Solving velocity ratio of different mechanisms for equivalent models

2010 International Conference on Mechanic Automation and Control Engineering, 2010
Equivalent model is always used in single degree of freedom mechanism system, during analysis the dynamics or kinematics questions. Velocity ratio is the key question among the solving process. Three methods were introduced, based on the typical mechanism systems, such as linkage mechanism, gear mechanism and cam mechanism.

Testing for equivalence of variances using Hartley's ratio

Canadian Journal of Statistics, 2010
AbstractHartley's test for homogeneity of k normal‐distribution variances is based on the ratio between the maximum sample variance and the minimum sample variance. In this paper, the author uses the same statistic to test for equivalence of k variances.

The Influence of Dosimetry on Earlier Damage Equivalence Ratios

IEEE Transactions on Nuclear Science, 1975
Since it was first noted that the experimental damage equivalence ratios for different neutron spectra obtained from change in transistor parameter behavior did not agree with the calculated ratios based on damage to silicon, an explanation has been sought for this apparent discrepancy.
