An Efficient and Effective Detailed Placement Algorithm Global Swap To identify a pair of cells that can be swapped to reduce wirelength (others are fixed). 2. Vertical Swap Swap a cell with a nearby cell in the segment above or below. 3. Local Re-ordering Re-order consecutive cells locally to reduce wirelength. 4. Single-Segment Clustering Place cells optimally within a segment.

在自然界中生物从其亲代继承特性或性状,这种现象称为遗传(Heredity),研究这种现象的科学叫遗传学(Genetics)。 在构成生物的细胞(Cell)中含有染色体(Chromosome),生物的遗传信息都包含在染色体中。遗传信息由基因(Gene)组成,基因是DNA(Deoxyribonucleic Acid)或RNA(Ribonucleic Acid)中占有一定位置的基本遗传单位。在DNA中遗传信息在长链上按照一定模式排列,即进行了遗传编码。遗传基因在染色体中占据的位置称为基因座(Locus),同一个基因座可能具有的全部基因称为等位基因(Allele),一个细胞核中所有染色体携带的遗传信息的全体称为基因组(Genome)。

Jakarta POI 是apache的子项目,目标是处理ole2对象。它提供了一组操纵Windows文档的Java API 目前比较成熟的是HSSF接口,处理MS Excel(97-2002)对象。它不象我们仅仅是用csv生成的没有格式的可以由Excel转换的东西,而是真正的Excel对象,你可以控制一些属性如sheet,cell等等。

A combined space鈥搕ime block coding (STBC) and eigen-space tracking (EST) scheme in multiple-input-multiple-output systems is proposed. It is proved that the STBC-EST is capable of shifting hardware complexity from the receiver to the transmitter without any bit error rate (BER) performance loss. A computation efficient EST algorithm is also proposed, which makes the STBC-EST affordable. Simulation results show that the STBC-EST with a modest feedback requirement results in a negligible BER performance loss compared with a dual system configuration.

The 2D CFD Program NaSt2D The program is a 2D solver for the incompressible, transient Navier-Stokes equations including the temperature equation and free boundary problems. It uses finite differences for discretization on a structured equidistant staggered grid, central and upwind (donor-cell) discretization of the convective parts and an explicit time stepping scheme. The free boundary value problems are treated with the MAC technique.
