In each step the LZSS algorithm sends either a character or a <position, length> pair. Among these, perhaps character "e" appears more frequently than "x", and a <position, length> pair of length 3 might be commoner than one of length 18, say. Thus, if we encode the more frequent in fewer bits and the less frequent in more bits, the total length of the encoded text will be diminished. This consideration suggests that we use Huffman or arithmetic coding, preferably of adaptive kind, along with LZSS.
Securing Apache 2: Step-by-Step
When choosing a web server, Apache very often wins against its competitors because of stability, performance, that fact that it s open source, and many other advantages. But when deciding on which version of Apache to use, the choice is not always so simple. On the one hand there is a very popular, stable version used by millions of users, version 1.3, and on the other hand, there is an enhanced and re-designed version 2.0.
Some algorithms of variable step size LMS adaptive filtering are studied．The VS—LMS algorithm is improved．
Another new non-linear function between肛and e(／ t)is established．The theoretic analysis and computer
simulation results show that this algorithm converges more quickly than the origina1．Furthermore，better antinoise
property is exhibited under Low—SNR environment than the original one．
Ink Blotting
One method for escaping from a maze is via ‘ink-blotting’. In this method your starting square
is marked with the number ‘1’. All free, valid squares north, south, east and west around the
number ‘1‘ are marked with a number ‘2’. In the next step, all free, valid squares around the two
are marked with a ‘3’ and the process is repeated iteratively until :
The exit is found (a free square other than the starting position is reached on the very edge
of the maze), or,
No more free squares are available, and hence no exit is possible.
In just 24 lessons of one hour or less, you will be able to build dynamic Web sites using JavaServer Pages. Using a straightforward, step-by-step approach, each lesson builds on the previous ones, enabling you to learn the essentials of JavaServer Pages 2.0 from the ground up. The book includes Apache Tomcat, Sun s reference implementation of JSP, so you can start developing applications immediately.
Recognizing its importance is only the fist step to advocate invetion or innovation， and some effective measures should be taken for it. For one thing， our authority should continue to enlarge the recruit of graduate. For another， the conditions of scientists and skilled workers should be further improved. Only in this way， can “the soul of our nation” be fully embodied and our nation have a brighter future.
