A few short years ago, the applications for video were somewhat confined—analog was used for broadcast and cable television, VCRs, set-top boxes, televisions and camcorders. Since then, there has been a tremendous and rapid conversion to digital video, mostly based on the MPEG-2 video compression standard. Today, in addition to the legacy DV, MPEG-1 and MPEG-2 audio and video com- pression standards, there are three new high- performance video compression standards. These new video codecs offer much higher video compression for a given level of video quality.

C 开发的有限元软件,界面还可以,不错,可以试试。 FElt is a free system for introductory level finite element analysis. It is primarily intended as a teaching tool for introductory type courses in finite elements - probably in the mechanical/structural/civil fields. In a command line environment, FElt uses an intuitive, straightforward input syntax to describe problems. It also includes a graphical user interface for workstations that allows the user to set-up, solve and post-process the problem in a single CAD-like environment.

MTOOLS version 2.0 Mtools is a public domain collection of programs to allow Unix systems to read, write, and manipulate files on an MSDOS filesystem (typically a diskette). The following MSDOS commands are emulated: Mtool MSDOS name equivalent Description ----- ---- ----------- mattrib ATTRIB change MSDOS file attribute flags mcd CD change MSDOS directory mcopy COPY copy MSDOS files to/from Unix mdel DEL/ERASE delete an MSDOS file mdir DIR display an MSDOS directory mformat FORMAT add MSDOS filesystem to a low-level format mlabel LABEL make an MSDOS volume label. mmd MD/MKDIR make an MSDOS subdirectory mrd RD/RMDIR remove an MSDOS subdirectory mread COPY low level read (copy) an MSDOS file to Unix mren REN/RENAME rename an existing MSDOS file mtype TYPE display contents of an MSDOS file mwrite COPY low level write (copy) a Unix file to MSDOS

This approach addresses two difficulties simultaneously: 1) the range limitation of mobile robot sensors and 2) the difficulty of detecting buildings in monocular aerial images. With the suggested method building outlines can be detected faster than the mobile robot can explore the area by itself, giving the robot an ability to “see” around corners. At the same time, the approach can compensate for the absence of elevation data in segmentation of aerial images. Our experiments demonstrate that ground-level semantic information (wall estimates) allows to focus the segmentation of the aerial image to find buildings and produce a ground-level semantic map that covers a larger area than can be built using the onboard sensors.

PRINCIPLE: The UVE algorithm detects and eliminates from a PLS model (including from 1 to A components) those variables that do not carry any relevant information to model Y. The criterion used to trace the un-informative variables is the reliability of the regression coefficients: c_j=mean(b_j)/std(b_j), obtained by jackknifing. The cutoff level, below which c_j is considered to be too small, indicating that the variable j should be removed, is estimated using a matrix of random variables.The predictive power of PLS models built on the retained variables only is evaluated over all 1-a dimensions =(yielding RMSECVnew).

fwknop stands for "Firewall Knock Operator" and is an upcoming piece of software that will be released at the DEFCON 12 conference in July, 2004 in Las Vegas. fwknop implements network access controls (via iptables) based on a flexible port knocking mini-language, but with a twist it combines port knocking and passive operating system fingerprinting to make it possible to do things like only allow, say, Linux-2.4/2.6 systems to connect to your SSH daemon. fwknop supports shared, multi-protocol port knock sequences along with both relative and absolute timeouts, and coded port knock sequences encrypted with the Rijndael block cipher.

MICROSOFT FOUNDATION CLASS LIBRARY : 学生管理系统 ======================================================================== AppWizard has created this 学生管理系统 application for you. This application not only demonstrates the basics of using the Microsoft Foundation classes but is also a starting point for writing your application. This file contains a summary of what you will find in each of the files that make up your 学生管理系统 application. 学生管理系统.dsp This file (the project file) contains information at the project level and is used to build a single project or subproject. Other users can share the project (.dsp) file, but they should export the makefiles locally.
