Two-degree-of-freedom (2-DOF) compliant mechanism has some outstanding characteristics in accurate positioning systems. Studying the fatigue life for 2-DOF is a meaningful task to ensure long working. However, study prediction of this not been conducted so far. In article, method developed first time. This combining differential evolution algorithm and adaptive neuro-fuzzy inference system (ANF...

We describe a distributed computing platform to lead large scale dictionary attacks against cryptosystems compliant to OpenPGP standard. Moreover, we describe a simplified mechanism to quickly test passphrases that might protect a specified private key. Only passphrases that pass this test complete the full (much more time consuming) validation procedure. This approach greatly reduces the time ...

The purpose of this research was to demonstrate the feasibility for creating a threedimensional monolithic compliant six-axis nanopositioner. Much of this work was based off of the original two-dimensional HexFlex manipulator created by Prof. Martin Culpepper and a three-dimensional design by Samuel Korb. The compliant mechanism was manufactured from a single sheet of 1/8 inch 5052 Aluminum. Th...

Abstract This work addresses the design of miniature compliant displacement amplifiers. The optimum mechanism is generated through topology optimization two-node frame elements with linearly varying cross sections using Ant Colony Optimization technique. First, stiffness matrices that account for change in cross-section dimensions are formulated. Then, each element assigned 5 independent ants r...
