Description: The purpose of this paper is to address the following problem: How can
existing sequential simulators be utilized in developing parallel simulators
for the numerical solution of partial di erential equations (PDEs)? We dis-
cuss this issue in the light of object-oriented (OO) programming techniques,
which can substantially increase the eciency of implementing parallel PDE
software. Our parallelization approach is to use domain decomposition (DD)
as an overall numerical strategy.

Description: The use of computational methods for solving partial differential equations in the field of Heat Transfer is crucial. However, the actual user friendly commercial applications, for the resolution of this kind of problems are expensive.
The purpose of this work is the development of a graphical interface for the resolution of heat
transfer problems using the finite volume method. This development is made in MATLAB, due
to its capacity to generate graphical results in an easy and efficient way.
This graphical interface is used as a learning tool in post graduation studies at University of
Minho.

Description: Matlab电磁波FDTD传输程序
模拟一天线发射电磁波在不同介质中的传播。-The Finite-difference time-domain (FDTD) method belongs in the general class of grid-based differential time-domain numerical modeling methods. The time-dependent Maxwell s equations (in partial differential form) are discretized using central-difference approximations to the space and time partial derivatives. The resulting finite-difference equations are solved in either software or hardware in a leapfrog manner: the electric field vector components in a volume of space are solved at a given instant in time then the magnetic field vector components in the same spatial volume are solved at the next instant in time and the process is repeated over and over again until the desired transient or steady-state electromagnetic field behavior is fully evolved.

Description: 在基于视觉检测方式的泊位自动引导系统中,从序列图像中提取泊位飞机,检测泊位飞机的阴影区域,是泊位系统实现的关键。基于高斯混合模型的背景分割算法被广泛应用于静态背景分割中,但是该算法在处理高分辨率图像时,算法实时性显著下降 分割体积大而且运动缓慢的物体时,容易产生“拖尾”现象 不能检测出运动物体的阴影区域。为此提出了基于分层图像的改进高斯混合模型背景分割算法,有效地克服了算法实时性差和“拖尾”现象。在此基础上,提出了基于色彩特征和区域特征相结合的阴影检测算法,利用部分空间约束信息,检测出运动物体的阴影区域。实验结果表明了该算法的有效性和实用性。

Description: 基于交叉累计剩余熵的图像配准中插值方法的改进
交叉累计剩余熵（CCRE）比传统互信息在配准强噪声图像时更具优势,但采用部分体积（PV）插值的CCRE在网格点容易产生局部极值,不利于变换参数的优化。针对该问题,研究基于3阶B样条函数的PV插值（BPV）、哈宁窗sinc函数的PV插值（HPV）和Blackman-Harris窗sinc函数的PV插值（BHPV）方法在CCRE中的应用,提出一种新的插值方法。该方法采用灵活的邻域中心,将插值点对联合直方图贡献的权重分散到临近的9个点上,并使用高斯函数作为PV插值的核函数,避免权重突变。实验结果表明,与BPV,HPV和BHPV插值方法相比,

To solve this problem, based on 3-order B-spline interpolation function PV (BPV), Hanning window sinc interpolation function PV (HPV) and Blackman-Harris window sinc interpolation function PV (BHPV) Application of CCRE, a new interpolation method. The method uses a flexible center of the neighborhood, the interpolation point joint histogram contribution weights dispersed to nine points nearby and use the Gaussian function as a PV interpolation kernel function, avoid weight changes.
