Description: VHDL 8位无符号除法器 试验报告
计算前在A和B端口输入被除数和除数，然后在Load线上送高电平，把数据存到除法计算电路内部，然后经过若干个时钟周期，计算出商和余数，并在C和D端输出。
其实现方法是，将除法器分为两个状态：等待状态与运算状态。
开始时除法器处于等待状态，在该状态，在每一时钟上升沿，采样Load信号线，若是低电平，则仍处于等待状态，如果采样到高电平，除法器读取A，B数据线上的输入数据，保存到内部寄存器a_r，b_r，置c_r为0，d_r为a_r，判断除数是否为零，若不为零则进入运算状态。
-VHDL eight unsigned divider calculation of the test report before the A and B ports to import and dividend divider, and then sent to I Load line, the data are uploaded to the internal division calculation circuit, and then after a number of clock cycles, and worked out more than a few, and in the C-and D output. Their method is to be divided into two division for the state : waiting for the state and Operational state. At the beginning divider waiting for the state, in the state in each clock rising edge, sampling Load signal line, if low-level, it is still waiting for the state, if the sampling to allow high output, Divider read A, B online data input data, preservation of the internal registers renovation r, b_r, home c_r 0, d_r a_r to determine whether the divisor zero, if not zero, it

Description: 这是一个JSP在线考试系统，后台数据库为MySQL。这是一个完整的web应用程序，实现了教师出题、学生在线考试(自由测试、单元测试、模拟考试)、错题本，以及相关的系统维护功能。在线测试的功能主要包括三部分：教师出题、学生在线考试和系统维护：系统维护包括对年级科目、知识点和模拟考试这些信息的维护，包括对相关内容的查看、添加和删除，并保持这些信息间的内部关联；教师试题录入模拟包括录入自由测试、单元测试、和模拟考试的试卷，并可以对系统中的试卷或试题进行修改； 学生在线考试模块包括自由测试、单元测试、模拟测试、考试成绩和错题本这些功能模块。 我目前已经完成了原型，基本程序在Windows 2000和Linux 7.2中，使用Tomcat 5.0进行了缜密的测试，目前可以良好地运行。但就功能来说还要进行更多的完善。-This is a JSP online exam system, the background database MySQL. This is a complete web applications, to achieve the title of teachers, students online exam (free testing, unit testing, mock examinations), the wrong title of this, as well as related maintenance functions

a b s t r a c t
In recent years artificial neural networks (ANNs) have been applied to many geotechnical engineering
problems with some degree of success. With respect to the design of pile foundations, accurate prediction
of pile settlement is necessary to ensure appropriate structural and serviceability performance.
