two-dimensional velocity. Through experiment result of table 1 we drawn an conclusion the accurarcy of the method in this paper was less than 1 pixel and the method can be used at a certain speed ranges of two-dimensional  real-time speed measurement. 2010 IEEE.   Space optics remote sensor focusing components mechanics characteristic analysis based on FEM (EI CONFERENCE) 会议论文  OAI收割 International Symposium on Photoelectronic Detection and Imaging 2009: Material and Device Technology for Sensors, June 17, 2009 - June 19, 2009, Beijing, China 作者:  Wang B.;  Ren J.-Y.;  Wang B. 收藏  |  浏览/下载：159/0  |  提交时间：2013/03/25 Space optical remote sensor is very important in many fields of science and military significance. It is widely applied. Space optical remote sensor design and manufacturing require precision and stability. Focusing mechanics is an important component of remote sensors. Focusing mechanics can guarantee the stability of the entire mechanics focusing accuracy  therefore the stability of research focusing mechanics is very important. In order to guarantee the space optics remote sensor focusing mechanics the stability  takes steps the space optics remote sensor focusing organization mechanics characteristic analysis from the classics contact theory. This article uses international general non-linear finite element analysis software ABAQUS to carry on mechanics characteristic analysis to the space optics remote sensor focusing mechanics. First acts according to the focusing mechanics unique feature  carries on the finite element to the structural model the grid division  the material attribute disposition and the boundary condition indeed grades. Then establishment contact non-linear finite element model  and to focusing organization finite element model infliction unit action. Like this contacts the result and the equivalent static analysis result which the nonlinear analysis obtains carries on the contrast and the analysis. This article last count result modality is 90HZ  satisfies the space optics remote sensor structure overall modality to request to be bigger than 50HZ.This article when carries on the dynamic analysis  extracts the structure kinetic energy and the acceleration curve. In the dynamic analysis obtained transient response analysis modality 70.5Hz  this also is bigger than 50HZ. The dynamic analysis indicated the structure dynamic stability has the distinct enhancement  has provided certain foundation for the space optics remote sensor following development work  reduced the overall system development cycle. 2009 SPIE.   A high-speed acquisition and processing system of the laser speckle signal on the magnetic fluid (EI CONFERENCE) 会议论文  OAI收割 International Symposium on Photoelectronic Detection and Imaging 2009: Laser Sensing and Imaging, June 17, 2009 - June 19, 2009, Beijing, China 作者:  Sun Y.;  Sun Y.;  Wan Q.-H. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 In order to achieve the dynamical detection and real-time analysis of the movement status of the magnetic fluid  according to the difficulties of the detection of the magnetic fluid  established a high-speed acquisition and processing system of laser speckle signal on the magnetic fluid. First of all  the FPGA (EP2C8T144C8N) drived the linear array CCD(TCD1501D) to scan in the corresponding time sequence given by the computer  collected the laser speckle interferometric image in rapid change on the surface of the magnetic fluid  which followed the movement of the magnetic fluid  and the signal collected by CCD was converted into the digital data through the high-speed A/D convertor and stored into the internal buffer FIFO of the FPGA  whose width and depth were designed by the user as required. Then  the FPGA sent the digital signal of the laser speckle interferometric images into the computer through the USB2.0 highspeed differential bus  whose transmission rate can reach 480Mb/s in theory. Finally  the distribution of the laser speckle on the magnetic fluid was messy and random  which carried certain information about the surface of the magnetic fluid  based on the theories of the statistic correlation and the subdivision of images  analysing and processing the laser speckle interferometric images  indirectly got the movement status of the magnetic fluid under the electromagnetic field. The experimental results show that: the High Speed Acquisition and Processing System has the advantage of full-court  non-contact  non-invasive  high-precision and high reliability and so on. The detection resolution of high speed acquisition and processing system is superior to 1m and the sample rate is 3Msps  which basically meets the requirements of the magnetic fluid movement state detection. 2009 SPIE.   Three-dimensional numerical manifold method based on hexahedron element with full first-order cover function and its application in underground excavation 会议论文  OAI收割 Nagoya Univ, Nagoya, JAPAN, SEP 25-29, 2006 作者:  Zhang, Y.

In order to reduce the input and output connections to the arrays  we employ a matrix addressable architecture  in which all the pixels in each row are connected by a common metal line on the top of the window layer (top electrode) or at the base of substrate(bottom electrode). Decreasing the size of electrodes makes for minimizing the size of device. The optic and electric isolation and good ohmic contact are also helpful to obtain superior optical and electrical performance. We describe a procedure of fabrication of AlGalnP-based orange micro-LED by wet etching. The structure of devices is etched using both isotropic and anisotropic etchant. The pixel size is about 16um 20um  and there are 1000 818 pixels in the light emitting chip whose diagonal is 1-in.   Single-molecule dynamics reveals cooperative binding-folding in protein recognition 期刊论文  OAI收割 plos computational biology, 2006, 卷号: 2, 期号: 7, 页码: 842-852 Wang J; Lu Q; Lu HP 收藏  |  浏览/下载：21/0  |  提交时间：2010/08/17 TRANSITION-STATE ENSEMBLE  ALDRICH-SYNDROME PROTEIN  MONTE-CARLO SIMULATIONS  ENERGY LANDSCAPE  CONFORMATIONAL DYNAMICS  CONTACT ORDER  MECHANISM  CDC42  TOPOLOGY  FUNNELS
