A new approach to tolerance analysis based on tracking local coordinate systems
Among current approaches to tolerance analysis in three-dimensional space, the Matrix method based on rigid body kinematics is widely used. However, this method ignores the impact a tolerance feature (TF) may get from the variations of TFs before it ...

PDF reweighting in the Hessian matrix approach [PDF]
We introduce the Hessian reweighting of parton distribution functions (PDFs). Similarly to the better-known Bayesian methods, its purpose is to address the compatibility of new data and the quantitative modifications they induce within an existing set of

Performance Analysis of Multiple Antennas Synthetic False Target Jamming
The radar jamming technology has been studied in this paper mainly, which uses the antenna synthetic wave to generate phase distortion at the signal reception to carry out angle measuring jamming, such as traditional cross-eye jamming. However, cross-eye

Analysis of operating system diversity for intrusion tolerance [PDF]
One of the key benefits of using intrusion-tolerant systems is the possibility of ensuring correct behavior in the presence of attacks and intrusions. These security gains are directly dependent on the components exhibiting failure diversity.

Tolerance Design and Robust Study for The Joint Clearances of Landing Gear Retraction Mechanisms
Joint clearances inevitably affect the kinematic accuracy and robustness of landing gear retraction mechanisms. However, the complexity and uncertainty of the clearances lead to difficulty in establishing mathematic models and analyzing effects.

Multiple Solutions Starting from Real Shaped Beams in Equispaced Linear Arrays
In the present work, the theoretical basis of the multiplicity of solutions obtained from an initial real symmetric distribution is derived. This initial solution is devoted to generating an equivalent pure real shaped-beam pattern for a concrete ...
