  • Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux Main Features:

    Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux Main Features: * Creates a virtual encrypted disk within a file and mounts it as a real disk. * Encrypts an entire partition or storage device such as USB flash drive or hard drive. * Encrypts a partition or drive where Windows is installed (pre-boot authentication). * Encryption is automatic, real-time (on-the-fly) and transparent. * Provides two levels of plausible deniability, in case an adversary forces you to reveal the password: 1) Hidden volume (steganography) and hidden operating system. 2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data). * Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS. Further information regarding features of the software may be found in the:http://www.truecrypt.org/

    This is a program that I wrote many years ago. It is a floppy disk , disk copy,disk info,and format program. All written in masm assembler. There is also a small 252 byte driver that allows nonstandard floppy formats on dos systems below 7.0. Floppies can be formatted in any track and sector layout. 1.44M floppies can be formatted to 1.76 M. All source code,includes and libraries are included. Modify the bld.bat file to your own needs. There are many asm tricks in the source code. Have fun with this old code.

  • This paper analyzes the vector control theory of asynchronous motors based on the magnetic orientati

    This paper analyzes the vector control theory of asynchronous motors based on the magnetic orientation of motor rotors, and its mathematical model is made. Then the variable frequency vector speed-adjusting experimental system is built with the DSP TMS320F2812 which works as the core control chip and intelligent power module.
