The module LSQ is for unconstrained linear least-squares fitting. It is based upon Applied Statistics algorithm AS 274 (see comments at the start of the module). A planar-rotation algorithm is used to update the QR- factorization. This makes it suitable for updating regressions as more data become available. The module contains a test for singularities which is simpler and quicker than calculating the singular-value decomposition. An important feature of the algorithm is that it does not square the condition number. The matrix X X is not formed. Hence it is suitable for ill- conditioned problems, such as fitting polynomials. By taking advantage of the MODULE facility, it has been possible to remove many of the arguments to routines. Apart from the new function VARPRD, and a back-substitution routine BKSUB2 which it calls, the routines behave as in AS 274.

Linux 虚拟网络接口 实例 In the Linux (or Unix) world, most network interfaces, such as eth0 and ppp0, are associated with a physical device that is in charge of transmitting and receiving data packets. However, some logical network interfaces don t feature any physical packet transmission. The most well-known examples of these "virtual" interfaces are the shaper and eql interfaces.

This PNG Delphi version 1.56 documentation (this version is a major rewrite intended to replace the previous version, 1.2). Improvements in this new version includes: This new version allows the programmer to not use Delphi heavy units which will greatly reduce the size of the final executable. Read more about this feature here. Most, if not all, Portable Network Graphics features as CRC checking are now fully performed. Error on broken images are now better handled using new exception classes. The images may be saved using interlaced mode also. Transparency information won t be discarted after the image is loaded any more. Most of the images are decoded much faster now. The images will be better encoded using fresh new algorithms. IMPORTANT! Now transparency information is used to display images.

This model is just testing an idea of MIMO, which IEEE802.11n will have. But I havo not seen the standard, I tried to make it with 11a. Actually this model would not work in real world, because the preambles were not designed to solve the MIMO feature. But this model may be useful to get some idea to start to design a PHY with MIMO.

PCI-to-PCI Bridge Architecture Specification Revision 1.1 This specification establishes the requirements that a PCI-to-PCI bridge must meet to be compliant to this specification and the PCI Local Bus Specification. In addition, the requirements for optional extensions are specified. This specification does not describe the implementation details of any particular requirement or optional feature of a PCI-to-PCI bridge, nor is it a goal of this specification to describe any particular PCI-to-PCI bridge implementation. However, some recommendations are provided for some implementation-specific features that can be provided by a PCI-to-PCI bridge.

基于RSS的新闻阅读器 什么是RSS？比较普遍的说法有两种，一种是“Rich Site Summary”或“RDF Site Summary”，另一种是“Really Simple Syndication”，中文分别称作“丰富站点摘要”,“RDF站点摘要”和“简易信息聚合”。RSS是某一站点用来和其它站点之间共享和同步信息内容的一种简易方式。网络用户只要使用支持RSS的新闻聚合工具软件，就能在不打开某个网站页面的情况下阅读支持RSS输出的网站内容，并可以方便地实现对某类信息的全程跟踪、即时更新以及网上搜索。在不远的将来，RSS作为一种全新的资讯传播方式，势必对互联网上的信息接收与发布、新闻出版、电子商务、互动交流等领域产生难以估量的影响。 ++++++外文
