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...
متن کاملFatigue Testing
Fatigue is the progressive, localized, permanent structural change that occurs in materials subjected to fluctuating stresses and strains that may result in cracks or fracture after a sufficient number of fluctuations. Fatigue fractures are caused by the simultaneous action of cyclic stress, tensile stress and plastic strain. If any one of these three is not present, fatigue cracking will not i...
متن کاملRedesigning axial-axial (biaxial) cruciform specimens for very high cycle fatigue ultrasonic testing machines
The necessity to increase performances in terms of lifetime and security in mechanical components or structures is the motivation for intense research in fatigue. Applications range from aeronautics to medical devices. With the development of new materials, there is no longer a fatigue limit in the classical sense, where it was accepted that the fatigue limit is the stress level such that there...
متن کاملAnkle Fatigue Classification Using Support Vector Machines
Fall accidents are a significant problem for the elderly, in terms of both human suffering and economic losses. Localized muscle fatigue is a potential risk factor for slip-induced falls as muscle fatigue adversely affects proprioception, movement coordination and muscle reaction times leading to postural instability and gait changes. Specifically, fatigue in ankle is associated with decline in...
متن کاملDesign 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...
