这是一个考试系统，主要实现的题目有单项选择题，多项选择题和判断题。 1.对于每个题都是每次运行本软件的时候自动从题库中随机抽取。 2.在data文件夹下有一个配制文件： a.它可以修改每个类型的题目的数量。 b.它可以修改第个题目的分值。 c.它可以修改考试的限定时间。 3.在交卷后就可以查看，本次考试的得分。并根据本次考试满分的60％做为标准，来判断你是否通过这次考试。 4.后台是一个Access数据库，就可以加入新的题目。并不需要修改原程序。 判断题的表是judge,单选是single,多选是moresingle表， 5.在Access中可以添加新的考试人员。只要添加student表中的信息就可以了。 6.在每次交卷后的成绩，会重新保存到数据库中。 7.每次交卷后，都可以把这次所做的题目导出，包括答案和学生所做的答案，以及这次考试的得分。 8.在没有交卷前，做完的题目可以再次进行修改。 9.显示现在时间 吉林农业科技学院 06计算机科学与技术一班 幽居古藤

A paper that I presented on Supervisory Control and Data Acquisition (SCADA) won the second prize at the symposium conducted by the Electrical and Electronics Engineering department of the SRM University. Other topics on which I presented papers were Performance enhancement of wireless sensor networks using directional antennas, Smart card application and wireless communication. Also my research idea titled “Wavelet Based Image Compression Using SPIHT Algorithm “secured third prize in a technical festival.

Compression using lempel-ziv -for a dictionary size of 2k -provide dictionary Lempel ziv algorithm is a dictionary based algorithm that addresses byte sequences from former contents instead of the original data. This algorithm consists of a rule for parsing strings of symbols from a finite alphabet into substrings, whose lengths do not exceed a prescribed integer and a coding scheme which maps these substrings sequentially into uniquely decipherable code words of fixed length. The strings are selected so that they have nearly equal probability of occurrence. Frequently-occurring symbols are grouped into longer strings while occasional symbols appear in short strings.
