Convergence of a Force-Based Hybrid Method in Three Dimension
Convergence a Force-Based Hybrid Method Three Dimension
2012/8/7
We study a force-based hybrid method that couples atomistic model with Cauchy-Born elasticity model. We show the proposed scheme converges to the solution of the atomistic model with second order accu...
Incubation-time Based Approach for Dynamic Yielding of Metals
dynamic yielding incubation-time approach failure criteria
2012/9/24
Transition of the materials from elastic to plastic state is modeled by incubation-time based criterion. This approach is similar to the structural -temporal theory for brittle solids fracture develop...
Radon-based ULM 图像方向检测算法研究
Radon 变换 点扩展函数 最大类间差法 快速傅里叶变换
2012/9/24
通过分析以往算法的优劣,提出了基于 Radon 变换的匀速直线运动图像方向检测算法.首先指出匀速直线运动假设的合理性,推理该运动模式下图像的频谱特征;其次对经过预处理的图像应用Radon 变换,并计算出运动方向.实验结果表明:为更准确地确定运动方向而过分地缩短步长,将使运算代价变大,而效果较小.
Fourier transform based iterative method for x-ray differential phase-contrast computed tomography
X-ray phase-contrast tomography, x-ray refractive index, iterative reconstruction,interior tomography
2011/9/6
Biological soft tissues encountered in clinical and pre-clinical imaging mainly consist of light element atoms, and their composition is nearly uniform with little density variation. Thus,x-ray attenu...
Further Argument Against the Motion of the Earth, Based on Telescopic Observations of the Stars: An English Rendition of Chapter 30, Book 9, Section 4, Pages 460-463 of the Almagestum Novum Volume II of G. B. Riccioli
Further Argument Against Physics
2010/11/16
The Italian Jesuit astronomer Giovanni Battista (Giambattista) Riccioli constructed a powerful, thoroughly scientific argument in favor of geocentrism - an argument based on telescopic observations o...
Key Distribution based on Three Player Quantum Games
Three-Player Quantum Game Quantum Key Distribution
2010/11/4
We study a new QKD that is different from the scheme proposed by \cite{Ramz2}, though it essentially takes our ground on three-player quantum games and Greenberg-Horne-Zeilinger triplet entangled sta...
CGS Based Solar Cells with In2S 3 Buffer Layer Deposited by CBD and Coevaporation
Buffer layer In2S3 CBD chalcopyrite structural properties Solar cell
2010/6/30
In this paper we investigated In2S3 as substitute for CdS, which is conventionally used as buffer layer in chalcopyrite based solar cells. In2S3 thin films were deposited by CBD and co-evaporation met...
Statistical properties of agent-based models in markets with continuous double auction mechanism
Econophysics Financial stylized facts Agent-based simulation Complex networks Continuous double action
2010/4/27
Real world markets display power-law features in variables such as price fluctuations in stocks. To further understand market behavior, we have conducted a series of market experiments on our web-base...
Functional-Integral Based Perturbation Theory for the Malthus-Verhulst Process
Birth-and-death process Master equation Path integral Omega-expansion Doi formalism
2010/10/13
We apply a functional-integral formalism for Markovian birth and death processes to determine asymptotic corrections to mean-field theory in the Malthus-Verhulst process (MVP). Expanding about the sta...
Surface Characterization of Titanium Based Dental Implants
Titanium implants Dental implants Surface morphology
2010/9/29
The study of dental implant surfaces is relevant in order to better understand the interaction of the titanium
surface and the surrounding tissues. Clinical success is achieved not only because of im...
Contribution of the Charge Image Potential to Carrier Confinement in Graded Si-Based Quantum Wells
the Charge Image Potential Carrier Confinement Graded Si-Based Quantum Wells
2010/10/22
In order to analyze the charging effects on electronic spectrum of Silicon (Si) based quantum wells (QW’s), we use a method based on the calculation of the image charge potential by solving Poisson eq...

Photovoltaic Devices Photo Induced Charge Transfer Polythiophene CN-PPV Blends
2010/10/28
We have investigated the photovoltaic properties of polymer devices based on a blend of two polymers, (poly(3-(2’-methoxy-5’-octylphenyl) thiophene) (POMeOPT) and poly(2,5,2’,5’-tetrahexyloxy-7,8’-dic...
