A New Involute Tooth Profile Measuring System with Special-Purpose Computer

A New Special-Purpose Factorization Algorithm

In this paper, a new factorization algorithm is presented, which finds a prime factor p of an integer n in time (D log n)O(1), if 4p − 1 = Db2 where D and b are integers. Hence this algorithm will factor a number efficiently, if it has a prime factor p such that 4p−1 is a product of a small integer and a square. Such primes should be avoided when we select the RSA secret keys. Some generalizati...

A special purpose computer for ab initio molecular dynamics simulations

A high performance system for molecular dynamics simulation of biomolecules using a special-purpose computer.

GRAPE (GRavity PipE) processors are special purpose computers for simulation of classical particles. The performance of MD-GRAPE, one of the GRAPEs developed for molecular dynamics, was investigated. The effective speed of MD-GRAPE was equivalent to approximately 6 Gflops. The precision of MD-GRAPE was good judging from the acceptable fluctuation of the total energy. Then a software named PEACH...

A New Statistical Model for Predicting Tooth Engagement and Load Sharing in Involute Splines

Load-sharing among the teeth of involute splines is little understood. Designers typically assume only a fraction of the teeth are engaged and distribute the load uniformly over the assumed number of engaged teeth. This procedure can widely overor underestimate tooth loads. A new statistical model for involute spline tooth engagement has been developed and presented earlier, which takes into ac...
