The 2D CFD Program NaSt2D The program is a 2D solver for the incompressible, transient Navier-Stokes equations including the temperature equation and free boundary problems. It uses finite differences for discretization on a structured equidistant staggered grid, central and upwind (donor-cell) discretization of the convective parts and an explicit time stepping scheme. The free boundary value problems are treated with the MAC technique.

Playfair Cipher 1.not even the large number of keys in a monoalphabetic cipher provides security 2.one approach to improving security was to encrypt multiple letters 3.the Playfair Cipher is an example 4.invented by Charles Wheatstone in 1854,but named after his friend Baron Playfair Playfair Key Matrix 1.a 5X5 matrix of letters based on a keyword 2.fill in letters of keyword (sans duplicates) 3.fill rest of matrix with other letters Encrypting and Decrypting -plaintext is encrypted two letters at a time 1. if a pair is a repeated letter, insert filler like X’ 2. if both letters fall in the same row, replace each with letter to right (wrapping back to start from end) 3. if both letters fall in the same column, replace each with the letter below it (again wrapping to top from bottom) 4. otherwise each letter is replaced by the letter in the same row and in the column of the other letter of the pair

编写一个java应用程序。用户从键盘输入一个1-9999之间的数,程序将判断这个数是几位数,并判断这个数是否回文数。回文数是指将数含有的数字逆序排列后得到的数和原数相同,例如12121,4224,6778776等都是回文数。 1)程序具有判断用户的输入是否为合法整数的功能。对非法输入(例如含有字母)要进行处理。 2)要判断输入数的位数,并输出相关信息。 3)要判断是否回文数。 二、二战期间,英国情报人员获取德军的一机密电报,电报的内容为: bzdz izu sxgzd vs lh ,vpzg woflsh vs vwrh vhlsddlmp glm wrw gzy vsg .gflyz gstfzu bvsg gzsd hdmlp vml lm ,hghzvy wmz hwiry mvvdgvy izd z hzd vivsg ,ltz tmlo tmlO 情报人员已经知道,这段电报的加密方式为: 1. 首先将字符串的顺序颠倒。 2. 字母互换的规律为:A->Z, B-Y, C-X...X->C, Y->B, Z-A a->z, b->y, c-x...x->c, y->b, z->a. 3. 非字母字符保持不变。 请编程帮助情报人员破译这份机密电报。给出注释良好的源程序和程序运行后的结果。

This small utility helps to generate seven segment display codes for different I/O connections. For example, AVR/PIC Port A.0 -> D Segment Port A.1 -> B Segment .... Also it can generate Common Cathode or Common Anode table codes.. I Coded it long time ago. I Hope help someone. Thank you
