A. Pendulum-Type Testing apparatus

Self testing quantum apparatus

We study, in the context of quantum information and quantum communication, a configuration of devices that includes (1) a source of some unknown bipartite quantum state that is claimed to be the Bell state Φ and (2) two spatially separated but otherwise unknown measurement apparatus, one on each side, that are each claimed to execute an orthogonal measurement at an angle θ ∈ {−π/8, 0, π/8} that...

Degenerate Equations of Pendulum-type

Design of Rover Wheel Testing Apparatus

A Rover’s wheel performance is one of the limiting factors in its ability to successfully traverse other planets. More research focusing on wheel materials, design, and optimized tread patterns needs to be conducted so that a rover can reach more of its potential. A wheel test bed is being fabricated to test new wheel designs and to collect data which will be used to map the relationship betwee...

An apparatus for pseudo-deterministic testing

Pseudo-random testing is popularly used, particularly in Built-In Self Test (BIST) applications. To achieve a desired fault coverage, pseudo-random patterns are often supplemented with few deterministic patterns. When positions of deterministic patterns in the pseudo-random sequence are known a priori, pseudo-random sub-sequences can be chosen such that they cover these deterministic patterns. ...

Subharmonic Oscillations of Forced Pendulum-Type Equations

where f is periodic with minimal period T and mean value zero. We have in mind as a particular case the pendulum equation, where g(x) = A sin x. First results on the existence of subharmonic orbits in a neighborhood of a given periodic motion were obtained by Birkhoff and Lewis (cf. [3] and [ 143) by perturbation-type techniques. Rabinowitz [ 151 was able to prove the existence of subharmonic s...
