This toolbox contains Matlab code for several graph and mesh Partitioning methods, including geometric, spectral, geometric spectral, and coordinate bisection. It also has routines to generate recursive multiway partitions, vertex separators, and nested dissection orderings and it has some sample meshes and mesh generators. The toolbox contains a Matlab interface to Leland and Hendrickson s Chaco Partitioning package, but it doesn t contain Chaco itself. The file "chaco/README" tells how to install the interface to Chaco. It also contains a Matlab interface to Karypis et al. s Metis Partitioning package, using Robert Bridson s "metismex" code.

cskmeans 聚类算法的一种 1. 分裂法(Partitioning methods)：给定一个有N个元组或者纪录的数据集，分裂法将构造K个分组，每一个分组就代表一个聚类，K<N。而且这K个分组满足下列条件：（1） 每一个分组至少包含一个数据纪录；（2）每一个数据纪录属于且仅属于一个分组（注意：这个要求在某些模糊聚类算法中可以放宽）；对于给定的K，算法首先给出一个初始的分组方法，以后通过反复迭代的方法改变分组，使得每一次改进之后的分组方案都较前一次好，而所谓好的标准就是：同一分组中的记录越近越好，而不同分组中的纪录越远越好。使用这个基本思想的算法有：K-MEANS算法、K-MEDOIDS算法、CLARANS算法；

遥感图像在人类生活和军事领域的应用日益广泛，适合各种要求的遥感图像编码技术具有重要的现实意义。基于小波变换的内嵌编码技术已成为当前静止图像编码领域的主流，其中就包括基于分层树集合分割排序(Set Partitioning inHierarchical Trees，SPIHT)的内嵌编码算法。这种算法具有码流可随机获取以及良好的恢复图像质量等特性，因此成为实际应用中首选算法。随着对图像编码技术需求的不断增长，尤其是在军事应用领域如卫星侦察等方面，这种编码算法亟待转换为可应用的硬件编码器。 在静止图像编码领域，高性能的图像编码器设计一直是相关研究人员不懈追求的目标。本文针对静止图像编码器的设计作了深入研究，并致力于高性能的图像编码算法实现结构的研究，提出了具有创新性的降低计算量、存储量，提高压缩性能的算法实现结构，并成功应用于图像编码硬件系统中。这个方案还支持压缩比在线可调，即在不改变硬件框架的条件下可按用户要求实现16倍到2倍的压缩，以适应不同的应用需求。本文所做的工作包括了两个部分。 1．一种基于行的实时提升小波变换实现结构：该结构同时处理行变换和列变换，并且在图像边界采用对称扩展输出边界数据，使得图像小波变换时间与传统的小波变换相比提高了将近2.6倍，提高了硬件系统的实时性。该结构还合理地利用和调度内部缓冲器，不需要外部缓冲器，大大降低了硬件系统对存储器的要求。 2．一种采用左遍历的比特平面并行SPIHT编码结构：在该编码结构中，空间定位生成树采用深度优先遍历方式，比特平面同时处理极大地提高了编码速度。

The LTC3546 is a dual output current mode buck regulatorwith fl exible output current Partitioning. Beyondthe advantages normally associated with dual outputregulators (reduced size, cost, EMI and part count, withimproved effi ciency), the LTC3546’s outputs can bepartitioned for either 3A and 1A outputs, or two 2A outputs.This increases its application range and simplifi esmultiple supply rail designs. A confi gurable Burst Mode®clamp for each output sets the current transition levelbetween Burst Mode operation and forced continuousconduction mode to optimize effi ciency over the entireoutput range. An adjustable switching frequency up to4MHz and internal power MOSFET switches allow forsmall and compact footprints.
