压缩解压 本论文主要介绍了JPEG的编码和解码过程。该程序的编码部分能把一张BMP格式的图象进行JEPG编码
本论文主要介绍了JPEG的编码和解码过程。该程序的编码部分能把一张BMP格式的图象进行JEPG编码,压缩成以二进制形式保存的文件;通过相应的解码程序又可以把图象解压缩出来。在图象传送过程中,我们经常采用JPEG格式对静态图象进行编码。JPEG基本系统是一种有损编码,无法完全恢复出原图象,信息有一定的丢失,称为有损压缩 ...

序列对齐
Compare a protein sequence to a protein sequence
database or a DNA sequence to a DNA sequence database using the
Smith-Waterman algorithm.[.wat815.] \fCssearch3\fP is about 10-times
slower than FASTA3, but is more sensitive for full-length protein
sequence comparison.

This programme is to control DC motor in a certain speed using PWM.
The target speed is "r", it is the speed in 1s.
The sample rate is 0.1s, so the actual speed target is "rc"=r/10.
The "r" and "rc" are integer, and the range of "r" is from 50 to 100.
Keep rc=r/10!!!
The array "speed1" and "speed2" ...

Problem B:Longest Ordered Subsequence
A numeric sequence of ai is ordered if a1 < a2 < ... < aN. Let the subsequence of the given numeric sequence (a1, a2, ..., aN) be any sequence (ai1, ai2, ..., aiK), where 1 <= i1 < i2 < ... < iK <= N. For example, sequence (1, 7, 3, 5, 9, 4, 8) has ordered subse ...
