Description: This project requires you to write a program that imitates a simple desk calculator. Your calculator must be able to accept an infix expression which at least includes (, ), +, -, *, /, ％, and ^ (exponentiation operator, a^b = ab ). If the expression is legal, output its value, else output an error message.
Input Specification:
Your program must read test cases from a file “input.txt”. In the file there are several test cases, each occupies one line that contains an infix expression. Proceed until the end of the file.
Output Specification:
For each test case, output to a file “output.txt” in one line the value of that expression (accurate up to two decimal places), or an error message “ERROR IN INFIX NOTATION”.

Description: (繁体中文版)台湾出品不得多得的关于spa dpa 旁道攻击rsa算法的精彩论文。相对国内的一些翻译性质的、粗制滥造的论文，简直是一个天上一个地下。-As information technology has developed rapidly, it provides more convenient life for people. As the result, the security has become the main concern. Recently, user id and password are major methods to protect private information. However, the short password can be broken by hackers. Too long is not easy to memorize. Network traffic-analyzing tool provides the function to gain the user id and password while doing transaction via network. Therefore, low cost Smart Card including user name identification and cryptosystem algorithm has become new trend of
modern society.
The first object of this thesis is to present the design and implementati- on of a 512-bit RSA cryptosystem by using 8051 microcontroller. In RSA cryptosystem algorithm, modular exponentiation is the essential arithmetic operation. However, 8051 microcontroller does not provide the modular exponentiation. In order to complete RSA cryptosystem, this thesis has mentioned that using L-algorithm to transfer to modular mult Platform: |

Description: Understand and apply exponentiation-Wind chill is the apparent temperature felt by exposed skin on a cold, windy day. Normally, there is a thin layer of warm air
surrounding our bodies, and this warm air helps insulate us from the cold air around us. A strong wind reduces the amount
of insulation by this air layer, so our skin loses heat at a faster rate than it would otherwise. Our skin feels colder, which
makes us feel colder the temperature it "feels like" is the wind chill temperature. For example, if you re exposed to 30°F
air moving at 20 mph, your skin loses heat at the same rate it would in calm 17.4°F air, so the windchill is 17.4°F.
In 2001, the National Weather Service changed the formula used to calculate the wind chill index (the old formula
produced temperatures that were too low). The new formula is:
Wind Chill (in °F) = 35.74+ 0.6215 T- 35.75 (V0.16)+ 0.4275 T (V0.16)
where T is the air temperature in °F and V is the wind velocity in mph. (In case your browser has trouble showing it, V0.16

Description: 这是本人做的关于基于二叉树求算术表达式求值的课程设计，供大家一起学习。表达式求解问题
设计一个程序实现基于二叉树表示的算术表达式的操作。
1、 需求分析
1. 算术表达式的合法输入数据包括变量（A~Z,a~z）、常量（0－9）和二元运算符（＋，－，＊，／，^（乘幂））。程序对数据输入格式不作要求，用户需自己保证语法正确，详见用户手册说明。
2. 演示程序以人机对话的方式执行，即在计算机上显示提示信息后，由用户在键盘上输入对应的数据或命令，程序将执行相应的操作并显示下一步信息。
3. 程序执行的命令包括：
1)根据用户输入的前缀表达式自动添加括号并建立其自然书写形式的表达式；
2）提示用户给各变量赋值；
3）建立二叉树，并基于二叉树进行求值运算，显示结果。
4. 测试数据
分别输入0 a -91 +a*bc +*5^x2*8x +++*3^x3*2^x2x6并输出结果。
每当输入一个表达式后，程序提示用户赋值，再对表达式求值。
