girth12rr
QC-LDPC码生成矩阵编程,围长为12,无4环(The program searches for a girth 12 QC-LDPC code given size of sub-matrix, row and column weights. The configuration of sub-matrices could also be changed. The program offers flexibility in constructing girth-12 QC-LDPC codes compared to other algorithms. The program builds a Tanner graph by connecting groups of rows and columns. A connection is made if it does not form less than twelve-cycles. The program may fail to find a code given particular parameters. It also does not find the smallest codes compared to other algorithms. )

Finite-Element---Using-MATLAB
介绍用matlab进行有限元计算的国外经典著作,前面重点介绍了有限元的相关内容,后面重点讲解了如何利用matlab的工具箱实现有限元的计算。(This book gives a background treatment of the Galerkin method in Chaps. 2–4.
Topics such as developing weak formulations as prelude to solving the finite
element equation, interpolation functions, derivation of elemental equations,
assembly and sample solutions were treated in these chapters. Chapter 5 gives an
overview on the use of the pdetoolbox. Chapter 6 and 7 give different sample
problems and their solutions on heat transfer and elasticity in Materials
Engineering.)

This paper presents a dual voltage source inverter
(DVSI) scheme to enhance the power quality and reliability of
the microgrid system. The proposed scheme is comprised of two
inverters, which enables the microgrid to exchange power generated
by the distributed energy resources (DERs) and also to
compensate the local unbalanced and nonlinear load. The control
algorithms are developed based on instantaneous symmetrical
component theory (ISCT) to operate DVSI in grid sharing and
grid injecting modes. The proposed scheme has increased reliability,
lower bandwidth requirement of the main inverter, lower
cost due to reduction in filter size, and better utilization of microgrid
power while using reduced dc-link voltage rating for the
main inverter. These features make the DVSI scheme a promising
option for microgrid supplying sensitive loads. The topology and
control algorithm are validated through extensive simulation and
experimental results.

This paper presents a new approach to image segmentation using Pillar K-means algorithm. This
segmentation method includes a new mechanism for grouping the elements of high resolution images in order to
improve accuracy and reduce the computation time. The system uses K-means for image segmentation optimized by
the algorithm after Pillar. The Pillar algorithm considers the placement of pillars should be located as far from each
other to resist the pressure distribution of a roof, as same as the number of centroids between the data distribution. This
algorithm is able to optimize the K-means clustering for image segmentation in the aspects of accuracy and
computation time. This algorithm distributes all initial centroids according to the maximum cumulative distance metric.
This paper evaluates the proposed approach for image segmentation by comparing with K-means clustering
algorithm and Gaussian mixture model and the participation of RGB, HSV, HSL and CIELAB color spaces.
